title: Comparative study of lorazepam and trimeprazine for oral premedication in paediatric anaesthesia.
abstract: One hundred and ninety-nine children received lorazepam 0.05 mg kg-1 or trimeprazine 3 mg kg-1 as oral premedication in a double-blind trial. Lorazepam proved more palatable and produced a cheerful demeanour, but possessed no significant advantages on overall assessment before surgery. Following operation, restlessness with vomiting, and evidence of retrograde amnesia occurred more frequently with lorazepam.
