Comparison Between Interscalene and Combined Costoclavicular-suprascapular Blocks for Arthroscopic Shoulder Surgery

The patient lies supine with the head turned to the contralateral side to the block. Using a linear high-frequency ultrasound probe, the proximal suprascapular nerve is visualized before it turns toward the suprascapular notch. It is blocked using 5mL of bupivicaine 0.5%.

transverse ultrasound imaging of the medial infraclavicular fossa to identify the cords of the brachial plexus at the costoclavicular space (CCS) then inject 10ml bupivicaine 0.5%

The patient lies supine with the head turned to the contralateral side to the block. Using a linear high-frequency ultrasound probe, the interscalene groove is visualized along with the roots of the brachial plexus. The block is performed with 15mL of bupivacaine 0.5%.
