Abstract:
:The intravascular contrast media in current use are solutions of salts of tri-iodinated substituted benzoic acids. Haemodynamic changes following injection of these contrast media are due mainly to their high osmolar concentration which is five to eight times physiological levels. In this study we compare the effect in dogs on femoral arterial flow following femoral arterial injection of three new low osmolality contrast media (Amipaque, Iopamidol and Hexabrix) compared to conventional contrast media (Coronary 280). Conventional salts such as Conray 280 cause a marked vasodilatation and increase in femoral blood flow to about twice pre-injection levels. The three new low osmolality contrast media cause much less vasodilation and increase in femoral blood flow (+32%). There was no significant difference between the effects of any of the three new media. The experiment suggests that any of three new low osmolality contrast media should be suitable for femoral arteriography as they cause much less vasodilatation (and therefore discomfort) than conventional contrast media. Our results do not indicate a preference for any of the three new contrast agents.
