If the patient is diagnosed with pleural effusion due to pleurisy, it is necessary to actively improve the pleural puncture test, and at the same time improve the PPT test, ESR, screening of anti insect bacteria and other related tests. If the patient has anti insect bacilli in sputum or pleural fluid, it can be definitely diagnosed as active pulmonary tuberculosis or tuberculous pleurisy.? Systematic anti tuberculosis treatment includes isoniazid, rifampicin and streptomycin. At the same time, we should pay attention to the side effects of anti tuberculosis drugs, such as liver function damage, peripheral neuropathy, renal function damage, vision damage, auditory nerve damage and so on, and make corresponding symptomatic treatment.
