Articaine Plus Dexmedetomidine in Supraclavicular Block

Articaine has emerged as a local anesthetic (LA) that produces sensory and motor blockade shorter than bupivacaine and lower in neurotoxicity than lidocaine. Studies have shown that adding dexmedetomidine to LA produces prolongation of sensory and motor bock duration. Early regain of motor power with adequate analgesia is needed in ambulatory surgery, for early start of physiotherapy. This study was designed to test efficacy of adding dexmedetomidine to articaine on the duration of sensory and motor block.
