Background: The efficacy of regional anesthesia techniques continues to evolve with advancements in ultrasound guidance. This study investigated whether reducing the volume of local anesthetic in ultrasound-guided supraclavicular brachial plexus block could maintain clinical efficacy while potentially reducing complications. We compared two different volumes of 0.5% ropivacaine to determine the optimal volume forupper limb surgeries.
Methods: A prospective, randomized, double-blind study was conducted on seventy patients undergoing elective upper limb surgeries. Participants were randomly allocated into two groups: Group A (n=35) received 20 mL and Group B (n=35) received 30 mL of 0.5% ropivacaine. Primary outcomes included onset and duration of sensory and motor blockade. S
