Retrospective analysis of associated factors and adverse pregnancy outcomes of postpartum hemorrhage in the caesarean section of different types of placenta previa / 中华预防医学杂志

Objective: To analyze associated factors and adverse pregnancy outcomes of postpartum hemorrhage in the caesarean section of puerperae with different types of placenta previa. Methods: This retrospective research was a case-control study. Puerperae with cesarean section of placenta previa from January 2019 to December 2020 in Women's Hospital, School of Medicine, Zhejiang University were collected and divided into the<1 000 ml control group or ≥1 000 ml postpartum hemorrhage group according to the amount of blood loss during cesarean section. Differences in continuous variables were analyzed by t-test and categorical variables were analyzed by χ2 test. The risk factors of postpartum hemorrhage were analyzed by logistic multivariate regression. Results: A total of 962 puerperae were enrolled with 773 cases in the control group and 189 cases in the postpartum hemorrhage group. The incidence of gestational weeks, gravidity, parity, induced abortion, placental accreta and preoperative hemoglobin<110 g/L was significantly different between two groups in different types of placenta previa (P<0.001). Logistic multivariate regression model analysis showed that the independent risk factors of postpartum hemorrhage in the caesarean section of low-lying placenta included placental accreta (OR=12.713, 95%CI: 4.296-37.625), preoperative hemoglobin<110 g/L (OR=2.377, 95%CI: 1.062-5.321), and prenatal vaginal bleeding (OR=4.244, 95%CI: 1.865-9.656). The independent risk factors of postpartum hemorrhage in the caesarean section of placenta previa included once induced abortion (OR=2.789, 95%CI:1.189-6.544), induced abortion≥2 (OR=2.843, 95%CI:1.101-7.339), placental accreta (OR=6.079, 95%CI:3.697-9.996), HBsAg positive (OR=3.891, 95%CI:1.385-10.929), and placental attachment to the anterior uterine wall (OR=2.307, 95%CI:1.285-4.142). The rate of postpartum hemorrhage and premature delivery in puerperae with placenta previa was higher than that in puerperae with low-lying placenta (P<0.001). Conclusions: The associated factors of postpartum hemorrhage in puerperae with different types of placenta previa are different. Placenta accreta is the common risk factor of postpartum hemorrhage in puerperae with low-lying placenta and placenta previa.

Clinical Experience Over 15 Years with the B-Lynch Compression Suture Technique in the Management of Postpartum Hemorrhage / Experiência clínica ao longo de 15 anos com a técnica de sutura compressiva de B-Lynch no manejo da hemorragia pós-parto

Abstract Objective To describe the clinical experience with the B-Lynch technique in the management of postpartum hemorrhage as well as the factors related to the indication of the technique and to present the success rates of the application of the B-Lynch technique. Methods Observational, retrospective, cross-sectional, and analytical study. Patient data was obtained through the study of medical records. The study population comprised of patients who underwent hemostatic suture using the B-Lynch technique, including 104 patients within the period from January 1, 2005, to December 31, 2019. Results Of the total of 104 patients, 82.7% did not present any complications. Blood transfusion and intensive care unit admission were the most prevalent complications, with 13.5% and 15.4%, respectively. Only 1% of the patients had puerperal and surgical site infections. The factors most related to the application of the technique were the presence of previous cesarean section (30.8%), use of oxytocin (16.3%), and pre-eclampsia (11.6%). Puerperal hysterectomy was performed in 4.8% of the patients due to failure of the method. Conclusion The clinical experience with the B-Lynch technique was satisfactory since it presented few complications, with excellent results in hemorrhagic control. Previous cesarean section, the use of oxytocin, and preeclampsia stood out as factors related to the indication of the application of the technique, and the success rate in controlling postpartum hemorrhage was 95.2%.

Peripartum Hysterectomies over a Fifteen-year Period / Histerectomias periparto ao longo de um período de quinze anos

Abstract Objective To determine the indications and outcomes of peripartum hysterectomies performed at Hospital de Clínicas de Porto Alegre (a university hospital in Southern Brazil) during the past 15 years, and to analyze the clinical characteristics of the women submitted to this procedure. Methods A cross-sectional study of 47 peripartum hysterectomies from 2005 to 2019. Results The peripartum hysterectomies performed in our hospital were indicated mainly due to placenta accreta or suspicion thereof (44.7% of the cases), puerperal hemorrhage without placenta accreta (27.7%), and infection (25.5%). Total hysterectomies accounted for 63.8% of the cases, andwefound no differencebetween total versus subtotal hysterectomies in the studied outcomes. Most hysterectomies were performed within 24 hours after delivery, and they were associated with placenta accreta, placenta previa, and older maternal age. Conclusion Most (66.0%) patients were admitted to the intensive care unit (ICU). Those who did not need it were significantly older, and had more placenta accreta, placenta previa, or previous Cesarean delivery.

Resumo Objetivo Determinar as indicações e os desfechos das histerectomias periparto realizadas no Hospital de Clínicas de Porto Alegre nos últimos 15 anos, bem como analisar as características clínicas das mulheres submetidas a esse procedimento. Métodos Estudo transversal de 47 histerectomias periparto realizadas no período de 2005 a 2019. Resultados Em nosso hospital, as histerectomias periparto foram indicadas principalmente por acretismo placentário ou sua suspeita (44,7% dos casos), hemorragia puerperal sem acretismo placentário (27,7%), e infecção (25,5%). Histerectomias totais corresponderam a 63,8% dos casos, e não encontramos diferença entre histerectomia total e subtotal para os desfechos estudados. Amaioria das histerectomias foi realizada dentro de 24 horas após o parto, o que estava associado a acretismo placentário, placenta prévia, e idade materna mais avançada. Conclusão A maioria (66,0%) das mulheres necessitou de internação em unidade de terapia intensiva (UTI); aquelas que não necessitaram eram significativamente mais velhas, e tinham mais acretismo placentário, placenta prévia, ou cesárea prévia.

Ligaduras vasculares no tratamento cirúrgico da hemorragia pós-parto / Vascular ligations in the surgical treatment of postpartum hemorrhage

Hemorragia pós-parto é a maior causa de histerectomia periparto. Esta revisão descreve e ilustra as técnicas de ligaduras vasculares utilizadas no tratamento cirúrgico da hemorragia pós-parto. São apresentados os detalhes técnicos da ligadura das artérias uterinas, da ligadura das conexões útero-ovarianas, da ligadura tríplice de Tsirulnikov, das ligaduras sequenciais de AbdRabbo e de Morel e da ligadura das artérias ilíacas internas.

The factors that hinder the success of these techniques also are reviewed. Vascular ligations are efficient strategies for hemorrhagic control during cesarean sections and should integrate the set of techniques that preserve the uterus in the treatment of postpartum hemorrhage.(AU)

Embarazo posterior a cirugía conservadora del útero ante hemorragia obstétrica postparto. Presentación de un caso / Pregnancy after conservative surgery of the uterus after postpartum obstetric hemorrhage. Presentation of a case

RESUMEN El embarazo es un proceso natural que debe concebirse sin complicaciones; sin embargo, los desenlaces obstétricos fatales en gestaciones previas, son marcadores importantes de un riesgo incrementado de morbimortalidad materna y perinatal en los próximos embarazos. La hemorragia obstétrica posparto es una de las más frecuentes y severas complicaciones del periparto; como una alternativa terapéutica útil en esos casos, el manejo quirúrgico conservador de útero permite mantener la fertilidad en mujeres con paridad no satisfecha, y mejorar su calidad de vida, aunque en muchas ocasiones, por causas diversas, esto no es posible. Se presenta el caso de una paciente de 26 años de edad, con historia obstétrica de tres embarazos, un parto y un aborto (provocado); y el antecedente de complicación obstétrica hemorrágica en embarazo anterior por atonía uterina, la cual requirió tratamiento quirúrgico conservador con técnicas combinadas (suturas compresivas de Hayman, Ho-Cho y ligadura bilateral de las arterias uterinas). Dos años después, acudió a los servicios obstétricos con gestación de 16 semanas (alto riesgo obstétrico). Este artículo tiene el objetivo de exponer el informe de una paciente en la que se logró la concepción de un embarazo posterior a la realización de cirugía conservadora del útero.

ABSTRACT Pregnancy is a natural process that must be conceived without complications; however, fatal obstetric outcomes in previous pregnancies are important markers of an increased risk of maternal and perinatal morbidity and mortality in future pregnancies. Postpartum obstetric hemorrhage is one of the most frequent and severe complications of the peripartum; As a useful therapeutic alternative in these cases, conservative surgical management of the uterus allows fertility to be maintained in women with unsatisfied parity, and improves their quality of life, although in many cases, for various reasons, this is not possible. The case of a 26-year-old patient is presented, with an obstetric history of three pregnancies, one delivery and one abortion (provoked); and a history of hemorrhagic obstetric complication in previous pregnancy due to uterine atony, which required conservative surgical treatment with combined techniques (Hayman, Ho-Cho compression sutures and bilateral ligation of the uterine arteries). Two years later, she attended obstetric services with a 16-week gestation (high obstetric risk). This article aims to present the report of a patient in whom the conception of a pregnancy was achieved after performing conservative surgery on the uterus.

Experiencia de un centro colombiano en el tratamiento endovascular de la hemorragia posparto que amenaza la vida / Experience of a Colombian center in the endovascular management of life-threatening postpartum hemorrhage

Resumen Introducción. La hemorragia posparto es la primera causa de morbimortalidad materna en el mundo y las laceraciones son la segunda causa en frecuencia. Su tratamiento temprano y apropiado es clave para obtener buenos resultados, y la oclusión endovascular de los vasos pélvicos se cuenta entre las opciones terapéuticas. Objetivo. Describir la experiencia del tratamiento con la 'embolización' (sic) arterial de los vasos pélvicos. Materiales y métodos. Se trató de un estudio retrospectivo del tipo de serie de casos basado en el registro institucional de la Fundación Valle del Lili, Cali, Colombia, en el que se incluyeron las pacientes con hemorragia posparto atendidas entre el 1º de enero del 2011 y el 31 de octubre del 2016. Resultados. De las 430 pacientes con diagnóstico de hemorragia posparto, 11 fueron sometidas a la 'embolización' de los vasos pélvicos. De este grupo, 10 pacientes tuvieron parto vaginal con laceraciones vaginales complejas, y la mayoría (9 casos, 82 %) fue remitida por otras instituciones de menor complejidad después de 20,5 horas. Las arterias ocluidas frecuentemente fueron la vaginal superior y la pudenda interna. Ninguna paciente presentó complicaciones asociadas al procedimiento y solo dos presentaron sangrado recurrente. Tres pacientes requirieron histerectomía y ninguna murió. Conclusión. El manejo percutáneo es un método de tercera línea, seguro y efectivo para el control de los sangrados de difícil manejo en las pacientes con hemorragia posparto por desgarros perineales complejos. Estos resultados son similares a los reportados en la literatura científica mundial disponible hasta la fecha.

Abstract Introduction: Postpartum hemorrhage is a world-leading cause of morbidity and mortality. Lacerations are the second most frequent cause. Early management with appropriate treatment is essential to obtain adequate outcomes; the endovascular occlusion of pelvic vessels is among the management options. Objective: To describe the management experience with the arterial embolization of pelvic vessels. Materials and methods: We conducted a retrospective case series study based on the institutional registry of Fundación Valle del Lili (Cali, Colombia), which included patients with postpartum hemorrhage admitted between January 1st, 2011 and October 31st, 2016. Results: Out of 430 patients diagnosed with PPH, 11 were subject to embolization of pelvic vessels. Within our group, 10 patients had a vaginal delivery with severe vaginal lacerations; most of them (9 cases, 82%) were referred from other lower-complexity institutions after 20.5 hours. Occlusion was more frequent in the superior vaginal and the internal pudendal arteries. No patients showed complications associated with the procedure and only 2 showed recurrent bleeding while 3 required a hysterectomy, but no deaths occurred. Conclusion: Percutaneous management is a safe and effective third-line method for difficult-management bleedings control in patients with postpartum hemorrhage after a severe perineal tear. These results are similar to case reports published in the worldwide literature available to date.

Embolização de artéria uterina para hemorragia pós-parto: uma revisão de literatura / Uterine artery embolization for postpartum hemorrhage: a review of the literature

A hemorragia pós-parto é uma emergência obstétrica que acomete grande parcela de puérperas e leva à extensa quantidade de óbitos por ano. Entre as suas principais causas estão a atonia uterina e o acretismo placentário. Atualmente, as técnicas mais utilizadas para a resolução do sangramento se apresentam por muitas vezes ineficazes e/ou levam à infertilidade feminina. O presente estudo trata-se de uma revisão da literatura em modelo PRISMA, no qual foram selecionados 35 artigos dos últimos 12 anos, nas bases de dados do UpToDate, SciELO, PubMed, Plos ONE, Lilacs e Datasus, no qual serão apresentadas evidências de que, nas mãos de um profissional treinado, a embolização de artéria uterina se mostra como uma excelente alternativa no tratamento da hemorragia obstétrica, apresentando-se como terapêutica minimamente invasiva, com altas taxas de sucesso, baixo número de complicações e que preserva a função reprodutiva da mulher.(AU)

The post-partum hemorrhage is an obstetric emergency that affects a big percentage of women who have recently given birth and leads to a big amount of deaths per year. Its main causes are uterine atony and placentary accretism. Currently the main techniques for its resolution are the utilization of uterotonics and aggressive surgical approaches to the pelvic structure, which are commonly inefficient or bring long term injuries to the fertility. This study is a literature review structure on PRISMA model, where was selected 35 articles of the last 12 years, in these databases: UpToDate, SciELO, PubMed, Plos ONE, Lilacs and Datasus, in which will be presented evidences of, in expert professional hands, uterine artery embolization being an excellent alternative in the treatment of obstetric hemorrhage, presenting itself a minimally invasive technique, with high rates of success, low numbers of complications and the capacity of preserving the patient reproductive system.(AU)

Modified pereira suture as an effective option to treat postpartum hemorrhage due to uterine atony / Sutura de Pereira modificada como uma opção eficaz para tratar a hemorragia causada por atonia uterina

Abstract Nowadays, postpartum hemorrhage is the major cause of maternal mortality and morbidity worldwide. Uterine atony is its main cause; thus, prophylactic measures, as well as medical and surgical fast approaches, have been developed to manage it. The uterine compression sutures are a possible treatment that preserves the uterus and, consequently, the fertility potential. Bearing that in mind, we report two cases of postpartum hemorrhage after caesarean section, successfully treated with a new modification of Pereira suture - longitudinal and transverse uterine sutures were applied after no response was registered to the first-line therapies. Both women recovered, and the postpartum evaluation revealed a normal uterus with an adequate blood supply, suggesting potential fertility, as described in the literature regarding this kind of therapeutic approach.

Resumo Atualmente, a hemorragia pós-parto é a maior causa de morbimortalidadematerna em todo o mundo. Sua principal causa é a atonia uterina, pelo que têm sido instituídas e desenvolvidas medidas profiláticas, bem como tratamentos médicos e cirúrgicos para esta complicação. As suturas uterinas de compressão representam uma possibilidade terapêutica que permite a preservação do útero e, por conseguinte, do potencial fértil. Tendo isso por base, apresentamos dois casos de hemorragia pós-parto após cesariana, que foram tratados com sucesso com uma nova modificação da sutura de Pereira - suturas uterinas longitudinais e transversais foram efetuadas após falha das terapias de primeira linha. Ambas as pacientes se recuperaram, e na reavaliação pós-parto objetivou-se um útero normal com manutenção de uma irrigação adequada, sugerindo a preservação do seu potencial fértil, tal como vem sendo descrito na literatura em relação a este tipo de procedimento.

Sutura de B-Lynch en hemorragia postparto por inercia uterina: experiencia Hospital Dr. Luis Tisné Brousse 2013-2016 / B-Lynch suture in postpartum hemorrhage due to uterine inertia: Hospital Experience Dr. Luis Tisné Brousse 2013-2016

INTRODUCCIÓN Y OBJETIVOS: La Hemorragia Postparto (HPP) es uno de los grandes desafíos para el equipo multidisciplinario y sigue siendo una de las principales causas de muerte materna en el mundo, pese a los adelantos en su manejo. Se define como la hemorragia que produce compromise hemodinámico de la paciente e involucra entre el 1 al 5% de todos los partos. Dentro de las técnicas quirúrgicas conservadoras, existen las suturas compresivas, tales como la sutura de B-Lynch. Nuestro objetivo es determinar la efectividad de la sutura de B-Lynch como manejo quirúrgico conservador de hemorragia postparto por inercia uterina, a través de la necesidad de reintervención o de recurrir a la histerectomía obstétrica como manejo quirúrgico final. MÉTODOS: Estudio retrospectivo observacional, a través de revisión de fichas clínicas de pacientes sometidas a técnica B-Lynch entre enero de 2013 y diciembre de 2016, en el Servicio de Ginecología y Obstetricia del Hospital Dr. Luis Tisné Brousse. RESULTADOS: En 48 pacientes, la efectividad de la sutura de B-Lynch como técnica única o asociada a ligadura arterias uterinas o hipogástricas fue de 91,7%. Requirieron reintervención 8,3%, no se reportaron muertes fetales ni maternas y se obtuvo sólo un recién nacido con Apgar inferior a 7 a los 5 minutos. CONCLUSIONES: La sutura de B-Lynch es una técnica segura, de rápido acceso y con Buenos resultados, por lo que recomendamos su uso en la HPP por inercia uterina que no responde a manejo médico y con deseos de preservación uterina.

INTRODUCTION AND OBJECTIVES: Postpartum haemorrhage (HPP) is one of the major challenges for the multidisciplinary team and remains one of the leading causes of maternal death in the world despite advances in its management. It is defined as hemorrhage that produces hemodynamic compromise of the patient and involves between 1 and 5% of all deliveries. Within conservative surgical techniques, there are compressive sutures, such as the B-Lynch suture. Our goal is to determine the effectiveness of B-Lynch suture as a conservative surgical management of postpartum hemorrhage by uterine inertia, through the need for reoperation or to resort to obstetric hysterectomy as final surgical management. METHODS: Retrospective observational study, through review of clinical files of patients submitted to B-Lynch technique between January 2013 and December 2016, at the Gynecology and Obstetrics Service of the Dr. Luis Tisné Brousse Hospital. RESULTS: In 48 patients, the effectiveness of the B-Lynch suture as a single technique or associated with ligature uterine or hypogastric arteries was 91.7%. 8.3% were reoperated, fetal or maternal deaths were not reported, and only one Apgar score was less than 7 at 5 minutes. CONCLUSIONS: The B-Lynch suture is a safe technique, of fast access and good results, so we recommend its use in PPH by uterine inertia that does not respond to medical management and with desires of uterine preservation.

Los resultados indicaron que el parto por cesárea ha presentado tasa de 37,2%, la amniotomía fue adoptada en 62,1%, la oxitocina en 53,4% y la episiotomía en 82,4%. La desproporción cefalopélvica ha representado 27,9% de las indicaciones de la cesárea y entre las complicaciones maternas, la hemorragia se ha destacado en ambos tipos de parto. Se concluye que existe una fuerte influencia del modelo técnico sobre los resultados maternos en la atención obstétrica a las adolescentes primigestas y que el hecho del desconocimiento relacionado a la vulnerabilidad de este grupo poblacional evidencia la soberanía del profesional en relación a las decisiones obstétricas.

ABSTRACT It aimed to analyze labor assistance for primigravida adolescents in the context of the Unified Health System (SUS) in the city of Cuiabá, Mato Grosso. Cross-sectional, descriptive and documental study with a random sample composed of 164 medical records of postpartum adolescent collected through structured file during the months of December 2012 to May 2013. Data were analyzed through simple descriptive analysis. The results indicated that cesarean section showed rate of 37.2%, amniotomy was adopted in 62.1%, oxytocin 53.4% and 82.4% in the episiotomy. Cephalopelvic disproportion represented 27.9% of cesarean section indications and among maternal complications, hemorrhage stood out in both types of delivery. It is concluded that there is a strong influence of the technicist model on maternal outcomes in obstetric care to pregnant adolescents and that the lack of knowledge linked to the vulnerability of this group shows the professional sovereignty in relation to obstetric decisions.

Uso de suturas uterinas compressivas na hemorragia pós-parto / Use of uterine compression sutures in postpartum hemorrhage

A hemorragia pós-parto é uma complicação presente em mais de 18% dos nascimentos e é responsável por cerca de 25 a 30% das mortes maternas no mundo. Nas últimas décadas, várias técnicas conservadoras visando o controle hemorrágico no período pós-parto têm sido relatadas, com destaque para as ligaduras vasculares, suturas uterinas compressivas, embolização arterial, balões intrauterinos e a interrupção do ato operatório com laparostomia, empacotamento pélvico e posterior abordagem cirúrgica. O presente artigo apresenta uma revisão das suturas uterinas compressivas, com destaque para a cronologia de criação das técnicas de execução, e as publicações em periódicos. São descritas as suturas de Schnarwyler, B-Lynch, Cho, Hayman, Bhal, Pereira, Ouabha, Hackethal, Meydanli, Marasinghe-Condous, Matsubara-Yano, Zheng e a técnica de Halder. Foram detalhadas também as indicações, as técnicas associadas e as complicações.(AU)

Postpartum hemorrhage is present in over 18% of births and accounts for 25 to 30% of maternal deaths worldwide. In the last decades, several conservative techniques direct at controlling hemorrhage in the postpartum period have been reported, principally vascular ligatures, uterine compression sutures, arterial embolization, intrauterine balloons and surgery interruption with laparostomy, pelvic packing and subsequent surgical intervention. This article presents a review of uterine compression sutures, especially the chronology of creation of the execution techniques and publications in journals. Schnarwyler, B-Lynch, Cho, Hayman, Bhal, Pereira, Ouabha, Hackethal, Meydanli, Marasinghe-Condous, Matsubara-Yano, Zheng and Halder sutures were reviewed. Indications, associated techniques and complications were also detailed.(AU)

Uterine artery embolization for primary postpartum hemorrhage

Postpartum hemorrhage is the leading cause of severe maternal morbidity and death. A prompt management of uterine artery embolization [UAE] is important for a good outcome. UAE is generally accepted to be a safe and reliable procedure. To estimate critical patient characteristics influencing the success of UAE for the treatment of emergent primary postpartum hemorrhage. This was a cross sectional study that reviewed 121 patients who were diagnosed primary postpartum hemorrhage between February 2002 and December 2009 at a tertiary treatment center among 4,022 deliveries. We evaluated patient clinical characteristics associated with a successful surgical outcome of UAE. The success rate for UAE was 96%. For two cases, UAE complication was associated with fever [>38.5°C]. Five patients had problems that required admission to the intensive care unit [ICU]. To increase the surgical success rate and lower the number of ICU admissions, the decision to treat primary postpartum hemorrhage using UAE should be based on individual patient clinical findings under the direction of obstetrics staff and an interventional radiologist

Introdução: As síndromes hemorrágicas estão entre as principais causas obstétricas diretas de mortes maternas. Segundo dados da Organização Mundial de Saúde estima-se uma morte a cada quatro minutos. A hemorragia pós-parto reflete diretamente a qualidade da assistência, sendo uma das causas potencialmente prevenível e tratável. O desenvolvimento de manejos clínicos para seu controle torna-se de extrema importância na redução da mortalidade materna. Objetivo: Definir a melhor estratégia para a prevenção e o tratamento da hemorragia pós-parto, enfatizando o manejo ativo no terceiro estágio do trabalho de parto. Métodos: Foi realizada uma revisão de literatura no banco de dados Medline/PubMed, LILACS/SciELO, Cochrane Library e no site do Royal College of Obstetricians and Gynaecologists em busca das melhores evidências clínicas disponíveis, considerando-se o grau de recomendação. Resultados: Verificou-se que o manejo ativo da terceira fase do trabalho de parto é de fundamental importância para a prevenção da hemorragia pós-parto. O uso de uterotônicos, sendo a ocitocina o fármaco de primeira linha para este fim, a tração controlada de cordão umbilical com massagem uterina são a base deste tratamento. O tratamento cirúrgico também pode ser necessário e deve ter uma indicação precisa e de acordo com a experiência do cirurgião. Conclusão: Uma boa assistência a gestantes durante o trabalho de parto, principalmente uma conduta ativa no terceiro estágio, interfere de forma positiva para a prevenção de hemorragias maternas graves, contribuindo para o controle e diminuição da mortalidade materna.(AU)

Introduction: The haemorrhagic syndromes are the main causes of direct obstetric maternal deaths. According to data from the World Health Organization estimated one death every four minutes. Postpartum haemorrhage directly reflects the quality of care, being a potentially preventable and treatable causes. The development of clinical managements to their control it becomes of extremely important for reduction maternal mortality. Objective: The aim of this work was to search in literature the most important strategy to prevent and the treat the postpartum haemorrhage, emphaesing the active management in the third stage of labour. Methods: A revision of literature in the Medline/ PubMed, LILACS/ SciELO, Cochrane Library and in the site of the Royal College of Obstetricians and Gynaecologists data base was carried through, in search of the best clinical evidences available, take into account also the degree of recommendation. Results: It was founded that the active management of third stage of labour is fundamental for prevention of postpartum hemorrhage. The oxytocin was first line drug for this effect, the control umbilical lace traction with uterine massage is the base of this treatment. The surgery can be necessary and must have a straight indication and the experience of surgeon has a lot of importance. Conclusion: A good care for pregnant women during the labour, mainly in the active third stage of labour interferes in a positive way to prevent severe mothers' haemorrhages, and contributes to the reduction of maternal mortality.(AU)

beta-lynch suture for the management of postpartum haemorrhage: an experience at Peoples Medical College Hospital

To report our clinical experience of the effectiveness and safety of applying beta-lynch suture for the management of primary postpartum haemorrhage. An observational, cross-sectional study. This study was conducted at the Department of Obstetrics and Gynaecology at Peoples Medical College Hospital Nawabshah from 1[st] January 2009 to 30 [th] June 2010. All the patients of primary postpartum haemorrhage in whom compression and conventional ecobolic had failed to achieve uterine contraction and haemostasis were subjected to beta-lynch suture. beta-lynch suture technique was applied in 33 patients, in 22 patients after vaginal delivery and in 11 patients at the time of cesarean section. This technique was successful in 31 [93.94%] patients and failed in only 2 [6.1%]. Patients who were proceeded to hysterectomy, none of the patient had infection. beta-lynch suture compresses and envelopes the uterus and manages massive life threatening postpartum haemorrhage successfully. It is effective, simple and fertility conserving procedure

[Ligation of internal iliac arteries for sever hemorrhage in obstetric]

To assess the efficiency of arteries ligation in intractable obstetrical hemorrhage. Prospective study which concerned 53 patients who underwent internal iliac arteries ligation for persistent and severe obstetrical hemorrhage from January 2007 to June 2010. The average age of patients was 29.3 years. The mean parity was 2.2. Main etiology of hemorrhage were: uterine atony [62.2%], abruptio placentae [15.1%]. Coagulation disorders and hypovolemic shock were observed respectively in 20.7% and 37.7%. Blood transfusion was performed in all cases. Internal iliac arteries ligation allowed hemorrhage control in 90.5% of cases. In five cases a hysterectomy was necessary to control bleeding.. No peroperative complication were observed.

La placenta percreta es una rara enfermedad placentaria, con una incidencia muy baja y un muy difícil diagnóstico prenatal. Se presentan tres casos clínicos de placenta percreta recogidos en nuestro centro en los últimos 20 años. Se realiza una exposición detallada de cada uno de ellos, atendiendo fundamentalmente a la secuencia de acontecimientos quirúrgicos que tienen lugar tras el diagnóstico de esta grave entidad. La dificultad en el diagnóstico prenatal, así como la imperiosidad de las medidas terapéuticas, convierten a la placenta percreta en una enfermedad con una elevada morbilidad y mortalidad materna. El tratamiento quirúrgico así como la prevención y el tratamiento de la hemorragia posparto son las armas fundamentales para controlar esta gravísima complicación obstétrica.

The placenta percreta is a rare placental disease with a very low incidence and prenatal diagnosis difficult. We present three cases of placenta percreta observed in our hospital over the past 20 years. We present a detailed discussion of each of them, fundamentally to the sequence of surgical events that occur after the diagnosis of this serious entity. The difficulty of prenatal diagnosis, as well as the urgent therapeutic measures, make the placenta percreta in a disease with high morbidity and mortality. The surgical treatment and the prevention of postpartum hemorrhage are essential weapons to control this serious obstetric complication.
