Organ donation by Maastricht-III pediatric patients: Recommendations of the Groupe Francophone de Réanimation et Urgences Pédiatriques (GFRUP) and Association des Anesthésistes Réanimateurs Pédiatriques d'Expression Française (ADARPEF). Part II: Specific organizational and technical considerations.

A panel of pediatric experts met to develop recommendations on the technical requirements specific to pediatric controlled donation after planned withdrawal of life-sustaining therapies (Maastricht category III). The panel recommends following the withdrawal of life-sustaining therapies protocol usually applied in each unit, which may or may not include immediate extubation. The organ retrieval process should be halted if death does not occur within 3 h of life-support discontinuation. Circulatory arrest is defined as loss of pulsatile arterial pressure and should be followed by a 5-min no-touch observation period. Death is declared based on a list of clinical criteria assessed by two senior physicians. The no-flow time should be no longer than 30, 45, and 90 min for the liver, kidneys, and lungs, respectively. At present, the panel does not recommend pediatric heart donation after death by circulatory arrest. The mean arterial pressure cutoff that defines the start of the functional warm ischemia (FWI) phase is 45 mmHg in patients older than 5 years and/or weighing more than 20 kg. The panel recommends normothermic regional perfusion in these patients. The FWI phase should not exceed 30 and 45 min for retrieving the pancreas and liver, respectively. There is no time limit to the FWI phase for the lungs and kidneys. The panel recommends routine sharing of experience with Maastricht-III donation among all healthcare institutions involved in order to ensure optimal outcome assessment and continuous discussion on the potential difficulties, notably those related to the management of normothermic regional perfusion in small children.

Organ donation by Maastricht-III pediatric patients: Recommendations of the Groupe Francophone de Réanimation et Urgences Pédiatriques (GFRUP) and Association des Anesthésistes Réanimateurs Pédiatriques d'Expression Française (ADARPEF) Part I: Ethical considerations and family care.

The French Transplant Health Authority (Agence de la Biomédecine) has broadened its organ- and tissue-donation criteria to include pediatric patients whose death is defined by circulatory criteria and after the planned withdrawal of life-sustaining therapies (WLST) (Maastricht category III). A panel of pediatric experts convened to translate data in the international literature into recommendations for organ and tissue donation in this patient subgroup. The panel estimated that, among children aged 5 years or over with severe irreversible neurological injury (due to primary neurological injury or post-anoxic brain injury) and no progression to brain death, the number of potential donors, although small, deserves attention. The experts emphasized the importance of adhering strictly to the collegial procedure for deciding to withdraw life support. Once this decision is made, the available data should be used to evaluate whether the patient might be a potential donor, before suggesting organ donation to the parents. This suggestion should be reserved for parents who have unequivocally manifested their acceptance of WLST. The discussion with the parents should include both the pediatric intensive care unit (PICU) team under the responsibility of a senior physician and the hospital organ- and tissue-procurement team. All recommendations about family care during the end of life of a child in the PICU must be followed. The course and potential challenges of organ donation in Maastricht-III pediatric patients must be anticipated. The panel of experts recommended strict compliance with French recommendations (by the Groupe Francophone de Réanimation et Urgences Pédiatriques) about WLST and providing deep and continuous sedation until circulatory arrest. The experts identified the PICU as the best place to implement life-support discontinuation and emphasized the importance of returning the body to the PICU after organ donation. French law prohibits the transfer of these patients from one hospital to another. A description of the expert-panel recommendations regarding the organization and techniques appropriate for children who die after controlled circulatory arrest (Maastricht III) is published simultaneously in the current issue of this journal..

Withholding and withdrawing treatment in pediatric intensive care. Update of the GFRUP recommendations.

In 2005, the French-speaking task force on pediatric critical and emergency care [Groupe Francophone de Réanimation et d'Urgences Pédiatriques (GFRUP)] issued recommendations on withholding and withdrawing treatments in pediatric critical care. Since then, the French Public Health Code, modified by the laws passed in 2005 and 2016 and by their enactment decrees, has established a legal framework for practice. Now, 15 years later, an update of these recommendations was needed to factor in the experience acquired by healthcare teams, new questions raised by practice surveys, the recommendations issued in the interval, the changes in legislation, and a few legal precedents. The objective of this article is to help pediatric critical care teams find the closest possible compromise between the ethical principles guiding the care offered to the child and the family and compliance with current regulations and laws.

[Can we talk about triage of patients and with whom?] / Peut-on parler de tri des malades et avec qui ?

During the first wave of the Covid-19 epidemic that hit France in the spring of 2020 sparked controversy over the triage of patients in the emergency room. From this controversy, this text will seek to clarify this notion of triage and, and to shed light on the ethical position of bedside physicians who find themselves summited to public health strategies, scientific data, regulatory injunctions and ethical duties.

[Organization of collaborative deliberation for limiting or withholding treatments in children]. / Comment organiser la délibération collégiale pour limiter ou arrêter les traitements en pédiatrie?

In 2005, the French law on patients' rights at the end of life required that decisions to withdraw or withhold life-sustaining treatments be made and carried out by the physician in charge of the patient, after obtaining advice from an independent consulting colleague and the caregiving team. The purpose of this study was to identify theoretical and practical obstacles to this collaborative deliberation and to propose practical guidelines to organize it.

[Neurogenic bladder function disorders in patients with meningomyelocele: S2k guidelines on diagnostics and therapy]. / Neurogene Blasenfunktionsstörungen bei Patienten mit Meningomyelozele : S2k-Leitlinie zu Diagnostik und Therapie.

The treatment of children and adolescents with meningomyelocele has experienced a clear change in the last 30 years. The establishment of pharmacotherapy, clean intermittent catheterization (CIC) and infection prophylaxis have improved the prognosis for patients and have led to new therapeutic strategies. The interdisciplinary cooperation between neonatologists, neurosurgeons, pediatric neurologists, pediatric urologists, pediatric nephrologists, pediatric orthopedists and pediatric surgeons leads to optimization of individualized therapy. These guidelines present definitions and classifications, investigations and timing which are described in detail. The conservative and operative therapy options for neurogenic bladder function disorders are described and discussed with reference to the current literature. The brief overview provides in each case assistance for the treating physician in the care of this patient group and facilitates the interdisciplinary cooperation.

Neuromuscular training based on whole body vibration in children with spina bifida: a retrospective analysis of a new physiotherapy treatment program.

INTRODUCTION: Spina bifida is the most common congenital cause of spinal cord lesions resulting in paralysis and secondary conditions like osteoporosis due to immobilization. Physiotherapy is performed for optimizing muscle function and prevention of secondary conditions. Therefore, training of the musculoskeletal system is one of the major aims in the rehabilitation of children with spinal cord lesions. INTERVENTION AND METHODS: The neuromuscular physiotherapy treatment program Auf die Beine combines 6 months of home-based whole body vibration (WBV) with interval blocks at the rehabilitation center: 13 days of intensive therapy at the beginning and 6 days after 3 months. Measurements are taken at the beginning (M0), after 6 months of training (M6), and after a 6-month follow-up period (M12). Gait parameters are assessed by ground reaction force and motor function by the Gross Motor Function Measurement (GMFM-66). Sixty children (mean age 8.71 ± 4.7 years) who participated in the program until February 2014 were retrospectively analyzed. RESULTS: Walking velocity improved significantly by 0.11 m/s (p = 0.0026) and mobility (GMFM-66) by 2.54 points (p = 0.001) after the training. All changes at follow-up were not significant, but significant changes were observed after the training period. Decreased contractures were observed with increased muscle function. CONCLUSION: Significant improvements in motor function were observed after the active training period of the new neuromuscular training concept. This first analysis of the new neuromuscular rehabilitation concept Auf die Beine showed encouraging results for a safe and efficient physiotherapy treatment program which increases motor function in children with spina bifida.

[French law related to patient's rights and end of life: pediatric intensive care unit's health professionals' opinions]. / Opinions des soignants des réanimations pédiatriques françaises sur l'application de la loi Léonetti.

INTRODUCTION AND OBJECTIVES: To identify the knowledge of caregivers of pediatric intensive care units (PICUs) on the French law related to patients' rights and end of life, their views on withholding/withdrawing life-sustaining treatment (WWLST) decisions, and their feelings about how these decisions were made and implemented. MATERIALS AND METHODS: A multicenter survey in 24 French PICUs during the fourth trimester 2010. RESULTS: One thousand three hundred and thirty-nine professional healthcare workers (1005 paramedics and 334 physicians) responded. Over 85% of caregivers had good knowledge of the WWLST decision-making processes required by law. More than 80% of caregivers accepted mechanical ventilation, hemodiafiltration, or hemodynamic support withdrawal or withholding. Nevertheless, the withdrawal of artificial nutrition and hydration generated reluctance or opposition for the majority of respondents. While paramedics' participation in the decision-making process was deemed necessary by all caregivers, paramedics found more often than physicians that they were insufficiently involved. The quality of end-of-life care was judged very positively by caregivers. The answers on how WWLST was applied suggest very different interpretations of the law. Some caregivers respect the principles of palliative care as stated in the public health code and 40% of doctors and 64% of caregivers consider it "acceptable" to hasten death if resulting from a collaborative decision-making process. CONCLUSION: This study is the first to show that caregivers of French PICUs have good knowledge of the French law concerning the end of life. Yet, there is still confusion about the limits of practice during the end-of-life period.

[The consulting physician for withdrawal of life-sustaining treatments in children]. / Le médecin consultant pour les limitations et les arrêts de traitement en pédiatrie.

In 2005, the French law on patients' rights at the end of life ratified that decisions to withdraw or withhold life-sustaining treatments must be made and carried out by the physician in charge of the patient, after obtaining the advice of an independent consulting colleague. The purpose of this text is to put forward the perspective of a pediatric multidisciplinary workshop regarding the role of the consulting physician and to propose guidelines to help choose this consultant.

[Hyperthermia in spina bifida patients treated with oxybutynin]. / Temperaturerhöhung unter Oxybutynin bei Patienten mit Spina bifida.

Paraplegic spina bifida patients often suffer from disturbed sweat secretion in the paretic regions. A diminished sweat production of caudal parts of the body is compensated by an increased secretion of sweat in parts cranial to the lesion to maintain temperature homoeostais. If the sweat secretion is blocked by anticholinergic effects of urotherapeutic drugs (for instance oxybutynin) hyperthermia can result as a side effect as these casuistic examples show.An 8-year-old girl with a lumbar meningomyelocele and a neurogenic bladder reported a dry skin and hyperthermia up to 38,5°C during oral therapy with oxybutynin (0.4 mg per kg body weight) during hot summer days. Similar symptoms were shown by a 7-year-old male patient with a sacral meningomyelocele and neurogenic bladder on oral therapy of 0.35 mg oxybutynin per kg body weight. A 4-year-old female patient with lumbar spina bifida and neurogenic bladder reacted to intravesical administration of 0.4 and 0.3 mg per kg body weight during early summertime with hyperthermia up to 38°C. In this case the medication had been started in wintertime and was primarily well tolerated.Hyperthermia under treatment with anticholinergic drugs has mainly been published for geriatric patients with sometimes fatal outcome. In the pediatric literature there is only one warning regarding the use of oxybutynin in children with spina bifida living in high temperature regions. It is remarkable that hyperthermia can also happen after intravesical administration of oxybutynin in usual dosage.

Noradrenaline use for septic shock in children: doses, routes of administration and complications.

AIM: To report our 10 year experience with noradrenaline use in children with septic shock focusing on doses, routes of administration and complications. METHODS: Retrospective single-centre review of children with septic shock who received noradrenaline between 2000 and 2010. RESULTS: 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. CONCLUSION: 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.

Longitudinal study on specific IgE against natural rubber latex, banana and kiwi in patients with spina bifida.

OBJECTIVE: Up to 2 out of 3 spina bifida (sb) patients with natural rubber latex (NRL) antibodies (ab) have crossreacting IgE-ab against tropical fruit, due to structural homologies between several NRL antigens and allergenic fruit proteins. It is essential to investigate whether the patients were first sensitized against NRL or fruit, to give recommendations for an evidence-based prophylaxis. PATIENTS AND METHODS: We investigated sera of 96 sb patients for specific IgE ab against NRL, banana and kiwi as examples for crossreacting fruit by FEIA (ImmunoCAP System, Phadia). These tests were repeated up to 3 times (mean after 2 years, maximum after 7 years). RESULTS: In the first testing only 2 of 50 NRL-IgE negative patients (4%) had ab against banana or kiwi. 4 of the 46 NRL-IgE positive patients (8%) showed ab against banana (2) or kiwi (2), 3 (7%) against both fruit. Symptoms of fruit allergy were presented by 3 patients, all symptomatic patients had high levels of specific fruit-ab. In the follow-up study 2 patients with low sensitization against NRL lost their NRL ab and their fruit ab, another 2 only the fruit ab, whereas 4 NRL-sensitized patients newly developed ab against banana and 1 against kiwi. Only 2 patients developed ab against fruit without being sensitized against NRL. 7 out of 10 patients with banana and kiwi ab were atopics. CONCLUSIONS: In most cases the sensitization against fruit follows the NRL sensitization. There is no need to recommend sb patients without NRL sensitization to primarily avoid tropical fruit.

Effects of latex avoidance on latex sensitization, atopy and allergic diseases in patients with spina bifida.

BACKGROUND: Ten years ago, avoidance measures such as the performance of latex-free operations were implemented in children with spina bifida. Since then, latex sensitization and latex allergy have decreased in this high-risk group. OBJECTIVE: To study the effect of primary latex-free prophylaxis on the prevalence of allergic diseases and atopy as a marker for sensitization spreading in children with spina bifida. METHODS: One hundred and twenty children with spina bifida born after the introduction of latex-free prophylaxis and operated on under latex-free conditions ('current group') were examined for latex sensitization, latex allergy, sensitization to aero- and food allergens and allergic diseases. Results were compared to a 'historic' (not latex-free operated) group of children with spina bifida and comparable age (n = 87) and to a recent sample of children from the general population (n = 12,403). RESULTS: In comparison with the 'historic group', latex sensitization (55% vs 5%, P < 0.001) and latex allergy (37% vs 0.8%, P < 0.001) were significantly reduced in the 'current group'. Furthermore, a significant reduction could be demonstrated for sensitization to aeroallergens (41.4% vs 20.8%, P = 0.001) and for allergic diseases (35% vs 15%, P = 0.001). The prevalence for atopy, sensitization to aero-/foodallergens and for allergic diseases in children of the 'current group' was similar to those in children of the weighted population sample. CONCLUSIONS: Latex avoidance in children with spina bifida prevents latex sensitization and latex allergy. Additionally, it also seems to prevent sensitization to other allergens and allergic diseases which might be explained by the prevention of sensitization spreading.

[Why teams in charge of children after a pediatric intensive care unit stay do not take into account the treatment limitation decisions previously made by intensivists]. / Pourquoi les décisions de limitation des traitements en réanimation ne sont-elles pas partagées avec les professionnels assurant les soins de l'enfant avant et après la réanimation?

UNLABELLED: The fact that some children may survive despite a limitation of treatment decision (LTD) made in the pediatric intensive care unit (PICU) is a recent concern. A previous study pointed out that the teams in charge of children after the PICU stay did not take previous PICU LTDs into account. PURPOSE: To identify the problems different units experience in cooperating with the PICU team, in order to increase the continuity of care for these children. STUDY DESIGN: Qualitative single-center study, using semi-structured interviews with physicians in charge of children who were discharged from the PICU even though a LTD was made. RESULTS: Nine pediatric subspecialists (hemato-oncologists, neurologists, and neurosurgeons) were interviewed, producing a corpus of approximately 80 pages of typed text. Three conflictual situations were identified by these physicians. The most frequently reported situation was being asked by the PICU team to give expert advice on a patient's prognosis, before a LTD was made. The 2 others had to defend a true care plan for children who were transferred to the PICU and designing a new care plan for children who were discharged from the PICU after a LTD was made. CONCLUSION: The medical reasoning model that is used for LTDs in the PICU generates conflictual situations when compared to the models that are used in other specialties. These models represent various expressions of subjectivity, as in any medical decision. Acknowledging this fact could facilitate its integration into clinical practice and should improve authentic debates that are necessary to ensure continuity of care for these children.

[What become the decisions of limitation of treatments after discharge from the paediatric intensive care unit?]. / Que deviennent les décisions de limitation ou d'arrêt des traitements actifs à la sortie de réanimation pédiatrique ?

UNLABELLED: 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.

Quantitative analysis of immunoglobulin E reactivity profiles in patients allergic or sensitized to natural rubber latex (Hevea brasiliensis).

BACKGROUND: Characterized native and recombinant Hevea brasiliensis (rHev b) natural rubber latex (NRL) allergens are available to assess patient allergen sensitization profiles. OBJECTIVE: Quantification of individual IgE responses to the spectrum of documented NRL allergens and evaluation of cross-reactive carbohydrate determinants (CCDs) for more definitive diagnosis. METHODS: Sera of 104 healthcare workers (HCW; 51 German, 21 Portuguese, 32 American), 31 spina bifida patients (SB; 11 German, 20 Portuguese) and 10 Portuguese with multiple surgeries (MS) were analysed for allergen-specific IgE antibody (sIgE) to NRL, single Hev b allergens and CCDs with ImmunoCAP technology. RESULTS: In all patient groups rHev b 5-sIgE concentrations were the most pronounced. Hev b 2, 5, 6.01 and 13 were identified as the major allergens in HCW and combined with Hev b 1 and Hev b 3 in SB. In MS Hev b 1 displayed an intermediate relevance. Different sIgE antibody levels to native Hevea brasiliensis (nHev b) 2 and rHev b 6.01 allowed discrimination of SB with clinical relevant latex allergy vs. those with latex sensitization. Sensitization profiles of German, Portuguese and American patients were equivalent. rHev b 5, 6.01 and nHev b 13 combined detected 100% of the latex-allergic HCW and 80.1% of the SB. Only 8.3% of the sera showed sIgE response to CCDs. CONCLUSIONS: Hev b 1, 2, 5, 6.01 and 13 were identified as the major Hev b allergens and they should be present in standardized latex extracts and in vitro allergosorbents. CCDs are only of minor relevance in patients with clinical relevant latex allergy. Component-resolved diagnostic analyses for latex allergy set the stage for an allergen-directed immunotherapy strategy.

Natural rubber latex sensitisation and allergy in patients with spina bifida, urogenital disorders and oesophageal atresia compared with a normal paediatric population.

BACKGROUND: Natural rubber latex (NRL) contains proteins which, after repeated contact with latex products and an allergic predisposition (atopy), can lead to sensitisation (specific IgE against NRL proteins) or allergy (type 1 allergy with symptoms from urticaria to allergic shock). Spina bifida patients are known to be a high risk group for latex allergy and sensitisation due to numerous operations beginning soon after birth. In the study presented here we compared spina bifida patients with patients who also underwent repeated operations beginning soon after birth (urological malformations) or underwent surgery once in the neonatal period but had numerous anaesthesias because of repeated treatment with a bougie (oesophageal atresia). In this setting the influence of surgery and anaesthesia on NRL-sensitisation was investigated. MATERIALS AND METHODS: We investigated the prevalence of NRL-specific IgE (> 0.35 kU/l, ImmunoCAP system, Pharmacia) in a normal paediatric population (neither atopic nor having undergone surgery) (group I), spina bifida patients (group II), children with urogenital malformations (group III) and children with oesophago-tracheal malformations (group IV). RESULTS: The highest rate of NRL-sensitised patients was found in the spina bifida group (II) (48 %), followed by groups III and IV with 17 % each, compared to 4 % for the control group. NRL-allergic reactions were noted only in the patients with spina bifida and the urological malformation group (18 % in group II, 8 % in Group III). Apart from atopy the number of operations could be identified as a risk factor for the development of NRL-sensitisation and allergy (group II, III). The prevalence of latex allergy was lower after repeated anaesthesia (group IV) than after repeated surgery. CONCLUSIONS: In addition to the known high risk group of spina bifida patients, other patients with congenital malformations and early surgery also have a significant risk for latex sensitisation. When treating patients with malformations requiring repeated surgery, prophylactic measures similar to those for spina bifida patients should be considered.

Are the GFRUP's recommendations for withholding or withdrawing treatments in critically ill children applicable? Results of a two-year survey.

OBJECTIVE: To evaluate feasibility of the guidelines of the Groupe Francophone de Réanimation et Urgence Pédiatriques (French-speaking group of paediatric intensive and emergency care; GFRUP) for limitation of treatments in the paediatric intensive care unit (PICU). DESIGN: A 2-year prospective survey. SETTING: A 12-bed PICU at the Hôpital Jeanne de Flandre, Lille, France. PATIENTS: Were included when limitation of treatments was expected. RESULTS: Of 967 children admitted, 55 were included with a 2-day median delay. They were younger than others (24 v 60 months), had a higher paediatric risk of mortality (PRISM) score (14 v 4), and a higher paediatric overall performance category (POPC) score at admission (2 v 1); all p<0.002. 34 (50% of total deaths) children died. A limitation decision was made without meeting for 7 children who died: 6 received do-not-resuscitate orders (DNROs) and 1 received withholding decision. Decision-making meetings were organised for 31 children, and the following decisions were made: 12 DNROs (6 deaths and 6 survivals), 4 withholding (1 death and 3 survivals), with 14 withdrawing (14 deaths) and 1 continuing treatment (survival). After limitation, 21 (31% of total deaths) children died and 10 survived (POPC score 4). 13 procedures were interrupted because of death and 11 because of clinical improvement (POPC score 4). Parents' opinions were obtained after 4 family conferences (for a total of 110 min), 3 days after inclusion. The first meeting was planned for 6 days after inclusion and held on the 7th day after inclusion; 80% of parents were immediately informed of the decision, which was implemented after half a day. CONCLUSIONS: GFRUPs procedure was applicable in most cases. The main difficulties were anticipating the correct date for the meeting and involving nurses in the procedure. Children for whom the procedure was interrupted because of clinical improvement and who survived in poor condition without a formal decision pointed out the need for medical criteria for questioning, which should systematically lead to a formal decision-making process.

[Non-invasive ventilation in infants with severe infection presumably due to respiratory syncytial virus: feasibility and failure criteria]. / Ventilation non invasive des nourrissons ayant une infection respiratoire sévère présumée à virus respiratoire syncitial: faisabilité et critères d'échec.

UNLABELLED: Beneficial effect of continuous positive airway pressure (CPAP) during non invasive ventilation (NIV) has been reported in infants with respiratory syncytial virus (RSV) infection, but no study has analyzed the predictors of its failure. OBJECTIVE: To evaluate the feasibility of NIV and to determine NIV failure criteria. POPULATION AND METHODS: All infants hospitalized in one PICU with presumed RSV infection between 2002 and 2006 were prospectively included. When respiratory support was needed, NIV was first started according to a pre-established protocol. RESULTS: One hundred and one infants, 43 females, 58 males, median age 49 days (range: 10-334), median weight 3.9 kg (range: 2,4-12) were included. RSV infection was confirmed in 84/101. Sixty-seven infants were transported by the paediatric medical transport system, 27 with NIV and 15 with invasive ventilation (IV). Fifteen infants were in IV at admission, 69 received NIV during their PICU stay (12 secondarily requiring IV) and 17 were never ventilated. A significant decrease in PCO2 with increase in pH was observed within 2 hours of NIV. Parameters associated with NIV failure were apneas, high values of admission PCO2 and H24 PRISM score. The 17 non-ventilated infants were older and had a lower severity score than those who were ventilated. CONCLUSION: In infants with RSV and needing respiratory support, NIV represented the sole method of respiratory support in 68% of cases. NIV failure criteria were apneas, high values of admission PCO2 and H24 PRISM score.
