Postobstructive pulmonary edema that developed immediately after the removal of an endobronchial foreign body.

The patient was a 5-year-old boy who was transported to our hospital for a paroxysmal cough, disturbance of consciousness, tonic-clonic convulsions and labored breathing. The patient's respiratory failure persisted after the convulsions remitted, and the presence of an endobronchial foreign body was suspected based on the findings of chest CT performed the following day. A peanut was subsequently removed from the right main bronchus using a bronchoscope with tracheal intubation and bag valve mask ventilation. Immediately after removal, the patient rapidly developed exacerbated hypoxemia, and a reduction in right lung lucency was noted on chest radiography. He was therefore diagnosed with type II postobstructive pulmonary edema, and his condition improved within a short period of time.
