摘要
目的：探索心脏空搏下心内直视手术的方法。方法：４７例心脏病患者在不使用心脏停搏液于心脏跳动下手术。建立体外循环后，将上、下腔静脉回心血流引入氧合器，使心脏处于空搏状态，维持窦性心律，灌注流量为６０～１２０ ｍ ｌ·ｋｇ－ １ ·ｍ ｉｎ－ １。平均鼻咽温度维持在３４℃。结果：全组病例全部康复，未出现低心排、肾衰、心律失常及空气栓塞等并发症。结论：空搏下心内直视手术是一种可选择的手术方法。
Objective: To study the method of open heart surgery in empty and beating heart. Methods: Forty seven patients undergone open heart surgery in beating heart without application of cardioplegia. After cardiopulmonary bypass was instituted, the inferior and superior venae cavae blood was diverted into an extracorporeal circuit (oxygenator). Empty and beating heart of sinus rhythm was maintained. Perfusion flow rate was 60～120 ml·kg -1 ·min -1 . The average nasopharyngeal temperature was maintained at 34℃. Results: All patients recovered smoothly. There were no serious complications such as low heart output syndrome, renal function failure, disthythmias and gas embolism. Conclusion: Open heart surgery in empty and beating heart is an applicable method of cardiac operation.
