What is the consensus daily protein delivery for patients undergoing CRRT?

• A. 1.5-2 g/kg/day
• B. 0.5-1 g/kg/day
• C. 1.0-1.5 g/kg/day
• D. 2.0-2.5 g/kg/day

Answer: (A)

CRRT increases daily protein losses and accelerates catabolic energy use, so protein needs are higher to maintain lean body mass and nitrogen balance. The recommended daily protein delivery for patients on CRRT is about 1.5 to 2 g/kg/day. This amount accounts for ongoing amino acid losses in the effluent and the hypercatabolic state of critical illness, providing enough substrate for tissue repair and immune function without overloading metabolism. Lower ranges (0.5–1 g/kg/day or 1.0–1.5 g/kg/day) typically fall short of offsetting CRRT-related losses and the stress of critical illness, risking negative nitrogen balance. A higher range (2.0–2.5 g/kg/day) may exceed what’s necessary for most patients and could introduce unnecessary nitrogen burden or metabolic complications. In practice, targets are adjusted based on CRRT dose, inflammation, and tolerance, with monitoring of nitrogen balance and metabolic parameters.
