Summary

This study is to evaluate whether addition of dexmedetomidine, dexamethasone and magnesium sulfate as adjuvants to bupivacaine in supraclavicular Brachial Plexus Blockade (BPB) for pain management assessed by VAS score.

Detailed description

This is a randomized controlled study involving 105 participants divided into three groups to assess the efficacy of adding dexmedetomidine, dexamethasone, and magnesium sulfate as adjuvants to bupivacaine in supraclavicular brachial plexus blockade during upper limb surgeries. The primary outcome is the postoperative Visual Analog Scale (VAS) score. The secondary outcomes are assessment of onset and duration of the block, patient satisfaction, and adverse effects.

Conditions

• Upper Limb Surgery
• Brachial Plexus Blockade

Interventions

Type	Name	Description
PROCEDURE	Group A (DT): Dexmedetomidine group	The ultrasound probe is placed in the supraclavicular fossa in the transverse orientation parallel to the clavicle and aimed inferior toward the ipsilateral thorax. The brachial plexus and the subclavian artery are visualized. The first rib appears as a hyperechoic line with the lung pleura deeper to this bony border. Utilizing the in-plane approach, the needle is advanced from lateral to medial, aimed near the main neural cluster of the brachial plexus. After negative aspiration, local anesthetic, including 100 µg Dexmeditomidine and normal saline, with a total volume of 20 mL, is injected. Subsequently, smaller aliquots of local anesthetic are deposited near the surrounding satellite neural clusters.
PROCEDURE	Group B (MG): Magnesium group	The ultrasound probe is placed in the supraclavicular fossa in the transverse orientation parallel to the clavicle and aimed inferior toward the ipsilateral thorax. The brachial plexus and the subclavian artery are visualized. The first rib appears as a hyperechoic line with the lung pleura deeper to this bony border. Utilizing the in-plane approach, the needle is advanced from lateral to medial, aimed near the main neural cluster of the brachial plexus. After negative aspiration, local anesthetic, including 150 mg of magnesium sulfate and normal saline, with a total volume of 20 mL, is injected. Subsequently, smaller aliquots of local anesthetic are deposited near the surrounding satellite neural clusters.
PROCEDURE	Group C (DM): Dexamethasone group	The ultrasound probe is placed in the supraclavicular fossa in the transverse orientation parallel to the clavicle and aimed inferior toward the ipsilateral thorax. The brachial plexus and the subclavian artery are visualized. The first rib appears as a hyperechoic line with the lung pleura deeper to this bony border. Utilizing the in-plane approach, the needle is advanced from lateral to medial, aimed near the main neural cluster of the brachial plexus. After negative aspiration, local anesthetic, including 8 mg dexamethasone and normal saline, with a total volume of 20 mL, is injected. Subsequently, smaller aliquots of local anesthetic are deposited near the surrounding satellite neural clusters.
