Abstract
SensorTouch is a new noninvasive temperature monitor which consists of an infrared scanner that detects the highest temperature on the skin of the forehead, presumably over the temporal artery. From this value, the device estimates core temperature (Tcore). We tested the hypothesis that the SensorTouch is sufficiently precise and accurate for routine clinical use. We studied adults (n = 15) and children (n = 16) who developed mild fever, a core temperature of at least 37.8C, after cardiopulmonary bypass. Temperature were recorded at 15 minute intervals throughout recovery with the SensorTouch thermometer and from the pulmonary artery (adults) or bladder (children). Pulmonary artery (Tcore and SensorTouch (Tst temperatures correlated poorly in adults: Tcore = 0.6. Tst + 18, r2 = 0.2. Infrared and pulmonary-artery temperatures differed by 1.3 + or - 0.6C; 89% of the adult temperatures thus differed by more than 0.5C. Bladder and infrared temperatures correlated somewhat better in pediatric patients; Tcore = 0.9. Tst + 12, r2 = 0.6. Infrared and bladder temperatures in children differed by only 0.3C, but the standard deviation of the difference was 0.5C. Thus 31% of the values in the infants and children differed by more than 0.5C.
