Abstract Objective To investigate the effect of ultrasound-guided lower brachial plexus block anesthesia in upper limb surgery. Method 80 patients who underwent upper limb surgery were randomly divided into two groups,all underwent intermyogenic brachial plexus block anesthesia,the control group used traditional anatomical puncture positioning,and the observation group Using ultrasound-guided positioning,the two groups' anesthesia-related indicators,excellent anesthesia rate,intraoperative hemodynamics,and postoperative pain scores were compared between the two groups. Results The onset time of sensory block,the onset time of motor block,and the dose of anesthetic drugs in the observation group were less than those in the control group（P<0.05）;the excellent and good rate of anesthesia in the observation group was 97.50%,which was significantly higher than the control group’s 75.00%（P<0.05）;The MAP and HR of the observation group at the beginning of the operation,30min after the operation,and at the end of the operation were lower than those of the control group（P<0.05）,but the SpO2 levels of the two groups were equivalent（P>0.05）;the observation group was 6h after the operation The VAS pain scores at 12h and 24h were significantly lower than those of the control group（P<0.05）. Conclusion Ultrasound-guided intermuscular brachial plexus block has a significant effect in upper limb surgery.The block has a fast onset,stable intraoperative hemodynamics,and low postoperative pain score,which has positive clinical significance.
