Editing Tracheal intubation (section)

===Airway obstruction===
Actual or impending airway obstruction is a common indication for intubation of the trachea. Life-threatening airway obstruction may occur when a [[foreign body]] becomes lodged in the airway; this is especially common in infants and toddlers. Severe [[blunt trauma|blunt]] or [[penetrating trauma|penetrating]] injury to the face or neck may be accompanied by [[edema|swelling]] and an expanding [[hematoma]], or injury to the [[Tracheobronchial injury|larynx, trachea or bronchi]]. Airway obstruction is also common in people who have suffered [[smoke inhalation]] or burns within or near the airway or [[epiglottitis]]. Sustained [[Tonic–clonic seizure|generalized seizure activity]] and [[angioedema]] are other common causes of life-threatening airway obstruction which may require tracheal intubation to secure the airway.<ref name=Ezri2007/>
