Effective Pain Management of Continuous Versus Single Shot Injection Interscalene Block During Shoulder Replacement Surgery
Shoulder replacement surgery is recognized as having the potential to cause a considerable
amount of postoperative pain. Adequate management of pain after surgery is necessary not only
to improve the patient's wellbeing but also to facilitate recovery. Several regional
anesthesia techniques are available to combat postoperative pain in the shoulder replacement
surgery patient, however, which method provides superior pain relief remains unknown. The
purpose of this study is to examine the effectiveness of a continuous interscalene block
versus a single shot interscalene block for postoperative pain relief in the shoulder
replacement patient.
Patients undergoing shoulder replacement surgery will experience more effective pain relief
with a continuous interscalene block versus and single shot interscalene block.

This is a prospective randomized controlled trial. 76 patients receiving either primary total
shoulder replacement, hemiarthroplasty, or reverse total shoulder replacement will be
randomized to a regional anesthesia technique as part of their surgical procedure. 38
patients will receive a single shot interscalene block containing ropivicaine and 38 patients
will receive a continuous interscalene block containing ropivicaine.
