2、)。记录各组麻醉至手术开始的时间和手术的时间;观察各组麻醉阻滞效果、麻黄碱用量和硬膜外追加2%利多卡因情况;记录各组产妇在麻醉前、麻醉后仰卧、麻醉后5min、麻醉后t0rain、娩婴各时间点心率、血压的变化情况;记录产妇恶心、呕吐、低血压等情况。结果麻醉后5min及10min收缩压c组与A组比较,差异有统计学意义(P<0.05);娩婴时收缩压c组与A、B组比较,差异有统计学意义(P<0.05);麻醉后10min舒张压C组与A组比较,差异有统计学意义(P<0.05);麻黄碱用量c组低于A、B组,差异有统计学意义(P<0.05);低血压发生率A、B组高于c组,差异有统计学意义
3、(P<0.05);A、B两组各项指标比较,差异均无统计学意义。结论蛛网膜下腔给予罗哌卡因小剂量腰麻1.6ml(8mg)复合硬膜外追加2%盐酸利多卡因3ml,对剖宫产产妇循环功能影响最小,副作用发生率最低。关键词:罗哌卡因;腰硬联合麻醉;剖宫产;循环中圈分类号:R971.2文献标志码:Adoi:10.3969/j.issn.1671-3826.2012.O1.030文章编号:1671-3826(2012)01-0079-04Dose-dependenteffectsofRopivacaineonmaternalhemodynamicsincombinedwithspinal
