In-hospital resuscitation following unsuccessful prehospital advanced cardiac life support: 'heroic efforts' or an exercise in futility?

From our emergency department logbook we identified 281 consecutive patients transported to the Regional Medical Center at Memphis following failed prehospital advanced cardiac life support (ACLS). Medical records were obtained for 240 cases (85.4%). Initial cardiac rhythms in the ED included ventricular fibrillation or pulseless ventricular tachycardia (29%), electromechanical dissociation (18%), and asystole (51%). Thirty-two patients (13.3%) were successfully resuscitated in the ED, but only four (1.7%) survived to hospital discharge. Two patients had good neurologic outcomes; both degenerated to cardiac arrest shortly prior to arrival in the ED. The remaining two survivors were discharged to nursing homes with severe neurologic deficits. Of the 41 cases for whom no medical records could be found, 39 were noted in our logbook to have died in the ED. No record of subsequent hospital admission could be found for the other two. Both are presumed to have died. Failure to respond to prehospital ACLS predicts nonsurvival and may warrant cessation of efforts in the field. Future programs and research efforts in the management of out-of-hospital cardiac arrest should be focused on optimal provision of prehospital care prior to the onset of irreversible deterioration.
