摘要
目的 对比分析心脏停跳和不停跳心内直视下行瓣膜替换术的疗效。方法 ２３８例患者分别采用心脏停跳组和不停跳组两种手术方法。其中心脏停跳手术８８例，包括ＭＷＲ６０例，ＡＶＲ２例，ＤＶＲ２６例；不停跳手术１５０例，包括ＭＶＲ１０１例，ＡＶＲ１７例， ＤＶＲ３２例。不停跳组降温至 ３２± １℃并维持，仅阻断上下腔静脉，不阻断主动脉，余同停跳下手术。结果 不停跳组早期死亡２例（死亡率 １． ３３％），停跳组早期死亡 ４例（死亡率 ４． ５４％），其余均痊愈出院，随访 ３月～ ４年，恢复良好。结论 心脏不停跳心内直视手术，是一种有效的心肌保护方法，能减少并发症，缩短住院时间。
Objective:To compare the effects of valve replacement on beating heart and blood cardioplegic arrest.Methods:88 cases were ac- cept operation on arrest, and 150 cases were accept operation on beating heart. In beating heart group,only clamp the two venae cavae with keep- ing the perfusion of cannulation of aorta at 32± 1℃ of the body temperature.The methds of valve replacement were same the aorta cross- clamping in blood cardioplegic arrest group. Results:There were two patients surgical death (1. 33 % ) in beating heart group and four patients surgical death (4.54% ) in arrest group. The others were cured and followed - up for 3 -48months. The recovery were good.Conclusion:The open-heart op- eration on beating heart is a new good way for myocardial protection. It can reduce the complication and shorten the mean of hospital time than ar-rest group.
