Abstract:
Objective To compare the clinical effect of ultrasound and nerve stimulator guidance for interscalene brachial plexus block. Methods Sixty patients scheduled for upper extremity surgery were randomly allocated into two groups to receive either nerve stimulator guidance (group N,30 cases) or ultrasound guidance (group U, 30 cases) for interscalene brachial plexus block. The time for completing the procedure, the onset time of sensory block and motor block, as well as success rate of the procedure were recorded. The requirement for fentanyl during surgery, pain related with procedure and incidence of other complications were also recorded. Results The success rate of the procedure was 100% in both groups.Longer time was needed for completing procedure in group U [(16±7)min] than that in group N [(11±5)min](P＜0.05). The onset time of sensory block was significantly shorter in group U [(13±9)min] than that in group N [(18±7)min] (P ＜ 0.05 ), while the onset time of motor block was similar between the two groups. Twelve patients in group N and 5 patients in group U complained pain related with procedure, which were significantly different (P＜0.01 ). Conclusion Interscalene brachial plexus block with ultrasound guidance has similar clinical effect and success rate compare with nerve stimulator guidance.
