PurposeIntravenous flurbiprofen, a non-steroidal antiinflammatory drug (NSAID), has been used recently for postoperative pain relief in adults. The drug is also likely to have antiemetic property. The present study was undertaken to investigate the effect of flurbiprofen on postoperative pain and emesis in children undergoing strabismus surgery, which is well known to produce postoperative nausea and vomiting.MethodsIn a prospective, randomised, controlled clinical trial, 90 children aged 2-11 yr received saline (control), flurbiprofen 0.5 mg.kg-1, or flurbiprofen 1 mg.kg-1. Saline and flurbiprofen were administered i.v. immediately after induction of anaesthesia. Anaesthesia was induced and maintained with sevoflurane and nitrous oxide in oxygen. Postoperative pain was assessed by a blinded observer using an objective pain scale (OPS). No opioids or antiemetics were administered throughout the study. The incidence and frequency of vomiting were compared among groups.ResultsFlurbiprofen 1 mg.kg-1 provided lower OPS (highest) scores during the eight hours after surgery and a reduced requirement for postoperative supplementary analgesic (diclofenac suppository) compared with the other two regimens. The two doses of flurbiprofen failed to decrease the incidence and frequency of vomiting.ConclusionThese data suggest that preoperative flurbiprofen 1 mg.kg-1 iv is a simple and effective approach to postoperative pain relief but not to the prevention of emesis following paediatric strabismus surgery.
