Brief Summary

The investigators hypothesize that pregabalin will decrease post-operative pain scores and analgesic use following robot-assisted endoscopic thyroidectomy compared to placebo. The primary outcome will be acute postoperative pain, measured by a verbal numerical rating score (VNRS) and total analgesic consumption during postoperative 48 hours. The secondary outcome will be the incidence of chronic pain and hypoesthesia in the anterior chest at 3 months after operation.

Outcome Measures

Primary Outcomes (3)

• Pain Scores (VNRS) at 1, 6, 24, 48 Hours Postoperatively.

  Pain was evaluated using an 11-point verbal numerical rating scale (VNRS). Patients were instructed preoperatively to express their pain on the 0-10 VNRS, where 0 means no pain at all, and 10 represents the worst pain imaginable

  1, 6, 24 & 48 hours

• The Number of Participants With the Indicated Side Effects - Nausea & Vomiting, Sedation, Headache, Dizziness Etc.

  Nausea and vomiting was graded on a four-point scale, where 0 = no nausea, 1 = mild nausea, 2 = severe nausea requiring antiemetics, and 3 = retching and/ or vomiting. Grades 3 and 4 were grouped together as postoperative nausea and vomiting (PONV) and rescue anti-emetic, metoclopramide 10 mg i.v. was given. We asked patients about sedation, headache, dizziness, blurred vision.

  1, 6, 24 & 48 hours

• Number of Patients Who Required Additional Analgesics During the First 48 Hours Postoperatively

  1, 6, 24 & 48 hours

Secondary Outcomes (1)

• Number of Patients With Hypoesthesia in the Anterior Chest at 3 Months After Operation.
