Hemoptysis, bronchiectasis, pulmonary tuberculosis and lung cancer are the most common common diseases. Are there symptoms of infection, poisoning, purulent sputum, infection, septic shock and chronic lung abscess? Lobar pneumonia: When the body suffers from cold, excessive fatigue, drunkenness, cold, diabetes and low immune function, the defensive function of respiratory tract is weakened. Bacteria invade alveoli. Through allergic reaction, the capillary permeability of alveolar wall is enhanced, serum and cellulose are exuded. Bacteria in protein-rich exudates multiply rapidly and spread to adjacent lung tissues through alveolar pores or bronchioles. It extends to one lung segment or the whole lung lobe. The exudate of the interlobular spreading freshwater fungus was disseminated through the lobar bronchus.
Lobar pneumonia is an alveolitis caused by Streptococcus pneumoniae infection in a lobe or segment of the lung. Typical lobar pneumonia has been rare in recent years due to the use of a large number of powerful antibiotics. Usually when the climate changes abruptly and the body's resistance decreases. Winter and spring are common, mainly in children over 3 years of age, so when the body's immune function is gradually mature, it can make the lesion confined to a lobe or a segment of the lung without spreading. Generally, lobar pneumonia has an acute onset, characterized by sudden high fever, chest pain, loss of appetite, fatigue and irritability. A few children may have abdominal pain, sometimes misdiagnosed as appendicitis. Severe children develop symptoms of toxic encephalopathy, convulsions, delirium and coma, or even septic shock.
2. Caseous pneumonia: with a history of tuberculosis, slow onset, normal white blood cell count. Mycobacterium tuberculosis can be found in sputum. X-ray examination of the lungs may have cavity formation.
3. Secondary infection of lung cancer: older, slow onset, no obvious symptoms of poisoning, persistent phlegm with blood, X-ray examination and fiberoptic bronchoscopy or
