Epiglottitis and laryngotracheobronchitis.

Epiglottis and laryngotracheobronchitis are potentially life-threatening infections in the pediatric population. Unlike epiglottitis, laryngotracheobronchitis is very common. While both diseases may present with stridor and signs of respiratory obstruction, it is important to distinguish between them because the management strategies differ. Laryngotracheobronchitis usually responds to humidification. Epiglottitis requires an artificial airway and intensive antibiotics. The use of steroids remains controversial.
