Objective:
To assess the efficacy of temporal artery thermometer in febrile and hypothermic neonates in comparison to axillary thermometer.
Methods:
It was a cross sectional observational study. Study participants included 210 neonates admitted in neonatal intensive care unit of a tertiary care teaching hospital, divided into three groups of 70 each, namely normothermic, febrile and hypothermic. Temperatures were measured using temporal artery, axillary and rectal thermometers in each patient.
Results:
Mean rectal temperature was found to be comparable to mean temporal artery temperature in normothermic babies. Temporal artery thermometer had a better sensitivity to diagnose fever, than hypothermia. Also, temporal artery temperature showed a good correlation with rectal temperature in normothermic and febrile group and not in hypothermic neonates.
Conclusions:
Temporal artery thermometer can accurately detect temperature in febrile and normothermic fullterm neonates but not in hypothermic neonates. Further studies are required before advocating temporal artery thermometry as a replacement of rectal thermometry among this group of population.

Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
