Patients undergoing thyroidectomy frequently experience moderate postoperative pain that may require opioid analgesics. Opioid use is associated with adverse effects such as nausea, vomiting, respiratory depression, and delayed recovery. Ultrasound-guided regional anesthesia techniques may provide effective postoperative analgesia while reducing opioid consumption.
The aim of this prospective randomized study was to evaluate the analgesic efficacy of ultrasound-guided bilateral superficial cervical plexus block (BSCPB) in patients undergoing thyroidectomy under general anesthesia. Patients were divided into two groups: a block group receiving BSCPB with 0.5% bupivacaine and a control group receiving general anesthesia alone. Postoperative pain scores, opioid consumption, intraoperative analgesic requirements, and postoperative complications were compared between the groups.
