Description
- Patients on chronic dialysis are susceptible to hypocalcaemia and an attempt is made to provide a positive calcium balance to prevent renal osteodystrophy,
- In the setting of renal failure requiring dialysis, 61% of calcium is not bound to plasma proteins and is in a diffusible equilibrium during hemodialysis. As a result calcium may be lost in a calcium free dialysate up to 40 mg/l (1.0 mmol/L)
- This is be prevented by adding calcium into the dilute dialysate at 1.75 mmol/L, or 7.0 mg/dl or giving calcium intravenously at the same rale it is being lost. Reductions in lonized calcium have been linked to increased vascular instability during hemodialysis
The composition of the dialysis solution is as follows:
PART 1: The acid concentrate (in liquid form) is composed of the following components in each 1000ml,
Sodium Chloride: 165.00g, Potassium Chloride: 6.00g. Magnesium Chloride: 3.70g, Acetic Acid: 9.509. HOOS
PART II: The bicarb concentrate part containing Sodium Bicarbonate 660.0g, Sodium Chloride 240,0g
Procedure for use:
Part I supplied in liquid form in white jerry cans of 10 its Part II supplied in polythene bags of 900 geach (2 packs are supplied) The total contents of part II are dissolved in purified water. The operator manual of the individual dialysis machine should be followed to obtain the final dialysate options based on a compatible concentrate-pair and standard proportioning ration to give a final solution by mixing 1/1,83:34 parts of part 1: part II purfied water
