The experience of families in face of the finiteness of their children in the process of adopting palliative care.

OBJECTIVE: To reveal the experience of family members after learning their child would adopt palliative care. METHOD: Phenomenological research on Heidegger's perspective. The participants were eleven family members of children who were recommended palliative care in the Pediatric Intensive Care Unit from a university hospital in southern Brazil. The statements were obtained in a semi-structured interview, from January to November/2017, and submitted to Heidegger's theoretical-philosophical analysis. Research approved by the institution's Ethical Committee. RESULTS: The communication of palliative care triggers the perception of the child's existencial facticity in the Family, revealing reactions explained in the thematic dimensions: "Coping with the finiteness of the child when confronted with the proposal of adopting palliative care" and "The need for compassionate and attentive care". FINAL CONSIDERATIONS: Phenomenology allows us to understand the parent's existential purpose. An understanding perspective can help interdisciplinary teams to communicate the adoption of palliative care in a sensitive and ethical way, focusing on the best interest of the child.

Efeitos da doença crítica no status funcional de crianças com histórico de prematuridade / Effects of critical illness on the functional status of children with a history of prematurity

RESUMO Objetivo: Avaliar os efeitos da doença crítica no status funcional de crianças de zero a 4 anos com e sem histórico de prematuridade após a alta da unidade de terapia intensiva pediátrica. Métodos: Estudo transversal secundário aninhado a uma coorte de caráter observacional de sobreviventes de uma unidade de terapia intensiva pediátrica. A avaliação funcional aconteceu por meio da Functional Status Scale no período de até 48 horas após a alta da unidade de terapia intensiva pediátrica. Resultados: Participaram do estudo 126 pacientes, sendo 75 prematuros e 51 nascidos a termo. Na comparação entre o status funcional basal e o status funcional da alta da unidade de terapia intensiva pediátrica, ambos os grupos apresentaram diferenças significativas (p < 0,001). Na alta da unidade de terapia intensiva pediátrica, as alterações funcionais aumentaram significativamente em ambos os grupos (p < 0,001). Os pacientes prematuros apresentaram maior declínio funcional na alta da unidade de terapia intensiva pediátrica (61%). Nos pacientes nascidos a termo, houve correlação significativa entre Pediatric Index of Mortality, tempo de sedação, tempo de ventilação mecânica e tempo de internação com os desfechos funcionais (p = 0,05). Conclusão: A maior parte dos pacientes estudados apresentou declínio funcional na alta da unidade de terapia intensiva pediátrica. Apesar de os pacientes prematuros apresentarem maior declínio funcional na alta, os pacientes nascidos a termo apresentaram influência do tempo de sedação e do tempo de uso de ventilação mecânica nos seus status funcionais.

ABSTRACT Objective: To evaluate the effects of critical illness on the functional status of children aged zero to 4 years with or without a history of prematurity after discharge from the pediatric intensive care unit. Methods: This was a secondary cross-sectional study nested in an observational cohort of survivors from a pediatric intensive care unit. Functional assessment was performed using the Functional Status Scale within 48 hours after discharge from the pediatric intensive care unit. Results: A total of 126 patients participated in the study, 75 of whom were premature, and 51 of whom were born at term. Comparing the baseline and functional status at pediatric intensive care unit discharge, both groups showed significant differences (p < 0.001). Preterm patients exhibited greater functional decline at discharge from the pediatric intensive care unit (61%). Among patients born at term, there was a significant correlation between the Pediatric Index of Mortality, duration of sedation, duration of mechanical ventilation and length of hospital stay with the functional outcomes (p = 0.05). Conclusion: Most patients showed a functional decline at discharge from the pediatric intensive care unit. Although preterm patients had a greater functional decline at discharge, sedation and mechanical ventilation duration influenced functional status among patients born at term.

Use of magnesium sulfate in continuous infusion in patients with severe acute asthma, in a pediatric emergency room.

INTRODUCTION: Asthma is a chronic disease, of high prevalence, with important morbidity and that can lead to death in childhood. The use of intravenous magnesium sulfate has been indicated in cases refractory to the initial management with inhaled bronchodilators and corticosteroids. OBJECTIVE: To evaluate the use of magnesium sulfate in continuous infusion (50 mg/kg/h in 4 h) in children with severe acute asthma in a pediatric emergency room. LOCATION: Ten-bed general pediatric emergency room, university hospital, tertiary, in southern Brazil. PATIENTS: All children over 2 years old with severe acute asthma refractory to the initial treatment who received a continuous infusion of magnesium sulfate at a dose of 50 mg/kg/h in 4 h, from April 2017 to October 2019. CONCLUSION: Based on this study, the use of continuous intravenous magnesium sulfate proved to be well tolerated, leading to improved respiratory status, and can be considered as a satisfactory adjunctive therapy in the management of severe acute asthma.

Accuracy of stridor-based diagnosis of post-intubation subglottic stenosis in pediatric patients / Precisão do diagnóstico de estenose subglótica pós-intubação com base em estridorem pacientes pediátricos

Abstract Objective To assess the accuracy of stridor in comparison to endoscopic examination for diagnosis of pediatric post-intubation subglottic stenosis. Method Children who required endotracheal intubation for >24 h were included in this prospective cohort study. Children were monitored daily and underwent flexible fiberoptic laryngoscopy after extubation. Those with moderate-to-severe abnormalities underwent another examination 7-10 days later. If lesions persisted or symptoms developed, laryngoscopy under general anesthesia was performed. Patients were assessed daily for stridor after extubation. Results A total of 187 children were included. The incidence of post-extubation stridor was 44.38%. Stridor had a sensitivity of 77.78% (95% confidence interval [95% CI]: 51.9-92.6) and specificity of 59.18% (95% CI: 51.3-66.6) in detecting subglottic stenosis. The positive predictive value was 16.87% (95% CI: 9.8-27.1), and the negative predictive value was 96.15% (95% CI: 89.9-98.8). Stridor persisting longer than 72 h or starting more than 72 h post-extubation had a sensitivity of 66.67% (95% CI: 41.2-85.6), specificity of 89.1% (95% CI: 83.1-93.2), positive predictive value of 40.0% (95% CI: 23.2-59.3), and negative predictive value of 96.07% (95% CI: 91.3-98.4). The area under the receiver operating characteristic (ROC) curve was 0.78 (95% CI: 0.65-0.91). Conclusions Absence of stridor was appropriate to rule out post-intubation subglottic stenosis. The specificity of this criterion improved when stridor persisted longer than 72 h or started more than 72 h post-extubation. Thus, endoscopy under general anesthesia can be used to confirm subglottic stenosis only in patients who develop or persist with stridor for more than 72 h following extubation.

Resumo Objetivo Analisar a precisão do estridor em comparação com o exame endoscópico no diagnóstico de estenose subglótica pós-intubação em crianças. Método Foram incluídas neste estudo de coorte prospectivo crianças que necessitaram de intubação endotraqueal por mais de 24 horas. Elas foram monitoradas diariamente e submetidas à nasofibrolaringoscopia flexível após a extubação. As crianças com anomalias moderadas foram submetidas a outro exame sete a 10 dias depois. Caso as lesões persistissem ou os sintomas evoluíssem, a laringoscopia era realizada com anestesia geral. Os pacientes foram avaliados diariamente quanto ao estridor após a extubação. Resultados Participaram 187 crianças. A incidência de estridor após a intubação foi de 44,38%. O estridor apresentou uma sensibilidade de 77,78% (intervalo de confiança de 95% [IC]: 51,9-92,6) e especificidade de 59,18% (IC: 51,3-66,6) na detecção de SGS. O valor preditivo positivo foi de 16,87% (IC: 9,8-27,1) e o valor preditivo negativo (VPN) foi de 96,15% (IC: 89,9-98,8). O estridor que persistiu por mais de 72 horas ou que começou 72 horas após a extubação teve uma sensibilidade de 66,67% (IC: 41,2-85,6), especificidade de 89,1% (IC: 83,1-93,2), valor preditivo positivo de 40,0% (IC: 23,2-59,3) e valor preditivo negativo de 96,07% (IC: 91,3-98,4). A área sob a curva de característica de operação do receptor (ROC) foi de 0,78 (IC: 0,65-0,91). Conclusões A ausência de estridor foi adequada para descartar a estenose subglótica pós-intubação. A especificidade desse critério melhorou quando o estridor perdurou por mais de 72 horas ou começou mais de 72 horas após a extubação. Assim, a endoscopia com anestesia geral pode ser utilizada para confirmar a estenose subglótica somente em pacientes que desenvolveram ou continuaram com estridor por mais de 72 horas após a extubação.

Accidental strangulation in children by the automatic closing of a car window. / Estrangulamento acidental em crianças por fechamento automático de vidro de carro.

Among the main causes of death in our country are car accidents, drowning and accidental burns. Strangulation is a potentially fatal injury and an important cause of homicide and suicide among adults and adolescents. In children, its occurrence is usually accidental. However, in recent years, several cases of accidental strangulation in children around the world have been reported. A 2-year-old male patient was strangled in a car window. The patient was admitted to the pediatric intensive care unit with a Glasgow Coma Scale score of 8 and presented with progressive worsening of respiratory dysfunction and torpor. The patient also presented acute respiratory distress syndrome, acute pulmonary edema and shock. He was managed with protective mechanical ventilation, vasoactive drugs and antibiotic therapy. He was discharged from the intensive care unit without neurological or pulmonary sequelae. After 12 days of hospitalization, he was discharged from the hospital, and his state was very good. The incidence of automobile window strangulation is rare but of high morbidity and mortality due to the resulting choking mechanism. Fortunately, newer cars have devices that stop the automatic closing of the windows if resistance is encountered. However, considering the severity of complications strangulated patients experience, the intensive neuro-ventilatory and hemodynamic management of the pathologies involved is important to reduce morbidity and mortality, as is the need to implement new campaigns for the education of parents and caregivers of children, aiming to avoid easily preventable accidents and to optimize safety mechanisms in cars with electric windows.

Estrangulamento acidental em crianças por fechamento automático de vidro de carro / Accidental strangulation in children by the automatic closing of a car window

RESUMO Entre as principais causas de morte em nosso meio, situam-se acidentes automobilísticos, afogamento e queimaduras acidentais. O estrangulamento é uma injúria potencialmente fatal, além de importante causa de homicídio e suicídio em adultos e adolescentes. Em crianças, sua ocorrência é usualmente acidental. No entanto, nos últimos anos, vários casos de estrangulamento acidental em crianças ao redor do mundo têm sido reportados. Paciente masculino de 2 anos de idade foi vítima de estrangulamento em vidro do carro. Admitido na unidade de terapia intensiva pediátrica com Escala de Coma de Glasgow de 8, piora progressiva da disfunção respiratória e torpor. Paciente apresentou quadro de Síndrome da Angústia Respiratória Aguda, edema agudo de pulmão e choque. Foi manejado com ventilação mecânica protetora, drogas vosoativas e antibioticoterapia. Recebeu alta da unidade de terapia intensiva sem sequelas neurológicas ou pulmonares. Após 12 dias de internação, teve hospitalar alta para casa em ótimo estado. A incidência de estrangulamento por vidro de automóvel é rara, mas de alta morbimortalidade, devido ao mecanismo de asfixia ocasionado. Felizmente, os automóveis mais modernos dispõem de dispositivos que interrompem o fechamento automático dos vidros se for encontrada alguma resistência. No entanto, visto a gravidade das complicações de pacientes vítimas de estrangulamento, é significativamente relevante o manejo intensivo neuroventilatório e hemodinâmico das patologias envolvidas, para redução da morbimortalidade, assim como é necessário implementar novas campanhas para educação dos pais e cuidadores das crianças, visando evitar acidentes facilmente preveníveis e otimizar os mecanismos de segurança nos automóveis com vidros elétricos.

Undersedation is a risk factor for the development of subglottic stenosis in intubated children / Subsedação é um fato de risco para o desenvolvimento de estenose subglótica em crianças intubadas

Abstract Objective: To analyze the level of sedation in intubated children as a risk factor for the development of subglottic stenosis. Methods: All patients between 30 days and 5 years of age who required endotracheal intubation in the pediatric intensive care unit between 2013 and 2014 were included in this prospective study. They were monitored daily and COMFORT-B scores were obtained. Flexible fiber-optic laryngoscopy was performed within eight hours of extubation, and repeated seven to ten days later if the first examination showed moderate to severe laryngeal injuries. If these lesions persisted and/or if the child developed symptoms in the follow-up period, microlaryngoscopy under general anesthesia was performed to evaluate for subglottic stenosis. Results: The study included 36 children. Incidence of subglottic stenosis was 11.1%. Children with subglottic stenosis had a higher percentage of COMFORT-B scores between 23 and 30 (undersedated) than those who did not develop subglottic stenosis (15.8% vs. 3.65%, p = 0.004). Conclusion: Children who developed subglottic stenosis were less sedated than children who did not develop subglottic stenosis.

Resumo Objetivo: Analisar o nível de sedação em crianças intubadas como um fator de risco para o desenvolvimento de estenose subglótica (ES). Métodos: Todos os pacientes entre 30 dias e cinco anos que necessitaram de intubação endotraqueal na Unidade de Terapia Intensiva Pediátrica entre 2013 e 2014 foram incluídos neste estudo prospectivo. Eles foram monitorados diariamente e foram obtidos os escores da escala Comfort-B. Foi feita laringoscopia com tubo flexível de fibra óptica em oito horas da extubação e repetida 7-10 dias depois, caso o primeiro exame tivesse mostrado lesões laríngeas moderadas a graves. Caso essas lesões tivessem persistido e/ou caso a criança tivesse desenvolvido sintomas no período de acompanhamento, foi feita microlaringoscopia sob anestesia geral para avaliar a ES. Resultados: Incluímos 36 crianças. A incidência da ES foi de 11,1%. As crianças com ES apresentaram um maior percentual de escores da escala Comfort-B entre 23 e 30 (subsedados) que os que não desenvolveram ES (15,8% em comparação com 3,65%, p = 0,004). Conclusão: As crianças que desenvolveram ES foram menos sedadas do que as que não desenvolveram.

Association of endotracheal tube repositioning and acute laryngeal lesions during mechanical ventilation in children.

The objective of this study is to determine the incidence of post-extubation acute laryngeal lesions in a pediatric intensive care unit (PICU) and potential risk factors. Children, aged 28 days to 5 years, admitted to the PICU who required endotracheal intubation for at least 24 h were enrolled. Exclusion criteria were a previous intubation, history of laryngeal disease, current or past tracheostomy, the presence of craniofacial malformations and patients considered on palliative care. All patients underwent flexible fiber-optic laryngoscopy (FFL) not later than 8 h after extubation. A blinded researcher identified and classified laryngeal lesions based on recorded media. 231 children were enrolled between November 2005 and December 2015. At FFL examination, 102 children (44.15%) presented moderate to severe laryngeal lesions. On a multivariable analysis, we found that for each additional day with repositioning of the endotracheal tube, there was an increase of 7.3% (RR 95% CI 1.012-1.137; P = 0.018) on the baseline risk of developing moderate to severe acute laryngeal lesions. Furthermore, for each additional dose of sedation per day of intubation, there was also an increase of 3.5% on the same baseline risk (RR 95% CI 1.001-1.070; P = 0.041). The amount of tube repositioning episodes and the need for extra doses of sedation (as a proxy for possible agitation) were found to be associated with acute laryngeal lesions. Adequate sedation and minimized tube repositioning should be pursued to possibly prevent the development of post-extubation airway compromise.

Undersedation is a risk factor for the development of subglottic stenosis in intubated children.

OBJECTIVE: To analyze the level of sedation in intubated children as a risk factor for the development of subglottic stenosis. METHODS: All patients between 30 days and 5 years of age who required endotracheal intubation in the pediatric intensive care unit between 2013 and 2014 were included in this prospective study. They were monitored daily and COMFORT-B scores were obtained. Flexible fiber-optic laryngoscopy was performed within eight hours of extubation, and repeated seven to ten days later if the first examination showed moderate to severe laryngeal injuries. If these lesions persisted and/or if the child developed symptoms in the follow-up period, microlaryngoscopy under general anesthesia was performed to evaluate for subglottic stenosis. RESULTS: The study included 36 children. Incidence of subglottic stenosis was 11.1%. Children with subglottic stenosis had a higher percentage of COMFORT-B scores between 23 and 30 (undersedated) than those who did not develop subglottic stenosis (15.8% vs. 3.65%, p=0.004). CONCLUSION: Children who developed subglottic stenosis were less sedated than children who did not develop subglottic stenosis.

Health professionals' perceptions about the decision-making process in the care of pediatric patients. / Percepção de profissionais de saúde sobre o processo de tomada de decisão na assistência a pacientes pediátricos.

OBJECTIVE: To evaluate the perceptions of physicians, nurses and nursing technicians of their participation in the decision-making process surrounding life support limitation in terminally ill pediatric patients, with comparisons by professional category. METHODS: A cross-sectional study was conducted in the pediatric intensive care unit of a tertiary public university hospital with the participation of physicians, nurses and nursing technicians. The MacArthur Admission Experience Survey Voice Scale was used to assess and quantify the perceptions of professionals who assisted 17 pediatric patients with life support limitation within 24 hours after the outcome of each patient was determined. All professionals working in the unit (n = 117) who were potentially eligible for the study received a free and informed consent form prior to the occurrence of the cases studied. RESULTS: Study participants included 25/40 (62.5%) physicians, 10/17 (58.8%) nurses and 41/60 (68.3%) nursing technicians, representing 65% of the eligible professionals identified. The questionnaire return rate was higher for physicians than technicians (p = 0.0258). A perceived lack of voice was reported in all three professional categories at varying rates that were lower for physicians than for nurses and nursing technicians (p < 0.00001); there was no difference between the latter (p = 0.7016). In the three professional categories studied, three subscale items were reported. For two of the three statements, there were significant differences between physicians and nurses (p = 0.004) and between physicians and nursing technicians (p = 0.001). For one of the statements, there was no difference among the three professional categories. CONCLUSION: Respondents perceived a lack of voice in the decision-making process at varying rates across the three categories of studied professionals who assisted terminally ill pediatric patients with life support limitation, with physicians expressing lowered rates of perceived coercion.

Incidence and endoscopic characteristics of acute laryngeal lesions in children undergoing endotracheal intubation / Incidência e características endoscópicas de lesões agudas laríngeas em crianças submetidas à intubação endotraqueal

ABSTRACT INTRODUCTION: Acute laryngeal lesions after intubation appear to be precursors of chronic lesions. OBJECTIVE: To describe the incidence and type of acute laryngeal lesions after extubation in a pediatric intensive care unit (PICU). METHODS: A cohort study involving children from birth to <5 years, submitted to intubation for more than 24 h in the PICU of an university hospital. In the first eight hours after extubation, a flexible fiberoptic laryngoscopy (FFL) was performed at the bedside. Those with moderate to severe abnormalities underwent a second examination seven to ten days later. RESULTS: 177 patients were included, with a median age of 2.46 months. The mean intubation time was 8.19 days. Seventy-three (41.2%) patients had moderate or severe alterations at the FFL, with the remaining showing only minor alterations or normal results. During follow-up, 16 children from the group with moderate to severe lesions developed subglottic stenosis. One patient from the normal FFL group had subglottic stenosis, resulting in an incidence of 9.6% of chronic lesions. CONCLUSION: Most children in the study developed mild acute laryngeal lesions caused by endotracheal intubation, which improved in a few days after extubation.

Resumo Introdução: As lesões laríngeas agudas após a intubação parecem ser precursoras das lesões crônicas. Objetivo: Descrever a incidência e o tipo de lesões laríngeas agudas após extubação em Unidade de Terapia Intensiva Pediátrica (UTIP). Método: Estudo de coorte envolvendo crianças de 0 a 5 anos incompletos, com intubação por mais de 24 horas na UTIP de um hospital universitário. Nas primeiras 8 horas após extubação, uma nasofibrolaringoscopia à beira do leito foi realizada. Aqueles com anormalidades moderadas a graves foram submetidos a novo exame entre 7-10 dias após. Resultados: 177 pacientes foram incluídos, com idade mediana de 2,46 meses. O tempo médio de intubação foi de 8,19 dias. Setenta e três (41,2%) pacientes apresentaram alterações moderadas ou graves à laringoscopia, o restante mostrando apenas alterações leves ou exame normal. Durante o acompanhamento, 16 crianças do grupo lesões moderada a grave desenvolveram estenose subglótica. Um paciente do grupo laringoscopia normal teve estenose subglótica, somando-se uma incidência de 9,6% de lesões crônicas. Conclusão: A maioria das crianças do estudo desenvolveu lesões laríngeas agudas leves decorrentes da intubação endotraqueal, com melhora em alguns dias após a extubação.

Percepção de profissionais de saúde sobre o processo de tomada de decisão na assistência a pacientes pediátricos / Health professionals' perceptions about the decision-making process in the care of pediatric patients

RESUMO Objetivo: Avaliar as percepções de médicos, enfermeiros e técnicos de enfermagem sobre sua participação no processo de tomada de decisão de limitação de suporte de vida, em pacientes pediátricos terminais, comparando por categoria profissional. Métodos: Estudo transversal realizado em unidade de terapia intensiva pediátrica de hospital público universitário, terciário, com a participação de médicos, enfermeiros e técnicos de enfermagem. Foi usada a Escala de Voz da MacArthur Admission Experience Survey para avaliar e quantificar a percepção dos profissionais que assistiram 17 pacientes pediátricos em limitação de suporte de vida, nas primeiras 24 horas após o desfecho de cada paciente. Todos os profissionais que atuavam na unidade (n=117), potencialmente elegíveis para a pesquisa, receberam o Termo de Consentimento Livre e Esclarecido previamente à ocorrência dos casos. Resultados: Participaram 25/40 (62,5%) médicos, 10/17 (58,8%) enfermeiros e 41/60 (68,3%) técnicos de enfermagem, representando 65% dos profissionais elegíveis. A taxa de devolução dos questionários pelos médicos foi maior que a dos técnicos (p = 0,0258). Houve registro de percepção de falta de voz nas três categorias profissionais, em taxas variáveis, porém menos percebida pelos médicos do que pelos enfermeiros e técnicos (p < 0,00001); entre estes últimos, não houve diferença (p = 0,7016). Nas três categorias profissionais, foram assinalados os três itens que compõem a subescala. Em duas das três afirmativas, houve diferença significativa entre médicos e enfermeiros (p = 0,004), e entre médicos e técnicos (p = 0,001). Em uma das afirmativas, não houve diferença entre as três categorias profissionais. Conclusão: Houve percepção de falta de voz no processo de tomada de decisão, em taxas variáveis, nas três categorias de profissionais que assistiram pacientes pediátricos terminais em limitação de suporte de vida, sendo os médicos os que expressaram menor percepção de coerção.

ABSTRACT Objective: To evaluate the perceptions of physicians, nurses and nursing technicians of their participation in the decision-making process surrounding life support limitation in terminally ill pediatric patients, with comparisons by professional category. Methods: A cross-sectional study was conducted in the pediatric intensive care unit of a tertiary public university hospital with the participation of physicians, nurses and nursing technicians. The MacArthur Admission Experience Survey Voice Scale was used to assess and quantify the perceptions of professionals who assisted 17 pediatric patients with life support limitation within 24 hours after the outcome of each patient was determined. All professionals working in the unit (n = 117) who were potentially eligible for the study received a free and informed consent form prior to the occurrence of the cases studied. Results: Study participants included 25/40 (62.5%) physicians, 10/17 (58.8%) nurses and 41/60 (68.3%) nursing technicians, representing 65% of the eligible professionals identified. The questionnaire return rate was higher for physicians than technicians (p = 0.0258). A perceived lack of voice was reported in all three professional categories at varying rates that were lower for physicians than for nurses and nursing technicians (p < 0.00001); there was no difference between the latter (p = 0.7016). In the three professional categories studied, three subscale items were reported. For two of the three statements, there were significant differences between physicians and nurses (p = 0.004) and between physicians and nursing technicians (p = 0.001). For one of the statements, there was no difference among the three professional categories. Conclusion: Respondents perceived a lack of voice in the decision-making process at varying rates across the three categories of studied professionals who assisted terminally ill pediatric patients with life support limitation, with physicians expressing lowered rates of perceived coercion.

Characteristics and progression of children with acute viral bronchiolitis subjected to mechanical ventilation.

OBJECTIVE: To analyze the characteristics of children with acute viral bronchiolitis subjected to mechanical ventilation for three consecutive years and to correlate their progression with mechanical ventilation parameters and fluid balance. METHODS: Longitudinal study of a series of infants (< one year old) subjected to mechanical ventilation for acute viral bronchitis from January 2012 to September 2014 in the pediatric intensive care unit. The children's clinical records were reviewed, and their anthropometric data, mechanical ventilation parameters, fluid balance, clinical progression, and major complications were recorded. RESULTS: Sixty-six infants (3.0 ± 2.0 months old and with an average weight of 4.7 ± 1.4kg) were included, of whom 62% were boys; a virus was identified in 86%. The average duration of mechanical ventilation was 6.5 ± 2.9 days, and the average length of stay in the pediatric intensive care unit was 9.1 ± 3.5 days; the mortality rate was 1.5% (1/66). The peak inspiratory pressure remained at 30cmH2O during the first four days of mechanical ventilation and then decreased before extubation (25 cmH2O; p < 0.05). Pneumothorax occurred in 10% of the sample and extubation failure in 9%, which was due to upper airway obstruction in half of the cases. The cumulative fluid balance on mechanical ventilation day four was 402 ± 254mL, which corresponds to an increase of 9.0 ± 5.9% in body weight. Thirty-seven patients (56%) exhibited a weight gain of 10% or more, which was not significantly associated with the ventilation parameters on mechanical ventilation day four, extubation failure, duration of mechanical ventilation or length of stay in the pediatric intensive care unit. CONCLUSION: The rate of mechanical ventilation for acute viral bronchiolitis remains constant, being associated with low mortality, few adverse effects, and positive cumulative fluid balance during the first days. Better fluid control might reduce the duration of mechanical ventilation.

Características e evolução de crianças com bronquiolite viral aguda submetidas à ventilação mecânica / Characteristics and progression of children with acute viral bronchiolitis subjected to mechanical ventilation

RESUMO Objetivo: Analisar as características de crianças com bronquiolite viral aguda submetidas à ventilação mecânica em 3 anos consecutivos, relacionando a evolução com os parâmetros de ventilação mecânica e o balanço hídrico. Métodos: Estudo longitudinal de uma série de casos de lactentes (< 1 ano) submetidos à ventilação mecânica por bronquiolite viral aguda entre janeiro de 2012 e setembro de 2014 na unidade de terapia intensiva pediátrica. Os prontuários foram revisados e foram coletados dados antropométricos e dados referentes à ventilação mecânica, ao balanço hídrico, à evolução e a complicações maiores. Resultados: Incluídos 66 lactentes (3,0 ± 2,0 meses e peso médio de 4,7 ± 1,4kg), sendo 62% do sexo masculino, com etiologia viral identificada em 86%. O tempo médio de ventilação mecânica foi 6,5 ± 2,9 dias, tempo de unidade de terapia intensiva pediátrica de 9,1 ± 3,5 dias, com mortalidade de 1,5% (1/66). O pico de pressão inspiratória médio manteve-se em 30cmH2O nos 4 primeiros dias de ventilação mecânica, reduzindo-se na pré-extubação (25cmH2O; p < 0,05). Pneumotórax ocorreu em 10% e falha de extubação em 9%, sendo a metade por obstrução alta. O balanço hídrico cumulativo no quarto dia de ventilação mecânica foi 402 ± 254mL, correspondendo a um aumento de 9,0 ± 5,9% no peso. Tiveram aumento de 10% ou mais no peso 37 pacientes (56%), sem associação significativa aos parâmetros ventilatórios no 4º dia de ventilação mecânica, falha de extubação ou tempos de ventilação mecânica e unidade de terapia intensiva pediátrica. Conclusão: A taxa de ventilação mecânica na bronquiolite viral aguda tem se mantido constante, apresentando baixa mortalidade, poucos efeitos adversos e associada a balanço hídrico cumulativo positivo nos primeiros dias. Melhor controle hídrico poderia reduzir o tempo de ventilação mecânica.

Incidence and endoscopic characteristics of acute laryngeal lesions in children undergoing endotracheal intubation.

INTRODUCTION: Acute laryngeal lesions after intubation appear to be precursors of chronic lesions. OBJECTIVE: To describe the incidence and type of acute laryngeal lesions after extubation in a pediatric intensive care unit (PICU). METHODS: A cohort study involving children from birth to <5 years, submitted to intubation for more than 24h in the PICU of an university hospital. In the first eight hours after extubation, a flexible fiberoptic laryngoscopy (FFL) was performed at the bedside. Those with moderate to severe abnormalities underwent a second examination seven to ten days later. RESULTS: 177 patients were included, with a median age of 2.46 months. The mean intubation time was 8.19 days. Seventy-three (41.2%) patients had moderate or severe alterations at the FFL, with the remaining showing only minor alterations or normal results. During follow-up, 16 children from the group with moderate to severe lesions developed subglottic stenosis. One patient from the normal FFL group had subglottic stenosis, resulting in an incidence of 9.6% of chronic lesions. CONCLUSION: Most children in the study developed mild acute laryngeal lesions caused by endotracheal intubation, which improved in a few days after extubation.
