What is the normal range for axillary temperature in a term newborn?

The normal range for axillary temperature in a term newborn is 97.7° F to 99.5° F. This range is established based on the physiology of newborns, who can be sensitive to fluctuations in temperature.

Axillary temperatures are typically lower than core temperatures measured rectally, thus establishing a range that reflects the expected thermal balance for a newborn is crucial. The chosen range ensures that monitoring and evaluation of a newborn’s temperature provide an appropriate indication of their overall thermal regulation and wellness.

In newborn care, maintaining normothermia is essential, as deviations can indicate potential health issues. The range defined by 97.7° F to 99.5° F captures typical homeostatic responses while allowing for slight variations due to external environmental influences or individual metabolism.
