Sequelae of lobar pneumonia

Lobar pneumonia often occurs in young and middle-aged men. Common causes of the disease include catching a cold, being tired or getting caught in the rain. Generally, lobar pneumonia will usually be cured after active treatment without leaving any sequelae. Since the body has established a strong immunity after the infection, secondary infection with the same type of bacteria is rare. However, if you are unlucky enough to have sequelae, then we must have a thorough understanding of lobar pneumonia.

The prevention of pneumonia generally involves avoiding triggering factors such as getting wet in the rain, catching cold, fatigue, and drunkenness. For the elderly, the weak and the immunocompromised, such as patients with chronic liver disease, diabetes, and splenectomy, pneumonia vaccination can be given

1. Concept: An acute inflammation mainly caused by pneumococcus that affects most or all of the lung lobes and is characterized by diffuse fibrin exudation in the alveoli.

2. Etiology and pathogenesis

Pneumococcus is not caused by phagocytosis of the pneumococcus or clearance by mucus ciliary cells. It is generally believed that allergic factors play an important role in the inflammatory response of lung tissue to bacteria invading the alveoli. Some pneumococci with weaker toxicity can exist in the upper respiratory tract for a long time, making the body allergic to the bacteria.

3. Complications

(1) Pulmonary cartilage degeneration: There is more cellulose in the alveolar cavity, less neutrophil infiltration, and insufficient lysozyme. As a result, the cellulose exudates in the alveoli cannot be completely decomposed, absorbed and cleared, and are then ossified by granulation tissue. The diseased lung tissue becomes brown meat-like fibrous tissue.

(2) Purulent pleurisy and empyema

(3) Lung abscess: Very rare, seen in infections with highly virulent pathogens, type 3 pneumococcus, or mixed infections with Staphylococcus aureus.

(4) Sepsis or sepsis

(5) Septic shock: the most serious complication, more common, and with a higher mortality rate.

Everyone should try to be careful, because the weather conditions are sometimes good and sometimes bad, and there are more and more particulate matter in the air. Most people who get this disease start with a respiratory infection, and no one would have thought that there would be such consequences. Therefore, everyone should pay attention to maintaining hygiene and health in their daily life. We can’t control the air, but we should at least pay attention to our daily life patterns. Take your health into consideration and further protect your health.
