Summary

Background:

Hypotension during the induction of anesthesia is a significant clinical condition associated with increased perioperative morbidity and mortality. This study aims to evaluate whether hypotension occurring during anesthesia induction can be predicted using arterial stiffness and stiffness index parameters measured by ultrasonography. Additionally, the study investigates potential associations between arterial stiffness parameters and intraoperative hemodynamic variables, vasoactive drug use, length of stay in the hospital and intensive care unit (ICU), and mortality.

Methods:

This prospective study was conducted in patients scheduled for elective open cardiac surgery. The predictive value of arterial stiffness, measured by ultrasonography, for identifying hypotension during anesthesia induction was assessed. Carotid-femoral pulse wave velocity (PWV) and stiffness index (β index) were used as indicators of arterial stiffness.

DIAGNOSTIC_TEST

Doppler ultrasonography

The delay time was determined as the time difference between the onset of the Doppler waveform and the R-wave on the electrocardiogram(ECG) of the USG device. The distance between the carotid and femoral arteries, where imaging was performed, was then measured. This distance was divided by the delay time to calculate the carotid-femoral pulse wave velocity(PWV) in meters per second, which was considered a measure of arterial stiffness.
