重症肺结核由于广泛肺组织受损,引起肺容量、通气量、有效弥散面积减少或通气/血流比例失调,常常伴发慢性呼吸衰竭(呼衰),一旦发生呼吸道感染,或因其他原因增加呼吸生理负担,即加重缺O_2和CO_2潴留,出现危重症状,常是肺结核患者致死原因之一。本文就资料完整的临床诊断为肺结核呼衰的46例患者(58例次)进行回顾性分析,探讨重症肺结核伴呼衰的救治。 1 资料来源 Severe pulmonary tuberculosis due to extensive lung tissue damage, causing lung capacity, ventilation, effective diffusion area reduction or ventilation / blood flow imbalances, often accompanied by chronic respiratory failure (respiratory failure), respiratory infections occur, or for other reasons to increase breathing Physiological burden, that increase lack of O2 and CO2 retention, the emergence of critical symptoms, often one of the causes of death in patients with tuberculosis. In this paper, a complete analysis of the clinical diagnosis of pulmonary tuberculosis respiratory failure in 46 patients (58 cases) were retrospectively analyzed to discuss the treatment of severe tuberculosis with respiratory failure. 1 Source
