[摘要]目的 分析神经刺激仪在小兒坐骨+股神经阻滞下肢手术中应用的安全性及可行性。方法 选取2016年10月~2017年2月我院行单侧下肢手术的患儿82例,用随机数字表的方法分为实验组和对照组,每组41例。对照组患儿采用传统异感定位神经阻滞的方法,实验组采用神经刺激仪定位神经阻滞的方法,比较两组患儿阻滞操作时间、阻滞起效时间、阻滞完善时间及阻滞成功率。结果 实验组组阻滞操作时间[(5.1±2.3) min]、阻滞完善时间[(12.4±3.2) min],低于对照组的(8.8±2.5) min和(18.6±4.4) min,差异有统计学意义(P<0.05)。实验组阻滞起效时间[(4.6±1.4) min]和对照组[(5.3±1.8) min]相比,差异无统计学意义(P>0.05)。实验组患儿神经阻滞成功率(97.56%)高于对照组的82.92%,差异有统计学意义(P<0.05)。结论 神经刺激仪在小儿坐骨+股神经阻滞下肢手术中神经阻滞的效果明显好于传统的神经阻滞方法,且能减少术后并发症的发生,安全性和可靠性都有保障,值得推广。

[Abstract]Objective To analyze the safety and feasibility of the application of nerve stimulator in the lower limb operation of sciatic nerve and femoral nerve block in children.Methods 82 cases of children with unilateral lower limb surgery in our hospital from October 2016 to February 2017 were randomly divided into experimental group and control group,each group of 41 cases.The traditional method of nerve block was used in the control group,and the nerve block was used in the experimental group,according to random number table.The two groups of children′s operation time,working time,complete occlusion time and success rate of nerve block were compared.Results The operation time of the experimental group was (5.1±2.3) min,the time of was (12.4±3.2) min,less than those of the control group(8.8±2.5) min and (18.6±4.4) min,the differences were statistically significant(P<0.05).The onset time of the experimental group was (4.6±1.4) min and the control group was (5.3±1.8) min,the difference was not statistically significant (P>0.05).The success rate of nerve block in the experimental group was 97.56%,higher than 82.92% in the control group,the difference was statistically significant (P<0.05).Conclusion The nerve block effect of sciatic nerve stimulator in 82.92% pediatric lower extremity surgery+femoral nerve block is obviously better than the traditional methods,and can reduce the incidence of postoperative complications.

传统的神经阻滞属于一种盲目操作,在小儿患者中难以广泛应用,容易造成阻滞不全或是麻醉失败的现象[1],且小儿神经难以准确定位,容易造成神经损伤。邓福谋[2]的研究表明,神经刺激仪的发展和Stimuplex穿刺针的应用,大幅度提高了外周神经阻滞的成功率,缩短手术操作时间和减少术后并发症。为研究神经刺激仪在神经阻滞手术中的安全性和可行性,我院在神经刺激仪的引导下完成小儿坐骨+股神经阻滞下肢手术82例,取得较好疗效,现报道如下。
