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.

Objectives: In children, coronavirus disease 2019 is usually mild but can develop severe hypoxemic failure or a severe multisystem inflammatory syndrome, the latter considered to be a postinfectious syndrome, with cardiac involvement alone or together with a toxic shock like-presentation. Given the novelty of severe acute respiratory syndrome coronavirus 2, the causative agent of the recent coronavirus disease 2019 pandemic, little is known about the pathophysiology and phenotypic expressions of this new infectious disease nor the optimal treatment approach. Study Selection: From inception to July 10, 2020, repeated PubMed and open Web searches have been done by the scientific section collaborative group members of the European Society of Pediatric and Neonatal Intensive Care. Data Extraction: There is little in the way of clinical research in children affected by coronavirus disease 2019, apart from descriptive data and epidemiology. Data Synthesis: Even though basic treatment and organ support considerations seem not to differ much from other critical illness, such as pediatric septic shock and multiple organ failure, seen in PICUs, some specific issues must be considered when caring for children with severe coronavirus disease 2019 disease. Conclusions: In this clinical guidance article, we review the current clinical knowledge of coronavirus disease 2019 disease in critically ill children and discuss some specific treatment concepts based mainly on expert opinion based on limited experience and the lack of any completed controlled trials in children at this time.

The aim of the present study was to describe the present knowledge of healthcare professionals and the practices surrounding enteral feeding in the UK and Irish paediatric intensive care unit (PICU) and propose recommendations for practice and research. A cross-sectional (thirty-four item) survey was sent to all PICU listed in the Paediatric Intensive Care Audit Network (PICANET) database (http://www. picanet.org.uk) in November 2010. The overall PICU response rate was 90 % (27/30 PICU; 108 individual responses in total). The overall breakdown of the professional groups was 59 % nursing staff (most were children's nurses), 27 % medical staff, 13 % dietitians and 1 % physician assistants. Most units (96 %) had some written guidance (although brief and generic) on enteral nutrition (EN); 85 % of staff, across all professional groups (P¼ 0·672), thought that guidelines helped to improve energy delivery in the PICU. Factors contributing to reduced energy delivery included: fluid-restrictive policies (60 %), the child just being 'too ill' to feed (17 %), surgical post-operative orders (16 %), nursing staff being too slow in starting feeds (7 %), frequent procedures requiring fasting (7 %) and haemodynamic instability (7 %). What constituted an 'acceptable' level of gastric residual volume (GRV) varied markedly across respondents, but GRV featured prominently in the decision to both stop EN and to determine feed tolerance and was similar for all professional groups. There was considerable variation across respondents about which procedures required fasting and the duration of this fasting. The present survey has highlighted the variability of the present enteral feeding practices across the UK and Ireland, particularly with regard to the use of GRV and fasting for procedures. The present study highlights a number of recommendations for both practice and research.

This paper highlights the dearth of research related to enteral feeding in critically ill children. We found that the use of feeding guidelines improved calorie delivery and so units should be encouraged to develop their own guidelines based on the best evidence available.

Wide variations in practices exist in the nutritional care between European PICUs, which reflects the absence of local protocols and scientific society-endorsed guidelines. This is likely to contribute to suboptimal energy delivery in this particularly vulnerable group.

Critically ill children frequently fail to achieve adequate energy intake, and some care practices, such as the measurement of gastric residual volume (GRV), may contribute to this problem. We compared outcomes in two similar European Paediatric Intensive Care Units (PICUs): one which routinely measures GRV (PICU-GRV) to one unit that does not (PICU-noGRV). An observational pilot comparison study was undertaken. Eighty-seven children were included in the study, 42 (PICU-GRV) and 45 (PICU-noGRV). There were no significant differences in the percentage of energy targets achieved in the first 4 days of PICU admission although PICU-noGRV showed more consistent delivery of median (and IQR) energy targets and less under and over feeding for PICU-GRV and PICU-noGRV: day 1 37 (14–72) vs 44 (0–100), day 2 97 (53–126) vs 100 (100–100), day 3 84 (45–112) vs 100 (100–100) and day 4 101 (63–124) vs 100 (100–100). The incidence of vomiting was higher in PICU-GRV. No necrotising enterocolitis was confirmed in either unit, and ventilator-acquired pneumonia rates were not significantly different (7.01 vs 12 5.31 per 1000 ventilator days; p = 0.70) between PICU-GRV and PICU-noGRV units. Conclusions: The practice of routine gastric residual measurement did not significantly impair energy targets in the first 4 days of PICU admission. However, not measuring GRV did not increase vomiting, ventilator-acquired pneumonia or necrotising enterocolitis, which is the main reason clinicians cite for measuring GRV. What is known: • The practice of routinely measuring gastric residual volume is widespread in critical care units • This practice is increasingly being questioned in critically ill patients, both as a practice that increases • The likelihood of delivering inadequate enteral nutrition amounts and as a tool to assess feeding tolerance What is new: • Not routinely measuring gastric residual volume did not increase adverse events of ventilator acquired pneumonia, necrotising enterocolitis or vomiting. • In the first 4 days of PICU stay, energy target achievement was not significantly different, but the rates of under and over feeding were higher in the routine GRV measurement unit.

BackgroundMeasuring gastric residual volume (GRV) to guide enteral feeding is a common nursing practice in intensive care units, yet little evidence supports this practice. In addition, this practice has been shown to potentially contribute to inadequate energy delivery in intensive care, which remains a problem in critically ill children.. AimsWe aimed to explore paediatric intensive care nurses' decision-making surrounding this practice. MethodsA cross-sectional electronic survey in a single mixed general and cardiac surgical PICU in the UK. ResultsThe response rate was 59% (91/154) and responding nurses were experienced, with a mean PICU experience of 10.5 years (SD 8.09). The three main reasons for stopping or withholding enteral feeds were: the volume of gastric residual volume obtained (67%), the appearance of this gastric aspirate (40%) and the overall clinical condition of the child (23%). Most 2 nurses reported checking GRV primarily to determine 'feed tolerance' (97%) as well as confirming feeding tube position (94%). Nurses' perceived harms from high GRV were: the risk of pulmonary aspiration (44%), malabsorption of feeds (20%) and the risk of vomiting (19%). GRV was measured frequently in this PICU, with 58% measuring GRV before every feed, 27% measuring 4 hourly and 17% measuring 6 hourly.The majority of nurses (84%) stated they would be worried or very worried if they could not measure GRV routinely. ConclusionsPICU nurses' decision-making surrounding initiating and withholding enteral feeds, and determining 'feed tolerance' remains heavily based on GRV. PICU nurses' have significant fears around patient harm if they do not measure GRV routinely. Relevance to clinical practiceThis nursing practice is likely to be one of the factors that impair the delivery of enteral nutrition in critically ill children and as such its validity and usefulness needs to be challenged and studied in future research.

Objective: To explore enteral feeding practices and the achievement of energy targets in children on Non-invasive respiratory support (NRS), in four European Pediatric Intensive Care Units (PICUs).
