We have developed a controler system of sequential Hi/LO sodium concentration (144-134 mEq/1) in dialyzate for single pass method.
It was possible that in fact dialyzate sodium concentrations wave removed little by little and serum sodium slowly.
During benodialysis using this system, no trouble, such as dialysis disequilibrium syndrome was occured.
The merit of this system were the following:
(1) We don't need the I. V. infusion solution.
(2) The ultrafiltration rate was maintained above its desired level.
(3) No side-effect was found after dialysis such as hypertension.
(4) It is easy for us to treat this system in dialysate single pass method.
