Impact of Intracoronary Versus Intravenous Epinephrine Administration During Cardiac Arrest .

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.
