Impact of Intracoronary Versus Intravenous Epinephrine Administration During Cardiac Arrest .

Lithuanian University of Health Sciences160 enrolled

Overview

In hospital cardiac arrest (IHCA) is a major challenge imposed on almost all health care systems worldwide. Despite significant progress in cardiopulmonary resuscitation in the past few years, outcomes remain relatively poor with an approximate 49 % survival rate. Epinephrine administration remains a cornerstone in the treatment of cardiac arrest. However, the preferred route of administration remains a matter of debate within the medical community . Various routes of administration, including intravenous, intramuscular, intraosseous and endotracheal routes have been studied. Initially, American guidelines for the treatment of cardiac arrest recommended injection of 0.5 mg of epinephrine directly into the right ventricle through the parasternal approach, aiming to achieve higher peak intracardiac concentrations and a more central effect, however the intravenous route remained preferable due to its feasibility and safety . To our knowledge, intra-coronary epinephrine administration for intraprocedural cardiac arrest has not been evaluated or compared with other routes of administration.

Interventions

The study will enroll acute myocardial infarction patients who suffered from a cardiac arrest in the cardiac catheterization laboratory during percutaneous intervention procedure. Cardiac Resuscitation was performed according to the European Resuscitation Council (ERC) Guidelines. The preferred route of epinephrine administration was through the central venous access (by internal jugular or subclavian vein). Thus, if available, it was the preferred method of medication delivery. However, in cases without central venous access, the route of epinephrine administration (peripheral intravenous or arterial intracoronary) during cardiac arrest was left to the treating physicians.

Outcomes

Primary Outcomes

ROSC (return of spontaneous circulation) between different routes of epinephrine administration.

Return of sinus rhythm or atrial fibrillation/flutter for more than 5 minutes (through ECG monitoring)

Time frame: Up to 24 hours

Secondary Outcomes

Survival to hospital discharge with favorable neurologic status (CPC score1-2)

Cerebral Performance Category (CPC) - a five point scale that ranges from good cerebral performance (1) to brain death (5), is often used and is commonly dichotomized into "good" (CPC 1-2) versus "poor" (CPC 3-5) outcome .

Time frame: Up to 30 days
