Evaluating IM Epinephrine for Pediatric Cardiac Arrest

Official title: Pediatric Out-of-Hospital Cardiac Arrest Resuscitation: Evaluation of IM Epinephrine (The PRIME Trial)

Run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's · NCT05166343 · Data updated 2026-11-12

This study is testing if giving epinephrine through a shot in the muscle can help children who have a cardiac arrest outside of the hospital recover faster and have better outcomes compared to the usual methods.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 1 day to 17 years who are experiencing an out-of-hospital cardiac arrest and have received CPR from trained responders.

Probably not a fit

Patients who have suffered cardiac arrest due to obvious traumatic events will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This trial evaluates the use of intramuscular (IM) epinephrine in children experiencing out-of-hospital cardiac arrest (POHCA) through a pragmatic, two-arm, open-label design. It aims to determine if IM administration can provide a quicker and safer initial dose of epinephrine compared to traditional intravenous or intraosseous methods. The study will assess the impact of IM epinephrine on the time to return of spontaneous circulation (ROSC) and overall patient outcomes. This is the first trial to investigate the use of IM epinephrine specifically in the context of pediatric cardiac arrest.

Why it matters

Potential benefit: If successful, this approach could lead to improved survival rates and outcomes for children experiencing cardiac arrest outside of a hospital setting.

How similar studies have gone: While there is extensive literature on IM epinephrine use in other contexts, this specific application in pediatric cardiac arrest is novel and has not been previously tested.
