Subomohyoid vs Costoclavicular Block in Shoulder Surgery

Postoperative pain is important following arthroscopic shoulder surgery. Postoperative effective pain treatment provides early mobilization and shorter hospital stay.Ultrasound (US)-guided brachial plexus blocks such as interscalen and supraclavicular block are usually performed. Interscalen brachial plexus block is one of the most preferred techniques among these.Anterior suprascapular nerve block (subomohyoid plane block), which provides superior trunk block, as described by Siegenthaler et al., has been used for analgesia in shoulder arthroscopies because it is far from the neck and phrenic nerve.Karmakar et al. described the costoclavicular nerve block, which provides blocking of the posterior, medial and lateral cords of the brachial plexus. It has been suggested as an alternative to postoperative analgesia in shoulder arthroscopies and compared with interscalene brachial plexus block.The aim of this study is to compare the post op analgesic efficacy of both nerve blocks in shoulder arthroscopic surgeries.
