Study ObjectiveTo determine who may benefit from prolonged resuscitation efforts after therapy by emergency medical services system (EMS) personnel has failed to restore vital signs.DesignRetrospective chart review.Type Of ParticipantsTwo hundred sixteen consecutive adult patients with out-of-hospital cardiac arrest who were admitted to the emergency department without vital signs.MethodsIdentification of prehospital resuscitation data, therapy in the ED, hospital course, and final outcome.ResultsThirty-nine patients (18.1%) were resuscitated successfully. The odds ratio of successful resuscitation in the ED for the patients with ventricular fibrillation at the scene versus those with asystole or electromechanical dissociation was 3.4 (95% confidence interval, 1.5, 7.9). All patients with asystole or electromechanical dissociation, either at the scene or in the ED, died (95% confidence interval, 0, 4.3).ConclusionProlonged resuscitation efforts in the ED for patients with asystole or electromechanical dissociation usually are futile after previous efforts by the EMS personnel have failed to restore vital signs. Transportation to the hospital may not be indicated. However, for patients with persistent ventricular fibrillation, transport is indicated.
