“…In the 2005 International Consensus Conference on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science,51 an important question was raised based on some recent evidence: whether to defibrillate first or to perform CPR first followed by defibrillation, particularly when more than 4–5 min has elapsed from collapse to rescuer intervention in victims with VF cardiac arrest. In animal studies, prolonged VF of more than 7 min was more effectively treated when 5 min of CPR was performed before defibrillation 52 53. In two human studies of out-of-hospital VF arrest, when the interval between the call to the EMS and delivery of the initial shock was 4–5 min or longer, a period of CPR before attempted defibrillation improved survival rates 11 12…”

Since its introduction more than four and half decades ago, the science of cardiopulmonary resuscitation has been enriched with a significant amount of scientific evidence. This in turn has led to the birth of new evidence based guidelines for resuscitation published by the European Resuscitation Council and the American Heart Association in late 2005. This article aims to review the recent advances and controversies in the science of resuscitation.

Countershock of prolonged ventricular fibrillation is usually followed by asystole or a nonperfusing rhythm. Data from three laboratory investigations indicate that administration of epinephrine and cardiopulmonary resuscitation (CPR) preceding countershock of prolonged ventricular fibrillation significantly improves cardiac resuscitation outcome compared with immediate countershock (relative risk reduction of failed resuscitation, 0.61). Preliminary investigations indicate that a similar improvement is not observed when the ventricular fibrillation period is of shorter duration, e.g., 5 mins. This time interval is probably at the lower limit at which CPR preceding shock of ventricular fibrillation provides benefit in terms of cardiac resuscitation. A single clinical trial of "CPR first" supports the use of a brief period of CPR before countershock of prolonged ventricular fibrillation. Additional trials with and without epinephrine are anticipated.
