Today I would like to talk about a few points regarding pediatric fever. This is a very common topic, but many parents are confused by it, parents are most afraid of children’s fever, children’s fever always want to immediately down, a long time and afraid to burn the brain, with antipyretic drugs, a time after the fever rises again and very incomprehensible, and so on, many problems. In fact, fever is a defensive response of the body to external stimuli, most commonly infections, whose initial purpose is to kill the invader, so it is not good for the body itself to actively try to extinguish a fever that is not too high, but a fever that is too high does cause discomfort, especially in children, because the nervous system is not mature enough, excitement is easily generalized, and sometimes even causes short-lived cramps, i.e., febrile convulsions. Therefore, excessive fever should really be avoided and can be reduced by medication or physical means. But febrile convulsions are not the same as saying that high fever burns the brain, it is only a temporary phenomenon, as long as the brain itself is not a problem, most febrile convulsions are benign and can soon be controlled, only when the brain itself has problems such as encephalitis meningitis will cause persistent high fever and repeated convulsions, so that only the brain is bad will cause fever and convulsions, not fever causes brain burn, so to say is The cause and effect are reversed. The use of antipyretic drugs can only temporarily reduce fever, many parents do not understand, in fact, the reason is very simple, the role of antipyretic drugs is only to reduce fever, the treatment of the disease itself has no effect, so as long as the disease is not healed, fever will continue to exist, antipyretic drugs only temporarily reduce fever, so the fundamental or correct diagnosis and treatment of the disease itself, not just reduce fever. As the disease improves, the fever will gradually ease, but there is also a process, often manifested as a decline in the peak of the fever and a longer interval between fevers, so parents should keep good records of their children’s fever, so that they can promptly determine whether the child’s fever is in remission or intensified. In short, fever is a manifestation of disease, appropriate fever is not terrible, may be beneficial to the human body, too high fever needs to be properly controlled, and the use of antipyretic drugs should also be appropriate, one should be the correct dose, two must have a certain interval, three do not a variety of antipyretic drugs together, this is not good for children, compared to drugs, physical cooling is sometimes more appropriate. Nowadays, some drugs are mostly compound preparations, which cover up the antipyretic drugs, and parents will unknowingly use a variety of antipyretic drugs at the same time, which I am very opposed to, I hope that parents must read the ingredients of the drugs when using them, do not eat the wrong medicine. Of course, it should be stressed that fever is after all a sign of human disease, so the primary problem is to clarify the diagnosis and prescribe the right medicine, rather than just meet and pursue fever reduction and put the main enemy away.
