心脏术后急性心功能不全VA-ECMO支持

VA-ECMO support for acute cardiac dysfunction after cardiac surgery

静脉-动脉体外膜肺氧合(VA-ECMO)以其有效的容量转换可以快速建立高效的心肺支持,其在心脏手术后因各种原因引起的严重急性心功能不全治疗中的应用越来越多。作为高效的体外生命支持治疗,VA-ECMO的建立、抗凝、撤除等患者管理依然是临床治疗中的棘手问题。心脏术后患者的特殊性决定了此类患者的VA-ECMO管理难度更大,需要规范系统地认识和掌握VA-ECMO才有利于提高此类患者的生存率。

Venoarterial extracorporeal membrane oxygenation(VA-ECMO)is a quickly initiated and highly valuable heart-lung supporting treatment based on its effective blood transferring from venous to arterial vessels.VA-ECMO is more and more used in the treatment of severe acute cardiac dysfunction caused by various reasons after cardiac surgery.As a highly effective extracorporeal life support therapy,the initiation of VA-ECMO,anticoagulation,weaning of VA-ECMO and other patient managements are still tough problems in clinical treatment.The particularities of patients after cardiac surgery make the management of VA-ECMO more difficult for such patients.It is necessary to systematically understand and master the norms of VA-ECMO in order to improve the survival rate of such patients.
