The latest diagnostic criteria and staging of pneumoconiosis

summary

Pneumoconiosis is a lung disease caused by long-term inhalation of dust particles and long-term accumulation in the lungs. It usually evolves into a systemic disease. Pneumoconiosis patients mainly come from coal miners, professional construction workers and so on. Patients with pneumoconiosis cough is not obvious, but with the aggravation of the disease, cough will be more and more serious, and appear the symptoms of expectoration, let's take a look at the following.

The latest diagnostic criteria and staging of pneumoconiosis

First: GB / t16180 identification of industrial injury and disability degree of occupational disease 3 diagnostic principles: according to reliable production dust exposure history, on-site labor hygiene investigation data, with qualified X-ray posteroanterior chest film performance as the main basis, with reference to dynamic observation data and epidemiological investigation of pneumoconiosis, combined with clinical manifestations and laboratory examination, After excluding other similar lung diseases, the diagnosis and X-ray staging of pneumoconiosis were made according to the diagnostic standard film of pneumoconiosis.

Second: X-ray chest film staging: no lung dust: X-ray chest film no dust lung performance; Chest X-ray findings are not enough to diagnose I. Stage I pneumoconiosis: there are small shadows with an overall density of grade 1, and the distribution range reaches at least two lung areas; Small shadows with overall density grade 1 were distributed in more than 4 lung areas, or small shadows with overall density grade 2 were distributed in 4 lung areas.

The third stage: stage II pneumoconiosis: there are small shadows with the overall density of grade 2, which are distributed in more than 4 lung areas; There may be small shadows with a total density of grade 3, distributed in four lung areas. There were small shadows with a total density of grade 3, distributed in more than 4 lung areas; Or there are small shadows gathering; There may be large shadow, but it is not enough to be diagnosed as Ⅲ. Stage III pneumoconiosis: there are large shadows, the long diameter is not less than 20 mm, the short diameter is not less than 10 mm. The area of single large shadow or the sum of multiple large shadow areas exceeds the area of right upper lung.

matters needing attention

Pneumoconiosis patients should be transferred from the dust work area in time, and timely to the hospital for examination and treatment. Workers who have been engaged in dust work for a long time should pay attention to reduce dust inhalation, such as wearing isolation masks, and regularly go to the hospital for examination to prevent the occurrence of pneumoconiosis.
