Some people believe that “pediatric bronchopneumonia is dragged out”, mostly because they think that when a child develops some respiratory symptoms such as coughing without treatment, it will gradually develop into pediatric bronchopneumonia, but there is no clear clinical basis for this statement. Pediatric bronchopneumonia is an inflammatory reaction caused by direct invasion of the respiratory tract by pathogens such as bacteria, viruses or mycobacteria, and Mycoplasma pneumoniae, which in turn attack the bronchial walls or alveoli. The main symptoms include fever, cough, shortness of breath, and lung rales, and may also be accompanied by poor mental health, loss of appetite, and diarrhea, and are usually more likely to occur in winter and spring when the seasons change. In addition, it is also more likely to develop in pediatric populations that are themselves immunocompromised and malnourished. In the days before the onset of the disease, some children may develop symptoms such as coughing and progress slowly. This is closely related to the physiological characteristics of the pediatric population and is not the result of delayed treatment. For example, narrow tracheal and bronchial lumen, low mucus secretion, poor ciliary motility, and poorly developed pulmonary elastic tissue can lead to slow progression and recurrent episodes of pediatric bronchopneumonia, which requires identification of the primary disease and active removal of predisposing factors. Clinically, treatment of pediatric bronchopneumonia usually involves nebulization and oxygen therapy to help improve respiratory function, as well as sensitive antibiotics to control inflammation, such as cephalosporin, amoxicillin and methicillin for bacterial infections, and erythromycin and azithromycin for Mycoplasma pneumoniae infections. In addition, active prevention and treatment of complications are needed. For high fever, antipyretic drugs such as ibuprofen and acetaminophen can be given, and when there is sputum, tranylcypromine can be given to help expel sputum. During the treatment period, it is necessary to ensure a suitable environment, air circulation, isolation and prevention of cross-infection, and to ensure a comprehensive diet to meet the nutritional needs of the child. Generally, after systematic and standardized treatment, it can be cured.
