Moreover, the effects of dopemine on renal function hew not yet bee” clearly elucidated. The aim of this study “-2 :c the systemic, splsnchnic and evaluate renal hemodynemic effects of low doses - dopaminergic in patients vieh cirrhosis. dose - of dopamine Nine cirrhotic patients vith ascites received Plasme 1.5 &kg.min of dopemine for 30 min. dopamlne kVelB rose from 35?20 to 31400?14900 pressure gradient and pRImI. h;patic biood flov were not affe-cted whereas ~zwos blood ilou cinrrlfi,antlv increased from O.Z*O.lj to 0.99tO.i8 l/min.

It is concluded that dopaminergic dose of dopamine acts on renal hemodynamics and ha8 no deleterious effect on portal hypertension ir: patients with cirrhosis.
