Hemoptysis is usually a symptom of cardiopulmonary disease and is generally not in itself associated with death. A blood loss into the tracheobronchial tree of 600 ml in 24 hours or at a rate that poses a threat to life is referred to as massive hemoptysis. Hypervascularity within the bronchial circulation, usually associated with diffuse inflammatory disease of the lung, is common in patients with massive hemoptysis. Management should be directed at maintenance of oxygenation and localization of the source of bleeding. Temporizing maneuvers such as iced saline lavage, intravenous administration of vasopressin, endobronchial tamponade and bronchial artery embolization will often stabilize the patient in preparation for definitive surgery. Such a sequential plan of management may result in a 50% reduction in the rate of death from massive hemoptysis, which is otherwise 50% to 100%.
咯血通常是心肺疾病的症状,一般本身并不与死亡相关。24小时内气管支气管树失血600毫升或以对生命构成威胁的速度失血被称为大咯血。支气管循环内血管增多,通常与肺部弥漫性炎症性疾病有关,在大咯血患者中很常见。治疗应旨在维持氧合和确定出血源的位置。诸如冰盐水灌洗、静脉注射血管加压素、支气管内填塞和支气管动脉栓塞等临时措施通常可使患者病情稳定,为确定性手术做好准备。这样的序贯治疗方案可能会使大咯血死亡率降低50%,否则大咯血死亡率为50%至100%。
