ReviewParenteral nutrition in the ICU setting: need for a shift in utilization.
The difficulties to feed the patients adequately with enteral nutrition alone have drawn the attention of the clinicians toward the use of parenteral nutrition, although recommendations by the recent guidelines are conflicting. This review focuses on the intrinsic role of parenteral nutrition, its new indication, and modalities of use for the critically ill patients. ⋯ Parenteral nutrition can be used to substitute or supplement enteral nutrition, if adequately prescribed. Testing for enteral nutrition tolerance during 2-3 days after ICU admission provides the perfect timing to start parenteral nutrition, if needed. In case of absolute contraindication for enteral nutrition, consider starting parenteral nutrition carefully to avoid overfeeding.

This article describes the current best available evidence on optimal nutrition in the paediatric intensive care based on different levels of outcome, which can be divided in surrogate and hard clinical outcome parameters. ⋯ Until now, there are no randomized controlled trials which have investigated a causal relation between different feeding regimens on the nutritional status and short and long-term outcome. As a result current optimal nutritional strategies are based on small trials with surrogate outcome parameters. Prospective randomized studies are needed with nutritional and/or metabolic interventions to come to an optimal feeding strategy for critically ill children.

ReviewIs early starvation beneficial for the critically ill patient?
Anorexia is a preserved evolutionally response that may be beneficial during acute illness. Yet current clinical practice guidelines recommend early and targeted enteral nutritional support. However, the optimal timing of the initiation of enteral nutrition and the caloric and protein requirements of critically ill patients is controversial. ⋯ Limiting nutrient intake during the first 48-72 h of acute illness may be beneficial; in those patients who are unable to resume an oral diet after this time period intermittent enteral nutrition targeting 20-25 cal/kg/day is recommended.
