It is usually believed that the normal axillary body temperature of newborns is 36~37 ℃, the anal temperature can be about 0.5 ℃ higher than the axillary temperature, and at the same time need to be analyzed in conjunction with the specific circumstances, such as measurement of a long time or breastfeeding and other circumstances such as measurement, the body temperature can be slightly higher.
In general, in a quiet state, measure the axillary temperature for 5 minutes, the normal temperature is 36 ~ 37 ℃, the measurement method is more commonly used in clinical practice. The use of anal surface thermometer to measure anal temperature can be about 0.5 ℃ higher than the axillary temperature, but in the clinical application of less.
For newborns, the temperature center of the nervous system is not well developed, susceptible to a variety of factors, such as measurement time is longer, higher temperatures in the peripheral environment, or in the crying or breastfeeding, can affect the measurement of the body temperature value, so that the measured body temperature increases, sometimes up to 37.5 ℃.
For an occasional slightly higher temperature, the general condition is good, no obvious discomfort, it is not considered abnormal for the time being, and need to be closely observed. It is recommended to consult a specialist for evaluation and judgment if necessary.
