Abstract 【Objective】To compare the application value between nerve stimulator positioning combined with ultrasound-guided and simple ultrasound-guided axillary brachial plexus block in anesthesia for patients undergoing lower elbow surgery. 【Methods】Sixty patients undergoing lower elbow surgery were selected as the study subjects and were divided into the observation group and the control group, with 30 cases in each. The control group was treated with ultrasound-guided axillary brachial plexus block while the observation group was treated with nerve stimulator positioning combined with ultrasound-guided axillary brachial plexus block. The operation time, onset time of block of relevant nerves, duration of nerve block, success rate of block within 0.5h and success rate of one-time puncture were observed and compared between the two groups. The incidence of related complications was recorded. 【Results】The total success rate of brachial plexus block within 0.5h in the observation group was significantly higher than that in the control group (100.0% vs 86.7%), while the incidence of related complications was significantly lower than that in the control group (6.7% vs 26.7%) (P< 0.05). The average operation time and block onset time of radial nerve, ulnar nerve, median nerve and musculocutaneous nerve of patients in the observation group were significantly shorter than those of control group, while the duration of nerve block was significantly longer than that of the control group (P<0.05). There was no significant difference in the success rate of one-time puncture between the two groups (P>0.05). 【Conclusion】The application of nerve stimulator combined with ultrasound-guided axillary brachial plexus block in patients undergoing lower elbow surgery can improve the accuracy of positioning and the success rate of axillary brachial plexus block. It has positive effects on reducing the risk of related complications and extending the duration of the nerve block.
