Comparison of Supraclavicular Brachial Plexus Block Guided by PNS, USG and Combined Method

This randomized comparative study evaluated supraclavicular brachial plexus block using three techniques in patients undergoing elbow and below-elbow surgeries. A total of 75 patients were included and allocated into three groups: Group A received a peripheral nerve stimulator (PNS)-guided block, Group B received an ultrasound-guided (USG) block, and Group C received a combined USG and PNS-guided block. The three techniques were compared with respect to ease of administration, success rate and quality of block, including duration of analgesia.
