NOTE: Always consider citrate toxicity if calcium compensation > 100% calcium "gap" >2.5 or worsening acidaemia.
Potassium Supplementation in Renal Replacement (PRISMA)
|Plasma potassium conc||Add to 51 standard dialysate & replacement fluid solution||Final dialysate & replacement fluid K+ conc.|
|>6.0 mmol/L||Nil to first bag and repeat serum K+ at 4 hours||0 mmol/L|
|3.0 – 6.0||20 mmol||4 mmol/L|
If potassium supplementation exceeds that described above, it should be given parenterally in the normal way until a desired serum potassium concentration is achieved.
