The significance of repetitive yawning in the emergency patient - A warning of imminent death or disability

Premortem yawning is absent from almost all major medical textbooks but has been associated for more than 2000  years with impending death from acute infections and hemorrhage and was commonly known during the Bubonic Plague pandemic [1,2]. Medical reports of premortem yawning identify multiple causes of shock including vasovagal reflex, severe hypoxia/anemia/hypoglycemia, stroke, and intracranial hyperten sion [3-5].
