Abstract
Upper limb surgeries frequently use the brachial plexus block for anesthetizing the limb. The conventional approach by eliciting paresthesia is a blind procedure that may have a higher failure rate and can cause damage to the nerves and nearby structures. Peripheral nerve stimulator and ultrasound techniques were introduced to aid in better localization of the nerve/plexus avoiding tissue damage. With excellent localization and increased safety margin, ultrasound has increased the success rate of supraclavicular brachial plexus block. The purpose of this study was to compare the effectiveness of a Peripheral nerve stimulator withUltrasound for giving Supraclavicular brachial plexus block. Following the acquisition of patient consent, a cohort of 120 individuals were recruited for participation in this prospective randomised study. These participants were subsequently divided into two groups, namely Group PNS and Group USG, in a random manner. The Supraclavicular brachial plexus block procedure was administered to both groups, with Group PNS receiving the treatment guided by a Peripheral nerve stimulator and Group USG receiving the treatment guided by Ultrasound. Both experimental groups were administered a solution consisting of 15 mL of Bupivacaine with a concentration of 0.5%, along with an additional 10 mL of Lignocaine containing Adrenaline at a concentration of 2% (1:200,000). The primary factors taken into account were the timing of the onset of sensory and motor block, the length of time that analgesia was maintained, instances of block failure and any complications that arose subsequent to the block. The average duration of block administration was 10.17±1.58 min in the group receiving ultrasound guidance (group‐US) and 10.67±2.58 min in the group receiving peripheral nerve stimulation (group PNS) (p = 0.57). Therefore, the difference in the time taken to administer the block between Group US and Group PNS was found to be statistically insignificant. The duration of sensory block in group‐US was found to be 10.12±1.14 hrs, while in group PNS it was 7.41±0.68 hrs (p<0.0001). The success rate of the block was 96.67% in the US group and 80% in the PNS group, demonstrating statistical significance (p<0.05). The study's findings indicate that the ultrasound guided supraclavicular brachial plexus block is superior to the peripheral nerve stimulator guided brachial plexus block in terms of efficiency, accuracy and safety. This is due to its shorter onset time and longer duration of sensory and motor block.
