Single Shot Interscalene Block with Liposomal Bupivacaine versus Non-Liposomal Bupivacaine in Shoulder Arthroplasty

Regional anesthesia is a valuable component of multimodal pain control in total shoulder arthroplasty (TSA), and multiple interscalene block anesthetic options exist, including non-liposomal interscalene bupivacaine (NLIB) and liposomal interscalene bupivacaine (LIB). The purpose of the current of study was to compare pain control and opioid consumption within 48 hours postoperative in those undergoing TSA with either LIB or NLIB.
