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.

Interventions

PROCEDUREBrachial plexus nerve block

All arms of the study comparing the three different blocks are receiving the same single injection bolus of ropivacaine 0.5% prior to surgery. We will then record and compare pain scores in PACU and opioid requirement.
