Abstract

Relative cardiovascular stability has been found to be one of the major advantages of epidural anesthesia and, depending on the nature of the case, a moderate degree of hypotension may be tolerated before a correction becomes necessary. However, if the arterial pressure declines, it may be difficult to compensate for the dilated vascular bed resulting from sympathetic paralysis by means of fluid substitution alone. Impairment of circulatory compensatory mechanisms, activated by a decrease in perfusion pressure, may necessitate immediate treatment if the venous return is restricted by a loss of effective blood volume from hemorrhage or by postural pooling in regions of vasodilatation.
