Doses as high as what have been advocated to promote positive nitrogen balance in CRRT?

• A. 2.5 g/kg/day
• B. 1.5 g/kg/day
• C. 2.0 g/kg/day
• D. 3.0 g/kg/day

Answer: (A)

During CRRT, nitrogen is continually lost into the effluent, pushing the patient toward a negative nitrogen balance. To counter this, protein intake is increased to offset these losses. Doses up to about 2.5 g/kg/day have been advocated to promote a positive nitrogen balance in CRRT, providing a balance between meeting amino acid needs and avoiding excessive metabolic burden. Higher targets, like 3.0 g/kg/day, are less clearly supported by evidence and may add unnecessary risk, while lower targets may fail to compensate for CRRT-related losses.
