[Two cases of acute pulmonary edema secondary to laryngospasm]

We report two cases of acute pulmonary edema attributable to episodes of postextubation laryngospasm appearing when two young patients awoke after appendectomies under general anesthesia. Both patients improved in less than 48 hours with diuretics, oxygen therapy and liquid restriction, making tracheal intubation unnecessary. The pathophysiology and clinical and radiological signs of pulmonary edema are reviewed.
