    [摘要] 目的 探討高频超声引导定位在肌间沟臂丛神经阻滞麻醉中的临床应用价值。 方法 依据麻醉时定位方式的不同，将2015年10月～2016年10月在西安医学院附属宝鸡医院接受肌间沟臂丛神经阻滞麻醉的112例患者分为A、B、C三组。A组46例采用传统解剖定位；B组30例采用神经刺激仪辅助定位；C组36例采用高频超声引导定位。比较三组患者麻醉完成时间、阻滞起效时间、镇痛维持时间、麻醉镇痛药物使用剂量、麻醉效果等指标。 结果 A组麻醉完成时间显著短于B、C组(P 0.05)；C组阻滞起效时间显著短于A、B组(P 0.05)；C组镇痛维持时间显著长于A、B组(P 0.05)。C组利多卡因、罗哌卡因、芬太尼等局麻镇痛药物使用剂量显著少于A、B组(P 0.05)；C组麻醉效果评分显著高于A、B组(P 0.05)。 结论 超声引导下肌间沟臂丛神经阻滞麻醉起效快，麻醉维持时间长，麻醉镇痛药物使用剂量少，麻醉效果好，值得临床推广应用。

    [Abstract] Objective To evaluate the clinical application value of ultrasound-guided interscalene brachial plexus nerve block anesthesia. Methods 112 cases of patients underwent interscalene brachial plexus nerve block anesthesia in Baoji Hospital Affiliated to Xi'an Medical College from October 2015 to October 2016 were selected， and divided into group A， B， C， according to different anesthesia location methods. 46 cases in group A were given traditional anatomical localization； 30 cases in group B were given nerve stimulator assisted localization； 36 cases in group C were given high-frequency ultrasound-guided localization. The indicators of anesthesia completion time ......
