Direct Actions of Volatile Anesthetics on the Coronary Vasculature
Blood vessels determine the distribution of cardiac output to the various body organs, and successful performance of this function necessitates a high degree of regulation of the vascular system. These regulatory processes involve both neurohumoral factors under nervous system control, and local control of vascular resistance within each bed being perfused. Thus, when attempting to understand the mechanisms of vascular action of hemodynamically active drugs such as halothane, it is important to distinguish their direct vascular effects (mediated by direct interaction of the anesthetic with the blood vessel) from their indirect vascular actions.
