Purpose: Thyroidectomy causes postoperative pain and patient discomfort. Bilateral superficial cervical plexus block is a regional anesthesia technique that can provide analgesia during and after surgery. This study aims to compare the effectiveness of ultrasound (US)-guided versus landmark (LM) technique for bilateral superficial cervical plexus block in thyroidectomy.
Patients and methods: Thirty-six patients undergoing thyroidectomy were divided into two groups randomly (n=18); either US-guided (US group) or LM technique (LM group) for bilateral superficial cervical plexus block. Patient-controlled analgesia was used to control postoperative pain. Intraoperative opioid rescue, postoperative visual analog scale (VAS) score and opioid consumption were measured.
Results: The number of patients who required intraoperative opioid rescue was significantly lower in the US group (p≤0.05). There was no significant difference in postoperative VAS score at 3 hours (p>0.05), but postoperative VAS score at 6 and 24 hours was significantly lower in the US group (p≤0.05). Twenty-four hour postoperative opioid consumption was significantly lower in the US group (p≤0.05).
Conclusion: Ultrasound-guided bilateral superficial cervical plexus block is more effective in reducing pain both intra- and postoperatively compared with landmark technique in patients undergoing thyroidectomy.
