Anonymous users2024-02-13Pneumoconiosis is a systemic disease caused by long-term inhalation of productive dust (dust) during occupational activities and its retention in the lungs, mainly diffuse fibrosis (scarring) of lung tissue. Clinical manifestations of pneumoconiosis.
There are no specific clinical manifestations of pneumoconiosis, and its clinical manifestations are mostly related to comorbidities.
1. Cough The cough of early pneumoconiosis patients is not obvious, but with the development of the course of the disease, patients are more likely to have chronic bronchitis, and patients in the late stage are more likely to have lung infection, which can make the cough significantly worse. Cough is related to the season, climate, etc.
2. Sputum cough Sputum cough is mainly caused by the continuous removal of dust by the respiratory system. Generally, the amount of sputum is not much, and most of it is gray thin sputum. If there is pulmonary infection and chronic bronchitis, the amount of sputum will increase significantly, and the sputum will be yellow and viscous or lumpy. It is often difficult to cough up.
3. Chest pain Patients with pneumoconiosis often feel chest pain, and there is no correlation or parallel relationship between chest pain and clinical manifestations of pneumoconiosis. The location is different and often varied, and most of them are limited. It is generally a dull pain, but it can also be a swelling pain, pins and needles pain, etc.
4. Dyspnea With the aggravation of the degree of fibrosis of lung tissue, the effective breathing area decreases, the proportion of ventilation and blood flow is out of balance, and the dyspnea gradually increases. The occurrence of comorbidities can significantly increase the degree and rate of dyspnea.
5. Hemoptysis is relatively rare, and can cause mucosal vascular damage due to long-term chronic inflammation of the respiratory tract, with a small amount of blood streaks in sputum; It may also increase blood volume due to the lysis and rupture of large fibrotic lesions and damage to blood vessels.
6. Other In addition to the above-mentioned respiratory symptoms, there may be different degrees of systemic symptoms, and digestive function is often reduced.
Complications of pneumoconiosis.
Due to long-term exposure to productive dust, the defense function of the respiratory system is impaired, the patient's resistance is significantly reduced, and a variety of different complications often occur. 1. Respiratory infections are mainly pulmonary infections, which are common complications in patients with pneumoconiosis. 2. Spontaneous pneumothorax is less common.
It is the rupture of the pleura of the lung tissue and visceral layer, and the air enters the pleura to form a pneumothorax, which is divided into three types: closed pneumothorax, tension pneumothorax, and communicating pneumothorax. 3. Tuberculosis Dust workers, especially silica dust workers, are more susceptible to tuberculosis than the general population. 4. Lung cancer and pleural mesothelioma are mainly seen in asbestos workers and patients with asbestosis.
5. Chronic cor pulmonale is seen in some advanced patients, because chronic bronchitis narrows the airway, increases ventilation resistance, produces obstructive pulmonary gas, and increases pulmonary artery pressure, resulting in chronic cor pulmonale. 6. Respiratory failure Upper respiratory tract and lung infection, pneumothorax and other triggers are the main causes of decompensated respiratory failure, and the abuse of sedative and sleeping drugs is also one of the causes of respiratory exhaustion in pneumoconiosis.
Pneumoconiosis is a disabling occupational disease that has no medical termination. Patients with pneumoconiosis have chest tightness, chest pain, cough, sputum production, exertional dyspnea, susceptibility to colds, decreased respiratory function, which seriously affects the quality of life, and the condition will be upgraded every few years, combined with infection, and finally death from pulmonary heart disease and respiratory failure.

Anonymous users2024-02-11Pneumoconiosis is a disease caused by long-term inhalation of dust, mainly fibrous lesions of lung tissue. It is also believed that pneumoconiosis is the accumulation of dust in the lungs and the reaction of tissue coal workers' pneumoconiosis The ** of pneumoconiosis is the dust that causes pneumoconiosis by inlay.
There are 12 types of pneumoconiosis specified in the current national "List of Occupational Diseases": 1Sipei ( 2
Coal workers' pneumoconiosis (e) 3Graphitus pneumoconiosis (4.)Carbon black pneumoconiosis () 5

PneumoconiosisPneumoconiosis is a systemic disease caused by long-term inhalation of productive dust (dust) during occupational activities and its retention in the lungs, mainly diffuse fibrosis (scarring) of lung tissue. Pneumoconiosis can be divided into inorganic pneumoconiosis and organic pneumoconiosis according to the type of dust it inhales. Pneumoconiosis caused by inhalation of inorganic dust during production labor is called inorganic pneumoconiosis. >>>More
Integrated measures and approaches include:
1) Once silicosis is confirmed, the dust operation should be immediately transferred, and appropriate other work should be arranged according to the health and physical conditions at the time, and if possible, the labor intensity should be reduced or the working hours should be shortened. >>>More
Not necessarily, because like many other diseases that not everyone with risk factors will get, for example, not everyone who smokes will develop lung cancer. The incubation period of pneumoconiosis can be 5-15 years, during which you may not feel anything, since you have a history of close contact inhalation for half a year, you must first pay attention to it, of course, you don't need to go to the hospital if you have no symptoms, but you must go to the hospital for chest x-ray when you have symptoms (repeated cough, shortness of breath, poor breathing), at present, we mainly rely on chest imaging to diagnose pneumoconiosis, which can help you detect and **. Hope it helps!
Case analysis: There is no specific drug for pneumoconiosis at present, mainly comprehensive, the specific situation can be determined according to the condition, and individualized ** is used to control the condition.
No. However, due to certain infectious comorbidities (e.g., active tuberculosis) in patients with pneumoconiosis, it is possible to transmit tuberculosis. Some substances contained in dust, such as some inorganic substances that are difficult to be dissolved, can form a buildup in the alveoli, and the reason for the discovery is that the cough keeps dry, and the kind that can't stop coughing, the doctor said that there is a lot of dust in the lungs, what is pneumoconiosis? >>>More
