Dexmedetomidine and Nalbuphine as Analgesic Adjuvants to Bupivacaine in Superficial Cervical Block.

While the patient is in the supine position, the head will be turned to the opposite side of the surgical incision, and a line extending from the mastoid process to the clavicular head of the sternomastoid muscle will be marked. Aseptic preparation of this area will be done, and then the block needle will be inserted at the midpoint of this line with injection of bupivacaine 0.25%, dexmedetomidine 1 μg/kg (precedex 100mcg/ml), and adrenaline 1:200,000 in a total volume of 10ml normal saline in the above, below, and middle directions subcutaneously, creating a sausage-shaped swelling. The sensory block will be assessed with ice chips in the dermatome corresponding to the block, which included the skin of the neck, upper chest, shoulder, and ear, until the completion of the sensory blockade.
