Pneumonia in pediatric patients is a relatively common respiratory disease, an inflammation of the lungs caused by different pathogens or other factors, with fever, cough, shortness of breath, dyspnea and fixed medium and fine wet rales in the lungs as its common clinical manifestations. Severe pneumonia can accumulate circulatory, neurological and digestive systems, and the corresponding clinical symptoms, such as heart failure, toxic encephalopathy and toxic paralysis, appear. The specific symptoms of pediatric pneumonia are as follows: 1. Cough: often more intense, mostly dry at the beginning, with sputum gradually increasing in the middle and later stages. However, in newborns with pneumonia, the cough may not be obvious and may only manifest as spitting, choking, or spitting up milk. Fever: Most children with pneumonia will have a fever, which can be high or low, but neonatal pneumonia often has no fever. Some school-age children with severe pneumonia, such as mycoplasma pneumonia, have a predominantly high fever. 3. Shortness of breath: The more extensive the lesions in the lungs, the more pronounced the shortness of breath, and you can even see the child’s nose flapping with breathing. 4. Wheezing: Infants and children with pneumonia are prone to wheezing, which is characterized by a “hissing” voice, like a bellows. 5, chest pain: uncommon. When the inflammation in the lung is close to the chest wall, causing pleural reaction or even pleural effusion, chest pain will occur. 6, abdominal pain: individual severe pneumonia combined with pleural effusion can appear ipsilateral abdominal pain because it affects the pleural pulling action. When the child is depressed, has difficulty breathing, is pale or blue, and has blue lips and nail bed, he or she needs to go to the emergency department of the nearest hospital as soon as possible. If the cough is heavy or accompanied by wheezing and oral medication is ineffective; fever for more than 3 days with no decreasing trend of peak; sputum is abundant or yellowish in color, poor spirit and appetite, abdominal pain, etc., one of the above symptoms needs to be seen at the hospital.
