Patients aged 65 years or older scheduled for general anesthesia with tracheal intubation will undergo preoperative physical activity monitoring using an ActiGraph wearable accelerometer. Activity-related parameters, including sedentary time, light-, moderate-, and vigorous-intensity activity, daily step count, and sleep duration, will be recorded. Cardiovascular autonomic function will be assessed perioperatively using noninvasive continuous hemodynamic monitoring, with baroreflex sensitivity-related indices derived from continuous blood pressure and beat-to-beat timing data. The primary outcome is post-induction hypotension. Secondary outcomes include early intraoperative hypotension, postoperative complications, and 30-day mortality. This study aims to clarify the relationship between habitual physical activity and autonomic regulation in older surgical patients and to provide evidence supporting future prehabilitation strategies.",[55],"Post Induction Hypotension",[57,58,59],"post induction hypotension","elderly patient","wearable accelerometer","2026-06-01",{"date":62,"type":63},"2026-06-02","ACTUAL",{"date":65,"type":50},"2026-06-15",{"date":67,"type":50},"2027-12-31",{"name":5,"class":6},1]
