Objective To investigate the clinical effect and significance of continuous brachial plexus anesthesia for upper extremity surgery and postoperative analgesia. Methods 110 patients of upper limb surgery with ASA classification of Ⅰ-Ⅱ class were collected and randomly divided into control group of 55 cases and treatment group of 55 cases. Control group was given conventional brachial plexus anesthesia and the treatment group was given 22G arteriovenous stranded needle continuous brachial plexus anesthesia. The sensory and motor block onset and perfect the time, 10 skin area of motor and sensory blockade, adverse events, postoperative complications, analgesia and other indicators of patients in two groups were observed and recorded. Results The excellent rate of the control group and treatment group were 83.64% and 92.73%, the differences of two groups compared (P < 0.05) were statistically significant; the average dosage of treatment group was significantly less than the control group; ramsay score results which showed that the treatment group was significantly better than control group (P < 0.05) with statistically significant. Conclusion Continuous brachial plexus anesthesia applied to the upper extremity surgery has the advantages of simple, controllable, safe, less of the dose of drug plus, satisfaction of anesthetic effect, which is worthy of promotion.%目的 探讨连续臂丛麻醉应用于上肢手术与其术后镇痛临床效果及意义.方法 选取拟行上肢手术且ASA分级Ⅰ～Ⅱ级患者110例,随机分为对照组和治疗组各55例,对照组采用常规臂丛麻醉,治疗组采用22G动静脉留置针连续臂丛麻醉.观察并记录两组患者感觉、运动阻滞起效及完善时间、10个皮区运动和感觉阻滞情况、不良反应、术后并发症及镇痛情况等指标.结果 对照组和治疗组的优良率分别为83.64％和92.73％,两组比较,差异具有统计学意义(P＜0.05);治疗组平均加药量显著少于对照组,Ramsay评分显著优于对照组,差异均具有统计学意义(均P＜0.05).结论 连续臂丛麻醉应用于上肢手术具有操作简单、可控性强、安全性高、再次加药量少及麻醉效果满意等优点,值得临床推广.
