What reason is child temperature instable

summary

The development of neonatal body temperature center is not perfect, and the subcutaneous fat is thin, the heat preservation ability is poor, and the heat dissipation is fast, so the body temperature is often unstable. Especially at birth, when the newborn comes from the mother with constant temperature to the body with lower temperature, the body temperature often drops by about 2 ℃, and then gradually rises, Generally, it is stable between 36 ℃ and 37 ℃ within 12 ~ 24 hours. Let's talk about the reason why the child's temperature is unstable.

What reason is child temperature instable

First, in a day and a night, the body temperature fluctuates periodically. The body temperature was the lowest at 2-6 am and the highest at 1-6 PM. The amplitude of fluctuation is generally less than 1 ℃. This circadian periodic fluctuation of body temperature is called circadian rhythm or diurnal cycle. The change of body temperature is related to age. The body temperature of young people is higher than that of old people. With the increase of age, their body temperature has a tendency to gradually decrease, about every additional age (10 years), the average decrease of 0.05 ℃.

Second: the normal temperature of the baby's armpit is 36.3-37.3 degrees, the low fever is 37.4-38 degrees, the moderate fever is 38.1-39 degrees, the high fever is 39.1-39.9 degrees, and the ultra-high fever is that the temperature exceeds or reaches 40 degrees.

Third: place the thermometer horizontally between the folds of the neck skin, so that the skin can clamp the sensing end of the thermometer for at least 5 minutes, and it is best to clamp it for 10 minutes. The temperature measurement at this place is the most convenient, and there is no need to undress. The disadvantage is that the thermometer is not easy to fix, and the neck skin temperature is easily disturbed by room temperature, so the normal temperature at this place is 36.3 ℃

matters needing attention

First, dip the mercury sensor of the anal thermometer in a little food oil or glycerin, separate the buttock groove, and then insert it into the anus for 3-5 cm, 3 minutes. Although the temperature measurement is troublesome, it is the most correct, so it is better to use Anal temperature measurement when you are sick. The normal temperature is close to oral temperature measurement, and there is no need to reduce 0.5 ℃
