SensorTouch is a new noninvasive temperature monitor and consists of an infrared scanner that detects the highest temperature on the skin of the forehead, presumably over the temporal artery. The device estimates core temperature (T(core)). 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 37.8 degrees C, after cardiopulmonary bypass. Temperature was recorded at 15-min intervals throughout recovery with the SensorTouch thermometer and from the pulmonary artery (adults) or bladder (children). Pulmonary artery (T(core)) and SensorTouch (T(st)) temperatures correlated poorly in adults: T(core) = 0.7. T(st) + 13, r(2) = 0.3. Infrared and pulmonary artery temperatures differed by 1.3 +/- 0.6 degrees C; 89% of the adult temperatures thus differed by more than 0.5 degrees C. Bladder and infrared temperatures correlated somewhat better in pediatric patients: T(core) = 0.9. T(st) + 12, r(2) = 0.6. Infrared and bladder temperatures in children differed by only 0.3 degrees C, but the SD of the difference was 0.5 degrees C. Thus, 31% of the values in the infants and children differed by more than 0.5 degrees C.
We evaluated a noninvasive infrared forehead thermometer (SensorTouch) in adult and pediatric cardiac patients. Accuracy was poor in the adults and suboptimal in infants and children.
SensorTouch是一种新型无创体温监测仪，由一个红外扫描仪组成，该扫描仪可检测前额皮肤（大概是颞动脉上方）的最高温度。该设备可估算核心体温（T(core)）。我们检验了SensorTouch在常规临床应用中足够精确和准确的假设。我们研究了在体外循环后出现低热（核心体温至少37.8摄氏度）的成人（n = 15）和儿童（n = 16）。在整个恢复过程中，每隔15分钟用SensorTouch温度计记录一次体温，并从肺动脉（成人）或膀胱（儿童）记录体温。成人的肺动脉（T(core)）和SensorTouch（T(st)）温度相关性较差：T(core) = 0.7×T(st) + 13，r(2) = 0.3。红外温度和肺动脉温度相差1.3±0.6摄氏度；因此，89%的成人温度相差超过0.5摄氏度。儿科患者的膀胱温度和红外温度相关性稍好：T(core) = 0.9×T(st) + 12，r(2) = 0.6。儿童的红外温度和膀胱温度仅相差0.3摄氏度，但差值的标准差为0.5摄氏度。因此，31%的婴幼儿和儿童的值相差超过0.5摄氏度。
我们在成人和儿科心脏患者中评估了一种无创红外前额温度计（SensorTouch）。其在成人中的准确性较差，在婴幼儿和儿童中也不理想。
