Children with positive Mycoplasma pneumoniae are mainly treated with infections, and for severe cases, glucocorticoids and bronchoscopy may be added, depending on the condition. 1. Anti-Mycoplasma pneumoniae treatment: macrolides are preferred, and azithromycin is commonly used in children. For some drug-resistant mycoplasma, specific problems need to be analyzed. Specific drugs should be used under the guidance of a doctor after weighing the pros and cons. 2. Glucocorticosteroids: Glucocorticosteroids are not routinely used for ordinary children, but can be considered for children with acute onset, rapid development and severe disease. 3. Gammaglobulin: When combined with central nervous system symptoms, immune hemolytic anemia and other autoimmune diseases, the use of gammaglobulin can be considered under the guidance of the doctor. 4. Pediatric flexible bronchoscopy: bronchoscopic lavage is important for timely relief of respiratory obstruction and reduction of intrapulmonary inflammatory response. For the same disease, different patients with different physical conditions, different stages of the disease and different treatments should be treated in a timely and standardized manner under the guidance of a doctor.
