If the baby's temperature is below 38.5℃, it is not necessary to take antipyretics, and other measures can be taken to cool down. First of all, the indoor environment should be kept quiet, with moderate temperature (18℃ ~ 25℃) and good ventilation, and the clothes should not be too thick. If you sweat too much, you should change clean clothes for your baby in time and scrub with warm water. When the baby has a fever, his breathing will be accelerated, and a lot of water will evaporate. Therefore, it is necessary to replenish water in time, so that the baby can drink more warm water, so as to make him urinate more and sweat more, and the temperature drop is 38.1℃ ~ 39℃ is moderate fever, 39.1℃ ~ 40.4℃ is high fever, 40.5℃. Specific methods: Wet the towel with warm water, and after wringing it slightly dry, rub the baby's neck, arms, chest, back, thighs and other parts, and rub the large blood vessels located in elbow fossa, armpit and neck a few times, with reddish as appropriate. You can also put an ice pack or a cold towel on the child's forehead to reduce the oxygen consumption of the brain and play a role in lowering the body temperature and protecting the brain. Don't use alcohol bath to cool down, because the baby's skin is delicate and the alcohol capacity is easily absorbed into the body, which will cause the baby to be agitated and cry. If the baby's temperature is above 38.5℃, you can take antipyretics. The use of antipyretic drugs for babies should be taken strictly according to their weight. The commonly used antipyretic drugs for babies include acetaminophen (such as Tylenol and Baifuning) and ibuprofen (such as Merrill Lynch and Thorne), which are all antipyretic and analgesic drugs. Acetaminophen takes effect quickly, has strong effect and high safety, so it can be the first choice. Ibuprofen reduces fever quickly and steadily, lasting for 6-8 hours, and is generally used for children over 6 months. Antipyretic drugs achieve the purpose of reducing fever by sweating. Therefore, after taking antipyretic drugs, you should give your baby plenty of warm water to sweat, or use warm water to wipe the bath to help reduce fever. Many mothers will encounter this situation. Less than 4 hours after taking antipyretics, the baby's body temperature has risen above 38.5℃. At this time, the baby can no longer take antipyretics, but can only watch the baby burn. In fact, there is a way to deal with this situation, that is, to prepare acetaminophen (such as Tylenol) and ibuprofen (such as Merrill Lynch) at the same time, and use the two drugs alternately, which can reduce the number of times each drug is used within 24 hours and reduce the side effects of the drugs. The specific administration method is: ibuprofen can be given to the baby 4 hours after acetaminophen is used. 6 hours after taking ibuprofen, if the body temperature rises again, you can take acetaminophen again. If the baby's body temperature rises again less than 4 hours after taking the medicine, he can't continue to take the antipyretic medicine once, but change to another antipyretic medicine. If the baby has febrile convulsions, the two drugs can be used at the same time, and the dose remains the same. Many parents have the feeling that babies are prone to high fever at night. This is because the proportion of water in the baby's body is higher than that of adults. As long as it is slightly short of water, it will affect heat dissipation and lead to an increase in body temperature. When the baby is sick, his spirit is poor, he sleeps for a long time, and he doesn't eat or drink water for a long time at night, so his body temperature is more likely to rise. If the baby falls asleep at night and has a high body temperature, wake him up to take antipyretic drugs or do physical cooling, otherwise the high body temperature will lead to febrile convulsions. If the baby's temperature continues to exceed 39℃, and he is listless or has a history of febrile convulsions, he can take antipyretics at home first and then send him to the hospital in time. Most colds are caused by viruses. Viral colds generally show a continuous increase in body temperature, and antipyretic drugs have certain effects. Moreover, viral colds are self-limiting, and when they reach a certain course of disease, their body temperature will naturally drop. Therefore, during the fever caused by viral cold, let the baby drink more water and have more rest. When the body temperature exceeds 38.5℃, use antipyretics ● Babies under 4 months should not use antipyretics, just feed more water and reduce the heat dissipation of clothes appropriately. If the body temperature cannot drop, take the baby to the hospital to see a doctor. At present, intramuscular injection of antipyretics is not recommended, because it may cause local infection or gluteal muscular atrophy and sciatic nerve injury. In particular, antongding or compound aminopyrine can also produce acute agranulocytosis after injection. Fever, the first "protective wall" in the body, is a symptom and a normal immune response in the body, which helps to sterilize and enhance resistance. When you have a fever, all kinds of immune functions in the body are "activated", metabolism is accelerated, antibody synthesis is increased and phagocytic activity is enhanced. These immune reactions can inhibit the growth and reproduction of pathogens, which is conducive to the recovery of the disease. Therefore, fever is a "protective wall" in the body and a kind of self-protection of the human body. If we are eager to use drugs to forcibly cool down before the cause is diagnosed, it is equivalent to supporting the pathogenic effect of pathogens, which will make the child more ill and have a longer course of disease. When the baby has a fever, mothers can take it easy as long as they know the correct nursing, because sometimes, fever is not all a bad thing.
