Proporção e fatores associados a Apgar menor que 7 no 5º minuto de vida: de 1999 a 2019, o que mudou? / Proportion and factors associated with Apgar less than 7 in the 5th minute of life: from 1999 to 2019, what has changed?

Resumo Apesar da variação entre observadores na avaliação do escore de Apgar, ele permanece um indicador útil das condições gerais do recém-nascido. O presente trabalho é um estudo de corte transversal baseado na população de nascidos vivos no Brasil no ano de 1999 e no biênio 2018-2019. Foram avaliadas todas as declarações de nascidos vivos (DNV) obtidas a partir do banco de dados do Sistema de Informações sobre Nascidos Vivos. As frequências foram comparadas entre os grupos por meio do teste qui-quadrado de Pearson e foi realizada análise de regressão logística multivariada. Adotou-se nível de significância estatística de 0,05. Foram analisadas 9.050.521 DNVs em nossa pesquisa. Constatamos que 2,1% dos recém-nascidos tiveram Apgar de 5º minuto < 7 em 1999, em comparação com 0,9% em 2018-2019. A análise multivariada indicou que gemelidade e gravidez na adolescência deixaram de ser fatores de risco para Apgar de 5º minuto < 7. Entre os fatores de risco, nota-se aumento da prematuridade, baixo peso ao nascer e anomalias congênitas. Observou-se melhoria de marcadores maternos, em especial o aumento do número de consultas pré-natais e escolaridade. Tais achados mostram a importância de acesso e seguimento pré-natal adequado e investimento em melhores condições socioeconômicas como estratégia eficaz para redução de morbimortalidade neonatal.

Abstract Although variation between observers in the assessment of the Apgar score, it remains a useful indicator of the general conditions of the newborn. This is a cross-sectional study based on population of live births in Brazil in 1999 and biennium 2018-2019. All declarations of live births (DNV) obtained from the Live Births System database were accessed. Frequencies were compared between groups using Pearson's chi-square test and multivariate logistic regression analysis was performed. A statistical significance level of 0.05 was considered. We included 9.050.521 DNVs in our research. We found that 2,1% of newborns had 5th minute Apgar < 7 in 1999 compared with 0,9% in 2018-2019. Multivariate analysis shows that twins and teenage pregnancy are no longer risk factors. Among risk factors, we observed an increase in prematurity, low birth weight and congenital anomalies. An improvement in maternal markers was observed, especially increase in the number of prenatal consultations and schooling. Such findings demonstrate the importance access and adequate prenatal care and improved socioeconomic conditions as effective strategy to reduce neonatal morbidity and mortality.

Impacto de uma intervenção educativa no manejo da hipotermia terapêutica neonatal: estudo quase experimental / Impact of an educational intervention in the management of neonatal therapeutic hypothermia: a quasi-experimental study

Introdução: A hipotermia terapêutica é o tratamento indicado para encefalopatia moderada a grave em recém-nascidos. A terapia requer uma equipe de enfermagem capacitada e integrada, visando um cuidado qualificado, efetivo e seguro. Modelos teóricos têm sido desenvolvidos para auxiliar a incorporação de evidências científicas à prática dos enfermeiros, representando um desafio na área da saúde. A implementação de uma intervenção educativa, guiada pela estrutura i-PARIHS (Estrutura Integrada de Promoção da Ação na Implementação de Pesquisa em Serviços de Saúde), poderá preencher a lacuna entre a teoria e a prática, beneficiando a assistência e tornando os sujeitos ativos no manejo do recém-nascido em hipotermia terapêutica. Objetivo geral: avaliar o impacto de uma intervenção educativa, guiada pelo referencial teórico i-PARIHS, sobre o manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica na unidade intensiva neonatal no conhecimento, atitudes e práticas de enfermeiros. Objetivos específicos: analisar o conhecimento, atitude e prática dos enfermeiros sobre o manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica pré e pós-intervenção educativa; identificar as barreiras e facilitadores percebidos pelos enfermeiros sobre o manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica na unidade intensiva neonatal; implementar uma intervenção educativa, guiada pelo referencial i-PARIHS, para melhorar o conhecimento, a atitude e a prática dos enfermeiros sobre o manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica na unidade intensiva neonatal; comparar o conhecimento, atitude e prática dos enfermeiros após a intervenção educativa e os indicadores quanto ao manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica. Método: trata-se de um estudo de intervenção, do tipo quase-experimental, realizado com 29 enfermeiros de uma unidade intensiva neonatal, referência no Rio de Janeiro. O desfecho principal: conhecimento, atitudes e práticas dos enfermeiros no manejo do recém-nascido com asfixia perinatal em hipotermia terapêutica na unidade intensiva neonatal A intervenção compreendeu três fases: pré-intervenção - intervenção educativa- pós-intervenção. A intervenção educativa contou com cinco encontros: "Asfixia Perinatal x Hipotermia Terapêutica", "Controle da temperatura", "Cuidados de enfermagem na HT: avaliação de dor", "Monitoramento neurológico" e "Cuidado Centrado na Família". Para a análise estatística utilizou-se de análise descritiva e aplicação dos testes Wilcoxon-Mann-Whitney e Mc Nemar, sendo o nível de significância adotado de 0,05. Resultados: a análise dos resultados do pré e pós-teste demonstrou um incremento no escore de acertos das questões sobre conhecimento, atitude e prática dos enfermeiros no manejo do recém-nascido submetido à hipotermia terapêutica na unidade intensiva neonatal, apresentando significância estatística para a maioria dos itens. Para a inovação foram construídos lembretes, fluxo de admissão para recém-nascido da instituição e uma cartilha para os pais como produto da intervenção com os enfermeiros. Conclusão: O resultado das auditorias realizadas, após a implementação das evidências, constatou uma transformação positiva da prática dos enfermeiros. A utilização da estrutura i-PARIHS evidenciou a necessidade e o valor de investir no engajamento das partes interessadas, na avaliação colaborativa do contexto e na cocriação de inovação usando facilitação qualificada. A intervenção educativa, guiada pela estrutura i-PARIHS, mostrou ter impacto no manejo do recém-nascido submetido à hipotermia terapêutica por enfermeiros.

Introduction: Therapeutic hypothermia is the currently indicated treatment for moderate to severe encephalopathy in newborns. Therapy requires a trained and integrated nursing team, aiming at qualified, effective and safe care. Theoretical models have been developed to help the incorporation of scientific evidence into nurses' practice, representing a challenge in the health area. The implementation of an educational intervention, guided by the i-PARIHS (Integrated Promoting Action on Research Implementation in Health Services Framework) framework, can fill the gap between theory and professional practice, benefiting care and making subjects active in the management of newborns with therapeutic hypothermia. General objective: to evaluate the impact of an educational intervention guided by the theoretical framework i-PARIHS, on the management of newborns with perinatal asphyxia in therapeutic hypothermia in the neonatal intensive care unit on the knowledge, attitudes and practices of nurses. Specific objectives: to analyze the knowledge, attitude and practice of nurses on the management of newborns with perinatal asphyxia in pre- and post-educational therapeutic hypothermia; to identify barriers and facilitators perceived by nurses on the management of newborns with perinatal asphyxia in therapeutic hypothermia in the neonatal intensive care unit; implement an educational intervention, guided by the i-PARIHS framework, to improve nurses' knowledge, attitude and practice on the management of newborns with perinatal asphyxia in therapeutic hypothermia in the neonatal intensive care unit and compare the knowledge, attitude and practice of nurses after the participatory educational intervention program and indicators regarding the management of newborns with perinatal asphyxia in therapeutic hypothermia. Method: this is a quasi-experimental intervention study carried out with 29 nurses from a neonatal intensive care unit, a reference in Rio de Janeiro. The main outcome: knowledge, attitudes and practices of nurses in the management of newborns with perinatal asphyxia in therapeutic hypothermia in the neonatal intensive unit The intervention comprised three phases: pre-intervention - educational intervention - post-intervention. The educational intervention had five meetings: "Perinatal Asphyxia x Therapeutic Hypothermia", "Temperature control", "Nursing care in HT: pain assessment", "Neurological monitoring" and "Family-Centered Care". For the statistical analysis, descriptive analysis and application of the Wilcoxon-Mann-Whitney and Mc Nemar tests were used, with the adopted significance level of 0.05. Results: the analysis of pre- and post-test results showed an increase in the correct score of questions about nurses' knowledge and practices in the management of newborns submitted to therapeutic hypothermia in the neonatal intensive care unit, showing statistical significance for most items. For innovation, reminders, admission flow for newborns at the institution and a booklet for parents were created as a product of the intervention with nurses. Conclusion: The result of the audits carried out, after the implementation of the evidence, found a positive transformation of the nurses' practice. Using the i-PARIHS framework highlighted the need and value of investing in stakeholder engagement, collaborative context assessment, and co-creation of innovation using qualified facilitation. The educational intervention guided by the i-PARIHS framework was shown to have an impact on the management of newborns with perinatal asphyxia in therapeutic hypothermia by nurses.

Retos en la aplicación de la hipotermia terapéutica no servo-controlada durante el transporte neonatal en Cataluña / Challenges in the application of non-servocontrolled therapeutic hypothermia during neonatal transport in Catalonia

Introducción: La hipotermia terapéutica (HTT) es el único tratamiento que ha demostrado aumentar la posibilidad de supervivencia libre de secuelas en los recién nacidos (RNs) afectos de encefalopatía hipóxico-isquémica (EHI), recomendándose iniciarla lo antes posible. Lo más frecuente es que los pacientes tributarios de HTT no nazcan en los centros de referencia (CR) .requiriendo ser transportados. Métodos: Estudio observacional descriptivo prospectivo de RNs con EHI moderada-grave trasladados en hipotermia terapéutica no servo-controlada por los dos equipos de transporte neonatal y pediátrico terrestres de Cataluña (abril 2018-noviembre 2019). Resultados: 51 pacientes. Mediana de tiempo de estabilización 68 minutos (p25-75, 45 – 85min), traslado 30 minutos (p25-75, 15 – 45min). Media de edad a la llegada al CR 4 horas y 18 minutos (DE 96min). Medidas terapéuticas adoptadas: apagar la incubadora 43 (84,3%), bolsas de hielo 11 (21,6%) y ambas 11 (21,5%) pacientes. Se consiguió la temperatura rectal (TR) diana en 19 (37,3%) pacientes. No hubo diferencias en el sobre-enfriamiento según las medidas usadas para la aplicación de la HTT no servo-controlada (HTTnc). La duración del traslado no se relacionó con diferencias en la estabilización de la temperatura ni en la consecución de la temperatura objetivo.Conclusiones: La monitorización de la TR en el centro emisor es un pilar fundamental en la estabilización del paciente y la aplicación de la HTTnc. Existe una clara área de mejora en la eficacia de la HTTnc durante el transporte. La HTT servo-controlada sería una opción para poder ofrecer las mismas posibilidades terapéuticas a los RNs extramuros de los CR. (AU)

Introduction: Therapeutic hypothermia (TH) improves survival and neurological prognosis in hypoxic-ischemic encephalopathic (HIE) babies, being better the sooner TH is implemented. HIE babies are born more frequently in a non-cooling centre and need to be referred.Methods: Prospective-observational study (April 18–November 19). Newborns (≥34 weeks of gestational age (GA) and >1800g) with moderate/severe HIE on non-servocontrolled therapeutic hypothermia by the two neonatal transport teams in Catalonia.Results: 51 newborns. The median stabilisation and transport time were 68min (p25–75, 45–85min) and 30min (p25–75, 15–45min), respectively. The mean age at arrival at the receiving unit was 4h and 18min (SD 96.6). The incubator was set off in 43 (84%), iced-packs 11 (21.5%) and both (11, 21.5%). Target temperature was reached in 19 (37.3%) babies. There was no differences in the overcooling in relation to the measures applied. The transport duration was not related with temperature stabilisation or target temperature reachiness.Conclusions: Rectal temperature monitorisation is compulsory for the stabilisation and the application of non-servocontrolled hypothermia during transport. There is still time for improving in the administration of this treatment during transport. Servo-controlled hypothermia would be a better alternative to improve the management of HIE babies. (AU)

Valoración del recién nacido. Correlación del test de Apgar con la gasometría arterial al nacimiento / Assessment of the newborn. Correlation of the Apgar test with arterial blood gas at birth

Objetivo: Evaluar la correlación entre las puntuaciones del test de Apgar y los valores de la gasometría arterial al nacimiento. Metodología: Estudio descriptivo transversal de prevalencia realizado en el Hospital Universitario Rafael Méndez de Lorca (España). Los datos se obtuvieron del registro informático de datos clínicos, analizando como variable dependiente las puntuaciones del test de Apgar al minuto de vida, y como variables independientes el pH, la presión parcial de dióxido de carbono y el déficit de base, recogidos mediante gasometría de la arteria umbilical al nacimiento. El análisis estadístico adoptó un nivel de significación estadística de p <0,05 mediante la aplicación de pruebas paramétricas, como el coeficiente de correlación de Pearson, la t de Student para muestras independientes y la χ2 . Resultados: La muestra fue de 312 neonatos. Se observa una correlación significativa entre las puntuaciones del test de Apgar patológicas y la acidosis fetal (p= 0,006; odds ratio [OR]= 2,555), la hipercapnia (p= 0,004; OR= 2,675), el déficit de bases (p= 0,001; OR= 4,758) y la acidosis metabólica (p= 0,018; OR= 3,556) al nacimiento. Conclusiones: Se puede establecer una correlación entre el test de Apgar al minuto de vida y la gasometría arterial al nacimiento. Se observa una subestimación profesional en las puntuaciones de las acidosis respiratorias. (AU)

Objective: To evaluate the degree of correlation between the Apgar test scores and the arterial blood gas values at birth. Methodology: Observational, analytical, retrospective and prevalence study carried out at the Hospital Universitario Rafael Méndez (Spain) on a sample of 312 neonates. The data were obtained from the computerized registry of clinical data, analyzing the Apgar test scores at one minute of life as a dependent variable, and pH, pCO2 and base deficits collected by means of umbilical artery blood gases at birth as independent variables. Statistical analysis adopted a significance level of p <0.05 through the application of parametric tests such as Pearson's correlation coefficient, Student’s t-test for independent samples and χ2 . Results: A significant correlation is observed between pathological Apgar test scores and fetal acidosis (p= 0.006; Odds ratio [OR]= 2.555), hypercapnia (p= 0.004; OR= 2.675), base deficit (p= 0.001; OR= 4.758) and metabolic acidosis (p= 0.018; OR= 3.556) at birth. Conclusions: A correlation can be established between the Apgar test at minute of life and arterial blood gas at birth, observing a professional underestimation in the scores of respiratory acidosis.

Resumen: El síndrome de QT largo adquirido puede ser secundario a la hipotermia, tanto accidental como terapéutica. Es poco el conocimiento sobre el efecto de ésta en la actividad eléctrica cardíaca, sobre todo en recién nacidos, y sus potenciales complicaciones. Se presenta el caso clínico de un recién nacido con diagnóstico de encefalopatía hipóxico isquémica que presenta una prolongación del intervalo QT durante el tratamiento con hipotermia. Se discute la evolución del paciente, que es consistente con lo referido en la literatura sobre el tema: buena evolución, ausencia de arritmias graves o alteraciones hemodinámicas, y normalización del electrocardiograma luego de finalizado el tratamiento.

Summary: Acquired long QT syndrome may be secondary to hypothermia, both accidental and therapeutic. There is not enough knowledge about the effect of hypothermia in cardiac activity and its potential complications, especially in newborns. We present the clinical case of a newborn with a diagnosis of hypoxic ischemic encephalopathy who has a prolonged QT interval during treatment with hypothermia. The evolution of the patient is discussed, which is consistent with what is referred to in the literature on the subject: Good evolution, absence of serious arrhythmias or hemodynamic alterations, and normalization of the ECG after the end of treatment.

Características clínicas y del electroencefalograma de amplitud integrada en recién nacidos con encefalopatía hipóxico-isquémica bajo protocolo de hipotermia corporal total / Clinical and integrated amplitude electroencephalogram characteristics of newborns with hypoxic-ischemic encephalopathy under the protocol of total body hypothermia

RESUMEN La encefalopatía hipóxico-isquémica (EHI) es causa importante de mortalidad y discapacidad neurológica en neonatos. La evidencia sugiere que la terapia de hipotermia es capaz de impactar estos desenlaces. Este estudio se realizó con el objetivo de describir las características clínicas y las ayudas diagnósticas realizadas a recién nacidos con EHI sometidos a terapia de hipotermia corporal total con el uso de criterios preestablecidos de ingreso a la terapia, en una muestra de dos instituciones de la ciudad de Medellín. MÉTODOS: Se realizó un estudio descriptivo en el periodo 2017-2018, incluyendo la totalidad de pacientes con EHI ingresados a terapia de hipotermia. RESULTADOS: Se obtuvieron datos de 256 pacientes, con predominio masculino (182; 71,1%). Se evidenciaron fallas en el registro y subjetividad en la aplicación de los criterios de ingreso al protocolo de hipotermia en ambas instituciones. En 197 pacientes (77 %) no hubo reporte de evento centinela, y el expulsivo prolongado fue considerado por los clínicos un hallazgo significativo a la hora de definir el ingreso a la terapia. Hubo, además, pacientes ingresados que no cumplieron con el criterio de APGAR ≤ 5 a los 10 minutos (n = 136). Los resultados sugieren la necesidad de mejorar la adherencia al protocolo de ingreso a la terapia, pero al mismo tiempo señalan la importancia del concepto del clínico a la hora de abordar cada paciente de manera individual.

SUMMARY Hypoxic-ischemic encephalopathy (HIE) is an important cause of mortality in the neonatal population and neurological disability. The evidence shows that hypothermia therapy is capable of impacting these outcomes. This study was carried out with the objective of describing the clinical characteristics and the diagnostic aids made to newborns with HIE undergoing total body hypothermia therapy and the use of criteria for admission to therapy in a sample of two institutions in the city of Medellin. METHODS: A descriptive retrospective study was conducted, including all patients with HIE admitted to hypothermia therapy during 2017 and 2018. RESULTS: The data of 256 patients (males 182; 71.1 %) were obtained. There were flaws in the registry and subjectivity in the application of the entry criteria to the hypothermia protocol in both institutions. In 197 (77 %) patients there was no report of sentinel event and the prolonged labour was considered by the clinicians as a significant finding when defining the entrance to the therapy. There were also admitted patients who did not meet the criterion of APGAR ≤ 5 at 10 minutes (n = 136). The results suggest the need to improve adherence to the protocol for admission to therapy; but at the same time, it points out the importance of the clinician's concept when dealing with each patient individually.

Conclusión: De los niños que presentaron asfixia neonatal las características más representativas fue la edad de la madre, seguidamente el nivel educativo de las mismas y ser solteras. La mayoría de los recién nacidos pertenecen al género masculino, con un peso dentro de lo normal. La estadía hospitalaria oscila entre 5 a 10 días, todos ellos recibiendo terapias a diario. Del total de las complicaciones que se identifican, resulta predominante la del Síndrome de Distrés Respiratorio (SDR)

Selective head cooling and whole body cooling as neuroprotective agents in severe perinatal asphyxia

SUMMARY INTRODUCTION The possibility that hypothermia has a therapeutic role during or after resuscitation from severe perinatal asphyxia has been a longstanding focus of research. Studies designed around this fact have shown that moderate cerebral hypothermia, initiated as early as possible, has been associated with potent, long-lasting neuroprotection in perinatal patients. OBJECTIVES To review the benefits of hypothermia in improving cellular function, based on the cellular characteristics of hypoxic-ischemic cerebral injury and compare the results of two different methods of cooling the brain parenchyma. METHODS Medline, Lilacs, Scielo, and PubMed were searched for articles registered between 1990 and 2019 in Portuguese and English, focused on trials comparing the safety and effectiveness of total body cooling with selective head cooling with HIE. RESULTS We found that full-body cooling provides homogenous cooling to all brain structures, including the peripheral and central regions of the brain. Selective head cooling provides a more extensive cooling to the cortical region of the brain than to the central structures. CONCLUSIONS Both methods demonstrated to have neuroprotective properties, although full-body cooling provides a broader area of protection. Recently, head cooling combined with some body cooling has been applied, which is the most promising approach. The challenge for the future is to find ways of improving the effectiveness of the treatment.

RESUMO INTRODUÇÃO A possibilidade de a hipotermia ter um papel terapêutico durante ou após a reanimação da asfixia perinatal grave tem sido um foco de pesquisa de longa data. Estudos desenhados em torno desse fato mostraram que a hipotermia cerebral moderada, iniciada o mais cedo possível, tem sido associada à neuroproteção potente e duradoura em espécies perinatais. OBJETIVOS Resumidamente, analisar os benefícios da hipotermia na melhoria da função celular, com base nas características celulares da lesão cerebral hipóxico-isquêmica e comparar os resultados de dois métodos diferentes de resfriamento do parênquima cerebral. MATERIAL E MÉTODOS Medline, Lilacs, SciELO e PubMed foram pesquisados para artigos registrados entre 1990 e 2019 nos idiomas português e inglês, com foco em estudos comparando segurança e eficácia do resfriamento corporal total com o resfriamento seletivo da cabeça com EHI. RESULTADOS Descobrimos que o resfriamento de corpo inteiro fornece resfriamento homogêneo para todas as estruturas cerebrais, incluindo as regiões periférica e central do cérebro. O resfriamento seletivo da cabeça fornece um resfriamento mais amplo para a região cortical do cérebro do que para as estruturas centrais. CONCLUSÕES Ambos os métodos demonstraram ter propriedades neuroprotetoras, embora o resfriamento de corpo inteiro forneça uma área mais ampla de proteção. Recentemente, o resfriamento da cabeça combinado com algum resfriamento corporal foi aplicado e essa é a maneira mais promissora. O desafio para o futuro é encontrar formas de melhorar a eficácia do tratamento.

Non-clinical performance and acceptability of a small portable respiratory stimulator device for basic neonatal resuscitation, tested by health personnel / Desempeño no clínico y aceptabilidad de un estimulador respiratorio portátil para reanimación neonatal básica, evaluado en personal de salud

Introducción: La reanimación neonatal demanda dispositivos para apoyo respiratorio que no siempre se encuentran en áreas rurales. Se requieren dispositivos innovadores y el prototipado rápido permite generarlos usando diseños e impresoras tridimensionales (3D). Objetivo: Evaluar el desempeño no clínico y la aceptabilidad por el personal de salud de un dispositivo respiratorio neonatal producido mediante prototipado rápido. Métodos: Estudio observacional, descriptivo, de prueba de concepto desarrollado en dos etapas. Etapa 1: Fabricación del dispositivo con prototipado rápido en impresoras y escáneres tridimensionales (3D). Etapa 2: Demostración del dispositivo durante programas de capacitación en reanimación neonatal para personal de salud en tres regiones del Perú (Tarapoto, Huánuco y Ayacucho). En ambas etapas se evaluó el desempeño del dispositivo conectado a un analizador de flujo de gases. Se administró una encuesta a los trabajadores de salud de Tarapoto y Ayacucho para conocer su aceptabilidad. Resultados: El prototipo desarrollado tiene forma de T con dos fuelles laterales que al presionarse con una sola mano, proyectan aire por el centro hacia un adaptador facial. El uso del prototipo en laboratorio generó un flujo de aire promedio de 4,8 Lt/min (DE ± 1,7) y una presión promedio de 5,9 cm H2O (DE ± 1,4). Este dispositivo fue considerado como "de uso muy simple" en una encuesta de aceptabilidad donde participaron 39 enfermeras y 11 médicos en zonas alejadas de la capital del Perú. Conclusiones: El prototipo evaluado fue aceptado por el personal y tuvo un desempeño capaz de generar un estímulo de la respiración espontánea al nacer.

Introduction: Neonatal resuscitation demands equipment for respiratory support not always available in rural areas. Innovative devices are required, and rapid prototyping allows to generate them using three-dimensional (3D) designs and printers. Objective: To evaluate the non-clinical performance and the acceptability by health personnel of a neonatal respiratory device produced by rapid prototyping. Methods: Observational study, descriptive, of proof of concept developed in two steps. Step 1: Manufacture of the device with rapid prototyping in three-dimensional (3D) scanners and printers. Step 2: Demonstration of the invention during training programs in neonatal resuscitation for health personnel in three regions of Peru (Tarapoto, Huánuco and Ayacucho). In both steps, we evaluated the performance of the device connected to a gas flow analyser. A survey was administered to the health workers of Tarapoto and Ayacucho to know their acceptability. Results: The developed prototype is T-shaped with two side bellows that, when pressed with one hand, project air through the centre towards a facial adapter. The use of the prototype in the laboratory generated an average air flow of 4.8 Lt /min (SD ± 1.7) and an average pressure of 5.9 cm H2O (SD ± 1.4). This device was considered to be "very simple to use" in an acceptability survey involving 39 nurses and 11 doctors in remote areas of the capital of Peru. Conclusions: The evaluated prototype is acceptable by the staff and has a performance capable of generating spontaneous breathing at birth.

Perinatal Asphyxia: Factors Associated with Noncompliance in the specialized Outpatient Treatment / Asfixia Perinatal: Fatores Associados à não-Adesão no Tratamento Ambulatorial Especializado

Perinatal asphyxia is a leading cause of preventable brain injury. Between four and nine million newborns develop birth asphyxia. It is estimated that 1.2 million evolve to death and at least the same number develops important disabling neurological sequels. These children need to be accompanied by experts, especially in the first year of life. The continuity of care after hospital discharge should be guaranteed so that there is follow-up care to those who are at increased risk of morbidity and mortality. To identify factors associated with dropout of outpatient specialized treatment of children diagnosed with perinatal asphyxia. The study was conducted in neonatal care clinic specializing in a reference hospital for high-risk births in the state of Sergipe. 98 children with perinatal asphyxia discharged from the Neonatal Intensive Care Unit of this hospital participated in the study. Results: the children who were followed up were between two months to two years old, and predominantly male 69. Ten children were discharged at age 24 months and had important neurological sequels. Thirty-one children were discharged aged 10 to 20 months without deficit and 35 remained in regular monitoring. There was a record of 22 cases of noncompliance, before the sixth medical consultation. Among the reasons for the doctor following the abandonment of the follow-up service, there were more reasons regarding the absence of symptoms (and distance from home). The absence of symptoms and distance from the capital were associated with the abandonment of outpatient treatment of anoxic children. Outpatient services should be organized to minimize the follow-up abandon situations. (AU)

Asfixia perinatal é uma das principais causas de lesão cerebral evitável. Cerca de quatro a nove milhões de recém-nascidos desenvolvem asfixia ao nascer. Estima-se que 1,2 milhão evoluem para óbito e desenvolvem sequelas neurológicas incapacitantes. Essas crianças precisam ser acompanhadas por especialistas, principalmente no primeiro ano de vida. A continuidade da assistência após a alta hospitalar deve ser garantida para que haja seguimento do cuidado aos que apresentam maior risco de morbimortalidade. Identificar fatores associados ao abandono do tratamento ambulatorial especializado de crianças diagnosticadas com asfixia perinatal. Estudo desenvolvido no ambulatório de assistência neonatal de uma maternidade referência para partos de alto risco no estado de Sergipe. Participaram do estudo 98 crianças anoxiadas egressas da Unidade de Terapia Intensiva Neonatal dessa maternidade. As crianças acompanhadas tinham entre dois meses a dois anos, predominantemente do sexo masculino 69. Dez crianças receberam alta por idade aos 24 meses, apresentando sequelas neurológicas importantes. Trinta e uma crianças receberam alta entre 10 a 20 meses sem déficit e 35 mantiveram-se em acompanhamento regular. Houve o registro de 22 casos de abandono do tratamento, antes da sexta consulta médica. Entre os motivos para o abandono do seguimento no serviço de follow-up, predominaram a ausência de sintomas e a distância do domicílio. A ausência de sintomas e a distância da capital estiveram associadas ao abandono de tratamento ambulatorial de crianças anoxiadas. Os serviços ambulatoriais devem estar organizados para minimizar situações de abandono do seguimento. (AU)

Material y métodos: estudio analítico, que se incluyeron 43 infantes con el antecedente de Encefalopatía Hipóxico-Isquémica que contaban con ecografía transfontanelar tomada en los primeros 7 días de vida, de quiénes se recolectó información mediante historias clínicas y entrevistas. Se evaluó el desarrollo motor grueso a los 2 años de edad mediante el test de "Sistema de Evaluación de la Función Motriz Gruesa". Resultados: De los 43 participantes, 29 (65,12%) presentaron alteraciones ecográficas y 14 (32,56%), tuvieron alteraciones motoras. De los 14 participantes que tuvieron alteración de la función motriz gruesa, la hemorragia intraventricular y el edema cerebral fueron las más frecuentes, afectando cada una a 6 infantes (42,9%). La relación entre ambas variables (hallazgos ecográficos y alteraciones motoras gruesas) fue significativamente estadística (IC 95%, p<0,05). Conclusión: Las alteraciones en la ecografía transfontanelar son factor pronóstico para déficit en el desarrollo motor grueso durante los 2 primeros años de vida en neonatos a término con diagnóstico de Encefalopatía Hipóxico Isquémica.(AU)

Objetive: Determine if the alterations in the transfontanelar ultrasound is a prognostic factor for motor development alterations during the first 2 years of life in term infants diagnosed with Hypoxic-Ischemic Encephalopathy, seen at the Las Mercedes Regional Hospital and the Almanzor Aguinaga National Hospital Asenjo, during the period 2015-2017. Material and methods: Analytical study, which included 43 infants with a history of Hypoxic-Ischemic Encephalopathy who had transfontanel ultrasound taken in the first 7 days of life, from whom information was collected through clinical histories and interviews. The gross motor development at 2 years of age was evaluated by means of the "Thick Motor Function Assessment System" test. Results: Of the 43 participants, 29 (65.12%) presented ultrasonographic alterations and 14 (32.56%) had motor alterations. Of the 14 participants who had impaired gross motor function, intraventricular hemorrhage and cerebral edema were the most frequent, each affecting 6 infants (42.9%). The relationship between both variables (echographic findings and gross motor alterations) was statistically significant (95% CI, p <0.05). Conclusion: Alterations in transfontanel ultrasound are a prognostic factor for deficit in gross motor development during the first 2 years of life in term neonates with a diagnosis of Ischemic Hypoxic Encephalopathy.(AU)

Indicadores de calidad de la atención a neonatos con patologías seleccionadas: estudio piloto / Quality care indicators for neonates with selected pathologies: pilot study

Resumen: Objetivo: Desarrollar y pilotar indicadores de calidad de la atención a neonatos con padecimientos relevantes en México (prematuridad, sepsis neonatal, asfixia perinatal e hipoxia intrauterina). Material y métodos: Se construyeron indicadores propios a partir de recomendaciones clave de las guías de práctica clínica nacionales e indicadores encontrados en repositorios internacionales. Previa búsqueda, selección y priorización, los indicadores fueron pilotados en dos hospitales. Se analizó la factibilidad de medición, fiabilidad (índice kappa) y utilidad para detectar problemas de calidad. Resultados: Se seleccionaron y pilotaron 23 indicadores; 12 eran compuestos. Del total, nueve fueron factibles y fiables. La calidad de la información en los hospitales fue diversa y frecuentemente deficiente, limitando tanto la factibilidad como la fiabilidad de los indicadores. Los niveles de cumplimiento identificaron oportunidades de mejora. Conclusiones: Se propone un set de nueve indicadores válidos, factibles, fiables y útiles para la monitorización de la calidad en la atención a neonatos patológicos.

Early neonatal deaths associated with perinatal asphyxia in infants ≥2500g in Brazil / Óbitos neonatais precoces associados à asfixia perinatal em neonatos ≥2500g no Brasil

Abstract Objective: To assess the annual burden of early neonatal deaths associated with perinatal asphyxia in infants weighing ≥2500 g in Brazil from 2005 to 2010. Methods: The population study enrolled all live births of infants with birth weight ≥2500 g and without malformations who died up to six days after birth with perinatal asphyxia, defined as intrauterine hypoxia, asphyxia at birth, or meconium aspiration syndrome. The cause of death was written in any field of the death certificate, according to International Classification of Diseases,10th Revision (P20.0, P21.0, and P24.0). An active search was performed in 27 Brazilian federative units. The chi-squared test for trend was applied to analyze early neonatal mortality ratios associated with perinatal asphyxia by study year. Results: A total of 10,675 infants weighing ≥2500 g without malformations died within six days after birth with perinatal asphyxia. Deaths occurred in the first 24 h after birth in 71% of the infants. Meconium aspiration syndrome was reported in 4076 (38%) of these deaths. The asphyxia-specific early neonatal mortality ratio decreased from 0.81 in 2005 to 0.65 per 1000 live births in 2010 in Brazil (p < 0.001); the meconium aspiration syndrome-specific early neonatal mortality ratio remained between 0.20 and 0.29 per 1000 live births during the study period. Conclusions: Despite the decreasing rates in Brazil from 2005 to 2010, early neonatal mortality rates associated with perinatal asphyxia in infants in the better spectrum of birth weight and without congenital malformations are still high, and meconium aspiration syndrome plays a major role.

Resumo Objetivo: Avaliar a taxa anual de óbitos neonatais precoces associados à asfixia perinatal em neonatos de peso ≥ 2.500 g no Brasil de 2005 a 2010. Métodos: A população do estudo envolveu todos os nascidos vivos de neonatos com peso ao nascer ≥ 2.500 g e sem malformações que morreram até seis dias após o nascimento por asfixia perinatal, definida como hipóxia intrauterina, asfixia no nascimento ou síndrome de aspiração de mecônio. A causa do óbito foi escrita em qualquer linha do atestado de óbito, de acordo com a Classificação Internacional de Doenças, 10a Revisão (P20.0, P21.0 e P24.0). Foi feita uma pesquisa ativa em 27 unidades federativas brasileiras. O teste qui-quadrado de tendência foi aplicado para analisar os índices de mortalidade neonatal associados a asfixia perinatal até o ano do estudo. Resultados: Morreram 10.675 neonatos com peso ≥ 2.500 g sem malformações até 0-6 dias após o nascimento por asfixia perinatal. Os óbitos ocorreram nas primeiras 24 horas após o nascimento em 71% dos neonatos. A síndrome de aspiração de mecônio foi relatada em 4.076 (38%) dos óbitos. O índice de mortalidade neonatal precoce relacionada à asfixia caiu de 0,81 em 2005 para 0,65 por 1.000 nascidos vivos em 2010 no Brasil (p < 0,001); o índice de mortalidade neonatal precoce relacionada a síndrome de aspiração de mecônio permaneceu entre 0,20-0,29 por 1.000 nascidos vivos durante o período do estudo. Conclusões: Apesar da redução nas taxas no Brasil de 2005 a 2010, as taxas de mortalidade neonatal precoce associadas à asfixia perinatal em neonatos no melhor espectro de peso ao nascer e sem malformações congênitas ainda são altas e a síndrome de aspiração de mecônio desempenha um importante papel.
