Overview
Brief Summary
This is a prospective, randomised, double-blinded comparative clinical trial evaluating the efficacy of ultrasound-guided supraclavicular brachial plexus block versus ultrasound-guided infraclavicular brachial plexus block in adult patients undergoing forearm surgeries. Fifty-eight patients aged 20 to 60 years with ASA physical status I or II will be enrolled and allocated to one of the two groups using computer-generated randomisation. Both groups will receive 20 mL of 0.5% ropivacaine as a single-shot injection under ultrasound guidance. The primary outcome measures are onset time and duration of sensory and motor block. Secondary outcomes include time to first request for rescue analgesia, total rescue analgesic requirement in the first 24 hours, postoperative pain scores, and block-related complications. Assessments will be conducted intraoperatively and up to 24 hours post-procedure.

Outcomes
Primary Outcomes
Onset time and duration of sensory and motor block assessed using pinprick test and Modified Bromage scale in the radial, median, and ulnar nerve distributions
Time Frame: Onset assessed every minute from completion of local anaesthetic injection until full block achieved intraoperatively; duration assessed at 30 minute intervals post-procedure until complete recovery, up to 24 hours after block
Secondary Outcomes
- Time to first request for rescue analgesia, requirement for rescue analgesia in the first 24 hours, Visual Analogue Scale pain scores, and incidence of block-related complications including vascular puncture, pneumothorax, or nerve injury(Pain scores recorded at 2, 4, 6, 12, and 24 hours postoperatively; rescue analgesia requirement monitored throughout the first 24 hours; complications noted intraoperatively and during the postoperative 24-hour observation period)
