摘　　要：目的:探讨超声引导下锁骨上臂丛神经阻滞麻醉中采用不同浓度罗哌卡因的麻醉效果。方法:选取2021年2月—2023年5月于六安市舒城县中医院接受超声引导下锁骨上臂丛神经阻滞麻醉的70例患者作为研究对象,采用随机数表法分为低浓度组(n=20)、中浓度组(n=30)、高浓度组(n=20)。低浓度组注射0.4%罗哌卡因,中浓度组注射0.5%罗哌卡因,高浓度组注射0.6%罗哌卡因。比较三组麻醉效果。结果:三组麻醉起效时间比较,高浓度组<中浓度组<低浓度组,差异有统计学意义(P<0.05)。三组镇痛维持时间比较,高浓度组>中浓度组>低浓度组,差异有统计学意义(P<0.05)。三组肌皮神经、桡神经、尺神经、正中神经感觉阻滞起效时间比较,差异无统计学意义(P>0.05)。三组感觉阻滞维持时间比较,中级度组、高浓度组长于低浓度组,差异有统计学意义(P<0.05)。低浓度组肌皮神经、桡神经、尺神经、正中神经运动阻滞起效时间长于中浓度组与高浓度,差异有统计学意义(P<0.05)。中浓度组、高浓度组运动阻滞维持时间长于低浓度组,差异有统计学意义(P<0.05)。三组不良反应总发生率比较,高浓度组>中浓度>低浓度组,差异有统计学意义(P<0.05)。结论:0.5%罗哌卡因在超声引导下锁骨上臂丛神经阻滞麻醉中的应用效果较好,起效较快,镇痛维持时间较长,感觉、运动阻滞时间长,不良反应发生率较低。Objective:To investigate the anesthetic effect of different concentrations of ropivacaine in ultrasound-guided supraclavicular brachial plexus block anesthesia.Methods:Seventy patients who underwent ultrasound-guided supraclavicular brachial plexus block anesthesia at Shucheng County Hospital of Traditional Chinese Medicine in Lu'an City from February 2021 to May 2023 were selected as the study subjects.According to random number table method,they were divided into a low concentration group(n=20),a moderate concentration group(n=30),and a high concentration group(n=20).The low concentration group was injected with 0.4%ropivacaine,the moderate concentration group was injected with 0.5%ropivacaine,and the high concentration group was injected with 0.6%ropivacaine.The anesthetic effects were compared among the three groups.Results:The onset time of anesthesia among the three groups was compared and ranked as follows:high concentration group<moderate concentration group<low concentration group,with a statistically significant difference(P<0.05).The maintenance time of analgesia among the three groups was compared and ranked as follows:high concentration group>moderate concentration group>low concentration group,with a statistically significant difference(P<0.05).There was no statistically significant difference in the onset time of sensory blockade of the musculocutaneous nerve,radial nerve,ulnar nerve,and median nerve among the three groups(P>0.05).The maintenance time of sensory blockade in the moderate concentration group and high concentration group was longer than that in the low concentration group,and the difference was statistically significant(P<0.05);The onset time of motor blockade of the musculocutaneous nerve,radial nerve,ulnar nerve,and median nerve in the low concentration group was longer than that in the moderate concentration group and high concentration group,and the difference was statistically significant(P<0.05).The maintenance time of motor blockade in the moderate and high concentration groups
