Abstract
INTRODUCTION: Cardiac arrest is the major cause of sudden death in developed countries. Extracorporeal cardiopulmonary resuscitation (ECPR) employs extracorporeal membrane oxygenation (ECMO) in patients without return of spontaneous circulation (ROSC) by conventional cardiopulmonary resuscitation (CPR). Aim of the current study was to assess short- and long-term outcome in patients treated with ECPR in our tertiary center and to identify predictors of outcome. METHODS: We retrospectively collected data of all patients treated with ECPR at our institution from 2002 to 2013. Outcome was assessed according to patient records; good neurological outcome was defined as cerebral performance category 1 or 2. Quality of life data was collected using EQ-5 questionnaire. Uni- and multivariate analysis was applied to identify predictors of outcome. RESULTS: One-hundred and seventeen patients were included into the study. Weaning from ECMO was successful in 61 (52 %) patients. Thirty-day survival endpoint was achieved by 27 (23 %) patients. Good neurological outcome was present in 17 (15 %) patients. Multivariate analysis revealed baseline serum lactate as the strongest predictor of outcome, whereas age and out-of-hospital CPR did not predict outcome. The optimal lactate cut-off to discriminate outcome was determined at 4.6 mmol/l [HR 3.55 (2.29-5.49), p < 0.001, log-rank test]. CONCLUSION: ECPR represents a treatment option in patients without ROSC after conventional CPR rescuing 15 % of patients with good neurological outcome. Serum lactate may play a crucial role in patient selection for ECPR.
