2、药，观察麻醉起效时间、麻醉持续时间、麻醉效果；新生儿Apgar评分及麻醉并发症。结果三组患者麻醉起效时间、麻醉最高阻滞平面差异无显著性（P0.05）。A组麻醉持续时间明显短于B组、C组，且三组麻醉效果有差异(P0.05）。硬膜外追加2%利多卡因者A组（65%）高于B组(20%）和C组(15%）差异有显著性（P0.05）。三组麻醉后5min血压低于麻醉前(P0.05），C组明显低于A组(P0.05）。其他各时间点血变化差异无显著性(P0.05）。三组间各时间点心率、血氧饱和度及新生儿Apgar评分差异无显著性。C
3、组的恶心呕吐、胸闷气短发生率高于A组和B组,差异有显著性(P0.05）。结论DOC格式论文，方便您的复制修改删减0.75%罗哌卡因12㎎在急诊剖宫产术腰麻-硬膜外联合阻滞时的有效剂量。【关键词】罗哌卡因布比卡因腰麻-硬膜外联和麻醉剖宫产【Abstract】ObjectiveTostudytheclinicaleffectandsafetyofhigh-concentrationropivacaineforcombinedspinal-epiduralanesthesiausedinemergencycaesar
