Single-shot nerve block with IV dexamethasone for rebound pain after shoulder surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

A randomized approach compares a single-shot interscalene brachial plexus block combined with intravenous dexamethasone to manage post-surgical shoulder pain. The study focuses on patients undergoing elective shoulder procedures and aims to see if the combination reduces rebound pain when the block wears off, potentially avoiding the need for a continuous catheter. Methods include standard anesthesia with MAC and monitoring, plus the IV steroid given at the time of block. Outcomes consider pain levels, analgesic use, and recovery parameters. The intervention is designed to be simpler and less technically demanding than continuous nerve block approaches.
