Methods and Devices of Temperature Measurement in the Neonate: A Narrative Review and Practice Recommendations

There are a number of measurement devices available for use. However agreement about the effectiveness of the various types of thermometers in the neonatal population remains unclear. The review indicates that the axilla method continues to be the site of choice for preterm and term infants. However, it has been noted in some studies that very little work has been done on the sensitivity and specificity of each method of temperature measurement, making it difficult to identify any negative or positive results in relation to measuring temperature at the axilla, rectal, skin, forehead and tympanic sites. Nurses need to be aware of the various temperature measurement methods, devices and factors influencing neonatal temperature recordings. New thermometers should be rigorously tested for suitability in the neonatal population. Evidence based practice remains important and studies need to continue into the accuracy and reliability of different temperature measurement devices and methods.
