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.

Abstract

Preoperative moderate-to-vigorous physical activity is associated with a significantly reduced risk of postoperative delirium in patients with silent brain infarction. Findings indicate that postoperative delirium severity is self-limiting, with symptoms resolving rapidly within 3 days after surgery. Surgery time and intra-operative hypothermia are significant mediating factors in this association.
