Effects of Ethyl Alcohol on Cardiac Output and Its Distribution in the Rat. ∗

Abstract

Summary and conclusions

(1) Ethyl alcohol does not influence cardiac output of the rat in doses of 5 ml of 20% by volume solution in 200-250 g rats. (2) Blood flow values to the major organs calculated from the fractional uptake of Rb⁸⁶ or iodoantipyrine (I¹³¹) show the following: cutaneous blood flow (considering the skin as a whole) hepatic arterial inflow, portal flow other than splenic, and bronchial blood flow are unaffected by alcohol; coronary blood flow is increased 31%; renal blood flow is reduced 32%; cerebral blood flow is 90% greater in the alcohol treated than in the pentobarbitalized animal.
