AI Article Synopsis

Article Abstract

Background: Although various analgesics have been used, postoperative pain remains one of the most troublesome aspects of tonsillectomy for patients.

Objective: The aim of the present study was to evaluate the effectiveness of premedication using pregabalin compared with placebo (diazepam) on postoperative pain control in patients undergoing tonsillectomy.

Methods: Forty-eight adult patients were randomly divided into a control group and a pregabalin group. Preoperatively, patients in the control group received 4 mg diazepam orally as placebo, whereas those in the pregabalin group received 300 mg pregabalin orally. All participants were provided with patient-controlled analgesia using fentanyl for 24 hours after surgery. Postoperative pain treatment included acetaminophen 650 mg three times daily for 8 postoperative days. The primary outcome measure was the total amount of patient-controlled fentanyl consumption after tonsillectomy. Secondary outcome measures were the number of injections of ketorolac tromethamine (each 30 mg) requested by patients, pain scores, overall satisfaction scores, drowsiness, nausea, dizziness, headache, and vomiting after the surgery. P < 0.05 was considered statistically significant.

Results: The total amount of fentanyl demanded decreased significantly in the pregabalin group (P < 0.001). There were no significant differences in the number of ketorolac tromethamine injections, pain scores, overall satisfaction scores, drowsiness, nausea, dizziness, headache, and vomiting between the two groups.

Conclusion: Administration of 300 mg pregabalin prior to tonsillectomy decreases fentanyl consumption compared with that after 4 mg diazepam, without an increased incidence of adverse effects.

Trial Registration: KCT0001215.
