What to do about a child's high fever?

Doctor's answer:

Hello: Childhood fever is the body's response to fighting the disease. Fever helps eliminate bacteria and control inflammation. Of course, it doesn't mean fever is absolutely beneficial for the body. If the fever lasts too long or the temperature is too high (above 39°C), the consumption of nutrients and oxygen in the body will increase, affecting normal metabolism and causing a series of discomfort symptoms, such as poor appetite, bloating, diarrhea, and constipation. High fever can also affect brain function, leading to convulsions.
Therefore, for high fever in children, the first priority should be to use physical cooling methods. For example, soak a towel in cool water and place it on the forehead, changing it every 5-10 minutes; or place a cold water-filled hot water bag behind the head. Another method is to soak a large towel in warm water, wring it out, and place it on the chest and back (stop applying if the child's face turns blue or shivers). Alcohol or (white wine) mixed with half warm water can be used to wipe the neck, armpits, groin, palms, soles, chest, and back for several minutes to lower the temperature. If the fever still doesn't subside, medication can be used for cooling, such as intramuscular administration of Antipyrine.
After 1 hour of physical cooling, measure the temperature to observe if there is a sudden drop in body temperature or weakness. If so, provide warmth and drink hot water. Additionally, monitor for any new symptoms, such as changes in consciousness, rashes, vomiting, or diarrhea.
After medication-induced cooling, observe if there is excessive sweating. If so, drink more plain water with added salt and sugar to replenish lost fluids and electrolytes. Replace wet clothes soaked in sweat promptly to maintain skin cleanliness. Children with high fever should also rest in bed, with moderate room temperature and good ventilation.
