ABSTRACT

OBJECTIVES: To describe the different pathways of management of intussusception (IS) in infants and children in metropolitan France and to identify paediatric emergency centres that might constitute a surveillance network for IS.

MATERIAL AND METHODS: A questionnaire was sent to 273 paediatric emergency centres distributed across France in 2005. Modalities of diagnosis and treatment of IS had to be precised.

RESULTS: One hundred and sixty-seven centres (61.2%) responded. The response was given by 131 paediatricians (78.4%) and 36 surgeons (21.6%) working in 38 universitary hospitals (22.7%) and 129 general hospitals (77.2%). The mean number of IS treated in each centre in 2004 was 11+/-13.5 (extr. 0 to 70; median 6). Diagnosis of IS required a collaboration between medical and surgical teams in 51.5% of the centres, but in 40.1% the sole medical team was in charge of the diagnosis. Ultrasonography is used for diagnosis by 98.8% of the centres. Reduction with hydrostatic enema and eventually surgery was performed in the same hospital in 44.3%. Other centres systematically or frequently transferred the patients for reduction, mostly towards universitary hospitals (90%).

CONCLUSION: The procedures of IS diagnosis are the same everywhere in France but the pathways of therapeutic management do vary, depending on the availability of surgeons and anaesthetists trained in paediatrics on each site. These disparities will probably change with the implementation of the new plan for sanitary organization in children and adolescents in France. Labellized paediatric emergency centres will gather more surgical patients and could eventually constitute an effective surveillance network for IS.

ABSTRACT

INTRODUCTION: High-flow nasal cannula (HFNC) is commonly used as first step respiratory support in infants with moderate-to-severe acute viral bronchiolitis (AVB). This device, however, fails to effectively manage respiratory distress in about a third of patients, and data are limited on determinants of patient response. The respiratory rate-oxygenation (ROX) index is a relevant tool to predict the risk for HFNC failure in adult patients with lower respiratory tract infections. The primary objective of this study was to assess the relationship between ROX indexes collected before and 1 h after HFNC initiation, and HFNC failure occurring in the following 48 h in infants with AVB.

METHOD: This is an ancillary study to the multicenter randomized controlled trial TRAMONTANE 2, that included 286 infants of less than 6 months with moderate-to-severe AVB. Collection of physiological variables at baseline (H0), and 1 h after HFNC (H1), included heart rate (HR), respiratory rate (RR), fraction of inspired oxygen (FiO₂), respiratory distress score (modified Wood's Clinical Asthma Score [mWCAS]), and pain and discomfort scale (EDIN). ROX and ROX-HR were calculated as $\frac{\left(\frac{{\mathrm{SpO}}_2}{{\mathrm{FiO}}_2}\right)}{\mathrm{RR}}$ and $100\times \frac{\mathrm{ROX}}{\mathrm{HR}}$ , respectively. Predefined HFNC failure criteria included increase in respiratory distress score or RR, increase in discomfort, and severe apnea episodes. The accuracies of ROX, ROX-HR indexes and clinical variable to predict HFNC failure were assessed using receiver operating curve analysis. We analyzed predictive factors of HFNC failure using multivariate logistic regressions.

RESULT: HFNC failure occurred in 111 of 286 (39%) infants, and for 56 (50% of the failure) of them within the first 6 h. The area under the curve of ROX indexes at H0 and H1 were, respectively, 0.56 (95% confidence interval [CI] 0.48-0.63, p = 0.14), 0.56 (95% CI 0.49-0.64, p = 0.09). ROX-HR performances were better but remained poorly discriminant. HFNC failure was associated with higher mWCAS score at H1 (p < 0.01) and lower decrease in EDIN scale during the first hour of HFNC delivery (p = 0.02). In the multivariate analyses, age and mWCAS score were were found to be independent factors associated with HFNC failure at H0. At H1, weight and mWCAS were associated factors.

CONCLUSION: In this study, neither ROX index, nor physiological variables usually collected in infants with AVB had early discriminatory capacity to predict HFNC failure.

ABSTRACT

PURPOSE: High-flow nasal cannula (HFNC) therapy is increasingly proposed as first-line respiratory support for infants with acute viral bronchiolitis (AVB). Most teams use 2 L/kg/min, but no study compared different flow rates in this setting. We hypothesized that 3 L/kg/min would be more efficient for the initial management of these patients.

METHODS: A randomized controlled trial was performed in 16 pediatric intensive care units (PICUs) to compare these two flow rates in infants up to 6 months old with moderate to severe AVB and treated with HFNC. The primary endpoint was the percentage of failure within 48 h of randomization, using prespecified criteria of worsening respiratory distress and discomfort.

RESULTS: From November 2016 to March 2017, 142 infants were allocated to the 2-L/kg/min (2L) flow rate and 144 to the 3-L/kg/min (3L) flow rate. Failure rate was comparable between groups: 38.7% (2L) vs. 38.9% (3L; p = 0.98). Worsening respiratory distress was the most common cause of failure in both groups: 49% (2L) vs. 39% (3L; p = 0.45). In the 3L group, discomfort was more frequent (43% vs. 16%, p = 0.002) and PICU stays were longer (6.4 vs. 5.3 days, p = 0.048). The intubation rates [2.8% (2L) vs. 6.9% (3L), p = 0.17] and durations of invasive [0.2 (2L) vs. 0.5 (3L) days, p = 0.10] and noninvasive [1.4 (2L) vs. 1.6 (3L) days, p = 0.97] ventilation were comparable. No patient had air leak syndrome or died.

CONCLUSION: In young infants with AVB supported with HFNC, 3 L/kg/min did not reduce the risk of failure compared with 2 L/kg/min. This clinical trial was recorded on the National Library of Medicine registry (NCT02824744).

ABSTRACT

The latest French Guidelines for the management in the first 24hours of patients with severe traumatic brain injury (TBI) were published in 1998. Due to recent changes (intracerebral monitoring, cerebral perfusion pressure management, treatment of raised intracranial pressure), an update was required. Our objective has been to specify the significant developments since 1998. These guidelines were conducted by a group of experts for the French Society of Anesthesia and Intensive Care Medicine (Société francaise d'anesthésie et de réanimation [SFAR]) in partnership with the Association de neuro-anesthésie-réanimation de langue française (ANARLF), The French Society of Emergency Medicine (Société française de médecine d'urgence (SFMU), the Société française de neurochirurgie (SFN), the Groupe francophone de réanimation et d'urgences pédiatriques (GFRUP) and the Association des anesthésistes-réanimateurs pédiatriques d'expression française (ADARPEF). The method used to elaborate these guidelines was the Grade^® method. After two Delphi rounds, 32 recommendations were formally developed by the experts focusing on the evaluation the initial severity of traumatic brain injury, the modalities of prehospital management, imaging strategies, indications for neurosurgical interventions, sedation and analgesia, indications and modalities of cerebral monitoring, medical management of raised intracranial pressure, management of multiple trauma with severe traumatic brain injury, detection and prevention of post-traumatic epilepsia, biological homeostasis (osmolarity, glycaemia, adrenal axis) and paediatric specificities.

ABSTRACT

The fact that some children may survive despite a decision of limitation of treatments (DLT) is taken in Paediatric Intensive Care Unit (PICU) is a recent data. Although the French-speaking Group of Paediatric Intensive and Emergency Care (GFRUP) has published guidelines for limitation of treatments in PICU, outcome of these surviving children has not yet been studied.

PURPOSES: To evaluate transmission of data concerning DLT in PICU toward teams in charge of children after the PICU stay and to evaluate perennility of these decisions.

METHOD: Cohort study in children for whom DLT was discussed and who were discharged from PICU between 2002 and 2006. The study included an analysis of the medical files and discussions with the physicians in charge of children at the time of the study, including their responses to standardised scenarios concerning the outcome of their patients.

RESULTS: Among the 96 children for whom DLT was discussed in PICU, 37 were discharged toward another unit. Only 1 discharge letter mentioned the DLT. At the time of the study, the Pediatric Overall Performance Category (POPC) score had increased in 16 children and was stable in 12. All the 6 children with a worsening POPC score died, without PICU readmission. The physicians in charge of children after the PICU stay did not remember any DLT. For 18 children (including 8 with previous DLT) PICU readmission would be proposed in case of life-threatening event. Their median POPC score at the time of study was lower than that of other children (3 versus 4; p=0.001).

CONCLUSION: This study shows a lack of DLT data transmission, which is in contradiction with the GFRUP's guidelines. Correction of this lack is essential to improve cooperation between units in charge of these children.

ABSTRACT

BACKGROUND: Patients under extra-corporeal membrane oxygenation (ECMO) are at high risk of developing acute kidney injury and renal replacement therapy (RRT) is frequently needed. The aim of this study was to explore RRT use in ECMO patients, as no recommendations exist in this setting.

METHODS: An online questionnaire about RRT management in ECMO patients was sent to the members of the ARCOTHOVA (Anesthésie-Réanimation Coeur-Thorax-Vaisseaux) association and to the GFRUP (Groupe Francophone de Réanimation et Urgences Pédiatriques).

RESULTS: Ninety intensivists from adult ICU and twenty from paediatric ICU responded to the questionnaire. RRT use was common as 67% respondents reported that more than 25% of their ECMO patients needed RRT. RRT indications were similar between centres, with persistent anuria (83%), metabolic acidosis (80%), fluid overload (78%) and hyperkalaemia (80%) being the more prevalent. Continuous renal replacement therapy was the preferred technique (97%). Continuous veno-venous haemofiltration was predominant (64%) over continuous veno-venous haemodiafiltration (21%). Unfractionated heparin was employed as first line choice anticoagulation in 61% and regional citrate anticoagulation in 16%. Integration of RRT device directly into the ECMO circuit was the preferred configuration (40%) while parallel systems with separate catheter were used in 30%. When the integrated approach was chosen, RRT device was most frequently connected with inlet and outlet lines after the ECMO pump (58%) and pressure alarms were encountered for 60% of participants.

CONCLUSIONS: Our results highlight the high variability of practice between centres. They suggest the need to compare the integrated and parallel configurations of combining RRT and ECMO.

ABSTRACT

OBJECTIVE: Multiple organ dysfunction syndrome is the main cause of death in adult ICUs and in PICUs. The PEdiatric Logistic Organ Dysfunction score developed in 1999 was primarily designed to describe the severity of organ dysfunction. This study was undertaken to update and improve the PEdiatric Logistic Organ Dysfunction score, using a larger and more recent dataset.

DESIGN: Prospective multicenter cohort study.

SETTING: Nine multidisciplinary, tertiary-care PICUs of university-affiliated hospitals in France and Belgium.

PATIENTS: All consecutive children admitted to these PICUs (June 2006-October 2007).

INTERVENTION: None.

MEASUREMENTS AND MAIN RESULTS: We collected data on variables considered for the PEdiatric Logistic Organ Dysfunction-2 score during PICU stay up to eight time points: days 1, 2, 5, 8, 12, 16, and 18, plus PICU discharge. For each variable considered for the PEdiatric Logistic Organ Dysfunction-2 score, the most abnormal value observed during time points was collected. The outcome was vital status at PICU discharge. Identification of the best variable cutoffs was performed using bivariate analyses. The PEdiatric Logistic Organ Dysfunction-2 score was developed by multivariable logistic regressions and bootstrap process. We used areas under the receiver-operating characteristic curve to evaluate discrimination and Hosmer-Lemeshow goodness-of-fit tests to evaluate calibration. We enrolled 3,671 consecutive patients (median age, 15.5 mo; interquartile range, 2.2-70.7). Mortality rate was 6.0% (222 deaths). The PEdiatric Logistic Organ Dysfunction-2 score includes ten variables corresponding to five organ dysfunctions. Discrimination (areas under the receiver-operating characteristic curve = 0.934) and calibration (chi-square test for goodness-of-fit = 9.31, p = 0.317) of the PEdiatric Logistic Organ Dysfunction-2 score were good.

CONCLUSION: We developed and validated the PEdiatric Logistic Organ Dysfunction-2 score, which allows assessment of the severity of cases of multiple organ dysfunction syndrome in the PICU with a continuous scale. The PEdiatric Logistic Organ Dysfunction-2 score now includes mean arterial pressure and lactatemia in the cardiovascular dysfunction and does not include hepatic dysfunction. The score will be in the public domain, which means that it can be freely used in clinical trials.

ABSTRACT

Over the recent period, the use of induced hypothermia has gained an increasing interest for critically ill patients, in particular in brain-injured patients. The term "targeted temperature management" (TTM) has now emerged as the most appropriate when referring to interventions used to reach and maintain a specific level temperature for each individual. TTM may be used to prevent fever, to maintain normothermia, or to lower core temperature. This treatment is widely used in intensive care units, mostly as a primary neuroprotective method. Indications are, however, associated with variable levels of evidence based on inhomogeneous or even contradictory literature. Our aim was to conduct a systematic analysis of the published data in order to provide guidelines. We present herein recommendations for the use of TTM in adult and paediatric critically ill patients developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. These guidelines were conducted by a group of experts from the French Intensive Care Society (Société de Réanimation de Langue Française [SRLF]) and the French Society of Anesthesia and Intensive Care Medicine (Société Francaise d'Anesthésie Réanimation [SFAR]) with the participation of the French Emergency Medicine Association (Société Française de Médecine d'Urgence [SFMU]), the French Group for Pediatric Intensive Care and Emergencies (Groupe Francophone de Réanimation et Urgences Pédiatriques [GFRUP]), the French National Association of Neuro-Anesthesiology and Critical Care (Association Nationale de Neuro-Anesthésie Réanimation Française [ANARLF]), and the French Neurovascular Society (Société Française Neurovasculaire [SFNV]). Fifteen experts and two coordinators agreed to consider questions concerning TTM and its practical implementation in five clinical situations: cardiac arrest, traumatic brain injury, stroke, other brain injuries, and shock. This resulted in 30 recommendations: 3 recommendations were strong (Grade 1), 13 were weak (Grade 2), and 14 were experts' opinions. After two rounds of rating and various amendments, a strong agreement from voting participants was obtained for all 30 (100%) recommendations, which are exposed in the present article.

ABSTRACT

BACKGROUND: Data about the risk of anaphylaxis recurrence in children are lacking. We assessed anaphylaxis recurrence and medical follow-up in a cohort of children previously hospitalized in a French pediatric intensive care unit (PICU) for anaphylaxis.

METHODS: We conducted a telephone survey of 166 children (≤18 years) hospitalized from 2003 to 2013.

RESULTS: In all, 106 (64%) completed the survey (boys, 59%; mean age [SD]: 15.3 years [5.5]). The main index triggers were drugs (45%) and foods (37%). The mean duration follow-up was of 7.7 years (SD: 2.4). Thirty-eight (36%) children experienced 399 new allergic reactions during a follow-up period of 282 patient-years (incidence rate: 1.4/100 patients/y; 95% CI: 0.64-2.04). Twelve children experienced 19 anaphylaxis reactions including five requiring PICU admission (anaphylaxis recurrence rate: 0.20/100 patients/y; 95% CI non-calculable). Food was the trigger for 79% of recurrent reactions and drugs for 8%. The food trigger was previously known in 83%, the same as the index trigger in 69%. Overall, 1.5% of the recurrent reactions were treated with adrenaline injection and 8% an emergency hospital admission. Patients with recurrence had more likely a history of food allergy (P < 10^-4 ), asthma (P < 0.005), atopic dermatitis (P < 0.05) than those without. 31% of the 50 children with food allergy did not see an allergist, 23% had no adrenaline auto-injector, and 26% lacked a school individual healthcare plan.

CONCLUSIONS: Following a PICU admission for anaphylaxis, recurrence is high in children with food allergy compared with drug allergy. Allergic comorbidities increase the risk. Medical follow-up has to be improved for these at-risk children.
