Pulmonary haemorrhage associated with negative-pressure pulmonary oedema: a case report.

Negative-pressure pulmonary oedema caused by upper airway obstruction after tracheal extubation is well recognised, but extensive pulmonary haemorrhage is rare. We report a case of post-extubation, laryngospasm-induced pulmonary oedema with associated pulmonary haemorrhage. The patient required mechanical ventilation with high positive end-expiratory pressure.
