NCT04051099

Brief Summary

To compare efficacy and safety between bilateral superficial cervical plexus block combined with intravenous sedation (RA group) and general anesthesia (GA group) for thyroid and parathyroid operations. This study evaluates postoperative numerical pain score and systemic opioid requirement within 24 hours.
