Pediatric bronchopneumonia is an inflammatory disease of the lungs caused by pathogens such as bacteria, viruses or Mycoplasma pneumoniae. When a child has pneumonia, the symptoms are also very obvious, including a variety of symptoms such as fever, cough, coughing, wheezing, and difficulty breathing, but not all of these symptoms may manifest themselves, and some pediatric pneumonia simply manifests as a simple cough. Pediatric pneumonia can progress from an upper respiratory tract infection to a lower respiratory tract infection, or directly to the lower respiratory tract. In addition to respiratory manifestations, children with severe disease may have combined respiratory failure and extra-pulmonary manifestations, such as vomiting, abdominal pain, diarrhea and even gastrointestinal failure in the gastrointestinal tract, increased heart rate and even myocarditis and heart failure in the circulatory system, and neurological manifestations such as toxic encephalopathy in various organs and systems. If a child has the above symptoms, it should be considered as a result of bronchopneumonia infection, which needs to be treated promptly. If it develops into severe pneumonia, it will involve the body’s circulatory system, digestive system and nervous system. And respiratory failure can occur, which can be life-threatening in severe cases.
