Misoprostol and mid trimester termination of pregnancy in patients with two previous scars and more at Elwiya Maternity Teaching Hospital / Misoprostol e interrupção da gravidez no meio do trimestre em pacientes com duas cicatrizes anteriores e mais no Elwiya Maternity Teaching Hospital

Abstract Objectives: to determine efficiency and safety of three misoprostol regimens for 2nd trimester pregnancy termination in individuals with two or more cesarean section scars. Methods: a cross-sectional study included 100 pregnant ladies at 13th-26th weeks gestation with previous two cesarean sections (CSs) who were scheduled for pregnancy termination using misoprostol. Patients were conveniently assigned to 100µg/3h, 200µg/3h or 400 µg/3h regimens. Primary outcome was time to abortion, secondary outcomes were side effect and complications. Results: a significant association was found between number previous CSs and longer time to abortion (p=0.01). A highly significant association was identified between earlier gestational age and longer time to abortion (p<0.001). Lower side effects and complications were associated with 200 µg misoprostol every 3 hours of (p<0.001). Incomplete abortion was the most frequent recorded complication for the successive doses of misoprostol. Conclusions: misoprostol is an effective drug at low doses for pregnancy termination in women with prior two or more caesarean sections. However, its safety needs monitoring of the patient in the hospital to decrease morbidity and mortality behind its use.

Resumo Objetivos: determinar a eficiência e segurança de três regimes de misoprostol para interrupção da gravidez no segundo trimestre em indivíduos com duas ou mais cicatrizes de cesariana. Métodos: um estudo transversal incluiu 100 gestantes entre 13ª e 26ª semanas de gestação com duas cesarianas (CEs) anteriores que foram agendadas para interrupção da gravidez com uso de misoprostol. Os pacientes foram convenientemente designados para regimes de 100 µg/3 horas, 200 µg/3 horas ou 400 µg/3 horas. O desfecho primário foi o tempo para o aborto, os desfechos secundários foram efeitos colaterais e complicações. Resultados: foi encontrada associação significativa entre o número de cesáreas anteriores e o maior tempo até o aborto (p=0,01). Foi identificada associação altamente significativa entre idade gestacional mais precoce e maior tempo para abortar (p<0,001). Menores efeitos colaterais e complicações foram associados com 200 µg de misoprostol a cada 3 horas (p<0,001). O aborto incompleto foi a complicação mais frequente registrada para as doses sucessivas de misoprostol. Conclusões: o misoprostol é um medicamento eficaz em doses baixas para interrupção da gravidez em mulheres com duas ou mais cesarianas anteriores. Porém, sua segurança necessita de monitoramento do paciente no hospital para diminuir a morbimortalidade por trás de seu uso.

Increased Cesarean Section Rates during the COVID-19 Pandemic: Looking for Reasons through the Robson Ten Group Classification System / Aumento das taxas de cesárea durante a pandemia de COVID-19: procurando explicações por meio da Classificação de Robson

Abstract Objective To compare cesarean section (CS) rates according to the Robson Ten Group Classification System (RTGCS) and its indications in pregnant women admitted for childbirth during the first wave of the coronavirus disease 2019 (COVID-19) pandemic with those of the previous year. Materials and Methods We conducted a cross-sectional study to compare women admitted for childbirth from April to October 2019 (before the pandemic) and from March to September 2020 (during the pandemic). The CSs and their indications were classified on admission according to the RTGCS, and we also collected data on the route of delivery (vaginal or CS). Both periods were compared using the Chi-squared (χ2) test or the Fisher exact test. Results In total, 2,493 women were included, 1,291 in the prepandemic and 1,202 in the pandemic period. There was a a significant increase in the CS rate (from 39.66% to 44.01%; p = 0.028), mostly due to maternal request (from 9.58% to 25.38%; p < 0.01). Overall, groups 5 and 2 contributed the most to the CS rates. The rates decreased among group 1 and increased among group 2 during the pandemic, with no changes in group 10. Conclusion There was an apparent change in the RTGSC comparing both periods, with a significant increase in CS rates, mainly by maternal request, most likely because of changes during the pandemic and uncertainties and fear concerning COVID-19.

Resumo Objetivo Comparar as taxas de cesárea segundo a Classificação de Robson, assim como suas indicações, em mulheres admitidas para parto durante a primeira onda de doença do coronavírus 2019 (coronavirus disease 2019, COVID-19, em inglês), com as do ano anterior. Materiais e Métodos Conduzimos um estudo transversal que comparou as mulheres admitidas para parto entre abril e outubro de 2019 (pré-pandemia) e entre março e setembro de 2020 (durante a pandemia). As cesarianas e as suas indicações foram classificadas conforme o sistema proposto por Robson, e obteve-se a via de parto (vaginal ou cesárea). Ambos os períodos foram comparados usando-se os testes do Qui quadrado ou o exato de Fisher. Resultados Ao todo, 2.943 mulheres foram incluídas, das quais 1.291 antes da pandemia e 1.202 durante a pandemia. A taxa de cesárea aumentou significativamente (de 39.66% para 44,01%; p = 0,028), principalmente devido a desejo materno (de 9,58% para 25,38%; p < 0,01). Os grupos 5 e 2 foram os que mais contribuíram para as taxas de cesárea. Durante a pandemia, o grupo 1 reduziu sua frequência, enquanto o grupo 2 a aumentou. Conclusão Houve uma aparente mudança nas características da população conforme a classificação de Robson. Observou-se significativo aumento nas taxas de cesárea, principalmente por desejo materno, o que reflete possíveis incertezas e medos relacionados à COVID-19.

The effectiveness of preoperative diagnostic methods in predicting intra-abdominal adhesions before repeat cesarean section delivery.

OBJECTIVE: This study aimed to evaluate the effectiveness of skin appearance, striae gravidarum severity, and ultrasonographic "sliding sign" in predicting preoperative adhesions before repeat cesarean section delivery on the same patient and find the most useful one. METHODS: This was a prospective cohort study conducted on pregnant women with a history of cesarean section delivery. Davey's scoring system was used for stria evaluation. The scar was assessed using their visual appearance, and transabdominal ultrasonography was applied to detect sliding sign existence. Surgeons blinded to preoperative assessment graded the severity of intra-abdominal adhesions intraoperatively using Nair's scoring system. RESULTS: Of the 164 pregnant women with at least one previous cesarean section delivery, 73 (44.5%) had filmy or dense intra-abdominal adhesions. Statistically significant association was found between three groups regarding parity, previous cesarean number, scar appearance, total stria score, and sliding sign existence. Negative sliding sign had a likelihood ratio of 4.198 (95%CI 1.178-14.964) for the detection of intra-abdominal adhesions. Stria score and scar appearance were also valuable for detection adhesions with likelihood ratios of 1.518 (95%CI 1.045-2.205) and 2.405 (95%CI 0.851-6.796), respectively. After receiver operator characteristics curve analysis, striae score cutoff value in adhesion prediction was determined as 3.5. CONCLUSION: Stria score, scar appearance, and sliding sign are all significant predictors for intraperitoneal adhesions, and sliding sign, as an easy-to-apply, inexpensive, useful sonographic marker, is the most effective adhesion predictor before repeat cesarean section delivery compared to other known adhesion markers.

The association of timing of repeat cesarean with outcomes among a cohort of Guatemalan women with a history of prior cesarean birth.

BACKGROUND: The objective of this analysis was to observe whether maternal and perinatal/neonatal outcomes of birth vary by timing of repeat cesarean among women with a history of one prior cesarean birth in a Guatemalan cohort. METHODS: This secondary analysis was conducted using data from a prospective study conducted in communities in Chimaltenango, Guatemala through the Global Network for Women's and Children's Health Research. RESULTS: Between January 2017 and April 2020, 26,465 women delivered; 3,143 (11.9%) of those women had a singleton gestation and a history of prior cesarean delivery. 2,210 (79.9%) women with a history of prior cesarean birth had data available on mode of delivery and gave birth by repeat cesarean; 1312 (59.4%) were pre-labor cesareans while 896 (40.5%) were intrapartum cesarean births. Risk factors associated with an increased risk of intrapartum cesarean birth included hospital delivery as compared to "other" location (ARR 1.6 [1.2,2.1]) and dysfunctional labor (ARR 1.6 [1.4,1.9]). Variables associated with a reduced risk of intrapartum cesarean birth were hypertensive disease (ARR 0.7 [0.6,0.9]), schooling (ARR 0.9 [0.8,0.9]), and increasing age, which was associated with a very slight reduction in the outcome (ARR 0.99 [0.98,0.99]). Maternal and neonatal outcomes did not vary by type of cesarean birth. CONCLUSION: Outcomes of cesarean birth do not seem to vary by timing of repeat cesarean birth, with hypertensive disease increasing the likelihood of pre-labor cesarean. This information might be useful in counseling women that outcomes after failed trial of labor do not appear worse than those after pre-labor cesarean birth.

Listening to Haitian Women and their Health Care Providers: Insight into Shared Decision-making After Cesarean Section.

INTRODUCTION: Haitian women in Massachusetts have high rates of cesarean section and low rates of vaginal birth after cesarean, despite evidence suggesting that many are eligible to attempt vaginal birth after a previous cesarean. This qualitative study explored the cultural impact of previous surgical birth for Haitian women to inform the development of a patient-centered decision support program. METHODS: Key stakeholders included Haitian women with previous cesarean and their obstetric care providers. Haitian women participated in focus groups; care providers participated in focus groups and in-depth interviewing. RESULTS: Four prominent themes emerged surrounding childbirth decision-making: the importance of Haitian culture and beliefs; need for more information on birthing options; influence of family/friends; and pain as a considerable factor. CONCLUSION: We hypothesize that group counseling tailored to meet cultural values and needs of Haitian women may support all stakeholders as they work towards sharing decisions about birth after cesarean.

Repeated cesarean section and vaginal delivery after cesarean section in São Paulo State in 2012 / Repetição de cesárea e parto vaginal após cesárea, no Estado de São Paulo, em 2012

Abstract Objectives: describe mothers, pregnancies and newborns' characteristics according to the type of childbirth history and to analyze repeated cesarean section (RCS) and vaginal delivery after cesarean section (VBACS), in São Paulo State in 2012. Methods: data are from the Sistema de Informações sobre Nascidos Vivos (Live Birth Information Systems). To find the RCS's group, the current type of childbirth equal to cesarean section was selected and from these all the previous cesareans. To identify the VBACS's group all live birth with current vaginal delivery were selected and from these all previous cesareans. Mothers with a history of RCS and VBACS were analyzed according to the characteristics of the pregnancy, newborn and the childbirth hospital. Results: 273,329 mothers of live birth with at least one previous child were studied. 43% of these were born of RCS and 7.4% of VBACS. Mothers who underwent RCS are older and higher educated and their newborns presented a lower incidence of low birth weight. Early term was the most frequent rating for gestational age born of RCS. Live births were of VBACS and had greater proportions of late term. The RCS was more common in hospitals not affiliated with the Sistema Único de Saúde (SUS) (Public Health System) (44.1%). Conclusion: the high RCS's rates, especially in the private sector, highlight the necessity of improvements in childbirth care model in São Paulo.

Resumo Objetivos: descrever características das mães, da gestação e do recém-nascido, segundo histórico de tipo de parto, analisando repetição de cesárea (RC) e parto vaginal após cesárea (PVAC), no Estado de São Paulo, em 2012. Métodos: os dados são provenientes do Sistema de Informações sobre Nascidos Vivos. Para encontrar o conjunto RC, selecionou-se o tipo de parto atual igual a cesárea e destes buscou-se todos com cesárea anterior. Para identificar o grupo PVAC, selecionou-se os recém-nascido com parto atual vaginal e destes buscou-se todos com cesárea anterior. Foram analisadas mães com história de RC e PVAC, segundo características da gestação, do recémnascido e hospital do parto. Resultados: estudou-se 273.329 nascidos vivos de mães com pelo menos um filho anterior. Destes, 43% nasceram por RC e 7,4% por PVAC. As mães que realizaram RC são mais velhas e mais escolarizadas, seus recém-nascidos apresentaram menor proporção de baixo peso ao nascer. Termo precoce foi a mais frequente idade gestacional dos que nasceram por RC. Os recém-nascidos por PVAC apresentaram maiores proporções de termo tardio. RC foi mais frequente nos hospitais sem vínculo com o Sistema Único de Saúde (44,1%). Conclusão: as altas taxas de RC, principalmente no setor privado, evidenciam necessidade de melhoras no modelo de atenção ao parto em São Paulo.

Taxa de parto normal versus cesárea em gestantes com uma cesárea anterior e fatores associados / Normal birth rate versus cesarean in pregnant women and associated factors

Objetivo: Calcular taxa de parto vaginal e cesárea em pacientes com uma cesárea anterior e gestação a termo, bem como fatores associados à recorrência de cesaria- na. Métodos: Estudo caso-controle, por meio de dados de prontuário de gestantes a termo com uma cesárea prévia admitidas para parto na Maternidade Darcy Vargas do município de Joinville (SC), em 2019. Resultados: Foram analisadas 788 pacientes, das quais 331 (42,00%) tiveram parto normal (PN) e 457 (58,00%), cesárea (CS). O grupo PN foi composto por mulheres mais velhas (29; 28) e com mais gestações que o grupo CS, possuindo pelo menos um parto normal prévio (171; 57; p < 0,001). Como fator de risco para recorrência de cesárea, destacou-se a presença de colo desfavorável no momento do parto (47; 356; p < 0,001). Internação por trabalho de parto (284; 92; p < 0,001) e ruptura prematura de membranas (RUPREME) (33; 79; p = 0,030) estão entre os fatores de proteção para ocorrência de uma nova cesariana. Conclusão: A taxa de parto vaginal pós-cesariana (VBAC) foi de 42% e a de parto cesáreo foi de 58%, condi- zente com valores de referência mundiais. O fato de ter um ou mais partos normais anteriores e internar-se em trabalho de parto ou com RUPREME foi fator protetor contra a repetição da cesárea, enquanto o colo desfavorável no momento da inter- nação foi fator de risco. Há grande divergência na literatura, sendo necessários mais estudos para elaborar estratégias que auxiliem profissionais e pacientes a decidirem pela melhor via de parto após cesariana anterior.(AU)

Objective: To calculate the rate of vaginal and cesarean delivery in patients with pre- vious cesarean section and pregnancy to term, as well as factors associated with recur- rent abdominal delivery. Methods: Case-control study, by medical records of pregnant women to term with a previous cesarean section admitted for delivery at Maternity Dar- cy Vargas in the city of Joinville (SC) in 2019. Results: 788 patients, of which 331 (42,00%) had a normal delivery (PN) and 457 (58,00%) cesarean section (CS). The PN group was composed of older women (29;28), and who had more pregnancies than the CS group, having at least 1 previous vaginal birth (171; 57; p < 0,001). As a risk factor for cesarean recurrence, the presence of an unfavorable cervix at the time of delivery was highlighted (47; 356; p < 0,001). Hospitalization for labor (284; 92; p < 0,001) and premature rupture of membranes (33; 79; p = 0,030) are among the protective factors for the occurrence of a new cesarean section. Conclusion: The post-cesarean vaginal birth (VBAC) rate was 42% and the cesarean delivery rate was 58%, consistent with world reference values. The fact of having one or more previous normal bir- ths, hospitalization in labor or with premature rupture of fetal membranes were protective factors against the repetition of cesarean section, while the unfavorable cervix at the time of hospitalization was a risk factor. There is divergence in litera- ture, therefore more studies are needed to develop strategies that help professionals and patients to decide on the best way of delivery after a previous cesarean section.(AU)

Risk score for failed trial of vaginal birth after a previous cesarean section including data of labor course.

AIM: There is much discussion about the advantages and disadvantages of a trial of labor after cesarean (TOLAC). Some data suggest the greater the likelihood of success, the lower the risks of TOLAC. Our goal was to identify clinical and demographic variables associated with a failed TOLAC, available at admission for spontaneous labor and until 3 h later, with the aim of building two scores for risk of failed TOLAC. METHODS: This is a nested case-control study with live births to women with one previous cesarean, in a public Brazilian teaching hospital. Preterm, induction, noncephalic presentations, twins, fetal malformations were excluded. Cases were failed TOLAC, and controls, the successful TOLAC. It was accessed the association of the cases with 20 variables (P < 0.05). Associated variables were tested in multivariate analysis to build the scores, which were internally validated. RESULTS: We included 260 TOLAC, 42 cases and 218 controls. We found 11 variables associated with failed TOLAC. In the score to be applied at admission, we included hypertension, fundal height, previous vaginal birth and dilatation at admission. In the second score hypertension, fundal height at admission, membrane status and difference in dilatation 3 h after admission. Both scores presented good performance in the receiver-operator curve (areas under curve: 0.73 and 0.84, respectively). Both scores were translated into nomograms for clinical use. CONCLUSION: Two scores were built for risk of failed TOLAC, to be applied at admission and 3 h later. We believe that choosing the more favorable cases makes risks of TOLAC lower.

A systematic review and meta-analysis of cesarean delivery and other uterine surgery as risk factors for placenta accreta.

BACKGROUND: The incidence of placenta accreta has increased in recent years and it has been suggested that the rising trend in cesarean delivery and other uterine surgery is the underlying cause. OBJECTIVE: To explore the magnitude of the effect of performing single and repeat cesarean deliveries or other uterine surgery on the incidence of placenta accreta. SEARCH STRATEGY: Relevant databases were searched for papers published before August 1, 2018, using terms including "accreta" and "cesarean." SELECTION CRITERIA: Cohort studies assessing the risk of placenta accreta according to women's history of uterine surgery. DATA COLLECTION AND ANALYSIS: Meta-analyses were performed to assess the risks associated between uterine surgery and placenta accreta, hysterectomy, and uterine rupture. The I2 statistic was used to examine between-study heterogeneity. MAIN RESULTS: The risk of placenta accreta in a second pregnancy increased for women who had undergone a cesarean in their first pregnancy compared with vaginal delivery (OR 3.02; 95% CI, 1.50-6.08). Absolute risk of placenta accreta increased with the number of previous cesareans. The risk of uterine rupture and hysterectomy was also associated with the number of cesareans. CONCLUSIONS: Risk of placenta accreta, hysterectomy, and uterine rupture increases with the number of previous cesarean deliveries. PROSPERO: CRD42016050646.

Elective repeat cesarean delivery in women eligible for trial of labor in Brazil.

OBJECTIVE: To assess the hospital, maternal, and obstetric characteristics associated with elective repeat cesarean delivery (ERCD) among women eligible for trial of labor after cesarean (TOLAC) delivery in Brazil. METHODS: The present data were retrieved from the Birth in Brazil study, a national hospital-based cohort study conducted during 2011-2012. Data were collected from medical records and by interview. Univariate and hierarchical multiple logistic regression analyses were performed to analyze factors associated with ERCD among women with a previous cesarean delivery who were eligible for TOLAC. RESULTS: Among 2295 women considered eligible for TOLAC, 1516 (66.1%) had an ERCD; the overall cesarean delivery rate was 79.4%. In the private sector, almost all deliveries (95.3%) were performed by ERCD. In the public sector, ERCD was associated with socioeconomic (more years of schooling), obstetric (women's preference, no previous vaginal delivery, macrosomia), and hospital (mixed hospital, location in noncapital city, fewer than 1500 deliveries per year) characteristics. CONCLUSION: The ERCD rate in Brazil was high even in a low-risk group, indicating that nonclinical factors may be driving the decision for cesarean delivery. Efforts aiming to reduce cesarean deliveries in Brazil should target women with a previous cesarean delivery.

Manejo del acretismo placentario en Servicios de Obstetricia de hospitales de alta complejidad Aplicación de un Proyecto de atención integral multidisciplinario / PLACENTA ACCRETA: MANAGEMENT AT OBSTETRIC SERVICES IN HIGH COMPLEXITY HOSPITALS

Objetivo: El objetivo del estudio fue describir el manejo de los Trastornos Adherenciales de la Placenta en la Maternidad de alta complejidad recabando los datos tanto del servicio de Obstetricia del Hospital Nacional Profesor Alejandro Posadas y Hospital Naval Pedro Mallo Buenos Aires. Diseño: Estudio de tipo observacional, descriptivo y transversal. Análisis estadístico mediante Stata 12.0. Resultados: Durante el período comprendido entre enero de 2010 y diciembre de 2014 fueron atendidas 30 pacientes con trastornos adherenciales placentarios. La incidencia de acretismo placentario en ese periodo fue de 0.18 (30/16210 nacimientos). El 56.67% (17/30) de las cirugías fueron programadas con Hemodinamia. En el 96.67% (N=29) el resultado anátomo-patológico final fue Acretismo Placentario. Hubo un caso falso positivo. Cuatro casos presentaron complicaciones potencialmente graves "near miss". No se presentaron muertes maternas. Conclusiones: Los trastornos adherenciales placentarios se presentan como un nuevo desafío para los Servicios de Obstetricia por la aparición en forma "epidémica" de una enfermedad que era infrecuente. El manejo multidisciplinario es la clave para un correcto tratamiento. El Obstetra cumple el rol de coordinación del mismo, convocando a las diferentes especialidades. Será entonces, de capital importancia el aporte de todos para la correcta resolución de los casos.

The aim of the present report was to describe the management of the adherencial disorders of the placenta in a high complexity maternity. During the period between January 2010 and December 2014, 30 patients with placental adherencial disorders were assisted. The incidence of placenta accreta during that period, was 0.18 (30/16210 deliveries). The 96.67 % of surgeries were programmed with Hemodinamia. In the 96.67 % (N= 29) the final anatomo-pathological result was Placentary Accretism. There was a false positive case. Four cases presented complications potentially severe "near miss". None maternal deaths were observed in the survey. The placental adherencial disorders present as a new challenge for the Obstetric Services because of their apparition in an "epidemic" way of a disease that was unfrequent. The multidisciplinary management is the key for an adequate treatment. Obstetricians play a roll for coordination of the team, convoking the different specialities. There will be then, of great importance, the contribution of the totality for the proper resolution of the cases

Anesthesia for cesarean section in a patient with isolated unilateral absence of a pulmonary artery / Anestesia para cesariana em paciente com ausência unilateral isolada de artéria pulmonar

Abstract Background and objectives: Congenital unilateral absence of a pulmonary artery (UAPA) is a rare anomaly. Although there are several reports regarding pregnancy in patients with unilateral absence of a pulmonary artery, there are no case reports describing anesthesia for Cesarean section in a patient with unilateral absence of a pulmonary artery. Case report: We present a patient with unilateral absence of a pulmonary artery who underwent Cesarean sections twice at the ages of 24 and 26 years under spinal anesthesia for surgery and epidural analgesia for postoperative pain relief. Both times, spinal anesthesia and epidural analgesia enabled successful anesthesia management without the development of either pulmonary hypertension or right heart failure. Conclusion: Spinal anesthesia combined with epidural analgesia is a useful anesthetic method for a Cesarean section in patients with unilateral absence of a pulmonary artery.

Resumo Justificativa e objetivos: A ausência congênita unilateral de uma artéria pulmonar (ACAP) é uma anomalia rara. Embora existam vários relatos sobre pacientes grávidas com ACAP, não há relatos de casos que descrevam anestesia para cesariana em pacientes com ACAP. Relato de caso: Apresentamos uma paciente com ACAP que foi submetida a duas cesarianas, aos 24 e 26 anos, sob raquianestesia para a cirurgia e analgesia epidural para a dor no pós-operatório. Nas duas cesarianas, a raquianestesia e a analgesia epidural possibilitaram o manejo bem-sucedido da anestesia, sem a ocorrência de qualquer hipertensão pulmonar ou insuficiência cardíaca direita. Conclusão: Raquianestesia combinada com analgesia epidural é um método anestésico útil para cesarianas em pacientes com ACAP.

Tasa de cesáreas por grupos de Robson en una institución de mediana complejidad de la ciudad de Bogotá, 2012-2014 / Cesarean section rate by Robson groups in an intermediate complexity centre in the city of Bogotá, 2012-2014

Introducción: la clasificación de Robson permite caracterizar las mujeres a las que se les realiza cesárea con el fin de implementar estrategias focalizadas con éxito. El objetivo fue determinar las tasas específicas de cesárea según la clasificación de Robson en una institución hospitalaria de mediana complejidad. Materiales y métodos: estudio descriptivo transversal que incluyó mujeres atendidas en un hospital público de atención general, que recibe pacientes del aseguramiento subsidiado por el Estado, entre 2012 y 2014. Se llevó a cabo muestreo aleatorio estratificado según la vía del parto, basado en la razón parto/cesárea encontrada en el periodo, clasificando las mujeres atendidas en los 10 grupos de Robson. Se realizó el análisis descriptivo de las variables demográficas, indicaciones clínicas reportadas y las proporciones global y específica de uso de cesárea en cada grupo. El estudio contó con aprobación del comité de ética institucional. Resultados: se seleccionaron 1.190 de 6.558 nacimientos ocurridos durante el periodo. La proporción global de cesárea fue de 36,9 %. Las mujeres nulíparas contribuyeron con el 38,5 % de las cesáreas, seguidas por el grupo con cesárea anterior (36,4 %) que tuvo una proporción específica del 100 %. La proporción específica de cesárea en el grupo de mujeres nulíparas en trabajo de parto espontáneo fue 36,6 % y la del grupo de partos prematuros 43,3 %. Conclusiones: las mujeres con cesárea anterior, con embarazo pretérmino y las nulíparas en parto espontáneo o inducido tienen las proporciones específicas más elevadas de cesárea. Estos grupos podrían ser susceptibles de intervención para impactar las tasas de cesárea de la institución.

Introduction: The Robson classification is useful for characterizing women taken to Cesarean section with the aim of implementing successful focused strategies. The objective was to determine specific Cesarean section rates according to the Robson classification in an intermediate complexity hospital. Materials and methods: cross-sectional descriptive study that included women of the state-subsidized health insurance regime seen at a general public hospital between 2012 and 2014. A stratified random sampling was performed on the basis of the birth route, per delivery, based on the delivery/Cesarean section ratio found during the time period. The women were classified under 10 Robson groups. A descriptive analysis was conducted of the demographic variables, the clinical indications reported, and the overall and specific proportions of Cesarean sections in each group. The study was approved by the Ethics Committee of the Institution. Results: Out of 6558 deliveries during the study period, 1190 were selected. The overall proportion of Cesarean sections was 36.9%. Nulliparous women accounted for 38.5% of the Cesarean sections, followed by the group with previous Cesarean sections (36.4%) for which the specific proportion was 100%. The specific proportion of Cesarean sections in nulliparous women in spontaneous labour was 36.6%, whereas it was 43.3% in the premature delivery group. Conclusions: The highest specific proportions of Cesarean section were found among women with a previous Cesarean section, women with pre-term delivery and nulliparous women with spontaneous or induced delivery. These groups could lend themselves for intervention in order to have an impact on the rates of Cesarean section in the Institution.

Caesarean section surgical techniques (CORONIS): a fractional, factorial, unmasked, randomised controlled trial.

BACKGROUND: Variations exist in the surgical techniques used for caesarean section and many have not been rigorously assessed in randomised controlled trials. We aimed to assess whether any surgical techniques were associated with improved outcomes for women and babies. METHODS: CORONIS was a pragmatic international 2×2×2×2×2 non-regular fractional, factorial, unmasked, randomised controlled trial that examined five elements of the caesarean section technique in intervention pairs. CORONIS was undertaken at 19 sites in Argentina, Chile, Ghana, India, Kenya, Pakistan, and Sudan. Each site was assigned to three of the five intervention pairs: blunt versus sharp abdominal entry; exteriorisation of the uterus for repair versus intra-abdominal repair; single-layer versus double-layer closure of the uterus; closure versus non-closure of the peritoneum (pelvic and parietal); and chromic catgut versus polyglactin-910 for uterine repair. Pregnant women were eligible if they were to undergo their first or second caesarean section through a planned transverse abdominal incision. Women were randomly assigned by a secure web-based number allocation system to one intervention from each of the three assigned pairs. All investigators, surgeons, and participants were unmasked to treatment allocation. The primary outcome was the composite of death, maternal infectious morbidity, further operative procedures, or blood transfusion (>1 unit) up to the 6-week follow-up visit. Women were analysed in the groups into which they were allocated. The CORONIS Trial is registered with Current Controlled Trials: ISRCTN31089967. FINDINGS: Between May 20, 2007, and Dec 31, 2010, 15 935 women were recruited. There were no statistically significant differences within any of the intervention pairs for the primary outcome: blunt versus sharp entry risk ratio 1·03 (95% CI 0·91-1·17), exterior versus intra-abdominal repair 0·96 (0·84-1·08), single-layer versus double-layer closure 0·96 (0·85-1·08), closure versus non-closure 1·06 (0·94-1·20), and chromic catgut versus polyglactin-910 0·90 (0·78-1·04). 144 serious adverse events were reported, of which 26 were possibly related to the intervention. Most of the reported serious adverse events were known complications of surgery or complications of the reasons for the caesarean section. INTERPRETATION: These findings suggest that any of these surgical techniques is acceptable. However, longer-term follow-up is needed to assess whether the absence of evidence of short-term effects will translate into an absence of long-term effects.

[Rates of caesarean sections tn two types of private hospitals: restriced-access and open-access]. / Tasa de cesáreas en dos hospitales privados con normativas diferentes: abierto y cerrado.

BACKGROUND: In recent years, rising rates of caesarean section are of concern in the medical community in many countries, especially in Latin America. OBJECTIVE: Determine if there is a difference in the rate of Caesarean sections in a restricted-access hospital (HC) and an open-access hospital (HA) using the Robson classification to explain potential differences. MATERIAL AND METHOD: A prospective cohort study was conducted. This in volved all patients that attended the obstetrics sector in the two hospitals in Buenos Aires where they gave birth between 1 June 2009 and 25h January 2010. The open-access hospital is open to doctors with varying professional training and differing clinical practice. The restricted-access hospital, on the other hand, can only be attended by specified doctors with certain professional training; their medical) conduct is based on service standards and clinical practice. RESULTS: Over the study period 762 patients who fulfilled the study criteria were included from the open-access hospital and 768 from the restricted-access hospital. The global rate of caesarean sections in the HAwas 53.5%, and 48.7% in the HC, RR 1.09 (CI 0.99-1.21) a difference that was not statistically significant (p = 0.058). The onset of spontaneous labour in the HAwas significantly more than in the HC (74.9% vs. 41.8%) RR 2.66 (CU.98-3.57). The induced labour was significantly lower in HA (9,7% vs. 28,3%); RR 0.34 (CI 0.27-0.44). Elective caesarean sections were significantly lower in the HA (15.3% vs. 29.9%) RR 0.51 (CI 0.42-0.62). CONCLUSION: This study reveals a similar rate of caesarean sections in two private hospitals with different systems of care. However, it observed that the HA has a greater tendency to operate on patients at the onset of spontaneous labour and the HC has a greater number of induced labour and elective caesarean section.

[Ectopic pregnancy in cesarean scar]. / Embarazo ectópico en cicatriz de cesárea previa.

The ectopic pregnancy within a cesarean scar, is defined as the implantation of the blastocyst outside the endometrium in the site where the histerotomy was made in the previous cesarean. We report a case of a 35-year-old patient, which arrives to the emergency room with 11.3 weeks of gestation. With the diagnostic, prognostic and pleased parity we decide to do block hysterectomy. We describe this case because of its low frequency, but catastrophic consequences that put on danger mothers life. Prevalence is calculated on 1:1800-1226 of all pregnancies (0.15%) and represents 6.15% of de ectopic pregnancies in women with at least one cesarean. They have been published a mayor number of cases during the last decade, probably because of the world increment of cesarean delivery or the earliest diagnostic. We recommend interruption of pregnancy at the moment of diagnosis, to avoid complications.

[Cesarean birth: justifying indication or justified concern?]. / Operación cesárea: Indicación justificante o preocupación justificada?

BACKGROUND: Caesarean section is the most common surgery performed in all hospitals of second level of care in the health sector and more frequently in private hospitals in Mexico. OBJECTIVE: To determine the behavior that caesarean section in different hospitals in the health sector in the city of Aguascalientes and analyze the indications during the same period. MATERIAL AND METHOD: A descriptive and cross in the top four secondary hospitals in the health sector of the state of Aguascalientes, which together account for 81% of obstetric care in the state, from 1 September to 31 October 2008. Were analyzed: indication of cesarean section and their classification, previous pregnancies, marital status, gestational age, weight and minute Apgar newborn and given birth control during the event. RESULTS: were recorded during the study period, 2.964 pregnancies after 29 weeks, of whom 1.195 were resolved by Caesarean section with an overall rate of 40.3%. We found 45 different indications, which undoubtedly reflect the great diversity of views on the institutional medical staff to schedule a cesarean section. CONCLUSIONS: Although each institution has different resources and a population with different characteristics, treatment protocols should be developed by staff of each hospital to have the test as a cornerstone of labor, also request a second opinion before a caesarean section, all try to reduce the frequency of cesarean section.
