ABSTRACT
A perfusão arterial reversa gemelar é uma anormalidade rara que pode ocorrer em gestações gemelares monocoriônicas. Consiste em uma alteração na circulação fetoplacentária, com desvio de sangue de um dos gemelares para o outro, por meio de anastomoses arterioarteriais e venovenosas na superfície placentária e anastomoses arteriovenosas em áreas de circulação placentária compartilhada. O feto bombeador pode desenvolver insuficiência cardíaca devido ao aumento do débito cardíaco, e o feto receptor, perfundido por sangue pobre em oxigênio por meio do fluxo reverso, é severamente malformado, incompatível com a vida extrauterina. Este artigo apresenta o caso de uma gestação gemelar monocoriônica diamniótica, com manejo clínico conservador. O objetivo é relatar um caso de complicação rara de gestações monozigóticas e revisar condutas para diagnóstico e manejo adequado.(AU)
Twin reverse arterial perfusion is a rare abnormality that can occur in monochorionic twin pregnancies. It consists of an alteration in the fetal-placental circulation, with blood diversion from one of the twins to the other, through arterio-arterial and veno- venous anastomosis on the placental surface and arterio-venous anastomosis in areas of shared placental circulation. The pumping fetus may develop heart failure due to increased cardiac output, and the recipient fetus, perfused by oxygen-poor blood through reverse flow, is severely malformed, incompatible with extrauterine life. This article presents the case of a monochorionic diamniotic twin pregnancy, with conservative clinical management. The objective is to report a case of rare complication of monozygotic pregnancies and review procedures for diagnosis and adequate management.(AU)

INTRODUCTION@#Umbilical cord milking (UCM) is a method that allows for postnatal placental transfusion. The benefits of UCM have been demonstrated in some studies, but knowledge about its haemodynamic effects in term infants is limited. The aim of this study was to evaluate the haemodynamic effects of UCM in term infants.@*METHODS@#In this prospective, randomised controlled study, 149 healthy term infants with a birth week of ≥37 weeks were randomly assigned to either the UCM or immediate cord clamping (ICC) group. Blinded echocardiographic evaluations were performed in all the neonates in the first 2-6 h.@*RESULTS@#Superior vena cava (SVC) flow measurements were higher in the UCM group compared to the ICC group (132.47 ± 37.0 vs. 126.62 ± 34.3 mL/kg/min), but this difference was not statistically significant. Left atrial diameter (12.23 ± 1.99 vs. 11.43 ± 1.78 mm) and left atrium-to-aorta diastolic diameter ratio (1.62 ± 0.24 vs. 1.51 ± 0.22) were significantly higher in the UCM group. There were no significant differences in other echocardiographic parameters between the two groups.@*CONCLUSION@#We found no significant difference in the SVC flow measurements in term infants who underwent UCM versus those who underwent ICC. This lack of significant difference in SVC flow may be explained by the mature cerebral autoregulation mechanism in term neonates.

A iniquidade racial é a desigualdade em oportunidades e condições de vida que acontece em decorrência da etnia de uma pessoa. Indivíduos pretos, pardos e indígenas são modelos de povos que resistem aos desafios subsequentes dos processos históricos de segregação. Objetivo: Verificar a influência dos aspectos raciais na prática de violência obstétrica na atenção ao parto e nascimento. Métodos: Trata-se de um estudo com abordagem quantitativa, de corte transversal, com coleta de dados prospectiva, realizado em uma maternidade pública na cidade de Goiânia, Goiás. Resultados: Pode-se determinar um cuidado menos satisfatórios para as mulheres negras quando comparado com as brancas para a maioria dos indicadores avaliados neste estudo. Mulheres pretas e pardas têm maior chance de sofrerem manobra de Kristeller, amniotomia precoce, privação alimentar no trabalho de parto, clampeamento imediato do cordão umbilical e menor chance de contato pele a pele e de ser ofertado métodos não farmacológicos para o alívio da dor. Conclusão: O fator raça/cor influencia no tratamento em que as mulheres recebem dentro do estabelecimento de saúde.
Racial inequity is inequality in opportunities and living conditions that occurs as a result of a person's ethnicity. Black, brown and indigenous individuals are models of peoples who resist the subsequent challenges of historical processes of segregation. Objective: To verify the influence of racial aspects in the practice of obstetric violence in labor and birth care. Methods: This is a cross-sectional study with a quantitative approach, with prospective data collection, carried out in a public maternity hospital in the city of Goiânia, Goiás. Results: Less satisfactory care can be determined for black women when compared to white women for most of the indicators evaluated in this study. Black and brown women are more likely to undergo the Kristeller maneuver, early amniotomy, food deprivation during labor, immediate clamping of the umbilical cord and less chance of skin-to-skin contact and being offered non-pharmacological methods for pain relief. Conclusion: The race/color factor alone influences the treatment that women receive within the health establishment.

OBJECTIVES@#To study the influence of umbilical cord milking versus delayed cord clamping on the early prognosis of preterm infants with a gestational age of <34 weeks.@*METHODS@#PubMed, Web of Science, Embase, the Cochrane Library, CINAHL, China National Knowledge Infrastructure, Wanfang Data, Weipu Database, and SinoMed were searched for randomized controlled trials on umbilical cord milking versus delayed cord clamping in preterm infants with a gestational age of <34 weeks published up to November 2021. According to the inclusion and exclusion criteria, two researchers independently performed literature screening, quality evaluation, and data extraction. Review Manger 5.4 was used for Meta analysis.@*RESULTS@#A total of 11 articles were included in the analysis, with 1 621 preterm infants in total, among whom there were 809 infants in the umbilical cord milking group and 812 in the delayed cord clamping group. The Meta analysis showed that compared with delayed cord clamping, umbilical cord milking increased the mean blood pressure after birth (weighted mean difference=3.61, 95%CI: 0.73-6.50, P=0.01), but it also increased the incidence rate of severe intraventricular hemorrhage (RR=1.83, 95%CI: 1.08-3.09, P=0.02). There were no significant differences between the two groups in hemoglobin, hematocrit, blood transfusion rate, proportion of infants undergoing phototherapy, bilirubin peak, and incidence rates of complications such as periventricular leukomalacia and necrotizing enterocolitis (P>0.05).@*CONCLUSIONS@#Compared with delayed cord clamping, umbilical cord milking may increase the risk of severe intraventricular hemorrhage in preterm infants with a gestational age of <34 weeks; however, more high-quality large-sample randomized controlled trials are needed for further confirmation.

Objetivo: Analisar se boas práticas de atenção ao parto estão sendo executadas e quais necessitam ser aperfeiçoadas no Hospital Materno Infantil Nossa Senhora de Nazaré (HMINSN), em Boa Vista-RR. Métodos: Foram registrados os partos normais de setembro de 2019 a março de 2020, pela equipe administrativa do hospital, na base de dados do Apice On. Nove recomendações de boas práticas da Organização Mundial da Saúde (OMS) foram avaliadas e comparadas com outros serviços do País. Resultados: Observou-se que, em comparação com outros serviços do Brasil, entre as nove práticas analisadas, quatro apresentaram melhor resultado no HMINSN, com alta proporção de acompanhantes (90,1%), aplicação de ocitocina no terceiro período (98,7%), amamentação na primeira hora pós-parto (81,5%) e baixo número de episiotomia (8,8%). Além disso, atingiu metas do Apice On em quatro boas práticas, que são a presença de acompanhante (meta: acima de 90%), a aplicação de ocitocina no terceiro período (meta: acima de 90%), o clampeamento tardio do cordão umbilical (meta: acima de 90%) e a episiotomia (meta: abaixo de 10%). Conclusão: Este estudo identificou que é preciso melhorar as taxas de prescrição de dieta livre e o contato pele a pele na primeira hora pós-parto. De modo geral, o HMINSN tem apresentado bons indicadores em relação a outros serviços do País e vem buscando aprimorar a organização da equipe e do serviço para que todas as recomendações da OMS sejam efetivamente praticadas.(AU)
Objective: Analyze whether good practices for child care are being carried out and which need to be improved at the Hospital Materno Infantil Nossa Senhora de Nazaré (HMINSN), in Boa Vista-RR. Methods: Normal deliveries from September 2019 to March 2020 were recorded by the hospital's administrative staff in the Apice On database. Nine recommendations of World Health Organization (WHO) good practices were evaluated and compared with other services in the country. Results: It was observed, in comparison with other services in Brazil, among the nine practices analyzed, four of them had better results at HMINSN, with a high proportion of companions (90.1%), application of oxytocin in the third period (98.7 %), breastfeeding in the first hour postpartum (81.5%) and low number of episiotomy (8.8%). In addition, it reached Apice On targets in four good practices, which are the presence of a companion (target: above 90%), the application of oxytocin in the third period (target: above 90%), the late clamping of the umbilical cord (target: above 90%) and episiotomy (target: below 10%). Conclusion: This study identified that it is necessary to improve the prescription rates of free diet and skin-to-skin contact, in the first postpartum hour. In general, HMINSN has presented good indicators in relation to other services in the country and has been seeking to improve the organization of the team and the service, so that all WHO recommendations are effectively practiced.(AU)

Há diversas publicações científicas evidenciando os benefícios do atendimento humanizado ao parto vaginal. Assim mesmo, os profissionais mais resistentes à readequação de suas tradicionais condutas são os médicos. Por isso, realizou-se uma revisão de literatura com objetivo de avaliar quais as melhores condutas a serem adotadas pelos Obstetras, nos partos em que forem responsáveis pelo atendimento. Os principais tópicos pesquisados foram as intervenções médicas diretas ou prescricionais. Avaliou-se a prescrição de dieta, permissão de acompanhante e doula, posição da parturiente, realização de amniotomia e episiotomia, e o clampeamento do cordão umbilical. Deve-se permitir a ingesta líquida e de alimentos leves e incentivar a participação de acompanhantes e doulas. Recomenda-se ainda a adoção de posições verticalizadas, o uso da amniotomia e da episiotomia somente em casos selecionados e o clampeamento tardio do cordão umbilical. Os resultados, em geral, apontam para uma diminuição de intervenções, respeitando os desejos das mulheres, sem abandonar a vigilância do bem-estar fetal.(AU)
There are several scientific publications demonstrating the benefits of humanized childbirth care. However, the most resistant professionals to readjust their traditional behaviors are physicians. Therefore, we carried out a literature review to evaluate what are the best measures to be adopted by Obstetricians in births that they are responsible for. The main topics studied were the direct or prescriptive medical interventions. It has been assessed diet prescription, companion and doula permission, labour's positioning, amniotomy and episiotomy performing and umbilical cord clamping. Liquids and food intake should be allowed and the participation of companions and doulas should be encouraged. It is also recommended the adoption of upright positions, selective use of amniotomy and episiotomy and late umbilical cord clamping. The results generally indicates interventions declining, in respect of women desires, without abandoning the fetal well-being surveillance.(AU)
