Comparison of Pulmonary Function and Efficacy of Different Nerve Block Catheters for Shoulder Surgery

Not Applicable

Completed

• Conditions: Post-Operative Pain
• Interventions: Procedure: Continuous Nerve Block

• Registration Number: NCT02117778
• Lead Sponsor: Benaroya Research Institute

Brief Summary

This study is designed to evaluate lung function and pain control of continuous supraclavicular versus suprascapular versus interscalene nerve catheters in subjects undergoing total shoulder replacement. The investigators hypothesize that all three groups would have similar pain control; the supraclavicular and suprascapular groups may have better lung function.
