Abstract

We compared an infrared temporal artery thermometer with our clinical standard axillary thermometer for temperature measurements in neonatal patients.  We measured temporal artery (T ), axillary (T , clinical standard), and rectal (T , gold standard) temperatures of 49 infants. The difference between T and T was compared with that between T and T , and the data were analyzed based on bed type and postmenstrual age.  The mean T , T , and T were 37.16 (SD 0.36) °C, 36.61 (SD 0.30) °C, and 36.82 (SD 0.30) °C, respectively. The measurements by these methods were all significantly different. The mean T -T was 0.21 (SD 0.26) °C, and the mean T -T was -0.34 (SD 0.37) °C, indicating that T was closer to T than was T (  < 0.0001). T agreed more closely with T for infants in cribs than for those in incubators. Adjusting for bed type and body weight, with each week of postmenstrual age, the discrepancy between T -T and T -T decreased by 0.005°C (  = 0.034).  Compared with the gold standard, T , T is not more accurate than T . The temporal artery thermometer was less accurate for infants in incubators than for infants in cribs. The accuracy of temporal artery temperature increased with postmenstrual age.
