When lung abscess is diagnosed, it is necessary to actively cooperate with the doctor’s treatment, and common treatment methods include medication, drainage of pus, and surgical treatment. 1. Drug treatment: if it is caused by bacterial infection, antibiotic treatment should be applied, such as cephalosporin, penicillin, etc.; if it is caused by anaerobic infection, metronidazole can be used to treat it, which should be used under the guidance of a physician. 2. Pus drainage: for patients with lung abscess whose sputum is thick and not easy to cough out, saline and expectorant drugs can be used for nebulized inhalation, and then sputum can be drained through postural drainage. 3. Surgery: For lung abscess with a duration of more than 3 months, ineffective medical treatment, or abscess cavity larger than 5cm or more, or hemoptysis ineffective medical treatment or life-threatening, or accompanied by bronchopleural fistula, timely surgical treatment is needed. If the symptoms of lung abscess are not relieved or aggravated, you should go to the hospital in time to avoid delay.
