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.

Conditions

Pain, Postoperative; Pain; Shoulder Joint; Pathologic Processes

Outcome Measures

Primary Outcomes (1)

• Pain

  NRS Pain Scale

  Same day, 1 hour after arrival in the post-anesthesia care unit after surgery

Secondary Outcomes (3)

• Lung function

  Same day, 1 hour after arrival in the post-anesthesia care unit after surgery

• Sensory and Motor Function

  Same day, 1 hour after arrival in the post-anesthesia care unit after surgery

• Diaphragmatic excursion

  Same day, 1 hour after arrival in the post-anesthesia care unit after surgery

Study Arms (3)

Interscalene

ACTIVE COMPARATOR

Single-shot Interscalene Nerve Block with ropivacaine 0.5%

Procedure: Brachial plexus nerve block

Supraclavicular

ACTIVE COMPARATOR

Single-shot Supraclavicular Nerve Block with ropivacaine 0.5%

Procedure: Brachial plexus nerve block

Suprascapular

ACTIVE COMPARATOR

Single-shot Suprascapular Nerve Block with ropivacaine 0.5%

Procedure: Brachial plexus nerve block

Interventions

Brachial plexus nerve block PROCEDURE

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.

Interscalene; Supraclavicular; Suprascapular
