摘要：

目的 比较传统解剖定位与超声引导定位在臂丛神经阻滞麻醉中的应用效果。方法 选取我院2016 年1 月至2016 年12 月收 治的需行上肢手术患者90 例，均采用臂丛神经阻滞麻醉，按照定位方式将其分为对照组（n=42，采用传统解剖定位法）与观 察组（n=48，采用超声引导定位法），比较两组麻醉效果。结果 观察组患者的麻醉完成时间、麻醉起效时间均明显短于对照 组，其麻醉维持时间明显长于对照组（P<0.05）。观察组患者的麻醉优良率与并发症总发生率分别为100.0%、6.3%，明显优于 对照组的83.3%、31.0%（P<0.05）。麻醉后，观察组舒张末期速度、阻力指数、血流量及搏动指数均明显优于对照组与治疗前（P<0.05）。结论 超声引导定位相较于传统解剖定位，在臂丛神经阻滞麻醉中效果更优，更具推广价值。

ABSTRACT: Objective To compare the effect of ultrasound-guided and traditional anatomic localization in brachial plexus block anesthesia. Methods Ninety patients with upper limb surgery enrolled in our hospital from January 2016 to December 2016 were treated with brachial plexus block anesthesia. Patients were divided into control group (n=42, using traditional anatomic localization method) and observation group (n=48, using ultrasound guided localization method) according to the different positioning methods. The anesthetic effects of the two groups were compared. Results The completion time and the onset time of anesthesia in the observation group were significantly shorter than those in the control group, and the anesthesia maintenance time was significantly longer than that in the control group (P<0.05). The excellent rate of anesthesia and total incidence rate of complications in the observation group were 100.0% and 6.3% respectively, which were significantly better than 83.3% and 31.0% in the control group (P<0.05). After anesthesia, the end-diastolic velocity, resistance index, blood flow volume and pulsatility index in the observation group were significantly better than those in the control group and before treatment (P<0.05). Conclusion Compared with traditional anatomic localization, the ultrasound-guided positioning has better effect in brachial plexus block anesthesia, which has higher popularization value.
