Bronchopneumonia is a common infectious disease in infants and children and is a common cause of hospitalization in children. Bronchopneumonia, also known as lobar pneumonia, is most common in children under two years of age and occurs in the fall and winter when the climate changes suddenly. The clinical manifestations are usually fever, cough and shortness of breath, and the child’s early temperature is often 38 to 39 degrees Celsius, but can also reach about 40 degrees Celsius. The cough and phlegm sound in the throat are usually obvious in the early stage. The cough is dry in the early stage, i.e., the cough can be reduced, and the cough increases with phlegm in the recovery period. Urgency mostly occurs in fever as well as in coughs and the like. Severe lung infections can cause dyspnea. The principle of treatment is to control inflammation, improve the ventilation function by infusion, give more sputum or phlegm-suppressing drugs …… with symptoms of wheezing, and give nebulization treatment when serious, such as budesonide and terbutaline to prevent and treat complications at the same time. In terms of care, we should ensure air circulation, maintain the room temperature at about 20 degrees Celsius and humidity at about 60%, give sufficient vitamins and proteins, drink water frequently and eat small amounts of food several times. Anti-infective drugs should be given with high sensitivity and in sufficient quantity. If necessary, glucocorticoids can be given for treatment.
