Nitrous oxide and postoperative vomiting in children undergoing myringotomy as a day case

Iain Wilson, David A. Fell

Abstract

Summary The effect of avoiding nitrous oxide during anaesthesia for myringotomy as an outpatient procedure in children aged 18 months to 10 yr was investigated. One hundred and four children were allocated randomly to receive either nitrous oxide, oxygen and halothane or oxygen and halothane for maintenance of anaesthesia. Ten of 47 (21%) children receiving nitrous oxide experienced postoperative vomiting, compared with two of 48 (4%) of those that did not receive nitrous oxide (P < 0.05). The possible mechanisms are discussed.
