A Feasibility Randomized Control Comparison of Peripheral Interscalene Catheter to Liposomal Bupivacaine Single Injection for Interscalene Blocks Used in Pain Control for Total Shoulder Arthroplasties
Melinda Seering
Summary
Comparison of post-operative pain after total shoulder surgery. The Principle Investigator will be comparing Exparel single shot block to Interscalene catheter
Description
Regional anesthesia in the ambulatory surgery center venue has been shown to decrease unwanted side effects of anesthesia and improve patient satisfaction with their operative care. Total shoulder arthroscopy is noted to be a surgery that has high pain post-operatively. Patients generally utilize narcotics for up to two weeks post-operatively for pain control. Interscalene nerve blocks are widely utilized to help with better recovery and less post-operative opioid use. This may enhance patient satisfaction and make for fewer unwanted post-operative side effects from anesthesia such as nausea a…

Interventions
- ProcedureInterscalene Catheter
Pre-operatively the patient will have a interscalene catheter placed by a regional skilled anesthesiologist. The initial block will be with 20 cc of 0.5% Bupivacaine and maintained on an infusion post-operatively at 8cc/hr of 0.2% ropivacaine as is our intuitions protocol
- ProcedureExparel Single Shot Interscalene Block
Pre-operatively the patient will have a interscalene single shot block with 133 mg Liposomal Bupivacaine and 10 ccs 0.5% Bupivacaine placed by a regional skilled anesthesiologist.
