ObjectiveTo explore clinical effects of nerve stimulator guided interscalene brachial plexus block and axillary brachial plexus block. MethodsA total of 158 cases of brachial plexus block selective surgery were randomly divided into observation group and control group, 79 cases in each group. Guided by nerve stimulation, the observation group were given muscle sulcus and axillary 0.25% ropivacaine injection, with a dose of 15mL and 25mL respectively; Control group were given axillary multipoint injection with 0.25% ropivacaine,the total dose were 40mL,the block of musculocutaneous nerve, median nerve, radial nerve and ulnar nerve respectively. ResultsBrachial plexus block time, operation time of observation group were significantly shorter than that of control group, the first block success rate was lower than control group, both the differences were statistically significant between the two groups (P＜0.05) .There were no significant difference in the second block success rate and the analgesic time between the two groups(P＞0.05). There were no significant difference in the scores of nerve block and sensory nerve block between the two groups(P＞0.05). ConclusionThe effect of interscalene brachial plexus block and axillary brachial plexus block guided by nerve stimulator is better than that of axillary multipoint block.
