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.
