The treatment of effusion in the lungs depends on the cause of the effusion in the lungs. The most common clinical cause is some inflammatory reaction in the lung, such as tuberculosis caused by Mycobacterium tuberculosis infection, which causes pleurisy resulting in tuberculous pleural effusion. At this time, the main treatment is to give active anti-tuberculosis bacillus treatment, and you can choose isoniazid, rifampin, ethambutol, pyrazinamide, streptomycin, levofloxacin and other drugs to standardize the treatment. The other is the relatively rare cancerous pleural effusion caused by lung cancer, which needs to be actively treated with early surgery and supplemented with radiotherapy and chemotherapy. Symptomatic treatment is mainly aimed at extracting the fluid from the lungs when the fluid accumulation is too much, which will compress the lungs and affect the respiratory function of the lungs, resulting in difficulty in breathing, so thoracentesis can be chosen.
