Category Disease | December 12, 2017 00:03

Emphysema of lungs is a disease of the respiratory tract, characterized by the development of the pathological process in the lungs, which causes a strong expansion of the distal bronchioles, accompanied by a violation of the gas exchange and the development of respiratory failure.

To date, the incidence of this disease has increased significantly, and if earlier it was found mainly among persons of retirement age, today people aged 30 years old are affected by it( men with emphysema are twice as likely to get sick).Moreover, the disease( in combination with asthma and obstructive bronchitis) belongs to the group of chronic lung diseases that have a progressive course, often become the cause of temporary disability of the patients or lead to their early disability. At the same time, such a disease as emphysema of the lungs is characterized by the fact tha

t it can be accompanied by a fatal outcome, so everyone should know its symptoms and the basic principles of treatment.

Etiology, pathogenesis and varieties of the disease

Emphysema of the lungs

One of the characteristics of emphysema of the lungs is that as a separate nosological form it occurs only in a small percentage of patients. In most cases, emphysema is a final pathological process that occurs against the background of severe morphological lesions of the bronchopulmonary system, which manifest themselves after such diseases as:

  • tuberculosis;
  • silicosis;
  • obstructive bronchitis;
  • bronchiectatic disease;
  • pneumonia;
  • bronchial asthma;
  • anthracosis.

In addition, emphysema of the lungs can be caused by prolonged smoking or inhalation of some toxic compounds of cadmium, nitrogen or dust particles that are floating in the air( for this reason this disease is often found in builders).

Mechanism for the development of the disease

Under normal conditions, gas exchange in the human body takes place in the alveoli - these are "small bags" pierced by a large number of blood vessels located at the end of the bronchi. During the inhalation, the alveoli are filled with oxygen and swell, and when exhaled, they contract. However, with emphysema of the lungs, certain abnormalities occur in this process - the lungs are stretched too much, their tissue becomes denser and loses its elasticity, which leads to an increase in the concentration of air in the lungs and causes a disruption in their functioning. With the passage of time, emphysema of the lungs progresses, which manifests itself in the development of respiratory failure, so it is necessary to start treating it as early as possible.

Classification of the disease

Depending on the causes that lead to the development of the pathological process in the pulmonary tissue, lung emphysema is classified into:

  • primary( diffuse), which causes tobacco smoke, dust or inhalation of nitric oxide - is characterized by a loss of elasticity of the lung tissue, a morphological change in the respiratorydepartment of lungs and increased pressure in the alveoli;
  • secondary( obstructive) - occurs against a background of stretching of the alveoli and respiratory bronchioles caused by obstruction of the airways;
  • vicar - it is a kind of compensatory reaction of one lung to some changes( and sometimes the absence) of another, as a result of which a healthy lung increases in volume, but only in order to ensure a normal gas exchange in the human body( the vicarious emphysema of the lungs only occurswithin one lung and is not considered a pathological process, the prognosis is favorable).

There is also bullous emphysema of the lungs, which is characterized by the fact that it proceeds imperceptibly, is often found already at the stage of pneumothorax( accumulation of air in the pleural cavity) and requires immediate surgical intervention, the prognosis of development is unfavorable( often leads to the patient's death).

Smoking and emphysema of the lungs

Clinical picture of the disease

When talking about the main symptoms of emphysema of the lungs, doctors first of all mention:

  • shortness of breath;
  • visual increase( expansion) of the chest on the background of a decrease in her excursion during breathing( emphysema can be determined from the photo, which shows that the chest is in a phase of deep inspiration);
  • cyanosis( blue hue) of the tongue, nails and lips, occurs against the background of oxygen starvation of tissues;
  • expansion of intercostal spaces;
  • anti-aliased areas.

At the very beginning of emphysema of the lungs manifested by shortness of breath, which first arises during sports( mainly in the winter) and is characterized by inconsistency, and then disturbs the person at the slightest physical effort. Characteristic signs of the disease include the fact that patients make short breaths with closed lips and inflated cheeks, and also pay attention to the fact that during the inspiration, the muscles of the neck are involved( in the normal state this should not be).Also, emphysema is accompanied by coughing, chest pain and weight loss( the latter is explained by the fact that patients spend too much energy on maintaining the normal functioning of the respiratory muscles).

Patients often occupy the forced position of the body on the abdomen( the head is lowered down), because this position brings them relief, but this is in the first stages of the disease. As the emphysema of the lungs develops, changes in the chest prevent patients from being in a horizontal position, as a result of which they even sleep in the sitting position( this facilitates the work of the diaphragm).

Basic methods for diagnosis of emphysema of the lungs

Diagnosis of pulmonary emphysema should be exclusively handled by a pulmonologist who makes a primary diagnosis based on patient examination and auscultation of pulmonary breathing using a phonendoscope. These are the main diagnostic methods, but they do not allow to make a complete clinical picture of the disease, therefore,

  • lung X-rays( shows the density of lung tissue) are used as additional methods of investigation;
  • computed tomography( considered one of the most accurate methods of diagnosing emphysema of the lungs);
  • spirometry( examination of the function of breathing, to determine the degree of disruption of the lungs).

How to treat?

The main methods of treatment of emphysema are as follows:

  • quitting( this is a very important issue that doctors pay special attention to, since if the patient does not quit smoking, then it will be impossible to cure the emphysema of the lung, even with the help of the most effective medicines);
  • oxygen therapy( designed to saturate the patient with oxygen, since the lungs can not cope with this function);
  • gymnastics( breathing exercises "strengthens" the work of the diaphragm and helps to get rid of shortness of breath, which is the main symptom of emphysema of the lungs);
  • conservative treatment of concomitant diseases( bronchial asthma, bronchitis, and so on), causing emphysema, the symptoms of which are determined by the doctor;When joining the infection to the main treatment of emphysema, antibiotics are added.
Oxygen therapy

Surgical treatment of emphysema of the lungs is indicated only if the disease occurs in the bullous form, and it boils down to the removal of bullae - air-filled thin-walled blisters that can be localized in any part of the lung( it is almost impossible to see them in the photo).The operation is performed by a classical and endoscopic method. The first method involves surgical opening of the chest, and during the second the surgeon conducts all necessary manipulations with the help of special endoscopic equipment through small incisions on the skin. The endoscopic method of removing bullae in emphysema of the lungs will cost more, but this operation has a shorter rehabilitation period.

The main number of conservative methods of treatment of this disease is not very effective, because unlike bronchitis, lung emphysema causes irreversible structural changes in the pulmonary tissue. The prognosis depends on the timeliness of the treatment started, the observance of the doctor's recommendations and the correctly selected method of drug therapy for both primary and secondary diseases.

In any case, the treatment of emphysema of the lungs should only be dealt with by a doctor. The disease is considered chronic and the patient has to take lifelong medications that support the basic functions of the respiratory system. Life expectancy of people with emphysema depends on the degree of damage to the lung tissue, the age of the patient and the individual characteristics of his body.

Mitral stenosis( stenosis of the mitral valve)( coinciding symptoms: 4 of 8)

Mitral stenosis or stenosis of the mitral valve is a dangerous disease of the cardiovascular system. The pathological process leads to a violation of the natural outflow of blood from the left atrium to the left ventricle. In other words, the hole between them narrows. In the main risk group, women aged 40-60 years. But the male half of the population is also susceptible to this type of cardiovascular disease. According to statistics, the disease is diagnosed in 0.5-0.8% of the total population of the planet.

Thromboembolism( coinciding symptoms: 4 of 8)

Thromboembolism or thromboembolic syndrome is not a single disease, but a symptom complex that develops when a blood clot forms in a vessel or drifts a blood clot, lymph, or air in them. As a result of this pathological condition, heart attacks, strokes or gangrene develop. Thromboembolism can affect vessels of the brain, heart, intestines, lungs or lower limbs.

Coronary insufficiency( coinciding symptoms: 3 of 8)

Coronary insufficiency is a pathological condition in which coronary blood flow is partially reduced or completely stops. As a consequence, the heart muscle will receive an insufficient amount of nutrients and oxygen. This condition is the most common manifestation of IHD.Most often, acute coronary insufficiency is behind a heart attack of the heart muscle. Sudden coronary death is also directly related to this pathological process.

Ascites( coinciding symptoms: 3 of 8)

Ascites of the abdominal cavity( known as hydrocele) is a pathology that is a complication of other diseases. Ascites of the abdominal cavity is characterized by the formation and subsequent accumulation of fluid inside the abdomen, which worsens the functioning of the organs in the cavity of the peritoneum. Code for the International Classification of Diseases ICD-10: R18.Such a disease requires immediate intervention of specialists performing paracentesis at a high level and prescribing a special diet. Often, laparocentesis is used to treat the disease.

Fibrosis of lungs( coinciding symptoms: 3 of 8)

Fibrosis of the lungs is a disease that involves the presence of tissue in the lungs of scar tissue that disrupts the function of breathing. Fibrosis lowers the elasticity of the tissues, which makes the passage of oxygen through the alveoli( bubbles where the air contacts the blood) more difficult. This disease involves the replacement of normal lung tissue with connective tissue. Reverse process of regeneration of connective tissue again in the pulmonary is not possible, so the patient can not fully recover, however, it is still possible to improve the patient's quality of life.
