Comparing a new skin temperature sensor with ear and bladder thermometers in very elderly patients during leg bone surgery

The SpotOn sensor demonstrated a bias of 0.07°C ± 0.58°C compared to bladder temperature measurements in elderly patients undergoing lower extremity surgery.

• Core body temperature regulation may be compromised under anesthesia, particularly in elderly patients.
• The SpotOn sensor provides a noninvasive method for continuous temperature monitoring at the skin surface.
• This study involved 45 patients aged over 80 years, examining the accuracy of the SpotOn sensor against two other reliable temperature measurement methods.
• The SpotOn sensor showed acceptable agreement with bladder and tympanic membrane thermometers, with biases of 0.07°C and -0.28°C, respectively.
• Results indicate that the SpotOn sensor is feasible for measuring body temperature in the target population.
