Association between preoperative physical exercise and postoperative delirium in silent brain infarction

Key Points

• The study aims to investigate the impact of preoperative physical exercise on the incidence of postoperative delirium in individuals with silent brain infarction.
• Analyzed the relationship between preoperative physical activity levels and postoperative delirium outcomes.
• Monitored severity and resolution of delirium symptoms within 3 days post-surgery.
• Investigated mediating factors such as surgery duration and intra-operative hypothermia.
• Preoperative moderate-to-vigorous physical activity significantly lowers the risk of postoperative delirium.
• Delirium symptoms tend to resolve quickly, usually within 3 days after surgery.
• Surgery time and intra-operative hypothermia significantly influence the relationship between exercise and delirium.
