help guideline authors and first aid providers under-stand how to adapt evidence-based guidelines to various emergency situations-from low-resource and remote settings to urban incidents-and across different provider skill levels-from untrained bystanders to health care pro-fessionals. In our future work, we will combine clear rec-ommendations with practical examples, which will help practitioners to better understand both the applications and limitations of first aid evidence, including when to seek additional help. Since 2024, we have also started applying an equity lens on our CoSTRs; included studies will be screened regarding content in PROGRESS Plus, ${ }^{5}$ and an equity statement will be found in every CoSTR.

GENERAL PRINCIPLES

Use of Pulse Oximetry (FA 7010, ScopRev 2023)

Pulse oximetry has been used for monitoring of hospital-ized patients at risk of hypoxemia as well as, more recent-ly, for home use during the COVID-19 pandemic. The FA Task Force considered it timely to undertake a ScopRev6 in 2022 to identify evidence relating to the use of pulse oximetry as a component of first aid assessment of acute symptoms associated with illness or injury. Details of this review can be found in the 2023 CoSTR summary.6

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children in out-of-hospital or home settings with an acute illness or injury

● Intervention: Use of pulse oximetry in addition to standard first aid assessment

● Comparator: Standard first aid assessment without the use of pulse oximetry

• Outcome: Any clinical outcome

• Time frame: All years up to November 16, 2022

Good Practice Statements (2023)

First aid providers who use pulse oximeters for the as-sessment of acute illness or injuries should be proficient in their use and understand their limitations, including equipment factors, environmental considerations, and patient-specific factors that may produce inaccurate and unreliable readings (good practice statement).

The use of a pulse oximeter for first aid assessment should not supersede or replace physical assessment(good practice statement).

Use of Supplemental Oxygen in the First Aid Setting(FA 7030, FA 519, FA 1549, FA 1649,ScopRev 2023, ScopRev 2024)

In the first aid setting, oxygen use has been described for loss of consciousness, diving emergencies, carbon monox-ide poisoning, and during cardiac arrest. A 2015 CoSTR ${ }^{7}$ and a 2023 ScopRev ${ }^{6}$ identified evidence of potential harm with oxygen use in acute exacerbations of chronic obstruc-tive pulmonary disease. A 2024 ScopRev ${ }^{8}$ expanded the search dates and inclusion criteria. Details of this review can be found in the 2024 CoSTR summary. ${ }^{9}$

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children who exhibit symp-toms or signs of shortness of breath, difficulty breathing or hypoxia outside of a hospital

• Intervention: Administration of oxygen by a first aid provider

● Comparator: No administration of oxygen

● Outcome: Functional outcome at discharge, 30 days, 60 days, 180 days, or 1 year, survival only at discharge, 30 days, 60 days, 180 days, or 1 year,length of hospital stay, resolution of symptoms or signs, patient comfort, therapeutic endpoints (eg,oxygenation, ventilation)

● Time frame: All years to December 2,2023

In 2023, the following good practice statement was for-mulated based on a limited search (FA 1549): "If first aid providers, trained to use oxygen, are administering supplemental oxygen to a person with known chronic ob-structive pulmonary disease, they should titrate the sup-plemental oxygen to maintain an oxygen saturation by pulse oximetry between 88% and 92%" The intent of the 2024 ScopRev was to look more broadly at the question of first aid oxygen use for adults and children with short-ness of breath, difficulty breathing, or hypoxia. No direct evidence was identified to suggest for or against first aid oxygen administration in this general population, and this remains a knowledge gap. However, the ScopRev yielded indirect evidence of harm with high-flow- or

Djarv et al

First Aid: 2025 CoSTR

high-concentration-supplemental oxygen in patients with chronic obstructive pulmonary disease in the emergency medical services setting. Based on this 2024 ScopRev,the good practice statement was slightly changed.

Good Practice Statement (2024)

When a first aid provider trained in oxygen use admin-isters oxygen to a person with acute difficulty breathing is who confirms that they have chronic obstructive pulmo-nary disease, it is suggested that pulse oximetry be used,and that oxygen be titrated to maintain an oxygen satura-tion between 88% and 92% (good practice statement).

Although high-flow oxygen should in general be avoided in patients with chronic obstructive pulmonary disease with difficulty breathing in the out-of-hospital setting, high-flow oxygen should not be withheld in the presence of life-threatening hypoxia(oxygen saturation<88%)(good practice statement).

The Recovery Position for Maintenance of Adequate Ventilation and the Prevention of Cardiac Arrest(FA 7040, FA 517, SysRev 2022)

The use of a recovery position for persons with a re-duced level of responsiveness has been taught in first aid courses for decades, primarily as a means to reduce the risk of aspiration of gastric contents. The original PICOST wording from a 2015 SysRev ${ }^{10}$ sought to com-pare a lateral, side-lying recovery position with a supine position in adults who are breathing and unresponsive in an out-of-hospital setting. The revised PICOST word-ing now clarifies the population of interest as adults and children with a reduced level of responsiveness of non-traumatic etiology and who do not require resuscative interventions. A ScopRev was last done in 2020, and this SysRev ${ }^{11}$ was undertaken with involvement of content experts from the FA and BLS Task Forces and included in the 2022 CoSTR summary. ${ }^{12}$

Population, Intervention, Comparator, Outcome,Study Designs, and Time Frame

● Population: Adults and children in the first aid set-ting who have a reduced level of responsiveness of nontraumatic etiology and do not require resuscita-tive interventions

● Intervention: Specific positioning (recovery position-ing [ie, various semiprone, lateral recumbent, side-lying, or three-quarters prone positions of the body])

● Comparator: Supine or other position

● Outcome:

- Critical: Survival, incidence of cardiac arrest,delayed detection of apnea and cardiac arrest

- Important: Need for airway management, inci-dence of aspiration, hypoxia, likelihood of cervi-cal spine injury, complications(venous occlusion,arterial insufficiency, arm discomfort/pain, dis-comfort/pain, aspiration pneumonia)

● Study designs: In addition to the standard criteria,case reports published in letter form were included.ScopRevs and SysRevs were included for discus-sion and to assure no primary papers were missed,but data were not extracted from these reviews.

● Time frame: All years to November 17,2021

Treatment Recommendations (2022)

When providing first said to a person with a decreased level of responsiveness of nontraumatic etiology and who does not require immediate resuscitative interven-tions, we suggest the use of the recovery position (weak recommendation, very low-certainty evidence).

When the recovery position is used, monitoring should continue for signs of airway occlusion, inadequate or agonal breathing, and unresponsiveness (good practice statement).

If body position, including the recovery position, is a factor impairing the first aid provider's ability to deter-mine the presence or absence of signs of life, the person should be immediately positioned supine and reassessed (good practice statement).

Persons found in positions associated with aspiration and positional asphyxia such as facedown, prone, or in neck and torso flexion positions should be repositioned supine for reassessment (good practice statement).

Recognition of Anaphylaxis (FA 7110, ScopRev 2023, EvUp 2025)

Population, Intervention, Comparator, Outcome,Study Design, and Time Frame

● Population: Adults and children experiencing anaphylaxis

● Intervention: Description of any specific symptoms to the first aid provider

● Comparator: Absence of any specific description

● Outcome: Anaphylaxis recognition (Critical)

● Study designs: In addition to the usual criteria, it was anticipated that there would be insufficient studies from which to draw a conclusion, so the minimum number of cases for a case series to be included was reduced from the default of 5 to 1 by the team.

● Time frame: October 28, 2023, to July 3, 2024

Summary of Evidence

Since the last ScopRev ${ }^{13}$ in 2022, we identified 734 unique articles, of which 4 articles ${ }^{6,14-16}$ were relevant.During the process to screen full text articles, it was noted that several studies reported an increase in knowl-edge of how to recognize anaphylaxis after educational interventions, viewing videos, health application (app) use,and coaching. Currently, there is insufficient evidence to justify conducting a SysRev on this topic. However,the available evidence suggests that a future SysRev on educational approaches for training lay providers to ef-fectively care for affected individuals is warranted.

Djarv et al

First Aid: 2025 CoSTR

Treatment Recommendation (2010)

First aid providers should not be expected to recognize the signs and symptoms of anaphylaxis without repeated episodes of training and encounters with persons with anaphylaxis (good practice statement).

Second Dose of Epinephrine for Anaphylaxis(FA 7111, FA 500, ScopRev 2021, EvUp 2025)

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children experiencing severe anaphylaxis requiring the use of epinephrine

● Intervention: Administration of a second dose of epinephrine

● Comparator: Administration of only one dose

● Outcome: Resolution of symptoms, adverse effects,complications

● Time frame: January 3,2021,to October 2,2024

Summary of Evidence

Since the last ScopRev ${ }^{17}$ published in 2021, one study ${ }^{18}$examining methods of administration was identified.There was insufficient literature to impact the previ-ous treatment recommendations. Updated SysRev or ScopRev is not recommended at this time.

Treatment Recommendations (2015)

We suggest a second dose of epinephrine be administered by autoinjector to adults and children with severe anaphy-laxis whose symptoms are not relieved by an initial dose(weak recommendation, very low-certainty evidence).

Removal of Foreign-Body Airway Obstruction(FA 7113, BLS 368, EvUp 2025)

This topic was moved from the BLS Task Force to FA Task Force in 2023 because of its relevance to first aid providers. A SysRev was last done in 2020 by BLS.19

Population, Intervention, Comparator, Outcome,Study Design, and Time Frame

● Population: Adults and children with foreign body airway obstruction in any setting

● Intervention: Interventions to remove foreign body airway obstruction, such as finger sweep, back slaps, abdominal thrusts, chest thrusts, and suction-based airway clearance devices

● Comparator: No action

● Outcome: Any clinical outcome

● Study designs: In addition to the standard crite-ria, case reports of injuries or complications were also eligible. Unpublished studies (eg, conference abstracts, trial protocols), animal studies, manikin studies and cadaver studies were excluded.

● Time frame: August 2019 through September 20,2024

Summary of Evidence

This EvUp identified 17 new publications ${ }^{20-36}$ since the previous SysRev ${ }^{20}$ in 2019. The evidence suggests that regardless of which treatment is provided first, it is com-mon for more than one intervention to be required for relief of a foreign body airway obstruction. One study suggests that back blows are more effective than chest or abdominal thrusts. ${ }^{29}$ Airway clearance devices are increasing in prevalence. Currently, there are no treat-ment recommendations regarding these devices. An up-dated SysRev is warranted. After discussion, clarification regarding age range was added to one of the existing treatment recommendations.

Treatment Recommendation (BLS 2020)

We suggest that back slaps are used initially in patients with a foreign body airway obstruction and an ineffective cough(weak recommendation, very low-certainty evidence).

We suggest that abdominal thrusts are used in adults and children(over 1 year of age) with a foreign body airway obstruction and an ineffective cough where back slaps are ineffective (weak recommendation, very low-certainty evidence).

We suggest that rescuers consider the manual extrac-tion of visible items in the mouth (weak recommendation,very low-certainty evidence).

We suggest against the use of blind finger sweeps in patients with a foreign body airway obstruction (weak recommendation, very low-certainty evidence).

We suggest that appropriately skilled individuals con-sider the use of Magill forceps to remove foreign body airway obstruction in OHCA patients with a foreign body airway obstruction (weak recommendation, very low-certainty evidence).

We suggest that chest thrusts are used in uncon-scious patients with a foreign body airway obstruction(weak recommendation, very low-certainty evidence).

We suggest that bystanders undertake interventions to support foreign body airway obstruction removal as soon as possible after recognition (weak recommenda-tion, very low-certainty evidence).

Potential Harms From Bronchodilator Administration (FA 7122, ScopRev 2023)

Persons with asthma exacerbations benefit from adminis-tration of bronchodilators. However, it is unknown wheth-er first aid providers can appropriately identify asthma exacerbations, and it is unknown whether bronchodila-tors could result in harm if administered to individuals with undifferentiated respiratory symptoms. Details of this review can be found in the 2023 CoSTR summary.6

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children in any setting with acute undifferentiated respiratory problems

Djárv et al

First Aid: 2025 CoSTR

● Intervention: Administration of any type of inhaled bronchodilator (eg, $\beta$ -agonists, anticholinergics)

● Comparator: No administration of an inhaled bronchodilator

● Outcomes: Survival, dysrhythmia, cardiac isch-emia, hypokalemia, need for emergency depart-ment treatment, need for hospitalization, and time to treatment

● Time frame: All years to November 2,2022

Treatment Recommendation (2015, Unchanged)

When an individual with asthma is experiencing dif-ficulty breathing, we suggest that trained first aid providers assist the individual with administration of a bronchodilator(eg, $\beta$-agonists, anticholinergics)

Early Aspirin for Chest Pain (FA 7140, FA 586,EvUp 2025)

Population, Intervention, Comparator, Outcome,Study Designs, and Time Frame

● Population: Adults who experience nontraumatic chest pain

● Intervention: Early or first aid administration of aspirin

● Comparator: Later or in-hospital administration of aspirin

● Outcome: Any outcome

● Time frame: October 1, 2019, to September 30,2024

Summary of Evidence

Since the last SysRev$^{37}$ completed for 2019, 98 articles were screened, and none were relevant for the topic. Of note, one study$^{38}$ described increased risk of bleeding in chest pain patients administered aspirin or clopidogrel(or both) and finally diagnosed as type A aortic dissec-tion necessitating surgical intervention. A new review is currently not warranted.

Treatment Recommendation (2019)

For adults with nontraumatic chest pain, we suggest the early administration of aspirin as a first aid inter-vention compared with late, in-hospital, administration of aspirin(weak recommendation, very low-certainty evidence).

Methods of Glucose Administration for Hypoglycemia(FA 7161, FA 1585, EvUp 2025)

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children in any setting(in-hospital or out-of-hospital) with(suspected)hypoglycemia

● Intervention: Administration of glucose by any route appropriate for use by first aid providers

● Comparator: Administration of glucose by another route appropriate for first aid providers

● Outcomes: Resolution of symptoms; time to resolu-tion of symptoms; blood or plasma glucose concen-tration at 20 minutes; resolution of hypoglycemia;time to resolution of hypoglycemia; any adverse event; administration delay

• Time frame: September 13, 2021, to October 18,2024

Summary of Evidence

Since the last SysRev39 in 2021, no relevant new studies were identified. An updated SysRev is not warranted.

Treatment Recommendations (2021)

We recommend the use of oral glucose(swallowed) for individuals with suspected hypoglycemia who are con-scious and able to swallow(strong recommendation,very low-certainty evidence).

We suggest against buccal glucose administration compared with oral glucose administration for individu-als with suspected hypoglycemia who are conscious and able to swallow (weak recommendation, very low-cer-tainty evidence).

If oral glucose (for example, tablet) is not immedi-ately available, we suggest a combined oral plus bac-cal glucose (for example, glucose gel) administration for individuals with suspected hypoglycemia who are conscious and able to swallow (weak recommenda-tion, very low-certainty evidence).

We suggest the use of sublingual glucose adminis-tration for suspected hypoglycemia for children who may be uncooperative with the oral (swallowed) glucose administration route (weak recommendation, very low-certainty evidence).

Dietary Sugar Treatment for Hypoglycemia (FA 7162, FA 795, EvUp 2025)

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children with symptomatic hypoglycemia

● Intervention: Administration of dietary forms of sugar

● Comparator: Standard dose (15-20 g) of glucose tablets

• Outcomes: Time to resolution of symptoms, compli-cations, blood glucose level after treatment, hypo-glycemia(defined as the persistence of symptoms(yes/no) or recurrence of symptomatic hypoglyce-mia for more than 15 minutes after treatment), hos-pital length of stay

● Time frame: January 1,2020,to December 8,2024

Djär et al

First Aid:2025 CoSTR

Summary of Evidence

Since the last SysRev ${ }^{40}$ in 2017, we identified 3 relevant studies. One RCT ${ }^{41}$ with 3 arms in children with diabetes type 1 aged 12 to 16 years trekking for 5 days found no difference between any of the 3 arms: 0.3 g glucose prep-aration/kg, sugar fondant candies, and fruit juice. A narra-tive review ${ }^{42}$ explored the optimal dose of carbohydrates in nonsevere hypoglycemia; their conclusion was that most recover after 15 to 20 g, but individual strategies based on body weight or type of insulin delivery system might be relevant in future guidelines. One trial ${ }^{43}$ showed that oral intake of carbohydrates in patients with type 1 diabetes could be beneficial earlier, that is, at higher blood glucose levels than traditional cutoffs to avoid hypoglycemia. This might be relevant from a first aid perspective but is out of the scope for the current PICO(population, intervention,comparator, outcome). Based on these studies, additional reviews (systematic or scoping review) on this specific or similar topics are not recommended at this time.

Treatment Recommendations (2015, Unchanged)

We recommend that first aid providers administer glu-cose tablets for treatment of symptomatic hypoglycemia in conscious adults and children (strong recommenda-tion, low-certainty evidence).

We suggest that if glucose tablets are not available,various forms of dietary sugars such as small candies,singular cubes, jelly beans, or orange juice can be used to treat symptomatic hypoglycemia in conscious adults and children(weak recommendation, very low-certainty evidence).

There is insufficient evidence to make a recommenda-tion on the use of whole milk, cornstarch hydrolysate, and glucose solution, or glucose gels as compared with glucose tablets for the treatment of symptomatic hypoglycemia.

Recognition of Stroke (FA 7170, FA 801, EvUp 2025)

Population, Intervention, Comparator, Outcome,Study Design, and Time Frame

• Population: Adults with suspected acute stroke

● Intervention: Use of a rapid stroke scoring system or scale

● Comparator: Basic first aid assessment without the use of a stroke scale

• Outcomes:

- Critical: Time to treatment(eg, symptom onset to hospital/emergency department or hospi-tal admission)

-Important: Recognition of stroke, high sensitiv-ity and high specificity considered beneficial for diagnosis study, discharge with favorable neuro-logic status(increase considered beneficial), sur-vival with favorable neurologic outcome(increase considered beneficial), increased public/layer-son recognition of stroke signs

• Study designs: In addition to standard criteria,because it was anticipated that there would be insufficient studies from which to draw a conclusion,the minimum number of cases for a case series to be included was reduced from the default of 5 to 1.

● Time frame: May 26,2020,to June 31,2024

Summary of Evidence

Since the last SysRev ${ }^{44}$ in 2020, we did not identify any relevant articles. An update of the SysRev is not currently indicated.

Treatment Recommendations (2020)

We recommend that first aid providers use stroke as-sessment scales/tools for adults with suspected acute stroke(strong recommendation, low-certainty evidence).

For first aid, we suggest the use of the Face, Arms,Speech, Time tool; Melbourne Ambulance Stroke Scale;Cincinnati Prephospital Stroke Scale; or Los Angeles Pre-hospital Stroke Screen for stroke assessment(weak rec-ommendation, low-certainty evidence).

For first aid, we suggest the use of stroke assess-ment scales/tools that include blood glucose measure-ment when available, such as the Melbourne Ambulance Stroke Scale or Los Angeles Prehospital Stroke Screen,to increase specificity of stroke recognition (weak rec-ommendation, low-certainty evidence).

For first aid, we suggest the use of the Face, Arms,Speech, and Time tool or Cincinnati Prehospital Stroke Stroke scale stroke assessment when blood glucose mea-surement is unavailable (weak recommendation, low-certainty evidence).

Recognition of Sepsis (FA 7180, ScopRev 2024)

A significant proportion of preventable deaths worldwide are caused by sepsis, and early detection and treatment is beneficial. No review was undertaken until 2024, when the task force prioritized a ScopRev on the recognition and awareness of sepsis by first aid providers evaluating adults with an acute illness. The completed ScopRev45 and CoSTR can be found in the 2024 CoSTR summary. ${ }^{8}$

Population, Intervention, Comparator, Outcome,Study Design, and Time Frame

● Population: Adults who are being evaluated by a first aid provider for an acute illness

● Intervention: The presence of any specific signs or symptoms (ie, pale, blue, or mottled skin, lips,tongue, gums, or nails; nonblanching rash; difficulty breathing or rapid respiratory rates; rigors/shiver-ing; lack of urination in a day; muscle pain; confu-sion; or slurred speech)

● Comparator: Fever (≥38 ℃[≥100.4°F]) with signs of infection

● Outcomes: Recognition of a seriously ill person requiring hospitalization or evaluation by a physician for sepsis and increased awareness of sepsis

Djarv et al

First Aid: 2025 CoSTR

● Study designs: In addition to the standard crite-ria, gray literature, social media posts, non-peer-reviewed studies, unpublished studies, conference abstracts, and trial protocols were eligible for inclusion.

● Time frame: All years to December 2,2023

Good Practice Statement (2024)

Those providing first aid should consider an infection in any person who presents with an acute illness, and if the illness is associated with any abnormal signs or symp-toms, they should urgently seek further medical evalua-tion (good practice statement).

Interventions Administered by Lay Providers for the Treatment of Postpartum Hemorrhage(FA 7337, ScopRev 2025)

Rationale for Review

Postpartum hemorrhage is the leading cause of ma-ternal mortality and morbidity worldwide, particularly in low-income countries with limited resources.46 Early recognition and prompt treatment have the ability to prevent many deaths and long term health challeng-es.47 The FA Task Force performed a ScopRev to exam-ine interventions for treating postpartum hemorrhage by lay providers, a topic that had not been reviewed by ILCOR before. The full report of the ScopRev can be found online.49

Population, Intervention, Comparator, Outcome,Study Designs, and Time Frame

● Population: First aid or emergency care adminis-tered by a lay provider to anyone experiencing post-partum hemorrhage

● Intervention: Interventions that are classified as emergency care include those that fall within the following 2 categories:

- Physical interventions: Examples of physical inter-ventions administered by a lay provider include external uterine massage, bimanual compression,aortic compression, antishock garment, manual removal of placenta, or manual removal of clots.

- Medications/Pharmaceuticals: Examples of medical interventions administered by a lay pro-vider include iron supplementation, prostaglandin E1/misoprostol, or any other drug that may be accessible without intervention from a medical professional.

● Excluded interventions include those that require hospital/clinic support through medical profes-sionals such as a blood transfusion, or any invasive surgical intervention such as curetage, uterine or pelvic artery ligation, uterine tamponade, or hysterectomy.

● Comparator: No intervention

● Outcomes: Any clinical outcome

● Study designs: In addition to standard criteria, gray literature including social media, non-peer-reviewed studies, unpublished studies, case reports, confer-ence abstracts and trial protocols were eligible for inclusion.

● Time frame: All years to October 22, 2024

Summary of Evidence

Sixteen articles were included in this ScopRev, includ-ing 1 opinion article, ${ }^{50}$ 2 observational training or perfor-mance assessment articles, ${ }^{51,52}$ 5 qualitative studies, ${ }^{53-57}$3 cross-sectional studies, ${ }^{58-60}$ 2 guidelines, ${ }^{61,62}$ 2 non-RCTs, ${ }^{63,64}$ and 1 RCT. ${ }^{49}$ Interventions in these studies were primarily implemented by traditional birth atten-dants or similar persons with minimal formal training.

Three drugs were discussed: misoprostol, oxytocin,and ergotamine. All medications were administered orally,rectally, or intramuscularly and were therefore consid-ered compatible with first aid practices. Misoprostol was administered rectally or orally in doses ranging from 400 to 1000 mcg.60-65 Evidence on misoprostol came from the RCT,65 both non-RCTs,63,64 a cross-sectional study,60 and both guidelines.61,62 Oxytocin was discussed in both guidelines61,62 and 1 cross-sectional study58 in the con-text of a Unject autoinjector, which keeps the medication cool and enables lay administration.58,61,62 Ergotamine/ergometrine was kept and used in lay settings56,58 and was further recommended for intramuscular delivery of low-resource settings in both guidelines.61,62

Controlled cord traction was not recommended for use by unskilled birth attendants in both guidelines. ${ }^{61,62}$In lower-resource settings, some unskilled providers applied it in the absence of skilled birth attendants. ${ }^{54}$

The use of uterine balloon tamponade was found to be effective and simple to use by community providers in 1 qualitative study.65 A novel intrauterine tamponade device developed for administration by people with mini-mal training increased usability.51

The use of a compression lower body suit, so-called nonpeumatic antishock garment, which forces blood back to the vital organs, was highlighted by one guide-line and one opinion article.50,61 These garments are con-ventionally used only in health care facilities but were described as having high potential for application by lay providers. Herbal medicines commonly used by traditional birth attendants were also addressed in several qualita-tive and cross-sectional studies and guidelines53,54,56-59 but discouraged based on harms or lack of benefit.56

Task Force Insights

Most birth attendants globally are untrained or trained to a level that would align with a first aid provider outside of the birthing or obstetrical domain. ${ }^{67}$ Determining the difference between preventing and treating postpartum hemorrhage can be difficult, especially when interven-tions used for prevention and treatment are often the same (eg, manual external uterine massage, oxytocin).

Djarv et al

First Aid:2025 CoSTR

Most studies were qualitative and retrospective in na-ture, leading to an increased risk of bias and overall low certainty of evidence. Only 1 RCT65 was performed and evaluated only the efficacy of misoprostol.65

Although we excluded studies on conventional uterine balloon tamponade, we included studies on innovative devices useable by nonskilled providers.

This ScopRev triggered a SysRev on manual uterine massage(FA 7336), which is included below.

● Most studies were qualitative and retrospective in nature, leading to an increased risk of bias and overall low certainty of evidence.

Manual Uterine Massage for Postpartum Hemorrhage(FA 7336, SysRev 2025)

Rationale for Review

The FA Task Force undertook a SysRev on this topic be-cause many international guidelines and other knowledge syntheses recommend external uterine massageus for the pre-vention and management of postpartum hemorrhage.4768-74 Postpartum hemorrhage is a major cause of global morbidity and mortality, particularly in lower-resource settings where most birth attendants have limited professional health edu-cation and may be considered lay or first aid providers.67 Manual external uterine massageus is a simple and safe phys-ical maneuver similar to other manual maneuvers taught to first aid providers and may reduce morbidity and mortality.This SysRev was registered in Prospective Register of Sys-tematic Reviews (PROSPERO) (CRD42024572048).The full CoSTR can be found online. ${ }^{75}$

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Those experiencing postpartum hemorrhage

● Intervention: Manual external uterine massage immunated administered by a lay provider

● Comparator: Any other first aid intervention to treat postpartum hemorrhaging, or no intervention

• Outcomes:

- Critical: Maternal survival, blood loss

-Important: Future fertility, surgical intervention,organ dysfunction, pain, and blood transfusion

● Time frame: All years to March 22,2024

Consensus on Science

We identified a single RCT ${}^{76}$ including 127 women who had recently given birth in Kenya and were advised to perform self-massage cue and by an alarm every 15 min-utes for the first 120 minutes after birth. The study re-ported better compliance with an alarm every 15 minutes but a non-statistically significant difference in the impor-

tant outcomes of blood loss and blood transfusion (weak recommendation, very low-certainty evidence).

Treatment Recommendation (2025)

We suggest external uterine massage, including self-massage, in the immediate postpartum period in com-parison with no intervention to prevent postpartum hemorrhage, which can lead to maternal death (weak recommendation, very low-certainty evidence).

Justification and Evidence-to-Decision Framework Highlights

The complete evidence-to-decision table is provided in Appendix A.

External uterine massage is a ubiquitous standard for professional birth attendants and first responders for the prevention and management of postpartum hemor-rhage.68,73,74,77 External uterine massage is a simple and safe physical maneuver, equivalent to other physical interventions routinely taught to first aid providers (eg,moving a patient, splinting an injured limb, applying direct pressure or a tournament to a bleeding wound).

Postpartum hemorrhage is a major source of global morbidity and mortality, especially in settings with lim-ited or no access to professional health care providers.Therefore, recommendations that limit external uterine massage to health care professionals would potentially compound health inequities. Although the identified study did not demonstrate a statistically significant reduction in blood loss or blood transfusion, it did demonstrate that external uterine massage can be taught to lay providers.

Task Force Knowledge Gaps

● The importance of the pressure and firmness of the uterine massage for the effectiveness of the intervention; the included study could not measure or regulate the strength or firmness of the uterine massage by study participants and did not describe if or how this was controlled or taught.

● More studies examining massage by lay providers,such as traditional birth attendants, are needed.

● Whether manual uterine massage affects maternal outcome beyond 120 minutes

Use of Naloxone During Resuscitation for Suspected Opioid-Associated Emergencies(FA 7442,BLS 811,EvUp 2025)

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children with suspected opioid-associated cardiac or respiratory arrest in the prehospital setting

● Intervention: Bystander naloxone administration(intramuscular or intranasal), in addition to standard CPR

● Comparator: Standard CPR only

Djarv et al

First Aid: 2025 CoSTR

• Outcomes: Any clinical outcome

● Time frame: July 2019 to December 12,2023

Summary of Evidence

This PICO question was transferred from the BLS Task Force to the FA Task Force after 2020. Since the last SysRev in 2020, 356 new titles were screened.No new evidence was identified, and an update to the SysRev is not indicated. The current ILCOR practice is to use good practice statements in place of treat-ment recommendations for cases in which there is in-sufficient evidence for a treatment recommendation,but the task force thinks guidance is warranted. The previous treatment recommendation based on expert consensus from 2020 has therefore been changed to a good practice statement.

Good Practice Statement (2020)

We suggest CPR be started without delay in any uncon-scious person not breathing normally and that naloxone be used by lay rescuers in suspected opioid-related re-spiratory or circulatory arrest (good practice statement).

Prevention of Syncope With Counter-Pressure Maneuvers (FA 7550, FA 798, EvUp 2025)

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children with signs and symptoms of faintness or presyncope of suspected vasojave argothostic origin

● Intervention: Interventions such as counter-pressure maneuvers, body positioning, hydration, or other

● Comparator: No intervention or any other intervention

● Outcomes: Avoiding or preventing syncope or transient loss of consciousness, resolution of symptoms or symptoms response, hemodynamic status(including systolic and diastolic blood pres-sure, change in heart rate, cardiac output, stroke volume, or blood flow velocity), recurrences of presyncope or syncope, time to resolution of symptoms, adverse events, admission to hospital,quality of life

● Time frame: December 2, 2021, to December 2,2023

Summary of Evidence

Since the 2019 CoSTR summary, ${}^{78,79}$ 2 SysRev ${}^{80,81}$ were identified on the use of physical counter-pressure ma-neuvers for the prevention of syncope. Additionally, 1 RCT82 was found assessing counter-pressure maneu-vers during dental extraction in patients with a history of dental anxiety and previous syncope. The SysRevs and single RCT support the conclusions of the 2019 SysRev and CoSTR. ${}^{78,79,83}$ An updated SysRev is not indicated at this time.

Treatment Recommendation (2019)

We recommend the use of any type of physical counter-pressure maneuver by individuals with acute symptoms of presyncope due to vasovagal or orthostatic causes in the first aid setting (strong recommendation, low-certainty and very low-certainty evidence).

We suggest that lower body physical counter-pressure maneuvers are preferable to upper body and abdominal physical counter-pressure maneuvers (weak recommen-dation, very low-certainity evidence).

Unintentional Injury From Laypersons Providing Chest Compressions to Patients Who Are Not in Cardiac Arrest (FA 7670, BLS 353, SysRev 2025)

Rationale for Review

Delivery of high-quality chest compressions is a key step in the Chain of Survival for patients in cardiac ar-rest. Immediate CPR initiated by laypersons is associ-ated with improved outcomes. However, there may be a reluctance among laypersons to initiate CPR for fear of causing unintentional injuries. Since the last review ${ }^{84}$ in 2020, the topic has been moved from the ILCOR BLS Task Force to FA Task Force, prompting a new SysRev ${ }^{85}$ focusing on layperson rescuers. The term harm was changed to unintentional injury. The SysRev was registered before initiation (PROSPERO Registra-tion CRD42023476764). The complete CoSTR can be found online. ${ }^{86}$

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children outside of a hospital who are not in cardiac arrest

● Intervention: Provision of chest compressions by laypersons

● Comparator: No use of chest compressions

• Outcomes: Survival with favorable neurological out-come at discharge, 30 days, 60 days, 180 days, or 1 year; unintentional physical injury(previously harm)(eg, rib fracture, bleeding); risk of unintentional injury(eg, aspiration, rhabdomyolysis)

● Time frame: All years to September 17,2024

Consensus on Science

Since the last SysRev,1 new study87 was identified. In the total of 5 studies,87-91 including 1031 patients not in cardiac arrest who received CPR, 7 (0.7%) experienced unintentional physical injury. Additionally, 2 (0.2%) pa-tients had a risk of unintentional injuries and a further 24(2%) had symptoms such as chest pain or discomfort.No deaths caused by CPR were reported, but 61 (6%)patients died before being discharged from the hospital.The included studies were too heterogeneous to perform a meta-analysis.

Djär et al

First Aid: 2025 CoSTR

Prior Treatment Recommendations(2020)

We recommend that laypersons initiate CPR for pre-sumed cardiac arrest without concerns of harm to pa-tients not in cardiac arrest(strong recommendation, very low-certainty evidence).

Treatment Recommendations (2025)

We recommend that laypersons initiate CPR for pre-sumed cardiac arrest without concerns of causing un-intentional injury(strong recommendation, low-certainty evidence).

We recommend that other rescuers(eg, trained bystanders, health care professionals, and those with a duty to respond) initiate CPR for presumed cardiac arrest without concerns of causing unintentional injury to persons not in cardiac arrest (good practice statement).

Justification and Evidence-to-Decision Framework Highlights

The complete evidence-to-decision table is provided in Appendix A.

In making this discordant recommendation, the FA Task Force placed a higher value on the potential survival ben-efits of CPR initiated by laypersons for patients in cardiac arrest and a lower value on the low risk of injury in patients not in cardiac arrest. The intention of this recommenda-tion is to strongly encourage and support laypersons who are willing to initiate CPR in any setting when they believe someone has suffered a cardiac arrest.

The included studies focused on laypersons and not on other persons, such as health care professionals or those with a duty to respond, but the task force believes that the benefit of starting CPR outweighs the harm and used the indirect evidence to make a good practice statement.

The incidence of chest wall bone fractures was sub-stantially lower than the incidence reported after CPR in patients who were in cardiac arrest. This could be because of the shorter duration of CPR (most often <5 minutes) ${ }^{85}$ initiated by laypersons and stopped by professional res-cuers. However, the possibility of underreporting due to nonsystematic diagnostic studies cannot be excluded.

The task force discussed how the use of a structured equity assessment, such as the PROGRESS Plus tool, ${ }^{5}$ might increase equity-focused reporting. The proportion of men and women were roughly equal in the included studies. However, in 3 studies, the layperson often had some kind of relationship with the patient, as either a fam-ily member or personnel at a nursing home. Both types of relationships might be accompanied by fear of causing an injury, and still they most likely would be more willing to cause an unintentional injury if it comes with survival.

Task Force Knowledge Gaps

● More studies are needed with robust methodology to identify unintentional injuries and provide follow-up after hospital discharge.

● The incidence and pattern of injuries from CPR given to children not in cardiac arrest.

● Few aspects of equity were reported in studies.

Spinal Motion Restriction for Possible Traumatic Cervical Spinal Injury (FA 7311, FA 7312,FA 1547, ScopRev 2025)

Rationale for Review

In many countries, spinal motion restriction protocols are used by emergency medical service professionals, but similar guidance for first aid providers continues to be debated. There is ongoing controversy around the use of cervical collars and other devices by both trained emer-gency medical service providers and lay first aid provid-ers and concern regarding the evidence of harm from cervical collars, as well as the risk of secondary spinal cord injury after the initial trauma. Manual stabilization of spinal injury(FA 7312, FA 1547) was included in this new PICO.This ScopRev92 encompasses literature published in the last 25 years, including previous work done by the 2015 FA Task Force.37,93 The full report of the ScopRev can be found online.

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children with possible trau-matic cervical spinal injury

● Intervention: Cervical spinal motion restriction per-formed by a trained first aid provider

● Comparator: No cervical spinal motion restriction, or another type of cervical spinal motion restriction

● Outcome: Any clinical outcome

● Time frame: January 1,1999,to July 31,2024

Summary of Evidence

We included 66 studies, including 22 RCTs,94-115 19 non-RCTs,116-134 8 cohort studies,135-142 3 interrupted time series,143-145 7 case series,146-152 and 7 retrospec-tive chart reviews.153-159 Out of a total of 46 experimental studies,36(78%) were performed in live human volun-teers,94-99,101-103,105-116,119-124,126,128-130,133,134,144,145,150,152 and 5 primarily used human cadaver mod-els117,118,127,131,132 to assess range of cervical motion and adverse effects of spinal motion restriction. The 20 observational studies 135-143,146-149,153-159 mainly investi-gated the risk of secondary spinal injury, functional out-comes, and adverse effects of spinal motion restriction in trauma patients.

Evidence for the effectiveness of spinal motion restriction compared with no spinal motion restric-tion was provided in 46 studies, 94,97,99-101,105,107-111,114-118,120,121,123-125,127,130,131,133,135,136,138,139,143-157,159 $\overline{\text { (n=35) comparing cervical collar use with no cervical}}$ collar use with no cervical collar use. Together, these studies indicated that cervical collars decrease the range of cervical motion but lead to

impaired respiratory and swallowing function as well as increased intracranial pressure.

Twenty-nine studies94,97-100,102-104,106-113,115,117,120,121,123,126,128,131-134,140,146 compared multiple types of spinal motion restriction. Four studies compared soft foam with rigid collars,117,120,131,146 suggesting that the use of soft foam collars allows significantly more cervical motion117,120,131 but is not associated with an increased risk of secondary spinal injury.146 One study106 showed no significant dif-ferences in range of cervical motion between improvised(eg, a folded fleece jacket) and commercially available collars. Five studies98,99,103,108,113 showed that in com-parison with 2-piece rigid collars, one-piece rigid collars result in greater restriction of cervical motion and cause significantly lower increases in jugular venous pressure but create higher interface pressures.

The effectiveness of spinal motion restriction meth-ods or devices during simulated extrication from vehicles was assessed in 4 studies.95,96,122,129 These suggested that collar application in combination with unassisted self-extrication, whereby a person is asked to leave the vehicle themselves without further instructions, creates the least range of cervical motion.

Finally, 5 studies ${ }^{135,137,141,142,158}$ found no significant difference in the incidence of spinal cord injuries or functional outcomes of trauma patients before and after the implementation of spinal motion restriction protocols.

Task Force Insights

Most of the evidence comes from experimental stud-ies in healthy young adult volunteers or human cadav-ers. Therefore, the findings may not be generalizable to adults and children with possible traumatic cervical spine injury. Also, 40% of all included studies were conducted in the United States.

Only 2 studies ${ }^{106,120}$ looked at improvised devices for spinal motion restriction, which may be particularly useful for first aid in low-resource settings. In contrast,many experimental studies included direct comparisons of multiple commercially available cervical collars. There was marked heterogeneity across studies in the different brands or specific features of cervical collars, including in their design (1-piece or 2-piece) and structure (rigid,semirigid, soft,improvised).

The task force recognizes that trained first aid provid-ers in selected circumstances(eg, ski patrols and life-guards) might be capable of using cervical collars but concluded that formal data synthesis and determination of the certainty of the vast evidence base is required to confidently withdraw the existing treatment recommen-dation or to formulate any further treatment recommen-dation or good practice statement. A future systematic review of protocol-based selective spinal motion restric-tion may provide additional evidence for a good practice statement.

This ScopRev provides a comprehensive overview of the available evidence and may serve as a basis for future SysRevs on one or more narrowly defined PICO questions, which will be discussed in the upcoming year within the task force. Currently, the 2015 treatment rec-ommendation remains unchanged.

Treatment Recommendation (2015)

We suggest against the use of cervical collars by first aid providers (weak recommendation, very low-certainty evidence).

Cryotherapy for Epistaxis(FA 7151, ScopRev 2021)

Cryotherapy, or cooling, has been suggested to shrink nasal mucosa and cause vasoconstriction as a method to aid hemostasis. For 2021, the FA Task Force prioritized the topic for a ScopRev to identify the scientific evidence behind such recommendations for the use of cryotherapy for epistaxis. Details of this ScopRev ${}^{160}$ can be found in the 2021 CoSTR summary. ${ }^{161}$

Population, Intervention, Comparator, Outcome,Study Design, and Time Frame

● Population: Adults and children receiving first aid for acute epistaxis

• Intervention: Cryotherapy alone or cryotherapy with nose pinching

● Comparator: Nosie pinching alone

● Outcome: Time to hemostasis control (minutes),hemostasis (yes/no), reduction of nasal blood vol-ume (volume), reduction of pain, need for follow-up care (yes/no), adverse events (yes/no), recovery time (days/min), reduction of swelling (volume)

● Study designs: In addition to the standard criteria,gray literature was available for inclusion. Further,we examined ILCOR's 8 member councils' and their subcouncils' websites.

● Time frame: All years to January 14,2021; a gray literature search was conducted December 28,2020

There was insufficient evidence to support a good prac-tice statement.

Manual Pressure and Pressure Devices for Bleeding(FA 7331,FA 530, SysRev 2021,EvUp 2025)

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children with severe, life-threatening external bleeding from an extremity

● Intervention: Direct pressure to the wound with a compression dressing, compression bandage, com-pression device, wound clamp, application of a junc-tional pressure, proximal manual pressure

• Comparator: Direct manual pressure

• Outcomes:

- Critical: Mortality due to bleeding; cessation of bleeding, achieving hemostasis; time to achieving hemostasis

-Important: Mortality from any cause; decrease in bleeding; complications/adverse effects(eg, wound infection, limb loss, rebleeding, pain related to an intervention)

● Time frame: November 22,2019, to July 2,2024

Summary of Evidence

Since the 2021 SysRev,162 7 studies163-169 were identified on the use of pressure devices or pressure points compared with direct manual pressure. While findings in these studies suggest some potential benefits for the use of pressure points or pressure devices in some settings, the results are confounded by the indirect nature of the evidence and po-tential bias. Given these limitations, a ScopRev or SysRev is not warranted at this time. Future ScopRev or SysRev should clarify the definitions of devices for manual pres-sure versus limb tourniquets. After discussion, wording was added to the existing 2021 treatment recommendations to clarify that the recommendation for direct manual pressure is specific to bleeding from an extremity.

Treatment Recommendation (2021)

We recommend that first aid providers use direct manual compression compared with the use of external com-pression devises or pressure dressings/bandages for se-vere life-threatening external bleeding from an extremity(strong recommendation, very low-certainty evidence).

We recommend against the use of pressure points compared with the use of direct pressure by first aid providers for severe, life-threatening external bleeding(strong recommendation, very low-certainty evidence).

Type of Tourniquets Alone or in Combinations With Other Methods of Achieving Hemostasis(FA 7333, FA 768, SysRev 2021, EvUp 2025)

The original PICO was a mega-PICO with several sub-PICOrs. ${ }^{162}$ The EvUp below focused on one of the sub-PICO s.

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults of children with severe, life-threatening external bleeding from an extremity

● Intervention: Improvised tourniquets, direct manual pressure or direct pressure to the wound with a compression dressing, compression bandage or compression device, hemostatic dressings

● Comparator: Manufactured tourniquets

• Outcomes:

- Critical: Mortality due to bleeding; cessation of bleeding or achieving hemostasis; time to achiev-ing hemostasis

-Important: Mortality from any cause, decrease in bleeding, complications/adverse effects(eg,wound infection, limb loss,rebleeding, pain related to an intervention)

● Time frame: November 22,2019,to June 29,2024

Summary of Evidence

Since the last SysRev162 in 2021, 29 articles170-198 were identified regarding the use of tourniquets for life-threatening extremity bleeding. The data support the use of tourniquets compared with no use of a tourniquet for life-threatening extremity hemorrhage. Studies demon-strate reduced in-hospital mortality and a lower incidence of shock when tourniquets are used. Evidence supports the use of commercial tourniquets compared with im-provised tourniquets because commercial tourniquets achieve better arterial occlusion and are simpler to apply.Therefore, based on this EvUp, a SysRev on tourniquet use in children was undertaken and is included here.

Treatment Recommendation (2020)

We suggest that first aid providers use a tourniquet in comparison with direct manual pressure alone for severe,life-threatening external bleeding that is amenable to the low-certainty evidence).

We suggest that first aid providers use a tourni-quet rather than a hemostatic dressing for severe, life-threatening external bleeding that is amenable to the use of a tourniquet (weak recommendation, very low-certainty evidence).

Types of Pediatric Tourniquets (FA 7333, FA 768,SysRev,2021 CoSTR Summary)

A SysRev of the use of tourniquets in the children(<19 years of age) was conducted for the 2021 CoSTR sum-mary.${}^{161}$

Population, Intervention, Comparator, Outcome,Study Designs, and Time Frame

● Population: Children(<19 years of age) with severe,life-threatening bleeding from an extremity wound

Djär et al

First Aid: 2025 CoSTR

● Intervention: Commercial elastic wrap tourniquet or commercial ratcheting tourniquet

● Comparator: Commercial windlass rod-type tourniquet

● Outcome: Mortality, control of bleeding (includ-ing surrogate outcome of obliteration of Doppler pulses), blood loss, shock/hypotension, and adverse events

• Study designs: In addition to standard criteria, mod-eling studies, studies of tourniquets applied solely to maintain a bloodless surgical field, and those relat-ing only to education were excluded.

● Time frame: All years to October 1,2020

Treatment Recommendations (2021)

We suggest the use of a manufactured windlass tour-niquet for the management of life-threatening extremity bleeding in children (weak recommendation, very low-certainty evidence).

We are unable to recommend for or against the use of other tourniquet types in children because of lack of evidence.

For infants and children with extremities that are too small to allow the snug application of a tourniquet before activating the circumferential tightening mechanism, we recommend the use of direct manual pressure with or without the application of a hemostatic trauma dressing(good practice statement).

Hemostatic Dressing (FA 7334, FA 769, EvUp 2025)

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children with severe, life-threatening external bleeding

● Intervention: Hemostatic dressings with or without direct pressure (manual or pressure to the wound with a compression dressing, compression ban-dage, or compression device)

● Comparator: Direct manual pressure or direct pres-sure to the wound with a compression dressing,compression bandage, or compression device

● Outcomes:

- Critical: Mortality due to bleeding; cessation of bleeding, achieving hemostasis; time to achieving hemostasis

-Important: Mortality from any cause; decrease in bleeding; complications/adverse effects(eg, wound infection, limb loss, rebleeding, pain related to an intervention)

● Time frame: November 1,2019, to November 2024

Summary of Evidence

Since the 2020 SysRev,5 articles199-203 were identified regarding the use of hemostatic dressings for the con-trol of life-threatening bleeding. While much of the data

<EndOfPara>continue to be indirect, data continue to suggest that hemostatic dressings decrease the duration of bleeding and improve survival when compared with conventional gauze used to stop life-threatening bleeding. There con-tinues to be a low reported rate of side effects. The new studies identified support the existing recommendations.Therefore, based on this EvUp, no additional ScopRev or SysRev is warranted.

Treatment Recommendations (2020)

We suggest that first aid providers use a hemostatic dressing with direct pressure as opposed to direct pressure alone for severe, life-threatening external bleeding (weak recommendation, very low-certainty evidence).

For the treatment of severe, life-threatening external bleeding by first aid providers, due to very limited data and very low confidence in effect estimates, we are unable to recommend the use of any one specific type of hemostatic dressing compared with another.

Duration of Cooling With Water for Thermal Burns(FA 7371, FA 770 SysRev 2021)

This topic was prioritized by the ILCOR FA Task Force because of a lack of international consensus about the optimal duration for cooling of thermal burns with run-ning water in the first aid setting and because of newly identified relevant studies since the topic was last re-viewed in 2015. A SysRev ${ }^{204}$ was undertaken on behalf of the FA and Pediatric Task Forces and was included in the 2021 CoSTR summary. ${ }^{161}$

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children in first aid settings with a thermal burn

• Intervention: Active cooling using running water for 20 minutes or more as an immediate first aid intervention

● Comparator: Active cooling using running water for any other duration as an immediate first aid intervention

● Outcome: Size of burn, defined as percentage of total body surface area at any reported time point;depth of burn, defined as any degree of deep partial or full thickness burn depth; pain, defined as any measurement of pain or administration of pain relief medications; adverse outcomes, defined as any adverse outcome, including hypothermia; wound healing, defined as time to re-epithelization in days;and complications within 24 hours, defined as organ dysfunction, ICU care, infections(within 7 days),bleeding, and rhabdomyolysis as well as the need for surgical procedures such as skin grafting, fasci-otomy, or escharotomy

● Time frame: All years to February 10,2021

Djarv et al

First Aid: 2025 CoSTR

Treatment Recommendations (2021)

We recommend the immediate active cooling of thermal burns using running water as a first aid intervention for adults and children (strong recommendation, very low-certainty evidence).

Because no difference in outcomes could be dem-onstrated with the different cooling durations studied, a specific duration of cooling cannot be recommended.

Young children with thermal burns being actively cooled with running water should be monitored for signs and/or symptoms of excessive body cooling (good prac-tice statement).

Dental Avulsion(FA 7361, FA 794, EvUp 2025)

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children in any setting(in-hospital or out-of-hospital) with an avulsed perma-nent tooth

● Intervention: Any storage media, container, or technique

● Comparator: Storage in whole milk or the patient's saliva

• Outcomes:

- Critical: Success of replantation and tooth sur-vival or viability

-Important: Color of the tooth, infection rate, mal-function(eating, speech) and pain

● Time frame:July 1,2019,and updated to December 2,2023

Summary of Evidence

Since the last SysRev205 in 2020, 3 studies ${ }^{206-208}$ were identified regarding the use of a storage medium, con-tainer, or technique for an avulsed permanent tooth. The evidence suggests that storage in a cooler tempera-ture favored viability of periodontal ligament fibroblasts for all storage media, except for Hanks' Balanced Salt Solution (a buffered salt solution). Propolis (a natural product made by bees by mixing resin, wax, and oils),cow's milk, and almond milk can be alternative storage mediums. Based on this EvUp, an updated SysRev is not warranted.

Treatment Recommendation (2020)

We suggest the use of Hanks' Balanced Salt Solution,propolis(0.04-2.5 mg per mL 0.4% ethanol), oral rehy-dration salt solutions including Riccetal(oral rehydration salt solutions containing sodium chloride, glucose, potas-sium chloride,citrate(or extruded rice)), or cling film com-pared with any form of cow's milk for temporary storage of an avulsed tooth that cannot be immediately replanted(weak recommendation, very low-certainty evidence). If none of the above choices are available, we suggest the use of cow's milk, any percent fat or form, compared with tap water, buttermilk, castor oil, turmeric extract, or saline

(sodium chloride) for temporary storage of an avulsed tooth(weak recommendation, very low-certainty evi-dence).

There is insufficient evidence to recommend for or against temporary storage of an avulsed tooth in saliva compared with alternative solutions.

There is insufficient evidence to recommend for or against temporary storage of an avulsed tooth in probi-otic media, epigallocatechen-3-gallate,Dentosafe box,or egg white compared with cow's milk.

- Critical: Reduction of pain and reduction of swelling/edema

-Important: Recovery time, range of motion,adverse effects

● Time frame:January 1,2020,to September 30,2024

Summary of Evidence

Since the SysRev ${ }^{209}$ in 2020, no new studies were identi-fied.

Treatment Recommendations (2019)

We suggest either application of a compression bandage or no application of a compression bandage for adults with an acute closed ankle joint injury(weak recommen-dation, very low-certainty evidence).

Due to a lack of identified evidence, we are unable to recommend for or against use of a compression bandage for closed joint injuries on other joints besides the ankle.

Preservation of Traumatic, Completely Amputated or Avulsed Body Parts (FA 7391,ScopRev 2025)

Rationale for Review

Complete amputation of extremities or digits is a physi-cally and emotionally traumatic experience that can lead to long-term disability and disfigurement. Globally,the incidence and prevalence of traumatic amputations reached 11.37 million and 552.45 million respectively in 2019. Nonfreezing cold storage of an ischemic ampu-tated limb or digit is essential to improve the potential for successful replantation and revascularization, par-ticularly when transport times are prolonged. Only 35%of patients with traumatic amputations present to the emergency department with properly preserved ampu-tated body parts, making it difficult for surgeons to offer

Summary of Evidence

This review^{212} identified 37 studies from 23 countries with various study designs: 23 case reports, ${}^{213-235}$ case series, ${}^{236,237}$ 2 experimental studies using animal mod-els, ${}^{238,239}$ 1 prospective observational study, ${}^{240}$ 6 retro-spective observational studies, ${}^{210,241-245}$ and 3 SysRevs with meta-analyses. ${}^{246-248}$

All studies included human subjects except for the 2 experimental studies. The experimental studies assessed replantation success following storage of amputated parts for between 21 and 24 hours at room temperature, 4℃ and minus 5°C. Case reports ${}^{213-235}$ and series described varying degrees of successful replantation with revas-cularization of completely amputated or avulsed body parts that, before hospital arrival, were cooled by differ-ent means or stored without cooling. Total ischemic time between amputation and replationation rangeded from 2 hours to 15 days. Successful replantation was reported in nearly all case reports and series with amputations involv-ing body parts without skeletal muscle (eg, digits) and in those cases with longer ischemic times when the part(s)were preserved with cold storage. ${ }^{215,219,228,234}$ Unsuccessful replantations were described in cases of prolonged(eg, up to 30 hours) ischemia without cooling or cleaning/soaking the part in water for 2 hours. The process described for cooling varied widely but often involved wrapping the part in moist gauze, placing it in a plastic bag and then placing the bag in another container with ice or an ice-water mix.A complete overview of characteristics and key findings from the case reports and series is presented in Table 2.

The observational studies assessed factors poten-tially associated with successful replantation and func-tional recovery, including the method of preservation of the amputated part prior to hospital arrival and the total ischemic time. Three cohort studies ${}^{240,243,244}$ reported an association between cold preservation for up to 6 hours and successful replantation of major upper extremity,although replantation of upper extremities was reported in a fourth study ${}^{245}$ to be successful after 7 to 13 hours without cold preservation but with limited functional out-comes. A complete overview of experimental and obser-vational studies with key findings is presented in Table 3.

Three SysRevs with meta-analysis(Table 4) assessed clinical outcomes for amputated parts preserved with cooling compared with no cooling of tissue, but in most cases failed to describe the actual method of cooling or other factors such as cold or warm ischemia times.$^{246-248}$

Care for amputated body parts was found in guide-lines from St. John Ambulance and from several National Societies of the International Federation of Red Cross and Red Crescent.249-251 The guidelines249-251 describe wrapping the amputated part in moist gauze and plac-ing it in a watertight container, which is then placed in another larger container with ice or a mixture of ice and water.

Task Force Insights

Following a traumatic amputation or avulsion, the pri-rity is to care for the patient, including control of life-threatening bleeding. However, care of the amputated or avulsed part is sometimes overlooked or delayed. Our ScopRev found that in 9 out of 23 case reports, there was a delay in retrieving the amputated part due to the part being lost, intentionally discarded, or intentionally withheld in a hostage situation(Table 2).

More distal amputated parts(such as digits) without skeletal muscle appear to tolerate longer periods of isch-emia without cold preservation(eg, up to 12 hours) while cold preservation appears to extend the tolerable isch-emic time before successful replantation to 24 or more hours. Observational studies of major upper extrem-ity amputations note successful replantation and func-tion when cold preservation techniques were used, with extension of time to replantation to 12 hours versus 6 hours without cold preservation.

Guidelines identified provide a reasonable approach to providing cold but nonfreezing storage of amputated or avulsed body parts. Wrapping the part in gauze or cloth is intended to prevent freezing of the tissue. Moistening the cloth with saline or water is intended to prevent des-iccation of exposed tissues. Some guidelines also sug-gest labeling the container holding the body part with the name of the person, time of injury, and time the ampu-tated part was placed in cold storage.

Most evidence identified in this review appears to support the prehospital cold storage of amputated or avulised body parts, when feasible, especially when

transport of the part to a replantation center may be delayed or take up to 6 hours. A SysRev of this topic is planned.

Good Practice Statements(2025)

Success in replantation is time dependent; complete-ly amputated and avulsed external body parts such as fingers, hands, arms, and legs should be retrieved and transported as soon as possible, preferably to the same health care facility as the injured person(good practice statement).

Replantation outcomes may be improved by cooling without freezing the amputated or avulsed part as soon as possible and throughout transportation to a health care facility. If feasible, this can be accomplished by wrapping the part in a moist clean cloth or gauze and sealing it in a watertight bag or container prior to cooling(good practice statement).

Task Force Knowledge Gaps

● The optimal techniques for the provision of cold storage for an amputated or avulsed body part in

First Aid: 2025 CoSTR

the first aid/out-of-hospital setting, including cool-ers and freezer packs,instant cold packs,cool water,battery-powered coolers,and their association with successful replantation

● Systematic collection and reporting of data on the methods of prehospital preservation by first aid provid-ers and prehospital professionals specifically should be performed by both clinicians and researchers.

Exertion-Related Dehydration and Rehydration(FA 7241, FA 584, SysRev 2021)

During prolonged exercise, sweat losses generally ex-ceed fluid intake, and even low levels of dehydration can lead to impaired physical and cognitive performance. In such situations, it is of utmost importance to promote postexercise drinking to restore fluid balance,252 yet there is no clear endorsement regarding the specific type of rehydrating fluid. Therefore, a SysRev253,254 was under-taken on behalf of the FA Task Force and was included in the 2021 CoSTR summary.161

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Adults and children with exertion-related dehydration

● Intervention: Drinking oral carbohydrate-electrolyte or alternative rehydrating liquids

● Comparator: Drinking water

● Outcomes: Volume/hydration status(measured as cumulative urine volume, net fluid balance, hemato-crit, hemoglobin, plasma volume change), vital signs(measured as heart rate), development of hypona-tremia(measured as serum sodium concentration,serum/plasma osmolarity), need for advanced medi-cal care, and patient satisfaction(measured as thirst performance, perceived intensity of stomach fullness,nausea, stomach upset, abdominal discomfort)

● Time frame: All years to February 21,2021

Treatment Recommendations (2021)

We recommend the use of any readily available rehydra-tion drink or water for treating exertion-related dehydra-tion in the first aid setting (good practice statement).

We suggest rehydration for exertion-related dehy-dration with a 4% to 9% carbohydrate-electrolyte drink.Alternative rehydration options include 0% to 3.9%carbohydrate-electrolyte drinks, water, coconut water, or skim or low-fat cow's milk(weak recommendation, very low-certainty evidence).

There is insufficient evidence to recommend for or against rehydration with beer(0%-5% alcohol).

METHODS OF TICK REMOVAL(FA 7231 SYSREV 2021)

This topic was prioritized by the FA Task Force because of a lack of international consensus in guidelines for re-

<EndOfPara>moval of an attached tick in the first aid setting and a lack of prior SysRevs of this topic by ILCOR. This CoSTR was created with the adoption process255 by using a recent SysRev. Details of this review can be found in the 2021 CoSTR summary. ${ }^{161}$

Population, Intervention, Comparator, Outcome, and Time Frame

● Population: Individuals in the first aid setting with a tick attached to the skin

● Intervention: Any tick-removal method, including heat, chemical, commercial tick removal apparatus,or tweezers/forceps

● Comparator: Any other method of tick removal

● Outcome: Transmission of disease, removal of (parts of) the tick, damaged or broken-off mouth parts

● Time frame: 2017 (date of the adoloped SysRev) to February 14,2021

Treatment Recommendations (2021)

We recommend against the use of chemicals, heat, or ice in comparison with mechanical methods for the removal of a tick (strong recommendation, very low-certainty evi-dence).

We suggest either pulling with tweezers or using com-mercial devices according to the manufacturer's instruc-tions to remove a tick rather than removal by hand(weak recommendation, very low-certainty evidence).

Treatment of Jellyfish Stings(FA 7211, SysRev 2025)

Rationale for Review

This topic was prioritized by the FA Task Force based on the morbidity that jellyfish stings cause through-out the world. Jelly fish envenomation is common in coastal areas. While most jellyfish stings have local-ized effects only, stings by some species of jellyfish can cause systemic illness or death. In 2023, an updated Cochrane SysRev256 on interventions for the treatment of jelly fish stings was published, and an ILCOR sys-tematic reviewer was a member of the author team.That Cochrane review included randomized controlled trials only, and because of the very low certainty of the evidence, the authors concluded that the effectiveness of the treatments evaluated was uncertain. The FA Task Force undertook this review, ${ }^{257}$ including random-ized and nonrandomized research, to identify a broader range of evidence and help in the formulation of treat-ment recommendations. The full CoSTR can be found online. ${ }^{258}$

Consensus on Science

The 2023 Cochrane SysRev256 included 9 studies259-266 that were RCTs and quasi-RCTs. The current task force SysRev included the Cochrane data and identified 5 additional nonrandomized studies.267-271 Evidence from

all studies was of very low certainty and heterogenous,therefore no meta-analysis was possible. In the 2023 Cochrane SysRev,interventions were characterized into hot or cold treatments, topical treatments, and parenteral treatments. The overall evidence for all outcomes was of very low certainty and data were conflicting on the efficacy of heat and cold therapy. The RCT data sug-gested that heat(eg, hot water) may reduce pain when compared with cold after stings from Physalia. However,heat may not be superior to cold in reducing pain for the jellyfish Carybdea alata and Chironex flecker. Further, the RCT data did not find a significant difference in outcomes between different topical treatments(ie, application of seawater, fresh water, sting aid, Adolph's meat tenderizer,isopropyl alcohol, heated water, acetic acid, lidocaine, or sodium bicarbonate). The Cochrane authors concluded that because of the very low certainty of evidence, the effectiveness of any of the treatments evaluated in the review was uncertain. The Cochrane SysRev included a patient who sustained a first-degree burn following appli-cation of 10% ammonia.256 The Cochrane SysRev did not report any cases of increasing pain or redness of skin af-ter treatment with vinegar(5% acetic acid). This current task force SysRev identified 5 additional nonrandomized

However, heat may not reduce pain for the Carybdea alata and Chironex fleckeri(at 1 hour RR 1.16,95% CI 0.71-1.89; at 6 hours RR 1.66,95% CI 0.56-4.94; pain at the end of treatment RR 3.54,95% CI 0.82-15.31).

studies that reported the critical outcome of pain reduc-tion. Details of study findings are provided in Table 5.

In these studies, heat therapy provided benefit compared with ice pack therapy. Topical lidocaine also appeared beneficial compared with parenteral analge-sics and benzodiazepines.267-269 The use of seawater and topical lidocaine also provided pain relief and reduced erythema compared with no treatment.270,271 Faster pain relief and fewer areas of redness on skin were achieved with higher concentrations of topical lidocaine compared with benzocaine.270 In contrast, pain was increased by treatment with acetic acid, ethanol, or isopropanol com-pared with controls using sea salt water.271

Treatment Recommendations(2025)

Following a jellyfish sting, we recommend rinsing the area of the sting with seawater(strong recommendation,very low-certainty evidence).

For non-life-threatening jellyfish envenomation,we suggest the use of heated water(40-45℃[104-113°F](immersion, irrigation or shower) or hot pack application compared with application of a cold pack, topical lidocaine, benzocaine, acetic acid, Adolph's meat tenderizer, sting aid, or sodium bicarbonate to relieve pain from a jellyfish sting(weak recommendation,very low-certainty evidence).

We recommend against the use of topical 10% ammo-nia,isopropanol, or ethanol for the treatment of jellyfish stings(weak recommendation, low-certainty evidence).

Justification and Evidence-to-Decision Framework Highlights

The complete evidence-to-decision table is provided in Appendix A.

In making these recommendations, the FA Task Force considered the following:

Seawater should be available at the setting where envenomation occurs and requires no additional cost.Seawater should preferentially be used to wash the area to remove remaining tentacles or nematocysts that are stuck to the skin.

While hot water appears to demonstrate a bene-fit in the non-RCTs compared with other treatments,access to hot water may not be feasible in many parts of the world. Hot water may also lead to skin burns if the temperature is too hot. In some locations, solar-heated water bags and instant hot packs are available at beach lifeguard stations for treatment of jellyfish stings. Fresh water may activate nematocysts remain-ing on the skin,272 therefore, it is preferred to rinse the area of the sting with seawater prior to application of hot fresh water.

The included studies used a water temperature range of 40°C to 45°C(104-113°F); 1 study used hot packs that were reported to be 43°C(109°F),and 1 study used a“hot shower” without reporting the water temperature. It may be most practical to use water as warm as the person can safely and comfort-ably tolerate.

First Aid:2025 CoSTR

In the Cochrane SysRev,256 1 study showed that etha-nol resulted in increased pain following jellyfish stings compared with seawater while 2 other studies reported less reduction in pain with ethanol and isopropyl alcohol compared with seawater.

The efficacy of first aid treatment may depend on the species of jellyfish causing the envenomation and the benefit of heat therapy was evaluated in stings due to Physalia, Cyanea capillata, and Marine cnidaria. However,in many instances, it is not feasible for lay first aid provid-ers to know the type of jellyfish, resulting in the enven-oming before beginning.

Task Force Knowledge Gaps

● Whether the effect of jellyfish sting treatments dif-fers by species of jellyfish

● The effect of different jellyfish sting treatments on survival or need for hospitalization

May,228 1981, United States28-year-old male, amputation of 4 fingers of the left hand from a paper cutting machineDigits placed in plastic bag surrounded by iced saline (unclear if cooling occurred before arrival at hospital; patient presented with amputated parts soon after injury)Because of the time required to replant all digits, a cold isch-emia time of up to 28 hours was recorded for the final digit; all digits survived replantation; the case suggests that the margin of safety in digit replantation may be greater than previously thought
Musa,229 2016,Nigeria15-year-old male, avulsion of penis from a grinding machine, with scrotal laceration and devialized tissuesInitially resuscitation at local hospital; amputated penis wrapped in gauge at hospital and sent with patient to higher level of care, arrived 30 hours postinjury; no cooling of amputated tissuePatient presented 30 hours after injury with the penis mumimm -fied, precluding replantation

Szlosser,232 2015, Poland82-year-old male, transmetacarpal amputation of 4 fingers by circular sawAmputated fingers "cooled" and "stored appropriately" 3 hours prior to arrival at hospital2/4 amputated fingers were replanted, 4 hours warm isch-emia (operative) time; at 8 months, minimal movement of fin- gers; however, because the thumb was uninjured, hand grasp was preserved, and patient was satisfied with the result; age alone should not be an absolute contraindication to finger replantation
Usui, 233 1979, Japan14-year-old male, distal one third leg amputation from a mowerCooling of the amputated part in ice water; 5-hour transportation time to the hospitalSuccessful replantation, 5 hours cold ischemia time; at 4-year follow-up, no joint contracture or deformity; child able to walk and run as fast as other children his age; success was attributed to the patient's youth, ideal conditions for nerve repair, and the prearrival preservation of the amputated part in ice water
Wei,234 1988, Taiwan24-year-old female, amputations of 8 fingers by a paper cutting machinePrearival: All 8 digits wrapped in normal saline- soaked gauze and preserved in an ice bag; 76- hour transportation time to the hospitalAll replations were successful following 76-hour transport time with cold preservation and total cold ischemia times of 84, 86, and 94 hours for the left thumb, right thumb and left index finger; at 8 months post-op, the patient was able to per-form most routine household tasks
Berger,236 1977, Austria33 patients with 27 complete amputations, 41 incomplete ampu- tationsPrearival method of preservation or cooling not described except for 4 cases described as "improper first aid contributing to failed replant procedure," including: - Liquid-filled glass (1) - Floating in ice water (1) - No cooling (2)Functional replantation not achieved in 9 of 11 cases; warm ischemia time of more than 8 hours felt responsible for failure of replantation in 2 cases; review did not clearly describe the specific prearvalial method of preservation or cooling technique other than for 4 cases; cold ischemia times of up to 12 hours and a warm ischemia time of up to 6 hours considered the limit for replantation, although consideration of injury mechanism and storage technique were both necessary for exclusion of replantation
O'Brien,2378 patients, complete amputation of total 14 digitsThe amputated fingers were "cooled in ice" (n=3),"cooled by ice in a plastic bag" (n=4), and not reported (n=1)Of 14 digital amputations, 11 survived replantation (83%), with ischemia times of 7 to 14 hours; for preservation methods linked to replantation failures due to complications, one was "cooled in ice," one not reported

No difference among conventional methods of storage were noted if the amputated part is not frozen or allowed to become normothermic for more than 2 hours.
Li,242 2008, China211 patients(117 male and 94 female, mean age 26.2 years [range, 1-67 years]) with 211 complete fingertip am-putations undergoing replantation surgery1. Dry storage at room tem- perature(n=84 digits) 2. Dry storage at 2-6℃ (n=106 digits) 3. Immersed in saline or ethanol(n=21 digits)Compared with immersion in saline or ethanol, dry storage at room temperature was associated with increased survival rates in a nonstatistically significant man- ner(aOR,0.314;95% Cl,0.041-2.399; P=0264); compared with immersion in saline or ethanol, dry storage at 2-6 °C was significantly associated with increased survival(aOR,0.028;95% Cl,0.003-0.270;P=0.002); no statistical difference between room- and low- temperature(2-6°C) preservation, sug- gesting that the amputated fingertip could withstand longer warm ischemia timeBinary logistic regression analysis for predictor of digit survival found that injury mechanism, platelet count, preser- vation of amputated part before admis- sion, vein grafting, and smoking after the operation were independent prognostic variables that influence the survival of the replanted fingertip
Chen,241 2017, China896 amputated fingers (average patient age, 22.0±3.8 years)1. Freeze-dried (n=536) 2. Room temperature/dry (n=273) 3.

Okumus, ${}^{243}$ 2020,Turkey14 patients(14 male; mean age, 29.6 years; age range 11-45 years) with work- related amputations of an upper extremityAll amputated parts but one arrived at hospital "in prop-erly prepared cold ischemic conditions"; one without cooling had "appropriate" warm ischemic timeReplantation of amputated extremity in 11/14 cases (withheld in multilevel crush);“recommended ischemia times for reliable success with replantation are 12 hours of warm and 24 hours of cold ischemia for digits, and 6 hours of warm and 12 hours of cold ischemia for major replants; the amputated part should be wrapped in a saline-moistened gauze sponge and placed in a plastic bag; the plastic bag should be sealed and placed on ice; the amputated part should not be placed directly on ice"Overall satisfaction, recovery of active motion of digits and thumb opposition, wrist and elbow joints, recovery of sensitivity in the median and ulnar nerve distribution, and ability of the surviving hand or forearm to perform daily work were all judged satisfactory in hand replantations; some distal ulnar nerve motor function problems reported in 3 cases with replantation at the elbow
Tark,244 1989, Korea261 replantations of amputated digits and hands in 153 patients; 176 were complete amputations"Hypothermic" preservation (no description given of how "hypothermic preservation" was accomplished, and if performed before arrival to a hospital)Survival of replantated amputated parts was assessed based on a warm or cold ischemia time of ≤12 or ≥13 hours; there was no significant relationship between survival of the replant and length of isch-emic time in the cold ischemia amputated parts group; success rate of replantation within 12 hours of warm ischemia was higher than that after 13 hours of warm ischemia140 of 176 (80%) complete amputa- tions were successfully replanted; clean-cut proximal level amputations and hypothermic-preserved amputation parts had the highest survival rate; a higher survival rate seen with repair of both digital arteries and 2 veins rather than only 1
The Hoang, ${}^{245}$ 2009, Vietnam10 male patients with complete forearm amputations, ages 14 months-42 yearsNone of the amputated arms were "properly preserved"Ischemia times ranged from 7 to 13 hours; 1 illustrating case described the amputated arm wrapped in a towel, transported with the patient 3 hours to the hospital; no prehospital storage/ preservation of the amputated part was performed, beyond one case in which the arm was wrapped in a towelAll patients arrived at the hospital within 2-8 hours postinjury; none of the ampu-tated parts were properly stored; overall survival of replanted limbs was 100%; functional outcomes of replanted fore- arms at 20 months rated from"excel- lent" to“fair” in 70% of patients
Sinatro, ${}^{210}$ 2022, United States91 patients with trau- matic amputation and documented modality of preservation seen at a single tertiary centerPrearrival"proper preserva- tion" assessed, defined as "wrapping the part in saline soaked gauze inside a wa- tertight bag and placing it on ice"Most patients(60/91,65.9%) arrived most with proper preservation of their amputated parts; of 74 patients trans- ported by EMS, only 35.1% had proper preservation of their amputated part; only 25.5% of patients presenting from home had proper preservation of their amputated part(s)Replantation was attempted at a sig-nificantly lower rate(n=14, 23.3%) in patients with improperly preserved parts than in those with properly preserved parts(n=18, 58.1%)(P=0.001)
Waikakul, ${}^{240}$ 1998, Thailand186 patients(137 male,39 female; age range, 19-38 years) with upper limb amputations: 24 am-putations at the palm, 75 at the wrist, 50 at the forearm, and 28 through the upper arm and 9 disarticulations at the elbow"Good preservation" defined as "cooling" without further descriptionPrearival preservation by cooling of the amputated part showed a significant effect on the outcome and was a better predictor than ischemic timeThere were 167 successful replantations and 16 failed replantations; of 102 ampu- tated extremities that were cooled, 3 re- plantations failed; 99 were successful; for amputated parts with“poor” preservation, 13 replantations failed, and 68 were suc- cessful(P<0.05, X2 8.14); total ischemic time, sex and age did not affect results; the type and severity of injury were also good predictors of successful replantation and functional outcome at 2 years

Pain reduction (relief): criticalMcGee,268 2023Heat may reduce pain when compared to cold following stings from Physalia(at 1 hour RR 2.66,95% CI 1.71-4.15; at 6 hours RR 2.25,95% CI 1.42-3.56; at the end of treatment RR 1.63,95% CI 0.81-3.27). However, heat may not reduce pain for the Carybdea alata and Chironex fleckeri(at 1 hour RR 1.16,95% CI 0.71-1.89; at 6 hours RR 1.66,95% CI 0.56-4.94; pain at the end of treatment RR 3.54,95% CI 0.82-15.31). Topical application of seawater,fresh water, sting aid,Adolph's meat tenderzer,isopropyl alcohol, heated water, acetic acid, lidocaine, or sodium bicarbonate resulted in no significant difference in overall improvement between the different treatments.
Pain reduction (relief): criticalLopez,267 2000Hot water demonstrated a benefit in pain reduction as participants receiving hot water immersion (110°F) had a relative risk of 1.600 (95% CI, 0.9354-2.7367) for pain relief compared to those with ice pack therapy.
Pain reduction (relief): criticalKnudsen,268 2016Following treatment, VAS regarding pain for hot water immersion was 0.5 and for topical lidocaine 5% was 1.3 at 30 minutes (P<0.05).
Pain reduction (relief): criticalYoshimoto,269 2002An odds ratio of 11.5 (95% CI,1.007-131.28) was found regarding pain relief for heat therapy (hot shower, hot pack, hot wet compress) application versus parenteral analgesics. An odds ratio of 22.0 (95% CI, 1.40-378.90) was obtained for pain relief in heat application versus parenteral benzodiazepines.
Pain reduction (relief): criticalBirsa,270 2010Application of lidocaine concentrations of 10% and 15% produced immediate relief; 4% and 5% solutions pro-duced relief after approximately 1 minute, while 1,2, and 3% solutions required 10-20 minutes provide noticeable relief. Benzocaine provided some relief but took 10 or more minutes.
Pyo,271 2016Sea salt water and 10% lidocaine provided pain relief and less erythema in Nemopilema nomurai stings. Pain and erythema were increased by treatment with topical application of 4% acetic acid, ethanol(70%) and isopropanol compared with sea salt water. In Carybdea mora stings, seawater and 10% lidocaine reduced pain and erythema. Ethanol(70%) and isopropanol increased pain and erythema compared with sea salt water.
Adverse effects/ complications: importantMcGee,268 2023Ammonia treatment resulted in a first-degree burn in 1 participant.
Adverse effects/ complications: importantBirsa,270 2010Areas of redness were observed after treatment with benzocaine. More areas of skin redness were observed after treatment 5% acetic acid, or ethanol(70%) than in control (no treatment).
Adverse effects/ complications: importantPyo,271 2016Erythema developed with 4% acetic acid, ethanol(70%) and isopropanol following sting by Nemopilema nomurai. Erythema developed with ethanol(70%) and isopropanol following by Carybdea mura tentacles.
