Non-opioid analgesics are often used to supplement opioids for the management of perioperative pain. In this randomized, double-blinded, placebo-controlled study, we examined the effects of acetaminophen and a cyclooxygenase type-2 inhibitor, celecoxib, when administered alone or in combination, before elective otolaryngologic surgery in 112 healthy outpatients. Subjects were assigned to 1 of 4 study groups: Group 1, placebo (vitamin C, 500 mg per os [PO]); Group 2, acetaminophen 2000 mg PO; Group 3, celecoxib 200 mg PO; or Group 4, acetaminophen 2000 mg and celecoxib 200 mg PO. All patients received a standardized anesthetic technique. During the postoperative period, pain was assessed using a 10-point verbal rating scale. Recovery times, the need for rescue analgesics, side effects, and patient satisfaction scores were also recorded. The combination of acetaminophen and celecoxib was significantly more effective than placebo in reducing postoperative pain. Celecoxib, when administered alone or in combination with acetaminophen, improved patients' satisfaction with their postoperative analgesia. With the combination of acetaminophen and celecoxib, an additional expenditure of $6.16 would be required to obtain complete satisfaction with postoperative pain management in one additional patient who would not have been completely satisfied if he/she had received the placebo. However, oral celecoxib or acetaminophen alone was not significantly more effective than placebo in reducing postoperative pain when administered before surgery. We conclude that oral premedication with a combination of acetaminophen (2000 mg) and celecoxib (200 mg) was highly effective in decreasing pain and improving patient satisfaction after outpatient surgery.
