Croupous pneumonia

• There are the following synonyms that reflect the morphological features of lung damage: lobar, fibrinous, pleuropneumonia.

Croupous pneumonia is an infectious-allergic disease.

It is an independent nosological form. The causative agent is pneumococci of the 1st, 2nd and 3rd types, rarely - Klebsiella (Friedlander diplobacillus). In pathogenesis, an immediate hypersensitivity reaction is of great importance. Lesion of the alveoli of the entire lobe at the same time while maintaining the bronchi intact is characteristic. It is always accompanied by fibrinous pleurisy (pleuropneumonia).

Stage of lobar pneumonia.

1 Stage of the tide (microbial edema).

• 1st day: plethora of capillaries is noted, in the alveoli there is serous exudate containing a large number of microbes.

2. Stage of red guardianship.

• 2nd day.

Microscopic picture: alveoli are filled with exudate, consisting of fibrin and red blood cells.

Macroscopic picture: the affected lobe is enlarged, dense (hepatitis), red, fibrinous overlay on the pleura (fibrinous pleurisy).

3. Stage gray guardianship.

• 4th — 6th day.

Microscopic picture: capillaries start to fade, in the alveolar exudate - fibrin, white blood cells, macrophages, pleural fibrinous overlay.

Macroscopic picture: the affected lobe is enlarged, dense, granular in the section, uniform, gray.

Stage of permission.

• Day 9-11: melting and resorption of fibrinous exudate using neutrophils and macrophages.

Complications of croupous pneumonia.

1. Pulmonary.

a. Carnification (organization of exudate in the lumen of the alveoli).

b. Abscess of the lung.

in. Gangrene (wet).

2. Extrapulmonary.

• Occur with lymphogenous or hematogenous spread of the infection.

• They include purulent mediastinitis, pericarditis, peritonitis, purulent arthritis, acute ulcerative endocarditis (usually a tricuspid valve), purulent meningitis, brain abscess.


• It is manifested by the loss of a particular stage and abortive forms, a decrease in the frequency of complications.

Causes of death.

• Mortality is about 3%.

• Death occurs from acute cardiopulmonary failure or purulent complications.

Lobar Friedlepdera pneumonia.

• More often occurs as nosocomial (nosocomial) infection.

• Sick old people, newborns and patients with alcoholism.

• Necrosis of the alveolar septa with frequent formation of abscesses, foci of carnification and severe interstitial fibrosis is characteristic.

Croupous pneumonia

    This, as a rule, parenchymal pneumonia, microbial, has the usual cyclic course. It is rarely encountered at present: 10 cases of acute pneumonia account for 1 croupous, but it has retained its epidemic features. More often, adults, from 20 to 50 years old, are sick, less common in children and the elderly. Etiology: Exogenous infection; pneumococci of the first two types.
  2. Pneumonitis caused by food and vomit. Aspiration pneumonia
    ICD-10 code J69.0 Diagnosis Diagnosis Mandatory Level of consciousness, respiratory rate and effectiveness, heart rate, blood pressure, CVP, body temperature, skin condition R-graph of chest organs ECG Laboratory tests: hemoglobin, red blood cells, white blood cells, formula blood count, total protein, bilirubin, urea, creatinine, electrolytes, enzymes, blood coagulation
  3. Pneumonia Acute pneumonia.
    In pregnant women, pneumonia often proceeds more severely due to a decrease in the respiratory surface of the lungs, a high standing of the diaphragm, limiting lung excursion, and an additional load on the cardiovascular system. The clinical picture of acute pneumonia is not different from that of non-pregnant. With the development of pneumonia shortly before childbirth, development should be delayed if possible

    1. What is the synonym for croupous pneumonia: a) bronchopneumonia b) focal c) focal confluent d) segmental e) lobar Correct answer: d 2. What is the stage of croupous pneumonia? a) fibrinoid swelling The correct answer: in 3. The composition of the exudate in the 3 stages of croupous pneumonia: a) fibrin, red blood cells b) fibrin,
  5. Pneumonia
    Pneumonia is an acute infectious disease characterized by focal lesions of the respiratory departments of the lungs with intra-alveolar exudation, marked by a febrile reaction and intoxication. DIAGNOSTICS ─ Croupous pneumonia begins acutely. Sharp chills, severe headache, high body temperature, chest pain, intensifying with deep breathing, are characteristic
    Pulmonary tissue compaction syndrome. 2. A picture of chronic bronchitis. Features: a) The onset is acute, but not as stormy as with croupous. b) There are no phenomena of general intoxication and respiratory failure 3. Blood test without a large white blood cell, a small shift. 4. Localization of lung tissue. 5. The picture of concomitant bronchitis - this distinguishes focal pneumonia from
    - Acute inflammatory process of various etiologies and pathogenesis, localized in the respiratory parts of the parenchyma and in the interstitial connective tissue of the lungs. The main clinical manifestations Patients complain of cough with sputum, chest pain, shortness of breath, general weakness, fever. The nature of sputum should be considered. "Rusty" sputum is characteristic of croupous
  8. Acute inflammatory lung diseases (pneumonia)
    Among acute pneumonia, there are croupous (lobar), having the nature of an independent disease, and focal bronchopneumonia as a manifestation or complication of another disease. Croupous pneumonia is an acute infectious and allergic disease in which fibrinous inflammation seizes the lobe of the lung (lobar or lobar pneumonia) and its pleura (pleuropneumonia). Morphologically during
  9. Pneumonia
    Inflammation of the lungs in most cases refers to infectious diseases and is caused by various pathogens (pneumococci, staphylococci, streptococci, mycoplasmas, legionella, chlamydia, anaerobic microorganisms, Klebsiella, Escherichia coli, viruses, etc.). Although in recent decades, thanks to the success of antibiotic therapy, mortality from it has significantly decreased, a large
  10. Pneumonia in children
    The article “Pneumonia” is located in section 4 “Emergency conditions for respiratory diseases”. Pneumonia in children is an acute infectious disease of the pulmonary parenchyma diagnosed by respiratory distress syndrome and / or physical data, as well as by infiltrative or focal changes in the radiograph. CLASSIFICATION ¦ According to the conditions of infection, pneumonia is divided into
  11. Question 25 Pneumonia
    - An acute infectious and inflammatory disease of the pulmonary parenchyma with the involvement of all structural elements, mainly the respiratory departments of the lungs. The concept of "pneumonia" does not include lung lesions caused by physical and chemical factors, diseases caused by vascular and allergic changes, bronchitis, bronchiolitis and diffuse pulmonary fibrosis. Classification
    Croupous (abscessed) pneumonia must be differentiated from caseous pneumonia. Difficulties arise especially often with the localization of pneumonia in the upper lobes, and tuberculous lesions in the lower lobes, and are associated with the fact that in the initial period of caseous pneumonia in the sputum there are still no mycobacterium tuberculosis, and the clinical and radiological symptoms of these diseases are very similar. However should
  13. Pneumonia
    PNEUMONIA - pneumonia - a group of diseases characterized by inflammation of the parenchymal or mainly parenchymal, i.e. respiratory, parts of the lungs. They are divided into croupous (lobar) and focal. The allocation of acute interstitial and chronic pneumonia is debatable. In the domestic literature of recent years, chronic pneumonia includes recurrent pneumonia of one and the same
  14. Chronic pneumonia
    Chronic pneumonia is a chronic nonspecific bronchopulmonary process based on irreversible morphological changes in the form of deformations of the bronchi and pneumosclerosis in one or more segments and accompanied by relapses of inflammation in the lung tissue and / or bronchi. Essentially a similar definition is currently given by therapists. It is believed that under chronic pneumonia
  15. Acute pneumonia
    Acute pneumonia is an infectious disease caused by various associations of gram-positive and gram-negative microflora, a viral infection. Currently, the main pathogen is staphylococcus. D: Croupous pneumonia - acute onset, severe chills, severe headache, high body temperature, side pain, mild coughing, worse with deep breathing, severe
    Acute pneumonia is a group of acute etiological, pathogenesis and morphological characteristics of acute infectious inflammatory diseases of the lungs with a primary lesion of the respiratory departments and the presence of intra-alveolar exudate. Most commonly caused by bacteria, mycoplasmas and viruses. According to clinical and morphological features, croupous (lobar) pneumonia is distinguished,
  17. Pneumonia
    PNEUMONIA (Mon) - an acute infectious lesion of the lower respiratory tract, confirmed radiologically, dominant in the picture of the disease and not associated with other known causes. The definition of Mon emphasizes the acute nature of inflammation, so there is no need to use the term "acute pneumonia" (in the International Classification of Diseases, adopted by the World Organization
  18. Question 26. Pneumonia (pneumonia)
    - This is an acute infectious disease, which is characterized by damage to lung tissue, diagnosed by respiratory distress syndrome and physical data in the presence of focal or infiltrative changes in the radiograph. The form of pneumonia depends on the virulence of the pathogen, the level of specific immunity and the characteristics of the body's reactivity. Classification Pneumonia can be
    largely due to the type of pathogen, the characteristics of pathogenesis, the prevalence of the inflammatory process and the state of the macroorganism. Lobar pneumonia It is the most severe form of pneumonia. It occurs in almost 5% of cases among all acute pneumonia, characterized by lobar or segmental damage to the lung and involvement of the pleura.
    Pneumonia is an acute infectious disease characterized by focal lesions of the respiratory parts of the lungs with intra-alveolar exudation, detected by objective and x-ray examination, expressed to varying degrees by a febrile reaction and intoxication. Clinically significant is the division of pneumonia into community-acquired and nosocomial (hospital,
