Erros de medicação e eventos adversos relacionados a medicamentos são comuns em pacientes hospitalizados. O risco de ocorrer problemas com a população pediátrica é cerca de três vezes maior do que com a população adulta, especialmente em unidades de terapia intensiva, onde os pacientes são submetidos a grande número de prescrições de medicamentos intravenosos, com baixo índice terapêutico e formas farmacêuticas adaptadas. A farmácia clínica tem como objetivo introduzir o farmacêutico clínico junto à equipe multidisciplinar de saúde no sentido de intervir, prevenindo problemas relacionados a medicamentos à farmacoterapia (PRF), otimizando-a e contribuindo para a segurança do paciente. O presente estudo teve como objetivo avaliar a implantação e o impacto das intervenções da farmácia clínica no Centro de Terapia Intensiva-Pediátrico (CTIP) do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP). Trata-se de estudo prospectivo, observacional e descritivo que incluiu crianças de zero a dezoito anos, no período de um ano. Foi aplicada a ferramenta Failure Mode and Effects Analysis (FMEA - Análise dos Modos de Falha e seus Efeitos) no início do estudo para avaliar os riscos relacionados aos medicamentos no CTIP e orientar a atuação da farmácia clínica, em que o farmacêutico avaliou as prescrições diárias e realizou intervenções junto à equipe multidisciplinar. Foram acompanhadas 162 crianças e avaliadas 1586 prescrições com uma taxa de PRF de 12,42% (IC95% 10,50-14,04). Foram realizadas 197 intervenções com custo salvo de R$15.118,73. Os principais tipos de intervenções foram relacionados à indicação e necessidade do medicamento. A partir destas, os grupos foram divididos em pacientes com PRF e sem PRF. Foram detectadas diferenças significativas nas seguintes variáveis: peso, idade, tempo de internação, tempo de acompanhamento, custo total, custo salvo pelas intervenções, gravidade dos pacientes avaliada pelo escore PRISM e PELOD, quantidade total de medicamentos utilizados e quantidade de medicamentos potencialmente perigosos e endovenosos contínuos. Além disso, houve diferenças significativas na taxa de óbito e nas categorias diagnósticas entre os grupos. A implantação do serviço de farmácia clínica no CTIP mostrou impacto positivo na redução de riscos relacionados a todo o processo de utilização de medicamentos. As intervenções do farmacêutico clínico identificaram e preveniram PRF, promovendo o uso racional de medicamentos e contribuindo para a redução de custos associados à prescrição médica. / Medication errors and adverse events related to drugs are common in hospitalized patients. The potential risk for medication errors in pediatric patients is about three times higher than in adults, especially in intensive care units, where patients are subjected to a large number of intravenous drug prescriptions, with low therapeutic index and adapted pharmaceutical forms. Clinical pharmacy aims to introduce the clinical pharmacist in a multidisciplinary health team in order to intervene, preventing drug-related problems (DRPs) and optimize pharmacotherapy, contributing to patient safety. This study aimed to assess the implementation and the impact of clinical pharmacy interventions in the Pediatric Intensive Care Unit (PICU) of Hospital das Clinicas of Ribeirao Preto Medical School, University of São Paulo (HCFMRP-USP). This was a prospective, observational and descriptive study which included children from zero to eighteen years of age, over a one year period. Failure Mode and Effects Analysis Tool (FMEA) was applied at the beginning of the study to assess the risks related to medicines in the PICU and to guide clinical pharmacy work, where the pharmacist evaluated daily prescriptions and made interventions along with a multidisciplinary team. One thousand five hundred and eighty-six prescriptions of 162 children were assessed, and a DRPs rate of 12.42% (95% CI - 10.50 to 14.04) was found. One hundred ninety-seven interventions were performed, with a cost saving of R$ 15,118.73. The main types of interventions were related to indication and necessity of the drug. From these, the groups were divided in patients with DRPs and without DRPs. Significant differences were found in weight, age, time of hospitalization, time of follow-up, total cost, costs saved by interventions, severity of patients assessed by PRISM and PELOD scores, total amount of medications used, and number of potentially dangerous and continuous intravenous medications. In addition, there were significant differences in mortality rate and diagnostic categories between groups. The implementation of clinical pharmacy service in the PICU showed a positive impact on patients\' treatment. The clinical pharmacist interventions identified and prevented DRPs, promoting the rational use of medications and contributing to the reduction of costs associated with medical prescription.

Des études adultes sur l’œdème pulmonaire lésionnel et le Syndrome de Détresse Respiratoire Aiguë ont mené à l’établissement de recommandations sur les stratégies de ventilation mécanique à employer chez ces patients. Cependant, il n’est pas clair si les recommandations adultes sont également bénéfiques pour l’enfant. Objectif Décrire les stratégies de ventilation mécanique employées chez les enfants atteints d’un œdème pulmonaire lésionnel. Méthodes Étude épidémiologique transversale tenue dans 59 unités de Soins Intensifs Pédiatriques de 12 pays en Amérique du Nord et en Europe. Six jours d’étude ont eu lieu entre juin et novembre 2007. Les enfants atteints d’un œdème pulmonaire lésionnel étaient inclus et des données sur la sévérité de leur maladie, les paramètres de ventilation mécanique et les thérapies adjuvantes employées ont été recueillies. Résultats Des 3823 enfants dépistés, 414 (10.8%) avaient un œdème pulmonaire lésionnel et 165 (40%) ont été inclus dans l’étude (124 étaient sous ventilation mécanique conventionnelle, 27 sous ventilation à haute fréquence par oscillation et 14 sous ventilation non invasive). Dans le groupe sous ventilation conventionnelle, 43.5% étaient ventilés avec un mode contrôlé à pression, le volume courant moyen était de 8.3±3.3 ml/kg et l’utilisation de la PEP et FiO2 était hétérogène. Conclusions Cette étude démontre une hétérogénéité dans les stratégies de ventilation mécanique employées chez les enfants souffrant d’un œdème pulmonaire lésionnel. Celle-ci pourrait être en partie reliée à la robustesse des critères diagnostiques actuellement utilisés pour définir l’ALI/SDRA. Une évaluation rigoureuse de ces stratégies est nécessaire pour guider la standardisation des soins et optimiser l’issue de ces patients. / Acute Lung Injury and Acute Respiratory Distress Syndrome are life-threatening conditions frequently leading to respiratory support with mechanical ventilation. Studies on mechanical ventilation strategies in adult patients have led to lung protective ventilation recommendations. However, there are few pediatric clinical trials on optimal mechanical ventilation management in Acute Lung Injury and it is still unclear if strategies studied in adults are equally beneficial to children. Objective Describe mechanical ventilation strategies in Acute Lung Injury in children. Methods Cross-sectional study for six 24-hour periods from June to November 2007 across 59 Pediatric Intensive Care Units in 12 countries in North America and Europe. We identified children meeting Acute Lung Injury criteria and collected detailed information on illness severity, mechanical ventilation support and use of adjunctive therapies. Results Of 3823 patients screened, 414 (10.8%) were diagnosed with Acute Lung Injury and 165 were included in the study (124 received conventional mechanical ventilation, 27 high frequency oscillatory ventilation, 14 non-invasive mechanical ventilation). In the conventional mechanical ventilation group, 43.5% were ventilated in a pressure control mode, the mean tidal volume was 8.3±3.3 ml/kg and there was no clear relationship between PEEP and FiO2 delivery. Conclusions Our study reveals inconsistent mechanical ventilation practice and use of adjunctive therapies in children with Acute Lung Injury. Rigorous evaluation of ventilator management strategies in children with an Acute Lung Injury are urgently needed to guide standardization of care and optimize clinical outcomes.

There are families that can overcome the difficulties of hospitalization, however, others are unstructured, since the hospitalization of the child can have repercussions throughout the family system. This is why, during the hospitalization of a baby, the support of the social network becomes essential for the mother and for the other relatives. There are several support networks that can be detected during the hospitalization of a baby: a network of relatives, friends, professionals and internal networks. Thus, the present study aimed to elaborate a graphical representation of the results of the social support network of mothers who had their babies hospitalized in a Pediatric or Neonatal Intensive Care Unit. As specific objectives, this study considered: elucidate the feelings of mothers regarding the experience of child care in a Pediatric or Neonatal Intensive Care Unit; to know the factors that favor or hinder the experience of mothers during the period of hospitalization of their baby; and, to know the relationships established by the mothers in the hospital environment. A qualitative research was conducted through a semi-structured interview and through the application of an adaptation of Sluzki's Minimal Relations Map (1997), with the participation of nine mothers of infants who were admitted to six different Pediatric and Neonatal ICUs. Data collection was performed from June to September 2016, and originated two articles. In the first article. Data resulting from the interview were coded by content analysis and resulted in three categories: When the real does not correspond to the expected: the mother facing the need for hospitalization of the baby in the ICU; The exchange of a lullaby pack by a roller coaster of emotions; and, What can mitigate the strong emotions of the roller coaster?: the importance of support. In the second article, already from the analysis of the map, which was given by incidence, it was highlighted in the family quadrant, that the husband was the most cited as being the closest relative and that most supported the mother; in the friends' quadrant, some participants mentioned having close friends and receiving support from them during the baby's hospitalization; in the family quadrant of other patients: some participants mentioned that they had a close relationship with the other mothers and that they supported her during ICU stay; And in the ICU team quadrant, among the professionals, the nurse perceived the closest one perceived by the mothers. It was concluded that it is difficult for mothers not to be able to take their babies home after birth. They revealed feelings such as fear, insecurity, fear of the baby's death, impotence and guilt. The mothers experienced a sense of loss of control of the situation, concern for other children and need for support. It was possible to elucidate that the husband, in most cases, plays the most important role of support, both socially and emotionally, and failing him, the second person closest is the maternal grandmother of the baby, but the other family and friends also play the role of social support and material aid. Proximity to other mothers is greater when hospitalization is long or occurs outside the home city, and the team also exerts important support for mothers. Professionals can minimize the suffering of mothers and their families through simple initiatives, with a view to greater reception, always prioritizing clear and welcoming communication. As a way to broaden the reflections, according to the objective, a graphic representation of the results of the Minimum Adapted Relationship Map was prepared, which was presented to the students of the health area and will be exposed in the halls of the Teaching Institution Centro Universitário Franciscano. Descriptors: Pediatric Intensive Care Unit; Neonatal Intensive Care Unit; Hospitalized Child; Social network; Social support; Maternity / A experiência da hospitalização de um bebê em Unidade de Terapia Intensiva, para as mães e suas famílias, é um momento difícil. Existem famílias que conseguem superar as dificuldades da hospitalização, porém, outras se desestruturam, pois a internação do filho pode repercutir em todo o sistema familiar. Motivo pelo qual, durante a hospitalização de um bebê o apoio da rede social se torna essencial para a mãe e para os demais familiares. São várias as redes de apoio que podem ser detectadas durante a internação de um bebê: rede de familiares, de amigos, de profissionais e redes internas. Assim, o presente estudo teve como objetivo geral elaborar uma representação gráfica dos resultados da rede de apoio social de mães que tiveram seus bebês hospitalizados em uma Unidade de Terapia Intensiva Pediátrica ou Neonatal Como objetivos específicos, este estudo considerou: elucidar os sentimentos das mães em relação à vivência de cuidado do filho em uma Unidade de Terapia Intensiva Pediátrica ou Neonatal; conhecer os fatores que favorecem ou dificultam a experiência das mães no período de internação do seu bebê; e, conhecer as relações estabelecidas pelas mães no ambiente hospitalar. Foi realizada uma pesquisa qualitativa, por meio de entrevista semiestruturada e através da aplicação de uma adaptação do Mapa Mínimo de Relações de Sluzki (1997), com a participação de nove mães de bebês que foram internados em seis diferentes UTIs, Pediátricas e Neonatais. A coleta dos dados foi realizada no período de junho a setembro de 2016, e originou dois artigos. No primeiro artigo, os dados resultantes da entrevista foram codificados pela análise de conteúdo e resultaram em três categorias: Quando o real não corresponde ao esperado: a mãe diante da necessidade de internação do bebê na UTI; A troca do embalo do ninar por uma montanha russa de emoções; e, O que pode atenuar as fortes emoções da montanha russa?: a importância do apoio. Já no segundo artigo, a partir da análise do mapa, que se deu por incidência, destacou-se no quadrante dos familiares, que o esposo foi o mais citado como sendo o familiar mais próximo e que mais apoiou a mãe; no quadrante dos amigos, algumas participantes citaram ter amigos bem próximos e terem recebido apoio deles durante a internação do bebê; no quadrante de familiares de outros pacientes: algumas participantes citaram que tiveram uma relação bem próxima com as outras mães e que estas lhe apoiaram bastante durante a internação na UTI; e, no quadrante equipe da UTI, entre os profissionais, o mais próximo percebido pelas mães foi o enfermeiro. Concluiu-se que é difícil para as mães não poder levar os seus bebês para casa após o nascimento. Elas revelaram sentimentos como medo, insegurança, temor da morte do bebê, impotência e culpa. As mães vivenciaram a sensação de perda de controle da situação, preocupação com os outros filhos e necessidade de apoio. Foi possível elucidar que o marido, na maioria dos casos, desempenha a função mais importante de apoio, tanto social quanto emocional, e na falta dele, a segunda pessoa mais próxima é a avó materna do bebê, porém, os demais familiares e amigos também desempenham a função de apoio social e ajuda material. A proximidade com as outras mães é maior quando a hospitalização é longa ou se dá fora da cidade de origem, e a equipe também exerce um importante apoio às mães. Os profissionais podem minimizar o sofrimento das mães e de seus familiares por meio de iniciativas simples, com vistas a um maior acolhimento, priorizando sempre por uma comunicação clara e acolhedora. Como forma de ampliar as reflexões, de acordo com o objetivo, foi confeccionado uma representação gráfica dos resultados do Mapa Mínimo de Relações Adaptado, o qual foi apresentado aos estudantes da área da saúde e ficará exposto nos corredores da Instituição de Ensino Centro Universitário Franciscano.

A influência das características laborais sobre a saúde mental dos trabalhadores pode decorrer de inúmeros fatores ou formas de organização do trabalho. Na atualidade, verifica-se os crescentes índices de sintomas psíquicos entre determinadas categorias profissionais, com destaque para os trabalhadores de saúde atuantes em ambiente hospitalar Objetivo: Este estudo objetivou identificar a ocorrência de Transtornos Mentais Comuns (TMC), a ocorrência da síndrome de Burnout, e a associação de ambos os transtornos nos trabalhadores de enfermagem, bem como elaborar propostas de intervenção para redução do desgaste psíquico. Metodologia: Trata-se de um estudo exploratório, transversal com abordagem quanti-qualitativa. A pesquisa foi realizada em Hospital Público Universitário especializado em cardiologia, pneumologia e cirurgias cardíacas e torácicas. A amostra foi composta por trabalhadores de enfermagem que atuam em unidades de terapia semi-intensiva e intensiva pediátrica e neonatal, perfazendo um total de 92 participantes. Para a coleta de dados quantitativos foram utilizados: instrumento de caracterização sócio demográfica, Self-Reporting Questionnaire (SRQ-20), e o Maslach Burnout Inventory (MIB). Para os dados qualitativos, optou-se pela técnica de grupo focal, conduzido por questões norteadoras, com uma amostra de 17 trabalhadores de enfermagem. O período de coleta foi nos meses de junho e julho de 2012. Resultados: A análise dos resultados evidenciou a ocorrência de TMC em 44,60%(41) dos trabalhadores e a ocorrência de Burnout em 8,7%(8) trabalhadores. Houve associação estatística entre os TMC e o Burnout p=0,003, considerando nível de significância de 5%. Em relação aos TMC, as respostas dos trabalhadores foram distribuídas de acordo com os quatro grupos de sintomas avaliados pelo SRQ-20: Grupo somático, Decréscimo de energia vital, Humor depressivo-ansioso e Pensamentos depressivos. Em relação à sindrome de Burnout, os trabalhadores foram avaliados considerando-se a ocorrência de escores alto nas três dimensões (Desgaste Emocional, Despersonalização e Reduzida Realização Profissional) ou em uma delas apenas. Não foi constatada associação entre os transtornos e as variáveis sócio-demográficas. Houve associação entre ambos os transtornos. As sessões de grupo focal evidenciaram propostas de intervenção mediante três temas que emergiram das discussões: Aprender a lidar com a criança cardiopata grave, Receber o reconhecimento profissional e Repensar a gestão de pessoas. Conclusão: Os achados, em conjunto, evidenciam necessidade de medidas protetoras à saúde mental do trabalhador que assiste crianças cardiopatas graves. Palavras-chave: Estresse psicológico, Esgotamento profissional, Equipe de enfermagem, Hospitais públicos, Unidades de terapia intensiva pediátrica, Unidade de terapia intensiva neonatal, Saúde do trabalhador. / The influence of work characteristics on mental health workers may be due to numerous factors or forms of work organization. At present, there is the growing rates of psychiatric symptoms among certain professions, especially health workers working in hospitals Objective: This study aimed to identify the occurrence of Common Mental Disorders (CMD), the occurrence of Burnout, and the association of both disorders among nursing staff, as well as elaborate proposals for intervention to reduce wear psychic. Methodology This is an exploratory study, cross-sectional with quantitative and qualitative approach. The research was conducted in a public University Hospital specialized in cardiology, pulmonology, thoracic and cardiac surgery. The sample consisted of nursing workers of care units, semi-intensive and intensive, pediatric and neonatal, making a total of 92 participants. For quantitative data collection was used: instrument of socio demographic, Self-Reporting Questionnaire (SRQ-20), and the Maslach Burnout Inventory (MIB). For qualitative data, we chose the technique of focal group, conducted by leading questions, with a sample of 17 nurse workers. The collection period was between June and July, 2012. Results The result of the analysis revealed the occurrence of CMD in 44.60% (41) of the workers and the occurrence of Burnout in 8.7% (8) of the workers. There was a statistical association between CMD and Burnout p = 0.003, considering level of significance 5%. Regarding CMD, the answer of the workers was distributed according to the four groups of prognostic evaluated by the SRQ-20: Somatic Group, Decrease of vital energy, Anxious-depressive humor and Depressive thoughts. Regarding Burnout syndrome, workers were evaluated considering the occurrence of high scores in all three dimensions (Emotional Exhaustion, Depersonalization, and Reduced Professional Accomplishment) or only in one of them. There was no association between the disorders and sociodemographic variables. There was an association between both disorders. The focal group sessions revealed proposals for intervention through three issues that emerged from the discussions: Learn to deal with severe heart disease children, professional acknowledgment and rethink people management. Conclusion: Findings, during the sessions, highlight the need for protective measures of mental health for workers who assist children with heart disease

Trata-se de pesquisa de natureza qualitativa, do tipo estudo de caso, realizado no centro de terapia intensiva pediátrico oncológico de um hospital de referência no tratamento de câncer localizado na Cidade do Rio de Janeiro. A produção de dados envolveu as técnicas de observação simples, com registros em diário de campo, e entrevista semiestruturada com 25 membros da equipe de enfermagem e 10 familiares acompanhantes de crianças com câncer internadas no referido centro de terapia intensiva. Após organização e identificação dos dados, estes foram submetidos à análise temática de conteúdo segundo Bardin, emergindo-se as seguintes categorias: O familiar da criança com câncer até a entrada no centro de terapia intensivo pediátrico oncológico e as interações do familiar acompanhante e membros da equipe de enfermagem no cuidado à criança com câncer no Centro de Terapia Intensiva Oncológico. A partir dos depoimentos dos familiares acompanhantes e da equipe de enfermagem constatou-se que no cuidado a criança hospitalizada no CTIP a interação entre ambos favorece sua adaptação ao ambiente, que envolve inúmeros procedimentos e rotinas, demandando suporte emocional e conforto viabilizado pela presença do familiar e conhecimento técnico e científico da equipe de enfermagem. Assim, conclui-se que o centro de terapia intensivo pediátrico oncológico representa um espaço de interação do familiar acompanhante com a equipe de enfermagem no cuidado a criança com câncer, fundamentado na escuta atenta, viabilizada pelo diálogo que possibilita a troca de conhecimentos do familiar da criança com sua experiência, sentimentos e expectativas. Tal processo tem início com o adoecimento e conta com a equipe de enfermagem que tem como meta o cuidado integral à mesma, incluindo suporte e orientações ao familiar da criança, elemento fundamental no seu processo de hospitalização e tratamento. / The study aimed to analyze the limits and possibilities of the presence of an accompanying family member in the care of children with cancer in the pediatric oncologic intensive care unit and as specific objectives: to describe the care of children in the pediatric oncologic intensive care unit in the nursing team and companion family member´s point of view; identify the nursing team´s point of view about the presence of an accompanying family member in the pediatric oncologic intensive care unit and to know how the accompanying family member sees his presence in the pediatric oncologic intensive care unit. It´s a qualitative research, a case study, carried out at the pediatric oncologic intensive care unit of a reference hospital in the treatment of cancer located in the city of Rio de Janeiro. The data production involved the simple observation techniques, with records in field diary, and semi-structured interview with 25 members of the nursing team and 10 accompanying family members of hospitalized children with cancer in that intensive therapy unit. After data identification and organization, these were submitted to thematic content analysis according to Bardin, emerging the following categories: the family of the child with cancer to the entrance in the pediatric oncologic intensive care unit and the family member´s interactions and nursing team members in the care for children with cancer in the Oncologic Intensive Care Unit. From the testimonies of the accompanying family members and nursing team we found that in the care of children hospitalized in the CTIP interaction between them favors its adaptation to the environment, involving numerous procedures and routines, requiring emotional support and comfort made possible by the familiar member presence and scientific and technical knowledge of the nursing team. Thus, it is concluded that the pediatric oncologic intensive care unit is an accompanying family member interaction space with the nursing team in care of children with cancer, based on attentive listening, made possible by dialogue that enables the exchange of the knowledge of the family member with his experience, feelings and expectations. This process begins with the illness and has the nursing team that aims to the comprehensive care to it, including support and guidance to the child's family, a key element in the process of hospitalization and treatment.

M.Cur. / The Rights of the Child are summarised in the Convention of the Rights of the Child. The Convention sets the basic rights of children for their survival, development and protection. The purpose of this research is to investigate the view of the Nursing staff working in Paediatric Intensive Care Unit in a Private Clinic on the West Rand, regarding the rights of the child, and to describe the view of the Nursing staff regarding the rights of the child as applicable within the context of a Paediatric Intensive Care Unit in a Private Clinic on the West Rand.

Introduction : La tolérance induite par l’utilisation prolongée des opiacés peut se traduire par un syndrome de sevrage aux opiacés (SDSO). Il n’existe aucun consensus sur la méthode idéale de sevrage des opiacés pour prévenir le SDSO chez la clientèle des soins intensifs pédiatriques (SIP). L’objectif de cette étude était de comparer l’efficacité de deux stratégies de sevrage des opiacés, à savoir la méthadone et la morphine administrées par voie entérale, à prévenir le SDSO. Devis : Essai clinique randomisé à double aveugle chez les enfants sous ventilation mécanique hospitalisés aux SIP. Méthode : Nous avons comparé la durée totale de sevrage, l’incidence et la sévérité du SDSO chez les enfants à risque au moins modéré de SDSO sevrés avec la méthadone et la morphine entérales. Les enfants inclus étaient ceux hospitalisés au Centre Hospitalier Universitaire Sainte-Justine ou au Centre Mère-Enfant Soleil de Québec entre le 1er novembre 2003 et le 31 mai 2009. Résultats : Quarante-huit patients (22 groupe méthadone et 26 groupe morphine) ont été inclus et 30 patients ont complété le protocole de sevrage (16 groupe méthadone et 14 groupe morphine). La durée médiane de sevrage était de 5.4 jours dans le groupe méthadone comparativement à 5.8 jours pour le groupe morphine (p=0.49). Il n’y avait pas de différence dans l’incidence du SDSO (62.5% versus 42.9%; p=0.46), et dans sa sévérité (12.5% versus 14.3% de SDSO sévère; p=0.62). Conclusion : L’efficacité d’un sevrage standardisé des opiacés par la méthadone était comparable à celle de la morphine. / Background : The prolonged use of opioids has been associated with opioid tolerance and weaning is necessary to prevent opioid withdrawal symptoms (OWS). Little research exist for an ideal effective opioid taper to reduce the prevalence of OWS. This study aim to compare the effectiveness of two opioid taper strategies, enteral’s methadone and morphine, in preventing the occurrence of OWS among pediatric intensive care patients. Design: Double-blinded randomized controlled trial in mechanically ventilated children (MVCs) hospitalized in 2 pediatric intensive care units (PICU). Methods: Eligible patients were MVCs at moderate risk of OWS admitted in PICU of the Centre Hospitalier Universitaire Sainte-Justine or the Centre Mère-Enfant Soleil de Québec between November 1, 2003 and May 31, 2009. We assessed the total weaning duration, the OWS’s incidence and the OWS’s severity in a methadone’s and a morphine’s taper schedule. Results: Forty-eight patients were included, 22 in the methadone group and 26 in the morphine group and 30 patients completed the weaning protocol (16 methadone and 14 morphine). The median duration of weaning was 5.4 days among methadone’s patients as opposed to 5.8 days among morphine’s group (p=0.49). There was no statistical difference between groups for OWS’s incidence (62.5% vs 42.9%; p=0.46), nor for its severity (12.5% vs 14.3% of severe OWS; p=0.62). Conclusion: The use of a standardized opioid weaning protocol with enteral methadone was as effective as the enteral morphine one’s to prevent OWS. Further studies are needed to determine an ideal opioid taper to reduce OWS.

Objectives: The objectives of this research were to describe the interactions (formal and informal) in which macrocognitive functions occur and their location on a pediatric intensive care unit (PICU); describe challenges and facilitators of macrocognition using three constructs of space syntax (openness, connectivity, and visibility); and analyze the health care built environment (HCBE) using those constructs to explicate influences on macrocognition. Background: In high reliability, complex industries, macrocognition is an approach to develop new knowledge among interprofessional team members. Although macrocognitive functions have been analyzed in multiple health care settings, the effect of the HCBE on those functions has not been directly studied. The theoretical framework, “Macrocognition in the Health Care Built Environment” (m-HCBE) addresses this relationship. Methods: A focused ethnographic study was conducted, including observation and focus groups. Architectural drawing files used to create distance matrices and isovist field view analyses were compared to panoramic photographs and ethnographic data. Results: Neighborhoods comprised of corner configurations with maximized visibility enhanced team interactions as well as observation of patients, offering the greatest opportunity for informal situated macrocognitive interactions (SMIs). Conclusions: Results from this study support the intricate link between macrocognitive interactions and space syntax constructs within the HCBE. These findings help to advance the m-HCBE theory for improving physical space by designing new spaces or refining existing spaces, or for adapting IPT practices to maximize formal and informal SMI opportunities; this lays the groundwork for future research to improve safety and quality for patient and family care.

co-diplomation avec l'Université de Lille (France) / Introduction : La dexmédétomidine, un agoniste α-2 adrénergique, est de plus en plus utilisée pour la sédation et l’analgésie des nouveau-nés nécessitant un support ventilatoire grâce à son absence d’effet dépressif respiratoire. Cependant, elle impacte le système cardio-vasculaire via le système nerveux autonome et pourrait modifier la balance des systèmes sympathiques et parasympathiques (S/PS) et ainsi augmenter la survenue de bradycardie et d’hypotension. Objectifs : Cette étude a pour objectif de décrire l’utilisation de la dexmédétomidine et d’analyser l’impact de la perfusion continue sur le système cardio-vasculaire et sur la balance du système S/PS des nouveau-nés admis aux soins intensifs pédiatriques. Méthodes : Nous avons inclus les nouveau-nés (< 28 jours) qui ont reçu une perfusion de dexmédétomidine. Les données ont été collectées à partir d’une base de données haute résolution qui collecte prospectivement, outre les données du dossier clinique informatisé, toutes les données issues des moniteurs et des pousses-seringues. La balance S/PS a été estimée via l’analyse de la variabilité du rythme cardiaque (VRC) sur les électrocardiogrammes, extraits de la base de données, en calculant le rapport basses fréquences / hautes fréquences (LH/HF). Les concentrations plasmatiques (CP) de dexmédétomidine ont été simulées en utilisant un modèle pharmacocinétique de population développé dans une population similaire à la nôtre. Les variables ont été comparées sur différentes périodes au cours des 12 premières heures de perfusion à l'aide d'analyses ANOVA et la relation avec les variables pharmacocinétiques a été calculée par régression linéaire. Résultats : Vingt-trois nouveau-nés ont été inclus dans l’étude. Par rapport aux valeurs témoins, la fréquence cardiaque (FC) a diminué de 19±4 bpm (p=0,002) et la pression artérielle moyenne (PAM) a diminué de 8,6±2,5 mmHg (p=0,023) pendant les 12 premières heures de perfusion. La FC diminuait avec l’augmentation de la CP simulée (coefficient de régression de -8,6 [95% IC : -1,9 ; -6,3]). Le rapport LF/HF a montré une tendance à la diminution sans retrouver de différence statistiquement significative (p=0,077). Conclusion : La FC et la PAM semblent diminuées sous dexmédétomidine tout en restant dans des valeurs normales pour le nouveau-né. L’ampleur de la diminution de la FC semble reliée à l’augmentation des CP. De plus, la tendance de diminution de la balance S/PS suggère une réduction du contrôle sympathique chez le nouveau-né recevant la dexmédétomidine. Cependant, l’ensemble de ces résultats doit encore être confirmé par des études plus larges et prospectives. / Introduction: Dexmedetomidine, an adrenergic α-2 agonist, has been increasingly used for sedation and analgesia in neonates due to its lack of respiratory depressant effect. However, it impacts the cardiovascular system via the autonomic nervous system. It could modify the sympathetic/parasympathetic balance (S/PS balance) and result in an increased risk of bradycardia and hypotension. Objectives: This study aimed to describe the utilization of intravenous dexmedetomidine infusion and characterize its impact on the hemodynamics, including S/PS balance, in critically ill neonates. Methods: We retrospectively included neonates (<28 days) who received a dexmedetomidine infusion. Data were collected from a high-fidelity database that prospectively collects all data from the monitors, infusion pumps, and electronic medical records. The S/PS balance was assessed by analyzing heart rate variability from database electrocardiograms. This was done using the low/high frequency (LF/HF) ratio with frequency band adapted for neonatal population. Dexmedetomidine plasma concentrations (PC) were simulated using a published population pharmacokinetic model. The variables were compared at different times during the first 12 hours of infusion using ANOVA analyses and their association with pharmacokinetics variables was evaluated using linear regression. Results: A total of 23 neonates were included. When compared to baseline values, heart rate (HR) values decreased by 19±4 bpm (p=0.002), and mean arterial pressure (MAP) decreased by 8.6±2.5 mmHg (p=0.023) 12 hours following the initiation of infusion. HR decreased proportionally with increased simulated PC over 12 hours (regression coefficient: -8.6 [95% IC: -10.9 - 6.3]). The LF/HF ratio tended to decrease over the same period, although this was not statistically significant (p=0.077). Conclusion: In critically ill neonates, HR and MAP decreased on dexmedetomidine infusion but remained within normal neonatal values. The decrease in HR was associated with higher simulated PC. Moreover, the decreasing trend of S/PS balance suggest a reduction in sympathetic control in the neonate receiving dexmedetomidine. However, these results need to be confirmed with larger prospective studies.
