Randomized Controlled TrialInterscalene Block with and without Intraoperative Local Infiltration with Liposomal Bupivacaine in Shoulder Arthroplasty: A Randomized Controlled Trial.
Interscalene brachial plexus blockade (ISBPB) is an effective anesthetic technique for shoulder arthroplasty; however, "rebound pain" can increase the patient's postoperative pain experience and narcotic usage. Exparel (liposomal bupivacaine) injected into the soft tissues at the surgical site has theoretical efficacy for up to 72 hours after administration. The purpose of this study was to evaluate postoperative pain scores and narcotic consumption following shoulder arthroplasty performed with either ISBPB alone or ISBPB and intraoperative Exparel. ⋯ Therapeutic Level l.
