Dose Response Study of Dexamethasone in Combination With Bupivacaine 0.25% — Dex Dose  

Post Surgical Pain Clinical Trial

Official title: Dose Response Study of Dexamethasone in Combination With Bupivacaine 0.25% in Ultrasound Guided Supraclavicular Brachial Plexus Nerve Block, a Randomized, Placebo Controlled Prospective Clinical Trial

Status Completed

Clinical Trial Summary

When used in conjunction with a local anesthetic, dexamethasone may prolong both the sensory and motor effects of high supraclavicular brachial plexus nerve block (SBP) in arthroscopic shoulder surgery. This study seeks to determine if there is a relationship between the duration of sensory and motor blockade in supraclavicular brachial plexus nerve blocks (SBP) when combined with increasing doses of dexamethasone.

Clinical Trial Description

The exact mechanism of dexamethasone on peripheral nerve block is unclear. The current theory is that the effect is not dose related, while only 4mg and 8mg doses were studied. Our hypothesis is that the dose differences at 1mg, 2mg, or 4mg, does not have significant effect on the duration of analgesia. Therefore, we are not considering any patients to receive suboptimal dosing of preservative free dexamethasone in this study. ;
