Post-extubation stridor (PES) is a frequent complication of intubation, occurring in 2-16% of cases. It is caused by laryngeal oedema that results from damage to the mucosa of the larynx. Mucosal damage is caused by pressure and ischaemia resulting in an inflammatory response. Laryngeal oedema, in severe cases, can lead to acute respiratory compromise necessitating emergency reintubation.
Female gender is a risk factor for both laryngeal oedema and PES. This predisposition has been hypothesised to be due to the female mucous membrane being less resistant to trauma and thinner than that in men.
Other risk factors include
Intubation >36 hours
Excessive cuff pressure
Large tube size
Age and asthma are not known risk factors for PES.
