Bronchoscopic examination of the bronchial opening reveals erythema of the mucosa, accompanied by a large amount of concentrated secretion, suggesting that bronchial inflammation may be present and requires prompt treatment. When the bronchial tube is infected with pathogenic bacteria, the pathogenic bacteria will irritate the bronchial mucosa and cause redness and swelling of the mucosa, and at the same time, the inflammation will stimulate the glands on the mucosa to secrete a large amount of secretion, forming a concentrated secretion. This can be detected by bronchoscopy. When bronchial inflammation occurs, antibiotics such as amoxicillin and azithromycin need to be taken in time to control inflammation and relieve symptoms when it is clear that it is a bacterial infection. Drugs are recommended to be used in strict compliance with medical advice, the emergence of adverse reactions should be timely medical treatment, drug allergy is prohibited.
