摘要 目的观察低浓度罗哌卡因腰麻-硬膜外联合阻滞在腰椎间盘摘除术中的应用效果。方法腰椎间盘突出症40例,分为腰麻-硬膜外联合组(观察组)和硬膜外麻醉组(对照组)各20例。观察组用0.1%罗哌卡因4 ml行腰麻后待翻身体位固定后再注入0.2%罗哌卡因5 ml于硬膜外,根据麻醉效果及平面分次硬膜外推注0.2%罗哌卡因10~15 ml,对照组用2%利多卡因3~5ml和0.75%罗哌卡因5~15 ml行连续硬膜外麻醉,观察对照两组起效时间、镇痛和肌肉松弛效果,术中、术毕患者脚、下肢活动情况及麻醉前后循环系统的变化。结果观察组麻醉起效时间明显快于对照组(P>0.05),镇痛和肌肉松弛效果两组差异不显著(P>0.05),术中、术毕患者脚、下肢活动情况明显优于对照组(P<0.05)。观察组麻醉后15、30 min血压及心率与麻醉前差异不显著(P>0.05),而对照组麻醉后15、30 min血压及心率较麻醉前显著下降(P<0.05)。结论低浓度罗哌卡因腰麻-硬膜外联合阻滞的起效时间、术中、术毕患者脚、下肢活动情况及麻醉前后的血流动力学稳定明显优于连续硬膜外麻醉。
