Abstract

The autonomic nervous system (ANS) is of vital importance in regulating cardiovascular homeostasis. Most anesthetics, muscle relaxants, and surgical stimulus modulate ANS. Therefore, evaluation of the impact of anesthetics on ANS is important to determine subsequent compensatory responses of the cardiovascular system. Among the tests to assess ANS function are the measurement of heart rate variations during Valsalva maneuver, heart rate responses to postural changes, deep breathing, and pharmacological intervention, and blood pressure responses to postural changes or to sustained handgrip. These measurement cannot be clinically practical during anesthesia and surgery to monitor ANS activity.
