Evaluation of Supraclavicular, Suprascapular, and Interscalene Nerve Blocks for Outpatient Shoulder Surgery

Not Applicable

Completed

• Conditions: Pain; Shoulder Joint; Pathologic Processes; Pain, Postoperative
• Interventions: Procedure: Brachial plexus nerve block

• Registration Number: NCT02287142
• Lead Sponsor: Benaroya Research Institute

Brief Summary

The aim of this study is to assess analgesic efficacy of a supraclavicular nerve block, suprascapular nerve block, or interscalene nerve block in a population undergoing shoulder arthroscopy with rotator cuff repair. The investigators hypothesize that subjects from all three arms will receive equal analgesia since these blocks are routinely performed to treat post-operative pain after shoulder surgery.
