Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Interscalene

Single-shot Interscalene Nerve Block with ropivacaine 0.5%

Group Type ACTIVE_COMPARATOR

Brachial plexus nerve block

Intervention Type 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.

Supraclavicular

Single-shot Supraclavicular Nerve Block with ropivacaine 0.5%

Group Type ACTIVE_COMPARATOR

Brachial plexus nerve block

Intervention Type 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.

Suprascapular

Single-shot Suprascapular Nerve Block with ropivacaine 0.5%

Group Type ACTIVE_COMPARATOR

Brachial plexus nerve block

Intervention Type 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.
