Abstract

Infusion of 0.75 μg/kg bw/min norepinephrine (NE), for 40 minutes, into one renal artery in anesthetized dogs, induced acute renal failure (ARF). Subsequently there was nearly complete reversal of function within 8 weeks. Isotonic saline volume expansion, or renal vasodilation plus diuresis by acetylcholine (into renal artery: 20 μg/min), did not protect against this type of ARF. Volume expansion with either 5 or 20 percent mannitol partly prevented the fall of GFR 3 hours after NE, this protection being correlated with the magnitude of the osmolar clearance at the time of the insult. IV furosemide (10 mg/kg + 10 mg/kg/h; fluid losses replaced) afforded an even better protection. Proximal tubular necrosis in the 'protected' kidneys was as severe as in non-protected kidneys. Glomerular cell morphology (scanning electron microscopy) was not altered by the 40-minute NE infusions. Functional 'protection' appeared to depend on solute diuresis at the time of insult.
