摘要 目的 探讨麻黄素肌注预防腰硬联合麻醉下剖宫产术低血压的效果及合适剂量。方法 选择ASAI-Ⅱ级足月妊娠,无妊高征产妇60例。随机分为四组,每组20例,Ⅰ组为对照组,实验组于脊麻前10分钟肌注麻黄素,Ⅱ组、Ⅲ组分别肌注麻黄素20mg、30mg。麻醉前输入晶体液500ml,腰麻用药为0.75%布比卡因,用量为9.75~11.25mg。记录SBP、HR、SPO_2等,测定麻醉平面,观察围术期的不良反应,记录新生儿Apgar评分。结果 最高阻滞平面(T_6-T_4)无差异(P>0.05),麻醉效果均达到手术要求,各组新生儿娩出时Apgar评分相似(P>0.05)。围术期出现严重低血压5分钟Ⅰ组、Ⅱ组分别约为30%、20%,Ⅲ组无;10分钟Ⅰ组为25%,Ⅱ组20%,Ⅲ组16%;15分钟Ⅰ组为25%,Ⅱ组和Ⅲ组无;伴有心率低于50次/min,Ⅰ组、Ⅱ组均有2例,Ⅲ组无,Ⅰ组、Ⅱ组恶心呕吐明显多于Ⅲ组。结论 脊麻前10分钟肌注麻黄素30mg可明显减少脊麻下剖宫产术低血压的发生率与低血压的程度。
