Children with high fever should go to the pediatrician in time to clarify the cause of their high fever, improve relevant tests such as chest X-ray, sputum culture, stool routine, etc., and then give symptomatic treatment. Specific treatment methods are as follows: 1. Physical cooling: If the child is in a good state of mind, you can drink more water or carry out physical cooling, such as alcohol rubbing, warm baths, etc. Do not blindly use antipyretic drugs at this time. Because antipyretic drugs only play a cooling role, and not for the pathogens that cause disease treatment, blindly using antipyretic drugs may cause side effects; 2, reasonable clothing: children with high fever should not wear too many clothes, do not cover too thick, not to cover the sweat, so as not to affect the heat dissipation, so that the body temperature rises even higher, but also pay attention to keep warm. If you have cold hands and feet and chills at the same time as high fever, you need to add clothes in time; 3. Medication: When the body temperature is higher than 38.5℃, it is recommended to take the antipyretic medicine ibuprofen suspension or acetaminophen orally as prescribed by the doctor, while using it, you must pay attention to the dosage. In addition to the above heat treatment, parents must closely observe the child’s condition during high fever, if you find that the child is depressed, pale or have vomiting, diarrhea and other conditions, then you should immediately go to the hospital to prevent the deterioration of the condition.
