RESUMO

ABSTRACT Introduction. Preterm birth is a major medical, social, and economic problem that causes a large proportion of neonatal mortality and morbidity, has a high impact on the healthcare system, and affects family quality of life. The weight of newborns with mothers with periodontal disease is significantly lower compared to mothers not affected by this oral disease. This adverse outcome is considered a global public health problem based on epidemiological data. Objective. To determine the association between the prevalence of preterm births and periodontal disease in Bolivia, Chile, and Colombia from 2000 to 2020. Materials and methods. This ecological study considered the population of women in Bolivia, Chile, and Colombia, according to the prevalence of preterm births and periodontal disease discriminated by age. The study covered the period between 2000 and 2020. The search strategy within the Institute for Health Metrics and Evaluation investigative tool included prevalence, age groups, causes of preterm births and periodontal disease, context and locations, women, and rates. Statistical analysis included a simple linear regression between preterm births and periodontal disease for each age group within each country. Results. Preterm birth rates were higher in the 15-19 years age group (Bolivia: 697,563; Chile: 844,864; Colombia: 804,126). The periodontal disease prevalence increased with age, as we observed in the 45-49 years group (Bolivia: 22,077,854; Chile: 34,297,901, Colombia: 32,032.830). According to age groups, the linear regression was statistically significant (p < 0.001) in all age groups for the Bolivian population over 30 years for the Colombian, and only in the 15-19 years group for the Chilean women. Conclusion. An association was found between preterm births and periodontal disease in all age groups in Bolivia, only in the group of 15 to 19 years in Chile, and 30 years and up in Colombia over the 20-year period.

RESUMO

A Pandemia de COVID-19 trouxe prejuízos irreparáveis para toda a sociedade. Para as mulheres grávidas, além das dúvidas sobre a gravidez, surgiram mais questionamentos relacionados ao risco de exposição e contaminação pelo novo Coronavírus. Grávidas contaminadas pela COVID-19 podem ter manifestações clínicas leves até casos mais graves que, quando associados a algumas comorbidades, aumentam a possibilidade de um parto cesariano de emergência ou um parto prematuro. Diante disso, o presente estudo teve como objetivo conhecer a percepção de mulheres no momento do trabalho de parto no período da Pandemia de COVID-19. Trata-se de um estudo exploratório, descritivo, com abordagem qualitativa, realizado em Unidade de Saúde da Família, da cidade do Recife. Houve predominância de mulheres de raça/cor parda, primíparas, com renda mensal de até um salário mínimo, que estavam em uma união estável, com ensino médio completo e que não trabalhavam fora de casa. Observou-se a discrepância entre a expectativa para o momento do parto e a realidade como este de fato aconteceu; as repercussões emocionais, como medo, ansiedade e depressão, associadas aos distúrbios de imagem, também foram fatores abordados. Os resultados obtidos contribuem para que o processo de trabalho da Atenção Básica possa ser repensado e o conhecimento adquirido acerca desse tema possa ajudar a equipe de Saúde da Família a proporcionar uma assistência à saúde de qualidade e direcionada ao acompanhamento deste público.

The COVID-19 Pandemic has brought irreparable damage to the whole society. For pregnant women, in addition to doubts about pregnancy, more questions appeared regarding the risk of exposure and contamination by the new Coronavirus. Pregnant patients contaminated by COVID-19 can have mild clinical manifestations to more severe cases, which when associated with some comorbidities increase the possibility of an emergency cesarean or premature delivery. In light of this, the objective of the present study was to know the women's perception at the time of labor in the COVID-19 Pandemic's period. This is an exploratory and descriptive study, with a qualitative approach, carried out in a Family Health Unit in Recife city. There was a predominance of women of brown race/color, primiparous, with a monthly income up to one minimum wage, who were in a stable union, had completed high school and who did not work outside the home. It could be observed the discrepancy between the expectation for the moment of delivery and the reality as it actually happened. The emotional repercussions, such as fear, anxiety, depression, associated with image disorders were also factors addressed. The obtained results contribute so that the work process of Primary Health Care can be rethought and the knowledge acquired on this topic can help the Family Health Team to provide quality health care and directed to the follow-up of this public.

RESUMO

Introduction: The birth of premature babies is a public health problem with a high impact on infant morbidity and mortality. About 40% of mortality in children under five years occurs in the first month of life. Objective: To identify the association between maternal sociodemographic factors, premature birth, and mortality in newborns under 37 weeks in Santiago de Cali, 2017-2019. Materials and methods: We conducted a descriptive, cross-sectional study. We evaluated the records of Cali's Municipal Public Health Office. We calculated the crude and adjusted odd ratios and confidence intervals (95%) using the logistic regression model, data processing in Stata 16, and georeferencing the cases in the QGIS software. Results: From 2017 to 2019, premature babies in Cali corresponded to 11% of births. Poor prenatal care increased 3.13 times the risk of being born before 32 weeks (adjusted OR = 3.13; 95% CI = 2.75 - 3.56) and 1.27 times among mothers from outside the city (adjusted OR = 1.27; 95% CI = 1.15-1.41). Mortality was 4.29 per 1,000 live births. The mortality risk in newborns weighing less than 1,000 g increased 3.42 times (OR = 3.42; 95% CI = 2.85-4.12), delivery by cesarean section in 1.46 (OR = 1.46; CI 95% = 1.14-1.87) and an Apgar score - five minutes after birth- lower than seven in 1.55 times (OR = 1.55; CI 95% = 1.23-1.96). Conclusions: We found that less than three prenatal controls, mothers living outside Cali, afro-ethnicity, and cesarean birth were associated with prematurity of less than 32 weeks. We obtained higher mortality in newborns weighing less than 1,000 g.

Introducción: El nacimiento de bebés prematuros es un problema de salud pública con gran impacto en la morbimortalidad infantil: cerca del 40 % de las muertes de niños menores de cinco años sucede en el primer mes de vida. Objetivos: Identificar la asociación entre los factores sociodemográficos maternos, el parto prematuro y la mortalidad en recién nacidos menores de 37 semanas en Santiago de Cali, 2017-2019. Materiales y métodos: Se hizo un estudio descriptivo transversal. Se evaluaron los registros de la Secretaría de Salud Pública Municipal de Cali. Se calcularon las razones de probabilidad y los intervalos de confianza (95 %) crudos y ajustados mediante el modelo de regresión logística, en tanto que los datos se procesaron en Stata 16 y los casos se georreferenciaron con el programa QGIS. Resultados: Entre el 2017 y el 2019, los nacimientos de bebés prematuros en Cali correspondieron al 11 %. El control prenatal deficiente aumentó 3,13 veces el riesgo de nacer con menos de 32 semanas (OR ajustado = 3,13; IC95% = 2,75-3,56) y, en madres de municipios fuera de la ciudad, 1,27 veces (OR ajustado = 1,27; IC95% = 1,15-1,41). La mortalidad fue de 4,29 por 1.000 nacidos vivos. Nacer con un peso menor de 1.000 g aumentó el riesgo de mortalidad en 3,42 veces (OR = 3,42; IC95% = 2,85-4,12) y, un puntaje Apgar menor de siete a los cinco minutos del nacimiento, en 1,55 veces (OR=1,55; IC95% = 1,23-1,96). Conclusiones: Se encontró que tener menos de tres controles prenatales, la procedencia de la madre fuera de Cali, ser afrodescendiente y el parto por cesárea, estaban asociados significativamente con la prematuridad de menos de 32 semanas. Hubo mayor mortalidad en los recién nacidos con menos de 1.000 gramos al nacer.

RESUMO

A mortalidade materna é inaceitavelmente alta. A hemorragia pós-parto encontra- se na primeira posição no mundo, tendo como principal causa específica a atonia uterina. Eventualmente, as medidas iniciais e a terapia farmacológica não são efetivas no controle do sangramento, impondo a necessidade de tratamentos invasivos, cirúrgicos ou não. Entre esses, o tamponamento uterino com balão requer recursos locais mínimos e não exige treinamento extensivo ou equipamento muito complexo. Entretanto, algumas dificuldades podem ocorrer durante a inserção, infusão ou manutenção do balão na cavidade uterina, com especificidades relacionadas à via de parto. Após o parto vaginal, a dificuldade mais prevalente é o prolapso vaginal do balão. Na cesárea, as principais dificuldades são a inserção e o posicionamento do balão na cavidade uterina, principalmente nas cesáreas eletivas. Este artigo revisa e ilustra as principais dificuldades e especificidades relacionadas ao tamponamento uterino com balões.

Maternal mortality is unacceptably high. Postpartum hemorrhage is ranked first in the world, with the main specific cause being uterine atony. Eventually, initial measures and pharmacological therapy are not effective in controlling bleeding, imposing the need for invasive treatments, surgical or not. Among these, uterine balloon tamponade requires minimal local resources and does not require extensive training or very complex equipment. However, some difficulties may occur during insertion, infusion, or maintenance of the balloon in the uterine cavity, with specificities related to the mode of delivery. After vaginal delivery, the most prevalent difficulty is vaginal balloon prolapse. In cesarean section, the main difficulty is the insertion and positioning of the balloon in the uterine cavity, especially in elective cesarean sections. This article reviews and illustrates the main difficulties and specificities related to uterine balloon tamponade.

Objective : To establish the association between pregestational obesity and the risk of birth alterations. Design: Retrospective cohort study. Institution: Hospital Central "Dr. Urquinaona", Maracaibo, Venezuela. Methods : Obstetric outcome of patients according to pregestational mass index -obese (group A), overweight (group B), and normal weight (group C)- attended between January and December 2021. Main study measures: Duration of pregnancy and duration, type and alterations of delivery. Results : A total of 2,250 deliveries were attended during the study period, of which 226 pregnant women were selected for analysis. The majority of the pregnant women (60.5%) were assigned to group A, 47 (20.8%) to group B, and 41 (17.5%) to group C. Pregnant women in group A had a higher probability of cesarean section (odds ratio (OR) 1.76; 95% confidence interval (95%CI), 1.03 - 2.98), prolonged labor (OR 2.09; 95%CI, 1.23 - 3.53) and prolonged pregnancy (OR 2.30; 95%CI, 1.32 - 4.01) compared to pregnant women in group C. The pregnant women in group B did not show statistically significant differences in the frequency of obstetric variables compared to the pregnant women in group C (p = ns). Conclusion : There was a significant association between pregestational obesity and the risk of birth alterations.

RESUMO

OBJECTIVE: To compare the manufacturing, infusion, and total times of handmade balloons for uterine tamponade using the El Hennawy and Alves techniques, given the failure of initial measures and uterotonic therapy to control postpartum hemorrhage. METHODS: An open clinical trial (clinical article) was conducted among 30 physicians, residents, and assistants in an Obstetrics Department. Each participant manufactured and infused one of two different balloons compared in the study, in a randomly predefined sequence. The manufacturing and infusion times were timed by the researchers and their medians were compared using the t test or Mann-Whitney U test. RESULTS: The manufacturing time of the El Hennawy balloon was 72 s lower in relation to the Alves balloon (P < 0.010). Regarding the infusion time, the Alves balloon was filled faster than the El Hennawy balloon (P < 0.010). The total time (manufacturing and infusion) of Alves balloon was also lower than the El Hennawy device (P < 0.010). CONCLUSIONS: Although the El Hennawy balloon was manufactured more quickly, the total time of manufacturing and infusing the Alves balloon was much faster, which makes it the most suitable device to be used in critical situations of postpartum hemorrhage.

RESUMO

AIM: To investigate the effectiveness of interventions to prevent the occurrence of perineal trauma in parturients. METHODS: A bibliographic search was carried out in Cochrane Library, MEDLINE via PUBMED, LILACS via Virtual Health Library (VHL), Embase, Scopus, CINAHL, Scielo, Web of Science, and PEDro databases. Randomized clinical trials evaluating the effects of any intervention to prevent perineal trauma during pregnancy and/or childbirth were included. There were no temporal or language restrictions. The risk of bias assessment was performed using the Revised Cochrane Risk-of-bias Tool for Randomized Trials. RESULTS: Fifty studies, with a total of 17,221 participants, were included in this meta-analysis. No intervention during childbirth was effective for the prevention of perineal trauma (RR = 1.07, 95% CI [0.98.1.18], p < 0.01, I2 = 83%) when compared to no intervention. However, a lower risk of perineal laceration was verified with techniques performed during pregnancy, when compared to no intervention (RR = 0.81, 95% CI [0.71, 0.93], p = 0.05, I2 = 47%). Among them, highlight the effects of perineal massage in preventing lacerations (RR = 0.69, 95% CI [0.54, 0.87], p < 0.01) when compared to no intervention. CONCLUSIONS: The techniques performed during pregnancy, especially perineal massage, are associated with a lower risk of perineal laceration.

RESUMO

SUMMARY OBJECTIVE: This systematic review and meta-analysis study was conducted to reveal the effect of Pilates on pain during pregnancy and labor. METHODS: The PubMed, ScienceDirect, MEDLINE, Ovid, EBSCO, CINAHL Plus, Cochrane Library databases, and Google Scholar databases were used to access the articles published in international journals, and the Dergipark, Turkish Clinics, and ULAKBİM databases were scanned to access the articles published in national journals between October 30 and November 30, 2022. The data were analyzed using Review Manager 5.4. RESULTS: This study included four articles. According to the meta-analysis results, it was elucidated that Pilates exercise during pregnancy was not statistically effective in reducing pain during pregnancy (Z=0.61, p=0.54), but it was effective in reducing pain intensity during labor (Z=11.20, p<0.00001). CONCLUSION: This study concluded that Pilates exercise was not effective in reducing pain during pregnancy but was effective in reducing labor pain. There is a need for more research on the subject.

RESUMO

Introducción: La amenaza de parto pretérmino es un problema de salud pública mundial y nacional. La prematuridad viene acompañada de complicaciones como inmadurez pulmonar y lesiones del sistema nervioso central, que requieren de tratamiento oportuno.Objetivo: Establecer una comparación objetiva de los resultados del tratamiento de la ame-naza de parto prematuro, mediante el uso de Nifedipina o Atosiban, realizando una revisión teórica actualizada del tema, con el propósito de ofrecer a la comunidad científica, una he-rramienta de consulta, sobre un tema frecuente y de alto riesgo materno fetal.Materiales y Métodos: Se realizó una búsqueda bibliográfica en las bases de datos: Google Scholar, Pubmed, Wiley Online Library, Biomed, Scopus, Medes, Medline, Pro Quest, Gale, Scopus, y ScIELO, Se incluyeron artículos publicados en revistas indexadas de alto impacto, en los últimos 5 años. Se valoró la calidad de los artículos incluidos, utilizando la metodología de Sacket, y el riesgo de sesgo, según la metodología Cochrane. Resultados: Se observó un consenso entre los autores consultados en que no existen dife-rencias significativas en el efecto tocolítico de atosiban y nifedipino Conclusiones:La literatura académica parece coincidir en que la efectividad de atosiban y ni-fedipino como agentes tocolíticos es similar, con ambos medicamentos se consigue prolongar el embarazo con riesgo de parto pretérmino, que es el propósito fundamental de la tocolisis.

Background: The threat of preterm birth is a global and national public health problem. Prematurity is linked to complications such as pulmonary immaturity and central nervous system lesions, which require timely treatment. Objective: To perform an objective comparison of the results of the treatment of the threat of premature delivery, using nifedipine or atosiban, carrying out an updated theoretical review of the subject, to offer the scientific community a tool for research on a frequent subject of high maternal and fetal risk. Materials y Methods: There was a bibliographic search in specialized databases. Articles published in high impact indexed journals in the last 5 years were included. The quality of the articles included was assessed, using the Sacket methodology, and the risk of bias, accor-ding to the Cochrane methodology. Results: There was an agreement among the authors consulted there are no significant differences in the tocolytic effect of atosiban and nifedipine. Conclusions: The academic literature seems to agree that the effectiveness of atosiban and nifedipine as tocolytic agents is similar, with both drugs prolonging pregnancy with the risk of preterm delivery, which is the fundamental purpose of tocolysis.

RESUMO

Abstract Objective To review concepts, definitions, and findings about fear of childbirth (FOC). Methods A bibliographic review was carried out through the main scientific databases in 2020. Results All 32 articles considered potentially relevant were analyzed. A recent study suggests that the global prevalence of FOC can reach up to 14%. Factors such as parity, gestational age, previous birth experience, age and nationality of the woman seem to influence FOC. Conclusion Fear of childbirth could be related to an increased risk of adverse obstetric outcomes such as maternal request for cesarean delivery, preterm birth, prolonged labor, postpartum depression, and post-traumatic stress. These evidence highlight the importance of the discussion regarding this topic.

Resumo Objetivo Revisar conceitos, definições e achados sobre medo do parto (MDP). Métodos Foi realizada uma revisão bibliográfica nas principais bases de dados científicas em 2020. Resultados Foram analisados todos os 32 artigos considerados potencialmente relevantes. Um estudo recente sugere que a prevalência global do MDP pode chegar a 14%. Fatores como paridade, idade gestacional, experiência anterior de parto, idade da mulher e nacionalidade parecem influenciar o MDC. Conclusão O MDC pode estar relacionado ao aumento do risco de desfechos obstétricos adversos, como solicitação materna de cesariana, parto prematuro, trabalho de parto prolongado, depressão pós-parto e estresse pós-traumático. Estas evidências destacam a importância da discussão sobre este tema.

RESUMO

Objetivo. Establecer la utilidad de los índices de vascularización cervical en la predicción de parto pretérmino inminente. Diseño. Estudio de casos-controles. Institución. Hospital Central "Dr. Urquinaona", Maracaibo, Venezuela. Participantes. Pacientes con parto pretérmino en los siguientes 7 días (grupo A) y embarazadas con parto pretérmino más allá de los 7 días (grupo B). Métodos. Las embarazadas fueron evaluadas utilizando ecografía transvaginal y seguidas hasta el parto. Principales medidas de resultado. Características generales, índices de vascularización cervical (índice de vascularización, índice de flujo e índice de vascularización / flujo), parto pretérmino inminente y eficacia pronóstica. Resultados. Fueron incluidas 350 pacientes, 75 mujeres presentaron parto pretérmino inminente (grupo A) y 251 pacientes fueron consideradas como controles (grupo B). Las pacientes del grupo A tuvieron valores significativamente más bajos del índice de vascularización e índice de flujo comparado con el grupo B (p = 0,0122 y p < 0,0001, respectivamente). Las pacientes del grupo B presentaron valores significativamente más altos de índice de vascularización / flujo comparadas con las pacientes del grupo A (p = 0,0103). Los tres índices y la combinación de estos no mostraron capacidad de discriminación de parto pretérmino inminente. Conclusiones. Las pacientes con parto pretérmino inminente presentan diferencias significativas en los índices de vascularización comparado con las pacientes que presentan parto pretérmino más allá de los 7 días de la evaluación ecográfica. Sin embargo, no son útiles en la predicción del parto pretérmino inminente.

Objective: To establish the usefulness of cervical vascularization low he in the prediction of impending preterm labor. Design: Case-control study. Institution: "Dr. Urquinaona" Central Hospital, Maracaibo, Venezuela. Participants: Patients with preterm delivery within 7 days (group A) and pregnant women with preterm delivery beyond 7 days (group B). Methods: Pregnant women were evaluated using transvaginal ultrasound and followed until delivery. Main outcome measures: General characteristics, cervical vascularity low he (vascularity index, low index and vascularity / low index), impending preterm delivery, and prognostic efficacy. Results: A total of 350 patients were included, 75 women presented imminent preterm labor (group A) and 251 patients were considered as controls (group B). Patients in group A had significantly lower values of vascularization index and low index compared to group B (p = 0.0122 and p < 0.0001, respectively). Patients in group B had significantly higher values of vascularization / low index compared to patients in group A (p = 0.0103). The three low he and the combination of these did not show the ability to discriminate imminent preterm labor. Conclusions: Patients with imminent preterm labor showed significant differences in the vascularization low he compared to patients presenting preterm labor beyond 7 days of ultrasound evaluation. However, they are not useful in predicting impending preterm labor.

RESUMO

OBJETIVO: Evaluar el rendimiento del Gram, la glucosa y los leucocitos en líquido amniótico para el diagnóstico de respuesta inflamatoria fetal y materna en pacientes con parto pretérmino. MÉTODO: Estudio de rendimiento de pruebas diagnósticas. Se incluyeron 63 pacientes a quienes se les realizó amniocentesis por sospecha de infección intraamniótica. Se estudió la placenta y se comparó con el Gram, la glucosa y el recuento de leucocitos en líquido amniótico para ver su relación con la respuesta inflamatoria. Se evaluaron la sensibilidad, la especificidad, las razones de verosimilitud (LR, likelihood ratio), los valores predictivos y el valor de kappa. RESULTADOS: Las pruebas con mejor rendimiento fueron en conjunto la glucosa 50/mm3 en líquido amniótico, con una especificidad del 94,3% (intervalo de confianza del 95% [IC95%]: 84,6-98,1), LR + 8,83 (IC95%: 2,5-31,2) y kappa de 0,48 (IC95%: 0,15-0,82). También se consideró la propuesta de un nuevo punto de corte para el recuento de leucocitos en líquido amniótico en la respuesta inflamatoria fetal. CONCLUSIONES: La combinación del recuento de leucocitos en líquido amniótico y los valores de glucosa mejora el rendimiento para el diagnóstico de respuesta inflamatoria fetal en comparación con la histopatología de la placenta, lo que proporciona información útil para el enfoque de los recién nacidos.

OBJECTIVE: To evaluate the performance of Gram, glucose and leukocytes in amniotic fluid for the diagnosis of fetal and maternal inflammatory response in patients with preterm delivery. METHOD: A diagnostic performance test study was carried out. Sixty-three patients with preterm labor were included who underwent amniocentesis due to suspected intra-amniotic infection. Histopathology of the placenta was studied and compared with the Gram result, glucose and leukocyte count in amniotic fluid, and their relationship with the maternal and fetal inflammatory response. Sensitivity, specificity, likelihood ratios, predictive values, and kappa were evaluated. RESULTS: The tests with the best performance were overall glucose 50/mm3 in amniotic fluid for the diagnosis of the fetal inflammatory response, with a specificity of 94.3% (95% confidence interval [95% CI]: 84.6-98.1%), likelihood positive ratio 8.83 (95% CI: 2.5-31.2) and kappa of 0.48 (95% CI: 0.15-0.82). A new cut-off point for leukocyte count in amniotic fluid to diagnose fetal inflammatory response was proposed. CONCLUSIONS: The combination of amniotic fluid leukocyte count and amniotic fluid glucose values improves performance for the diagnosis of inflammatory response compared with placental histopathology, providing useful information for newborns approach.

RESUMO

Introducción. La progesterona es una hormona que favorece el mantenimiento del embarazo, es la protagonista de la fisiopatología del trabajo de parto pretérmino. De esta manera, se propone realizar una revisión sistemática que permita demostrar la utilidad de la progesterona natural micronizada en la mitigación de los efectos deletéreos del trabajo de parto pretérmino. Metodología. Revisión sistemática en la que se utilizaron los términos "MeSH" y "No ­ MeSH". Se empleó el programa "Publish or Perish" y bases de datos como: Medline, PubMed, Embase, Clinical Key, Cochrane Library, Scopus y Google Scholar. Se incluyeron artículos de revisión, meta-análisis, artículos originales (publicaciones preliminares o completas), resúmenes de congresos, seminarios publicados, libros de texto, protocolos hospitalarios regionales y consensos nacionales, en donde cada autor evaluó individualmente cada artículo y aplicó la herramienta CASPE. Resultados. En la literatura no es posible encontrar pautas concisas internacionales sobre el uso de la progesterona micronizada frente a la amenaza de trabajo de parto pretérmino (TPP). En general, para la mitigación del trabajo de parto, según lo analizado por los autores, se recomienda usar progesterona natural micronizada en cápsulas de 100 a 400 mg/día vía oral o 100 a 200 mg cada 12 a 24 horas vía vaginal. Desde la semana 16 hasta la semana 36 de gestación por vía oral y desde la semana 24 a 34 de gestación por vía vaginal. Discusión. El uso de la progesterona micronizada ha demostrado mitigar complicaciones posteriores al trabajo de parto pretérmino, sin embargo, no hay consenso sobre la dosificación y las vías de administración. Sumado a lo anterior, los estudios analizados pueden contener sesgos, por lo que se deja a elección del clínico el uso este medicamento. Conclusiones. La progesterona natural micronizada podría ser empleada para mitigar el trabajo de parto pretérmino según los artículos analizados por los autores a lo largo de la revisión. Sin embargo, se necesitan más estudios para legitimar dicha hipótesis.

Introduction. Progesterone is a hormone that favors maintaining pregnancy. It is the protagonist of the physiopathology of preterm labor. In this sense, a systematic review is proposed to demonstrate the usefulness of natural micronized progesterone in mitigating the harmful effects of preterm labor. Methodology. A systematic review in which the terms "MeSH" and "No ­ MeSH" were used. The "Publish or Perish" program was used, as well as databases, such as: Medline, PubMed, Embase, Clinical Key, Cochrane Library, Scopus, and Google Scholar. Review and meta-analysis articles, original articles (preliminary or complete publications), congress summaries, published seminars, textbooks, regional hospital protocols and national consensuses were included, in which each author individually assessed each article and applied the CASPE tool. Results. It was not possible to find concise international guidelines on using micronized progesterone for the threat of preterm labor (PTL) in literature. According to what the authors analyzed, for the mitigation of labor it is generally recommended the use of natural micronized progesterone in 100 to 400 mg/day capsules orally or 100 to 200 mg every 12 to 24 hours through the vagina. From week 16 to week 36 of pregnancy orally and from week 24 to 34 through the vagina. Discussion. Using micronized progesterone has demonstrated mitigating complications subsequent to preterm labor. However, there is no consensus on dosage and routes of administration. Added to the above, the analyzed studies may contain biases, reason why using this medication is left to the physician's discretion. Conclusions. Natural micronized progesterone can be used to mitigate preterm labor according to the articles the authors analyzed throughout the review. However, more studies are needed to validate this hypothesis.

RESUMO

A Síndrome Respiratória Aguda Grave Coronavírus 2 foi declarada pela Organização Mundial da Saúde como pandemia, em março de 2020. O quadro clínico da COVID-19 é bastante variável, visto que alguns pacientes são assintomáticos. Diante desta problemática objetivou-se quantificar e descrever os principais desfechos de partos em gestantes e recém-nascidos com resultado positivo para COVID-19. Trata-se de pesquisa epidemiológica, documental, retrospectiva, com abordagem quantitativa, utilizando-se das fichas de notificação das gestantes positivas para COVID-19 e a declaração de nascidos vivos dos casos com desfecho do parto. O estudo foi realizado com 119 gestantes, destas, 48 eram puérperas, sendo pacientes que tiveram resultado positivo para COVID-19, apresentando maior contaminação mulheres em idade fértil de 15 a 39 anos, solteiras e com ensino superior incompleto. Os sintomas mais relatados nas gestantes com COVID-19 foram cefaleia e tosse. A grande maioria dos casos teve desfecho positivo em relação à gestação.

Severe Acute Respiratory Syndrome Coronavirus 2 was declared a pandemic by the World Health Organization in March 2020. The clinical picture of COVID-19 is quite variable, as some patients are asymptomatic. In view of this problem, the objective was to quantify and describe the main outcomes of childbirth in pregnant women and newborns with a positive result for COVID-19.This an epidemiological, documentary, retrospective research, with a quantitative approach, using the notification forms of pregnant women positive for COVID-19 and the declaration of live births of cases with delivery outcome. The study was carried out with 119 pregnant women, of which 48 were postpartum women, being patients who tested positive for COVID-19, with greater contamination women childbearing age from 15 to 39 years old, single and with incomplete higher education.

RESUMO

Abstract Introduction: The duration of labor and the immediate puerperium are affected by obstetric and maternal-fetal factors. Interventions to provide obstetric analgesia may prolong the hospital stay. Objective: To characterize the procedure for obstetric analgesia and describe the time elapsed between analgesia and delivery and postpartum surveillance in healthy mothers. Methods: Observational, descriptive trial. The time elapsed between analgesia and delivery, and postpartum surveillance were measured in healthy pregnant women with vaginal delivery and a prescription of a neuraxial analgesia technique. Results: 226 patients were included. The mean time elapsed between analgesia an delivery was 4 hours (IQR 3-7). 50.7 % (n=114) received early analgesia (neuraxial technique with ≤ 4 centimeters of cervical dilatation), of which 48.2 % (n = 109) experienced a duration of analgesia until delivery longer than expected. The mean cervical dilatation at the time of the neuraxial approach was 4 centimeters (IQR 4-6) and the epidural technique was the most frequently used - 92.9 % (n = 210). The mean postpartum surveillance was 20 hours (IQR 15-27). Conclusions: Half of the patients included received early analgesia and around fifty percent of them took longer than expected in completing delivery. The postpartum surveillance time was consistent with the provisions of the Ministry of Health and with the current trend of a short postpartum surveillance aimed at early hospital discharge and the benefits thereof.

Resumen Introducción: La duración del trabajo de parto y del puerperio inmediato se afectan por factores obstétricos y maternofetales. Las intervenciones para brindar analgesia obstétrica pudieran prolongar el tiempo total de estancia hospitalaria. Objetivo: Caracterizar el procedimiento de analgesia obstétrica y describir los tiempos entre analgesia y parto y vigilancia posparto en maternas sanas. Métodos: Estudio descriptivo observacional. Se midieron los tiempos entre analgesia y parto y vigilancia posparto en gestantes sanas, cuya vía final del parto fuera vaginal con indicación y aplicación de alguna técnica de analgesia neuroaxial. Resultados: Se incluyeron 226 pacientes. La mediana del tiempo de analgesia hasta el parto fue de 4 horas (RIC 3-7); el 50,7 % (n = 114) recibió analgesia temprana (técnica neuroaxial a ≤ 4 centímetros de dilatación cervical), de las cuales el 48,2 % (n = 109) tuvo un tiempo de analgesia hasta el parto mayor al esperado. La mediana de dilatación cervical al momento del abordaje del neuroeje fue de 4 centímetros (RIC 4-6) y la técnica epidural fue la más frecuente, 92,9 % (n = 210). La mediana de tiempo de vigilancia posparto fue de 20 horas (RIC 15-27). Conclusiones: La mitad de las pacientes incluidas recibió analgesia temprana y cerca de la mitad tardó más de lo esperado en finalizar su gestación. El tiempo de vigilancia posparto fue acorde con lo establecido por el Ministerio de Salud y con la tendencia actual de una vigilancia posparto corta que apunte a un alta temprana y sus beneficios.

RESUMO

BACKGROUND: Nonpharmacological labor pain management methods (NPLPMM) are noninvasive, low-cost practices that may play a role in reducing the rates of unnecessary cesarean birth. We aimed to evaluate whether the NPLPMM is associated with the mode of birth. METHODS: We conducted a retrospective cohort study with clinical records of all women admitted for birth from January 2013 to December 2017. Records of women who had spontaneous labor or received induction or augmentation of labor during hospitalization were eligible for the study. We estimated the risk ratios for cesarean birth in general linear models using the Poisson regression with adjustments for the following variables: age, ethnicity, schooling, parity, gestational age, previous cesarean birth, spontaneous labor before admission, or induction/augmentation of labor. RESULTS: Within the total of 3,391 medical records, 40.1% had the use of a nonpharmacological labor pain management method registered. Cesarean rate among the study population was 44.2%. The use of NPLPMM decreased the risk of cesarean birth by 78% (OR = 0.22; 95% CI 0.19-0.26). History of a previous cesarean birth (RR = 2.63; 95% CI 2.35-2.64), the lack of use of NPLPMM (RR = 2.46; 95% CI 2.22-2.72), and primiparity (RR = 2.09; 95% CI 1.86-2.34) were the strongest risk factors for cesarean birth in the cohort. DISCUSSION: The use of NPLPMM may be an effective strategy to reduce unnecessary cesarean birth. Further studies to identify the efficacy of each method may help health professionals to offer more appropriate methods at different stages of labor.
