Background: Immobility during hospital stay is associated with muscle weakness, delirium, and delayed neurocognitive recovery. Early mobilisation of critically ill adults improves their physical functioning and shortens the duration of mechanical ventilation. However, comparable research in children is lacking., Aims: To determine the effects of the implementation of an early mobilisation (EM) program on mobility activities for critically ill children and to explore barriers and facilitators and clinical outcomes before and after implementation., Study Design: A prospective single-centre before-and-after study. This study was conducted in a PICU of a large tertiary hospital. Children aged from 3 months to 18 years, with an expected stay of ≥3 days were eligible to participate. In the "before" phase, participants received usual care; in the "after" phase we implemented a multicomponent, multidisciplinary EM protocol. The primary outcome was a change in the process outcome "mobilisation activities". Secondary outcomes were PICU staff opinions on mobilisation (survey), safety, process measures, involvement of parents and physical therapist, and clinical outcomes (sedative use and prevalence of delirium)., Results: A total of 113 children were included; 55 before and 58 after, with a median age of 31 months (IQR: 10-103) and 35 months (IQR: 7-152), respectively. The number of mobilisation activities (per patient per day) had significantly increased from 5 (IQR: 2-7) to 6 (IQR: 4-8) (U = 272185.0; p < .001). PT consultations for mobilisation had significantly increased from 23.6% (13/55) to 46.5% (27/58) (X 2  = 6.48; p = .011). In both phases, no mobilisation-related adverse events were documented. The survey showed that PICU staff found EM of critically ill children useful and feasible. In the after phase, PICU staff rated the perceived benefit of the support of the physical therapist during mobilisation activities significantly higher than in the before phase (X 2  = 34.80; p < .001)., Conclusions: Implementation of a structured EM program for critically ill children is feasible and safe., Relevance to Clinical Practice: It is suggested to start the implementation of a structed EM program with the idendentification of local barriers and facilitators by an interdisciplinary PICU team. Further, an increased presence of physiotherapists on the PICU would improve mobilisation levels, and facilitate mobilisation in critically ill children. Also, they can support and advice PICU nurses and parents in mobilising children., (© 2022 The Authors.

Background: Widespread variation exists in pediatric critical care nutrition practices, largely because of the scarcity of evidence to guide best practice recommendations., Objective: The 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., Methods: A 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., Results: Forty-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., Conclusions: This 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., (© 2018 American Society for Parenteral and Enteral Nutrition.)

Background: Parenteral and enteral amino acid requirements for nutrition balance and function have not been defined in critically ill children or adults. In addition to playing a role in protein synthesis, amino acids trigger signaling cascades that regulate various aspects of fuel and energy metabolism and serve as precursors for important substrates. Amino acids can also be toxic. In this study, parenteral intakes of essential and nonessential amino acids (EAAs and NEAAs) supplied to critically ill children were assessed as an initial step for further studies aimed at establishing parenteral amino acid requirements., Methods: A retrospective review was conducted to assess intakes of parenteral amino acid for 116 critically ill children, and these intakes were compared with EAA intakes recommended by the Institute of Medicine. Because there are no recommended intakes for NEAA, NEAA intakes were compared with mixed muscle protein content in the older children and breast milk amino acid content in the infants., Results: Parenteral EAAs were provided in amounts that exceeded recommended intakes for healthy children, except for phenylalanine and methionine, which although excessive, were given in less generous amounts. NEAAs were supplied in lower or higher amounts than the content of mixed muscle proteins or breast milk. Parenteral amino acid formulas are limited in taurine, glutamine, and asparagine despite the fact that inflammatory/immune proteins are rich in these amino acids., Conclusions: Amino acid composition of parenteral formulas is variable and lacks scientific support. Parenteral amino acid intakes should be based on measured requirements to maintain nutrition and functional balance and on knowledge of toxicity.
