"Core" temperature and the proper methods for its assessment and management in cardiac surgical patients with hypothermia continues to be a concern for physicians and nurses. In this study we investigated the relationship between pulmonary artery and urinary bladder temperatures over a 6-hour period during rewarming in 14 (adult) patients in the intensive care unit after cardiopulmonary bypass. Bladder temperatures were 0.1 degree C to 0.2 degree C higher than pulmonary artery temperature with correlation coefficients of 0.94 to 0.99. This relationship continued for most of this period with significant mean differences clustering in the early and late period after admission. The significance of these small differences of temperatures and why the two temperatures reversed at certain time periods needs further investigation because the normal thermal gradients may be altered by the hypermetabolic activities consequent to shivering or iatrogenic overheating.
对于心脏外科低温患者，“核心”体温及其评估和管理的恰当方法一直是医生和护士所关注的问题。在本研究中，我们调查了14名（成年）重症监护病房患者在体外循环后复温6小时期间肺动脉温度和膀胱温度之间的关系。膀胱温度比肺动脉温度高0.1摄氏度至0.2摄氏度，相关系数为0.94至0.99。在这段时间的大部分时间里，这种关系持续存在，入院后早期和晚期存在显著的平均差异。这些微小温度差异的意义以及为何两个温度在特定时间段会反转，需要进一步研究，因为正常的热梯度可能会因颤抖或医源性过热导致的高代谢活动而改变。
