两肺广泛浸润或多叶毁损的进展期肺结核,常发生呼吸衰竭,严重低氧血症是引起死亡的主要原因。纤维支气管镜(纤支镜)介入治疗,包括吸除痰液、支气管肺泡灌洗、导管注药,既能充分清除气道分泌物,又能注入高浓度抗生素,起到疏通气道、强化抗结核、改善呼衰、挽救生命的治疗作用,但 Extensive infiltration of lungs or lobes of advanced pulmonary tuberculosis, often respiratory failure, severe hypoxemia is the main cause of death. Fiberoptic bronchoscopy (bronchoscopy) interventional therapy, including aspiration sputum, bronchoalveolar lavage, catheter injection, both to fully clear the airway secretions, but also to inject high concentrations of antibiotics, play dredging the airway, enhanced anti- Tuberculosis, to improve respiratory failure, saving lives, but
