Physical rehabilitation in Brazilian pediatric intensive care units: a multicenter point prevalence study.

OBJECTIVE: To determine the prevalence and factors associated with the physical rehabilitation of critically ill children in Brazilian pediatric intensive care units. METHODS: A 2-day, cross-sectional, multicenter point prevalence study comprising 27 pediatric intensive care units (out of 738) was conducted in Brazil in April and June 2019. This Brazilian study was part of a large multinational study called Prevalence of Acute Rehabilitation for Kids in the PICU (PARK-PICU). The primary outcome was the prevalence of mobility provided by physical therapy or occupational therapy. Clinical data on patient mobility, potential mobility safety events, and mobilization barriers were prospectively collected in patients admitted for ≥ 72 hours. RESULTS: Children under the age of 3 years comprised 68% of the patient population. The prevalence of therapist-provided mobility was 74%, or 277 out of the 375 patient-days. Out-of-bed mobility was most positively associated with family presence (adjusted odds ratios 3.31;95%CI 1.70 - 6.43) and most negatively associated with arterial lines (adjusted odds ratios 0.16; 95%CI 0.05 - 0.57). Barriers to mobilization were reported on 27% of patient-days, the most common being lack of physician order (n = 18). Potential safety events occurred in 3% of all mobilization events. CONCLUSION: Therapist-provided mobility in Brazilian pediatric intensive care units is frequent. Family presence was high and positively associated with out-of-bed mobility. The presence of physiotherapists 24 hours a day in Brazilian pediatric intensive care units may have a substantial impact on the mobilization of critically ill children.

RESUMO Objetivo: Determinar a prevalência e os fatores associados à reabilitação física de crianças em estado grave em unidades de terapia intensiva pediátrica brasileiras. Métodos: Realizou-se um estudo de prevalência pontual multicêntrico, transversal, de 2 dias, abrangendo 27 unidades de terapia intensiva pediátrica (do total de 738) no Brasil em abril e junho de 2019. Este estudo brasileiro fez parte de um grande estudo multinacional chamado Prevalence of Acute Rehabilitation for Kids in the PICU (PARK-PICU). O desfecho primário foi a prevalência de mobilidade proporcionada pela fisioterapia ou pela terapia ocupacional. Foram coletados prospectivamente dados clínicos sobre a mobilidade do paciente, possíveis eventos de segurança de mobilidade e barreiras de mobilização em pacientes admitidos por ≥ 72 horas. Resultados: As crianças com idade inferior a 3 anos eram 68% da população de pacientes. A prevalência de mobilidade fornecida pelo terapeuta foi de 74%, ou 277 dos 375 pacientes-dia. A mobilidade para fora do leito foi mais positivamente associada à presença de familiares (razão de chance ajustada de 3,31; IC95% 1,70 - 6,43) e mais negativamente associada às linhas arteriais (razão de chance ajustada de 0,16; IC95% 0,05 - 0,57). Foram relatadas barreiras à mobilização em 27% dos pacientes-dia, sendo a mais comum a falta de prescrição médica (n = 18). Registaram-se eventuais eventos de segurança em 3% de todos os eventos de mobilização. Conclusão: A mobilidade proporcionada pelo terapeuta nas unidades de terapia intensiva pediátrica brasileiras é frequente. A presença de familiares foi alta e positivamente associada à mobilidade para fora do leito. A presença de fisioterapeutas 24 horas por dia nas unidades de terapia intensiva pediátrica brasileiras pode exercer papel importante na mobilização de crianças em estado grave.

Knowledge regarding extracorporeal membrane oxygenation management among Brazilian pediatric intensivists: a cross-sectional survey / Conhecimento do manejo da oxigenação por membrana extracorpórea de intensivistas pediátricos brasileiros: um inquérito transversal

ABSTRACT Objective: To assess Brazilian pediatric intensivists' general knowledge of extracorporeal membrane oxygenation, including evidence for its use, the national funding model, indications, and complications. Methods: This was a multicenter cross-sectional survey including 45 Brazilian pediatric intensive care units. A convenience sample of 654 intensivists was surveyed regarding their knowledge on managing patients on extracorporeal membrane oxygenation, its indications, complications, funding, and literature evidence. Results: The survey addressed questions regarding the knowledge and experience of pediatric intensivists with extracorporeal membrane oxygenation, including two clinical cases and 6 optional questions about the management of patients on extracorporeal membrane oxygenation. Of the 45 invited centers, 42 (91%) participated in the study, and 412 of 654 (63%) pediatric intensivists responded to the survey. Most pediatric intensive care units were from the Southeast region of Brazil (59.5%), and private/for-profit hospitals represented 28.6% of the participating centers. The average age of respondents was 41.4 (standard deviation 9.1) years, and the majority (77%) were women. Only 12.4% of respondents had taken an extracorporeal membrane oxygenation course. Only 19% of surveyed hospitals have an extracorporeal membrane oxygenation program, and only 27% of intensivists reported having already managed patients on extracorporeal membrane oxygenation. Specific extracorporeal membrane oxygenation management questions were responded to by only 64 physicians (15.5%), who had a fair/good correct response rate (median 63.4%; range 32.8% to 91.9%). Conclusion: Most Brazilian pediatric intensivists demonstrated limited knowledge regarding extracorporeal membrane oxygenation, including its indications and complications. Extracorporeal membrane oxygenation is not yet widely available in Brazil, with few intensivists prepared to manage patients on extracorporeal membrane oxygenation and even fewer intensivists recognizing when to refer patients to extracorporeal membrane oxygenation centers.

RESUMO Objetivo: Avaliar os conhecimentos gerais dos intensivistas pediátricos brasileiros sobre oxigenação por membrana extracorpórea, incluindo evidências de uso, modelo de custeio nacional, indicações e complicações. Métodos: Este estudo foi um inquérito transversal multicêntrico que incluiu 45 unidades de terapia intensiva pediátrica brasileiras. Realizou-se inquérito de conveniência com 654 intensivistas quanto aos seus conhecimentos sobre manejo de pacientes em oxigenação por membrana extracorpórea, suas indicações, complicações, custeio e evidências bibliográficas. Resultados: O inquérito abordou questões relativas aos conhecimentos e à experiência dos intensivistas pediátricos sobre oxigenação por membrana extracorpórea, incluindo dois casos clínicos e seis questões facultativas sobre o manejo de pacientes em oxigenação por membrana extracorpórea. Dos 45 centros convidados, 42 (91%) participaram do estudo, e 412 (63%) dos 654 intensivistas pediátricos responderam ao inquérito. A maioria das unidades de terapia intensiva pediátrica eram da Região Sudeste do Brasil (59,5%), e os hospitais privados com fins lucrativos representavam 28,6% dos centros participantes. A média de idade dos respondentes era de 41,4 (desvio-padrão de 9,1) anos, e a maioria (77%) era mulher. Apenas 12,4% dos respondentes tinham formação em oxigenação por membrana extracorpórea. Dos hospitais pesquisados, apenas 19% tinham um programa de oxigenação por membrana extracorpórea, e apenas 27% dos intensivistas declararam já ter manejado pacientes em oxigenação por membrana extracorpórea. Apenas 64 médicos (15,5%) responderam a questões específicas sobre o manejo de oxigenação por membrana extracorpórea (mediana 63,4%; oscilando entre 32,8% e 91,9%). Conclusão: A maioria dos intensivistas pediátricos brasileiros demonstrou conhecimentos limitados de oxigenação por membrana extracorpórea, incluindo suas indicações e complicações. A oxigenação por membrana extracorpórea ainda não está amplamente disponível no Brasil, com poucos intensivistas preparados para o manejo de pacientes em oxigenação por membrana extracorpórea e ainda menos intensivistas capazes de reconhecer quando devem encaminhar pacientes para centros de oxigenação por membrana extracorpórea.

Development of a prognostic model for pediatric acute liver failure in a Brazilian center

Abstract Objective: Pediatric acute liver failure (PALF) is a heterogeneous, rare, and severe condition, which outcome is survival due to liver spontaneous recovery or death. The patients who do not recover may be allocated to liver transplantation, which is the standard treatment. This study aimed to build a prognostic model to support the clinical decision to indicate liver transplantation for patients with PALF in a Brazilian center. Methods: The authors retrospectively analyzed the clinical variables of 120 patients in the liver transplantation program of the 'Children's Institute of the University of São Paulo, Brazil. The authors conducted a univariate analysis of variables associated with survival in PALF. Logistic multivariate analysis was performed to find a prognostic model for the outcome of patients with pediatric acute liver failure. Results: Risk factors were analyzed using univariate analysis. Two prognostic models were built using multiple logistic regression, which resulted in 2 models: model 1(INR/ALT) and model 2 (INR/Total bilirubin). Both models showed a high sensitivity (97.9%/96.9%), good positive predictive value (89.5%/90.4%), and accuracy (88.4%/88.5%), respectively. The receiver operating characteristic was calculated for both models, and the area under the curve was 0.87 for model 1 and 0.88 for model 2. The Hosmer-Lemeshow test showed that model 1 was good. Conclusion: The authors built a prognostic model for PALF using INR and ALT that can contribute to the clinical decision to allocate patients to liver transplantation.

Prevalence and functional status of children with complex chronic conditions in Brazilian PICUs during the COVID-19 pandemic

Abstract Objective The proportion of children with complex chronic conditions is increasing in PICUs around the world. We determined the prevalence and functional status of children with complex chronic conditions in Brazilian PICUs during the COVID-19 pandemic. Methods The authors conducted a point prevalence cross-sectional study among fifteen Brazilian PICUs during the COVID-19 pandemic. The authors enrolled all children admitted to the participating PICUs with complex chronic conditions on three different days, four weeks apart, starting on April 4th, 2020. The authors recorded the patient's characteristics and functional status at admission and discharge days. Results During the 3 study days from March to June 2020, the authors enrolled 248 patients admitted to the 15 PICUs; 148 had CCC (prevalence of 59.7%). Patients had a median of 1 acute diagnosis and 2 chronic diagnoses. The use of resources/devices was extensive. The main mode of respiratory support was conventional mechanical ventilation. Most patients had a peripherally inserted central catheter (63.1%), followed by a central venous line (52.5%), and 33.3% had gastrostomy or/and tracheostomy. The functional status score was significantly better at discharge compared to admission day due to the respiratory status improvement. Conclusions The prevalence of children with CCC admitted to the Brazilian PICUs represented 59.7% of patients during the COVID-19 pandemic. The functional status of these children improved during hospitalization, mainly due to the respiratory component.

Tracheostomy practices in children on mechanical ventilation: a systematic review and meta-analysis

Abstract Objective: To evaluate current practices of tracheostomy in children regarding the ideal timing of tracheostomy placement, complications, indications, mortality, and success in decannulation. Source of data: The authors searched PubMed, Embase, Cochrane Library, Google Scholar, and complemented by manual search. The guidelines of PRISMA and MOOSE were applied. The quality of the included studies was evaluated with the Newcastle-Ottawa Scale. Information extracted included patients' characteristics, outcomes, time to tracheostomy, and associated complications. Odds ratios (ORs) with 95% CIs were computed using theMantel-Haenszel method. Synthesis of data: Sixty-six articles were included in the qualitative analysis, and 8 were included in the meta-analysis about timing for tracheostomy placement. The risk ratio for "death in hospital outcome" did not show any benefit from performing a tracheostomy before or after 14 days of mechanical ventilation (p = 0.49). The early tracheostomy before 14 days had a great impact on the days of mechanical ventilation (-26 days in mean difference, p < 0.00001). The authors also found a great reduction in hospital length of stay (-31.4 days, p < 0.008). For the days in PICU, the mean reduction was of 14.7 days (p < 0.007). Conclusions: The meta-analysis suggests that tracheostomy performed in the first 14 days of ventilation can reduce the time spent on the ventilator, and the length of stay in the hospital, with no effect on mortality. The decision to perform a tracheostomy early or late may be more dependent on the baseline disease than on the time spent on ventilation.

Extracorporeal membrane oxygenation for respiratory failure in children: the years before and after the 2009 H1N1 pandemic. / Oxigenação por membrana extracorpórea na insuficiência respiratória em crianças: os anos antes e depois da pandemia de H1N1 de 2009.

OBJECTIVE: To evaluate whether there was any impact on the number of pediatric extracorporeal membrane oxygenation runs and survival rates in the years subsequent to the 2009 pandemic. METHODS: We studied two different periods of extracorporeal membrane oxygenation support for respiratory failure in children by analyzing datasets from the Extracorporeal Life Support Organization. Autoregressive integrated moving average models were constructed to estimate the effect of the pandemic. The year 2009 was the year of intervention (the H1N1 epidemic) in an interrupted time series model. Data collected from 2001 - 2010 were considered preintervention, and data collected from 2010 - 2017 were considered postintervention. RESULTS: There was an increase in survival rates in the period 2010 - 2017 compared to 2001 - 2010 (p < 0.0001), with a significant improvement in survival when extracorporeal membrane oxygenation was performed for acute respiratory failure due to viral pneumonia. The autoregressive integrated moving average model shows an increase of 23 extracorporeal membrane oxygenation runs per year, prior to the point of the level effect (2009). In terms of survival, the preslope shows that there was no significant increase in survival rates before 2009 (p = 0.41), but the level effect was nearly significant after two years (p = 0.05), with a 6% increase in survival. In four years, there was an 8% (p = 0.03) increase in survival, and six years after 2009, there was up to a 10% (p = 0.026) increase in survival. CONCLUSION: In the years following 2009, there was a significant, global incremental increase in the extracorporeal membrane oxygenation survival rates for all runs, mainly due to improvements in the technology and treatment protocols for acute respiratory failure related to viral pneumonia and other respiratory conditions.

OBJETIVO: Avaliar o impacto no número de casos de oxigenação por membrana extracorpórea e as taxas de sobrevivência nos anos seguintes à pandemia de H1N1 de 2009. MÉTODOS: Avaliaram-se dois períodos distintos de utilização de oxigenação por membrana extracorpórea como suporte para insuficiência respiratória em crianças, por meio da análise de conjuntos de dados da Extracorporeal Life Support Organization. Foram construídos modelos autorregressivos integrados de médias móveis para estimar os efeitos da pandemia. O ano de 2009 foi o ano de intervenção (epidemia de H1N1) em um modelo de séries temporais interrompidas. Os dados colhidos entre 2001 e 2010 foram considerados pré-intervenção e os obtidos entre 2010 e 2017 como pós-intervenção. RESULTADOS: Em comparação com o período entre 2001 e 2010, o período entre 2010 e 2017 mostrou aumento das taxas de sobrevivência (p < 0,0001), com melhora significante da sobrevivência quando se realizou oxigenação por membrana extracorpórea nos casos de insuficiência aguda por pneumonia viral. Antes do ponto de nível de efeito (2009), o modelo autorregressivo integrado de médias móveis mostrou aumento de 23 casos de oxigenação por membrana extracorpórea ao ano. Em termos de sobrevivência, a curva mostra que não houve aumento significante das taxas de sobrevivência antes de 2009 (p = 0,41), porém o nível de efeito foi próximo à significância após 2 anos (p = 0,05), com aumento de 6% na sobrevivência. Em 4 anos, ocorreu aumento de 8% (p = 0,03) na sobrevivência, e, 6 anos após 2009, a sobrevivência mostrou aumento de até 10% (p = 0,026). CONCLUSÃO: Nos anos após 2009, ocorreu significante e progressivo aumento global das taxas de sobrevivência com oxigenação por membrana extracorpórea para todos os casos, principalmente em razão de melhoras tecnológicas e dos protocolos de tratamento para insuficiência respiratória aguda relacionada à pneumonia viral e a outras condições respiratórias.

Práticas clínicas relacionadas a cânulas nasais de alto fluxo em terapia intensiva pediátrica no Brasil em comparação com as de outros países: um inquérito brasileiro / Clinical practices related to high-flow nasal cannulas in pediatric critical care in Brazil compared to other countries: a Brazilian survey

RESUMO Objetivo: Descrever as práticas clínicas atuais relacionadas à utilização de cânula nasal de alto fluxo por intensivistas pediátricos brasileiros e compará-las com as de outros países. Métodos: Para o estudo principal, foi administrado um questionário a intensivistas pediátricos em países das Américas do Norte e do Sul, Ásia, Europa e Austrália/Nova Zelândia. Comparou-se a coorte brasileira com coortes dos Estados Unidos, Canadá, Reino Unido e Índia. Resultados: Responderam ao questionário 501 médicos, dos quais 127 eram do Brasil. Apenas 63,8% dos participantes brasileiros tinham disponibilidade de cânula nasal de alto fluxo, em contraste com 100% dos participantes no Reino Unido, no Canadá e nos Estados Unidos. Coube ao médico responsável a decisão de iniciar a utilização de uma cânula nasal de alto fluxo segundo responderam 61,2% dos brasileiros, 95,5% dos localizados no Reino Unido, 96,6% dos participantes dos Estados Unidos, 96,8% dos médicos canadenses e 84,7% dos participantes da Índia; 62% dos participantes do Brasil, 96,3% do Reino Unido, 96,6% dos Estados Unidos, 96,8% do Canadá e 84,7% da Índia relataram que o médico responsável era quem definia o desmame ou modificava as regulagens da cânula nasal de alto fluxo. Quando ocorreu falha da cânula nasal de alto fluxo por desconforto respiratório ou insuficiência respiratória, 82% dos participantes do Brasil considerariam uma tentativa com ventilação não invasiva antes da intubação endotraqueal, em comparação com 93% do Reino Unido, 88% dos Estados Unidos, 91,5% do Canadá e 76,8% da Índia. Mais intensivistas brasileiros (6,5%) do que do Reino Unido, Estados Unidos e Índia (1,6% para todos) afirmaram utilizar sedativos com frequência concomitantemente à cânula nasal de alto fluxo. Conclusão: A disponibilidade de cânulas nasais de alto fluxo no Brasil ainda não é difundida. Há algumas divergências nas práticas clínicas entre intensivistas brasileiros e seus colegas estrangeiros, principalmente nos processos e nas tomadas de decisão relacionados a iniciar e desmamar o tratamento com cânula nasal de alto fluxo.

ABSTRACT Objective: To describe current clinical practices related to the use of high-flow nasal cannula therapy by Brazilian pediatric intensivists and compare them with those in other countries. Methods: A questionnaire was administered to pediatric intensivists in North and South America, Asia, Europe, and Australia/New Zealand for the main study. We compared the Brazilian cohort with cohorts in the United States of America, Canada, the United Kingdom, and India Results: Overall, 501 physicians responded, 127 of which were in Brazil. Only 63.8% of respondents in Brazil had a high-flow nasal cannula available, in contrast to 100% of respondents in the United Kingdom, Canada, and the United States. The attending physician was responsible for the decision to start a high-flow nasal cannula according to 61.2% respondents in Brazil, 95.5% in the United Kingdom, 96.6% in the United States, 96.8% in Canada, and 84.7% in India. A total of 62% of respondents in Brazil, 96.3% in the United Kingdom, 96.6% in the United States, 96.8% in Canada, and 84.7% in India reported that the attending physician was responsible for the decision to wean or modify the high-flow nasal cannula settings. When high-flow nasal cannula therapy failed due to respiratory distress/failure, 82% of respondents in Brazil would consider a trial of noninvasive ventilation before endotracheal intubation, compared to 93% in the United Kingdom, 88% in the United States, 91.5% in Canada, and 76.8% in India. More Brazilian intensivists (6.5%) than intensivists in the United Kingdom, United States, and India (1.6% for all) affirmed using sedatives frequently with high-flow nasal cannulas. Conclusion: The availability of high-flow nasal cannulas in Brazil is still not widespread. There are some divergences in clinical practices between Brazilian intensivists and their colleagues abroad, mainly in processes and decision-making about starting and weaning high-flow nasal cannula therapy.

MÉTODOS: Para o estudo principal, foi administrado um questionário a intensivistas pediátricos em países das Américas do Norte e do Sul, Ásia, Europa e Austrália/Nova Zelândia. Comparou-se a coorte brasileira com coortes dos Estados Unidos, Canadá, Reino Unido e Índia. RESULTADOS: Responderam ao questionário 501 médicos, dos quais 127 eram do Brasil. Apenas 63,8% dos participantes brasileiros tinham disponibilidade de cânula nasal de alto fluxo, em contraste com 100% dos participantes no Reino Unido, no Canadá e nos Estados Unidos. Coube ao médico responsável a decisão de iniciar a utilização de uma cânula nasal de alto fluxo segundo responderam 61,2% dos brasileiros, 95,5% dos localizados no Reino Unido, 96,6% dos participantes dos Estados Unidos, 96,8% dos médicos canadenses e 84,7% dos participantes da Índia; 62% dos participantes do Brasil, 96,3% do Reino Unido, 96,6% dos Estados Unidos, 96,8% do Canadá e 84,7% da Índia relataram que o médico responsável era quem definia o desmame ou modificava as regulagens da cânula nasal de alto fluxo. Quando ocorreu falha da cânula nasal de alto fluxo por desconforto respiratório ou insuficiência respiratória, 82% dos participantes do Brasil considerariam uma tentativa com ventilação não invasiva antes da intubação endotraqueal, em comparação com 93% do Reino Unido, 88% dos Estados Unidos, 91,5% do Canadá e 76,8% da Índia. Mais intensivistas brasileiros (6,5%) do que do Reino Unido, Estados Unidos e Índia (1,6% para todos) afirmaram utilizar sedativos com frequência concomitantemente à cânula nasal de alto fluxo. CONCLUSÃO: A disponibilidade de cânulas nasais de alto fluxo no Brasil ainda não é difundida. Há algumas divergências nas práticas clínicas entre intensivistas brasileiros e seus colegas estrangeiros, principalmente nos processos e nas tomadas de decisão relacionados a iniciar e desmamar o tratamento com cânula nasal de alto fluxo.

The Impact of the Novel Coronavirus on Brazilian PICUs.

OBJECTIVES: To study the impact of the coronavirus disease 2019 pandemic, considering the physical distancing and schools closing, on the characteristics of admission and epidemiology on Brazilian PICUs. DESIGN: Observational, multicenter, time series analysis, of electronic medical records from 15 PICU in Brazil. Data consisted of all March, April, and May PICU admissions from 2017 to 2020. SETTING: Fifteen private PICUs in Brazil. PATIENTS: Pediatric patients admitted to the PICU from March to May since 2017. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The period from March 11, 2020, to March 17, 2020, was considered the "intervention point" studied, corresponding to the suspension of school activities and the beginning of physical distancing in Brazil. During the pandemic period studied, there were 28 cases of coronavirus disease 2019 (one death). The mean age was higher (p = 0.000), the length of stay was shorter (p = 0.000), but mortality rates were similar among the periods (p = 0.36). The model estimated a reduction of 1,483 PICU admissions from March 2020 to May 2020. At the end of May, there was an estimated drop of -146.6 bronchiolitis admissions (95% CI, -242.8 to -50.3; p = 0.016); -71 asthma admissions (95% CI, -93.6 to -48.63; p = 0.000); and -59 community-acquired pneumonia admissions (95% CI, -74.7 to -43.3; p = 0.000) per period. The model showed no effect of the "intervention" (physical distancing) on hospitalization rates for epilepsy, diarrhea, sepsis, bacterial meningitis, or surgery when analyzed individually. When assessed together, the model estimated a reduction of 73.6 admissions (95% IC, -132 to -15.2; p = 0.43). CONCLUSIONS: The coronavirus disease 2019 pandemic strongly affected Brazilian PICUs, reducing admissions, length of stay, and the epidemiological profile. The measures to oppose the coronavirus disease 2019 pandemic may have prevented thousands of PICU hospitalizations across the country.

High-flow nasal cannula as a post-extubation respiratory support strategy in preterm infants: a systematic review and meta-analysis / Cânula nasal de alto fluxo como estratégia de suporte respiratório pós-extubação em recém-nascidos prematuros: uma revisão sistemática e metanálise

Abstract Objective: Perform a systematic review and meta-analysis to assess the effectiveness and complications caused by the use of the high-flow nasal cannula in relation to the post-extubation continuous positive airway pressure system in preterm newborns. Data Sources: The searches were performed from January 2013 to December 2018 in the PubMed and Embase databases, as well as a manual search on the internet. Data Synthesis: Two reviewers independently conducted the search, and a third reviewer resolved questions that arose. Ninety-eight articles from the chosen sources were evaluated, and 66 were discarded because they did not meet the inclusion criteria (inadequate topic, age range, or design, in addition to the duplicates). Fifteen articles were read in full, and five more were discarded due to inadequacy to the topic or design. There were ten articles left for systematic review and four for meta-analysis. The study showed non-inferiority in terms of therapeutic failure of the high-flow nasal cannula in relation to continuous positive airway pressure after extubation of preterm newborns. In the meta-analysis, nasal trauma was significantly lower in patients submitted to the high-flow nasal cannula compared to those using continuous positive airway pressure (p < 0.00001). Conclusion: The high-flow nasal cannula is not inferior to continuous positive airway pressure for post-extubation respiratory support in preterm newborns with a gestational age of 32 weeks or less and greater than 28 weeks, in addition to resulting in less nasal trauma.

Resumo Objetivo: Realizar revisão sistemática e metanálise para avaliar efetividade e complicações decorrentes do uso da cânula nasal de alto fluxo em relação ao sistema de pressão positiva contínua de vias aéreas no período pós-extubação em recém-nascidos prematuros. Fontes dos dados: As buscas foram feitas de janeiro de 2013 a dezembro de 2018 nas bases de dados PubMed, Embase e busca manual em arquivos da internet. Resumo dos dados: Dois revisores fizeram a busca de forma independente, um terceiro revisor ficou para dirimir dúvidas. Foram avaliados 98 artigos das fontes escolhidas, 66 descartados por não se enquadrar nos critérios de inclusão (tema, faixa etária ou desenho inadequados, além dos duplicados). Foram lidos 15 artigos na íntegra, foram descartados mais 5 por inadequação ao tema ou desenho. Restaram 10 artigos para revisão sistemática e 4 para metanálise. O estudo evidenciou não inferioridade em termos de falha terapêutica da cânula nasal de alto fluxo em relação ao sistema de pressão positiva contínua de vias aéreas na pós-extubação de recém-nascidos prematuros. Na metanálise, foi significativamente menor o trauma nasal nos pacientes em cânula nasal de alto fluxo em relação ao que usaram sistema de pressão positiva contínua de vias aéreas (p < 0,00001). Conclusão: A cânula nasal de alto fluxo não é inferior ao sistema de pressão positiva contínua de vias aéreas para o suporte respiratório pós-extubação de recém-nascidos prematuros com idade gestacional igual a ou menor do que 32 semanas e maior do que 28 semanas, além de provocar menos trauma nasal.

MANAGEMENT OF ACUTE RESPIRATORY DISTRESS SYNDROME IN A CHILD WITH ADENOVIRUS PNEUMONIA: CASE REPORT AND LITERATURE REVIEW.

OBJECTIVE: To report the case of a child who developed acute respiratory distress syndrome (ARDS) from a pulmonary infection by adenovirus. CASE DESCRIPTION: A female patient aged 2 years and 6 months, weighting 10,295 grams developed fever, productive cough and vomiting, later on progressing to ARDS despite initial therapy in accordance with the institutional protocol for ARDS treatment. The child evolved to refractory hypoxemia and hypercapnia, requiring high parameters of mechanical pulmonary ventilation and use of vasoactive agents. In the treatment escalation, the patient received steroids, inhaled nitric oxide (iNO), was submitted to the prone position, started oscillatory high-frequency ventilation (HFOV) and extracorporeal membrane oxygenation (ECMO) was indicated due to severe refractory hypoxemia. During this time, the patient's clinical response was favorable to HFOV, improving oxygenation index and hypercapnia, allowing the reduction of vasoactive medications and mechanical ventilation parameters, and then the indication of ECMO was suspended. The patient was discharged after 26 days of hospital stay without respiratory or neurological sequelae. COMMENTS: Adenovirus infections occur mainly in infants and children under 5 years of age and represent 2 to 5% of respiratory diseases among pediatric patients. Although most children with adenovirus develop a mild upper respiratory tract disease, more severe cases can occur. ARDS is a serious pulmonary inflammatory process with alveolar damage and hypoxemic respiratory failure; Adenovirus pneumonia in children may manifest as severe pulmonary morbidity and respiratory failure that may require prolonged mechanical ventilation. Exclusive pulmonary recruitment and HFOV are advantageous therapeutic options.

MALIGNANT HYPERTHERMIA IN A CHILD AFTER MAGNETIC RESONANCE IMAGING: A CASE REPORT.

OBJECTIVE: To report on a case of malignant hyperthermia in a child after a magnetic resonance imaging of the skull was performed using sevoflurane anesthesia. CASE DESCRIPTION: A 3-year-old boy admitted to the pediatric intensive care unit after presenting clinical and laboratory findings consistent with unspecified viral meningoencephalitis. While the patient was sedated, a magnetic resonance imaging of the skul was performed using propofol followed by the administration of sevoflurane through a laryngeal mask in order to continue anesthesia. Approximately three hours after the start of the procedure, the patient presented persistent tachycardia, tachypnea, generalized muscular stiffness and hyperthermia. With a diagnostic hypothesis of malignant hyperthermia, dantrolene was then administered, which immediately induced muscle stiffness, tachycardia, tachypnea and reduced body temperature. COMMENTS: Malignant hyperthermia is a rare pharmacogenetic syndrome characterized by a severe hypermetabolic reaction after the administration of halogenated inhalational anesthetics or depolarizing muscle relaxants such as succinylcholine, or both. Although it is a potentially fatal disease, the rapid administration of continued doses dantrolene has drastically reduced the morbidity and mortality of the disease.

Practices related to assessment of sedation, analgesia and delirium among critical care pediatricians in Brazil.

OBJECTIVE: To understand the use of tools, protocols and comfort measures related to sedation/analgesia, and to screen the occurrence of delirium in pediatric intensive care units. METHODS: A survey with 14 questions was distributed by e-mail to Brazilian critical care pediatricians. Eight questions addressed physician and hospital demographics, and six inquired practices to assess sedation, analgesia, and delirium in pediatric intensive care units. RESULTS: Of 373 questionnaires sent, 61 were answered (16.3%). The majority of physicians were practicing in the Southeast region (57.2%). Of these, 46.5% worked at public hospitals, 28.6% of which under direct state administration. Of respondents, 57.1% used formal protocols for sedation and analgesia, and the Ramsay scale was the most frequently employed (52.5%). Delirium screening scores were not used by 48.2% of physicians. The Cornell Assessment of Pediatric Delirium was the score most often used (23.2%). The majority (85.7%) of physicians did not practice daily sedation interruption, and only 23.2% used non-pharmacological measures for patient comfort frequently, with varied participation of parents in the process. CONCLUSION: This study highlights the heterogeneity of practices for assessment of sedation/analgesia and lack of detection of delirium among critical care pediatricians in Brazil.
