A parent left a message asking Doudehui: What should I do if my baby has a fever?

what to do when baby is having a fever? In fact, babies\’ fever is a mechanism of the body\’s self-protection. The normal baby\’s rectal temperature fluctuates between 36.9℃~37.5℃. The sublingual body temperature is 0.3℃~0.5℃ lower than the rectal temperature. The armpit temperature is 36℃~37℃. This difference changes with time. The increase in body temperature becomes less obvious when wearing clothes, and the three are basically the same during high fever. From birth to 4 to 5 months, the baby has immunity acquired from the mother. The mother delivers some immune globulin to the baby through the placenta, and breast milk (especially colostrum) contains a large amount of immune substances. Even if pathogens or chemicals invade the baby\’s body, there will be no disease or even fever. However, after 6 months of birth, the immunity obtained from the mother gradually decreases, and the baby\’s own immune system has not yet developed into a fever, so it is easy to have frequent fevers during this period. Generally, the normal body temperature of babies varies slightly from individual to individual, but when the body temperature exceeds the basal body temperature by 1°C, it is a fever. Generally, fever is more likely to cause body temperature to rise at night, and fever from a common cold will end in about 3 days. If the baby has no other symptoms except for a general fever, is not crying and is moving normally, and has a normal appetite, it can be observed at home. However, if the fever persists and then returns again after subsided; in addition to fever, if there are symptoms such as cough, vomiting, diarrhea, general weakness, and ugly face, you should go to the hospital in time. Home treatment methods for babies with fever: ▼ Antipyretic has no side effects due to physical cooling, and is more convenient to use, so it can be used at home. You can use ice pillows, cold compresses on the head and other methods to reduce fever. You can use cold compresses on the armpits or groin, but be careful not to use too much ice. You can also take a warm water bath for 15 to 20 minutes with a water temperature of 37°C to 38°C (it feels neither cold nor hot when you put your hands in the water), or extend the time according to your body temperature, and dry your whole body afterward. However, some people think that cold compresses and warm water Bathing violates physiological mechanisms and is not recommended. ▼When you have a fever, keep warm properly. In the early stages of fever, your baby will feel chills and shivers, so you can keep warm properly. But be careful not to keep warm too much, especially for babies, to prevent \”heat-covering syndrome\” caused by excessive keeping warm. ▼When reducing fever, let the heat escape. When the body temperature rises, it is necessary to cool down in time to prevent febrile convulsions. You should wear fewer clothes or quilts to allow the heat to escape. Sweating will occur when fever subsides. Wipe sweat in time, change sweaty clothes in time, and do not let your baby face the air vent or fan to avoid catching cold. ▼When replenishing water and heating, the water in the body is easily lost, so you must replenish more water. You can let your baby drink warm water, warm milk, rice soup, etc. You can also give your baby fresh fruit juice, etc., and feed it in small amounts multiple times. ▼Baby\’s diet during fever If the baby can drink breast milk or milk, there is no need to worry too much. The baby should eat light, vitamin-rich, and easily digestible food to reduce the burden on the gastrointestinal tract. Encourage your baby to eat more fruits and vegetables, and eat small meals frequently. It is best to give them soup noodles, soup noodles, porridge and other foods with high water content. Do not force them to eat food they do not want to eat, and do not let them eat too much to avoid vomiting or abdominal discomfort. ▼When you have high fever, you can use antipyretics. When your baby continues to have high fever, he will fall asleep.If you can\’t eat or drink, you won\’t be in good health if you don\’t use antipyretic drugs. If the body temperature is above 38.5℃ and the baby feels uncomfortable, you can use antipyretic drugs. After using the antipyretic medicine, if the body temperature drops by about 0.5°C half an hour later, it means it is effective. However, it is important to understand that antipyretic drugs are not medicines to cure the disease, nor can they lower the body temperature to normal. When infected with influenza virus and varicella-zoster virus, if you use aspirin-type antipyretics, it may cause \”Reye\’s syndrome\”, which will cause severe symptoms and be life-threatening. When the disease occurs at night and you cannot go to the hospital immediately and you must use general antipyretic drugs on the market, you must first confirm the ingredients of the antipyretic drug. Do not use aspirin by yourself, but must use acetaminophen (also called paracetamol) or ibuprofen series antipyretics. Once high fever occurs, family members should not panic, but should observe carefully and tell the doctor the detailed condition of the baby so that the doctor can make a quick and correct judgment. In addition, body temperature changes during fever are also a very important judgment tool. Generally, body temperature is measured every 4 to 6 hours. If parents are worried or the baby\’s body temperature changes, they can measure it immediately. The record can be given to the doctor for reference during the visit. ▼Keep an appropriate indoor temperature at 20℃~25℃, and maintain air circulation to let in fresh outdoor air. Tips on what to do if your baby has a fever: 1. Will continued fever burn out the lungs? Fever when the human body is sick is a reaction of the body to the disease. It can promote blood circulation, enhance the activity of white blood cells, improve the body\’s resistance, and is conducive to the recovery of the disease. Of course, continued high fever is detrimental to human health. It will increase the burden on the heart and blood vessels, cause cerebral cortex dysfunction, affect gastrointestinal function, cause malnutrition, and then reduce the body\’s resistance. Some babies start out with a cold and fever, but parents don\’t care. They go to the hospital only when the fever persists and the condition worsens. After examination, it is likely that they have pneumonia. So is pneumonia \”burned out\” by high fever? In fact, fever does not directly damage the lungs. These babies start with upper respiratory tract infections in the nose and throat. Without timely and effective treatment, the invading bacteria or viruses invade the lower respiratory tract – the lungs, causing pneumonia. Fever is a sign of uncontrolled infection, and pneumonia is the result of infection. Therefore, when a baby has a cold and a fever that persists, parents cannot just be satisfied with taking a few antipyretics to \”suppress\” the body temperature. They should also use other drugs to remove the cause of the disease in a timely manner, so as to prevent further invasion of germs. Really prevent the occurrence of pneumonia. 2. Is fever necessarily harmful? Fever is a normal response of the human body to resist disease and is beneficial to the baby\’s recovery from the disease. Only excessive fever will have an adverse effect on the baby. In babies with respiratory infections, fever is often caused by viral or bacterial infection. When viruses or bacteria invade, the body releases some chemicals called \”cytokines\”, such as interleukin-1, interleukin-1, through monocytes and lymphocytes in the blood and macrophages in the tissues. 6. Tumor necrosis factor and interferon, etc., which have the effect of \”endogenous pyrogens\” and stimulate the anterior hypothalamus.Prostaglandins are produced in the region, which increases the body temperature control point, breaks the normal balance of heat production and heat dissipation, increases heat production, and reaches a balance of heat production and heat dissipation at the high body temperature control point, leading to fever. Studies have shown that the body\’s immune function is stronger during fever than at normal body temperature. Fever also has some immune-promoting effects and can inhibit the growth of certain microorganisms.
