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.
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.
