RESUMEN
Background: Stress cardiomyopathy (Takotsubo syndrome) defined as Takotsubo syndrome is defined as a reversible acute myocardial syndrome with myocardial injury with regional wall motion abnormality and no coronary explanations in the context of stress. The pathophysiology remains partially unknown, and these cases are probably underestimated in paediatrics. We report six cases of Takotsubo probably secondary to neurological damage. Case summary: Six patients (10, 13, 16, 10, and 9 years and 5 months) presented with haemodynamic lability with echocardiography data leading to suspicion of Takotsubo syndrome. These cases were secondary to neurological involvement (cerebral haemorrhage, intraventricular haemorrhage, brain damage due to bifrontal oedema, posterior fossa tumour, pneumococcal meningitis, high-grade glioma). All patients were rapidly started on amine. Reversibility of the acute myocardial syndrome was complete in all but one child, who rapidly progressed to encephalic death. Discussion: Neurological distress has been suggested as a potential cause of Takotsubo syndrome. The pathophysiology is possibly related to excessive stimulation of the sympathetic system. This syndrome should probably be considered in the setting of left heart failure with neurological distress so as not to delay the use of amines especially since in the paediatric population the probability of a coronary origin is low.
RESUMEN
OBJECTIVE: To reach a consensus on the definition and modalities of weaning from noninvasive ventilation in acute settings. DESIGN: A modified Delphi survey using closed and open-ended questions. SETTING: Three rounds of consensus determination were sent via electronic mail survey to 33 experts. The survey questionnaire had four sections: definition of weaning, definition of weaning failure, criteria to initiate weaning, and modalities of weaning. Questions where agreement had been reached on round 1 were no longer part of the survey in rounds 2 and 3. SUBJECTS: Twenty-five international experts from 10 countries. MEASUREMENT AND MAIN RESULTS: Overall, this survey generated positive consensus from experts for 19/35 statements (9 with strong agreement and 10 with weak agreement) about weaning from noninvasive respiratory support. No negative consensus could be identified. CONCLUSION: The clinical practice statements issued address important aspects of definition of weaning, definition of weaning failure, criteria to initiate weaning, and modalities of weaning in acute settings.

OBJECTIVES: Electrolyte disorders occurs frequently in children with bronchiolitis. The aim of the present study was to describe the frequency of hypophosphatemia and to evaluate its association with length of mechanical ventilation in infants admitted to a pediatric intensive care unit (PICU) with bronchiolitis. METHODS: This retrospective cohort study included infants aged between 7 days and 3 months admitted to a PICU between September 2018 and March 2020 and diagnosed with severe acute bronchiolitis requiring respiratory support. Infants with a chronic condition that could potentially be a confounding factor were excluded. The primary outcome was the frequency of hypophosphatemia (<1.55 mmol/L); the secondary outcomes were the frequency of hypophosphatemia during the PICU stay, and the association with length of mechanical ventilation (LOMV). RESULTS: Among the 319 infants admitted 178 had at least one phosphatemia value and were included in the study. The frequency of hypophosphatemia was 41% at PICU admission (61/148) and 46% during the PICU stay (80/172). The median [IQR] LOMV was significantly longer in children with hypophosphatemia at admission (109 [65-195] h vs. 67 [43-128] h, p = 0.007), and in multivariable linear regression lower phosphatemia at admission was associated with longer LOMV (p < 0.001) after controlling for severity (PELOD2 score) and weight. CONCLUSION: Hypophosphatemia was frequent in infants with severe bronchiolitis admitted to a PICU and was associated with a longer LOMV.

OBJECTIVES: The worldwide practice and impact of noninvasive ventilation (NIV) in pediatric acute respiratory distress syndrome (PARDS) is unknown. We sought to describe NIV use and associated clinical outcomes in PARDS. DESIGN: Planned ancillary study to the 2016/2017 prospective Pediatric Acute Respiratory Distress Syndrome Incidence and Epidemiology study. SETTING: One hundred five international PICUs. PATIENTS: Patients with newly diagnosed PARDS admitted during 10 study weeks. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Children were categorized by their respiratory support at PARDS diagnosis into NIV or invasive mechanical ventilation (IMV) groups. Of 708 subjects with PARDS, 160 patients (23%) received NIV at PARDS diagnosis (NIV group). NIV failure rate (defined as tracheal intubation or death) was 84 of 160 patients (53%). Higher nonrespiratory pediatric logistic organ dysfunction (PELOD-2) score, Pa o2 /F io2 was less than 100 at PARDS diagnosis, immunosuppression, and male sex were independently associated with NIV failure. NIV failure was 100% among patients with nonrespiratory PELOD-2 score greater than 2, Pa o2 /F io2 less than 100, and immunosuppression all present. Among patients with Pa o2 /F io2 greater than 100, children in the NIV group had shorter total duration of NIV and IMV, than the IMV at initial diagnosis group. We failed to identify associations between NIV use and PICU survival in a multivariable Cox regression analysis (hazard ratio 1.04 [95% CI, 0.61-1.80]) or mortality in a propensity score matched analysis ( p = 0.369). CONCLUSIONS: Use of NIV at PARDS diagnosis was associated with shorter exposure to IMV in children with mild to moderate hypoxemia. Even though risk of NIV failure was high in some children, we failed to identify greater hazard of mortality in these patients.

INTRODUCTION: Ventilator settings in children under anaesthesia remain difficult because of the changes in the physiology and the high dead space. OBJECTIVE: To determine the alveolar minute-volume to sustain normocapnia in children under mechanical ventilation. DESIGN: A prospective observational study. SETTINGS: This study was performed between May and October 2019 in a tertiary care children's hospital. PATIENTS: Children between 2âmonths and 12âyears, weighing between 5 and 40âkg, admitted for general anaesthesia. INTERVENTION: Volumetric capnography was used to estimate the alveolar and dead space volume (Vd). MAIN OUTCOME MEASURES: Total and alveolar minute ventilation in (mlâkg -1 âmin -1 ) over 100 breaths. RESULTS: Sixty patients were included comprising 20 per group: 5 to 10âkg (group 1), 10 to 20âkg (group 2), 20 to 40âkg (group 3). Seven patients were excluded for aberrant capnographic curves. After normalisation to weight, the median [IQR] tidal volume per kilogram was similar between the three groups: 6.5âmlâkg -1 [6.0 to 7.5âmlâkg -1 ], 6.4â mlâkg -1 [5.7 to 7.3â mlâkg -1 ], 6.4â mlâkg -1 [5.3 to 6.8â mlâkg -1 ]; P â=â0.3. Total Vd (in mlâkg -1 ) was negatively correlated to weight ( r â=â-0.62, 95% confidence interval -0.41 to -0.76, P â<â0.001). The total normalised minute ventilation (mlâkg -1 âmin -1 ) to obtain normocapnia was higher in group 1 than in group 2 and in group 3; 203â mlâkg -1 âmin -1 [175 to 219âmlâkg -1 âmin -1 ], 150â mlâkg -1 âmin -1 [139 to 181â mlâkg -1 âmin -1 ] and 128â mlâkg -1 âmin -1 [107 to 157â mlâkg -1 âmin -1 ]; P â<â0.001 (mean ± SD), but (mean ± SD) alveolar minute ventilation was similar between the three groups; 68â±â21â mlâkg -1 âmin -1 . CONCLUSION: Total dead space volume (including apparatus dead space) represents a major component of tidal volume in children less than 30âkg, when using large heat and moisture exchanger filters. The total minute ventilation necessary to achieve normocapnia decreased with increasing weight, while the alveolar minute ventilation remained constant.

BACKGROUND: The severity of SARS-CoV-2-related diseases in children remains unclear. This study aimed to describe the incidence of French pediatric intensive care units (PICUs) admissions with acute COVID-19, incidental positive SARS-CoV-2 test result, and multisystem inflammatory syndrome in children (MIS-C) during the delta and omicron variant periods. METHODS: This study used the French PICU registry to obtain data on all patients admitted to 41 French PICUs diagnosed with acute COVID-19, incidental positive SARS-CoV-2 test result, or MIS-C between August 30, 2021 and April 20, 2022. Data regarding the total number of positive SARS-CoV-2 polymerase chain reaction results according to the type of variants were obtained from the French National Public Health Agency. RESULTS: Of 745 children, 244 (32.8%) were admitted for acute COVID-19, 246 (33.0%) for incidental positive SARS-CoV-2 test results, and 255 (34.2%) for MIS-C. The incidence of each group was higher with delta than with omicron. The incidence rate ratios with the delta variant were 7.47 (95% CI, 4.22-13.26) for acute COVID-19, 4·78 (95% CI, 2.30-9.94) for incidental positive SARS-CoV-2 test results, and 10.46 (95% CI, 5.98-18.31) for MIS-C compared to the omicron variant. The median age was 66 (7.7-126.8) months; 314 (42%) patients had comorbidities. Patients with acute COVID-19 and incidental positive SARS-CoV-2 test results had similar proportions of comorbidities. No patient with MIS-C died, whereas the mortality rates in the acute COVID-19 and incidental positive SARS-CoV-2 test results groups were 6.8% and 3.8%, respectively. CONCLUSIONS: The incidence of acute COVID-19, incidental positive SARS-CoV-2 test results, and MIS-C admitted to the PICU were significantly higher with the delta variant than with the omicron variant.

BACKGROUND: Neurally adjusted ventilatory assist (NAVA) is a ventilatory mode that delivers synchronized ventilation, proportional to the electrical activity of the diaphragm (EAdi). Although it has been proposed in infants with a congenital diaphragmatic hernia (CDH), the diaphragmatic defect and the surgical repair could alter the physiology of the diaphragm. AIM: To evaluate, in a pilot study, the relationship between the respiratory drive (EAdi) and the respiratory effort in neonates with CDH during the postsurgical period under either NAVA ventilation or conventional ventilation (CV). METHODS: This prospective physiological study included eight neonates admitted to a neonatal intensive care unit with a diagnosis of CDH. EAdi, esophageal, gastric, and transdiaphragmatic pressure, as well as clinical parameters, were recorded during NAVA and CV (synchronized intermittent mandatory pressure ventilation) in the postsurgical period. RESULTS: EAdi was detectable and there was a correlation between the ΔEAdi (maximal - minimal values) and the transdiaphragmatic pressure (r = 0.26, 95% confidence interval [CI] [0.222; 0.299]). There was no significant difference in terms of clinical or physiological parameters during NAVA compared to CV, including work of breathing. CONCLUSION: Respiratory drive and effort were correlated in infants with CDH and therefore NAVA is a suitable proportional mode in this population. EAdi can also be used to monitor the diaphragm for individualized support.

OBJECTIVES: We sought to update our 2015 work in the Second Pediatric Acute Lung Injury Consensus Conference (PALICC-2) guidelines for the diagnosis and management of pediatric acute respiratory distress syndrome (PARDS), considering new evidence and topic areas that were not previously addressed. DESIGN: International consensus conference series involving 52 multidisciplinary international content experts in PARDS and four methodology experts from 15 countries, using consensus conference methodology, and implementation science. SETTING: Not applicable. PATIENTS: Patients with or at risk for PARDS. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Eleven subgroups conducted systematic or scoping reviews addressing 11 topic areas: 1) definition, incidence, and epidemiology; 2) pathobiology, severity, and risk stratification; 3) ventilatory support; 4) pulmonary-specific ancillary treatment; 5) nonpulmonary treatment; 6) monitoring; 7) noninvasive respiratory support; 8) extracorporeal support; 9) morbidity and long-term outcomes; 10) clinical informatics and data science; and 11) resource-limited settings. The search included MEDLINE, EMBASE, and CINAHL Complete (EBSCOhost) and was updated in March 2022. Grading of Recommendations, Assessment, Development, and Evaluation methodology was used to summarize evidence and develop the recommendations, which were discussed and voted on by all PALICC-2 experts. There were 146 recommendations and statements, including: 34 recommendations for clinical practice; 112 consensus-based statements with 18 on PARDS definition, 55 on good practice, seven on policy, and 32 on research. All recommendations and statements had agreement greater than 80%. CONCLUSIONS: PALICC-2 recommendations and consensus-based statements should facilitate the implementation and adherence to the best clinical practice in patients with PARDS. These results will also inform the development of future programs of research that are crucially needed to provide stronger evidence to guide the pediatric critical care teams managing these patients.

OBJECTIVES: Monitoring is essential to assess changes in the lung condition, to identify heart-lung interactions, and to personalize and improve respiratory support and adjuvant therapies in pediatric acute respiratory distress syndrome (PARDS). The objective of this article is to report the rationale of the revised recommendations/statements on monitoring from the Second Pediatric Acute Lung Injury Consensus Conference (PALICC-2). DATA SOURCES: MEDLINE (Ovid), Embase (Elsevier), and CINAHL Complete (EBSCOhost). STUDY SELECTION: We included studies focused on respiratory or cardiovascular monitoring of children less than 18 years old with a diagnosis of PARDS. We excluded studies focused on neonates. DATA EXTRACTION: Title/abstract review, full-text review, and data extraction using a standardized data collection form. DATA SYNTHESIS: The Grading of Recommendations Assessment, Development and Evaluation approach was used to identify and summarize evidence and develop recommendations. We identified 342 studies for full-text review. Seventeen good practice statements were generated related to respiratory and cardiovascular monitoring. Four research statements were generated related to respiratory mechanics and imaging monitoring, hemodynamics monitoring, and extubation readiness monitoring. CONCLUSIONS: PALICC-2 monitoring good practice and research statements were developed to improve the care of patients with PARDS and were based on new knowledge generated in recent years in patients with PARDS, specifically in topics of general monitoring, respiratory system mechanics, gas exchange, weaning considerations, lung imaging, and hemodynamic monitoring.

PURPOSE: We present guidelines for the management of infants under 12 months of age with severe bronchiolitis with the aim of creating a series of pragmatic recommendations for a patient subgroup that is poorly individualized in national and international guidelines. METHODS: Twenty-five French-speaking experts, all members of the Groupe Francophone de Réanimation et Urgence Pédiatriques (French-speaking group of paediatric intensive and emergency care; GFRUP) (Algeria, Belgium, Canada, France, Switzerland), collaborated from 2021 to 2022 through teleconferences and face-to-face meetings. The guidelines cover five areas: (1) criteria for admission to a pediatric critical care unit, (2) environment and monitoring, (3) feeding and hydration, (4) ventilatory support and (5) adjuvant therapies. The questions were written in the Patient-Intervention-Comparison-Outcome (PICO) format. An extensive Anglophone and Francophone literature search indexed in the MEDLINE database via PubMed, Web of Science, Cochrane and Embase was performed using pre-established keywords. The texts were analyzed and classified according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. When this method did not apply, an expert opinion was given. Each of these recommendations was voted on by all the experts according to the Delphi methodology. RESULTS: This group proposes 40 recommendations. The GRADE methodology could be applied for 17 of them (3 strong, 14 conditional) and an expert opinion was given for the remaining 23. All received strong approval during the first round of voting. CONCLUSION: These guidelines cover the different aspects in the management of severe bronchiolitis in infants admitted to pediatric critical care units. Compared to the different ways to manage patients with severe bronchiolitis described in the literature, our original work proposes an overall less invasive approach in terms of monitoring and treatment.

Background and Aim: The SplashGuard CG (SG) is a barrier enclosure developed to protect healthcare workers from SARS-CoV-2 transmission during aerosol-generating procedures. Our objective was to evaluate the protection provided by the SG against aerosolized particles (AP), using a pediatric simulation model of spontaneous ventilation (SV) and noninvasive ventilation (NIV). Methods: An aerosol generator was connected to the airways of a pediatric high-fidelity manikin with a breathing simulator. AP concentrations were measured both in SV and NIV in the following conditions: with and without SG, inside and outside the SG, with and without suction applied to the device. Results: In the SV simulated setting, AP peaks were lower with SG: 0.1 × 105 particles/L compared to without: 1.6 × 105, only when the ports were closed and suction applied. In the NIV simulated setting, AP peaks outside the SG were lower than without SG (20.5 × 105 particles/L), whatever the situation, without suction (14.4 × 105particles/L), with suction and ports open or closed: 10.3 and 0.7 × 105 particles/L. In SV and NIV simulated settings, the AP peaks measured within the SG were much higher than the AP peaks measured without SG, even when suction was applied to the device. Conclusions: The SG seems to decrease peak AP exposure in the 2 ventilation contexts, but only with closed port and suction in SV. However, high concentrations of AP remain inside even with suction and SG should be used cautiously.

INTRODUCTION: Recent studies have shown the prognostic value of capillary refill time (CRT) and suggested that resuscitation management guided by CRT may reduce morbidity and mortality in patients with septic shock. However, little is known about the current use of CRT in routine clinical practice. This study aimed to assess the modalities of CRT use among French adult and pediatric intensivists. METHODS: A cross-sectional survey exploring CRT practices in acute circulatory failure was performed. The targeted population was French adult and pediatric intensivists (SFAR and GFRUP networks). An individual invitation letter including a survey of 32 questions was emailed twice. Descriptive and analytical statistics were performed. RESULTS: Among the 6071 physicians who received the letter, 418 (7%) completed the survey. Among all respondents, 82% reported using CRT in routine clinical practice, mainly to diagnose acute circulatory failure, but 45% did not think CRT had any prognostic value. Perfusion goal-directed therapy based on CRT was viewed as likely to improve patient outcome by 37% of respondents. The measurement of CRT was not standardized as the use of a chronometer was rare (3%) and the average of multiple measurements rarely performed (46%). Compared to adult intensivists, pediatric intensivists used CRT more frequently (99% versus 76%) and were more confident in its diagnostic value and its ability to guide treatment. CONCLUSION: CRT measurement is widely used by intensivists in patients with acute circulatory failure but most often in a non-standardized way. This may lead to a misunderstanding of CRT reliability and clinical usefulness.

Introduction: Early enteral nutrition is recommended for critically ill children, potentially exposing those who are undernourished to the risk of refeeding syndrome. However, data on its incidence is lacking, and the heterogeneity of diagnostic criteria and frequent electrolyte disorders in this population make its diagnosis complex. In 2020, the American Society for Parenteral and Enteral Nutrition (ASPEN) developed consensus recommendations for identifying patients at risk and with refeeding syndrome. These state that undernourished children are considered at risk of refeeding syndrome; those who develop one significant electrolyte disorder (decrease ≥ 10% in phosphorus, potassium, and/or magnesium) within the first five days of nutritional support, combined with a significant increase in energy intake, are considered to have refeeding syndrome. The aim of this study was to determine the incidence of refeeding syndrome according to the ASPEN definition in critically ill children on nutritional support. Materials and Methods: A secondary analysis of two prospective cohorts conducted in a tertiary pediatric intensive care unit in France was undertaken, and additional data were retrospectively collected. Children included were those (0-18 years) admitted to the pediatric intensive care unit with a minimum of one phosphorus, potassium, and/or magnesium assay and who received exclusive or supplemental nutritional support. Undernourished children (body mass index z-score < -2 standard deviations) were considered at risk of refeeding syndrome. The ASPEN critiera were used to identify those with probable refeeding syndrome. Results: A total of 1,261 children were included in the study, with 199 children (15.8%) classified as undernourished, who were at risk of refeeding syndrome. Of these, 93 children were identified as having probable refeeding syndrome, giving an overall incidence of 7.4%. The incidence rate among at-risk children was 46.7%. Most patients (58.1%) were classified as having severe refeeding syndrome. Conclusion: Refeeding syndrome remains difficult to diagnose in critically ill children, due to frequent confounding factors impacting electrolyte plasma levels. These findings suggest that refeeding syndrome incidence may be high in undernourished children, and that refeeding syndromes can be severe. Further prospective studies using the ASPEN definition and risk criteria are required.
RESUMEN
Introduction: Cumulative energy/protein deficit is associated with impaired outcomes in pediatric intensive care Units (PICU). Enteral nutrition is the preferred mode, but its delivery may be compromised by periods of feeding interruptions around procedures, with peri-extubation fasting the most common procedure. Currently, there is no evidence to guide the duration of the peri-extubation fasting in PICU. Therefore, we aimed to explore current PICU fasting practices around the time of extubation and the rationales supporting them. Materials and Methods: A cross sectional electronic survey was disseminated via the European Pediatric Intensive Care Society (ESPNIC) membership. Experienced senior nurses, dieticians or doctors were invited to complete the survey on behalf of their unit, and to describe their practice on PICU fasting prior to and after extubation. Results: We received responses from 122 PICUs internationally, mostly from Europe. The survey confirmed that fasting practices are often extrapolated from guidelines for fasting prior to elective anesthesia. However, there were striking differences in the duration of fasting times, with some units not fasting at all (in patients considered to be low risk), while others withheld feeding for all patients. Fasting following extubation also showed large variations in practice: 46 (38%) and 26 (21%) of PICUs withheld oral and gastric/jejunal nutrition more than 5 h, respectively, and 45 (37%) started oral feeding based on child demand. The risk of vomiting/aspiration and reducing nutritional deficit were the main reasons for fasting children [78 (64%)] or reducing fasting times [57 (47%)] respectively. Discussion: This variability in practices suggests that shorter fasting times might be safe. Shortening the duration of unnecessary fasting, as well as accelerating the extubation process could potentially be achieved by using other methods of assessing gastric emptiness, such as gastric point of care ultrasonography (POCUS). Yet only half of the units were aware of this technique, and very few used it.
RESUMEN
OBJECTIVES: To describe mechanical ventilation management and factors associated with nonadherence to lung-protective ventilation principles in pediatric acute respiratory distress syndrome. DESIGN: A planned ancillary study to a prospective international observational study. Mechanical ventilation management (every 6 hr measurements) during pediatric acute respiratory distress syndrome days 0-3 was described and compared with Pediatric Acute Lung Injury Consensus Conference tidal volume recommendations (< 7 mL/kg in children with impaired respiratory system compliance, < 9 mL/kg in all other children) and the Acute Respiratory Distress Syndrome Network lower positive end-expiratory pressure/higher Fio2 grid recommendations. SETTING: Seventy-one international PICUs. PATIENTS: Children with pediatric acute respiratory distress syndrome. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Analyses included 422 children. On pediatric acute respiratory distress syndrome day 0, median tidal volume was 7.6 mL/kg (interquartile range, 6.3-8.9 mL/kg) and did not differ by pediatric acute respiratory distress syndrome severity. Plateau pressure was not recorded in 97% of measurements. Using delta pressure (peak inspiratory pressure - positive end-expiratory pressure), median tidal volume increased over quartiles of median delta pressure (p = 0.007). Median delta pressure was greater than or equal to 18 cm H2O for all pediatric acute respiratory distress syndrome severity levels. In severe pediatric acute respiratory distress syndrome, tidal volume was greater than or equal to 7 mL/kg 62% of the time, and positive end-expiratory pressure was lower than recommended by the positive end-expiratory pressure/Fio2 grid 70% of the time. In multivariable analysis, tidal volume nonadherence was more common with severe pediatric acute respiratory distress syndrome, fewer PICU admissions/yr, non-European PICUs, higher delta pressure, corticosteroid use, and pressure control mode. Adherence was associated with underweight stature and cuffed endotracheal tubes. In multivariable analysis, positive end-expiratory pressure/Fio2 grid nonadherence was more common with higher pediatric acute respiratory distress syndrome severity, ventilator decisions made primarily by the attending physician, pre-ICU cardiopulmonary resuscitation, underweight stature, and age less than 2 years. Adherence was associated with respiratory therapist involvement in ventilator management and longer time from pediatric acute respiratory distress syndrome diagnosis. Higher nonadherence to tidal volume and positive end-expiratory pressure recommendations were independently associated with higher mortality and longer duration of ventilation after adjustment for confounding variables. In stratified analyses, these associations were primarily influenced by children with severe pediatric acute respiratory distress syndrome. CONCLUSIONS: Nonadherence to lung-protective ventilation principles is common in pediatric acute respiratory distress syndrome and may impact outcome. Modifiable factors exist that may improve adherence.

Neurological morbidity is a growing concern in children with severe bronchiolitis. The aim of the study was to evaluate the frequency of occurrence and the factors associated with seizures in very young infants < 3 months of age, admitted to a pediatric intensive care unit (PICU) for severe bronchiolitis. We performed a single center retrospective cohort study evaluating occurrence of seizures in infants admitted to the PICU between 2010 and 2018 for severe bronchiolitis. We described characteristics of the patients, laboratory test, brain imaging, and electroencephalogram results, as well as the treatment used. We conducted a multivariable logistic regression to identify factors associated with the occurrence of seizures. A p value < 0.05 was considered significant. A total of 805 patients were included in the study; 722 (89.6%) were mechanically ventilated. Twenty-six infants (3.2%, 95% confidence interval, 95% CI [2.1%; 4.7%]) had seizures shortly prior to admission or during PICU stay. In the multivariable analysis, hyponatremia (odds ratio, OR: 4.6, 95%CI [1.86; 11.43], p = 0.001) and invasive ventilation (OR: 2.6, 95% CI [1.14; 5.9], p < 0.001) were associated with an increased likelihood of seizures occurrence.Conclusion: Seizures occur in at least 3% of very young infants with severe bronchiolitis, and the characteristics of these are different to those experienced by older infants, but they shared the same risk factors (hyponatremia and mechanical ventilation). This highlights the extrapulmonary morbidity associated with bronchiolitis in this population. What is Known: ⢠Bronchiolitis is the leading cause of pediatric intensive care admission and use of mechanical ventilation in infants. ⢠Neurological morbidities have to be investigated in this population at risk of neurological complications. What is New: ⢠Seizure is a complication in at least 3% of very young infants with severe bronchiolitis. ⢠Seizure characteristics are different, but the main risk factors are the same than in older infants (hyponatremia and mechanical ventilation).

BACKGROUND: Many critically ill children can be fed orally at some point during their paediatric intensive care (PICU) stay, but reduced appetite and other factors may impact their intake. At home, oral feeding is usually delivered by parents, so involving parents more actively during mealtimes in the PICU may contribute to improved patient/family satisfaction. AIM: To assess the impact of a new "room service" initiative involving parents on mealtime quality and on both family and health care professional (HCP) satisfaction. METHODS: A prospective, single-centre, before-and-after intervention study was designed as part of a PICU quality-of-care improvement programme in 2013 to 2016. Two questionnaires assessing oral nutrition practices and family/HCP overall satisfaction were disseminated among the parents of critically ill children capable of oral feeding during their PICU admission and among the whole PICU HCP team (nurses, nurse assistants, and medical doctors). Categorical variables were compared using the chi-square test, and Likert scales were compared between groups with the Mann-Whitney-Wilcoxon test. RESULTS: the pre-intervention surveys were completed by 97 of 130 (75%) HCPs and 52 families and the post-intervention surveys by 74 of 130 (57%) HCPs and 54 families. After the intervention, a marked improvement was observed in the overall quality of meal service rating by both HCPs and families (medians and IQR: 5 (5-7) to 7 (7, 8) and 6 (6-8) to 8 (7-9), respectively; P < .01) and also in parents' involvement; in children's, families', and HCP satisfaction; in meal-dedicated facilities and equipment; and in perception that oral nutrition is an important aspect of PICU care. CONCLUSIONS: Implementation of an improved "room service" initiative in the PICU was feasible and improved the perceived quality of care and satisfaction around oral feeding. This family-centred care initiative can be integrated in an overall quality improvement strategy.
