What's the matter with localized dullness in chest percussion

summary

The pulmonary signs of patients with pulmonary tuberculosis vary according to the severity of the disease and the scope of the disease. It is not easy to find positive signs in early and small-scale tuberculosis in the hospital. In patients with a wide range of disease, there are dullness, increased speech tremor, low alveolar breathing sound and moist rales in percussion. In the late stage of tuberculosis, the pleural collapse and mediastinum displacement were caused by local contraction. In the early stage of tuberculous pleurisy, pleural fricative sound was found. When a large amount of pleural effusion was formed, the chest wall was full, the percussion was turbid and solid, and the voice tremor and breath sound were reduced or disappeared. Now let's learn how to deal with the limited voiced voice of chest percussion.

What's the matter with localized dullness in chest percussion

First: pulmonary tuberculosis cough is mostly dry cough or cough white sticky phlegm, more systemic toxic symptoms, such as afternoon low fever, night sweat, fatigue, weight loss, insomnia, palpitations, female patients can have menstrual disorders or amenorrhea, and pneumonia is acute onset with fever, cough, expectoration obvious

Second: can also go to the hospital to do a chest film, tuberculosis X-ray chest film see lesions in the apex of the lung or clavicle, uneven density, slow dissipation, and can form a cavity or pulmonary dissemination. Mycobacterium tuberculosis can be found in sputum. General antibacterial treatment is ineffective. Pneumonia chest X-ray showed light and uniform patchy or patchy shadow, body temperature dropped rapidly after antibacterial treatment, shadow had obvious absorption about 1-2 weeks.

Third: sputum Mycobacterium tuberculosis examination is the main method for the diagnosis of pulmonary tuberculosis. Fiberoptic bronchoscopy is used for the diagnosis of bronchial tuberculosis and lymph node sputum. Tuberculosis diagnosis of children, adolescents and young people can go to the hospital for tuberculin test

matters needing attention

Diagnostic treatment is helpful to diagnosis. If anti infective treatment is ineffective and chest CT examination has no obvious absorption change, anti tuberculosis treatment can be carried out. If the condition gradually improves, the treatment of pulmonary tuberculosis should also be considered.
