BackgroundPerioperative cardiopulmonary arrests are uncommon and little is known about rates and predictors of in-hospital survival.MethodsUsing the Get With The Guidelines®-Resuscitation national in-hospital resuscitation registry, we identified all patients aged 18 yr or older who experienced an index, pulseless cardiac arrest in the operating room or within 24 h postoperatively. The primary outcome was survival to hospital discharge, and the secondary outcome was neurologically intact recovery among survivors. Multivariable logistic regression models using generalized estimating equation models were used to identify independent predictors of survival and neurologically intact survival.ResultsA total of 2,524 perioperative cardiopulmonary arrests were identified from 234 hospitals. The overall rate of survival to discharge was 31.7% (799/2,524), including 41.8% (254/608) for ventricular tachycardia and ventricular fibrillation, 30.5% (296/972) for asystole, and 26.4% (249/944) for pulseless electrical activity. Ventricular fibrillation and pulseless ventricular tachycardia were independently associated with improved survival. Asystolic arrests occurring in the operating room and postanesthesia care unit were associated with improved survival when compared to other perioperative locations. Among patients with neurological status assessment at discharge, the rate of neurologically intact survival was 64.0% (473/739). Prearrest neurological status at admission, patient age, inadequate natural airway, prearrest ventilatory support, duration of event, and event location were significant predictors of neurological status at discharge.ConclusionAmong patients with a perioperative cardiac arrest, one in three survived to hospital discharge, and good neurological outcome was noted in two of three survivors.
