Asbestosis is a disease with pulmonary interstitial fibrosis and pleural hypertrophy as the main pathological changes caused by long-term inhalation of asbestos dust. Asbestos is a natural mineral crystal, and its chemical composition is silicate complex containing iron, magnesium, aluminum, calcium, nickel and other elements. Asbestos fiber has the characteristics of acid resistance, alkali resistance, heat insulation and insulation, and is widely used in industry. Workers in mining, mineral processing and transportation of asbestos mines, sorting workers in asbestos processing plants and workers in insulation and heat insulation materials of asbestos products may suffer from occupational asbestosis due to long-term inhalation of asbestos dust. The length of service of onset is generally around 10 years. Clinically, patients mainly show symptoms of chronic bronchitis and emphysema, such as cough, expectoration, shortness of breath and chest pain. Symptoms and signs of pulmonary insufficiency and cor pulmonale appear in the late stage, and asbestos corpuscles can be detected in the sputum of patients.
Therefore, comprehensive treatment should be actively carried out. First of all, we should prevent complications, improve bad habits, such as smoking and drinking, prevent colds, actively treat complications to delay their development, and treat them according to the condition. Both drugs and lung lavage can prevent the development of pulmonary fibrosis.
