脑状态指数与双频指数在临床麻醉深度监测中的对比研究

Comparative Evaluation of Encephalon State Index and Bispectral Index in Monitoring the Depth of Anesthesia during the Surgical Anesthesia Stage

目的 对比双频指数(bispectral index, BIS),探究脑状态指数(encephalon state index, ESI)在临床麻醉深度监测中的性能。方法 通过单中心临床试验,采集60名患者脑状态指数(ESI)和双频指数(BIS)的数据,对比分析两者在临床麻醉深度监测中的一致性、相关性和预测概率(prediction probability, Pk)。结果一致性分析显示:脑状态指数(ESI)和双频指数(BIS)在清醒和麻醉状态下的均值差和标准差分别为-0.18±5.42,-0.11±6.51。相关性分析显示:在整个手术期间的相关性为0.92。预测概率:ESI与BIS的预测概率均为0.97,能很好地预测麻醉状态。结论 ESI和BIS在麻醉手术中具有较好的等效性,能够有效满足临床的麻醉监测需求。

Objective Evaluate the performance of the encephalon state index(ESI)in depth of anesthesia monitoring during clinical surgery,compared with the bispectral index(BIS).Methods ESI and BIS data were collected from 60 patients in a single-center clinical trial to compare their efficacy in measuring the depth of anesthesia.Results Consistency analysis revealed mean differences and standard deviations of-0.18±5.42 and-0.11±6.51 between ESI and BIS for awake and anesthetized states,respectively.Correlation analysis showed a correlation coefficient of 0.92 throughout the operative period.Prediction probability analysis indicated that both ESI and BIS had prediction probabilities of 0.97,effectively predicting anesthesia status.Conclusion ESI and BIS show good equivalence in monitoring depth of anesthesia during clinical surgery,which meet the requirements of clinical anesthesia.
