title: Depression of laryngeal reflexes during keatmine anaesthesia.
abstract: The competence of the laryngeal-closure reflex was assessed in a group of patients having ketamine anaesthesia and found to be depressed. All patients in a control group of conscious volunteers had a competent reflex. The possible dangers of ketamine anaesthesia without endotracheal intubation are discussed.
