Background Extracorporeal cardiopulmonary resuscitation (ECPR) introduced in the 1960s,allows clinicians to potentially rescue patients unresponsive to traditional cardiopulmonary resuscitation (CPR).Prolonged CPR rescue by extraeorporeal membrane oxygenation (ECMO) might provide an acceptable survival rate and outcome in survivors.The international consensus by the International Liaison Committee on Resuscitation (International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science with Treatment Recommendations in 2005; CoSTR 2005) has stated that ECPR might improve outcomes after cardiac arrest,compared with standard CPR,in cases of cardiogenic shock and witnessed arrest,where there is an underlying circulatory disease amenable to immediate corrective intervention.The American Heart Association (AHA) advocated that ECPR should be considered for inhospital patients following cardiac arrest as the duration of the noflow arrest is brief and the condition leading to cardiac arrest is reversible (e.g.,hypothermia or drug intoxication) or amenable to heart transplantation or revascularisation.Clinical and laboratory variables were demonstrated to predict survival to hospital discharge.We conducted this study to describe our experience using ECPR in resuscitating patients with refractory cardiac arrest in hospital and to describe extracorporeal membrane oxygenation (ECMO) weaning,hospital survival and outcomes after ECPR.
