摘要 目的探讨不同的方法预防脊麻后剖宫产低血压并发症的临床分析。方法选择ASAⅠ~Ⅱ级的择期剖宫产病人150例,麻醉前均用平衡液10ml/kg/h维持,按预防药物不同分为三组:I组(50例):麻醉前快速输注万汶10ml/kg;Ⅱ组(50例):5mg/min的速度静脉泵注麻黄素2分钟,Ⅲ组(50例):以50μg/min的速度静脉泵注苯肾上腺素2分钟,所有产妇若出现低血压给予麻黄素10mg静脉注射,观察血压、心率、脉搏、记录低血压、恶心呕吐、呼吸困难和术后头痛等并发症的发生率及新生儿1 min和5 min的Apgar评分。结果 3组患者麻醉后15min收缩压、舒张压、心率较麻醉前均有显著性差异(t=2.231、2.225、2.301、2.333、2.215、2.333、2.301、2.325、2.335、P均<0.05);3组新生儿1 min和5minApgar评分无无显著性差异(P>0.05);Ⅲ组低血压5例(10.0%)明显低于Ⅰ组9例(15.0%)(x2=3.987,P<0.05)。结论麻醉前预扩容加苯肾上腺素注射对预防脊麻后剖宫产低血压并发症的方式有较好的作用。
