Pulmonary hemorrhage accompanied with pulmonary edema induced by endotracheal tube occlusion in a child: A case report / 대한마취과학회지

Negative pressure induced pulmonary edema due to upper airway obstruction is a well-recognized problem. However, negative pressure pulmonary hemorrhage is extremely uncommon. We report a child who developed negative pressure pulmonary hemorrhage following acute airway obstruction caused by clench of endotracheal tube during emergence of anesthesia. The patient was treated with positive pressure ventilation and frequent tracheal suction. Hemorrhage from endotracheal tube was gradually decreased after 4 hours. The patient was extubated after 7 hours.
