报告８例慢性肺原件心脏病为主要临床表现引起的重症呼吸衰竭患考，常规治疗不能缓解，经气管切开、机械通气及支气管肺泡灌洗术（ＢＡＬ）抢救成功。结果表明，纤支镜ＢＡＬ术可清除阻塞气道的粘调痰，改善通气，同时气道内局部使用抗生素与激素，提高支气管内亢生素有效浓度，起到了净化气道作用，配合选用敏感抗生素、氧疗与营养支持疗法等，促进肺部炎症吸收，因而呼吸状况逐渐好转，ＰａＣＯ＿２下降，ＰａＯ＿２上升，使受损器官功能相继恢复。提示：综合抢救是提高抢救成功率的关键，而ＢＡＬ术是抢救呼吸衰竭患者的一种安全有效措施。
The report of 8 cases of chronic pulmonary heart disease as the main clinical manifestations of severe respiratory failure test, conventional treatment can not be alleviated, tracheotomy, mechanical ventilation and bronchoalveolar lavage (BAL) rescue success. The results showed that the bronchofiberscopy BAL operation can clear the sticky sputum blocking the airway, improve ventilation, while the local use of antibiotics and hormones in the airway to improve the effective concentration of bronchial endogenous vitamins, play a role in purifying the airway, with the selection of sensitive antibiotics, oxygen Treatment and nutritional support therapy, promote lung inflammation absorption, and thus gradually improve the respiratory status, PaCO_2 decreased PaO_2 rise, so that damaged organ function have been restored. Tip: Comprehensive rescue is to improve the success rate of rescue the key, and BAL surgery is a safe and effective rescue rescue patients with respiratory failure.
