Single-shot liposomal bupivacaine interscalene block versus continuous interscalene catheter in total shoulder arthroplasty: Opioid administration, pain scores, and complications

INTRODUCTION: We sought to evaluate the efficacy and safety of the liposomal bupivacaine interscalene block (LBB) compared with continuous interscalene catheter block (CISB) in primary shoulder arthroplasty patients. METHODS: A prospective database was retrospectively queried over a 4-year period. RESULTS: LBB (n = 34) patients had lower opioid consumption and pain scores than CISB (n = 70), especially in opioid naïve patients. LBB patients were discharged with less opioids and had fewer revisits to the emergency department. CONCLUSION: Compared with CISB, LBB patients consume fewer opioids, have less pain, are discharged with less opioids, and have fewer revisits to the emergency department.
