Pulmonary edema is well recognized complication of acute upper airway obstruction, especially in small children, but rarely seen in adults. It usually follows relief of the obstruction and is likely to be of noncardiogenic origin. The mechanism by which an upper airway obstruction causes pulmonary edema is likely due to the combination of the increased reductions in the interstitial hydrostatic pressure and increased capilary permeabillity. Hypoxia is another aggravating factor. We present a case of acute pulmonary edema caused by laryngospasm that occurred in an adult patient after treatment for upper airway obstruction following extubation of the traches.
