Acute bronchitis is an inflammation of the bronchial mucosa caused by various pathogens and is a common respiratory disease in childhood, with more frequent and heavy incidence in infancy and early childhood. It is mainly an infection, caused by viruses, Mycoplasma pneumoniae or bacteria, or a combination thereof. In terms of treatment, the first thing is general care, paying attention to rest, maintaining a good surrounding environment, and keeping the child hydrated. Observe the change in body temperature. If the body temperature is below 38.5 degrees Celsius, antipyretic drugs are generally not needed, and antipyretic treatment is given when the body temperature is above 38.5 degrees Celsius. The next step is to control the infection. Since the pathogens are mostly viruses, antibiotics are generally not used. If bacterial infection is suspected, appropriate antibacterial drugs are selected according to the possible infecting bacteria. The main symptom of pediatric acute bronchitis is coughing. Cough suppressants can be given as appropriate, but overdosing should be avoided to inhibit the coughing up of secretions. When a child coughs and coughs up sputum, it indicates an increase in bronchial secretions. To promote the smooth discharge of secretions, nebulizing inhalers can be used to help expectorate sputum. Most children with acute bronchitis have a mild condition and should be treated with medication and care at home.
