METHODS: This study compared axillary temperature with a urinary bladder thermometer in 40 major abdominal postoperative patients. The primary outcome was changes in axillary temperature registrations. Secondary outcomes were mean bias between the urinary bladder and the axillary temperatures. Intermittent frontal and tympanic temperature recordings were also collected.
RESULTS: Forty patients were monitored for 50 min with an average core temperature of 36.8 °C. The mean bias was -1.0 °C (LoA -1.9 to -0) after 5 min, and -0.8 °C (LoA -1.6 to -0.1) after 10 min when comparing the axillary temperature with the urinary bladder temperature. After 20 min, the mean bias was -0.6 °C (LoA -1.3-0.1). During upper arm abduction, the axilla temperature was reduced to -1.6 °C (LoA -2.9 to -0.3) within 1 min. Temporal skin temperature measurement had a resulted in a mean bias of -0.1 °C (LOA -1.1 to -1.0) compared with central temperature. Compared with the mean tympanic temperature, it was -0.1 °C (LoA -0.9 to -1.0) lower than the urinay bladder temperature.
CONCLUSIONS: Axillary temperature increased with time, reaching a mean bias of 1 °C between axillary and core temperature within 5 min. Opening the axillary resulted in rapidly lower temperature recordings. These findings may aid in use and designing corrections for continuous axillary temperature monitoring.
方法:本研究比较了40例腹部术后患者的腋窝温度和膀胱温度计。主要结果是腋窝温度记录的变化。次要结果是膀胱和腋窝温度之间的平均偏差。还收集了间歇性的额叶和鼓室温度记录。
结果:40名患者接受了50分钟的监测,平均核心温度为36.8°C。5分钟后,平均偏差为-1.0°C(LoA-1.9至-0),和-0.8°C(LoA-1.6至-0.1)后10分钟时,将腋窝温度与膀胱温度进行比较。20分钟后,平均偏差为-0.6°C(LoA-1.3-0.1).上臂外展时,腋窝温度在1分钟内降至-1.6°C(LoA-2.9至-0.3)。与中心温度相比,时间皮肤温度测量的平均偏差为-0.1°C(LOA-1.1至-1.0)。与平均鼓室温度相比,它比尿袋温度低-0.1°C(LoA-0.9至-1.0)。
结论:腋窝温度随时间增加,在5分钟内达到腋窝和核心温度之间的平均偏差为1°C。打开腋窝会导致温度迅速降低。这些发现可能有助于使用和设计用于连续腋窝温度监测的校正。
