Brief summary

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.

Interventions

PROCEDUREPeripheral Nerve Stimulator-Guided Supraclavicular Brachial Plexus Block

Supraclavicular brachial plexus block performed using a peripheral nerve stimulator for nerve localization.

PROCEDUREUltrasound-Guided Supraclavicular Brachial Plexus Block

Supraclavicular brachial plexus block performed using ultrasound guidance for nerve localization.

PROCEDURECombined Ultrasound and Peripheral Nerve Stimulator-Guided Supraclavicular Brachial Plexus Block

Supraclavicular brachial plexus block performed using combined ultrasound and peripheral nerve stimulator guidance
