LUNG ADENOMATOSIS

Chronic, long-running viral disease of sheep, cattle, horses and dogs, characterized by progressive metaplasia of the bronchial and alveolar epithelium, proliferation in the lungs of glandular tumors, becoming malignant. Adenomatosis of the lungs also affects a person.

The causative agent is a filtered virus.

Pre-slaughter diagnostics. Clinically, the disease manifests itself in the last stages and is accompanied by severe shortness of breath, which is especially noticeable during the passage of animals.

Post-mortem diagnosis. The mucous membrane of the larynx and trachea is swollen and cyanotic. In the lungs, limited or spilled foci of dense consistency, grayish-white or grayish-pink, are found. From the surface, the lesion centers are as if slightly sunken. When the lungs are cut, a clear foamy liquid flows from small and large bronchi, sometimes in the form of viscous mucus. Bronchial and mediastinal lymph nodes are enlarged, tight to the touch, muddy lymph is released from the surface of their incision.

Differential diagnosis.
With the differentiation of adenomatosis and diseases similar to it, it is necessary to exclude verminous pneumonia of diktiocaulic origin, lung atelectasis (usually the apices), resulting from lung inactivity in the postnatal period, catarrhal and other pneumonia resulting from second infection (ornithosis, salmonellosis, chronic pasteurellosis )

Veterinary sanitary assessment. When establishing lung adenomatosis, the release of meat and other products in raw form is prohibited.

The carcasses of exhausted animals, together with their heads and internal organs, are directed to the production of meat and bone meal, which is then fed only to the bird.

Carcasses and internal organs without apparent pathological changes obtained from the slaughter of patients and animals that are seropositive for the virus are sent to the manufacture of cooked and cooked smoked sausages, to meat bread or canned goods.

The head, bones, lungs and other pathologically altered organs, as well as the gastrointestinal tract, are sent for disposal. The skin and wool are disinfected.

  5. Regular ventilation regimen with intermittent inflation
    It is well known that monotonous tidal volume during mechanical ventilation increases uneven ventilation of the lungs and contributes to their atelectasis. Indeed, even with independent breathing, a healthy person never breathes the same respiratory volume, the latter is constantly changing. In addition, a healthy person periodically takes "sighs" of increased volume and duration. To overcome
  6. Artificial ventilation of the lungs during operations on the lungs and mediastinal organs
    One-lung ventilation. A necessary condition for lung operations - switching off the operated lung from ventilation according to absolute (wet lung, pulmonary bleeding, leaky lung) or relative indications - puts the body in non-physiological conditions of functioning, leads to impaired gas exchange and blood circulation. However, a technique widely used in thoracic surgery
  7. Acute left ventricular failure - interstitial and alveolar pulmonary edema. Non-cardiogenic pulmonary edema.
    Cardiogenic and non-cardiogenic pulmonary edema are considered as the immediate cause of death in every fourth person who died. Pathogenesis. In a healthy person, the hydrostatic pressure in the pulmonary capillaries is 7–9 mm Hg. Art., it slightly exceeds that in interstitium. The liquid is retained in the capillaries due to its viscous properties, sufficiently high figures of oncotic
  8. EXTERNAL RESPIRATION AND FUNCTIONS OF THE LUNG RESPIRATORY FUNCTION OF LUNG AND PATHOPHYSIOLOGICAL MECHANISMS OF HYPOXEMIA AND HYPERCAPNIA
    The main function of the lungs - the exchange of oxygen and carbon dioxide between the environment and the body - is achieved by a combination of ventilation, pulmonary circulation and diffusion of gases. Acute violations of one, two or all of these mechanisms lead to acute changes in gas exchange. Pulmonary ventilation. Indicators of pulmonary ventilation include tidal volume (Vt), respiratory rate (f), and minute volume

    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
  10. Ventilation-induced pulmonary edema, lung damage, and “volume trauma” (volume trauma)
    Pathogenesis Even in the absence of an alveolar rupture, the use of excessive regional volumes undoubtedly damages the alveoli, regardless of whether the introduction of such volumes is caused by positive or negative pressure. Patients with acute respiratory distress syndrome appear to be at the highest risk: the prevalence of barotrauma under these conditions can exceed 50%. At
  11. Correction methods for acute respiratory failure in acute lung injury / acute respiratory distress syndrome with a proven effect on mortality and fan-induced lung damage
    • ???? Ventilation with small tidal volumes. The use of small tidal volumes can reduce the manifestations of volumotrauma and avoid high transpulmonary pressures. According to the largest multicenter randomized controlled trial conducted by ARDSnet in 41 centers and involving 861 patients, the use of small tidal volumes (6 ml / kg body weight) leads to

    Pneumoconiosis - x-x development of fibrotic changes in the lungs as a result of prolonged inhalation of the industry. dust. According to the etiology, 6 groups of PCs are distinguished: 1) silicosis-PC from inhalation of silica dust (silicon oxide) 2) silicotosis-PC from inhalation of silica dust, soda-silica in a bound state with other elements # astestosis, talcosis. 3) metallokoniosis - PC from dust Me: Al - aluminum, iron oxides - siderosis. four)
  13. Barotrauma of the lungs
    Barotrauma in mechanical ventilation - damage to the lungs caused by the action of increased pressure in the airways. Two main mechanisms causing barotrauma should be pointed out: 1) over-bloating of the lungs; 2) uneven ventilation against the background of an altered lung structure. With barotrauma, air can enter the interstitium, mediastinum, neck tissues, cause pleural rupture and even penetrate into the abdominal cavity.

    Barotrauma in mechanical ventilation - damage to the lungs caused by the action of increased pressure in the airways. Two main mechanisms causing barotrauma should be pointed out: 1) over-bloating of the lungs; 2) uneven ventilation against the background of an altered lung structure. With barotrauma, air can enter the interstitium, mediastinum, neck tissues, cause pleural rupture and even penetrate into the abdominal cavity.
  15. Lung features
    Lungs in children, as in adults, are divided into lobes, lobes into segments. The lungs have a lobed structure, segments in the lungs are separated from each other by narrow grooves and septa from connective tissue. The main structural unit is the alveoli. Their number in a newborn is 3 times less than in an adult. Alveoli begin to develop from 4-6 weeks of age, their formation
  16. Restrictive lung disease
    Causes of restrictive pathology of the lungs Causes of acute restrictive pathology: • ???? pulmonary edema; • ???? ARDS; •????aspiration; • ???? neurogenic edema; • ???? overdose of opioids; • ???? congestive myocardial failure; • ???? pleural effusion; •????pneumothorax; • ???? an increase in the mediastinum; • ???? pneumomediastinum.

  17. Vascular pathology of the lungs.
    Vascular pathology of the lungs occurs in various diseases of the lungs, heart and blood vessels, liver and is described by a variety of syndromes. The most important options for vascular pathology of the lungs are represented by the following groups of diseases: pulmonary edema; adult respiratory distress syndrome; pulmonary embolism syndrome; syndromes of primary and secondary pulmonary hypertension;
  18. Restrictive lung disease
    Restrictive diseases are characterized by a decrease in lung distensibility. Pulmonary volumes are below normal, while the volumetric flow rate on the exhale is not reduced. Thus, FEV1 and FVC are reduced, but the ratio of FEVc / FVC remains normal. Restrictive diseases include many acute and chronic pathological conditions of the lungs, as well as lesions of the pleura, chest wall, diaphragm and
  19. Atelectasis of the lungs.
    Atelectasis is a pathological process characterized by reversible incomplete expansion or collapse of a previously contained part or whole lung. The following types of atelectasis are distinguished: 1. Resorption (obstructive) atelectasis that occurs with complete obstruction of the bronchial tree with obstructive pulmonary diseases, foreign body aspiration, and tumor growth. 2. Compression atelectasis
  20. Pulmonary edema
    Pulmonary edema is a pathological increase in the volume of extravascular fluid in the lungs. The main role is played by an increase in hydrostatic pressure in the pulmonary vessels, a decrease in the plasma COD, and an increase in the permeability of the vascular wall. In 1896, E.G. Starling substantiated the theory of vascular resorption of fluid from connective tissue spaces into small vessels, according to which Qr = K (deltaR -
