Effect of ultrasound-guided interscalene brachial plexus block and nervre stimulator on operation around shoulder joints / 实用医学杂志

ABSTRACT

Objective To evaluate the effect of ultrasound-guided interscalene brachial plexus block and nerve stimulator on operation around shoulder joints. Methods Sixty cases of patients scheduled for operation around shouler joints were randomly divided into group A and B , with 30 cases in each group. Patients in group A underwent interscalend brachial plexus block guided by nerve stimulator with 0.5% ropivacaine and those in group B interscalend brachial plexus block guided by ultrasound and nerve stimulator with 0.5% ropivacaine 30 mL. The number of puncture, the effect of anesthesia and complication of anesthesia in both groups were recorded. Results The number of puncture of group B was less than that of group A (P﹤0.05) while the effect of anesthesia and the duration of anesthesia of group B were similar to those of group A (P﹥0.05). There was no serious complications in two groups. Conclusion With definite anesthesia effect and less pain , ultrasound-guided interscalene brachial plexus block and nerve stimulator is simple and safe for operation around shouler joints.
