OBJECTIVE: We investigated whether the survival of patients with inhospital cardiac arrest could be extended by extracorporeal cardiopulmonary resuscitation supported with extracorporeal membrane oxygenation compared with those of conventional cardiopulmonary resuscitation. DESIGN: : A retrospective, single-center, observational study. SETTING: A tertiary care university hospital. PATIENTS: We retrospectively analyzed a total of 406 adult patients with witnessed inhospital cardiac arrest receiving cardiopulmonary resuscitation for >10 mins from January 2003 to June 2009 (85 in the extracorporeal cardiopulmonary resuscitation group and 321 in the conventional cardiopulmonary resuscitation group). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The primary end point was a survival discharge with minimal neurologic impairment. Propensity score matching was used to balance the baseline characteristics and cardiopulmonary resuscitation variables that could potentially affect prognosis. In the matched population (n = 120), the survival discharge rate with minimal neurologic impairment in the extracorporeal cardiopulmonary resuscitation group was significantly higher than that in the conventional cardiopulmonary resuscitation group (odds ratio of mortality or significant neurologic deficit, 0.17; 95% confidence interval, 0.04-0.68; p = .012). In addition, there was a significant difference in the 6-month survival rates with minimal neurologic impairment (hazard ratio, 0.48; 95% confidence interval, 0.29-0.77; p = .003; p 10 mins after witnessed inhospital arrest, especially in cases with cardiac origins.
