Effect Observation of Ultrasound-guided Clavicular Brachial Plexus Block in Upper Limb Surgery / 中国药师

ABSTRACT

Objective: To observe the effect of ultrasound-guided clavicular brachial plexus block in upper limb surgery.Methods: Eighty patients undergoing upper limb surgery were enrolled and randomly divided into two groups ultrasound-guided clavicular brachial plexus block group (ultrasound guidance group, n=40) and nerve stimulator-assisted positioning of the supraclavicular brachial plexus block group (nerve stimulator group,n =40).The block effect, anesthesia effect, anesthesia completion time, nerve block onset time, nerve block duration and complication were compared and analyzed statistically between the groups.Results: The completed rate of block was 97.5%in the ultrasound guidance group, which was significantly higher than that in the nerve stimulator group (65.0%) (P<0.05);the uncompleted rate was significantly lower than that in the nerve stimulator group.The fine/excellent rate of anesthesia was 95.0% , which was significantly higher than that of the nerve stimulator group (75.0%, 30/40) (P<0.05);the complete time of anesthesia and nerve block onset time were significantly shorter than those in the nerve stimulator group (P<0.05);the duration of nerve block was significantly longer than that in the nerve stimulator group (P<0.05);the incidence of complications was 7.5%), which was significantly lower than that of the nerve stimulator group (37.5%, 15/40) (P<0.05).Conclusion: In upper limb surgery, ultrasound-guided nerve stimulator assisted positioning of clavicular brachial plexus block is better than nerve stimulator assisted positioning of clavicular brachial plexus block.
