Liposomal Bupivacaine vs. Plain Bupivacaine with Dexamethasone for Rhomboid Intercostal Block in the Management of Postoperative Pain After Video-Assisted Thoracoscopic Surgery: A Randomized Non-inferiority Trial.

ABSTRACT:

Introduction

Effective and sustained postoperative analgesia is essential to enhance recovery after video-assisted thoracoscopic surgery (VATS). Liposomal bupivacaine, a multivesicular formulation enabling extended local anesthetic release, offers a mechanistic advantage over conventional agents. However, prior comparisons with adjuvant-enhanced regimens such as plain bupivacaine plus dexamethasone were confounded by pharmacological and dose inequivalence. This equivalence-dose randomized controlled trial evaluated whether liposomal bupivacaine provides non-inferior analgesia to the standard combination when administered via rhomboid intercostal block (RIB).

Methods

In this double-blind randomized controlled trial, 90 VATS patients were randomly assigned to receive either: a
