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

Anterior cervical discectomy and fusion (ACDF) nowadays is considered a common procedure.postoperative pain can hinder recovery and prolong hospital stay. The superficial cervical plexus block (SCPB) is a safe and simple technique that had been found to allow good pain relief in neck surgeries. The main drawback of SCPB was short duration, so adjuvants as dexmedetomidine and opioids has been used to increase analgesic duration and decrease the use of opioids. The current study will compare the efficacy of dexmedetomidine and nalbuphine as adjuvants to bupivacaine in SCPB in anterior cervical fusion surgeries.
