OBJECTIVE: We tested the hypothesis that the mechanism of respiratory insufficiency in drug-induced coma involving benzodiazepines is an increase in upper airway resistance. METHODS: Eighteen nonintubated and seven intubated (control) patients were poisoned with hypnotic sedatives involving benzodiazepines. Neurological and respiratory parameters were measured by polysomnography before and after flumazenil. ...
