Background: Nutritional support is considered essential for the outcome of paediatric critical illness. There is a lack of methodologically sound trials to provide evidence-based guidelines leading to diverse practices in PICUs worldwide. Acknowledging these limitations, we aimed to summarize the available literature and provide practical guidance for the paediatric critical care clinicians around important clinical questions many of which are not covered by previous guidelines. Objective:To provide an ESPNIC position statement and make clinical recommendations for the assessment and nutritional support in critically ill infants and children. Design: The metabolism, endocrine and nutrition (MEN) section of the European Society of Pediatric and NeonatalIntensive Care (ESPNIC) generated 15 clinical questions regarding different aspects of nutrition in critically ill children. After a systematic literature search, the Scottish Intercollegiate Guidelines Network (SIGN) grading system was applied to assess the quality of the evidence, conducting meta-analyses where possible, to generate statements and clinical recommendations, which were then voted on electronically. Strong consensus (> 95% agreement) and consensus (> 75% agreement) on these statements and recommendations was measured through modified Delphi voting rounds. Results:The final 15 clinical questions generated a total of 7261 abstracts, of which 142 publications were identified relevant to develop 32 recommendations. A strong consensus was reached in 21 (66%) and consensus was reached in 11 (34%) of the recommendations. Only 11 meta-analyses could be performed on 5 questions. Conclusions:We present a position statement and clinical practice recommendations. The general level of evidence of the available literature was low. We have summarised this and provided a practical guidance for the paediatric critical care clinicians around important clinical questions.There is a lack of high-quality evidence to guide nutrition in paediatric critical illness. This position statement and clinical recommendations summarise the existing evidence around 15 of the most important clinical questions, and where no evidence is available, suggest good clinical practice.

In critically ill children, TUN was elevated and REE was reduced during the entire period of mechanical ventilation. Minimum intakes of 1.5 g/kg/d of protein and 58 kcal/kg/d can equilibrate nitrogen and energy balances in children up to 4 years old. Older children require more protein.

BackgroundWidespread variation exists in pediatric critical care nutrition practices, largely because of the scarcity of evidence to guide best practice recommendations.ObjectiveThe objective of this paper was to develop a list of topics to be prioritized for nutrition research in pediatric critical care in the next 10 years.MethodsA modified 3‐round Delphi process was undertaken by a newly established multidisciplinary group comprising 11 international researchers in the field of pediatric critical care nutrition. Items were ranked on a 5‐point Likert scale.ResultsForty‐five research topics (with a mean priority score >3(0‐5) were identified within the following 10 domains: the pathophysiology and impact of malnutrition in critical illness; nutrition assessment: nutrition risk assessment and biomarkers; accurate assessment of energy requirements in all phases of critical illness; the role of protein intake; the role of pharmaco‐nutrition; effective and safe delivery of enteral nutrition; enteral feeding intolerance: assessment and management; the role of parenteral nutrition; the impact of nutrition status and nutrition therapies on long‐term patient outcomes; and nutrition therapies for specific populations. Ten top research topics (that received a mean score >4(0‐5) were identified as the highest priority for research.ConclusionsThis paper has identified important consensus‐derived priorities for clinical research in pediatric critical care nutrition. Future studies should determine topics that are a priority for patients and parents. Research funding should target these priority areas and promote an international collaborative approach to research in this field, with a focus on improving relevant patient outcomes.
