Abstract

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. A prospective database was retrospectively queried over a 4-year period. 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. Compared with CISB, LBB patients consume fewer opioids, have less pain, are discharged with less opioids, and have fewer revisits to the emergency department.
