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

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

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.

Inclusion Criteria:

• ASA class 1 or 2 adult patients scheduled for robot-assisted endoscopic thyroidectomy

Exclusion Criteria:

• Patient refusal
• Bleeding diathesis
• Allergies to local anesthetics
• Patient unable to read consent form (Foreigner, illiterate)
