摘要: 目的: 分析体重在10 kg以下危重先天性心脏病小婴儿体外循环(ECC)方法。方法: 对临床106例体重在10 kg以下危重先天性心脏病小婴儿进行了ECC下的外科矫治术,ECC分为低温停跳组(Ⅰ)和常温不停跳组(Ⅱ);术中超滤组(Ⅲ)与非超滤组(Ⅳ)。结果: 与停跳组(Ⅰ)相比,不停跳组(Ⅱ)ECC时间明显缩短(P<0.05),温度显著提高(P<0.001),总液体量显著减少(P<0.05);与非超滤组(Ⅳ)比,超滤组(Ⅲ)血液稀释度显著减小(P<0.001),稀释后HCT显著提高(P<0.001),术后呼吸极辅助时间明显缩短(P<0.05),胸腔引流量显著减少(P<0.05)。结论: 小婴儿手术中减少ECC预充量,选择合适的转流方法,积极超滤可取得良好的效果。Abstract: Objective: Research of extracorporeal circulation of infant patients less than10kg body weight. Methods: 106 cases were divided to four groups.GroupⅠ（n=77）were performed ECC with moderate hypothermia,GroupⅡ（n=29） were performed ECC with normal thermia beating heart.GroupⅢ（n=67） were used ultrafiltration and GroupⅣ（n=39）were not used ultrafiltration during ECC. Results: total priming volume in groupⅡwas less than it in groupⅠ（P＜0.05）,ECC time in groupⅡwas shorter than it in groupⅠ（P＜0.05）.the intubation time in group Ⅲ was shorter than it in group Ⅳ（P＜0.05）,the volume of drainage in group Ⅲ was lower than it in group Ⅳ（P＜0.05）,the hemodilution in group Ⅲ was lower than it in group Ⅳ（P＜0.001）and HCT in group Ⅲ was higher than it in group Ⅳ（P＜0.001）. Conclusion: Low priming volume,selecting the best ECC method and using concentrator can get good results in infant patients.
