A comparison of propofol and methohexitone for dental chair anaesthesia in children.

Fifty healthy children presenting for outpatient exodontia received either propofol or methohexitone for induction. Anaesthesia was maintained in both groups using 50% oxygen in nitrous oxide and 1-2% halothane. Those receiving methohexitone maintained a significantly higher mean arterial pressure and heart rate than the propofol group. Nine percent of patients in the propofol group developed ventricular arrhythmias, compared to 32% in the methohexitone group.
