NCT01782872

Brief Summary

The purpose of this study is to determine which medication(s) should be included in the interscalene nerve block (an injection of local anesthetic \[numbing medicine\] near nerves in the shoulder) for patients undergoing total shoulder arthroplasty (shoulder replacement). The ideal nerve block would reduce pain after shoulder surgery without causing a great deal of muscle weakness.

Outcome Measures

Primary Outcomes (1)

  • Numeric Rating Scale (NRS) Pain Score With Movement

    Pain with movement at 24 hours from the nerve block (scale of 0-10; 0 = no pain, 10 = worst possible pain)

    24 hours after the interscalene block is given

Secondary Outcomes (3)

  • Duration of Analgesia From Interscalene Nerve Block

    Postoperative day 1 at 8AM & 5PM, postoperative day 2 at 8AM & 5PM

  • Numeric Rating Scale (NRS) Pain Scores at Rest

    Preop

  • Middle Deltoid

    24 hours after surgery
