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.

Analysis of Variables that Influence the Success Rates of Induction of Labor with Misoprostol: A Retrospective Observational Study / Análise de variáveis que influenciam na taxa de sucesso da indução do parto com misoprostol: Um estudo observacional retrospectivo

Abstract Objective Determine the predictive criteria for success in inducing labor for live fetuses using misoprostol in pregnant women. Secondarily, the objective is to determine the rates of vaginal or cesarean delivery, duration of induction, interval of administration of misoprostol, the main causes of induction of labor and indication for operative delivery. Methods Medical records of 873 pregnant women admitted for cervical maturation from January 2017 to December 2018 were reviewed in a descriptive observational study of retrospective analysis, considering the following response variables: age, parity, Bishop Index, doses of misoprostol, labor induction time. Logistic regression models were used to predict success with misoprostol in non-operative deliveries. Results Of the 873 patients evaluated, 72% evolved with vaginal delivery, 23% of the cases were cesarean, 5% forceps or vacuum-extractor. For non-operative delivery the predictive variables at admission were age, parity, gestational age and dilation. During hospitalization, fewer vaginal touches,amniotomy or amniorrhexis with clear fluid lead to a shorter induction time and a greater chance of non-operative delivery. False positives and false negatives of the model were always below 50% and correct answers above 65%. Conclusion At admission, age less than 24 years, previous normal births, lower the gestational age and greater the dilation, were predictive of greater probability of nonoperative delivery. During hospitalization, the less vaginal touches and occurrence of amniotomy/amniorrhexis with clear liquid indicate shorter induction time. Future studies with a prospective design and analysis of other factors are necessary to assess the replicability, generalization of these findings.

Resumo Objetivo Determinar os critérios preditivos para o sucesso na indução do trabalho de parto para fetos vivos utilizando misoprostol em gestantes. Em segundo lugar, o objetivo é determinar as taxas de parto vaginal ou cesáreo, duração da indução, intervalo de administração de misoprostol, as principais causas de indução do trabalho de parto e indicação para parto operatório. Métodos Foram revisados os prontuários de 873 gestantes internadas para amadurecimento cervical entre janeiro de 2017 e dezembro de 2018 em um estudo descritivo observacional de análise retrospectiva, considerando as variáveis-resposta: idade, paridade, Índice de Bishop, doses de misoprostol, tempo de indução do trabalho de parto. Modelos de regressão logística foram utilizados para prever o sucesso com misoprostol em partos não operatórios. Resultados Dos 873 pacientes avaliados, 72% evoluíram com parto vaginal, 23% dos casos foram cesáreos, 5% fórceps ou vácuo-extrator. Para o parto não operatório as variáveis preditivas na internação foram idade, paridade, idade gestacional e dilatação. Durante a internação, um menor número de toques vaginais, amniotomia ou amniorrexe com líquido claro, levam a menor tempo de indução e maior chance de parto não operatório. Falsos positivos e falsos negativos do modelo sempre foram inferiores a 50% e respostas corretas acima de 65%. Conclusão Na internação, idade menor que 24 anos, ocorrência de partos normais anteriores, menor idade gestacional e maior dilatação, foram preditivos de maior probabilidade de parto não-operatório. Durante a internação, o menor número de toques vaginais, amniotomia/amniorrexe com líquido claro indicam menor tempo de indução. Estudos futuros com design prospectivo e análise de outros fatores são necessários para avaliar a replicabilidade, generalização desses achados.

Aspiración manual endouterina (AMEU): Revisión de la literatura y estudio de serie de casos / Manual vacuum aspiration (MVA): a literature review and a case series study

Introducción y objetivo El aborto es la pérdida del producto de la concepción antes de la viabilidad fetal y se considera la principal complicación del embarazo. El objetivo de nuestro trabajo es evaluar los resultados iniciales y en mediano plazo del manejo con Aspiración Manual Endouterina (AMEU) del aborto en el primer trimestre. Métodos Análisis estadístico de serie de casos de 53 pacientes sometidas a AMEU en el Hospital Carlos Van Buren, Valparaíso desde noviembre 2017 a junio 2018 por aborto del primer trimestre. El diagnóstico fue clínico y mediante ultrasonografía. Se efectuó un cuestionario de satisfacción posterior al procedimiento. Resultados Se analizaron 53 pacientes, cuya edad promedio es de 29 años, 19 nulíparas, 34 multíparas, con edad gestacional promedio de 8 semanas. Se analizaron 53 biopsias de contenido intrauterino que resultaron en 53 abortos, de éstos 39 retenidos y 14 incompletos. Se registró un 3% de complicaciones (1 caso de perforación uterina que sólo requirió manejo médico y 1 caso de evacuación incompleta). El cuestionario reveló en una mayoría, el alivio de los síntomas y satisfacción en relación al procedimiento. Conclusión La AMEU es una buena alternativa en el manejo del aborto debido a menores costos, baja tasa de complicaciones y alta eficacia. Los centros que disponen de diversas alternativas para el manejo del aborto deben asegurarse de que la mujer participe activamente en la elección en cuanto a su resolución.

ABSTRACT Introduction and objective Miscarriage is the loss of the product of conception before fetal viability and it is considered the main complication of pregnancy. The main objective of our study is to evaluate initial and midterm reports using Manual Vacuum Aspiration (MVA) as management of first trimester miscarriage. Methods Statistic analysis of a case series of 53 patients submitted to MVA at Hospital Carlos Van Buren, Valparaíso since November 2017 until June 2018 with first trimester miscarriage. The diagnosis was clinical and ultrasonographic. A post procedure satisfaction questionnaire was carried out. Results Fifty-three patients were analyzed, with mean age of 29 years, 19 were nulliparous, 34 multiparous, mean gestational age of 8 weeks. Fifty-three intrauterine biopsies were analyzed, of which 53 were miscarriage, 39 retained sacs and 14 incomplete. We had 3% of complications (1 case of uterine perforation requiring only medical treatment and 1 case incomplete vacuum). The questionnaire revealed in a majority, the relief of symptoms and satisfaction with the procedure. Conclusion MVA is a good alternative in the management of miscarriage due to less costs, low rate of complications and high efficacy. The centres with various alternatives for miscarriage management must ensure that the women actively participates in the election of the resolution.

Abortion among women living with or not living with HIV/AIDS users of public health services in São Paulo municipality: prevalence, contexts and reasons / Aborto entre mulheres vivendo e não vivendo com HIV/AIDS usuárias de serviços públicos de saúde no município de São Paulo: prevalência, contextos e motivos

Abstract Objectives: we investigated the lifetime prevalence of abortion and life contexts and reasons reported for first abortion among women living (WLHA) and not living with HIV/AIDS(WNLHA). Methods: representative samples of 975 users of public health care reference network for HIV/AIDS and of 1,003 users of the primary care public services in São Paulo municipality were selected by cluster-stratified sampling and answered an electronic socio-behavioral questionnaire. Results: the prevalence of abortion was 11.9% (CI95%9.8-13.9) among WLHA and 3.0% (CI95%2.4-5.7) for WNLHA.Most abortions (128) among WLHA occurred before diagnosis and 28 after diagnosis or during pregnancy when diagnosis was given. The majority of women did not use any contraception at the time of the first abortion. The use of misoprostol was the most reported method. Having HIV was very important in deciding to abort for half of the WLHA. Absence of marital life and the lack of desire to have children were the most reported reasons by both groups. Conclusions: the similarity in contexts and reasons to abort among WLHA and WNLHA suggests that they share experiences molded by gender and social inequalities that affect their ability to access sexual and reproductive health resources and services.

Resumo Objetivos: investigou-se a prevalência de aborto provocado alguma vez na vida e os contextos de vida e motivos referidos para realização do primeiro aborto entre mulheres vivendo (MVHA) e não vivendo com HIV/AIDS (MNVHA). Métodos: amostras representativas de 975 usuárias da rede especializada em HIV/AIDS e de 1.003 usuárias da rede de atenção básica no município de São Paulo foram selecionadas por amostragem estratificada por conglomerados e responderam um questionário eletrônico sócio-comportamental. Resultados: a prevalência de aborto provocado foi de 11,9% (IC95%9,8-13,9) entre MVHA e de 3,0% (IC95%2,4-5,7) para MNVHA. A maioria dos abortos (128) entre MVHA ocorreu antes do diagnóstico e 28 após o diagnóstico ou na gravidez que este foi dado. A maioria das mulheres não fazia contracepção à época do primeiro aborto. O uso de miso-prostol foi o método mais referido. Ter HIV foi muito importante na decisão de abortar para metade das MVHA. Ausência de vida conjugal e o não desejo de ter filhos foram os motivos mais referidos por ambos os grupos. Conclusões: a semelhança nos contextos e motivos para a realização de aborto entre MVHA e MNVHA sugere que elas compartilham experiências moldadas por desigualdades sociais e de gênero que afetam suas possibilidades de acesso a recursos e serviços de saúde sexual e reprodutiva.

Uso do misoprostol em mulheres com gravidez de alto risco: uma análise retrospectiva / Use of misoprostol in high risk pregnant women: a retrospective analysis

Analisar o intervalo de tempo entre as doses do misoprostol e o número de doses necessárias em gestantes de alto risco para o desencadeamento do trabalho de parto. O trabalho foi retrospectivo baseado em consulta de prontuários médicos de pacientes no período de janeiro a maio de 2017. Foram inclusas, gestantes de alto risco classificadas como nulíparas com apresentação fetal, idade gestacional igual ou superior a 37 semanas e em uso de misoprostol. As variáveis foram analisadas pelo programa Prism versão 5.0, cujos testes quantitativos foram Qui-quadrados de Pearson e teste de Fischer, enquanto as variáveis qualitativas foram teste t student e teste não paramétrico de Mann Whitney. As gestantes com desencadeamento por parto cesariana receberam mais comprimidos que as nulíparas com desencadeamento vaginal (p= 0,04). 25,6% das nulíparas utilizaram ocitocina após a administração do misoprostol. As gestantes de parto cesáreo receberam mais comprimidos para o amadurecimento do colo uterino quando comparado com as nulíparas com desencadeamento por parto vaginal. A maioria das gestantes recebeu doses de misoprostol em intervalos acima das seis horas preconizadas. Outro dado é o alto número de casos absolutos de indicações para o uso de ocitocina, entretanto acreditamos que o motivo de interrupção na utilização do misoprostol seja relacionado à inefetividade do fármaco pela administração em intervalos inadequados. Dessa maneira, o conhecimento sobre o uso do misoprostol no hospital pode contribuir para o uso racional e, consequentemente, maior efetividade do medicamento.

A experiência do aborto na rede: análise de itinerários abortivos compartilhados em uma comunidade online / Abortion experience in the media: analysis of abortive paths shared in an online community

Resumo O objetivo deste artigo é analisar narrativas sobre as experiências de abortar disponíveis em uma comunidade online, buscando discutir os métodos e estratégias aos quais as mulheres recorrem frente à impossibilidade legal de interrupção voluntária de gravidez e os efeitos da criminalização do aborto induzido. Como método, utilizou-se a etnografia virtual, com observação da plataforma Women on Web, coleta e análise de 18 narrativas, disponíveis publicamente e sem restrições, selecionadas entre novembro de 2016 e janeiro de 2017. As narrativas informam métodos mesclados para a realização de aborto, com prevalência de utilização do medicamento Cytotec. Em alguns casos, hospitais e consultórios médicos são incluídos nos itinerários, seja para realização de exames ou para atendimento de intercorrências. A internet se revela uma ferramenta de informação, negociação e mesmo aquisição de medicamento abortivo bastante comum, além de uma plataforma de troca de experiências. Conclui-se que as narrativas sinalizam as inseguranças, riscos e violências às quais estão submetidas as mulheres no contexto da clandestinidade, indicam a importância do debate sobre a descriminalização do aborto no Brasil, e também reforçam a existência de uma cultura compartilhada do aborto, já apontada em estudos anteriores.

Abstract This paper aims to analyze the narratives about abortion experiences available in an online community to discuss the methods and strategies to which women resort, facing the legal impossibility of voluntarily interrupting a pregnancy and the effects of the criminalization of induced abortion. The methodology used was virtual ethnography, observing the platform Women on Web, collection and analysis of 18 narratives publicly available without restrictions, selected between November 2016 and January 2017. The narratives report mixed methods to perform an abortion, with widespread use of Cytotec. Some cases include hospitals and medical clinics in the paths, whether to conduct examinations or attend to intercurrences. The internet appears as a popular tool to gather information, negotiate and even purchase abortive drugs, as well as a platform to share experiences. We concluded that the narratives point to insecurities, risks, and violence to which women are submitted in clandestine setting; they show the relevance of debate on decriminalizing abortion in Brazil, and also reinforce the existence of a shared abortion culture, as stated in other studies.

Medical Termination of Delayed Miscarriage: Four-Year Experience with an Outpatient Protocol / Terminação médica de gravidez inviável do 1° trimestre: quatro anos de experiência com um protocolo de tratamento em ambulatório

Abstract Purpose To evaluate the efficacy of an outpatient protocol with vaginal misoprostol to treat delayed miscarriage. Methods Retrospective analysis of prospectively collected data on women medically treated for missed abortion with an outpatient protocol. The inclusion criteria were: ultrasound-based diagnosis of missed abortion with less than 10 weeks; no heavy bleeding, infection, inflammatory bowel disease ormisoprostol allergy; nomore than 2 previous spontaneous abortions; the preference of the patient regarding the medical management. The protocol consisted of: 1) a single dose of 800 μg of misoprostol administered intravaginally at the emergency department, after which the patients were discharged home; 2) clinical and ultrasonographic evaluation 48 hours later - if the intrauterine gestational sac was still present, the application of 800 μg of vaginal misoprostol was repeated, and the patients were discharged home; 3) clinical and ultrasonography evaluation 7 days after the initiation of the protocol - if the intrauterine gestational sac was still present, surgical management was proposed. The protocol was introduced in January 2012. Every woman received oral analgesia and written general recommendations. We also gave them a paper form to be presented and filled out at each evaluation. Results Complete miscarriage with misoprostol occurred in 340 women (90.2%). Surgery was performed in 37 (9.8%) patients, representing the global failure rate of the protocol. Miscarriage was completed after the first misoprostol administration in 208 (55.2%) women, with a success rate after the second administration of 78.1% (132/169). The average age of the women with complete resolution using misoprostol was superior to the average age of those who required surgery (33.99 years versus 31.74 years; p = 0.031). Based on the ultrasonographic findings in the first evaluation, the women diagnosed with fetal loss achieved greater success rates compared with those diagnosed with empty sac (p = 0.049). Conclusions We conclude this is an effective and safe option in the majority of delayed miscarriage cases during the first trimester, reducing surgical procedures and their consequences.

Resumo Objetivo Avaliar a eficácia de um protocolo de tratamento médico da gravidez inviável do primeiro trimestre (GI1°T) com misoprostol vaginal em regime de ambulatório. Métodos Análise retrospectiva de dados colhidos prospectivamente de grávidas tratadas com misoprostol vaginal em ambulatório. Os critérios de inclusão foram: diagnóstico de GI1°T com < 10 semanas de gestação; ausência de hemorragia abundante, infeção, doença inflamatória intestinal ou alergia ao misoprostol; 2 abortamentos anteriores; e preferência da paciente por tratamento médico. O protocolo consiste em: dia 0-aplicação demisoprostol intravaginal (800μg) no Serviço de Urgência e alta para o domicílio; dia 2-se persistência de saco gestacional intrauterino, aplicação de segunda dose de misoprostol (800μg) e alta; Dia 7-se persistência de saco gestacional intrauterino, proposto esvaziamento uterino instrumentado. O protocolo foi implementado em janeiro de 2012. Todas as grávidas receberam analgesia oral e informação por escrito com recomendações gerais. Receberam ainda um formulário a ser preenchido em cada vinda à urgência. Resultados Das 377 mulheres incluídas, observou-se abortamento completo em 340 (90,2%). As restantes 37 (9,8%) necessitaram de tratamento cirúrgico - taxa de falência global do protocolo. Em 208 (55,2%), o sucesso foi observado ao fim da 1ª dose, com uma taxa de eficácia da 2ª dose de 78,1% (132/169). A idade média das mulheres com sucesso do tratamento médico foi superior à das mulheres sem sucesso do mesmo (33,99 versus 31,74 anos; p = 0,031). O sucesso do tratamento foi maior quando o diagnóstico ecográfico inicial era de um embrião sem vitalidade comparado com os casos de ovo anembrionado (p = 0.049). Conclusões Conclui-se que esta é uma opção de tratamento eficaz e segura na maioria das situações de GI1°T, evitando a necessidade de internamento e de intervenção cirúrgica.

Induction of Labor using Misoprostol in a Tertiary Hospital in the Southeast of Brazil / Indução de parto utilizando misoprostol em um hospital terciário no sudeste do Brasil

Abstract Purpose To assess cases of labor induction with vaginal 25-μg tablets of misoprostol and maternal outcomes in a tertiary hospital in southeastern Brazil. Methods This was a retrospective cohort study of 412 pregnant women with indication for labor induction. Labor induction was performed with vaginal 25-μg tablets ofmisoprostol in pregnant women with Bishop scores < 6. Stepwise regression analysis was used to identify the factors present at the beginning of induction that could be used as predictors of successful labor induction. Results A total of 69% of the pregnant women who underwent labor induction progressed to vaginal delivery, and 31% of the women progressed to cesarean section. One or two misoprostol tablets were used in 244 patients (59.2%). Of the 412 patients, 197 (47.8%) required oxytocin later on in the labor process, after induction with misoprostol. The stepwise regression analysis showed that only Bishop scores of 4 and 5 and previous vaginal delivery were independent factors with statistical significance in the prediction of successful vaginal labor induction (β = 0.23, p < 0.001, for a Bishop score of 4 and 5, and β = 0.22, p < 0.001, for previous vaginal delivery). Conclusion Higher Bishop scores and previous vaginal delivery were the best predictors of successful labor induction with vaginal 25-μg tablets of misoprostol.

Resumo Objetivo Avaliar os casos de indução do trabalho de parto com misoprostol 25 mcg por via vaginal e seus desfechos maternos em um hospital terciário do Sudeste do Brasil. Métodos Realizou-se um estudo retrospectivo de coorte com 412 gestantes com indicações para indução de trabalho de parto. A indução do trabalho de parto foi realizada com misoprostol 25 mcg vaginal em gestantes com índice de Bishop < 6. Realizou-se análise de regressão stepwise para identificar os fatores presentes ao início da indução que poderiam ser usados como prognosticadores do sucesso da indução do trabalho de parto. Resultados A indução de trabalho de parto determinou 69% de partos normais, sendo que 31% evoluíram para cesárea. Em relação ao número de comprimidos de misoprostol, 1 ou 2 comprimidos foram utilizados em 244 pacientes (59,2%). Das 412 pacientes, 197 (47,8%) necessitaramde ocitocina após a indução commisoprostol para dar continuidade ao trabalho de parto. Na análise de regressão stepwise, apenas a presença de índice de Bishop 4 e 5 e parto vaginal prévio foram fatores independentes com significância estatística na predição do sucesso da indução emobter parto vaginal (β = 0,23, p < 0,001, para índice de Bishop 4 e 5, e β = 0,22, p < 0,001, para parto vaginal prévio). Conclusão Maiores índices de Bishop e parto vaginal prévio são os maiores prognosticadores do sucesso de indução de trabalho de parto com misoprostol 25 mcg vaginal.

Effectiveness of per rectal misoprostol versus intramuscular oxytocin for prevention of primary postpartum haemorrhage

Objective: To compare the effectiveness of per rectal misoprostol over oxytocin in primary postpartum haemorrhage [PPH]

Study Design: Randomised controlled trial study

Place and Duration of Study: Gynaecology and Obstetrics Department, Unit IV, Bolan Medical Complex Hospital, Quetta, from September 2013 to February 2014

Methodology: Emergency obstetric patients receiving per rectal misoprostol [800 micro gm] were named as group 'A' and those receiving 10 units oxytocin intramuscularly were labelled as group 'B'. The patients were followed within 24 hours of spontaneous vaginal deliveries. Pads soaked were used to assess the amount of blood loss

Results: A total of 1,678 patients were included in the study. The mean age of patients in group-A was 29.11 years while the mean age of patients in group-B was 29.16 years. One hundred and twenty-three [14.66%] patients in group-A and 120 [14.31%] patients in group-B had PPH. Among the total 1,678 patients, 243 [14.49%] had postpartum haemorrhage among whom 24 [9.88%] had major haemorrhage with a blood loss >/=1000 mL. Among the sub-group [839 patients] administered misoprostol had 123 [14.66%] patients with blood loss greater than 500 mL and the rest 716 patients [85.34%] had blood loss less than 500 mL. The sub-group administered oxytocin have 120 [14.31%] out of 839 patients with postpartum haemorrhage while 719 [85.69%] had blood loss less than 500 mL

Conclusion: Active management of 3rd stage of labour with per rectal misoprostol administration was as effective as intramuscular oxytocin. Both were equally effective to reduce PPH and the subsequent need for surgical interventions

Labour induction; use of sublingual misoprostol versus oxytocin in case of ruptured membranes at term

To compare the efficacy of misoprostol 50ug [sublingual] in comparison with oxytocin infusion than for induction of labour in cases of PROM [premature rupture of membrane at term]. Prospective randomized study. Mujahid Trust Hospital, Faisalabad. Duration: Conducted from Dec 2006 to April 2008. Women were randomized to receive either 50 microgram of sublingual misoprostol every 4 hours with Ringer's lactate solution or oxytocin infusion 10 lU in one litre of Lactated Ringer's solution with a sublingual placebo. Main outcome measures: The number of women delivering vaginally within 24 hours of labour induction. Fifty two women [83%] in misoprostol group and 48 [77%>] in oxytocin group delivered vaginally within 24 hours [relative risk [RR]1.1. However, the induction to vaginal delivery was significantly shorter in the misoprostol group 15+3.7 hours compared with the oxytocin group 18+4.1. The incidence of tachysystole was more than three folds higher in misoprostol than in the oxytocin group [14%] versus 4.3%] RR3.3] but this was not statistically significant. There was no significant difference in the incidence of hypertonus or hyperstimulation syndrome, mode of delivery intervention for fetal distress or neonatal outcomes between the two groups. The group of women received misoprostol for labour induction were found more successful in achieving vaginal delivery in comparatively shorter time and more acceptable to patients. Further studies on safety with large numbers of women need to be conducted before routine use

Preventive Efficacy and Safety of Rebamipide in Nonsteroidal Anti-Inflammatory Drug-Induced Mucosal Toxicity

BACKGROUND/AIMS: The use of proton pump inhibitors or misoprostol is known to prevent the gastrointestinal complications of nonsteroidal anti-inflammatory drugs (NSAIDs). Rebamipide is known to increase the mucosal generation of prostaglandins and to eliminate free oxygen radicals, thus enhancing the protective function of the gastric mucosa. However, it is unknown whether rebamipide plays a role in preventing NSAID-induced gastropathy. The aim of this study was to determine the effectiveness of rebamipide compared to misoprostol in preventing NSAID-induced gastrointestinal complications in patients requiring continuous NSAID treatment. METHODS: We studied 479 patients who required continuous NSAID treatment. The patients were randomly assigned to groups that received 100 mg of rebamipide three times per day or 200 microg of misoprostol three times per day for 12 weeks. The primary endpoint of the analysis was the occurrence rate of gastric ulcers, as determined by endoscopy after 12 weeks of therapy. RESULTS: Of the 479 patients in the study, 242 received rebamipide, and 237 received misoprostol. Ultimately, 44 patients (18.6%) withdrew from the misoprostol group and 25 patients (10.3%) withdrew from the rebamipide group. There was a significant difference in withdrawal rate between the two groups (p=0.0103). The per protocol analysis set was not valid because of the dropout rate of the misoprostol group; thus, the intention to treat (ITT) analysis set is the main set for the efficacy analysis in this study. After 12 weeks, the occurrence rate of gastric ulcers was similar in the rebamipide and misoprostol groups (20.3% vs 21.9%, p=0.6497) according to ITT analysis. In addition, the therapeutic failure rate was similar in the rebamipide and misoprostol groups (13.6% vs 13.1%, p=0.8580). The total severity score of the gastrointestinal symptoms was significantly lower in the rebamipide group than in the misoprostol group (p=0.0002). The amount of antacid used was significantly lower in the rebamipide group than in the misoprostol group (p=0.0258). CONCLUSIONS: Rebamipide can prevent gastric ulcers when used with NSAIDs and can decrease the gastrointestinal symptoms associated with NSAID administration. When the possibility of poor compliance and the potential adverse effects of misoprostol are considered, rebamipide appears to be a clinically effective and safe alternative.

Efectividad del tratamiento médico con misoprostol según dosis administrada en aborto retenido menor de 12 semanas / Effectiveness of medical treatment with misoprostol as abortion retained dose administered in less than 12 weeks

Antecedentes: El manejo terapéutico del aborto retenido consiste en evacuar la cavidad uterina espontáneamente o utilizando misoprostol previo al legrado quirúrgico. Objetivo: Evaluar la necesidad de dilatación mecánica post maduración cervical con misoprostol y la tasa de perforación uterina post legrado, utilizando diferentes dosis de misoprostol en pacientes con diagnóstico de aborto retenido menor a 12 semanas. Métodos: Se registraron datos demográficos y ginecológicos de una cohorte retrospectiva de pacientes con diagnóstico de aborto retenido menor a 12 semanas, entre enero de 2008 y diciembre de 2010. Se establecieron 3 grupos de trabajo según la dosis de misoprostol administrada vía vaginal, siendo de 100 (n=131), 200 (n=231) y 400 micrones (n=230), y se observaron las complicaciones asociadas al procedimiento. Resultados: La necesidad de dilatación mecánica fue significativamente mayor en el grupo que recibió 100 micrones de misoprostol al compararlo con el de 200 micrones y 400 micrones (p<0,01). No hubo diferencias estadísticamente significativas entre las que recibieron 200 versus 400 micrones de misoprostol. No hubo diferencias significativas respecto a perforación uterina. Conclusión: En el aborto retenido menor a 12 semanas, la necesidad de dilatación mecánica post maduración cervical, es menor si se utiliza 200 o 400 micrones de misoprostol, sin diferencias en la tasa de perforación uterina.

Background: The therapeutic management of missed abortion consists on evacuating the uterine cavity, spontaneously or by administration of misoprostol previous to curettage. Objectives: Evaluate the need of mechanical dilatation after cervical maturation with misoprostol and the rate of uterine perforation before curettage, using different doses of misoprostol in patients with diagnosis of missed abortion before 12 weeks. Methods: Demographic and gynecologic data were registered of a retrospective cohort of patients with the diagnosis of missed abortion before 12 weeks, between January 2008 and December 2010. Three groups were established according to the dose of misoprostol: 100 (n=131), 200 (n=231) and 400 microns (n=230). Complications associated to the procedure were observed. Results: The need of mechanical dilatation was significant higher for the group with 100 microns of misoprostol in comparison with 200 and 400 microns (p<0.001). There was no statistical significance among who received 200 versus 400 microns of misoprostol. No statistical significance was found for uterine perforation. Conclusion: In the missed abortion before 12 week, the need of mechanical dilatation is lower with 200 or 400 microns of misoprostol, without difference in uterine perforation rate.

Misoprostol use under routine conditions for termination of pregnancies with intrauterine fetal death / Uso de misoprostol na rotina para terminar gestações com feto morto

OBJECTIVE: To analyze the misoprostol use in pregnancies with intrauterine fetal death (IUFD), considering mode of delivery and induction-delivery interval. METHODS: Descriptive study including 171 pregnant women with IUFD, in the second or third trimester, submitted to labor induction with vaginal misoprostol and/or induction/augmentation with intravenous oxytocin, from 2005 to 2008, at a teaching-hospital of the Brazilian Unified Health System (Sistema Único de Saúde -SUS). RESULTS: Misoprostol alone (treatment A), misoprostol plus oxytocin (treatment B), and oxytocin alone (treatment C) were administered in 9.3%, 19.9%, and 70.8% of the cases, respectively. One-third of pregnancies were less than 28 weeks, and 2.9% required a caesarean section. The percentage of vaginal delivery in treatments A and B combined (98.0%) was similar to treatment C (96.7%). The mean induction-delivery interval was 15.4 hours. Comparing multiple groups, the mean induction-delivery interval was significantly shorter in treatment A (20.1 hours) than in treatment B (33.3 hours), and was longer than in treatment C (9.7 hours). The majority (71%) of cases required a single administration of misoprostol, and the total dosage was lower in treatment A (mean: 98.4 µg) compared with treatment B (mean: 157.0 µg). CONCLUSION: Misoprostol effectively contributed to delivery of IUFD by vaginal route assisted under routine conditions of a public health service in Brazil, demonstrating its importance in cases resistant to usual induction methods, and its availability in Brazilian public health services is recommended.

OBJETIVO: Descrever o uso de misoprostol em gestações com óbito fetal intraútero, considerando o tipo de parto e o intervalo indução-parto. MÉTODOS: Estudo descritivo de 171 gestantes com óbito fetal intraútero, no segundo ou terceiro trimestres, submetidas à indução do parto com misoprostol vaginal ou aceleração do parto com ocitocina parenteral, de 2005 a 2008 em um hospital-escola do Sistema Único de Saúde (SUS) do Brasil. RESULTADOS: Misoprostol isolado (tratamento A), misoprostol complementado pela ocitocina (tratamento B) e ocitocina isolada (tratamento C) foram administrados em 9,3%, 19,9% e 70,8% dos casos, respectivamente. Um terço das gestações estavam com menos de 28 semanas e 2,9% delas requereram operação cesariana. O percentual de parto vaginal nos tratamentos A e B combinados (98,0%) foi similar ao tratamento C (96,7%). A média do intervalo indução-parto foi menor no tratamento A (20,15 horas; DP = 15,8 horas) comparado ao tratamento B (33,31 horas; DP = 29,6 horas) e a proporção de partos pela via vaginal ocorridos dentro de 48 horas foi de 100% (tratamento A), 96,7% (tratamento B) e 96,7% (tratamento C). A maioria dos casos (71%) tratados com misoprostol requereu uma única administração da droga e a média da dosagemtotal foi menor no tratamento A (média 98,4µg) comparado ao tratamento B (média: 157,0µg). CONCLUSÃO: Misoprostol efetivamente contribuiu para a resolução de gestações com óbito fetal intraútero, mostrando a importância de sua aplicação em casos resistentes aos métodos usuais de indução e de sua disponibilização nos serviços públicos de saúde no Brasil.

Métodos terapêuticos de maturação cervical / Therapeutic methods for cervical ripening

Métodos de maturação cervical são utilizados há décadas, apresentando mecanismos, efetividade e riscos diversos. Para reconhecer os métodos existentes e delimitar quais possuem os menores riscos, melhor efetividade e disponibilidade na prática médica, foi realizada uma revisão crítica, que buscou artigos nas bases Medline/Pubmed, biblioteca Cochrane e LILACS/SciELO, referentes à maturação cervical mecânica ou farmacológica em gestantes com termos e palavras-chave relacionadas à maturidade cervical, misoprostol e parto induzido. Constatou-se que os métodos mais utilizados na prática são a prostaglandina sintética (misoprostol) e a sonda de Foley. Estes se mostraram superiores aos demais métodos encontrados, uma vez que são efetivos, têm baixo custo, são fáceis de armazenar e utilizar, especialmente o misoprostol. Ambos apresentaram uma efetividade similar, mas os métodos mecânicos estão relacionados a um maior risco de infecção.

Cervical ripening methods have been used for decades, showing different mechanisms, risks and effectiveness. To recognize the existing methods and delineate which have the lower risks, best availability and effectiveness in clinical practice, a critical review was conducted, which sought articles in Medline / Pubmed, Cochrane Library, and LILACS/SciELO regarding mechanical or pharmacological cervical ripening in pregnant women, with terms and keywords related to cervical ripening, misoprostol and induced labor. It was found that the most used methods in practice are synthetic prostaglandin (misoprostol) and the Foley catheter. They seem to be superior to other methods because they are effective, inexpensive and easy to store and use, especially misoprostol. Both showed a similar efficacy, but mechanical methods are related to a higher risk of infection.

Induction of labor with titrated oral misoprostol solution versus oxytocin in term pregnancy: randomized controlled trial / Indução do trabalho de parto por meio de solução oral titulada de misoprostol versus oxitocina em gestação a termo: estudo controlado randomizado

PURPOSE: To evaluate the effectiveness and the safety of orally administered misoprostol in comparison to intravenously infused oxytocin for labor induction in term pregnant women. METHODS: Between 2008 and 2010, a total of 285 term pregnant women whom were candidate for vaginal delivery were assessed for eligibility to enter the study. Twenty five patients were excluded for different reasons; and 260 included women were randomly assigned to one of the two groups according to the method of treatment, misoprostol or oxytocin. The misoprostol group received 25 µg every 2 hours for up to 24 hours for induction. The oxytocin group received an infusion of 10 IU which was gradually increased. The time from induction to delivery and induction to the beginning of the active phase and successful inductions within 12, 18, and 24 hours were recorded. The trial is registered at irct.ir, number IRCT2012061910068N1. RESULTS: Failure of induction, leading to caesarean section was around 38.3% in the oxytocin group and significantly higher than that of the misoprostol group (20.3%) (p<0.001). Despite the more prevalent failure in the oxytocin group, the mean time intervals from induction to active phase and labor of this group were both significantly less than the misoprostol group (10.1±6.1 and 13.2±7.7 versus 12.9±5.4 and 15.6±5.1 hours respectively, both p-values were <0.05). Maternal and fetal complications were comparable between groups except gastrointestinal symptoms which were encountered more frequently in the misoprostol (10.9 versus 3.9%, p=0.03). CONCLUSIONS: Misoprostol is a safe and effective drug with low complications for the induction of labor. Failure is seen less with misoprostol and caesarean sections are less frequently indicated as compared to oxytocin.

OBJETIVO: Avaliar a eficácia e segurança do misoprostol administrado por via oral em comparação à infusão de oxitocina para a indução do trabalho de parto em gestantes a termo. MÉTODOS: Entre 2008 e 2010, um total de 285 gestantes a termo candidatas para parto vaginal foram avaliadas quanto à eligibilidade para inclusão no estudo. Vinte e cinco pacientes foram excluídas por várias razões, e as 260 mulheres incluídas foram divididas aleatoriamente em dois grupos de acordo com o método de tratamento, misoprostol ou oxitocina. O grupo tratado com o misoprostol recebeu 25 µg cada 2 horas durante um máximo de 24 horas para indução. O grupo tratado com oxitocina recebeu infusão de 10 UI, que foi aumentada gradativamente. O tempo a partir da indução até o início da fase ativa e as induções bem-sucedidas dentro de 12, 18 e 24 horas foram registrados. O ensaio foi registrado em irct.ir, número IRCT2012061910068N1. RESULTADOS: A falha de indução levando à necessidade de cesariana foi de aproximadamente 38.3% no grupo tratado com oxitocina, sendo significativamente maior em relação ao grupo tratado com misoprostol (20,3%) (p<0,001). Apesar da falha mais prevalente no grupo tratado com oxitocina, os intervalos médios entre indução e fase ativa e trabalho de parto nesse grupo foram ambos significativamente menores em relação ao grupo tratado com misoprostol (10,1±6,1 e 13,2±7,7 versus 12,9±5,4 and 15,6±5,1 horas, respectivamente, sendo ambos os p-valores <0,05). Complicações maternas e fetais foram comparáveis entre grupos, com exceção dos sintomas gastrointestinais, que foram encontrados mais frequentemente no grupo tratado com misoprostol (10,9 versus 3,9%, p=0,03). CONCLUSÕES: O misoprostol é droga segura e eficaz para a indução do parto, com poucas complicações. Falhas são menos observadas e cesáreas são indicadas menos frequentemente com o misoprostol em relação à oxitocina.

Efectividad del tratamiento médico con misoprostol en pacientes con aborto incompleto que acudieron al Hospital Nacional Dos de Mayo: enero-diciembre 2012 / Effectiveness of medical treatment with misoprostol in patients with incomplete abortion attended at the National Hospital Dos de Mayo: january-december 2012

El presente trabajo de investigación surge a raíz de la resistencia, temor y la falta de compromiso del personal médico del HNDM (Hospital Nacional Dos de Mayo) para incorporar el Misoprostol como primera alternativa en el tratamiento del aborto incompleto precoz, esto quizás por el miedo a las complicaciones y por ende a los problemas médico legales a pesar de que existen varias revisiones sistemáticas quienes demuestran fehacientemente la efectividad del Misoprostol en el tratamiento del aborto incompleto precoz. Este trabajo de investigación es mediante un estudio Descriptivo, Transversal y retrospectivo el cual nos permitirá demostrar una vez más la efectividad y beneficios del Misoprostol en pacientes que acudieron al HNDM y que fueron diagnosticados de aborto incompleto y recibieron tratamiento médico con Misoprostol en relación al Tx quirúrgico, esto permitirá motivar al personal de salud del HNDM a incorporar al Misoprostol como tratamiento de primera línea en el aborto incompleto precoz. El número total de abortos en general en el Hospital Nacional Dos de Mayo en el periodo de Enero a Diciembre del 2012 fue 496 de los cuales 322 (65 por ciento) fueron aborto incompleto que cumplían los criterios para el TX médico, y solo 111 (34 por ciento) recibieron tratamiento médico con misoprostol 600 mcg vía oral en dosis única y 153 (48 por ciento) termino en AMEU y 58 (18 por ciento) en EBA más LU. El servicio de Gineco Obstetricia del HNDM cuenta con 28 Gíneco Obstetras de los cuales solo 12 (43 por ciento) realiza tratamiento médico con misoprostol y 16 (57 por ciento) tratamiento quirúrgico (AMEU-LU) a pacientes con aborto incompleto que cumplen los criterios para TX médico, siendo las principales causas: resistencia al cambio 56 por ciento, temor a las complicaciones 31 por ciento y falta de capacitación 13 por ciento. De un total de 111 HCL con abortos incompletos que reciben tratamiento médico con misoprostol el 78 por ciento son menores de 30 años y el...

The present research stems from the resistance, fear and lack of commitment HNDM medical staff to incorporate Misoprostol as first aIternate in the earIy treatment of incompIete abortion, that perhaps the fear of compIications and hence medico-legal probIems even though there are several systematic reviews who clearly demonstrate the effectiveness of MisoprostoI in the treatment of earIy incomplete abortion. This research is a descriptive, transversal and retrospective which will allow us to further demonstrate the effectiveness of Misoprostol in patients attending the HNDM and who were diagnosed with incomplete abortion with Misoprostol received medical treatment, this will allow us to motivate the HNDM health staff to incorporate the Misoprostol as first line treatment of incomplete abortion in earIy. The total number of abortions in general in the National Hospital Dos de Mayo in the period from January to December 2012 was 496 of which 322 (65 per cent) were incomplete abortion that met the criteria for the TX doctor, and only 111 (34 per cent) received medical treatment with Misoprostol 600 mcg orally in a single dose and 153 (48 per cent) ended in MV A and 58 (18 per cent) in aduIt education more LV The Department of Obstetrics and Gynecology of the HNDM account with 28 Ob/gyns of which only 12 (43 per cent) performs medical treatment with Misoprostol and 16 (57 per cent) TX in surgical patients with incomplete abortion that meet the criteria for TX doctor, being the main causes: resistance to change 56 per cent, fear of complications 31 per cent and lack of training 13 per cent.

Introducción: el misoprostol es un producto extremadamente útil como fármaco abortivo, tiene un alto margen de seguridad cuando es pautado en dosis adecuadas y con una correcta supervisión médica. Objetivo: evaluar la eficacia de misoprostol, en la dilatación del cérvix en el aborto instrumentado en gestantes de hasta 9 semanas, Métodos: se realizó un estudio experimental, entre enero y diciembre de 2011, en el Hospital General Docente Iván Portuondo del municipio San Antonio de los Baños, provincia Artemisa, que compara 2 formas de administración de 400 mcg de misoprostol. El universo estuvo constituido por un total de 620 pacientes, de ellos 224 conformaron la muestra. Resultados: 113 pacientes recibieron tratamiento por vía vaginal y 111 por vía sublingual, 202 casos tuvieron una dilatación eficaz y 22 casos se comportó como no eficaz. En más de las 2/3 partes de los casos, el tiempo necesario para la interrupción fue normal, seguido por las que fue prolongado para un 16,1 por ciento y en último, las que tuvieron un tiempo quirúrgico corto, con un 11,6 por ciento. Los efectos secundarios que más se presentaron fueron la fiebre y escalofríos en el caso de la vía sublingual en más de un 50 por ciento. Conclusiones: la administración previa de 400 mcg de misoprostol en el aborto instrumentado, resulto ser más efectiva para la dilatación cervical cuando se colocó vía vaginal en contraste con la vía sublingual

Introduction: misoprostol is an extremely useful product to be used as abortive drug, it has a high margin of safety when prescribed at adequate doses and with a proper medical supervision.Objective: to evaluate the efficacy of misoprostol in the dilation of the cervix in instrumented abortion in pregnant women up to 9 weeks,Methods: it was conducted an experimental study, between January and December 2011, at Ivan Portuondo General Teaching Hospital of San Antonio de los Baños municipality, Artemisa province, which compares two forms of administration of 400 mcg of misoprostol. The universe consisted of a total of 620 patients, of which 224 formed the sample.Results: 113 patients were vaginally treated and 111 sublingually, 202 cases had an effective dilatation and 22 cases behaved ineffectively. In more than 2/3 parts of the cases, the time required for termination was normal, followed by those prolonged to 16,1 per cent and finally, those who had a short surgical time with 11,6 per cent. Side effects that occurred more frequently were fever and chills in the case of the sublingual administration over 50 per cent.Conclusions: prior administration of 400 mcg of misoprostol in instrumented abortion, proved to be more effective for cervical dilation when placed vaginally in contrast to sublingually
