Brief Summary   This study aims to compare the efficacy and safety of Dexamethasone versus Dexmedetomidine when used as adjuvants with Bupivacaine, Lignocaine, and Adrenaline in ultrasound-guided supraclavicular brachial plexus block for upper limb surgeries. A randomized controlled trial design will be followed with 98 adult patients divided into two groups of 49 each. Group 1 will receive Dexamethasone, and Group 2 will receive Dexmedetomidine as adjuvants. The primary outcomes include onset and duration of sensory and motor block, and incidence of adverse drug reactions. Secondary outcomes include hemodynamic effects and pharmacological interactions. Patients will be monitored for complications such as bradycardia, hypotension, and nerve injury. Data will be analyzed using standard statistical methods to determine which adjuvant provides superior block characteristics and safety profile. This research will help optimize postoperative analgesia and enhance patient recovery.
