Efficacy of Different Medications as Adjuvants in Ultrasound-guided Supraclavicular Brachial Plexus Block in Forearm Surgeries

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.

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.

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.
