Intravenous Acetaminophen/Ibuprofen Fixed-dose Combination on Postoperative Opioid Consumption

Not Applicable

Completed

• Conditions: Postoperative Pain
• Interventions: Drug: acetaminophen/ibuprofen fixed-dose combination; Drug: Saline

• Registration Number: NCT05366777
• Lead Sponsor: Seoul National University Hospital

Brief Summary

This prospective, randomized, double-blinded study is designed to evaluate the postoperative analgesic effect of the intravenous acetaminophen/ibuprofen fixed-dose combination in patients undergoing video-assisted thoracic surgery (VATS). We hypothesize that the intravenous acetaminophen/ibuprofen fixed-dose combination can significantly reduce postoperative opioid consumption and pain severity in patients with VATS.

Detailed Description

Adult patients undergoing elective unilateral VATS wedge resection, segmentectomy, or lobectomy are randomly allocated to receive intravenous acetaminophen (1000 mg)/ibuprofen (300 mg) fixed-dose combination (n=48) or not (n=48). At the end of induction, the intervention group will receive intravenous acetaminophen (1000 mg)/ibuprofen (300 mg) for 15 min, every 6 hours, a total of 4 times. The control group will receive intravenous normal saline with the same volume and same time points as the intervention group receives.
