What Causes Low Blood Pressure After Anesthesia in Older Adults Having Non-Heart Surgery ?

This intervention refers to the standard induction of general anesthesia in geriatric patients undergoing elective non-cardiac surgery. Induction typically involves the administration of intravenous anesthetic agents such as propofol and fentanyl, based on institutional protocols and the anesthesiologist's discretion. This study does not modify or introduce any new treatment; it merely observes and records peri-induction parameters to identify factors associated with the occurrence of post-induction hypotension.

This intervention involves the standard clinical use of non-invasive continuous blood pressure monitoring during the induction of general anesthesia in geriatric patients undergoing elective non-cardiac surgery. Intravenous anesthetic agents (e.g., propofol, fentanyl) and vasopressors (e.g., ephedrine, norepinephrine) are administered via syringe pumps based on the anesthesiologist's clinical judgment. The study does not introduce any experimental treatment but observes blood pressure changes in real time to identify risk factors for post-induction hypotension. The integration of continuous hemodynamic monitoring distinguishes this observational approach from routine anesthetic induction without such monitoring.
