Comparison of Supraclavicular Brachial Plexus Block Guided by PNS, USG and Combined Method

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.

Treatment and study plan

Peripheral Nerve Stimulator-Guided Supraclavicular Brachial Plexus Block

Procedure

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

Ultrasound-Guided Supraclavicular Brachial Plexus Block

Procedure

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

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

Procedure

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

Primary outcomes

  1. Success of supraclavicular brachial plexus block

    Time frame: Within 30 minutes after completion of the supraclavicular brachial plexus block

    Successful blockade of the brachial plexus resulting in adequate surgical anesthesia without the need for supplementary analgesia or conversion to another anesthetic technique

  2. Time required for performing supraclavicular brachial plexus block

    Time frame: During the supraclavicular brachial plexus block procedure

    Time from insertion of the block needle to its removal, measured in minutes.
