How to judge the normal value of children's anal temperature

Children's body temperature is affected by various factors such as season, environment, diet, etc. There are many ways to detect children's body temperature, such as armpit, mouth and anus. These three methods measure body temperature in different locations and have different normal body temperature ranges. Parents need to understand the range of different body temperatures for children in case their children have fever-like symptoms. They also need to understand how to determine the normal value of children's rectal temperature.

Dr. Zhang, a pediatrician, said: You can determine whether a child has a fever by measuring the temperature of the armpit, mouth and anus. Taking axillary temperature as an example, the normal body temperature of a human body is 36-37°C. The temperature difference between the anus, mouth and axillary is 0.5°C, with the axillary temperature being the lowest. That is to say, when the armpit temperature is 37℃, if the temperature in the anus is measured at the same time, it should be 38℃, and the temperature in the mouth should be 37.5℃. However, two points need to be noted: First, human body temperature fluctuates periodically within the normal range, with the lowest temperature in the early morning and the highest temperature in the afternoon and evening; the body temperature in summer is slightly higher than that in winter. Secondly, for children, especially infants, strenuous exercise, after meals (after feeding), crying, too thick clothes, and high room temperature can all cause the body temperature to rise to 37.5℃ (underarm) or even 38℃. Therefore, parents should pay attention to the above situations when measuring their children's temperature and make correct judgments.

When measuring the temperature of your child in different parts of his body, rectal temperature and oral temperature are more accurate than axillary temperature. If conditions permit, you can use two thermometers to measure the oral and anal temperatures at the same time. However, it is not recommended to use one thermometer to measure oral and anal temperatures separately, as this can easily lead to errors.

Measuring anal temperature is mainly used for children under 4 years old. It is recommended to turn on the digital electronic thermometer first, apply lubricants such as Vaseline on the end of the thermometer, fix the child's legs, and insert the end of the thermometer into the child's anus 1 to 2 cm. Hold the thermometer and wait for 1 minute or until the indicator light comes on to read the temperature.

Oral temperature measurement is mainly used for children over 4 years old. Open the thermometer and put one end of the thermometer under the child's tongue, insert it inward, let the child close his mouth and hold it for a while. After waiting for 1 minute or the indicator light comes on, you can remove the thermometer and read the number.

The above three are methods for measuring children’s body temperature, among which children’s rectal temperature is also a way to accurately measure human body temperature. It is necessary for parents to understand how to measure their children's temperature. Among the three methods of measuring temperature, they should be used at appropriate times. For example, if a child suffers from oral disease, it is not recommended to measure the temperature by mouth.
