Abstract: | Purpose Dexamethasone decreases chemotherapy-induced emesis when added to antiemetic regimens. This study was designed to compare the effectiveness of granisetron and dexamethasone with granisetron alone in the prevention of postoperative vomiting after strabismus repair, tonsillectomy with or without adenoidectomy in children. Methods In a randomized, double-blind study, 60 healthy children, 4–10 yr of age, received either granisetron 40 μg · kg?1 and saline (Group S) or granisetron 40 μg · kg?1 and dexamethasone 4 mg (Group D) iv immediately after the induction of anaesthesia. All subjects received anaesthetics consisting of sevoflurane and nitrous oxide in oxygen. Postoperative pain was treated with acetaminophen pr or pentazocine iv. Postoperatively, during the first 24 hr after anaesthesia, the frequencies of retching and vomiting, and the incidence of adverse events were recorded by nursing staff. Results There were no differences between the treatment groups with regard to demographics, surgical procedure, anaesthetic administered or analgesics used for postoperative pain. The frequency of the symptoms was 27% and 7% in Groups S and D, respectively (P < 0.05). The incidence of adverse events was comparable in the two groups. Conclusion The prophylactic administration of granisetron and dexamethasone was more effective than granisetron alone in the prevention of postoperative vomiting in paediatric subjects undergoing strabismus repair, tonsillectomy and adenoidectomy. |
