How to check pneumonia in children

There are certain standards for pneumonia examinations. Since the symptoms of pneumonia are similar to those of common colds, we should not underestimate pneumonia examinations and should be more careful. For example, fever, cough, shortness of breath, etc. are only the most basic and most common tests for pneumonia. In addition to these, there are some more accurate methods for pneumonia examinations. The following are a few methods of pneumonia examinations that we all need to know:

1. The disease occurs 48 hours after admission, with symptoms of cough, sputum, or changes in sputum characteristics.

2. Fever, lung rales, or new inflammatory lesions compared with X-rays at admission.

3. Screened sputum is one of the diagnostic bases for pneumonia.

4. Blood culture is positive or pneumonia is complicated by pleural effusion and pathogens are isolated through puncture and fluid aspiration.

5. The diagnosis of pneumonia also requires analysis of contaminating bacteria.

6. Special pathogens are detected in respiratory secretions or confirmed by immunological methods in respiratory secretions, serum and other body fluids, or there is histopathological evidence.

7. Routine blood test is also one of the examination methods for pneumonia, which includes the total number of white blood cells and the percentage of various white blood cells in the total white blood cells. The total number of white blood cells in a normal person is 4~10×109/L, and the percentage of neutrophils is less than 70%. If the total number of white blood cells exceeds 10×109/L and the percentage of neutrophils exceeds 70%, we say that the patient's blood count is high, which is a common blood count change in bacterial pneumonia. This type of pneumonia examination is relatively common.

8. X-ray chest examination: By performing X-ray chest examination on patients, we can directly understand the changes in the lungs. It is the main measure in the examination of pneumonia.

9. Testing of humoral immunity.

10. Liver function test and kidney function test.

11. Specific allergens can be detected by radioallergen adsorption test (RAST) to measure specific IgE. The serum IgE of patients with allergic asthma can be 2 to 6 times higher than that of normal people. This is also a pneumonia examination item.

12. Blood gas analysis: Severe asthma attacks may cause hypoxia, decreased PaO2 and SaO2, and excessive ventilation may cause decreased PaCO2 and increased pH, indicating respiratory alkalosis. This is also one of the examination methods for pneumonia.

13. Endoscopic examination.

Mistakes in pneumonia examinations can lead to many consequences. In addition to delaying treatment for patients, there is also the possibility of choosing the wrong treatment plan, which can endanger the patient's life safety. This is something that needs to be taken seriously. Therefore, we all need to learn more about pneumonia.
