Mothers are always particularly attentive to their babies’ body temperature. In the course of daily child care, some mothers often become anxious about their children’s questions: “Why is the baby a little warm?” “Is the baby sick?” “Is the baby wearing too much?” In fact, there is no need to guess, the easiest way to determine whether the temperature is normal is to take a measurement, but what is the correct and safe way to measure the temperature? How much is considered a fever? I heard that the value should be increased by 0.5 ℃ on the measurement of what is going on? Here I’ll talk about the common sense that you should know about taking your child’s temperature. Normal body temperature Body temperature refers to the core temperature of the body, the measurement site can be measured by different parts, should be different thermometers to measure. The closest to the core temperature should be the anal temperature, the normal value of 37.5 ± 0.3 ℃. If the baby’s anal temperature is ≥38°C, it is defined as fever. According to foreign studies, the anal temperature, oral and axillary temperatures are reduced by 0.5°C in turn, and the tympanic temperature is basically the same as the anal temperature, which is why some times the measured temperature should be increased by 0.5°C. Measuring parts Body temperature measuring parts: oral cavity, rectum, axilla, forehead and ear canal, buttocks, back scapular area, where the most common measuring parts are oral cavity, rectum, axilla, forehead and ear canal. Measurement tools Glass mercury thermometer is the most traditional tool for measuring body temperature, but it is not recommended for infants and children because it is prone to breakage and mercury leakage. Electronic thermometers are accurate and fast, and have gradually replaced the traditional glass mercury thermometer for measuring body temperature in children abroad. Infrared thermometer can measure the body temperature through the forehead and tympanic membrane, the measurement is fast but the error is large, only used for safety inspection or screening of a large number of people. Forehead patches are used to determine temperature changes through color changes caused by chemical reactions, which are easy to manipulate, not very accurate and not reliable. The correct measurement method Children under 5 months of age can use axillary electronic thermometer to measure temperature. children over 5 months of age can use electronic thermometer to measure oral and rectal temperature. Judgment of measurement results The cause of fever and severity of disease cannot be inferred from the highest body temperature, and the duration of fever is not related to the severity of disease. Excessive warming and disease fever Babies are susceptible to the influence of environmental temperature because of the immaturity of the thermoregulatory center. The difference between excessive warming and disease fever The above methods are for reference only, as the causes of fever are different and individual differences in performance are often different. Correct and timely detection of abnormalities in baby’s body temperature not only helps us to detect abnormalities in babies early, early detection and early treatment of diseases, but also helps to scientifically and effectively carry out baby’s warmth care to help babies grow up healthy and happy!
