Clinical Trial Summary

Interscalene brachial plexus block is known as the gold standard for analgesia after shoulder surgery, but limits the use of ipsilateral phrenic nerve paralysis. Recently, interest in potential diaphragm-sparing alternative blocks has increased for patients undergoing shoulder surgery.Two of these blocks are upper trunk block (UTB) and costoclavicular brachial plexus (CCBPB) block. This randomized controlled trial will compare ultrasound-guided UTB and CCBPB in patients undergoing arthroscopic shoulder surgery. The main outcome is pain intensity score at 30 minutes after arrival in the post anesthesia care unit (PACU) as measured by a numerical rating scale (NRS) from 0 to 10. The investigators research hypothesis is that UTB and CCBPB will result in equivalent postoperative analgesia at 30 minutes in the PACU.
