摘　　要：针对麻醉深度监测设备计量检测和性能评价方法缺失的问题,提出采用临床采集的真实脑电信号评价麻醉深度指数测量结果的方法。利用自制麻醉深度监测设备检测系统,将青年和老年患者的麻醉状态脑电信号输入BIS指数、CSI指数、Ai指数等三种麻醉深度监测设备,对测量结果的一致性和重复性进行了计算和评估,分析了指数与脑电信号频谱的相关性。三种指数在反映麻醉状态变化的整体趋势上有较好的一致性,但在麻醉过渡状态和老年患者样本的情况下表现出显著差异。结果表明该方法可用于三种麻醉深度监测设备的检测,对开展麻醉深度监测设备计量质控具有一定的指导意义。To address the lack of calibration and performance evaluation methods for anesthetic depth monitoring devices,a new approach is proposed that utilizes real clinical electroencephalogram(EEG)signals to assess the measurement results of anesthetic depth indices.Using a custom-built anesthetic depth monitoring device testing system,EEG signals from young and elderly patients under anesthesia were input into three anesthetic depth monitoring devices,namely BIS index,CSI index,and Ai index.The consistency and repeatability of the measurement results were calculated and evaluated,and the correlation between the indices and the EEG signal spectrum was analyzed.The three indices showed good overall consistency in reflecting the changes in anesthetic state,but significant differences were observed during the anesthetic transition state and in samples from elderly patients.The results indicate that this method can be used for testing the three anesthetic depth monitoring devices and provides guidance for conducting metrological quality control of these devices.
