Explain how nutrition therapy recommendations for an AKI patient may differ if he is receiving CRRT versus not receiving any dialysis treatment

What will be an ideal response?


• Higher protein needs; CRRT can remove amino acids and proteins, so a minimum protein intake of 1.5 g/kg/day is recommended (up to 2.0 g/kg/day if hypercatabolic).
• There does not need to be a fluid restriction with CRRT as it removes 1-2 L per day; with no dialysis, it is urine output plus 500 mL (very minimal to avoid fluid accumulation).
• Vitamin replacement may be necessary because of the loss of water-soluble vitamins with CRRT.
• If the patient was not receiving any dialysis, he would not tolerate fluid or protein as these would contribute to the major complications of AKI.
