摘要
目的：旨在探讨改良超滤技术在婴幼儿心内直视手术体外循环中的应用。方法：随机抽取40例先天性心脏病患儿,20例于体外循环停机后行改良超滤即超滤组,20例未行超滤即对照组。分别于体外循环结束、体外循环后15分钟、60分钟和120分钟测量心率、血压、左房压、中心静脉压和胸腔引流量及术后输血量。结果：未发现与改良超滤有关的并发症。超滤组在体外循环后60分钟和120分钟,平均动脉压分别为93.5±10.3mmHg和84.7±8.6mmHg,而对照组为64.2±9.1mmHg和68.7±11.3mmHg,前者体循环压力明显高于后者。同时发现改良超滤组病例在短期内迅速提高红细胞压积,术后输血量和胸腔引流量显著低于对照组。结论：改良超滤是一种能有效减轻机体水负荷,改善心肺功能,降低输血所带来的感染危险和早日拔除胸腔引流管的安全有效的方法。
Objective：To evaluate the efficacy of modified ultrafiltration in paediatric cardiopulmonary bypass. Methods：Forty children undergoing cardiac operations were randomized into modified ultrafiltration group （MUF n= 20） and control group（n= 20） without MUF. Heart rate,blood pressure, henatocrit ,transfusion repuirements and volume of chest drainage were measured and compared between the two groups. Results： There were no MUF--related complications. MUF significantly improved systolic arterial pressure（93.5 ±10.3mmHg versus control 64.2±9. 1 mmHg and 84.7±8.6mmHg versus control 68.7±11.3mmHg） at 60 minutes and 120 minutes after CPB . Postoperative transfusion volume of chest dranage were both significantly decreased in MUF group. Conclusion： Modified ultrafiltration after cardiopulmonary bypass is a safe and effective method on reducing the total tody water,increasing blood pressure,improving hemodynamics, decreasing transfusion requirement and leading to earlier chest tube removal.
