Epinephrine Dose: Optimal Versus Standard Evaluation Trial

Status Recruiting

Clinical Trial Summary

The objective of this randomized controlled trial is to evaluate the effectiveness of a low cumulative dose of epinephrine compared to a standard cumulative dose of epinephrine during resuscitation from ventricular fibrillation (VF) or ventricular tachycardia (VT) in adult out-of-hospital cardiac arrest (OHCA) patients.

Clinical Trial Description

This study is designed as a prospective, multicentre, single-blinded randomized controlled trial (RCT) where eligible OHCA patients are randomized to receive a low cumulative dose of epinephrine (low dose epinephrine, up to 2mg total) or a standard cumulative dose of epinephrine (standard dose epinephrine, up to 6mg total) in a 1:1 fashion. Eligible OHCA patients will be treated by emergency medical service (EMS) providers who will initiate cardiopulmonary resuscitation (CPR) and the delivery of defibrillation shocks per EMS treatment protocols. After one defibrillation and when feasible, EMS providers will establish peripheral intravenous (IV) access, and patients will be randomly allocated to 1 of the 2 study arms. Subsequent study drug doses will be administered every 3-5 minutes, based on current guidelines and paramedic protocols, during resuscitation until the first return of spontaneous circulation (ROSC) is achieved or if resuscitation has been terminated by the base hospital physician. Other medications (e.g. antiarrhythmics, magnesium, beta blockers) and interventions (e.g. intubation) may be interposed as required. Follow-up will take place using a combination of administrative databases (e.g. the Discharge Abstract Database and the National Ambulatory Care Reporting System) and telephone interviews. This RCT will evaluate a fundamental change in the treatment of OHCA. The investigators hypothesize that a low cumulative dose of epinephrine will improve patient survival to hospital discharge compared to a standard cumulative dose of epinephrine. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
