Synopsis

Upper airway obstruction is a narrowing of the oropharynx, larynx, or trachea. It is often a medical emergency.
  • In children, upper airway obstruction is primarily allergic, infectious (croup, epiglottitis, abscess), or caused by foreign body aspiration.
  • While adults may also suffer from upper airway obstruction of an infectious etiology, it is more commonly caused by malignancy, trauma, or inflammatory diseases.
Upper airway obstruction characteristically presents with stridor. Signs of more severe airway obstruction include respiratory distress, tachypnea, use of accessory muscles of respiration, and agitation. Severe upper airway obstruction can cause abnormalities of blood gases.

Treatment is dependent on the underlying etiology; however, intubation may be required in severe cases regardless of the cause.
