Pediatric pneumonia is a common pediatric respiratory disease that leads to a high mortality rate in children and is currently the leading cause of death in children worldwide, with worldwide epidemiological surveys showing that pneumonia remains the leading cause of death in children under the age of five. Depending on the condition of the child, pneumonia can be divided into mild pneumonia and severe pneumonia. Mild pneumonia generally presents with fever, which can reach 39°C or even 40°C, mostly recurrent fever, with the temperature rising again after the fever subsides, coughing, coughing, wheezing, chest pain, and difficulty breathing. Changes, rapid heartbeat, blue lips, even respiratory failure and heart failure, may also involve the central nervous system, digestive system, etc., serious can be life-threatening. The pneumonia is relatively serious, because children’s resistance is relatively poor, once infected with pneumonia, the disease progresses very quickly and can easily develop into severe pneumonia, or even respiratory failure, heart failure, toxic encephalopathy, etc., leading to an aggravation of the disease and endangering the life of the child. Therefore, once a child is diagnosed with pneumonia, it is recommended that he or she be immediately hospitalized for standardized treatment to identify the cause of the pneumonia and select targeted anti-infective treatment, as well as symptomatic supportive treatment.
