摘　　要：目的:探讨两种不同的麻醉方式对B超引导下臂丛神经阻滞的临床效果分析。方法:将92例肱骨及桡骨骨折患者分为传统组和B超组,各46例,均进行肌间沟臂丛神经阻滞麻醉,前一组采用盲探麻醉,后一组采用B超引导下麻醉,观察麻醉效果、神经阻滞指标及毒性反应的相关性。结果:B超组患者麻醉总有效率为95.65%,高于传统组的80.43%,差异有统计学意义(P<0.05);B超组患者阻滞起效时间快,镇痛时间长,麻醉剂使用剂量减少,与传统组相比,差异有统计学意义(P<0.05);B超组患者出现的毒性反应局部麻醉药物中毒及血肿等发生率为6.52%,少于传统组的21.74%,差异有统计学意义(P<0.05)。结论:B超引导下臂丛神经阻滞麻醉效果好于盲探操作麻醉方法,起效快,镇痛时间长,安全性高。Objective To investigate the clinical effects of two different anesthesia methods on B-ultrasound guided brachial plexus block.Method 92 patients with humerus and humeral fractures were divided into traditional group and B-group,46 cases in each group,all of which were anesthetized with intermuscular groove brachial plexus block.The former group was blinded with anesthesia,and the latter group was underwent B-ultrasound anesthesia.The correlation between anesthesia effect,nerve block index and toxicity was observed.Results The probability of excellent and good anesthesia in the B-mode group was 95.65%,which was higher than that in the traditional group and 80.43%(P<0.05).In the B-group,the onset time was fast and the analgesia was long.The dose reduction of anesthesia was compared with the traditional group(P<0.05).The incidence of local anesthetic poisoning and hematoma in the B group was 6.52%,which was less than the other group(21.74%)(P<0.05).Conclusion B-ultrasound guided brachial plexus block anesthesia is better than blind anesthesia,with quick onset,long analgesia and high safety.
