周围神经刺激仪在臂丛神经阻滞中的应用

The application of the peripheral nerve stimulation in brachial plexus block

目的:比较神经刺激仪定位与传统异感法定位臂丛神经阻滞的麻醉效果。方法:选择上肢手术患者60例,ASAⅠ～Ⅱ级,随机分2组,每组30例。Ⅰ组采用神经刺激仪进行定位操作,以胸大肌、三角肌、肱二头肌收缩反应其中之一出现作为穿刺针正确定位标志;Ⅱ组采用传统找异感法进行臂丛神经阻滞,阻滞药用0.25%罗哌卡因。观察并记录2组臂丛神经阻滞效果和并发症情况。结果:Ⅰ组臂丛神经阻滞效果优于Ⅱ组(P(0.05),而并发症低于Ⅱ组(P(0.05),差异均有统计学意义。结论:神经刺激仪引导定位行臂丛神经阻滞,显著提高麻醉效果,且减少麻醉并发症。

Objective： comparing nerve stimulation paresthesia location and orientation of traditional brachial plexus block anesthesia.Method：60 patients with upper extremity surgery,ASA LevelⅠ～Ⅱ,were randomly divided into 2 groups with 30 each.GroupⅠ was treated with a nerve stimulator to locate operations to pectoralis major,deltoid,biceps contraction of one of the correct positioning of the needle appears as a symbol;GroupⅡ using the traditional method to find different sense of brachial plexus block,block medical ropivacaine 0.25%.2 groups were observed and recorded the brachial plexus block effects and complications.Result：The fine brachial plexus block in GroupⅠ is higher than that of group Ⅱ（P0.05）,and the complications in Group Ⅰ were lower than that of group Ⅱ（P0.05）,the differences were statistically significant.Conclusion：The nerve stimulator guided brachial plexus block positioning line,significantly increased anesthetic effect,and reduced anesthetic complications.
