超声引导下臂丛神经阻滞麻醉在上肢手术中的麻醉效果

目的探讨超声引导下臂丛神经阻滞麻醉对上肢手术患者的麻醉效果。方法选取2018年2月至2019年2月河南省省立医院收治的86例拟行上肢手术的患者作为研究对象,并按照随机数表法将其随机分为观察组和对照组,每组43例,其中观察组患者予以超声引导下臂丛神经阻滞麻醉,对照组患者予以传统盲探臂丛神经阻滞麻醉,对比两组患者感觉神经阻滞起效时间、运动神经阻滞起效时间、感觉神经阻滞持续时间、运动神经阻滞持续时间及镇痛效果。结果观察组患者感觉神经阻滞起效时间及运动神经阻滞起效时间明显短于对照组,而感觉神经阻滞持续时间及运动神经阻滞持续时间明显长于对照组,差异具有统计学意义(t=4.232、8.694、5.081、4.689,P均=0.000);观察组患者镇痛效果明显优于对照组,差异具有统计学意义(Mann-Whitney U=740.500,Z=-2.033,P=0.042)。结论超声引导下臂丛神经阻滞麻醉可有效缩短上肢手术患者的麻醉起效时间,提高神经阻滞效果,具有重要的临床意义。

Anesthesia Effect of Ultrasound-guided Brachial Plexus Block on Patients Undergoing Upper Limb Surgery

Objective To investigate the anesthesia effect of ultrasound-guided brachial plexus block on patients undergoing upper limb surgery.Methods 86 patients,who were admitted to Henan Provincial Hospital from February2018 to February 2019 and underwent upper limb surgery,were selected as study subjects,and then divided,according to random number table,into an observation group(43 cases) and a control group(43 cases).Patients in the observation group were anesthetized with ultrasound-guided brachial plexus block,while patients in the control group were anesthetized with traditional blind brachial plexus block.The sensory nerve block onset time and motor nerve block onset time,sensory nerve block duration,motor nerve block duration and analgesic effect were compared between two groups.Results The sensory nerve block onset time and motor nerve block onset time in the observation group were significantly shorter than those in the control group.The sensory nerve block duration and motor nerve block duration in the observation group were significantly longer than those in the control group and the comparison showed statistically significant difference(t=4.232,8.694,5.081,4.689,all P=0.000);the analgesic effect in the observation group was significantly better than that in the control group and the comparison showed statistically significant difference(Mann-Whitney U=740.500,Z=-2.033,P=0.042).Conclusion Ultrasound-guided brachial plexus block can shorten the onset time of anesthesia and improve the effect of nerve block during upper limb surgery,it has great clinical significance.
