AbstractIn children, strabismus surgery is frequently followed by vomiting. The present study compares the antiemetic effects of droperidol (10 micrograms/kg) and/or metoclopramide (0.1 mg/kg) in 104 children undergoing strabismus surgery. The patients were randomly divided into four groups. Group I (n = 28) received placebo (saline), Group II (n = 26) droperidol 10 micrograms/kg, Group III (n = 25) metoclopramide 0.1 mg/kg and Group IV (n = 25) droperidol 10 micrograms/kg and metoclopramide 0.1 mg/kg. Droperidol was given just after induction and metoclopramide at the end of surgery, just before recovery. The technique of anesthesia involved an anticholinergic premedication, IV fentanyl (2 micrograms/kg), controlled ventilation using isoflurance and N2O in oxygen and systematic gastric emptying before extubation. Vomiting, retching and nausea were noted at 5 different moments: in the Post Anesthetic Care Unit, when arriving on the ward (= after carriage by lift), during the first hour following the return in the ward, from the 6th to the 12th postoperative hour and on the morning of day 1. There was no statistically significant difference in the incidence of vomiting among these four groups. Moreover, the incidence of vomiting in the placebo group was much lower (17.9% in the recovery room, 3.6% at return in the ward, 25% during the first hour, 7.1% from 6 to 12 hours and 3.6% the next day) than that reported in previous studies. We think that this could result from the additive effects of some aspects of the technique of anesthesia described and discussed in this paper.
