whereas adrenalin and noradrenaline show differential effectivity in producing the local reactions ( the former more potent as a precapillary vasoconstrictor , promoting hct drop due to fluid inflow in the portal and hepatic vein , the latter more so in the renal vein and the aorta ) , adrenalin is invariably more effective in producing the second phase dilatory reaction with fluid outflow ( hct rise ) .
