Effect of superficial cervical plexus nerve block with Ropivacaine or a combination of different adjuvants on perioperative analgesia and quality of postoperative recovery in patients undergoing radical thyroid cancer surgery under general anesthesia

Bilateral superficial cervical plexus nerve blocks with Ropivacaine or a combination of different adjuvants are superior to general anesthesia alone in terms of intraoperative hemodynamics, the amount of sedative and analgesic drugs, and analgesic efficacy and quality of recovery in patients undergoing radical thyroid cancer surgery with nerve monitoring without muscarinic maintenance. Ropivacaine combined with an adjuvant has better analgesic effectiveness and quality of recovery than without an adjuvant, and Ropivacaine combined with dexmedetomidine has a better sedation level than dexamethasone.
