Key result
Infusion of a physiological dose of ANP in dogs decreased renal blood flow from 3.28 to 3.03 ml.min-1.g-1 (P<0.01) without affecting the glomerular filtration rate.
Why the study?
Does a physiological dose of ANP affect renal function in anesthetized dogs?
Does a physiological dose of ANP affect renal function in anesthetized dogs?
Absolute Event Rate: 3.03% vs 3.28%
p-value: p=<0.01
A physiological dose of ANP induces natriuresis and diuresis and modestly decreases renal blood flow without affecting true GFR, though clearance methods may overestimate GFR under these conditions.

May modestly decrease RBF without affecting GFR in dogs; leaves open translation to human cardiorenal physiology.
R. O. Banks (1988) studied this question. Atrial natriuretic peptide (ANP, 8-33) vs. Baseline control period was evaluated on Renal blood flow (RBF) (p=<0.01). Infusion of a physiological dose of ANP in dogs decreased renal blood flow from 3.28 to 3.03 ml.min-1.g-1 (P<0.01) without affecting the glomerular filtration rate.
