The Effect of Amytal on the Cardiac Output and Peripheral Resistance of Man

Abstract
Measurements of cardiac output and intra-arterial pressure on 5 normal young men and 5 hypertensive patients before and during sedation with Amytal demonstrated a decreased cardiac output and an increased peripheral resistance during the period of sedation. It is concluded that the theoretic basis for the use of Amytal sedation as a device for selection of hypertensive patients for sympathectomy is not valid.
