Body temperature readings provide vital information for accurate diagnoses and required therapies. However, standard practices for measuring body temperature in intensive care units (ICUs) vary and often require invasive methods with limited accuracy in different types of patients.
Schell-Chaple and colleagues evaluated a new, noninvasive monitoring system that is applied to the lateral forehead, called SpotOn. They compared temperatures taken with the SpotOn system with rectal and bladder temperatures in febrile adult patients. They found the following:
Most of the noninvasive forehead temperatures and the rectal and bladder temperatures were within ±0.5°C.
No signs of skin irritation were noted after 4½ hours of forehead temperature monitoring.
The SpotOn method was accurate. Although the authors recommend further research to test for longer periods, they suggest this noninvasive system be considered for continuous monitoring of core temperature in ICU patients.
