Effects of Dopamine and Epinephrine on Intestinal Blood Flow and Oxygen Uptake
The cardiovascular effects of dopamine (3,4-dihydroxyphenyl-ethylamine) have been studied by numerous investigators and because of its effects on splanchnic hemodynamics, dopamine has been suggested as a therapeutic agent in cardiovascular shock (1). In normal, anesthetized dogs and in shocked dogs, dopamine is a potent vasoconstrictor in the intestinal circulation (2,3), but the effects of dopamine on the delivery of oxygen to the gut are unknown.
