Outcomes in unsuccessful field resuscitation attempts

To determine the outcomes of patients who did not regain vital signs after prehospital advanced cardiac life support, we studied adult patients who sustained nontraumatic out-of-hospital cardiac arrest. Our study consisted of a 20-month retrospective review of 244 charts beginning January 1986. Twelve patients were excluded for drug overdose, family request, or unavailable data. Of the remaining 232 patients, 51 had a rhythm and pulse on arrival at the emergency department. The record of each of the remaining 181 patients was analyzed for age, sex, location, witness, CPR initiator, advanced life support unit response time, initial field rhythm, and initial ECG rhythm. Outcome alternatives were dead in emergency department or hospital admission. All hospitalized patients were further evaluated for survival to discharge and neurologic status at discharge. Ten of the 181 patients (6%) who failed prehospital resuscitation survived to hospitalization, and one (0.6%) was discharged neurologically intact. Survival to hospital admission did not correlate with any of the variables studied except gender. The one patient who survived a failed prehospital resuscitation was not endotracheally intubated in the field. Our data support the practice of pronouncing adult nontraumatic cardiac arrest victims who fail to respond to advanced cardiac life support efforts in the field as dead at the scene.
