It is unscientific and unreasonable that nine out of ten newborns have pneumonia on X-ray. The diagnosis of pneumonia should be based on clinical symptoms. If the clinical symptoms are highly suspicious of pneumonia, it can be combined with X-ray examination to comprehensively determine whether the newborn is suffering from pneumonia. The main symptoms of pneumonia are fever, cough, sputum and wheezing. The doctor’s diagnosis of pneumonia is usually a combination of biochemical tests and clinical manifestations. Nine out of ten radiographs show pneumonia. What is being considered may be a problem with the radiographs or a thickening of the lung texture caused by a cold, which does not meet the diagnostic criteria for pneumonia. In addition, it is also possible that newborns have poor resistance, and a cold can induce pneumonia. Clinical treatment is mainly anti-infection and expectoration, and should be based on the condition of the doctor’s advice. Nine out of ten newborns have pneumonia, and the diagnosis of pneumonia should be made through professional doctors’ auscultation and filming, which is not objective. When the doctor diagnosed the newborn with neonatal pneumonia, parents should actively treat it to avoid unnecessary effects.
