摘要 目的探讨向左推移子宫并左侧卧位在预防腰硬联合麻下行剖宫产术低血压的效果。方法选择ASAI-II级、在腰硬联合麻下行剖宫产术的患者120例,随机分成三组,每组40例。所有病人在蛛网膜下隙穿刺成功后根据体重大小在60-80s内缓慢注入0.75%布比卡因1.5-1.7ml,并向头端置入硬膜外导管固定好。A组硬膜外导管固定成功后选择15°左侧卧位,B组用手将子宫向左推离中线3-4cm并15°左侧卧位,C组为对照组,直接放平仰卧。A、B、C组尽量保持原有体位至胎儿取出。结果 A、B两组腰麻成功后5min、10min、15min、20min低血压发生率明显少于对照组(P<0.05);而B组低血压发生率又明显少于A组(P<0.05)。结论用手向左推移子宫并左侧卧位与单纯的左侧卧位相比更能有效预防剖宫产术腰硬联合麻后引起的低血压。
