全麻腹部手术患者围术期鼓膜温与腋温的变化研究

Study on the Changes of Perioperative Tympanic Membrane Temperature and Axillary Temperature in Patients Undergoing Abdominal Surgery under General Anesthesia

目的:研究全麻腹部手术患者围术期鼓膜温与腋温的变化规律。方法:选择笔者所在医院2018年5月-2019年1月择期全麻腹部手术患者40例,入手术室后均同时进行鼓膜温和腋温监测,麻醉诱导后每间隔20 min记录一次。观察麻醉诱导后180 min内不同时间点鼓膜温与腋温的变化情况。并采用Bland-Altman分析法对鼓膜温与腋温的一致性进行分析。结果:麻醉诱导后鼓膜温和腋温均随时间的变化而进行性下降,差异有统计学意义(F=67.617,P=0.000)。Bland-Altman分析显示,鼓膜温与腋温之间存在一致性,具有良好的相关性。结论:腹部手术患者全身麻醉后体温会下降,无线温度持续监测传感器测量鼓膜温,可以用于围术期体温的监测。

Objective:To study the changes of perioperative tympanic membrane temperature and axillary temperature in patients undergoing abdominal surgery under general anesthesia.Method:From May 2018 to January 2019,40 patients with abdominal surgery under general anesthesia in our hospital were selected.After entering the operating room,the tympanic membrane temperature and the axillary temperature were monitored at the same time.After induction of anesthesia,the tympanic membrane temperature and the axillary temperature were recorded every 20 min.The changes of tympanic membrane temperature and axillary temperature at different time points within 180 min after induction of anesthesia were observed.Bland-Altman analysis was used to analyze the consistency of tympanic membrane temperature and axillary temperature.Result:After induction of anesthesia,the temperature of tympanic membrane and axillary gradually decreased with the change of time.the difference was statistically significant(F=67.617,P=0.000).Bland-Altman analysis showed that the tympanic membrane temperature was consistent with the axillary temperature,showed a good correlation.Conclusion:The temperature of patients undergoing abdominal surgery will decrease after general anesthesia,and the continuous wireless temperature monitoring sensor measures the tympanic membrane temperature,which can be used for perioperative temperature monitoring.
