AbstractThis study was undertaken to compare the efficacy of granisetron plus droperidol with each antiemetic alone for the prevention of vomiting after paediatric strabismus surgery. In a prospective, randomized, double-blinded trial, 120 ASA physical status I children, aged 4-10 years, received granisetron 40 microg.kg- 1, droperidol 50 microg.kg- 1, granisetron 40 microg.kg- 1 plus droperidol 50 microg.kg- 1 (n=40 of each) intravenously after an inhalation induction of anaesthesia. A complete response, defined as no vomiting, no retching and no need for another rescue antiemetic medication, during 0-3 h after anaesthesia was 80% with granisetron, 45% with droperidol and 98% with granisetron plus droperidol, respectively; the corresponding incidence during 3-24 h after anaesthesia was 78%, 38% and 98% (P< 0.05; overall chi-squared test with Yates continuity correction). No clinically important adverse events were observed in any of the groups. In conclusion, a combination of granisetron and droperidol was more effective than granisetron or droperidol as a sole antiemetic for the prevention of postoperative vomiting in children undergoing strabismus repair.
