Analgesic Efficacy of Bilateral Superficial Cervical Plexus Block in Robot-assisted Endoscopic Thyroidectomy Using a Transaxillary Approach

Not Applicable

Completed

• Conditions: Thyroid Cancer
• Interventions: Procedure: placebo; Procedure: Bilateral superficial cervical plexus block; Procedure: Control group

• Registration Number: NCT01325857
• Lead Sponsor: Yonsei University

Brief Summary

This study was designed to investigate the analgesic effect of bilateral superficial cervical plexus block in patients undergoing robot-assisted endoscopic thyroidectomy. The investigators hypothesized that bilateral superficial cervical plexus blockade would reduce the patient's pain score by more than 10 (on a VAS scale of 0\~100) compared to a placebo group and control group.
