    ABSTRACT: The aim of this investigation was to conduct a comprehensive examination of communication between parents and health care professionals (HCPs) in the pediatric intensive care unit (PICU). A secondary analysis was performed on data from 3 previous qualitative studies, which included 30 physicians, 37 nurses, and 38 parents in France and Quebec (Canada). All three studies examined a mix of cases where children either survived or died. All data referring to communication between parents (and patients when applicable) and HCPs were examined to identity themes that related to communication. Thematic categories for parents and HCPs were developed. Three interrelated dimensions of communication were identified: (1) informational communication, (2) relational communication, and (3) communication and parental coping. Specific themes were identified for each of these 3 dimensions in relation to parental concerns as well as HCP concerns. This investigation builds on prior research by advancing a comprehensive analysis of PICU communication that includes (a) cases where life-sustaining treatments were withdrawn or withheld as well as cases where they were maintained, (b) data from HCPs as well as parents, and (c) investigations conducted in 4 different sites. An evidence-informed conceptual framework is proposed for PICU communication between parents and HCPs. We also outline priorities for the development of practice, education, and research.

    ABSTRACT: Background. About 10% of pediatric patients with invasive pneumococcal disease (IPD) die from the disease. Some primary immunodeficiencies (PIDs) are known to confer predisposition to IPD. However, a systematic search for these PIDs has never been carried out in children presenting with IPD. Methods. We prospectively collected pediatric cases of IPD requiring hospitalization, between 2005 and 2011, in 28 pediatric wards throughout France. IPD was defined as a positive pneumococcal culture, PCR result and/or soluble antigen detection at a normally sterile site. The immunological assessment included abdominal ultrasound, whole-blood counts and smears, determinations of plasma Ig and complement levels, and the evaluation of pro-inflammatory cytokines. Results. We included a total of 163 children with IPD (M/F sex ratio: 1.3, median age: 13 months). Seventeen children had recurrent IPD. Meningitis was the most frequent type of infection (87%), others were pleuropneumonitis, isolated bloodstream infection, osteomyelitis, endocarditis and mastoiditis. One patient with recurrent meningitis had a congenital cerebrospinal fluid fistula. The results of immunological explorations were abnormal in 26 children (16%) and a PID was identified in 17 patients (10%), including one case of MyD88 deficiency, three of complement fraction C2 or C3 deficiencies, one of isolated congenital asplenia and two of Bruton's agammaglobulinemia. The proportion of PIDs was much higher in children older than two years than in younger children (26% vs 2%, p<0.001). Conclusions. Children with IPD should undergo immunological investigations, particularly those older than two years, as PIDs may be discovered in up to 26% of cases.

    ABSTRACT: Background: Data on the effects of general anesthesia on the fetal and neonatal brain are limited. Animal studies demonstrated that anesthetic agents leave their consequences in the form of learning and memory deficits. The effects of propofol on the fetal neurodevelopment are not clear yet. Materials and Methods: This is a telephone-based questionnaire survey that addressed the effect of general anesthesia by propofol during cesarean section at term with no perinatal complications on the psychosocial behavior of children at 8-10 years of age compared with children having same characteristics except for delivery under neuraxial anesthesia using the Pediatric Symptom Checklist as a score. Results: A total of 187 children were born at term between January 1, 2002 and December 31, 2004 with no perinatal distress under induction of general anesthesia by propofol. 66 children (35.3%) were lost to follow-up and parents of two children (1.1%) refused to participate. A total of 189 children were included in the study: 119 were born by cesarean section under general anesthesia and 70 were born by cesarean section under neuraxial block. The incidence of psychosocial behavior impairment at 8-10 years of age was not found to be affected by the mode of anesthesia during delivery by cesarean section nor by neonatal nor parental characteristics. Conclusion: Exposure to propofol as an induction agent for general anesthesia or cesarean section does not seem to increase the psychosocial behavior disorder development risk at 8-10 years of age.

    ABSTRACT: La formation en réanimation pédiatrique relève d’un véritable défi en raison de l’augmentation croissante des connaissances et des compétences, de la relative rareté des situations critiques et de la diminution de présence des étudiants auprès des patients. La simulation est une des méthodes pédagogiques pouvant améliorer notablement cette formation. Elle est par ailleurs éthiquement nécessaire, tout particulièrement pour l’apprentissage des gestes techniques. La simulation permet en outre une approche efficace de l’étude des facteurs humains, des comportements d’équipe et de la communication avec l’enfant et sa famille, d’importance capitale en réanimation pédiatrique. Elle concerne aussi bien la formation initiale que la formation continue et doit envisager à terme sa place dans l’évaluation objective des professionnels. La mise en place de réseaux de recherche sur la simulation en santé apparaît aujourd’hui indispensable pour permettre l’amélioration des pratiques et de la sécurité des soins.

    ABSTRACT: Septic shock is frequent in children and is associated with high mortality and morbidity rates. Early recognition of severe sepsis improve outcome. Shock index (SI), ratio of heart rate (HR) and systolic blood pressure (SBP), may be a good noninvasive measure of hemodynamic instability that has been poorly studied in children. The aim of the study was to explore the usefulness of SI as an early index of prognosis for septic shock in children. The study was retrospective and performed in 1 pediatric intensive care unit at a university hospital. The following specific data were collected at 0, 1, 2, 4, and 6 hours after admission: HR and SBP for SI calculation and lactate concentration. Patients were divided into 2 groups according to their outcome (death/survival). A total of 146 children admitted with septic shock between January 2000 and April 2010 were included. Shock index was significantly different between survivors and nonsurvivors at 0, 4, and 6 hours after admission (P = 0.02, P = 0.03, and P = 0.008, respectively). Age-adjusted SIs were different between survivors and nonsurvivors at 0 and 6 hours, with a relative risk of death at these time points of 1.85 (1.04-3.26) (P = 0.03) and 2.17 (1.18-3.96) (P = 0.01), respectively. Moreover, an abnormal SI both at admission and at 6 hours was predictive of death with relative risk of 1.36 (1.05-1.76). In our population of children with septic shock, SI was a clinically relevant and easily calculated predictor of mortality. It could be a better measure of hemodynamic status than HR and SBP alone, allowing for the early recognition of severe sepsis.

    ABSTRACT: BACKGROUND: Pediatric sepsis represents an important cause of mortality in pediatric intensive care units (PICU). Although adherence to published guidelines for the management of severe sepsis patients is known to lower mortality, actual adherence to these recommendations is low. The aim of this study was to describe the initial management of pediatric patients with severe sepsis, as well as to describe the main barriers to the adherence to current guidelines on management of these patients. METHODS: A survey using a case scenario to assess the management of a child with severe sepsis was designed and sent out to all PICU medical directors of the 20 institutions member of the "Reseau Mere- Enfant de la Francophonie". Participants were asked to describe in detail the usual management of these patients in their institution with regard to investigations, fluid and catecholamine management, intubation, and specific treatments. Participants were also asked to identify the main barriers to the application of the Surviving Sepsis Campaign guidelines in their center. RESULTS: Twelve PICU medical directors answered the survey. Only two elements of the severe sepsis bundles had a low stated compliance rate: "maintain adequate central venous pressure" and "glycemic control" had a stated compliance of 8% and 25% respectively. All other elements of the bundles had a reported compliance of over 90%. Furthermore, the most important barriers to the adherence to Surviving Sepsis Campaign guidelines were the unavailability of continuous central venous oxygen saturation (ScvO2) monitoring and the absence of a locally written protocol. CONCLUSIONS: In this survey, pediatric intensivists reported high adherence to the current recommendations in the management of pediatric severe sepsis regarding antibiotic administration, rapid fluid resuscitation, and administration of catecholamines and steroids, if needed. Technical difficulties in obtaining continuous ScvO2 monitoring and absence of a locally written protocol were the main barriers to the uniform application of current guidelines. We believe that the development of locally written protocols and of specialized teams could add to the achievement of the goal that every child in sepsis should be treated according to the latest evidence to heighten his chances of survival.

    ABSTRACT: To evaluate the physiological deadspace/tidal volume ratio (VD/VT) as a predictor of extubation failure in 42 ventilated children (median age: 4.75 years). Extubation readiness was determined using the criteria proposed by the 6th International Consensus Conference on Intensive Care Medicine adapted to children. Non-invasive ventilation (NIV) was used in four patients who developed respiratory failure after extubation; none was reintubated. Children who needed NIV to avoid reintubation had a significantly higher VD/VT ratio than those who were extubated without NIV (p < 0.001). The cut-off value of VD/VT ratio was 0.55 and the area under the receiver operating characteristic curve was 0.86. Our findings confirm the good predictive value of weaning success/failure of the VD/VT ratio and suggest its role for predicting the need for NIV after extubation.

    ABSTRACT: To test the performance of PIM2 in French-speaking (FS) paediatric intensive care units (PICUs) and its relative performance when recalibrated using data from FS and Great Britain (GB) PICUs of different size. Consecutive admissions to 15 FS (n = 5,602) and 31 GB PICUs (n = 20,693) from June 2006 to October 2007 were included. The recalibrated PIM2 were applied to PICUs of different size within the FS and GB PICUs and between the two groups. PICU size was defined using number of admissions/month. Discrimination and calibration were evaluated using the area under the ROC curve (AUC) and the goodness-of-fit test, respectively. Logistic regression, funnel plots and standardized W scores were performed in the two groups and between different PICU sizes. In FS PICUs, the original PIM2 had good discrimination (AUC = 0.85) and moderate calibration (p = 0.07). The recalibrated PIM2 scores had good calibration in FS (p = 0.33) and moderate calibration in GB (p = 0.06). Calibration was poor when the recalibrated FS PIM2 was applied to GB (p = 0.02) but good when the GB recalibration was applied to the FS (p = 0.36). Using the original PIM2 coefficients, calibration was poor in large units in both groups but improved following recalibration. There were no effects of PICU size on risk-adjusted mortality in GB and a significant effect in the FS PICUs with a minimum risk-adjusted mortality at about 35 admissions/month. The PIM2 score was valid in the FS population. The recalibration based on GB data could be applied to FS PICUs. Such recalibration may facilitate comparisons between countries.

    ABSTRACT: To report our 10 year experience with noradrenaline use in children with septic shock focusing on doses, routes of administration and complications. Retrospective single-centre review of children with septic shock who received noradrenaline between 2000 and 2010. We identified 144 children with septic shock treated with noradrenaline, in 22% as the first-line drug. The median volume resuscitation before vasoactive agent administration was 50 mL/kg interquartile range [IQR: 30-70]. Mean doses of noradrenaline ranged from 0.5 ± 0.4 μg/kg per min (starting dose) to 2.5 ± 2.2 μg/kg per min (maximum dose). Noradrenaline was administered via peripheral venous access or intra-osseous route in 19% of cases for a median duration of 3 h [IQR: 2-4] without any adverse effects. The use of noradrenaline increased over the study period. Mortality rate was 45% with a significant decrease over the study period. Adverse effects included arrhythmia in two children and hypertension in eight children. None of these arrhythmias required treatment and hypertension resolved with the noradrenaline dose reduction. Higher doses of noradrenaline than those suggested in the literature may be necessary to reverse hypotension and hypoperfusion. The use of noradrenaline through peripheral venous access or intra-osseous route was safe, without any adverse effects.

    ABSTRACT: This study examined (a) how physicians and nurses in France and Quebec make decisions about life-sustaining therapies (LSTs) for critically ill children and (b) corresponding ethical challenges. A focus groups design was used. A total of 21 physicians and 24 nurses participated (plus 9 physicians and 13 nurses from a prior secondary analysis). Principal differences related to roles: French participants regarded physicians as responsible for LST decisions, whereas Quebec participants recognized parents as formal decision-makers. Physicians stated they welcomed nurses' input but found they often did not participate, while nurses said they wanted to contribute but felt excluded. The LST limitations were based on conditions resulting in long-term consequences, irreversibility, continued deterioration, inability to engage in relationships and loss of autonomy. Ethical challenges related to: the fear of making errors in the face of uncertainty; struggling with patient/family consequences of one's actions; questioning the parental role and dealing with relational difficulties between physicians and nurses.

    ABSTRACT: We report on 2 cases associating retinal (RH) and cerebral hemorrhages (CH), which first suggested the diagnosis of shaken baby syndrome (SBS). After an etiologic search, the diagnosis was corrected: the first case was a late hemorrhagic disease of the newborn and the second case hemophilia A. RH is a major feature of SBS, although not pathognomonic. There is no specific RH of SBS but they usually affect the posterior retinal pole. Typically, RHs of SBS are present in both eyes, although unilateral RHs do not exclude the diagnosis of SBS. The relationship between RH and CH has been reported in SBS but also in other diseases. Thus, one must search for hemostasis abnormalities, even though the clinical presentation suggests SBS. Ignoring SBS as well as coming to the conclusion of SBS too quickly should be avoided. Diagnostic difficulties may be related to the number of physicians involved and their interpretation of the facts. These 2 cases underline the need for working as a team that includes hematologists able to interpret coagulation parameters.

    ABSTRACT: Our goal is to assess the prevalence of questioning about the appropriateness of initiating or maintaining life-sustaining treatments (LST) in French-speaking paediatric intensive care units (PICUs) and to evaluate time utilisation related to decision-making processes (DMP). 18-month, multicentre, prospective, descriptive, observational study in 15 French-speaking PICUs. Among the 5,602 children admitted, 410 died (7.3%), including 175 after forgoing LST (42.7% of deaths). LST was questioned in 308 children (5.5%) with a prevalence of 13.3 per 100 patient-days. More than 30% of children survived despite the appropriateness of LST being questioned (23% despite a decision to forgo treatment). Median caregiver time spent on making and presenting the decisions was 11 h per child. In this study, on any given day in each 10-bed PICU, there was more than one child for whom a DMP was underway. Of children, 23% survived despite a decision to forgo LST being made, which underlines the need to elaborate a care plan for these children. Also, DMP represented a large amount of staff time that is undervalued but necessary to ensure optimal palliative practice in PICU.

    ABSTRACT: Early recognition and treatment of meningococcal disease improves its outcome. Haemorrhagic rash is one of the most specific signs that parents can learn to recognise. To determine the percentage of parents able to recognise a haemorrhagic rash and perform the tumbler test. 123 parents of children consulting for mild injuries were interviewed about the significance and recognition of haemorrhagic rash in febrile children. Although 88% of parents undressed their children when they were febrile, it was never to look specifically for a skin rash. Only 7% (95% CI 3% to 12%) were able to recognise a petechial rash and knew the tumbler test. Information campaigns about the significance of haemorrhagic rash and about the tumbler test are needed.

    ABSTRACT: ABSTRACT: Noninvasive positive pressure ventilation (NPPV) refers to the delivery of mechanical respiratory support without the use of endotracheal intubation (ETI). The present review focused on the effectiveness of NPPV in children > 1 month of age with acute respiratory failure (ARF) due to different conditions. ARF is the most common cause of cardiac arrest in children. Therefore, prompt recognition and treatment of pediatric patients with pending respiratory failure can be lifesaving. Mechanical respiratory support is a critical intervention in many cases of ARF. In recent years, NPPV has been proposed as a valuable alternative to invasive mechanical ventilation (IMV) in this acute setting. Recent physiological studies have demonstrated beneficial effects of NPPV in children with ARF. Several pediatric clinical studies, the majority of which were noncontrolled or case series and of small size, have suggested the effectiveness of NPPV in the treatment of ARF due to acute airway (upper or lower) obstruction or certain primary parenchymal lung disease, and in specific circumstances, such as postoperative or postextubation ARF, immunocompromised patients with ARF, or as a means to facilitate extubation. NPPV was well tolerated with rare major complications and was associated with improved gas exchange, decreased work of breathing, and ETI avoidance in 22-100% of patients. High FiO2 needs or high PaCO2 level on admission or within the first hours after starting NPPV appeared to be the best independent predictive factors for the NPPV failure in children with ARF. However, many important issues, such as the identification of the patient, the right time for NPPV application, and the appropriate setting, are still lacking. Further randomized, controlled trials that address these issues in children with ARF are recommended.
