研究目的: |
在接受Trendelenburg 体位的腹部大手术患者中,量化术中动态脑自动调节受损的累积负荷(DCA%),并验证其是否为术后谵妄(POD)的独立预测因子;解析 DCA%与POD风险之间的剂量-反应关系特征,识别导致风险显著跃升的临床报警阈值(Cut-off value);评估DCA%对术后住院时间、拔管时间等整体转归的影响。 |
||||||||||||||||||||||
|
Objectives of Study: |
In patients undergoing major abdominal surgeries in the Trendelenburg position, quantify the cumulative load of impaired dynamic cerebral autoregulation during the operation (DCA%), and verify whether it is an independent predictor of postoperative delirium (POD); Analyze the dose-response characteristics of the relationship between DCA% and the risk of POD, identify the clinical alarm threshold (Cut-off value) that leads to a significant increase in risk; Evaluate the impact of DCA% on overall outcomes such as postoperative hospital stay and extubation time. |
