Upper-limb surgeries can be performed under either general or regional anesthesia.However, regional anesthesia has the advantages of long-lasting pain relief & avoidance of airway instrumentation.Brachial plexus block is a very reliable method of regional anesthesia for the upper limb. It achieves ideal operating conditions by producing complete muscular relaxation and stable intraoperative hemodynamics.However,Local anesthetics alone have a shorter duration of postoperative analgesia. Hence,various adjuvants have been added to local anesthetics to achieve quick, dense, and prolonged block. This study assess and compare the efficacy of using 8 mg dexamethasone or 10 mg nalbuphine as adjuvants to local anesthetics mixture (Lidocaine 2% + bupivacaine 0.5% 1:1 mixture) in Ultrasound-guided supraclavicular brachial plexus block for upper limb surgeries below the level of the shoulder.
