Abstract

We examined the acute systemic and renal hemodynamic effects of intravenous meglumine/sodium diatrizoate-76% and iopamidol in euvolemic and dehydrated dogs. The physiologic responses were compared with acute changes in the level of an endogenous heparin-like material (EHM). One of eight dehydrated dogs receiving diatrizoate (2 ml/kg) had an immediate vomiting reflex associated with a very significant decline in all measured renal hemodynamic parameters; none of eight dehydrated dogs receiving iopamidol experienced a similar reaction. EHM levels did not correspond to the magnitude of the physiologic responses follow-ing either iopamidol or diatrizoate. Significant differences between iopamidol and diatrizoate were noted when comparing the magnitude of the decrease in systemic pressure (- A 3.8 ± 3.02, iopamidol, n = 8; vs. - A 19.4 ± 7.3 mm Hg, diatrizoate, n = 8; P <.03), increased renal plasma flow (+ A 6.2 ± 4.9, iopamidol, n=8; vs. 4- A 33.7 ±8.0 ml/min, diatrizoate, n = 8;P<.05), and decreased filtration fraction (- A 0.09 ± 0.01, iopamidol, n = 8; vs. - A 0.14± 0.02, diatrizoate, n = 8;P<.03). There was no significant difference in the decrease in glomerular filtration rate (- A 7.4 ± 1.0, iopamidol, n = 8; vs. - A 9.3 ± 1.3, diatrizoate, n = 8; P >.05), since the marked drop in filtration fraction occurring with diatrizoate was counterbalanced by the marked increase in renal plasma flow. Acute systemic and renal hemodynamic effects are significantly lessened when comparing iopamidol with diatrizoate.
