composition of dialysate fluid
Last reviewed 01/2018
The composition of dialysis fluid used varies according to clinical need. A standard solution aims to allow a net outflow of potassium from the blood, at a rate below that to create hypokalaemia, and a net inflow of calcium. The difficulties of producing bicarbonate containing dialysate fluid have largely been overcome so that it is no longer necessary to use acetate instead.
A typical composition would be:
mmol / l
- sodium 140.0
- potassium 1.0
- calcium 1.25
- bicarbonate 34.0
- magnesium 0.5
- chloride 107.5
- glucose 5.5
