Children undergoing anaesthesia are prone to hypothermia. Perioperative monitoring of patient temperature is, therefore, standard practice. Postoperative temperature is regarded as a key anaesthetic performance indicator in Australian hospitals. Many different methods and sites of temperature measurement are used perioperatively. It is unclear to what degree these methods might be interchangeable. The aim of this study was to determine the relationships between temperatures measured at different sites in anaesthetised children. Two hundred children, 0 to 17 years, undergoing general anaesthesia for elective non-cardiac surgery, were prospectively recruited. Temperature measurements were taken in the operating theatre concurrently at the nasopharynx, tympanic membranes, temporal artery, axilla and skin (chest). Patient age and weight were documented. Temperatures varied according to site of measurement. The mean difference from nasopharyngeal temperature to temperatures at left and right tympanic, temporal, axillary and cutaneous sites were +0.24°C, +0.24°C, +0.35°C, -0.38°C and -1.70°C, respectively. Levels of agreement to nasopharyngeal temperature were similar at tympanic, temporal and axillary sites. Tympanic and temporal temperatures were superior to axillary temperatures for detection of mild hypothermia (<36°C). Skin temperature showed a large variation from nasopharyngeal measurements. Our findings indicate that measured temperatures vary between sites. Understanding these variations is important for interpreting temperature readings.
接受麻醉的儿童容易出现体温过低。因此，围手术期对患者体温进行监测是标准做法。在澳大利亚的医院，术后体温被视为麻醉表现的关键指标。围手术期使用了许多不同的体温测量方法和部位。目前尚不清楚这些方法在多大程度上可以相互替代。本研究的目的是确定麻醉儿童不同部位测得的体温之间的关系。前瞻性招募了200名0至17岁接受择期非心脏手术全身麻醉的儿童。在手术室同时测量鼻咽、鼓膜、颞动脉、腋窝和皮肤（胸部）的温度。记录患者的年龄和体重。体温因测量部位而异。从鼻咽温度到左、右鼓膜、颞部、腋窝和皮肤部位温度的平均差值分别为+0.24°C、+0.24°C、+0.35°C、-0.38°C和-1.70°C。鼓膜、颞部和腋窝部位与鼻咽温度的一致性水平相似。鼓膜和颞部温度在检测轻度体温过低（<36°C）方面优于腋窝温度。皮肤温度与鼻咽测量值差异较大。我们的研究结果表明，不同部位测得的体温有所不同。了解这些差异对于解读体温读数很重要。
