The effect of premedication on the incidence of postoperative vomiting in children after E.N.T. surgery.

The influence of premedication and intraoperative narcotic administration on the incidence of vomiting after E.N.T. surgery was studied over a six-month period in 596 children. A high incidence of vomiting was found after intramuscular papaveretum and hyoscine and after oral diazepam. Oral trimeprazine tartrate was associated with a low incidence of vomiting and was found to have an anti-emetic effect when an opiate analgesic was administered after induction of anaesthesia.
