超声引导定位行肌间沟臂丛神经阻滞的麻醉效果

Ultrasound-guided Anesthesia Effect of Intermuscular Groove Brachial Plexus Block

目的探讨超声引导定位行肌间沟臂丛神经阻滞的麻醉效果。方法在医院2015年1月-2018年6月期间诊治的行臂丛神经阻滞患者中选取60例作研究对象,并按定位方式不同予以分组:对照组(n=30)采取传统解剖定位方式进行肌间沟臂丛神经阻滞麻醉,而研究组(n=30)采取超声引导定位方式进行麻醉,就2组患者的麻醉相关时间、麻醉阻滞效果以及围手术期间并发症发生率进行统计学分析。结果①研究组患者感觉阻滞起效时间、运动阻滞起效时间、麻醉起效时间均短于对照组(t=3.376、5.385、9.451,P<0.05);②研究组患者麻醉阻滞优良率93.33%高于对照组的70.00%(χ^2=5.455,P=0.020);③对照组并发症发生率是3.33%,与研究组的0.00%相比差异无统计学意义(χ^2=1.017,P=0.313)。结论超声引导定位行臂丛神经阻滞的麻醉效果确切,起效快,并能减少患者围术期并发症,值得借鉴。

Objective To investigate the anesthetic effect of ultrasound-guided localization of interscalene brachial plexus block. Methods A total of 60 patients with brachial plexus block treated in our hospital from January 2015 to June 2018 were selected and divided into two groups according to their location. The control group(n=30) was anesthetized by traditional anatomical location, while the research group(n=30) was anesthetized by ultrasound-guided location. And the anesthesia related time, anesthesia blocking effect and perioperative complications of the two groups were statistically analyzed. Results The onset time of sensory block, motor block and anesthesia in the study group were shorter than those in the control group(t=3.376, 5.385, 9.451, P=0.000). The excellent and good rate of anesthesia in the study group was 93.33%, which was higher than that in the control group(χ^2=5.455, P=0.020). And the incidence of complications in the control group was 3.33%, which was not statistically significant different from that in the study group(P<0.05)(χ^2=1.017, P=0.313). Conclusion Ultrasound-guided brachial plexus block has definite anesthetic effect, quick onset, and can reduce perioperative complications, which is worth learning.
