HOMEOSTASIS OF SODIUM IN NEPHROPATHY DOGS UNDER INFUSION OF DOPAMINE

Abstract

Dopamine is an endogenous compound widely used in intensive care. It has a broad spectrum of actions on both cardiovascular and urinary system. Increased glomerular filtration rate, renal blood flow and fractional excretion of sodium are expected renal effects in normal individuals, but are little used in veterinary medicine. With the aim to assess the homeostasis of sodium in nephropathy dogs, this study was conducted. Different doses of dopamine were administered in nephropathy dogs. Laboratory evaluations were performed during and after the treatments. The creatinine clearance and fractional excretion of sodium showed dose-dependent increase in healthy dogs. Nephropathy dogs, both dose slightly increased the GFR, but did not alter the fractional excretion of sodium and blood pressure.
