2) Glucocorticoid drugs can effectively relieve acute exudation, reduce inflammatory reaction and interstitial edema at the lesion site, and effectively relieve diffusion dysfunction. Generally, methylprednisolone is 40-80mg per day, 10- 14 days. If the disease control is satisfactory, the dosage will be gradually reduced and the drug will be stopped after 2-3 months. If the condition is serious, the dose will be reduced more slowly. Some patients can completely stop using this hormone after 4-6 months.
3) Application of antibiotics: Antibiotics are generally not recommended for simple radiation pneumonia. However, due to the increased exudation of lung tissue and poor sputum discharge in airway, tumor patients have weak resistance after radiotherapy and chemotherapy and are easily infected. Antibiotics should be used preventively at this time, but not for a long time, so as not to induce fungal infection and complicate the condition. If there are no clear signs of infection, second-generation cephalosporins can generally be used. When glucocorticoid has controlled local inflammation and exudation, it can be stopped, usually for 5-7 days.
4) Application of antioxidants: Although there is no clear evidence, according to the results of animal experiments, the application of antioxidants can reduce the occurrence and degree of radiation-induced lung injury. The application of sulfhydryl expectorant drugs such as acetylcysteine or ambroxol can be considered, which is beneficial to scavenging oxygen free radicals, reducing the degree of radiation-induced lung injury and promoting recovery.
5) Severe patients can consider tracheotomy and positive pressure breathing.
