摘要目的探讨静脉预注和补救性静脉注射甲氧明对择期剖宫产腰-硬联合麻醉后低血压防治作用的临床疗效和安全性。方法 100例足月单胎妊娠拟行剖宫产产妇随机均分为:甲氧明静脉预注组(Ⅰ组),腰-硬联合麻醉,在腰麻药注入后,即刻静脉预注甲氧明2mg,如上述处理后仍出现低血压,再静注甲氧明1～2mg;无甲氧明预注组(Ⅱ组),剖宫产腰-硬联合麻醉标准治疗基础上,在腰麻药注入后,即刻不给予甲氧明及其它升压药物预注,患者麻醉后出现血压下降(下降>20%或SBP<90mmHg)静脉注射甲氧明2mg,如上述处理后仍出现低血压,再静注甲氧明1～2mg。记录腰麻前(T0),腰麻后5min(T1),10min(T2),15min(T3)和手术结束(T4)时HR,BP,以及两组新生儿脐动脉血气分析和1minApgar评分。记录两组低血压发生率,患者恶心呕吐等不良反应发生情况。结果 T1～T3时Ⅰ组SBP、DBP明显高于Ⅱ组(P<0.05),T0、T4时两组SBP、DBP和HR差异无统计学意义。术中Ⅰ组低血压及恶心呕吐等不良反应发生率明显低于Ⅱ组(P<0.05);两组新生儿1minApgar评分及新生儿脐动脉血气分析差异均无统计学意义。结论静脉预注甲氧明能有效降低剖宫产腰麻后低血压发生率,相对于补救性静脉注射甲氧明,其升高血压的效果更明显、稳定;两种方式防治产妇低血压对胎儿都比较安全。
