Objective: The aim of this study was to investigate correlations between measurements taken with four different thermometer devices in four different neonatal temperature sites and determine the optimal site of measuring temperature in neonates. Design: Prospective, over an 18 month period. Participants: Four hundred (400) neonates with gestational age 37–42 weeks. Methods: The temperature measurements were performed using mercury-in-glass thermometer, a digital thermometer, a tympanic thermometer and an infrared forehead thermometer. Paired t test, Interclass Correlation Coefficient (ICC) and the Bland-Altman plot were used to compute data. Results: The mean temperature of neonates was 36,77±0, 44°C and 36,65±0, 36°C with a mercury-in-thermometer in rectum and axilla respectively, 36,79±0, 46°C and 36, 72±0, 36°C with a digital thermometer in rectum and axilla respectively, 36,63±0, 39°C with the tympanic thermometer and 36,73±0,39°C with the forehead thermometer. The mean difference with the mercury in glass and the digital thermometer was 0.02°C in rectum and 0.07°C in axilla (p<0,001). There was a strong correlation between the measurements with the mercury-in-thermometer and the digital thermometer in rectum and axilla (r=0.93 and 0.9 respectively and p<0,001). Conclusions: The optimal way to measure body temperature in neonates is rectally with a mercury-in-thermometer or digital. Reliable seem to be the axillary measurements using a mercury-in-glass thermometer or digital thermometer.
