摘　　要：目的:探讨超声联合神经刺激仪引导坐骨神经及股神经阻滞在骨科手术中的应用。方法:选取2012年6月至2015年4月期间骨科收治的80例通过神经阻滞进行单侧下肢手术患者。将所有患者随机分为观察组和对照组,每组各40例。对照组采用神经刺激仪引导,观察组采用超声联合神经刺激仪引导。比较两组患者的阻滞成功率、感觉阻滞时间及术后视觉模拟评分(visual analogue score,VAS)。结果:与对照组进行比较,观察组患者具有更高的下肢神经阻滞成功率,且两组患者之间存在差异(P<0.05)。观察组患者的起效时间和持续时间优于对照组(P<0.05)。术后24h观察组患者的VAS评分优于对照组(P<0.05)。结论:超声联合神经刺激仪引导坐骨神经及股神经阻滞的成功率较高,且起效时间和持续时间较长,具有较高的临床应用价值。Objective： To explore the application of ultrasonography combined with nerve stimulator to guide sciatic nerve and femoral nerve block in orthopedic surgery. Methods ：80 patients undergoing unilateral lower limb surgery which was treated by nerve block in department of orthopedics from June 2012 to April 2015 were selected and randomly divided into observation group and control group, 40 cases in each group. The control group was guided by stimulating instrument, and the observation group was guided by ultrasound combined with nerve stimulator. The patients＇block success rate, sensory block time and visual analogue score （VAS） were compared after operation between the two groups. Results：Compared with the control group, the lower extremity nerve block success rate was significantly higher in the observation group, with the difference statistically siguificant （ P 〈 0.05 ）. The onset time and duration were significantly lower in the observation group, with difference statistically significant （ P 〈 0.05 ）. Postopera- tive 24h score of patients was significantly better in the observation group, and there was statistical difference （ P 〈 0.05 ）. Conclusion：Ultrasound combined with nerve stimulator will guide sciatic nerve and femoral nerve block with high success rate, and longer onset time and duration, which is of high clinical application value.
