Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The incidence of postoperative delirium at discharge or within 5 days after surgery; | — |
Secondary
| Measure | Time frame |
|---|---|
| Assess the Pittsburgh Sleep Quality Index score from postoperative day 1 to day 5 (before discharge);Hospital Anxiety and Depression Scale score;Postoperative pain score;Changes in inflammatory factors related to postoperative delirium compared to preoperative levels;Evaluate Charlson's comorbidity index score;Assessment of Consciousness Status (Delirium assessment method) Score;Integrating brain structure and functional imaging through functional magnetic resonance imaging (fMRI) and EEG techniques, dynamically observing the time-varying mapping relationship of brain functional activity intensity, and evaluating changes in fiber bundle structure connections and functional connections between the hippocampus and prefrontal cortex; | — |
