When your baby has a fever of 38.8 degrees, you need to observe your baby’s mental condition first. If the mental state is relatively good, able to eat, drink, sleep and play, it means it is not too serious. If the mental state is not good, it is a more serious situation. First of all, you need to give the child antipyretic drugs, because once the body temperature exceeds 38.5 degrees, for infants and children under three years old, it is easy to occur the phenomenon of high fever convulsions, which can produce irreversible damage to brain function, which is very serious. At this time, you can take oral ibuprofen suspension and acetaminophen pellets to reduce fever. You can also use physical cooling methods, such as wiping the child’s whole body skin with warm water, or putting fever patches on the forehead, neck and forehead, which is very useful for relieving fever, and also prolonging the action time of antipyretic drugs and reducing the use of antipyretic drugs. Because antipyretic medicine will have more or less side effects if used too much. In addition, the cause of the child’s fever needs to be identified and treated for the cause.
