Chronical bronchitis



Chronic bronchitis is a progressive, diffuse inflammation of the bronchi, not associated with local or generalized lung damage, manifested by coughing. You can talk about chronic bronchitis if the cough lasts for 3 months in 1 year 2 years in a row.

The disease is associated with prolonged irritation of the bronchi with various harmful factors (smoking, inhalation of air contaminated with dust, smoke, carbon monoxide, sulfur dioxide, nitrogen oxides and other compounds of a chemical nature) and recurrent respiratory infection (respiratory viruses, Pfeiffer's bacillus, pneumococci play a large role) occurs less frequently with cystic fibrosis.

Predisposing factors - chronic inflammatory, suppurative processes in the lungs, chronic foci of infection and chronic diseases localized in the upper respiratory tract, decreased body reactivity, hereditary factors.

The main pathogenetic mechanism is hypertrophy and hyperfunction of the bronchial glands with increased secretion of mucus, with a decrease in serous secretion and a change in the composition of the secretion, as well as an increase in acid mucopolysaccharides in it, which increases the viscosity of sputum. Under these conditions, the ciliary epithelium does not improve the emptying of the bronchial tree. In case of violation of the drainage function of the bronchi, a bronchogenic infection occurs, the activity and relapse of which depends on the local immunity of the bronchi and the occurrence of secondary immunological insufficiency. Bronchial obstruction develops due to hyperplasia of the epithelium of the mucous glands, edema and inflammatory densification of the bronchial wall, obstruction of the bronchi with excess viscous bronchial secretions, bronchospasm.
Violation of the elastic structures of the alveolar walls. In response to alveolar hypoxia, a spasm of pulmonary arterioles and an increase in total pulmonary and pulmonary arteriolar resistance develop; pericapillary pulmonary hypertension develops.

Chronic hypoxemia leads to an increase in blood viscosity, which is accompanied by metabolic acidosis, further enhancing vasoconstriction in the pulmonary circulation.

The onset of the disease is gradual. The first and main symptom is coughing in the morning with the discharge of sputum mucosa, gradually coughing begins to occur at any time of the day, intensifies in cold weather and becomes constant over the years. The amount of sputum increases, sputum becomes mucopurulent or purulent. Shortness of breath appears. With purulent bronchitis, purulent sputum may periodically be released, but bronchial obstruction is not very pronounced. Obstructive chronic bronchitis is manifested by persistent obstructive disorders. Purulent-obstructive bronchitis is characterized by the release of purulent sputum and obstructive ventilation disorders. Frequent exacerbations during periods of cold damp weather: cough, shortness of breath intensifies, the amount of sputum increases, malaise appears, rapid fatigue. Body temperature is normal or subfebrile, hard breathing and dry rales over the entire pulmonary surface can be determined.

Chronical bronchitis

  1. CHRONICAL BRONCHITIS. CHRONIC PULMONARY HEART.
    In recent years, due to the deteriorating environmental situation, the prevalence of smoking, and a change in the reactivity of the human body, there has been a significant increase in the incidence of chronic non-specific lung diseases (COPD). The term KNZL was adopted in 1958 in London at a symposium convened by the pharmaceutical group Ciba. He combined such diffuse diseases
  2. Chronical bronchitis
    Chronic bronchitis is a chronic disease characterized by diffuse inflammatory damage to the respiratory tract with excessive secretion of mucus in the bronchial tree and sclerotic changes in the deeper layers of the bronchial wall, manifested by productive cough, persistent rales of various sizes in the lungs (for 3 months), in the presence of exacerbations at least two times per
  3. Chronical bronchitis
    Chronic bronchitis is a disease common among smokers and residents of megacities affected by smog (a mixture of fog, smoke and soot). The diagnosis of chronic bronchitis is made when a persistent cough with sputum production lasts for at least 3 months in 2 years. With simple chronic bronchitis, cough with sputum without signs of airway obstruction is noted
  4. Chronical bronchitis
    Chronic bronchitis is a progressive diffuse inflammation of the bronchi, not associated with local or generalized lung damage, manifested by cough. You can talk about chronic bronchitis if the cough lasts for 3 months in the 1st year - 2 consecutive years. Etiology. The disease is associated with prolonged irritation of the bronchi by various harmful factors (inhalation of air contaminated
  5. CHRONICAL BRONCHITIS
    - diffuse inflammatory lesion of the bronchial tree, caused by prolonged irritation of the bronchi by various harmful agents, having a progressive course and characterized by impaired mucus formation and drainage function, which is manifested by cough, sputum separation and shortness of breath According to the WHO recommendation, bronchitis can be considered chronic if the patient coughs up phlegm on
  6. CHRONICAL BRONCHITIS
    On patency of the bronchi: obstructive and non-obstructive. According to the level of damage: proximal - up to 5-6 generation of bronchi. Purulent and catarrhal. Obstructive bronchitis. If distal, then the main symptom is associated with an air trap (when inhaling, the air enters the alveoli, during exhalation the bronchi are shortened, take the form of a corrugated tube and the air does not pass back, the volume increases
  7. Chronic bronchitis in children
    Protocol code: 04-042 Profile: pediatric Stage: hospital Purpose of stage: 1. clarification of the diagnosis and elimination of the inflammatory process in the bronchi; 2. relief of symptoms of respiratory failure, general intoxication; 3. FEV1 recovery. Duration: 11 days ICD codes: J40 Bronchitis, unspecified as acute or chronic J41.0 Simple chronic bronchitis J41.1 Mucopurulent
  8. Chronical bronchitis
    CHRONIC Bronchitis (CB) is a diffuse inflammatory lesion of the bronchial tree caused by prolonged irritation of the airways by volatile pollutants and / or (less commonly) damage by viral and bacterial agents, accompanied by hypersecretion of the mucus, impaired cleansing function of the bronchi, which is manifested by persistent or intermittent coughing and sputum discharge.
  9. Chronic bronchitis and emphysema
    Chronic bronchitis is a disease characterized by chronic or recurrent excessive secretion of mucus in the bronchi, leading to the appearance of a productive cough with annual exacerbations of up to 3 months or more in recent years. Emphysema is a disease caused by an increase in the air space of the end bronchioles as a result of destructive changes in their walls. Distinguish

    Chronic bronchitis is a disease characterized by chronic or recurrent excessive secretion of mucus in the bronchi, leading to the appearance of a productive cough with annual exacerbations of up to 3 months or more in recent years. Emphysema is a disease caused by an increase in the air space of the end bronchioles as a result of destructive changes in their walls. Distinguish
  11. Chronical bronchitis.
    The criterion for the diagnosis of chronic bronchitis is a productive cough for most days of three consecutive months for at least two consecutive years. In the etiology of chronic bronchitis, smoking, air pollution, occupational exposure to dust, recurrent pulmonary infections, and hereditary factors play a role. Secretion of hypertrophied bronchial glands and edema
  12. Chronic bronchitis (code J 41, J 44)
    Definition Chronic bronchitis is a diffuse, progressive non-allergic inflammatory lesion of the bronchial tree associated with prolonged irritation of the airways by harmful agents, usually characterized by a restructuring of the secretory apparatus of the mucous membrane, as well as sclerotic changes in the deeper layers of the bronchial wall and peribronchial tissue,

An important role in its development is prolonged irritation of the bronchial mucosa with chemicals, dust, and smoking. At the beginning of the disease, the mucosa is full-blooded, sometimes hypertrophied, mucous glands in a state of hyperplasia. Further inflammation extends to

    Chronic obstructive pulmonary disease is a pathological condition characterized by the formation of chronic airway obstruction due to chronic bronchitis / chronic obstructive pulmonary disease and / or pulmonary emphysema / EL /. Chronic obstructive pulmonary disease is widespread. It is estimated that HB affects about 14–20% of the male and about 3–8% of the female adult population, but only
