Diffuse alveolar hemorrhage (DAH) is an acute, life-threatening event. The blood-gas barrier must be very thin to allow gas exchange and is therefore subjected to high mechanical stresses when the capillary pressure rises. In general anesthesia, inhaled gases cause high mechanical stresses, and thus DAH occurs under certain conditions. We describe a case of inferred postoperative DAH. A 25-year-old man had an acute episode after undergoing a tonsillectomy for snoring. During surgery, no problems occurred and no marked bleeding was observed. After removal of the endotracheal tube, however, the patient had severe cough and hemoptysis. The patient was treated with an antihemorrhagic agent and antibiotics. He recovered after 1 week. Chronic snoring likely caused the alveolar damage in this patient and intubation led to DAH. The patient presented with a benign course that regressed spontaneously with medical intervention.
弥漫性肺泡出血 (DAH) 是一种急性的、危及生命的事件。为了实现气体交换，气血屏障必须非常薄，因此当毛细血管压力升高时，它会受到很高的机械应力。在全身麻醉中，吸入的气体引起很高的机械应力，因此在某些情况下会发生 DAH。我们描述了一例推测的术后 DAH。一名 25 岁男性因打鼾接受扁桃体切除术，术后出现急性发作。手术过程中没有出现问题，也没有明显的出血。然而，在拔出气管导管后，患者出现严重的咳嗽和咯血。患者接受了止血剂和抗生素治疗。他在 1 周后康复。该患者的慢性打鼾可能导致肺泡损伤，插管导致 DAH。患者表现出良性的病程，经药物干预后自发消退。
