Fall and winter are the seasons when many babies have colds and fevers. So in the fall and winter season parents in the encounter of pediatric fever, how should be correctly treated? 1, establish the correct concept. Fever is the body’s defense response to disease, fever when the body’s immune function is enhanced, not only is conducive to the elimination of invasive viruses or bacteria, inhibit the growth and reproduction of viruses or bacteria, but also enhance the body’s ability to respond to stress. All of these are conducive to the removal of pathogens and promote the improvement of the disease. Therefore, to a certain extent, pediatric fever is not entirely bad, do not be too active to take antipyretic measures, on the contrary, may be conducive to the child’s recovery, so the general advocate of fever temperature does not exceed 38.5 ℃ do not need to use antipyretic drugs (except for those who have a history of febrile convulsions). Parents will ask: if you let it burn down, burn the brain how to do? In fact, brain damage caused by fever is often not caused by the fever itself. Because most pediatric infections are common endogenous infections, the fever it causes rarely exceeds 41 ℃, and this type of fever does not cause brain cell damage, leading to brain burn. As for the fever that may involve the brain, it is mostly seen in encephalitis, meningitis, sepsis, etc.; or ultra-high fever in heat stroke (body temperature is often close to 42 ℃), which leads to irreversible high-temperature denaturation of brain cell proteins. So whether or not pediatric fever affects the brain is largely determined by the nature of the disease that caused the fever. 2, because of fever when seeking medical treatment, should cooperate with the doctor to actively identify the causes of fever. Instead of being eager to get rid of the fever, the doctor should be asked to quickly reduce the fever, which will lead to the unreasonable use of certain drugs. Glucocorticosteroids (e.g., dexamethasone) are mainly used for the emergency treatment of autoimmune diseases, shock, and severe infections or inflammation. This kind of drug has no antibacterial, antiviral effect, but has immunosuppressive effect, improper use can promote the spread of bacterial or viral infections and aggravate the condition, may also make the tendency to improve the infection resurgence, in addition to aggravate the role of acetaminophen and other antipyretic drugs adverse reactions. Therefore, the hormone can not be used as pediatric fever anti-inflammatory cooling drugs. If this is the case, why some doctors still habitually use hormones to reduce fever? Emergency pediatrics doctors frankly, if you do not give high fever children quickly fever, many parents will be pestered. 3, do not heavy treatment, light care. Pediatric fever home care is also quite important, this time should rest, less activity, reduce clothing. Eat some juicy, easy to digest, nutritious food or fruit. Physical cooling is a safe, simple and reliable method to reduce fever, and can be used in all stages of fever. When the effect of drugs to reduce fever is not good or less than 2 hours after the use of drugs to reduce fever and body temperature more than 39 ℃ should also be used physical methods to reduce temperature. Such as warm water bath, the method is as follows: adjust the room temperature to about 25 ℃, will be placed in the child than the body temperature 2 ~ 3 ℃ of warm water immersion 10 ~ 15 minutes, with a large towel dry. 4.Fever caused by viral cold, as little as possible infusion, less antibiotics.
