Abstract
Methods are provided for preparing a ready-to-use peritoneal dialysis fluid for peritoneal dialysis of a patient. The methods comprise mixing, immediately before administration to the patient, appropriate amounts of at least a first concentrate and a second concentrate with an appropriate amount of water to form a ready-to-use dialysis fluid. The first concentrate comprises glucose and has a pH of between 1.5 and 4; and the second concentrate comprises a physiologically acceptable buffer and sodium ions, and has a pH of between 5.0 and 9.0. The ready-to-use dialysis fluid has a sodium ion concentration of about 110 mM to about 145 mM and an osmolality of about 0.20 to about 0.50 Osm/kg.

A method for preparing a ready-to-use peritoneal dialysis fluid for peritoneal dialysis of a patient, the method comprising:
- mixing, before administration to the patient, appropriate amounts of at least a first concentrate and a second concentrate with an appropriate amount of water to form a ready-to-use dialysis fluid,
- wherein the first concentrate includes glucose, has a pH of between 1.5 and 4, and is free of sodium ions,
- wherein the second concentrate includes a physiologically acceptable buffer and sodium ions, and has a pH of between 5.0 and 9.0, and
- wherein the ready-to-use dialysis fluid has a sodium ion concentration of about 110 mM to about 145 mM and an osmolality of about 0.20 to about 0.5 Osm/kg.
A method for preparing a ready-to-use peritoneal dialysis fluid for peritoneal dialysis of a patient, the method comprising:
- mixing, before administration to the patient, appropriate amounts of at least a first concentrate and a second concentrate with an appropriate amount of water to form a ready-to-use dialysis fluid,
- wherein the first concentrate is free of sodium ions, and
- wherein the second concentrate includes sodium ions.
A system for preparing a ready-to-use peritoneal dialysis fluid for peritoneal dialysis of a patient, the system comprising:
- a proportioning device or cycler;
- at least one source of water adapted for connection with the proportioning device or cycler;
- at least one source of the first concentrate adapted for connection with (i) the proportioning device or cycler and (ii) the source of water, wherein the first concentrate is free from sodium ions;
- and
- at least one source of the second concentrate adapted for connection with (i) the proportioning device or cycler and (ii) the source of water.
