| Popis: | The authors compared the systemic hemodynamic and renal vascular effects of hypotension induced by fenoldopam with those produced by the most commonly used hypotensive agent, sodium nitroprusside, in 10 dogs. Mean arterial pressure decreased 26% +/- 3% from control following infusion with fenoldopam, and 30% +/- 2% following infusion with sodium nitroprusside (these decreases were not significantly different between the groups). Renal blood flow (RBF) was preserved during fenoldopam-induced hypotension (214 +/- 16 mL/min at baseline and 197 +/- 16 mL/min after fenoldopam-induced hypotension). In contrast, RBF decreased from 223 +/- 17 mL/min to 167 +/- 12 mL/min during sodium nitroprusside-induced hypotension (P less than 0.02). The differences in RBF between the two groups occurred in spite of the fact that cardiac output and pulmonary capillary wedge pressure were kept similar between the two groups. The authors conclude that fenoldopam, a selective dopamine1 (DA1) receptor agonist, preserves blood flow to the kidney during induced hypotension. On the other hand, sodium nitroprusside is a nonselective arteriolar and venous vasodilator that redistributes blood flow away from the kidneys during induced hypotension. |
