Energy balance
Critically ill patients require significantly higher protein intakes (2.0–2.5 g/kg/day) than standard guidelines (1.2–1.5 g/kg/day) to achieve positive nitrogen balance and potentially improve survival.
For critically ill patients without kidney failure, medical teams should consider protein intakes of 2.0–2.5 g/kg/day. This higher dose is necessary to counteract the severe catabolic state of critical illness and achieve positive nitrogen balance, which may support survival.
Hoffer and Bistrian have recommended protein provision of 2–2.5 g/kg/day for critically ill patients (66, 67). This level of protein intake is rationalized by these authors as being necessary to offset the sharp negative nitrogen balances seen in critically ill patients (66, 67).
Why this rating
Based on observational data and nitrogen balance studies; the paper notes a lack of large clinical trial support for survival benefits specifically from protein alone.
