How to diagnose interstitial pneumonia?

summary

How to diagnose interstitial pneumonia needs to make a comprehensive judgment according to the specific situation of patients, epidemic trends and slight changes of symptoms. In the case of secondary pneumonia, the primary symptoms may mask the symptoms of pneumonia. This requires doctors to have a high degree of vigilance, always think of the possibility of pneumonia, and then a few sounds of the lung may prompt the existence of pneumonia. It is not difficult to diagnose interstitial pneumonia in typical cases with fully developed disease according to epidemic trends, specific history, systemic poisoning symptoms, signs of pulmonary inflammatory consolidation, X-ray and laboratory findings. How to diagnose interstitial pneumonia.

How to diagnose interstitial pneumonia?

First: one of the diagnosis of interstitial pneumonia, chest imaging examination: the early abnormal signs of chest X-ray are ground glass shadow, increased lung markings, which are often ignored. Further development of the disease, there may be extensive reticular shadow, reticular nodular shadow, nodular shadow, and so on. In the late stage, it showed honeycomb lung like changes, and the lesions often involved both lung fields.

Second: the second diagnosis of interstitial pneumonia, many patients, mostly insidious onset, progressive exacerbation of exertional dyspnea is the most common symptoms, usually accompanied by dry cough, fatigue, the main sign is shallow and fast breathing, with double lower lungs as the main crackle, late pulmonary hypertension and right ventricular hypertrophy, often died of respiratory failure or (and) heart failure.

Third: occupational exposure to exogenous antigens accounts for a considerable proportion, so medical history and occupational history may provide important diagnostic clues. We should collect detailed information on past history of occupation, hobbies and medication. If the total lung volume, vital capacity and functional residual capacity decrease, and there is no increase of airway resistance, mild patients may have no hypoxemia at rest.

matters needing attention

The above several diagnostic methods for interstitial pneumonia are commonly used in clinic. In addition, experts suggest that the treatment of interstitial pneumonia is very difficult.
