Three methods of temperature monitoring were studied in 55 adult hypothermic postcardiac surgery patients using the pulmonary artery, rectum, and urinary bladder as measurement sites. Pulmonary artery temperature served as the standard for core body temperature. Measurements in the rectum were recorded with a disposable plastic temperature probe and in the urinary bladder with a thermistor-tipped Foley catheter. Patients were studied within one hour of admission to the cardiac surgical intensive care unit and on an hourly basis until they reached normothermia (37 degrees C). Although mean temperatures did not vary greatly for any group, there was a significant difference between measures over time. Correlations of pulmonary artery and urinary bladder temperatures ranged from .78 to .94, pulmonary artery and rectal temperature from .49 to .82, and urinary bladder and rectal temperature from .46 to .85. The results of this study indicate that the urinary bladder is a reliable indicator of core temperature during rewarming following cardiac surgery.
在55例心脏手术后体温过低的成年患者中，研究了三种温度监测方法，测量部位分别为肺动脉、直肠和膀胱。肺动脉温度作为核心体温的标准。直肠温度用一次性塑料温度探头记录，膀胱温度用带热敏电阻的Foley导管记录。在患者入住心脏外科重症监护病房后一小时内进行研究，并每小时进行一次，直至体温恢复正常（37摄氏度）。尽管任何一组的平均温度变化不大，但随着时间的推移，测量结果存在显著差异。肺动脉与膀胱温度的相关性在0.78至0.94之间，肺动脉与直肠温度的相关性在0.49至0.82之间，膀胱与直肠温度的相关性在0.46至0.85之间。本研究结果表明，在心脏手术后复温过程中，膀胱是核心体温的可靠指标。
