Pleural fluid caused by tuberculous pleurisy is exudate, turbid in appearance, with high protein content, high cell count, and predominantly lymphocytes, and is prone to cause pleural adhesions. For the pleural fluid caused by tuberculous pleurisy, in principle, the fluid in the chest cavity should be pumped out as soon as possible, or to be closed drainage by thoracocentesis, to relieve the compression of the heart and lungs, after pumping the fluid can alleviate the symptoms of toxicity of tuberculous pleurisy, so that the body temperature drops, so that the compressed lungs are reexpanded. There is no need to inject anti-tuberculosis drugs into the chest cavity after fluid extraction, and generally oral anti-tuberculosis drugs are administered for a period of 6-9 months.
