小儿心脏手术体外循环临床分析(附100例报告)

目的：总结小儿体外循环方法及转流经验，方法：回顾分析100例小儿体外循环的预充、转流、心肌保护及并发症。结果：体外循环时间为47－310min，主动脉阻断时间为7－130min，心脏自主复跳79例，电击复律21例，发生意外及故障11例，其中鱼精蛋白过敏反应死亡1例。结论：小儿体外循环采用中度血液衡释维持适宜的胶体渗透压非常重要，可减少术后并发症，转流过程维持有效灌注压对脏及其它脏器复苏及术后血流动力学平稳具有积极的影响。

CLINICAL USE OF CARDIOPULMONARY BYPASS IN PEDIATRIC PATIENTS--A REPORT OF 100 CASES

Objective:To Summarize the clinical use and experience of cardiopulmonary bypass(CPB)in pediatric patients.Methods:Data of CPB procedures and complications in 100 pediatric patients were analysed retrospectively.Results:The CPB time was 47 310 minutes and aortic clamping time was 7 130 min utes.Among the 100 patients, spontaneous defibrilation occurred in 79 cases,and 21 cases were given electric shock.Accidents and disturbance occurred in 11 cases in which there was one death caused by allergy of protamine sulfate.Conclusion:Cardiopulmonary bypass can be performed successfully under proper procedures.It is important that moderate hemodilution should be maintained with proper colloid osmotic pressure in CPB.Applying membrane oxygenator and ultrafilter selectively can decrease postoperative complications.Keeping effective perfusion pressure during CPB hase positive effects on the resuscitation of heart and other organs and the stabilization of hemodynamics after operation.
