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

Outcome
Missed primary endpoint
Stopped: “Due to resource limitations and the lack of difference observed between study groups after the interim analysis, the study was halted prematurely.”
paper Analysis of the primary outcome showed a 72-hour cumulative geometric mean oral morphine equivalent consumption difference of 11.9 mg (95% CI -6.9 to 30.8) between groups. PMID 36261261 ↗
paper Interscalene brachial plexus blocks performed with bupivacaine alone did not demonstrate non-inferiority compared to a mixture of liposomal bupivacaine plus bupivacaine PMID 36261261 ↗
