@entity349 -in-glass thermometers are considered the "gold-standard" for temperature measurements, but require at least 4 minutes for accuracy. Electronic thermometers sample temperature measurements over a shorter period. The objective of this study was to evaluate the accuracy and reproducibility of the Penguin (Medisim, Jerusalem, Israel) and the IVAC (San Diego, CA) Temp plus II thermometers in preterm @entity1 . Axillary temperature was obtained in 50 thermally stable preterm @entity1 each time with the @entity349 -in-glass, the IVAC, and the Penguin thermometers. Analysis of variance F-test, and linear regression analyses were used to test correlation of each electronic thermometer with the @entity349 -in-glass one, and the effect of body weight. Temperature measurement taken with the Penguin thermometer was significantly higher than that measured with the two other ones, p < 0.001. The differences in means and in variances were not significantly different between IVAC and @entity349 -in-glass, while the variance of the Penguin measurement was higher than that of the two other instruments (p < 0.001). The IVAC instrument correlated more tightly with the @entity349 -in-glass (r = 0.89, p < 0.001) than did the Penguin (r = 0.54, p < 0.001). There was an inverse correlation between the deviation of the Penguin measurement from the @entity349 -in-glass and the weight of the @entity1 ( p < 0.08), while no significant correlation was found between the deviation of the IVAC measurement from the @entity349 in glass and the @entity1 's weight (p = 0.56). Measurements of axillary temperature using the Penguin thermometer in incubated preterm @entity1 are less accurate and less reproducible than those obtained using the IVAC or the glass thermometers.
