Effect of low dose droperidol on postoperative vomiting in children.

This double-blind study assessed the effect of low dose droperidol (0.005 mg x kg-1) on the incidence of postoperative vomiting in 200 children in ASA classification I and II, ranging from one to 15 years of age. The results showed that the dose of droperidol used in this study was very effective in reducing vomiting in children 11 to 15 years of age. The duration of stay in the post-anaesthetic care unit was not prolonged and no extrapyramidal symptoms related to the drug were observed. In our opinion the administration of droperidol 0.005 mg x kg-1 before the end of the operation will reduce the possibility of vomiting within 24 hours of operation in children in 11-15 year age group who are expected to have a high incidence of postoperative vomiting.
