About this trial

This is an interventional treatment trial for Pain, Postoperative focused on measuring thyroidectomy, pain, postoperative, pregabalin

Eligibility Criteria

20 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. American Society of Anesthesia physical status class I & II
  2. Age ≥ 20 and ≤ 65 years
  3. Robot- assisted endoscopic thyroidectomy

Exclusion Criteria:

  1. Known or suspected allergy, sensitivity, or contraindication to pregabalin or any of the standardized medications
  2. Body mass index ≥ 40 kg/m2
  3. History of seizure disorder
  4. Current therapy with pregabalin, gabapentin, or any opioid
  5. Any other physical or psychiatric condition which may impair their ability to cooperate with post-operative study data collection
  6. Insulin-dependent diabetes mellitus
  7. Renal insufficiency (estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2)

Sites / Locations

  • Department of Anesthesiology and Pain Medicine and Anesthesia and Pain Research Institute, Yonsei University College of Medicine

Arms of the Study

Arm 1

Arm 2

Arm Type

Placebo Comparator

Experimental

Arm Label

Placebo

Pregabalin

Arm Description

Patients receive oral Placebo 150 mg 1 hour prior to surgery, and 12 hours later

Patients receive oral pregabalin 150 mg 1 hour prior to surgery, and 12 hours later

Outcomes

Primary Outcome Measures

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

Secondary Outcome Measures

Number of Patients With Hypoesthesia in the Anterior Chest at 3 Months After Operation.
we checked Hypoesthesia in the anterior chest at 3 months after operation by phone.

5. Study Description

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.
