Abstract: Department of Anesthesiology, Lufeng People′s Hospital, Guangdong 516500, China. Objective To observe the safety and superiority of ultrasound-guided interscalene brachial plexus blockade in limb surgery and summarize experience. Methods Eighty patients with limb sur-gery were included in this study. Of them, 20 cases underwent surgical procedure by ultrasound-guided interscalene brachial plexus blockade way, while another 20 were treated with an anesthetic method by blind approach to brachial plexus block. The vital signs, effects of nerve block, complications between two groups were recorded and compared. Results The time of anesthesia initiation, the duration of anal-gesia and the success rate of the patients in the ultrasound-guided group were all superior to those of the blind brachial plexus block group, and the difference between the two groups was statistically significant （P<0.05）. The number of complications in blind approach-brachial plexus block group was higher than that in the ultrasound guided group, but the difference was not statistically significant（P>0.05）. There was no significant difference in the MAP, HR and RR between the two groups（P>0.05）. Conclusion Ultrasound-guided brachial plexus block can help to the anesthetic to the accurate position and improve the quality of anesthesia.
