摘要
目的 回顾 15 5例体重在 5kg以下危重先天性心脏病婴儿体外循环 (CPB)方法。方法 对 15 5例体重在 5kg以下的危重先天性心脏病婴儿进行了CPB下的外科纠治术。年龄为 ( 3 .5± 2 .4)m ,体重为 ( 4.4± 0 .7)kg。其中 44例采用深低温停循环方法 ;7例采用深低温低流量方法 ;2 3例采用深低温停循环结合低流量方法 ;18例为中度低温转流方法 ;3 7例为浅低温转流 ;另外 18例是采用常温CPB方法。 5 2例采用改良超滤 (MUF)方法 ,4例进行常规超滤 (CUF)方法 ,90例运用常规超滤结合改良超滤方法。结果 CPB时间为 ( 75 .7± 41.5 )min ,主动脉阻断时间是 ( 48.9± 2 4.1)min,停循环时间为 ( 3 3 .9± 15 .1)min,低流量时间为 ( 62± 2 8.9)min。 90例采用CUF和MUF方法相结合 ,在转流期间CUF方法滤出液体 ( 2 5 1.2± 13 8.3 )ml。死亡 13例 ,死亡率 8.3 %。结论 采取减少预充量、合适的灌注流量和转流方法、超滤。
OBJECTIVE 155 infants, weight less than 5kg, with various congenital heart defects were operated on. METHODS The infants age were (3.5±2.4)months and the weights were (4.4±0.7)kg. The study included 44 with deep hypothermia circulatory arrest (DHCA), 7 with deep hypothermia low flow rate (DHLF), 23 with DHCA+DHLF, 37with moderate hypothermia bypass and another 18 underwent NCPB. RESULTS CPB times were (75.7±41.5)min, (48.9±424.1)min, and (33.9±15)min. Modified ultrafiltration (MUF) was used in all patients,MUF combined conventional ultrafiltration(CUF) was used in 39 patients. Water (251.2ml±138.8ml) was removed by UUF + MUF during CPB. 13 cases were dead and the motality rate was 8.3%.CONCLUSION Appropriate infant bypass, low prime volume, keeping the high Hct, adapted perfusion flow rate, selecting the best CPB method can got good results.
