Refractory Cardiac Arrest Treated On Field By ECMO

Out-of-hospital cardiac arrest without resumption of spontaneous circulatory activity despite advanced medical resuscitation is considered refractory. Under certain well-defined conditions, today in many cities around the world and particularly in Paris, it benefits from resuscitation called ECPR (extracorporeal cardiopulmonary resuscitation). This technique consists of the installation of an extracorporeal membrane oxygenation (ECMO) device allowing organ perfusion while waiting for a resumption of cardiac activity. Since 2011, the Paris SAMU (SAMU 75) has set up a team capable of implementing ECPR for refractory out-of-hospital cardiac arrests. This team based within the SAMU of Paris at the Necker hospital (ECMO team) composed of an emergency doctor or anesthesiologist-resuscitator, a nurse anesthetist and an ambulance driver intervenes in Paris and its nearby region at the request of medical regulation. Given the growing development of this activity, it is essential to measure its effectiveness in real-life conditions. The study consists of establishing a prospective register over a period of 20 years of patients aged over 18 years, victims of refractory non-traumatic out-of-hospital cardiac arrest in the coverage area of the ECMO TEAM of the Paris SAMU. The 1-year survival rate of patients will be measured, the functional prognosis will be evaluated and a search for associated factors will be carried out. Patients' long-term cardiac function will be collected as well as the incidence of ECPR-related complications.
