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

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

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.

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
