[Pulse wave velocity can predict hemodynamic responses to induction of anesthesia and tracheal intubation].
BACKGROUND
The degree of aortic stiffness can be evaluated by noninvasive measurement of pulse wave velocity (PWV). We investigated hemodynamic responses to induction of anesthesia and tracheal intubation, and hypothesized that preoperative measurement of PWV might predict these responses.


METHODS
PWV was measured before operation by using automatic PWV measurement device. Patients were anesthetized with fentanyl (1 microg x kg(-1)) and propofol (target controlled infusion at 2.5 microg x ml(-1)), and tracheal intubation was facilitated with vecuronium (1.5 mg x kg(-1)). Hemodynamic data were recorded from the start of anesthesia to 5 minutes after the tracheal intubation.


RESULTS
Twenty patients completed the study. There was a significant correlation between PWV and percent changes in systolic blood pressure during anesthesia induction. However, a significant correlation between PWV and percent changes in systolic blood pressure after tracheal intubation was found only in the patients without antihypertensive medications.


CONCLUSIONS
Preoperative PWV measurement was useful to predict hemodynamic responses to induction of anesthesia and tracheal intubation.
