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.
