Extracorporeal Life Support and Mechanical Circulatory Support in Out-of-Hospital Cardiac Arrest and Refractory Cardiogenic Shock.

The prevalence of extracorporeal cardiopulmonary resuscitation is increasing worldwide as more health care centers develop the necessary infrastructure, protocols, and technical expertise required to provide mobile extracorporeal life support with short notice. Strict adherence to patient selection guidelines in the setting of out-of-hospital cardiac arrest, as well as in-hospital cardiac arrest, allows for improved survival with neurologically favorable outcomes in a larger patient population. This review discusses the preferred approaches, cannulation techniques, and available support devices ideal for the various clinical situations encountered during the treatment of cardiac arrest and refractory cardiogenic shock.
