[Study of the effect of dopamine on renal excretion in chronic renal failure (author's transl)].

The effects of dopamine on renal excretory function were studied in 20 patients with chronic renal failure (plasma creatinine higher than 30 mg/i). Effects were marked at a dose of 2 micrograms/kg/mn and were no greater at a dose of 5 micrograms/kg/mn (10 subjects in each case). In general, creatinine clearance increased by 28%, urea excretion by 45%, urine output by 77% and urinary sodium output by 164%. In ten patiens with terminal renal failure (plasma creatinine greater than 100 mg/i), the effects of dopamine were maintained. In these individuals, furosemide (250 mg by single intravenous injection) resulted in a higher total urine and urinary sodium output but had a less favourable effect upon creatinine.
