Does bystander-initiated chest compressions-only result in better patient outcome than full cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest? Unexpected result from a post-hoc analysis of the DEFI 2005 Trial.

摘要

Definitive evidence is lacking on the survival impact of different cardiopulmonary resuscitation (CPR) techniques. Recent studies show that compressions-only CPR by bystanders may be beneficial, especially in the five first minutes of witnessed out-of-hospital cardiac arrest. In an update to the 2005 Guidelines recommendation, an AHA science advisory promoted compressions-only CPR for rescuers with insufficient training or confidence to perform CPR. We compared the outcome impact of bystander-initiated full CPR, compressions-only CPR, and no CPR in patients with ventricular fibrillation enrolled in the DEFI 2005 trial (Clinicaltrials.gov, NCT00139542).
