Buprenorphine, Clonidine, and Dexamethasone on Duration of Brachial Plexus Blocks for Upper Extremity Surgery

The goal of this clinical trial is to learn if there is a difference in morphine requirements in patients after upper extremity surgeries including shoulder arthroscopy. The main question it aims to answer is whether there is a difference between Interscalene brachial plexus blocks with the addition of buprenorphine, dexamethasone, and clonidine and the same block without the adjuvant.
