Recognition and emergency management of infectious causes of upper airway obstruction in children.

Infections represent one of the most common causes of upper airway obstruction in the pediatric age group. Because obstructive processes may lead to respiratory failure and subsequent cardiopulmonary arrest, prompt recognition is crucial. This discussion provides a brief review of the unique anatomic and physiological characteristics of the child's airway, which may contribute to obstructive processes, followed by basic principles of pediatric airway management. Finally, we review many of the infectious causes of upper respiratory obstruction, with emphasis on early recognition and acute management.
