Perioperative Administration of Pregabalin for Pain After Robot-assisted Endoscopic Thyroidectomy

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.

Vitamin Complex (placebo)

Drug

Vitamin Complex 150 mg orally

Primary outcomes

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

    Time frame: 1, 6, 24 & 48 hours

    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

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

    Time frame: 1, 6, 24 & 48 hours

    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.

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

    Time frame: 1, 6, 24 & 48 hours

Secondary outcomes

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

    Time frame: 3 months

    we checked Hypoesthesia in the anterior chest at 3 months after operation by phone.
