What is a fever all about? Almost everyone has had a fever, and when a child has a fever, parents get anxious. In fact, most fevers are caused by bacterial or viral infections, that is, they are feverish because they are sick. When we have a fever, our body’s temperature regulating point increases from the normal 37° to 38°, 39° or even 40°, which means that the body no longer takes 37° as the standard, but takes the new regulating point as the standard to regulate heat production and heat dissipation. Fever is the body’s protective response to infection, and at 38° to 38.5°, the body’s immune system is active, helping to control infection. Can fever burn my brain? A fever of 40° or less will not damage the brain unless the brain is inflamed by viruses or bacteria, such as meningitis or encephalitis, when the child is still depressed even after the fever has temporarily subsided with antipyretics, and may have convulsions, headaches, vomiting, etc. When is it necessary to reduce heat treatment? How to deal with it? Generally, children with febrile convulsions can take antipyretic medication at 38°. However, febrile convulsions usually occur one at a time, mostly within 24 hours of the onset of the disease, so antipyretic treatment may not necessarily prevent febrile convulsions from occurring. How to reduce fever? Children within three months of age generally take physical cooling methods, reducing clothing, warm water baths, water temperature and the child’s body temperature at the time, more water. Some parents, once their child has a fever, think that the baby is sick, we need to wear more clothes, covered tightly to come to the hospital, let them undress, but also reluctant. They do not know that this cover tightly, equivalent to insulation, will be high fever well insulation, how the body temperature down? When to keep warm? When the fever starts and the child is afraid of cold. Once the fever reaches its peak and the child is afraid of heat, you need to reduce the amount of clothing. You can take antipyretic medicine if you are three months or older. The safe antipyretics for children are acetaminophen and ibuprofen, which should not be taken at the same time and staggered if necessary. Acetaminophen should not be taken more than 4 times in 24 hours and each time should not be overdosed. After taking antipyretics, drink more water. Antipyretics are used to reduce fever by sweating. Remember to change clothes promptly after sweating. When do I need to see a doctor? A baby under 3 months of age with fever of 38.5° or higher needs to be seen in an emergency room. A baby with febrile convulsions, significant dehydration (low urine output, sunken fontanelle) and breathing difficulties needs to be seen in an emergency room. Outpatient visits are usually sufficient. When do I need to see a doctor again? First: if the temperature temporarily drops after taking antipyretic medication (not necessarily to normal), then the spirit is not good; second: the fever does not go away after three days at home; third: new symptoms appear; fourth: the existing symptoms are significantly worse. Must I take anti-inflammatory drugs for fever? Fever does have inflammation, but this inflammation can be caused by viruses and bacteria, etc. Most colds are caused by viruses, and the anti-inflammatory drugs in the mouth of the people are actually antibiotics, which are only effective against bacteria, mycoplasma, chlamydia, etc., and are not effective against viruses. Only the fever caused by bacteria need to take anti-inflammatory drugs. Anti-inflammatory drugs are chemicals, the human body is not a chemical factory, need is what it should be, abuse of antibiotics will lead to bacterial resistance, the real bacterial infection when the antibiotics are not effective. Do you need to hang water for fever? The people of the world are deeply impressed by the idea of hanging water. The most extreme encounter with a grandmother to take her granddaughter to the doctor, the little girl 7 days no stool, uncomfortable, the grandmother said: “doctor, hang some water, often encounter parents said, “doctor, our baby high fever, hang some water. Most of the parents who have this request are working, rural, low education level, not to hang him, said the doctor’s attitude is bad, no medical ethics. It makes the doctor laugh and cry, communication, it is useless, can not understand. Saline is not fairy water, cold hanging water is useless. Hanging water hanging is antibiotics and water, salt (salt here is not the salt eaten, refers to sodium chloride potassium chloride, etc.). Among all the methods of medication, it is the most allergic, and even if the quality of the hanging solution is good, there are always tiny substances that cannot be discharged by the body and accumulate in the body, blocking the end of the capillaries. It is only when the bacterial infection is heavy and when you eat significantly less that you need to hang water, and generally children over two or three years old take medication that works well; there is also dehydration that is obvious and cannot be replenished orally with fluids.
