摘要
在体外循环心内直视手术期间,血液有形成分大量破坏,激活的凝血和纤溶系统引起凝血功能异常,使得术后再次开胸止血的概率增加,导致患者机械通气和住院时间延长;大量的血液输注,可增加肾衰竭、脓毒症和心律失常的发生率,甚至导致患者死亡。而异体输血还会增加感染肝炎、艾滋病等传染病及其他并发症的机会,且近年来血源日趋紧张。所以,采取相关血液保护措施,在体外循环心内直视手术中显得日益重要。
In open heart surgery,the blood ingredients are extensively damaged,while activation of the coagulation and fibrinolytic systems cause coagulation abnormalities which increase the probability of secondtime thoracotomy to stop bleeding and the prolonged mechanical ventilation hospitalization time;big amount blood infusion increases the incidence of renal failure,sepsis and arrhythmia,and may even result in death in patients.The incidence of hepatitis,AIDS and other complications will be increasedby allogeneic blood transfusion,and a growing tension of the blood source is seen in recent years.Therefore,taking blood conservation measures has become increasingly important in open heart surgery.
