Hypertension is a disease with increasing and serious complications all over the world. In particular, the incidence of hypertension increases with advancing age. Secondary problems that can be caused by hypertension include peripheral vascular diseases, arteriosclerosis, increased risk of heart attack and stroke. It is a measurement of pulse wave velocity (PWV), a non-invasive indicator of arterial stiffness. It is known that sudden hemodynamic changes that occur during the induction of anesthesia cause undesirable intraoperative and postoperative complications. It is known that arterial stiffness, which is more common in elderly patients, causes orthostatic hypotension in particular. For this reason, more hemodynamic instability may be seen in the general anesthesia procedure in elderly patients with increased arterial stiffness. In our study, we aimed to investigate whether the hemodynamic changes observed during anesthesia induction in hypertensive elderly patients, whom we think have a high pulse wave velocity, are different from normotensive patients.

After resting in a quiet room preoperatively, blood pressure was measured on the right arm using an oscillometric method.

Difference between hemodynamic values
The difference between the hemodynamic values measured preoperatively and during anesthesia induction was calculated. In addition, ≥20% decrease in preoperative hemodynamic value and/or systolic blood pressure ≤90 mmHg hypotension, ≥20% increased hypertension
Time frame: Basal measurement before induction of anesthesia, then at 1-minute intervals until after endotracheal intubation
