The management of intravenous (IV) fluid temperature is a daily challenge in critical care, anesthesiology, and emergency medicine. Infusion of IV fluids at the right temperature partly influences clinical outcomes of critically ill patients. Nowadays, intravenous fluid temperature is poorly managed, as no suitable device is routinely available. Infrared (IR) thermometers have been recently developed for industrial, personal, or medical purposes. The aim of this study was to evaluate the accuracy of an IR thermometer in measuring temperature of warmed and cooled infusion fluids in fluid bags.
This study compared temperatures simultaneously recorded by an infrared thermometer and a temperature sensor. Temperatures of warmed (41 degrees C) and cooled (4 degrees C) infusion fluids in fluid bags were recorded by 2 independent operators every minute until IV bags' temperature reached ambient temperature.
The relation curve was established with 576 measures. Temperature measures performed with an IR thermometer were perfectly linear and perfectly correlated with the reference method (R(2) = 0.995, P < 10(-5)).
Infrared thermometers are efficient to measure IV fluid bag temperature in the range of temperatures used in clinical practice. As these devices are easy to use and inexpensive, they could be largely used in critical care, anesthesiology, or emergency medicine.
在重症监护、麻醉学和急诊医学中，静脉输液温度的管理是一项日常挑战。输注温度适宜的静脉输液在一定程度上会影响重症患者的临床结局。目前，静脉输液温度管理不善，因为没有常规可用的合适设备。红外温度计最近已被开发用于工业、个人或医疗用途。本研究的目的是评估一种红外温度计在测量输液袋中温热和冷却的输液温度时的准确性。
本研究比较了红外温度计和温度传感器同时记录的温度。两名独立操作人员每分钟记录一次输液袋中温热（41摄氏度）和冷却（4摄氏度）的输液温度，直至输液袋温度达到环境温度。
通过576次测量建立了关系曲线。用红外温度计进行的温度测量呈完美的线性，且与参考方法高度相关（R² = 0.995，P < 10⁻⁵）。
红外温度计在临床实践所用的温度范围内能有效地测量静脉输液袋温度。由于这些设备易于使用且价格低廉，它们可广泛应用于重症监护、麻醉学或急诊医学。
