The side effects of lung scaling include but are not limited to reduction of lung surface active substances, transient pulmonary edema, etc., which can usually be gradually relieved on their own, and there is usually no after-effects if the operation is standardized. Lung cleaning is one of the most commonly used treatments for pneumoconiotics. Lung cleaning can effectively improve lung function, remove impurities (sputum, tuberculosis bacilli) in the alveoli, reduce the number of respiratory infections, remove tuberculosis foci on the lungs, reduce the spread of tuberculosis, and shorten the course of tuberculosis treatment. The side effects of lung washing are: 1. Decrease of active substances on the surface of the lungs: lung cleaning will take away a small part of the active substances secreted on the surface of the alveoli, which are produced by the lungs themselves, and they are usually transient and will recover on their own. 2. Transient pulmonary edema: during the process of lung scaling, there will be transient pulmonary edema, but this is mild, has no effect on the normal lung function, and will not lead to dyspnea, and can be recovered in a short time. Lung scaling side effects may also have anesthesia accident, infection, respiratory failure of that, should go to the regular medical institutions, operated by professionals, in the professional operation can reduce the occurrence of side effects, to avoid leaving sequelae.
