Double lung blister

Introduction Also known as wet squeaky sound, it is the sound produced by the gas through the thin secretions in the respiratory tract during inhalation. According to the size of the airway cavity and the amount of secretion, it is divided into large, medium and small blisters. Large blisters are more common in patients with bronchiectasis, tuberculosis, pulmonary edema, and coma; medium and small blisters are found in bronchial pneumonia, chronic bronchitis, and pulmonary interstitial fibrosis. Bronchopneumonia is an important common disease in infants and young children and can be caused by a variety of pathogens and other factors. It is clinically characterized by fever, cough, difficulty breathing, and fine wet rales in the lungs.

Cause

Localized wet rales in the lungs, only suggest local lesions, such as pneumonia, tuberculosis or bronchiectasis; bilateral lung wet rales, more common in heart failure caused by pulmonary blood stasis and bronchial pneumonia; The lungs are full of wet sounds, which are more common in acute pulmonary edema or severe bronchial pneumonia. There is no fixed rule of fever in children with pneumonia, but most children with pneumonia have symptoms of high fever. Individual children can have normal body temperature during the day, but they start to burn as soon as evening.

The auscultation features are intermittent and short-lived, and often appear multiple times at a time, which is more obvious when inhaling or inhaling, and the part is relatively constant.

1, fever. Clinically, children with pneumonia have no fixed fever, but most children with pneumonia have symptoms of high fever. Individual children can have normal body temperature during the day, but they start to burn as soon as evening.

2. Frequent coughing. In the early stage, it was an irritating dry cough.

3, shortness of breath. It often occurs after fever and coughing. Children often have systemic symptoms such as lack of energy, loss of appetite, irritability, mild diarrhea or vomiting.

4. Difficulty breathing. Children often have mouth and mouth, purple lips and purple, and breathing is accelerated, up to 40-80 times per minute.

Differential diagnosis

Need to be distinguished from the following symptoms:

The inspiratory burst sound of the lungs: the alveolar-capillary block syndrome, which is a group of lesions in which the alveolar-capillary wall of the gas diffusion surface is diseased and the oxygen diffusion capacity is reduced. Typical signs are mainly inspiratory bursts and clubbing of both lungs.

Pulmonary voice: The dry and wet voice of the lungs indicates respiratory diseases. Like other systemic diseases, careful detailed medical history and physical examination are the basis for diagnosing diseases. X-ray chest examination is of special importance to respiratory diseases. effect. Because respiratory diseases are often a manifestation of systemic diseases, comprehensive comprehensive analysis should be performed in combination with routine tests and other special examination results, in order to make a diagnosis of etiology, anatomy, pathology and function. The same is true for dry and wet voices in the lungs.
