Favourable survival of in-hospital compared to out-of-hospital refractory cardiac arrest patients treated with extracorporeal membrane oxygenation: an Italian tertiary care centre experience

Objective: Extracorporeal membrane oxygenation (ECMO) support has been suggested to improve the survival rate in patients with refractory in- and out-of-hospital cardiac arrest (IHCA and OHCA). The aim of our study is to report our experience with ECMO in these patients. Design: Retrospective, single-centre, observational study. Patients: From January 2006 to February 2011 we studied 42 patients (31 males) with refractory cardiac arrest. Measurement and main results: ECMO implantation was successful in 38 (90%) of the 42 patients. ECMO support was positioned: three times (8%) in the operating room, six (16%) in the cardiac surgery intensive care unit, 21 (55%) in the emergency room, five (13%) in the catheterisation laboratory and three (8%) in the general ward. A total of 14 IHCA (58%) and three OHCA (16%) patients were weaned from ECMO (. p
