摘要
为了尽量减轻心肌缺血/再灌注损伤,在临床上探讨不阻断心肌血流的前提下进行心内直视手术的方法。我院在浅低温(31～34℃)、体外循环不阻断主动脉、心脏空搏下进行二尖辩置换、三尖瓣成形、右室流出道疏通、房缺或室缺修补等手术66例。结果66例手术顺利,术后心功能恢复良好。无低心排和栓塞症状。仅6例出现—过性血红蛋白尿。术野显露不如常规方法,手术操作技术要求较高。由此可见,不阻断主动脉心脏空搏时心内直视手术能维持心肌有氧代谢,在一定范围内有推广应用价值。
The method of open heart operation on empty beating heart was put to use on clinical trial, in order to confirm its effect of reducing myocardial ischemia and reperfusion injury 66 eases with congenital heart diseases (60 of 66) and rhemathic disesas(3/66) were operated on by the method with slight hypothermia (31 -34 C ) ,cardiopulmonary bypass and empty beating without clamping aorta. As result,all cases were through operation succefully.postoperation uneventrully. Athough the field was not so clear and wide as that of the method of the heart arrest, it is clear enough for almost uncomplicated intracardiac performace. In summary, the method may be more effective to protect myocardium, and worth using in many kind of open heat operations.
