Anestesia combinada e métodos não farmacológicos para alívio da dor durante o trabalho de parto e satisfação materna: ensaio clínico randomizado

OBJECTIVE: The objective of this study was to compare maternal satisfaction with childbirth according to whether or not combined spinal-epidural anesthesia (CSE) of pain relief was used during labor. METHODS: A randomized, open clinical trial was performed with 70 pregnant women, 35 of whom received CSE anesthesia while 35 received only non-pharmacological forms of pain relief during labor. The variables evaluated were visual analogue scale (VAS) pain score, maternal satisfaction with the technique of pain relief used during childbirth and with delivery, the patient's intention to request the same technique in a subsequent delivery, and loss of control during delivery. RESULTS: VAS pain score decreased significantly in patients receiving CSE during vaginal delivery. Furthermore, maternal satisfaction with the technique of pain relief and with delivery was higher in the CSE group, and around 97% of the patients would repeat the same technique at future deliveries compared to 82.4% of the women in the group using only non-pharmacological methods. With respect to the women's impressions of their control during delivery, approximately half the women in both groups felt that they had lost control at some point during the process. CONCLUSION: The use of CSE was associated with a significant reduction in VAS pain scores during delivery and with greater maternal satisfaction with the pain relief method and with the childbirth process.OBJETIVOS: Comparar a satisfação materna com o processo do nascimento de acordo com a realização ou não de métodos farmacológicos para alívio da dor do trabalho de parto. MÉTODOS: Realizou-se um ensaio clínico randomizado com 70 parturientes, 35 das quais receberam anestesia combinada (raquidiana e peridural associadas) e 35 receberam métodos não farmacológicos para alívio da dor durante o parto vaginal. As variáveis estudadas foram: escores de dor pela Escala Visual Analógica (EVA), satisfação materna com a técnica analgésica e com o parto, desejo de repetir a técnica analgésica em parto posterior e perda do controle sobre o parto. A análise estatística foi realizada no programa Epi-Info 3.5.3, com base na intenção de tratar. RESULTADOS: Pacientes recebendo anestesia combinada (AC) durante o parto vaginal experimentaram uma diminuição significativa dos escores da EVA e maior satisfação materna com a técnica analgésica e com o parto. A maioria das parturientes, cerca de 97% do grupo da anestesia combinada, repetiu a técnica em partos futuros, contra 82,4% do grupo dos métodos não farmacológicos. No que diz respeito ao sentimento de controle do parto, aproximadamente metade das parturientes dos dois grupos sentiu que em algum momento do parto perdeu o controle deste, não havendo diferença significativa entre os grupos. CONCLUSÃO: O uso da AC está associado a uma significante diminuição dos escores da dor durante o parto, e maior satisfação materna com a técnica analgésica e com o parto.11211

Perinatal outcomes from preterm and early term births in a multicenter cohort of low risk nulliparous women

Preterm birth is the major contributor for neonatal and under-fve years mortality rates and also accounts for a short- and long-term adverse consequences up to adulthood. Perinatal outcomes may vary according to lots of factors as preterm subtype, late prematurity, which account for the vast majority of cases, country and population characteristics. An under-recognition of the perinatal outcomes and its associated factors might have underpowered strategies to provide adequate care and prevent its occurrence. We aim to estimate the frequency of maternal and perinatal outcomes in women with diferent categories of preterm and term births, factors associated with poorer perinatal outcomes and related management interventions. A multicentre prospective cohort in fve maternities in Brazil between 2015 and 2018. Nulliparous low-risk women with singletons were included. Comprehensive data were collected during three antenatal visits (at 19–21weeks, 27–29 weeks and 37–39 weeks). Maternal and perinatal outcomes were also collected according to maternal and neonatal medical records. Women who had spontaneous (sPTB) and provider-initiated (pi-PTB) preterm birth were compared to those who had term birth. Also, late preterm birth (after 34 weeks), and early term (37–38 weeks) were compared to full term birth (39–40 weeks). Bivariate analysis estimated risk ratios for maternal and adverse outcomes. Finally, a multivariate analysis was conducted to address factors independently associated with any adverse perinatal outcome (APO). In total, 1,165 women had outcome data available, from which 6.7% had sPTB, 4.0% had pi-PTB and 89.3% had a term birth. sPTB and pi-PTb were associated with poorer perinatal outcomes, as well as late sPTB, late pi-PTB and early term neonates. pi-PTB (RRadj 8.12, 95% CI [2.54–25.93], p-value 0.007), maternal weight gain between 20 and 27 weeks <p10 (RRadj 2.04, 95% CI [1.23–3.38], p-value 0.018) and participants from the Northeast centres (RRadj 2.35, 95% CI [1.11–4.95], p-value 0.034) were independently associated with APO. According to our fndings, Brazil would beneft from strategies to more accurately identify women at higher risk for PTB, to promote evidenced-based decision in preterm and early term providerinitiated deliveries, and to prevent perinatal adverse outcomes

Planning, Implementing, and Running a Multicentre Preterm Birth Study with Biobank Resources in Brazil: The Preterm SAMBA Study

Background. Our aim was to describe the steps in planning, implementing, and running a multicentre cohort study of maternal and perinatal health using a high-quality biobank comprised of maternal serum, plasma, and hair samples collected from five sites in Brazil. The Preterm SAMBA study, conducted by the Brazilian Network for Studies on Reproductive and Perinatal Health, was an innovative approach used to identify women at higher risk for preterm birth. It is also of great importance in the study of other maternal and perinatal complications in the context of Brazil, which is a middle-income country. Methods. We described phases of planning, implementing, and running the Preterm SAMBA study, a multicentre Brazilian cohort study of low-risk nulliparous pregnant women, to validate a set of metabolite biomarkers for preterm birth identified in an external cohort. Procedures and strategies used to plan, implement, and maintain this multicentre preterm birth study are described in detail. Barriers and experience cited in the current narrative are not usually discussed in the scientific literature or published study protocols. Results. Several barriers and strategies were identified in different phases of the Preterm SAMBA study at different levels of the study framework (steering committee; coordinating and local centres). Strategies implemented and resources used in the study are a legacy of the Brazilian Network, aimed at training collaborators in such complex settings. Conclusion. The Brazilian Network for Studies on Reproductive and Perinatal Health has gained some experience in conducting a multicentre cohort study using a resourceful biobank which may be helpful to other research groups and maternal/perinatal health networks that plan on employing a similar approach to a similar background.201

Use of metabolomics for predicting spontaneous preterm birth in asymptomatic pregnant women : protocol for a systematic review and meta-analysis

Preterm birth (PTB) is the leading cause of neonatal mortality and short-and long-term morbidity. The aetiology and pathophysiology of spontaneous PTB (sPTB) are still unclear, which makes the identification of reliable and accurate predictor markers more difficult, particularly for unscreened or asymptomatic women. Metabolomics biomarkers have been demonstrated to be potentially accurate biomarkers for many disorders with complex mechanisms such as PTB. Therefore, we aim to perform a systematic review of metabolomics markers associated with sPTB. Our research question is 'What is the performance of metabolomics for predicting spontaneous preterm birth in asymptomatic pregnant women?' We will focus on studies assessing metabolomics techniques for predicting sPTB in asymptomatic pregnant women. We will conduct a comprehensive systematic review of the literature from the last 10 years. Only observational cohort and case-control studies will be included. Our search strategy will be carried out by two independent reviewers, who will scan title and abstract before carrying out a full review of the article. The scientific databases to be explored include PubMed, MedLine, ScieLo, EMBASE, LILACS, Web of Science, Scopus and others. Ethics and dissemination This systematic review protocol does not require ethical approval. We intend to disseminate our findings in scientific peer-reviewed journal, the Preterm SAMBA study open access website, specialists' conferences and to our funding agencies93CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPES401636/2013-588881.134095/2016-01; 8881.134512/2016-01This research was supported by Brazilian National Research Council (grant number 401636/2013-5) and Bill and Melinda Gates Foundation (grant number OPP1107597—Grand Challenges Brazil: Reducing the burden of preterm birth, FIOTEC number 05/2013), which provided funding to PRETERM-SAMBA project (www.medscinet.com/samba).

Resultados neonatais no parto vaginal espontâneo comparados aos dos partos com fórcipe de Simpson-Braun em primíparas Neonatal outcome of spontaneous deliveries as compared to Simpson-Braun forceps deliveries in nulliparous women

OBJETIVO: comparar os resultados neonatais dos partos vaginais espontâneos ou assistidos com fórcipe de Simpson-Braun em nulíparas. MÉTODO: em estudo de corte retrospectivo foram avaliados dois grupos de primíparas atendidas no Centro Obstétrico do CAISM/UNICAMP, que tiveram parto vaginal sob analgesia epidural. O grupo fórcipe foi formado por 119 pacientes que tiveram parto a fórcipe de Simpson-Braun, e o grupo normal por 114 casos de parto vaginal espontâneo. Foram estudadas as variáveis neonatais imediatas como o estado do líquido amniótico e os índices de Apgar, assim como a evolução neonatal nos primeiros dias de vida. Para análise estatística foram utilizados os testes c², exato de Fisher e t de Student para comparação de médias e considerada significativa a diferença correspondente a p<0,05. RESULTADOS: as indicações para uso do fórcipe Simpson-Braun foram: alívio materno-fetal (90 casos) e abreviação de período expulsivo (29 casos). Nas pacientes atendidas com fórcipe Simpson-Braun houve 8 casos de laceração de canal de parto (6,7%), valor semelhante ao observado no grupo de parto vaginal espontâneo. As médias de dias de internação das puérperas e neonatos foram idênticas (2,4). Os dois grupos foram semelhantes quanto aos índices de Apgar menores que 7 no primeiro (7,5 e 4,3%) e quinto minuto (1,6 e 1,7%) e quanto ao peso dos recém-nascidos (3.146 e 3.016 g). A evolução neonatal foi semelhante nos dois grupos. CONCLUSÃO: o uso do fórcipe de Simpson-Braun mostrou-se seguro, quando comparado ao parto vaginal espontâneo.<br>PURPOSE: to compare maternal and neonatal outcomes between spontaneous vaginal and Simpson-Braun forceps deliveries in nulliparous women. METHOD: a retrospective study including two groups of nulliparous women, who had vaginal delivery under peridural anesthesia in the obstetric unit of the CAISM-UNICAMP: the forceps group included 119 women who had Simpson-Braun forceps delivery, and the normal group included 114 women who delivered spontaneously. Neonatal outcomes, such as Apgar score and the evolution in the first days of life, were studied. Data were compared in both groups and, for statistical analysis, c² test, Fisher exact, and Student t tests were used. The differences were considered significant when p<0.05. RESULTS: the indications for Simpson-Braun forceps delivery were maternal-fetal relief (90 cases) and abbreviation of the expulsive period (29 cases). In the forceps group there were 8 cases (6.7%) of vaginal injuries; a similar result was observed in the normal group. The number of hospitalization days for the parturient and the newborns was identical, 2.4 days. The newborns in the two groups had similar Apgar scores inferior to 7 at the first minute (7.5 vs 4.3%) and at the fifth minute (1.6 vs1.7%). The weight in the two groups had similar results (3,146 and 3,016 g). The first days of life did not differ between the groups. CONCLUSIONS: the use of Simpson-Braun forceps was safe, when compared to spontaneous vaginal delivery

Via de Parto e Resultados Perinatais em Gestantes Diabéticas

Objetivo: apresentar os resultados perinatais obtidos a partir da aplicação de um protocolo de assistência às gestantes diabéticas no Centro de Atenção Integral à Saúde da Mulher (CAISM) da UNICAMP. Métodos: foram estudadas 90 gestantes diabéticas que iniciaram controle pré-natal na instituição e foram submetidas a este protocolo. Foram comparadas com dois grupos controles de 180 gestantes cada: um constituído por gestantes pareadas por idade e número de gestações (controle A) e outro por gestantes aleatoriamente selecionadas (controle B). Nos três grupos foram avaliadas as seguintes variáveis: tipo de parto, indicações de cesárea, idade gestacional, índice de Apgar ao primeiro e quinto minuto de vida, peso e adequação de peso para idade gestacional, morbidade e mortalidade perinatal. Para a análise estatística utilizaram-se médias, desvio-padrão, os testes t de Student e do chi². Resultados: entre as gestantes diabéticas ocorreu maior incidência de cesáreas, recém-nascidos prematuros e grandes para a idade gestacional (GIG), assim como uma maior freqüência de patologias neonatais (hipoglicemia, hipocalcemia, hiperbilirrubinemia, desconforto respiratório e depressão neonatal). A incidência de Apgar <7 e a mortalidade perinatal foram significativamente maiores do que no grupo controle aleatoriamente selecionado, mas a diferença desapareceu quando se comparou ao grupo controle pareado por idade e número de gestações. Conclusões: apesar de o protocolo visar um perfeito controle metabólico nas gestantes diabéticas, os resultados perinatais ainda são desfavoráveis em comparação às gestantes não-diabéticas

Combined spinal-epidural anesthesia and non-pharmacological methods of pain relief during normal childbirth and maternal satisfaction: a randomized clinical trial

OBJECTIVE: The objective of this study was to compare maternal satisfaction with childbirth according to whether or not combined spinal-epidural anesthesia (CSE) of pain relief was used during labor. METHODS: A randomized, open clinical trial was performed with 70 pregnant women, 35 of whom received CSE anesthesia while 35 received only non-pharmacological forms of pain relief during labor. The variables evaluated were visual analogue scale (VAS) pain score, maternal satisfaction with the technique of pain relief used during childbirth and with delivery, the patient's intention to request the same technique in a subsequent delivery, and loss of control during delivery. RESULTS: VAS pain score decreased significantly in patients receiving CSE during vaginal delivery. Furthermore, maternal satisfaction with the technique of pain relief and with delivery was higher in the CSE group, and around 97% of the patients would repeat the same technique at future deliveries compared to 82.4% of the women in the group using only non-pharmacological methods. With respect to the women's impressions of their control during delivery, approximately half the women in both groups felt that they had lost control at some point during the process. CONCLUSION: The use of CSE was associated with a significant reduction in VAS pain scores during delivery and with greater maternal satisfaction with the pain relief method and with the childbirth process

Campinas, SP, Brasil.Background: Cluster-based studies in health research are increasing. An important characteristic of such studies is the presence of intracluster correlation, typically quantified by the intracluster correlation coefficient (ICC), that indicate the proportion of data variability that is explained by the way of clustering. The purpose of this manuscript was to evaluate ICC of variables studied in the Brazilian Multicenter Study on Preterm Birth. Methods: This was a multicenter cross-sectional study on preterm births involving 20 referral hospitals in different regions of Brazil plus a nested case–control study to assess associated factors with spontaneous preterm births. Estimated prevalence rates or means, ICC with 95% confidence intervals, design effects and mean cluster sizes were presented for more than 250 maternal and newborn variables. Results: Overall, 5296 cases were included in the study (4,150 preterm births and 1,146 term births). ICC ranged from <0.001 to 0.965, with a median of 0.028. For descriptive characteristics (socio-demographic, obstetric history and perinatal outcomes) the median ICC was 0.014, for newborn outcomes the median ICC was 0.041 and for process variables (clinical management and delivery), it was 0.102. ICC was <0.1 in 78.4% of the variables and <0.3 for approximately 95% of them. Most of ICC >0.3 was found in some clinical management aspects well defined in literature such as use of corticosteroids, indicating there was homogeneity in clusters for these variables. Conclusions: Clusters selected for Brazilian Multicenter Study on Preterm Birth had mainly heterogeneous findings and these results can help researchers estimate the required sample size for future studies on maternal and perinatal health
