Out of the misunderstanding: once the baby has a fever, many parents do not distinguish the reason, immediately use antipyretic drugs, which is a big taboo in medical treatment. Fever is not all bad, first of all, fever is a signal to report the baby’s illness, and secondly, fever is good for mobilizing the baby’s body immune function, which is conducive to killing and removing bacteria and viruses, and promoting the healing of diseases. Normal baby’s basic body temperature is 36.9℃-37.5℃. 1 year old infant’s body temperature below 37.5℃ is normal. The reason is that the baby’s thermoregulatory center has not yet developed, resulting in the baby’s body temperature will be affected by the environmental temperature. Generally, when the body temperature exceeds the basal body temperature by more than 1℃, it can be considered as fever. Hypothermia refers to a body temperature fluctuating around 38℃, and hyperthermia refers to a body temperature above 39℃. A fever of more than two weeks in a row is called a prolonged fever. How to deal with baby fever When the baby’s axillary temperature is lower than 38.5℃, take physical cooling, suggest to give the baby more water, reduce clothes appropriately, and then observe the body temperature, if it continues to rise, we should check the blood routine, so as to treat the symptoms with medicine. When the axillary temperature is above 38.5℃, you can use physical cooling plus oral antipyretics or see a doctor. The most common physical cooling is to use warm water bath, with about 37 ℃ warm wet towel to baby bath, wipe the whole body, including the baby’s forehead and face. When the weather is warm, you can choose to give your baby a warm bath directly, the focus is to control the water temperature, the water temperature is best to maintain at 38 ℃ – 40 ℃. How to use antipyretics Two antipyretics that are safe for children: acetaminophen effective for 3-4 hours and ibuprofen to maintain 6-8 hours, alternating between the two, see instructions for usage. The use of antipyretics is symptomatic treatment, which can only briefly lower the body temperature and make the body feel more comfortable. In principle, it is recommended to use them above the axillary temperature of 38.5°C, and the number of times should not be too many, the interval should not be too close, and avoid excessive use, which may cause hypothermia. The commonly used dosage forms for children are oral and suppository, of which oral is the most commonly used dosage form, which usually starts to take effect about half an hour after taking; suppository is directly absorbed through the rectal mucosa, which is suitable for those who cannot take it orally or need immediate cooling for high fever convulsions, and is not suitable for children with diarrhea. What are the conditions that require immediate medical attention when a baby has a fever? Babies who meet one of the following conditions should be sent to the hospital immediately. 1.Age within 3 months; 2.Fever of 40℃ or more for 24 hours with little or no urine; 3.Low temperature for more than 4 days; 4.Fever causing convulsions; 5.Vomiting violently or difficulty in swallowing; 6.Shortness of breath and purple lips; 7.Poor spirit, low activity, or even lethargy; 8.Rising again after 24 hours of fever remission.
