Interdependence of exchangeable sodium and plasma renin concentration in determining blood pressure in patients treated by maintenance dialysis.

Plasma renin concentration and exchangeable sodium were measured in 13 patients with terminal renal failure maintained by dialysis therapy. Blood pressure in seven "responsive" patients was controlled by ultrafiltration but was not controlled in six "resistant" patients. Plasma renin concentration was inversely related to exchangeable sodium in the… CONTINUE READING
