Pediatric fever is one of the common symptoms in pediatrics, and many parents who come to the clinic are very worried about their children’s fever, worrying that it may “turn into encephalitis, pneumonia, etc.”. In fact, fever is caused by pathogenic bacteria (bacteria, viruses, mycoplasma, etc.), when these pathogens invade the body, the body’s defense system to protect the body, the body can make a variety of protective response to defend against pathogens, fever is one of the defense response. In other words, fever is only a manifestation of the disease, a fever caused by the disease, but not a fever burned into the disease. Fever is not a bad phenomenon, indicating that the body is fighting pathogenic bacteria. Generally speaking, it is not necessary to use antipyretic treatment below 38.5℃, and antipyretic measures should be used above 38.5℃. If the fever does not subside, especially if the high fever persists, it is very damaging to the human body, but if the fever is mild, or if the condition is very mild but temporarily inconvenient to seek medical attention, physical cooling methods can be used to relieve it. If the fever is more serious, or very uncomfortable is necessary to go to the hospital. And take some measures just to relieve the discomfort. When the disease is mild, you should also take the temperature more often and pay attention to whether the temperature has dropped, and if it does not drop for a long time, you must seek medical attention. First, let’s understand the fever gradation: according to the temperature can be divided into low fever: 37.4 ~ 38 ℃; moderate fever: 38.1 ~ 39 ℃; high fever: 39.1 ~ 41 ℃; ultra-high fever: 41 ℃ or more. Secondly, we are familiar with the commonly used physical cooling methods: 1, drink warm water: in response to fever, the most effective physical cooling method is to drink water. And drinking water is not suitable for drinking cold water. There is a certain temperature of warm water is most appropriate. The first drink of water to replenish body fluids, water has a certain effect on cooling when the body’s specific heat is high enough water. The second is to promote sweating, sweating can help the body exhaust heat. Of course, if the fever is caused by the cold, a cup of cold punch will also be some help. 2, warm water wipe: body slight fever, if someone to take care of, it is best to boil water. Pour out some water at a time to mix into warm water. Then soak a hand towel in warm water and wring it out, wipe the body forehead, neck, armpits, thigh roots and other parts of the wipe 5 to 10 minutes. Because the evaporation of water has a heat absorption process, so there is a cooling effect. In addition, if convenient, you can directly take a warm bath to help cool down. In fact, it is the use of water evaporation cooling method. The main reason why cold water is not used is because of fear of head irritation caused by discomfort. Similarly, alcohol is used to wipe the forehead, using evaporative heat dissipation. If the head is more refreshing, people will be more spiritual. 3, appropriate heat dissipation: more ventilation, pay attention to heat dissipation, dress generously, avoid wrapped in cotton. In summer, you can use air conditioning, room temperature control at about 27 ℃, pay attention to regularly open the window ventilation, so that the room air convection. When a fever is caused by a cold, you cannot just pursue heat dissipation and must have certain measures to prevent catching a cold. If it is a fever, do not keep the body too warm to prevent the body temperature from dissipating. Especially for small infants, too much warmth can easily cause fever and hyperthermia, so shaking open the wrap and other heat dissipation can reduce fever very well. However, if the winter like the first attention not to cause a cold. 4, cold compress head, in fact, head cooling on the body cooling effect is not great, mainly to make people feel more awake a little to relieve discomfort, so the front said more water is the key. Putting cold water in a cold compress to wear a cold compress on the head is also a common measure, if the water is too cold some people are also uncomfortable, you can put a towel on the forehead in put an ice pack. Cold compress recommended dry compress, too cold in fact is not good. Can also use commercially available “fever post” paste in the baby’s forehead to help cool the heat. Once again is the drug cooling: the above measures are not obvious, you can take oral antipyretic drugs, commonly used antipyretic drugs are oral ibuprofen, acetaminophen, etc.; for oral drugs difficult baby, you can also use antipyretic suppositories to help reduce fever. 6 months of age or younger babies try to use physical cooling. Those with a history of febrile convulsions should be sedated at the same time (under the guidance of a doctor) on the basis of effective cooling. In addition, while giving your baby a fever reduction, let your baby sleep more, to ensure sufficient sleep can be beneficial to the recovery of the disease. Pay attention to your baby’s mental state. If he or she is in poor mental condition and has obvious physical discomfort, you should go to the hospital as soon as possible to find the cause of the illness so as not to delay it. Finally, we wish our babies good health! We wish you all the best!
