RESUMO

INTRODUCTION: Hypoxic-ischaemic encephalopathy is a clinical syndrome of neurological dysfunction that occurs immediately after birth following an episode of perinatal asphyxia. We conducted a scoping review to assess the methodological quality of clinical practice guidelines that address this condition. METHODOLOGY: We conducted the evaluation using the AGREE II tool. High methodological quality was defined as a score greater than 70% in every domain. RESULTS: The analysis included three clinical practice guidelines; the highest scores were in the scope and purpose domain (84.26%; SD, 14.25%) and the clarity of presentation domain (84.26%; SD, 17.86%), while the lowest score corresponded to the applicability domain (62.50%; SD, 36.62%). Two guidelines were classified as high quality and one guideline as low-quality. CONCLUSIONS: Two of the assessed guidelines were classified as being of high quality; however, the analysis identified shortcomings in the applicability domain, in addition to methodological variation between guidelines developed in middle- or low-income countries versus high-income countries. Efforts are needed to make high-quality guidelines available to approach the management of hypoxic-ischaemic encephalopathy in newborns.

RESUMO

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.

RESUMO

Background and objectives: In low- and middle-income countries, the leading cause of neonatal mortality is perinatal asphyxia. Training in neonatal resuscitation has been shown to decrease this cause of mortality. The program "Helping Babies Breathe" (HBB) is a program to teach basic neonatal resuscitation focused on countries and areas with limited economic resources. The aim of the study was to determine the effect of the implementation of the HBB program on newborn outcomes: mortality and morbidity. Material and Methods: A systematic review was carried out on observational studies and clinical trials that reported the effect of the implementation in low- and middle-income countries of the HBB program on neonatal mortality and morbidity. We carried out a meta-analysis of the extracted data. Random-effect models were used to evaluate heterogeneity, using the Cochrane Q and I2 tests, and stratified analyses were performed by age and type of outcome to determine the sources of heterogeneity. Results: Eleven studies were identified. The implementation of the program includes educational strategies focused on the training of doctors, nurses, midwives, and students of health professions. The poled results showed a decrease in overall mortality (OR 0.67; 95% CI 0.57, 0.80), intrapartum stillbirth mortality (OR 0.62; 95% CI 0.51, 0.75), and first-day mortality (OR 0.70; 95% IC 0.64, 0.77). High heterogeneity was found, which was partly explained by differences in the gestational age of the participants. Conclusions: The implementation of the program HBB in low- and medium-income countries has a significant impact on reducing early neonatal mortality.

RESUMO

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.

RESUMO

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.

Conclusions: The quality of care for newborns in hospitals is heterogeneous and poor. Indicators are proposed to monitor improvement initiatives.

RESUMO

BACKGROUND: The cardiac troponin I (cTnI), creatine phospokinase (CPK), and creatine kinase- myocardial band (CK-MB) are cardiac biomarkers used in newborns with asphyxia. OBJECTIVE: To analyze the relationship between cTnI, CPK and CPK-MB levels with clinical and biochemical diagnostic criteria for neonatal asphyxia. METHODS: Analytical cross-sectional study in neonates with at least one diagnostic criterion of asphyxia. Relationship among cTnI and CPK-MB levels at birth, serum levels of CPK and CPK-MB determined 24 hours after delivery, with metabolic acidosis, Apgar test at 5 minutes with scores of 0-3, neurological alterations and/or multiple organ failure were analyzed. RESULTS: Thirty-four neonates, 73.5% born by cesarean section, 71% term neonates with a mean weight of 3,096 ± 453g, 2,275 ± 509g for preterm, and a mean of 7.77 ± 1.481 and 7.03 ± 1.705 5-minute Apgar score, respectively. 17.6% of the neonates reported a pH value < 7.20, 58% a base deficit of 12 mmol/L, 5.8% obtained a 5-minute Apgar score < 3, and 38.23% had neurological alterations and/or multiple organ dysfunction syndrome. All patients reported cTnI within the normal reference range. CPK and CPK-MB values, 24 hours after delivery, were elevated in 29% of the cases with one or two diagnostic criteria for neonatal asphyxia. The percentage of CPK-MB was associated with gestational age. CONCLUSIONS: cTnI values were normal in suspected cases of neonatal asphyxia, whereas CPK and CPK MB can elevate in these population, principally in preterm newborns. Biochemical markers were not associated with any clinical parameter.

INTRODUCCIÓN: La troponina I (cTnI), la creatina-fosfocinasa (CPK) y la creatina-fosfocinasa-MB (CPK-MB) son biomarcadores cardiacos usados en neonatos con asfixia. OBJETIVO: Analizar la relación entre las concentraciones de cTnI, CPK y CPK-MB con los criterios diagnósticos clínicos y bioquímicos de asfixia neonatal. MÉTODOS: Estudio analítico transversal en neonatos con al menos un criterio diagnóstico de asfixia. Se analizó la relación entre los niveles de cTnI y CPK-MB al nacimiento, niveles séricos de CPK y CPK-MB determinados 24 horas después del parto, con acidosis metabólica, prueba de Apgar a los 5 minutos con puntajes de 0-3, alteraciones neurológicas y/o falla orgánica múltiple. RESULTADOS: De 34 recién nacidos, el 73.5% nacieron vía cesárea, el 71% eran a término con un peso promedio de 3,096 ± 453 g, en los prematuros el peso fue de 2,275 ± 509 g, y la puntuación de Apgar a los 5 minutos fue de 7.77 ± 1.481 y 7.03 ± 1.705, respectivamente. El 17.6% de los neonatos tuvieron un pH < 7.20, el 58% un déficit de base < 12 mmol/l, el 5.8% Apgar < 3 a los 5 minutos y el 38.23% alteraciones neurológicas o falla orgánica múltiple. El 100% de los recién nacidos tuvieron unos valores de cTnI normales. La CPK y la CPK-MB a las 24 horas se encontraron alteradas en un 29% con uno o dos criterios de asfixia. El porcentaje de CPK-MB se asoció con la edad gestacional. CONCLUSIONES: La cTnI fue normal en los neonatos con sospecha de asfixia, pero no así la CPK y la CPK-MB, que pueden elevarse en estos pacientes, principalmente en los nacidos pretérmino. Los marcadores bioquímicos no se asociaron con ninguno de los parámetros clínicos.

RESUMO

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.

RESUMO

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.

RESUMO

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)

RESUMO

Introducción: La depresión neonatal es una de las causas más frecuentes de ingreso de recién nacidos a unidades especializadas de atención neonatal. La asfixia perinatal es una de las causas de bajo puntaje de Apgar, siendo uno de los criterios clínicos para su diagnóstico. Los principales factores de riesgo vinculados con bajos puntajes de Apgar pueden ser maternos (edad, patologías obstétricas, nivel socioeconómico, adicciones, etc.), del trabajo de parto y parto o, alteraciones fetales. Objetivos: Determinar los factores perinatales asociados a la baja puntuación de Apgar a los 5 minutos. Diseño: Estudio retrospectivo de casos y controles en los años 2015 y 2016. Institución: Hospital de la Mujer, Centro Hospitalario Pereira Rossell, Montevideo, Uruguay. Participantes: Se incluyeron todos los recién nacidos término con Apgar a los 5 minutos menor o igual a 5. Resultados: Hubo un total de 12.528 nacimientos de recién nacidos vivos de término en el HM. 34 casos de recién nacidos con Apgar a los 5 minutos menor o igual a 5. Esto corresponde al 0,27% de la población. No se identificaron diferencias estadísticamente significativas en cuanto a los principales factores asociados a asfixia perinatal. Conclusiones: En el análisis de esta población, la mayoría de los factores analizados no se asocia con los casos de Apgar a los 5 minutos menor o igual a 5 (depresión neonatal moderada-severa), por lo que la mayoría de estos casos pueden no ser evitables.

Introduction: Neonatal depression is one of the most frequent causes of admission of newborns to specialized units of neonatal care. Perinatal asphyxia is one of the causes of low Apgar score, and it is one of the clinical criteria for its diagnosis. Main risk factors associated with low Apgar scores can be maternal (age, obstetric pathologies, socioeconomic level, addictions, etc.), of labor and delivery or, fetal alterations. Objective: To determine the perinatal factors associated with the low Apgar score at 5 minutes. Design: Retrospective study of cases and controls in 2015 and 2016. Institution: Maternity, Women Hospital, Centro Hospitalario Pereira Rossell, Montevideo, Uruguay. Patients: We included all term newborns with Apgar at 5 minutes less than or equal to 5. Results: There was a total of 12,528 births of term full-term newborns in the HM. 34 cases of newborns with Apgar at 5 minutes less than or equal to 5. This corresponds to 0.27% of the population. No statistically significant differences were identified regarding the main factors associated with perinatal asphyxia. Conclusions: In the analysis of this population, most of the analyzed factors are not associated with cases of Apgar at 5 minutes less than or equal to 5 (moderate-severe neonatal depression), so that most of these cases may not be avoidable.

Introdução: A depressão neonatal é uma das causas mais freqüentes de internação de recém-nascidos em unidades especializadas de atenção neonatal. A asfixia perinatal é uma das causas do baixo índice de Apgar, sendo um dos critérios clínicos para o seu diagnóstico. Os principais fatores de risco associados aos baixos escores de Apgar podem ser maternos (idade, patologias obstétricas, nível socioeconômico, dependências, etc.), de trabalho de parto e parto, ou alterações fetais. Objetivos: Determine os fatores perinatais asociados ao baixo índice de Apgar aos 5 minutos. Design: Estudo retrospectivo de casos e controles nos anos de 2015 e 2016. Instituição: Hospital da Mulher, Centro Hospitalar Pereira Rossell, Montevidéu, Uruguai. Participantes: Todos os recém-nascidos a termo com Apgar a 5 minutos menor ou igual a 5 foram incluídos. Houve um total de 12.528 nascidos vivos a termo no MB. 34 casos de recém-nascidos com Apgar a 5 minutos menor ou igual a 5. Isso corresponde a 0,27% da população. Não foram identificadas diferenças estatisticamente significantes quanto aos principais fatores associados à asfixia perinatal. Conclusões: Na análise dessa população, a maioria dos fatores analisados não está associada aos casos de Apgar em 5 minutos menor ou igual a 5 (depressão neonatal moderada a grave), de modo que a maioria desses casos pode não ser evitável.

RESUMO

Objetivo: Determinar si las alteraciones en la ecografía transfontanelar es factor pronóstico para alteraciones del desarrollo motor durante los 2 primeros años de vida en neonatos a término diagnosticados con Encefalopatía Hipóxico-Isquémica, atendidos en el Hospital Regional Docente Las Mercedes y el Hospital Nacional Almanzor Aguinaga Asenjo, durante el periodo 2015-2017. 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)

RESUMO

ABSTRACT OBJECTIVE To analyze the association of characteristics recorded at the time of birth, including weight, occurrence of asphyxia, gestation duration, maternal age and education level, with death from diseases or malformations of the circulatory system in children under 18 years of age. METHODS The Brazilian Information System on Live Births and Information System on Mortality databases were linked and evaluated following a longitudinal cohort analysis strategy. The following independent variables were evaluated: characteristics recorded at the time of birth, including weight, occurrence of asphyxia, gestation duration, maternal age and education level. Dependent variables were death from diseases or malformations of the circulatory system in children under 18 years of age. Crude relative risks were estimated and relative risks were adjusted for the variables. RESULTS 6,380 deaths were linked to 4,282,260 birth records, yielding 5,062 pairs considered as true. Low birth weight (RR = 2.26), asphyxia at 1 (RR = 1.72) and 5 minutes (RR = 1.51), prematurity (RR = 1.50), maternal age ≥ 40 years (RR = 2.06), and low maternal education level (RR = 1.45) increased the probability of death caused by circulatory system diseases. In the association with death by malformations of the circulatory system, the predictive variables showed the same association profile, but with greater intensity. CONCLUSIONS Fetal and maternal factors are associated with increased mortality due to diseases and malformations of the circulatory system. Measures to control these factors and improve access to their diagnosis and treatment would contribute to reducing the number of deaths caused by diseases and malformations of the circulatory system. However, the identification of environmental influences during gestation and birth on the risk of death should be carefully considered due to being influenced by genetic factors.

RESUMO

Hypoxic-ischemic encephalopathy is a clearly recognizable clinical syndrome of in term newborns due to fetal asphyxia at birth. The incidence is 1.5 (95% CI 1.3 to 1.7) but it ranges from 1-8 and 25 out of every 1000 born in developed and developing countries, respectively. The most frequent causes are detachment of the placenta, prolapse of the umbilical cord and uterine rupture. The diagnostic criteria include partial or total incapacity for the newborn to cry and breath at birth even when stimulated, requiring assisted ventilation in the delivery room, Apgar < 5 in 5 and 10 minutes, acidemia (pH ≤ 7 and / or bases deficit ≥ 12 mmol/l), alterations of the conscience and the reflexes of Moro, grasping and suction, muscular stretching and muscle tone. The clinical forms are mild, moderate and severe. In the mild forms, the recovery is total in three days without, or with minimal, neurodevelopmental alterations. The moderate and severe forms cause permanent neurological deficits and neurodevelopmental alterations (48%) or death (27%). The regular or amplitude integrated EEG and the magnetic and spectroscopic magnetic resonance imaging performed between 24 and 96 hours and 7 and 21 days after birth, respectively, have a high diagnostic and prognostic value. Induced hypothermia (33.5° C for 72 hours) is recommended before 6 hours old. The result is a decrease in mortality (from 35% to 27%) and morbidity (from 48% to 27%).

RESUMO

La encefalopatía hipóxica-isquémica es un síndrome bien definido que afecta a los recién nacidos a término debido a asfixia fetal al nacer. La incidencia es 1-8 de cada 1000 nacidos en países desarrollados y asciende hasta 25 cada 1000 nacidos en países en desarrollo. Las causas más frecuentes son desprendimiento de la placenta, prolapso del cordón umbilical y rotura uterina. El criterio diagnóstico incluye incapacidad parcial o total del recién nacido para llorar y respirar al ser estimulado que requiere ventilación asistida en la sala de partos, Apgar < 5 en 5 y 10 minutos, acidemia (pH ≤ 7 y/o déficit de bases ≥ 12 mmol/l), alteraciones del estado de vigilia/sueño, de los reflejos primitivos y estiramiento muscular y tono muscular. En la forma leve la recuperación es total en tres días y sin (o con mínimas) secuelas de neurodesarrollo. En las formas moderadas y graves existen déficits neurológicos permanentes y alteraciones del neurodesarrollo (48%), 27% mueren y 25% son normales. El EEG regular o amplitud integrada y la resonancia magnética y espectroscópica realizados entre las 24 y las 96 horas y los 7 y 21 días de nacido respectivamente tienen un gran valor diagnóstico y pronóstico. Se recomienda hipotermia corporal (33.5 °C por 72 horas) antes de las 6 horas de nacido en las formas moderadas y graves. El resultado es una disminución de la mortalidad (de 35% a 27%) y de la morbilidad (de 48% a 27%).

RESUMO

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.

RESUMO

RESUMO Objetivo: Analisar características perinatais de crianças com transtorno do espectro autista (TEA). Métodos: Revisão retrospectiva dos prontuários medicos de 75 crianças com TEA, entre janeiro de 2008 e janeiro de 2015. Os critérios de inclusão foram o diagnóstico de TEA baseado no DSM-5 e o termo de consentimento assinado pelo responsável legal. O critério de exclusão foi ausência de todos os dados no prontuário médico. As variáveis analisadas foram: idade materna, prematuridade (idade gestacional menor que 37 semanas), baixo peso ao nascer (<2.500 g) e asfixia perinatal (Apgar menor que 7 no quinto minuto). Os dados foram avaliados por meio do teste de diferença entre as proporções (nível de significância de p<0,05). Resultados: Setenta e cinco pacientes foram incluídos no estudo. A idade materna variou de 21,4 a 38,6 anos (29,8±4,1 anos). O parto prematuro ocorreu em 14 (18,7%) pacientes, asfixia perinatal em 6 (8,0%) e baixo peso ao nascer em 32 (42,6%). As prevalências de prematuridade, asfixia perinatal e baixo peso ao nascer entre as crianças com TEA neste estudo foram maiores do que as prevalências gerais dessas condições entre todos os nascidos vivos em nosso país, região e estado, as quais são, respectivamente, 11,5, 2,3 e 8,5% no Brasil, 11,0; 2,2 e 8,5% na região Sul e 10,5, 2,0 e 8,4% no estado do Paraná. Conclusões: Nossos achados mostraram maior prevalência de prematuridade, baixo peso ao nascer e asfixia perinatal em crianças com TEA. Algumas limitações são o desenho retrospectivo do estudo e a amostra de pequeno tamanho. Grandes estudos prospectivos são necessários para esclarecer a possível associação entre intercorrências perinatais e TEA.

ABSTRACT Objective: To analyze perinatal features of children with autism spectrum disorder (ASD). Methods: Retrospective review of the medical records of 75 children with ASD, between January 2008 and January 2015. Inclusion criteria were diagnosis of ASD based on DSM-5 criteria, and the informed consent form signed by the person who is legally responsible. The exclusion criterion was missing on the medical record. The variables analyzed were maternal age, prematurity (gestational age under 37 weeks), low birth weight (<2,500 g), and perinatal asphyxia (5th minute Apgar score <7). Data were analyzed using the difference between proportions test, being significant p<0.05. Results: Seventy-five patients were included. Maternal age ranged from 21.4 to 38.6 years (29.8±4.1 years). Premature birth occurred in 14 (18.7%) patients, perinatal asphyxia in 6 (8.0%), and low birth weight in 32 (42.6%) patients. The prevalence of prematurity, low birth weight, and perinatal asphyxia among the children in our study was higher than the general prevalence of these conditions among all live births in our country, region, and state, which are, respectively, 11.5, 2.3, and 8.5% in Brazil; 11.0, 2.2, and 8.5% in Southern Brazil; and 10.5, 2.0, and 8.4% in the state of Paraná. Conclusions: Our findings show a higher prevalence of prematurity, low birth weight, and perinatal asphyxia among children with ASD. Some limitations are the retrospective study design, and the small sample size. Large prospective studies are needed to clarify the possible association between perinatal complications and ASD.

RESUMO

INTRODUCTION: Perinatal asphyxia is one of the main causes of perinatal mortality and morbidity worldwide and it generates high costs for health systems; however, it has modifiable risk factors. OBJECTIVE: To identify the risk factors associated with the development of perinatal asphyxia in newborns at Hospital Universitario del Valle, Cali, Colombia. MATERIALS AND METHODS: Incident cases and concurrent controls were examined. Cases were defined as newborns with moderate to severe perinatal asphyxia who were older than or equal to 36 weeks of gestational age, needed advanced resuscitation and presented one of the following: early neurological disorders, multi-organ commitment or a sentinel event. The controls were newborns without asphyxia who were born one week apart from the case at the most and had a comparable gestational age. Patients with major congenital malformations and syndromes were excluded. RESULTS: Fifty-six cases and 168 controls were examined. Premature placental abruption (OR=41.09; 95%CI: 4.61-366.56), labor with a prolonged expulsive phase (OR=31.76; 95%CI: 8.33-121.19), lack of oxytocin use (OR=2.57; 95% CI: 1.08 - 6.13) and mothers without a partner (OR=2.56; 95% CI: 1.21-5.41) were risk factors for the development of perinatal asphyxia in the study population. Social difficulties were found in a greater proportion among the mothers of cases. CONCLUSIONS: Proper control and monitoring of labor, development of a thorough partograph, and active searches are recommended to ensure that all pregnant women have adequate prenatal care with the provision of social support to reduce the frequency and negative impact of perinatal asphyxia.
