Studying Outcomes of Refractory Out-of-Hospital Cardiac Arrest Treated with ECMO by the Paris SAMU Team

What this Trial Is About

Out-of-hospital cardiac arrest that does not regain spontaneous circulation despite advanced medical resuscitation is called refractory cardiac arrest. This research evaluates extracorporeal cardiopulmonary resuscitation ECPR, a technique using an extracorporeal membrane oxygenation ECMO device to maintain organ perfusion while awaiting heart function recovery. Since 2011, the Paris SAMU has operated a specialized ECMO team for refractory cardiac arrests in Paris and surrounding areas, and this study aims to measure the real-life effectiveness of this approach over 20 years. The study involves patients aged over 18 who experience non-traumatic refractory cardiac arrest and receive or attempt ECMO treatment by the Paris SAMU ECMO team. Medical data will be collected prospectively for these patients during and after their hospital care, including intensive care unit stay and follow-up medical reports. The study focuses on long-term outcomes, including survival and cardiac function after ECMO treatment. Participants data will be followed for one year after care to assess survival rates, neurological recovery, quality of life, heart function measured by left ventricular ejection fraction, occurrence of major cardiovascular events, and complications related to ECPR. Data is gathered from hospital records and communications with attending physicians. This observational study lasts 20 years, providing extensive monitoring of patient outcomes after refractory cardiac arrest treated with ECMO.
