Pneumonia is inflammation of the terminal airways, alveoli and lung interstitium, and bacterial pneumonia is the most common.
Classification of pneumonia
Anatomical classification: lobular pneumonia, lobular pneumonia, interstitial pneumonia.
Etiological classification: bacterial pneumonia, viral pneumonia, fungal pneumonia, pneumonia caused by atypical pathogens, pneumonia caused by other pathogens.
Classification of disease environment: community acquired pneumonia, hospital acquired pneumonia.
1,Streptococcus pneumoniae pneumonia
Pneumonia caused by infection with streptococcus (think of streptococcus as a chain connected by balls); Lobar pneumonia is a common type of community-acquired pneumonia. Before the onset of often cold rain, fatigue, drunk and other inducements; Have fever, chest pain, cough rusty sputum (iron chain is rust color) symptoms. Severe symptoms can cause shock; X – ray: large inflammatory infiltration and consolidation (a large bruise can form when hit by a chain); Streptococcus depends on the capsule to cause disease, the capsule does not secrete toxins, so it does not cause lung tissue necrosis, lung tissue after the dissipation of the disease is normal; Penicillin is the treatment of choice.
It’s pneumonia caused by staphylococcus aureus infection. It is a common type of hospital – acquired pneumonia. Have high fever, chest pain, cough yellow purulent sputum (after eating a golden grape spit out) symptoms; X-ray examination: lung cavity, fluid balloon cavity (a complete grape skin is a cavity, half a grape is a cavity with liquid and gas); Pathogenic substances are mainly toxins and enzymes that destroy lung structure. Semisynthetic penicillin and cephalosporins are the first choice for treatment.
It is the main pathogenic bacteria of hospital acquired pneumonia. (Remember Crabbe is a brick-burner); There are high fever, cough, cough brick red, gelatinous phlegm (Klebber is brick burning) symptoms; The exudate in the lesion is thick and heavy, often causing the gap to fall (because the brick is heavy). X-ray: a honeycomb abscess (the inside of the brick is honeycomb); Aminoglycoside antibiotics for treatment.
Mycoplasma floats in the air and becomes infected when inhaled. The incubation period is usually 2-3 weeks (because the mycoplasma is relatively small, inhalation of the respiratory tract through the alveoli directly into the lung interstitium, initially no symptoms, the lung interstitium accumulation to a certain extent will have symptoms). Cough for episotic irritant cough; Condensation set test positive; Serum mycoplasma IgM antibody positive; X-ray examination: interstitial pneumonia in the lower lobe of the lung, with patchy shadows with blurred edges. Erythromycin was the first choice for treatment.
The common virus is influenza virus, the onset of seasonal; Mostly interstitial pneumonia, lung fibrosis can be left after the absorption of lesions; Systemic poisoning symptoms, no obvious signs; X-ray examination: increased lung texture, small or extensive infiltration; The diagnosis depends on etiological examination to see whether it is caused by influenza virus; The treatment is mainly symptomatic treatment.
