AbstractNon-steroidal anti-inflammatory drugs (NSAID) effectively reduce the need for opioid analgesia after various types of surgery. The efficacy of diclofenac and ketoprofen to relieve pain after maxillofacial surgery was compared in the present study. In a randomized and double-blind fashion, 90 ASA I-II patients (16-60 yrs) were studied, divided into three groups: Thirty patients received 1.0 mg.kg-1 diclofenac i.v. after general anaesthesia induction, before surgical incision, and four hours later the same dose was given i.m. Thirty patients received ketoprofen 1.35 mg.kg-1 i.v. and i.m., as above, and a third group of 30 patients received a comparable volume of saline i.v. and i.m. The patients received supplemental analgesia using a patient controlled analgesia apparatus; the rescue medication consisted of 0.03 mg.kg-1 oxycodone i.v. (four-hour maximum dose was 0.4 mg.kg-1) during the 24-hour follow-up. The three groups were comparable regarding the type of maxillofacial surgery (osteotomies vs. soft tissue surgery). Overall, there was a lower need for i.v. oxycodone during the 24-hour period in the diclofenac group (269 doses) than in the ketoprofen group and in the saline group (388 doses, each) (P < 0.01). The significantly lower number of oxycodone administrations in the diclofenac group was a result of a distinguishable difference, particularly during the first four hours after surgery. There was no statistically significant difference in the incidence of side effects of the analgesic therapy between the three groups.
