Forehead skin temperature measured by a stip of liquid-crystal material was compared to esophageal, rectal, and axillary temperatures measured by thermistor probes in patients having general anesthesia for coronary artery bypass grafting. Before extracorporeal circulation, forehead skin temperature was lower than axillary, rectal, and esophageal temperatures by approximately 2.2 C (4.0 F). During rapid warming, forehead skin temperature rose concurrently with the other temperatures measured but remained significantly different. The liquid-crystal strip may be useful as a safe, convenient method for routine monitoring of temperature trends during general anesthesia in patients whose exact core temperature need not be continuously monitored. We believe that infants, patients undergoing extracorporeal circulation, major abdominal, vascular, or neurosurgical procedures, or patients with a history of temperature regulatory problem are probably best monitored by a method which more exactly reflects core temperature.
在接受冠状动脉搭桥术全身麻醉的患者中，将通过液晶材料条测量的额头皮肤温度与通过热敏电阻探头测量的食管、直肠和腋窝温度进行了比较。在体外循环前，额头皮肤温度比腋窝、直肠和食管温度低约2.2摄氏度（4.0华氏度）。在快速升温期间，额头皮肤温度与其他测量温度同时上升，但仍存在显著差异。液晶条可作为一种安全、方便的方法，用于在不需要连续监测确切核心温度的全身麻醉患者中常规监测温度趋势。我们认为，婴儿、接受体外循环的患者、进行大型腹部、血管或神经外科手术的患者，或有体温调节问题病史的患者，可能最好通过更准确反映核心温度的方法进行监测。
