Liquid crystal thermometry (LCT) is a non-invasive alternative to temperature monitoring. We evaluated the ability of forehead LCT, rectal temperature, and axillary skin temperature to trend distal oesophageal temperature during rapid warming on cardiopulmonary bypass. In 24 patients undergoing open heart surgery, temperatures were measured during the rapid warming phase on bypass (12-35 min). Scattergrams of temperature vs time for the four temperature sites each contained 150 data points. Polynomial regression analysis revealed that LCT, but not axillary or rectal temperatures, correlated with oesophageal temperature. We conclude that forehead LCT may be useful to monitor temperature trends and to detect rapid elevations in body temperature when more invasive temperature monitoring is inappropriate or unavailable.
液晶测温法（LCT）是一种用于体温监测的非侵入性方法。我们评估了在体外循环快速复温期间，前额LCT、直肠温度和腋窝皮肤温度追踪远端食管温度变化趋势的能力。对24例接受心脏直视手术的患者，在体外循环快速复温阶段（12 - 35分钟）测量体温。四个温度测量部位的温度与时间散点图各包含150个数据点。多项式回归分析显示，LCT与食管温度相关，而腋窝或直肠温度与食管温度不相关。我们得出结论，当更具侵入性的体温监测方法不适用或无法使用时，前额LCT可能有助于监测体温变化趋势并检测体温的快速升高。
