Fever is a common symptom of most diseases in pediatrics. Fever can lead to discomfort such as depression, increased heart rate and loss of appetite; in severe cases, it can even lead to high fever convulsions. A child with a high fever that does not go away also usually makes mothers anxious and travel to and from the hospital every day. Oral antipyretics are needed when the temperature reaches 38.5°C or higher. What if the baby’s fever does not go down even after taking Merlin? To treat children’s fever correctly, it is important to be able to clarify the cause of the fever, and at the same time treat the disease, you need to master the timing of oral antipyretics and physical cooling methods. While taking oral Merlin on time to reduce fever, it is important to give the child more water so that he can pee more. Drinking water will have some unobtrusive evaporation and take away a lot of heat from the skin. Peeing can also take away some of the child’s body heat. If it is a particularly small baby to pay attention to open the wrap, do not wrap too tightly, can help heat dissipation, of course, according to the temperature conditions in the room to choose how much to wrap, can not catch cold again. We found that some babies around one year old, usually held by parents, and hold will also be very tight, the baby’s body surface area is small, half the volume of the body will be attached to the parent’s body, which will affect the baby’s heat dissipation, so that he continues to maintain high fever, should let the baby stay by himself, or loosely sitting on the parent’s lap. Don’t overdress your child, because children move well and it is appropriate to wear slightly less than adults overall. For fevers without a clear cause, it is imperative to actively treat the fever while carefully observing the changes in the child’s systemic symptoms and providing the doctor with a clear and reliable medical history to find the cause and treat it as soon as possible.
