Esophageal, rectal, tympanic, and central blood temperature, i.e., pulmonary artery and aortic arch, were recorded in three patients during iatrogenic whole-body hyperthermia for the treatment of advanced malignant metastatic cancer. Aortic temperature closely followed changes in pulmonary arterial temperature, with an average delay time of 27 s. Esophageal temperature reflected quantitatively and more quickly (avg lag time, 80 s) the temperature changes in the pulmonary artery than tympanic membrane temperature. Tympanic temperature was consistently lower than the blood temperature of the heart during steady state. Therefore it is suggested that esophageal temperature is a preferable index of central blood temperature. Additionally, measurement of esophageal temperature can be made more easily and safely than tympanic membrane temperature.
在三名晚期恶性转移性癌症患者接受医源性全身热疗期间，记录了食管、直肠、鼓膜及中心体温（即肺动脉和主动脉弓处的体温）。主动脉温度紧密跟随肺动脉温度的变化，平均延迟时间为27秒。与鼓膜温度相比，食管温度能更快速（平均延迟时间为80秒）且定量地反映肺动脉的温度变化。在稳态时，鼓膜温度始终低于心脏的血液温度。因此，建议食管温度是中心体温的更优指标。此外，测量食管温度比测量鼓膜温度更容易、更安全。
