摘　　要：目的探讨10公斤以下先心病患儿的体外循环管理。方法33例低体重先心病患儿在体外循环下行外科矫治术。采用膜式氧合器,预充量520-730ml,心肌保护采用改良St.Thomas液。21例使用人工肾透析器改良超滤（MUF）。结果主动脉阻断时间（37.5±20.2）min,体外循环时间（64.4±26.3）min。转流过程平稳,全部顺利停机。结论低体重先心病患儿的体外循环管理应尽量减少预充,积极排出体内多余水分,重视心肌保护,良好的体外循环管理是确保体外循环成功的关键。Objective To summarize the experience of the cardiopulmonary bypass （CPB） management in infants weighted less than 10kg with congenital heart disease. Methods 33 cases were underwent open heart operation with cardiopulmonary bypass with membrane oxygenator and cardioplegia by reperfusion with modified St. Thomas solution. The primed volume were 520 to 730m1. 21 cases were used modified ultrafiltration after bypass. Results The CPB duration was 64.4±26.3rain and the ascending aorta blockage time was 37.5±20.2 rain. Conclude Improving the quality of CPB on infants is the key for CPB.
