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.
上气道梗阻所致负压性肺水肿是一个已被充分认识的问题。然而，负压性肺出血极为罕见。我们报告一例患儿，在麻醉苏醒期因气管插管咬紧导致急性气道梗阻后发生负压性肺出血。该患者接受了正压通气和频繁的气管吸引治疗。4小时后气管插管出血逐渐减少。7小时后患者拔除气管插管。
