Effects on Postoperative Pain of Liposomal Bupivacaine in Interscalene Blocks for Total Shoulder Arthroplasty Patients

Study overview

The purpose of this trial is to compare the difference in the proportion of patients with tolerable pain scores, VAS pain scores, quality of recovery and opioid use in milligram equivalents (at 24, 48, 72, 96 and 120 hours postoperatively) in patients undergoing shoulder arthroplasty who receive interscalene blocks with or without Liposomal Bupivacaine. This is a prospective randomized, double-blinded, controlled trial that will enroll 130 subjects undergoing total shoulder arthroplasty or reverse total shoulder arthroplasty. Participants who meet all eligibility criteria will be randomized in a 1:1 ratio to receive either 36 mL of 0.5% bupivacaine (PB group) or 10 mL of liposomal bupivacaine and 20 mL of 0.25 % bupivacaine and 6 mL of saline (LB group).

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
