Differentiation of aspiration pneumonia in the elderly

Senile pneumonia sometimes needs to be differentiated from the following diseases.

1. Heart failure

In the early stage of left heart failure, there are coughing, coughing up pink foamy sputum and so on. However, it has difficulty breathing, more prominent palpitation, cannot lie down, dense moist rales at the bottom of both lungs, PaO2 is significantly lower, PaO2 is normal or lower, and most of them have a history of heart disease and are different from pneumonia.

2. Pulmonary embolism

Patients with pulmonary embolism often have fever, cough, hemoptysis, and shortness of breath, but their onset is sudden and chest pain is obvious. The electrocardiogram often shows SⅠQⅡTⅢ dynamic and typical changes and V1~2T wave inversion, pulmonary P wave, and right bundle branch block. In pneumonia. If necessary, radionuclide lung ventilation/perfusion scan is performed for identification.

3. Tuberculosis

Obvious shadows can be seen on fever, cough, sputum, and chest X-ray. Generally, patients with poor anti-infective treatment should consider the possibility of tuberculosis. Careful tracing of the medical history, the presence of old tuberculosis foci on chest X-rays, increased lymphocytes, sputum tuberculosis test, tuberculin test, polymerase chain reaction (PCR) test, etc. help to identify.

4. Other

Patients with gastrointestinal symptoms should be distinguished from acute gastroenteritis; shock pneumonia should be distinguished from shock caused by other causes.
