Brachial Plexus Block with Liposomal Bupivacaine for Shoulder Surgery Improves Analgesia and Reduces Opioid Consumption: Results from a Multicenter, Randomized, Double-Blind, Controlled Trial.
Pain medicine (Malden, Mass.).2020;21(2):387-400.Study Summary
Brachial plexus blocks are commonly used in shoulder surgery to reduce patient discomfort and analgesic use. However, their true effectiveness compared to placebo has been debated. In this study, the authors randomized patients to an ultrasound guided liposomal bupivacaine brachial plexus block or placebo.

A single injection of 133mg of Bupivacaine was found to significantly improve pain scores, reduce opioid consumption, and increase the proportion of opioid-free patients.
