Correlation Between Perioperative Autonomic Function and Adverse Events Such as Post-induction Hypotension in Elderly Patients
Elderly patients have a higher risk of post-induction hypotension (PIH). The decreased cardiovascular autonomic function at baseline in elderly patients may contribute to the development of PIH. The objective of our study is to effect of preoperative cardiovascular autonomic modulation in PIH, we will recruit elderly patients who are going to have general anesthesia surgery and measure preoperative baroreflex sensitivity (BRS) and heart rate variability (HRV). The primary outcome will be PIH. Secondary outcomes included: early intraoperative hypotension, postoperative complications, and 30-day postoperative mortality.
