研究目的:

针对脓毒症相关性脑病(SAE)缺乏早期预警手段的临床难题,本项目旨在整合无创多模态脑功能监测技术,构建一个能够在典型神经症状出现前 24~72 小时预测 SAE 发生风险的动态预警模型,并通过前瞻性临床研究验证其效能,最终形成可临床转化的 “监测?预警?干预”一体化方案。  

Objectives of Study:

To address the clinical challenge of the lack of early warning methods for sepsis-associated encephalopathy (SAE), this project aims to integrate non?invasive multimodal brain function monitoring technologies to construct a dynamic early warning model capable of predicting the risk of SAE occurrence 24–72 hours before the appearance of typical neurological symptoms. The model's performance will be validated through a prospective clinical study, ultimately leading to the formation of a clinically translatable "monitoring?warning?intervention" integrated solution.
