['Decreased consciousness is a common reason for presentation to the emergency department (ED) and admission to acute hospital beds. In trauma, a Glasgow Coma Scale score (GCS) of 8 or less indicates a need for endotracheal intubation. Some advocate a similar approach for other causes of decreased consciousness, however, the loss of airway reflexes and risk of aspiration cannot be reliably predicted using the GCS alone.', 'A survey of all poisoned patients with a decreased GCS who were admitted to an ED short-stay ward staffed by experienced emergency physicians, to establish the incidence of clinically significant aspiration or other morbidities and endotracheal intubation.', 'A prospective, observational study was conducted of all patients admitted to the ED short-stay ward with a decreased level of consciousness (GCS < 15).', 'The study included 73 patients with decreased consciousness as a result of drug or alcohol intoxication. The GCS ranged from 3 to 14, and 12 patients had a GCS of 8 or less. No patient with a GCS of 8 or less aspirated or required intubation. There was one patient who required intubation; this patient had a GCS of 12 on admission to the ward.'] Does decreased Glasgow Coma Scale score mandate endotracheal intubation in the emergency department?
