Segmental or lobar indistinct opacities around the lower lobes of the lungs
Introduction
Introduction Examination often found that the segmental or large-leaf blurred shadow around the lower lobe is the result of x-ray examination of lobar pneumonia. Large lobar pneumonia lesions begin in the local alveoli and spread rapidly to a segment of the lung or the entire lobules. Clinically, the onset is rapid, the course of disease is about one week, often starting with high fever and aversion to cold, followed by chest pain, cough, cough and rust, difficulty breathing, and signs of lung consolidation and increased white blood cell count in peripheral blood.
Cause
Cause
Common causes include cold, rain, drunkenness or general anesthesia, and excessive sedatives.

Diagnose based on:
1. The disease occurs in young men and winter and spring and spring.
2. There are many incentives before the onset of illness. About half of the cases have pre-existing manifestations such as upper respiratory virus infection.
3. Sudden onset of chills and high fever.
4. Cough, chest pain, shortness of breath, rust and rust. Severe patients can be accompanied by shock.
5. Physical signs of the lungs. In severe cases, blood pressure often drops below 10.5/6.5KPa (80/50mmHg).
6. The total number of white blood cells increased, neutrophils reached 0.80 or more, and the nucleus moved to the left, with poisonous particles.
7. A large number of Gram-positive cocci are visible in the smear.
8. , blood culture has pneumococcal growth.
9. Serological test positive (cooperative agglutination test, convective immunoelectrophoresis detection of pneumococcal capsular polysaccharide antigen).
10. Chest X-ray examination showed a large patchy density with uniform segment or leafiness.
11. Blood gas analysis showed a decrease in PaO2 and PaCO2, and PaCO2 in patients with chronic obstructive pulmonary disease increased.
Diagnosis
Differential diagnosis
Lobular pneumonia: Cough due to stimulation of the bronchial mucosa often causes mucus purulence. Because the lesions are often small and scattered, the signs of lung consolidation are generally not obvious. The bronchioles and alveoli in the lesion area contain exudate, and the auscultation can smell wet rales. X-ray examination showed that the lungs were scattered in small pieces or spots.
