自制“弯弧钝针”在臂丛神经阻滞应用的临床研究

Clinical Research on the Application of "Homemade Curved Arc Blunt Needle" in the Muscle between the Brachiai Plexus Nerve Block

目的:探讨"弧度弯针法"辅助定位行臂丛神经阻滞的效果。方法:150例上肢手术的患者随机分为3组各50例,Ⅰ组弧度弯针法。Ⅱ组传统异感引导法,Ⅲ组神经刺激器辅助定位法。均用0.375%罗哌卡因行肌间沟臂丛阻滞。结果:Ⅰ组的麻醉效果优良率明显高于Ⅱ组,麻醉效果差的病例数显著少于Ⅱ组,血肿发生率和膈神经麻痹发生率明显少于Ⅱ组,Ⅰ组和Ⅲ组比较各观察指标无明显差异。结论:"弧度弯针法"辅助定位行臂丛阻滞比异感方法定位准确,阻滞成功率高。

Objective： To study the effect of ＂ curved arc needle＂ for auxiliary positioning on line brachial plexus block, Methods：To randomly separate 150 patients with upper extremity surgery into three groups, each with 50 eases. Group Ⅰ uses bending acupuncture. Group Ⅱ uses the traditional sense＇guiding method. Group Ⅲ uses nerve-stimulator-assisted targeting method. All apply with 0. 375% ropivacaine in muscle of the brachial plexus block. Results： The narcotic effect of Group Ⅰ was better significantly than Group Ⅱ. The number of the poor narcotic effect cases is significantly less than Group Ⅱ. The incidence of hematoma and phrenic nerve palsy was significantly less than Group Ⅱ. There was no significant difference between Group Ⅰ and Group HI in terms of various indicators. Conclusion： ＂Arc-bending＂ for auxiliary positioning on hne bracliial plexus block is more accurate than sense-guiding targeting. The success rate of block is higher.
