摘　　要：为了实现当前脑电双频谱指数(Bispectral index, BIS)监测仪对神经重症患者的动态化监测,研究对其内部麻醉监测架构进行改进,提出了优化的BIS监测仪,并对其有效性进行了验证。结果表明,研究提出的框架在麻醉监测上相对于使用LSTM网络模型的框架提升最高达到15%左右,预测准确性最高。而在实际应用中,麻醉前后动脉血压的差距为6%~14%,而体温变化维持在0.9℃~1.6℃之间,术后心率的变化同样维持在1.3~4.4次/分、血氧饱和度差距仅在0.4%~0.5%,BIS指数分数差距为5~12分之间。同时其在麻醉诱导、维持以及苏醒上的精确性分别为58.1%、96.0%以及56.6%,整体上准确率达到了90.1%,综合性能最好。综合来看,研究提出的改进的BIS监测仪在麻醉深度监测上具备较高的有效性,对神经重症患者护理具有重要意义。In order to achieve dynamic monitoring of neurological critical patients using the current BIS monitor,an improved internal anesthesia monitoring architecture was studied,and an optimized BIS monitor was proposed and its effectiveness was verified.The results indicate that the framework proposed in the study has higher accuracy in anesthesia monitoring,with an overall improvement of about 0.74%,and has the highest predictive accuracy and stability.In practical application,the difference of arterial blood pressure before and after anesthesia is 6%~14%,while the change of body temperature is maintained between 0.9℃~1.6℃,the change of heart rate after surgery is also maintained between 1.3~4.4 times/min,the difference of oxygen saturation is only 0.4%~0.5%,and the difference of BIS index score is between 5~12 points.At the same time,its accuracy in anesthesia induction,maintenance,and awakening was 58.1%,96.0%,and 56.6%,respectively,with an overall accuracy of 90.1%and the best overall performance.Overall,the improved BIS monitor proposed in the study has high effectiveness in monitoring anesthesia depth and is of great significance for the care of critically ill patients with neurological disorders.
