Clinical Trial 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.

Eligibility

Inclusion Criteria:

• Unilateral total shoulder arthroscopy for rotator cuff surgery ASA physical status I-III, >18 years old, Non-pregnant, Consent to participate in the study

Exclusion Criteria:

• Refusal to participate, < 18 years old, Chronic opioid use, Localized infection, Pregnancy or lactating, Pre-existing coagulopathy, Allergy to ultrasound gel or local anesthetics, Diaphragmatic dysfunction

Related Conditions & MeSH terms

• Pain
• Pain, Postoperative
• Pathologic Processes
• Shoulder Joint

Intervention

Procedure:
• Brachial 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.
