A Comparative Study of Dexamethasone versus Midazolam as Adjuvant to 0.5% Bupivacaine in Ultrasound-Guided Supraclavicular Brachial Plexus Block for Upper-Limb Surgeries.

Background: Ultrasound has been effective in using low volume of local anesthetics for supraclavicular block. Steroids have been shown to increase the duration of local anesthetics.

Aims And Objectives: In this study, we compare the efficacy of dexamethasone versus midazolam when added to bupivacaine in supraclavicular brachial plexus block for upper-limb surgeries with regard to the time of onset and duration of sensory and motor blockades, duration of analgesia, sedation, and hemodynamic parameters.
