摘要 目的分析剖宫产的产妇在硬膜外麻醉后应用小剂量去氧肾上腺素对其容量分布的影响。方法选取63例行硬膜外麻醉后剖宫产的产妇,随机分为去氧肾上腺组(实验组)32例,胶体输液组(对照组)31例。术中实验组输入胶体液及去氧肾上腺素,对照组输入胶体液。记录产妇在入室时(T1)、给药后10min(T2)及子宫剖开(T3)、胎儿取出时(T4)、取出后10min(T5),至手术结束(T6)产妇的血压变化及心率变化。测定两组产妇术中的血液中血红蛋白、红细胞积压变化,并记录产妇术中不良反应发生情况。结果两组产妇在子宫剖开(T3)、胎儿取出时(T4)的平均动脉压及心率差异有统计学意义(P<0.05),其他时间无统计学意义(P>0.05)。对其术中的血液中血红蛋白、红细胞压积比较组间差异明显,P<0.05。实验组产妇出现恶心2例,呕吐1例,对照组出现恶心1例,呕吐1例,胸闷3例。结论小剂量去氧肾上腺素对剖宫产的产妇有较好维持心率、血压稳定的作用。可以减少胶体对血液的稀释造成的过度扩容,应用安全性较高,副作用小,适合临床产妇应用。
