Acute pulmonary edema associated with intense laryngospasm during or after anesthesia seems to be a rare complication. Although emergency reestablishment of the airway may avert fatal hypoxia, subsequent morbidity may follow from the delayed effects of the obstruction. We recently observed a 16-year-old, 5kg boy, with inguinal hernia who developed laryngospasm and pulmonary edema following a herniorrhaphy and he had no evidence of cardiac enlargement or cardiovascular disease.
