无线体温传感器监测日间手术术中核心体温的可行性:前瞻性诊断试验

Feasibility of iThermonitor for Intraoperative Monitoring the Core Body Temperature during Ambulatory Surgery: A Prospective Diagnostic Test

目的观察日间手术中采用无线体温传感器持续监测核心体温的有效性和可行性。方法前瞻性收集从2017年10月25日至2017年12月8日,在四川大学华西医院接受日间手术患者术中体温监测的数据,每组数据包括食管温度、直肠温度和无线体温传感器监测的腋窝温度。以食管温度为标准,计算腋窝温度及直肠温度与其差值,并分析二者与食管温度的一致性。结果共113例符合纳入和排除标准的患者入选本研究,采集到1451组体温监测数据。以食管温度为标准,腋窝温度较食管温度低(0.06±0.26)℃,而直肠温度较食管温度高(0.39±0.23)℃。相关分析显示腋窝温度(r=0.9331)较直肠温度(r=0.8431)更接近食管温度。腋窝温度在食管温度±0.5℃以内的比例为94.97%,而直肠温度为78.91%。结论无线体温传感器用于成人日间手术术中持续核心体温监测是有效可行的。

Objective The aim of this study was to observe the feasibility and effectiveness of iThermonitor for continuous monitoring of the core body temperature during ambulatory surgery.Methods The body temperatures of patients who underwent ambulatory surgery in West China Hospital from October 25 to December 8,2017 were prospectively collected.Each set of data included the esophageal temperature,rectal temperature,and armpit temperature measured by iThermonitor.The esophageal temperature was used as the standard and subtracted from the armpit temperature and rectal temperature,respectively.SAS and R softwares were used for consistent analysis.Results A total of 113 patients meeting the inclusive and exclusive criteria were enrolled in this study,and 1451 sets of intraoperative temperature data were collected.The armpit temperature measured by iThermonitor was(0.06±0.26)℃lower,while the rectal temperature was(0.39±0.23)℃higher than the esophageal temperature.In terms of the correlation coefficient,iThermonitor temperature(r=0.9331)was closer to the esophageal temperature than the rectal temperature(r=0.8431).In respect of the proportion of falling into the esophageal temperature±0.5℃,armpit temperature was 94.97%and the rectal temperature was 78.91%.Conclusion iThermonitor might be effectively used to monitor the core body temperature of adult patients during ambulatory surgery.
