Interstitial pneumonia is a type of lung disease
Early patients can be cured clinically after treatment
However, if the treatment is not timely or the treatment is not thorough
evolved into
and the cure rate is lower after interstitial fibrosis of the lung
, so it is very important to diagnose early in
Interstitial pneumonia
& pulmonary fibrosis
The early symptoms are not obvious
often confused with other diseases
What examinations can be used to determine the patient's condition?
medical history examination
In clinical practice, most patients with pulmonary fibrosis only come to the hospital for examination after dyspnea and dry cough.
For patients who visit this type of medical treatment, generally, they can use medical history examination to understand the patient's occupational characteristics, whether they have a smoking history, and whether they have a history of connective tissue disease.
Lung CT examination
Interstitial pneumonia is mainly confirmed by lung CT examination. If necessary, high-resolution CT examination can be tried.
especially high-resolution CT examination can accurately view the patient's lung blood vessels and bronchial blood vessels, which is conducive to arranging treatment measures.
Pulmonary fibrosis is a relatively serious lung pathological lesion. In severe cases, it may die directly. Therefore, after pulmonary fibrosis occurs, lung CT can be used to initially diagnose whether there is any fibrosis.
However, pulmonary CT examination can only intuitively observe the symptoms of pulmonary fibrosis, and it often needs to be combined with other clinical examinations to confirm the diagnosis.
chest X-ray flat film
Early pulmonary fibrosis patients can show blurred in the lower lung field such as ground glass-like density increase shadow, suggesting the pathological basis of alveolar sexual infiltrating lesions, which is the characteristic of alveolaritis X-ray.
As the disease progresses, linear cord-like texture appears in the lung field, which is intricate like a fine grid, called a mesh shadow. In the late stage of
, thick lines and thick reticulum appear. When the alveolar atresia and the bronchioles are compensated and expanded into a cystic shape, and the surroundings are surrounded by a large amount of fiber connective tissue, honeycomb lungs appear on the chest radiograph.
Most of them have no mediastinal , hilar area lymph nodes enlarged , pleural is not violated, but pneumothorax is often caused by rupture of the lung vesicular rupture.
blood test and arterial blood gas analysis
Due to inflammatory lesions in patients with interstitial pneumonia, the diagnosis can be confirmed through blood test and arterial blood gas analysis.
, especially the significant characteristics of this disease are abnormal immune cells, and patients will experience abnormal increase in breathing times and sudden drop in blood pressure. In particular, the diagnosis rate of arterial blood gas analysis is extremely high, which is conducive to early detection and early treatment.
Pulmonary function test
In addition to undergoing lung CT examination, patients with suspicion of pulmonary fibrosis can also selectively use lung function tests based on their actual situation.
During the lung function examination, a large number of alveolar collapses, dense scars or honeycomb-like pathological changes will occur.
But it should be noted that lung function examination is only used to cooperate with lung CT examination to check the patient's lung function and cannot be used as the basis for diagnosing this disease.
rheumatism and immune examination
pulmonary fibrosis patients can also conduct examinations through various methods such as rheumatism and immune examination and blood gas analysis. These examination methods can accurately detect the onset of the lung fibrosis and the degree of lesion to a large extent, providing a scientific reference for the next step of treatment.
serum cadmium examination
Normal adult cadmium load is 30-45 mg, which continues to accumulate after birth, causing the cadmium concentration in the body to increase with age until it is around 50 years old. Cadmium is mainly excreted from urine.
When the zinc/cadmium ratio in the human kidney decreases significantly (i.e. ≤1.5), it is a cause of hypertension. Acute cadmium poisoning has acute gastroenteritis or acute chemical pneumonia and pulmonary edema. Chronic cadmium poisoning includes kidney damage, proteinuria , emphysema , pulmonary fibrosis and other manifestations.
pulse oscillation lung function
pulse oscillation lung function (IOS) determination technology is a new instrument and equipment that integrates pulse forced oscillation away and computer spectrum analysis technology.
The advantage is that the subject can breathe independently without cooperation. The test process is more physiological and repeatable, and the results can better reflect the dynamic characteristics of the patient's respiratory physiology.
clinical application scope is pulmonary fibrosis, lung tumor, lung cyst , chronic bronchitis, bronchial asthma, emphysema, etc.
lung biopsy
If you want to be 100% confirmed, you can try lung biopsy and other examination methods. Pulmonary biopsy refers to percutaneous lung vibration tissue examination, which is divided into two types: fiber bronchoscopy technology and pleural biopsy.
However, this examination method will cause pain to the patient, but the diagnosis results are relatively accurate.
Although the above lists nine types of tests to confirm the diagnosis, in fact, interstitial pneumonia and pulmonary fibrosis are still easy to diagnose, and there is no need to do so many tests. What examinations are needed should be followed by the doctor's opinion.
But the patient must be treated as soon as possible after diagnosis. Commonly used treatment methods include oxygen inhalation and drug treatment measures, and patients also need to take good care of themselves. Including proper exercise to improve immunity, it is conducive to preventing the recurrence of the disease.
