Aluminum pneumoconiosis

Aluminum Pneumoconiosis Pulmonary aluminous fibrosis refers to pulmonary fibrosis caused by long-term inhalation of ultra-fine metal aluminum powder. basic knowledge The proportion of sickness: 0.002% - 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: emphysema, tuberculosis

Aluminum pneumoconiosis

(1) Causes of the disease

Lung lesions caused by long-term inhalation of metal aluminum powder or alumina dust.

(two) pathogenesis

The disease refers to the work in the production and use of metal aluminum powder or alumina-containing dust, long-term inhalation of dust caused by diffuse pulmonary fibrosis in the lungs of pulmonary aluminous fibrosis.

Aluminum pneumoconiosis prevention

The main measures are free from the dust working environment.

Aluminum pneumoconiosis Complications emphysema tuberculosis

Late emphysema, pulmonary infection or tuberculosis.

Aluminum pneumoconiosis symptoms Common symptoms weakness chest tightness fatigue pharyngeal chronic congestion chest pain nasal dryness and crusting shortness snoring congestion

The incidence of bauxal fibrosis is longer, usually 10 to 15 years, the symptoms are less and lighter, in addition to shortness of breath, chest tightness, chest pain, there may be a slight cough, hemoptysis is rare, burnout, weakness is also more common Due to the mechanical stimulation and chemical action of aluminum dust, there is often chronic damage of the nasopharynx, manifested as nasal mucosa congestion, nasal dryness, turbinate hypertrophy, chronic congestion of the pharynx, inflammation, usually no signs in the lungs, and bronchial and pulmonary When the infection is infected, it can be smelled dry and wet.

Aluminum pneumoconiosis

Blood phosphorus is high and blood calcium is low.

The chest X-ray examination is characterized by irregular small shadows (fine mesh shadows), accompanied by a number of thick irregular large shadows (rough mesh shadows) and a few small round shadows, about 1 to 2 mm in diameter. There is no large shadow of the fusion mass, the pleura can be mildly sticky and hypertrophic, emphysema changes are more common, pulmonary function tests are mostly obstructive ventilatory disorders, followed by mixed type.

Aluminum pneumoconiosis diagnosis

diagnosis

1. Occupational medical history has an accurate and reliable history of occupational exposure to aluminum powder.

2. Diagnosis can be based on clinical manifestations and laboratory tests and pulmonary dysfunction.

Differential diagnosis

It should be differentiated from emphysema, pneumonia and tuberculosis.
