When the baby’s fever does not subside even after taking antipyretics, the child should be quickly given physical cooling, such as diluted white wine, alcohol or a warm towel to wipe the child’s skin all over the body, especially the armpits, groin, neck, which are rich in large blood vessels, the wiping time can be slightly longer to help reduce the baby’s fever. Secondly, the cause of the baby’s fever should be treated in order to reduce the fever, for example, fever in many cases is caused by inflammation, there will usually be elevated white blood cells in the blood routine, or elevated C-reactive protein. If the fever is indeed caused by inflammation, the use of anti-inflammatory drugs is often effective in reducing the fever. In addition, if a baby’s fever does not go away, rheumatic immune system diseases or blood system diseases cannot be ruled out. The child should be examined for blood system and rheumatic immune system related tests to rule out diseases such as leukemia, bone marrow suppression or lupus erythematosus of the rheumatic immune system.
