Infrared axillary thermometers offer safe, rapid temperature readings for newborns. Accuracy is good for infants in cribs or incubators, but less reliable for those under radiant warmers.

Area of Science:

  • Neonatal care
  • Medical device technology
  • Temperature measurement

Background:

  • Accurate temperature monitoring is crucial for neonates.
  • Traditional methods can be invasive or time-consuming.
  • Infrared (IR) thermometers offer potential for rapid, non-invasive temperature assessment.

Purpose of the Study:

  • To evaluate the clinical accuracy of an IR thermometer for measuring axillary skin temperatures (AT) in neonates.
  • To compare AT measurements with rectal temperatures (RT) in term and premature infants under different environmental conditions.

Main Methods:

  • Axillary skin temperatures (AT) were measured using an IR thermometer (Lightouch Neonate, Exergen Corp).
  • RT was used as the reference standard.
  • Measurements were taken in 16 term infants under radiant warmers (RW) and in cribs, and in 12 premature infants in incubators.

Main Results:

  • For term infants in cribs and premature infants in incubators, mean RT-AT differences were minimal (0.25°C and 0.09°C, respectively), indicating good agreement.
  • Under radiant warmers, RT-AT differences in term infants showed wider variability, limiting clinical usefulness in this specific setting.

Conclusions:

  • IR axillary thermometry approximates rectal temperatures in term infants in cribs and stable premature infants in incubators.
  • The clinical utility of this IR thermometer is limited for term neonates under radiant warmers due to wider temperature variations.
