Background and Objective: This study compared ultrasound-guided and peripheral nerve stimulator (PNS)-guided supraclavicular brachial plexus blocks for upper limb surgeries, evaluating block execution time, onset and duration of sensory and motor block, success rate, complications, and time to first analgesic request.

Methods: A prospective randomized trial was conducted on 80 adult patients undergoing elective upper limb surgery. After preoperative assessment and informed consent, patients were allocated into two groups—ultrasound-guided or PNS-guided blocks. Standard anesthesia protocols and continuous hemodynamic monitoring were followed. Key parameters, including onset, duration, success rate, and complications, were recorded.

Results: The ultrasound-guided technique showed faster onset, longer block duration, higher success rate, greater hemodynamic stability, and fewer complications compared to the PNS-guided approach.
