title: Sudden drooling and supine gagging: an important emergency?
abstract: We describe a case of an eupnoeic patient complaining of a foreign body sensation in his mouth and throat, with sudden drooling and supine gagging. This condition was caused by an isolated uvular angioedema (Quincke's oedema). As this uvular hydrops did not decrease with initial standard therapy for angioedema, epinephrin was applied directly on the swollen uvula, causing it to shrink very rapidly. Isolated uvular oedema is a potentially life-threatening condition with risk of sudden upper airway obstruction, and should therefore be recognized and treated as soon as possible. As described in this case, its initial presentation can consist of gagging and drooling without dyspnoea, thus causing a real challenge for triage and diagnosis.
