摘要 目的:分析腰硬联合麻醉应用于剖宫产手术时,三种纵向体位对产妇血流动力学的影响。方法:择期剖宫产患者120例,ASAⅠ~Ⅱ级,无麻醉禁忌证或体位性低血压,随机分为3组,每组40例。A组头低足高15°,B组水平卧位,C组头高足低15°,麻醉前按5mL/kg预充输液,常规吸氧3L/min,然后施行腰硬联合麻醉,穿刺部位为L3/4,0.75%布比卡因1.4mL混合1.6mL脑脊液,推注时间30s,注药后按0.25mL/(kg·min)补液。观察注药前、注药后各个时间点的SBP、DBP、HR、SpO2、麻醉平面变化情况以及血压下降幅度>20%时麻黄素干预情况。结果:B组SBP、DBP下降及心率上升幅度比A、C组显著(P<0.05);B组需要麻黄素提升血压的频度比A、C组显著(P<0.01);B组无痛觉麻醉平面≥T4发生率较A、C组高,差异有显著性(P<0.05)。结论:剖宫产患者,采取头高足低或头低足高位并采用0.75%布比卡因1.4mL+1.6mL脑脊液这一种配方行腰硬联合麻醉,较水平卧位对血流动力学影响小。
