Tuberculous pleural effusion can be closed drainage, but it should be decided according to the specific amount of fluid. In the clinic, closed thoracic drainage is mostly used for the treatment of pneumothorax, for the pleural effusion caused by tuberculosis, if it is medium to large amount of effusion, then it is necessary to carry out closed thoracic drainage, and the basic treatment principle is to drain the effusion cleanly and reduce the adhesion of the pleura, and the therapeutic effect will be better. However, if the amount of tuberculous pleural effusion is relatively small, closed pleural drainage is not necessary, on the one hand, because the amount of effusion is relatively small, and can be absorbed through active anti-tuberculosis treatment, on the other hand, closed pleural drainage is an invasive operation, and the drainage tube as a foreign body will irritate the pleura, which is more detrimental than beneficial. Whether or not closed drainage is needed for tuberculous pleural effusion needs to be evaluated by a specialized physician, and it is recommended that patients with tuberculous pleural effusion consult a doctor in time in order to obtain a good therapeutic effect.
