Newborn fever is a common and normal body’s defense response to various harmful stimuli, which has an important stimulating effect on the immune system. Generally speaking, fever is an abnormal increase in body temperature, and the normal body temperature of a newborn can fluctuate within a certain range. If the mother finds that the baby has a short-term body temperature fluctuation, but the whole body is in good condition, it is not considered that the baby is sick.
Under normal circumstances, the axillary body temperature of newborns is generally 36-37℃; the average of the three seasons of spring, autumn and winter is 36.6℃ in the morning, 36.7℃ in the afternoon, 36.9℃-36.95℃ in the morning, and 37℃ in the afternoon in summer. When breastfeeding, after meals, exercise, crying, clothing is too thick, and the room temperature is too high, the newborn’s body temperature can temporarily rise to about 37.5℃, even occasionally as high as 38℃; on the contrary, if the baby is hungry and has low body heat, There are also some frail children who are in a state of low activity or poor warmth, their body temperature can drop to about 35 ℃, clinically it is said that the body temperature is hypothermic or the body temperature does not rise, and warm measures should be taken in time.
The best way to tell if your baby has a fever is to measure its temperature. The method of measuring body temperature also affects the real body temperature value. If the time and conditions of the body temperature test are different, the measured body temperature value will be different. For example, the values measured on the axillary surface, oral surface and rectal surface differ by about 0.5℃, namely The axillary surface was the lowest and the anal surface was the highest. The axillary temperature should be measured in 5 minutes, not more than 10 minutes, the body temperature will gradually increase over time. If there is local inflammation in the mouth and anus, the measured value is higher, but the value measured by the armpit meter in a cold environment may be lower. Therefore, for the suspected fever of the baby, the mother should carefully check the body according to the environmental changes. Accuracy.
Fever can be divided into four categories: low fever: less than 38°C. Moderate heat: 38°C-39°C. High fever: 39℃-41℃. Extreme heat: greater than 41°C. Because newborns have better tolerance to fever and show little response, sometimes the body temperature can suddenly rise as high as 40 ℃ when catching a cold. The body temperature of older babies tends to stabilize. If the baby’s body temperature rises suddenly, the body is in the poor physical condition and there is no energy, it often reflects the occurrence of more serious diseases. If the baby has a fever for more than 2 weeks or the body temperature rises repeatedly, the mother should take the baby to the hospital in time to find out the cause carefully, so as to avoid adverse consequences.
