Plasma atrial natriuretic peptide during hemodialysis with or without fluid removal.
Plasma immunoreactive human atrial natriuretic peptide (hANP) levels were measured in 9 patients with chronic renal failure treated with maintenance hemodialysis in order to evaluate the effects of fluid removal and osmotic pressure. Under hemodialysis without fluid removal plasma hANP levels remained unchanged, but the levels were significantly decreased during extra-corporeal ultrafiltration (p less than 0.01). The present study provided strong evidence that the fall in plasma hANP levels in hemodialysis patients is mainly due to the reduction in circulating plasma volume.
