Abstract:
This randomized, double blinded, placebo controlled, prospective study compared the anti-emetic efficacy of one preoperative dose of metoclopramide 0.25 mg.kg-1 intravenously or ondansetron 0.15 mg.kg-1 intravenously with two doses of the same drugs (second dose administered one h postoperatively) in 200 preadolescent children undergoing tonsillectomy with either isoflurane or propofol anaesthesia. The incidence of posttonsillectomy vomiting was significantly reduced (P < 0.005) by two doses of either metoclopramide or ondansetron (18% and 8%, respectively) compared with placebo (50%). No difference in posttonsillectomy vomiting exists between the children who received isoflurane and those who received a propofol infusion. Our results suggest that two doses of metoclopramide 0.25 mg.kg-1 intravenously, like two doses of ondansetron 0.15 mg.kg-1, are effective in reducing vomiting after tonsillectomy in children who have received either isoflurane or propofol anaesthesia.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
