The pregnant women in group B did not show statistically significant differences in the frequency of obstetric variables compared to the pregnant women in group C (p = ns). Conclusion : There was a significant association between pregestational obesity and the risk of birth alterations.

Uterine tamponade in postpartum hemorrhage with handmade balloons: Comparison of manufacturing, infusion, and total times.

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

Desfechos de partos em gestantes que positivaram COVID-19 em município paranaense / Outcomes of deliveries in pregnant women who tested positive for COVID-19 in a municipality in Paraná

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

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

Nonpharmacological labor pain management methods and risk of cesarean birth: A retrospective cohort study.

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

Macrosomía fetal y factores de riesgo asociados en la provincia Camagüey

Introducción: La macrosomía fetal, de manera tradicional, ha sido definida por un peso arbitrario al nacer; la misma, ya sea definida por un límite de peso o grande para la edad gestacional, se asocia con numerosas complicaciones perinatales y maternas. Objetivo: Describir los factores de riesgo asociados a la macrosomía fetal en los partos del Hospital Universitario Ginecobstétrico Provincial Ana Betancourt de Mora durante el año 2019. Métodos: Se realizó un estudio observacional descriptivo de corte transversal. El universo quedó constituido por la totalidad de gestantes que tuvieron recién nacidos con peso al nacimiento mayor o igual a 4 000 gramos, el cual ascendió a 526 gestantes. Se utilizó estadística descriptiva. Se calculó media y desviación estándar a las variables cuantitativas. Resultados: Las gestantes estudiadas tenían una media de edad de 27,86 años y un IMC a la captación como promedio de 26,77 con un valor medio de ganancia de peso de 13,68 Kg. Entre los 26 y 35 años hubo 290 gestantes con recién nacidos macrosómicos, respecto a la paridad las que paren sin experiencia de este reunió a 222 grávidas. En las embarazadas catalogadas de sobrepeso con ganancia de 10 a 15 kg se reúnen 104 de los recién nacidos macrosómicos. Respecto al tipo de parto la cesárea representó el 61,4 %. Se observó en 40 gestantes la presencia de diabetes gestacional o pregestacional y preeclampsia respectivamente. Conclusiones: La ganancia excesiva de peso en gestantes con evaluación nutricional de sobrepeso u obesas tuvo la mayor incidencia en la génesis de la macrosomía en los recién nacidos.

Introduction: Fetal macrosomia has traditionally been defined by an arbitrary birth weight. Fetal macrosomia, whether defined by borderline weight or large for gestational age, is associated with numerous perinatal and maternal complications. Objective: To describe the risk factors associated with fetal macrosomia in deliveries at Ana Betancourt de Mora Provincial Gyneco-Obstetric University Hospital during 2019. Methods: A cross-sectional descriptive observational study was carried out. The study universe was made up of all pregnant women who had newborns with a birth weight greater than or equal to 4 000 grams, which amounted to 526 pregnant women. Descriptive statistics were used. Average and standard deviation were calculated for the quantitative variables. Results: The studied pregnant women had an average age of 27.86 years and an average BMI at uptake of 26.77 with an average value of weight gain of 13.68 Kg. Between 26 and 35 years there were 290 pregnant women with newborn macrosomic births, with respect to parity those who give birth without experience of this brought together 222 gravid women. In pregnant women classified as overweight with a gain of 10 to 15 kg, 104 of the macrosomic newborns are gathered. Regarding the type of delivery, cesarean section represented 61.4%. The presence of gestational or pregestational diabetes and preeclampsia, respectively, was observed in 40 pregnant women. Conclusions: The excessive weight gain in pregnant women with nutritional evaluation of overweight or obese were those that had the highest incidence in the genesis of macrosomia in newborns.

Amenazas a la seguridad de la paciente por la conducción del parto con oxitocina. Experiencia en un hospital público de Lima, Perú / Threats to the safety of the patient due to the delivery management with oxytocin. Experience in a public hospital in Lima, Peru

Resumen OBJETIVO Identificar las amenazas a la seguridad de la paciente en la práctica de la conducción del trabajo de parto con oxitocina y las repercusiones maternas y perinatales en un hospital público de tercer nivel de Lima, Perú. MATERIALES Y MÉTODOS Estudio cuantitativo, descriptivo, retrospectivo y transversal efectuado en pacientes embarazadas atendidas en un hospital público, de tercer nivel, de Lima, Perú, a quienes se indicó conducción del parto con oxitocina. Los datos se tabularon en Excel y SPSS v21. El análisis univariado incluyó frecuencia y porcentaje para las variables cualitativas; se emplearon medidas de tendencia central, dispersión y desviación estándar para variables cuantitativas. RESULTADOS Se revisaron 112 historias clínicas de pacientes sin alteraciones en el trabajo de parto a quienes se indicó conducción con oxitocina (29.5%; n = 33). La principal vía de término fue el parto vaginal (73.2%; n = 82) y del grupo con cesárea el motivo más común fue la desproporción céfalo pélvica (56.7%; n = 17). Se observaron complicaciones obstétricas en 25% (n = 28), de este grupo la principal fue la hemorragia posparto (46.4%; n = 13). El peso de los recién nacidos fue 3401 ± 394 gramos, 93.7 y 96.4% obtuvieron un Apgar entre 10 a 7 al primero y quinto minutos, respectivamente. CONCLUSIONES Las amenazas identificadas a la seguridad de la paciente fueron: conducción del parto con oxitocina en quienes no tenían alteraciones en el trabajo de parto y en quienes tuvieron desproporción céfalo-pélvica, a pesar de que es una contraindicación para el procedimiento.

Abstract OBJECTIVE Identify the threats to the safety of the patient in the practice of conducting labor with oxytocin and maternal and perinatal outcomes in a public tertiary hospital in Lima, during 2016. MATERIALS AND METHODS Quantitative, descriptive, retrospective and cross-sectional. A total 112 pregnants' medical histories were review who underwent augmentation of labour with oxytocin. Inclusion criteria's: term gestation, hospitalization with a 4 cm dilatation, fetuses in cephalic presentation. Exclusion criteria's: patients with previous or intercurrent pathologies to pregnancy. RESULT The augmentation with oxytocin made in pregnant women without alterations in labor (29.5%; n = 33). The main type childbirth was vaginal delivery (73.2%; n = 82) and of the group that underwent cesarean section, the most usual reason was cephalopelvic disproportion (56.7%; n = 17). Obstetric complications were observed (25%; n = 28), of this group the main was postpartum hemorrhage (46.4%; n = 13). The weight of the newborns oscillated between 3401 ± 394 g, 93.7% and 96.4% obtained an Apgar 10 to 7 at the 1st and 5th minute respectively. CONCLUSIONS The threats to the safety of the patient identified were the practice of augmentation of labor with oxytocin in pregnant women without alterations in labor and in pregnant women with cephalopelvic disproportion, although it is a contraindication to the procedure.

Excesso de peso materno e início da amamentação ­ revisão analítica de estudos observacionais / Maternal overweight and breastfeeding initiation ­ an analytic review of observational studies

Este artigo tem o objetivo de realizar uma revisão analítica de estudos observacionais que avaliaram a relação entre o excesso de peso materno e o tempo de início do aleitamento materno, com enfoque nos fatores que podem atuar como mediadores da associação. Extensa revisão foi realizada nas bases de dados PubMed/MEDLINE, Google Acadêmico e Bireme/Lilacs utilizando um conjunto de termos relacionados ao início do aleitamento materno e ao excesso de peso materno. As referências dos artigos incluídos foram manualmente revisadas para identificar artigos não revelados anteriormente. Os critérios de seleção foram: idioma português, inglês ou espanhol; estudos originais, e estudo realizado em humanos. Vinte e nove artigos, provenientes de 24 diferentes estudos foram incluídos nas análises. A avaliação desses estudos indica que o excesso de peso materno atua como fator de risco importante para o não início do aleitamento materno e que esse risco se acentua com o aumento no grau de excesso de peso materno. Fatores psicológicos, raça, formas corporais e complicações gestacionais/obstétricas são variáveis maternas que parecem interagir com o excesso de peso, influenciando o início da amamentação. (AU)

This paper aims to propose an analytic review of observational studies that addressed the influence of maternal overweight on breastfeeding initiation, with emphasis on the factors that can act as mediators on this association. A search on PubMed/MEDLINE, Google Scholar and Bireme/Lilacs databases was conducted applying a number of descriptors related to breastfeeding and maternal body mass index. The reference lists of included articles were handsearched to identify further relevant studies. Selection criteria were: original articles, with human subjects, published in Portuguese, English or Spanish. A total of 29 papers from 24 different studies were included in the analysis. Maternal overweight was an important risk factor for failure to initiate breastfeeding. The risk was accentuated by the increase in maternal body mass index. Psychological factors, ethnicity, body shape and obstetric complications seem to interact with maternal overweight to interfere in breastfeeding initiation. (AU)

Factors associated with the need for ventilation at birth of neonates weighing >/=; 2, 500 g

OBJECTIVES: Approximately 20-40% of annual global neonatal deaths occur among infants with birthweights ≥2,500 g, and most of these deaths are associated with intrapartum asphyxia in low- and middle-income countries. This study aims to evaluate the peripartum variables associated with the need for resuscitation at birth of neonates weighing ≥2,500 g. METHOD: This case-control retrospective study was performed on data from all public reference maternity units in the state of Ceará, Northeast Brazil, between March 2009 and March 2010. The subjects were singleton neonates without malformations weighing ≥2,500 g, who required positive-pressure ventilation in the delivery room. The controls had a 1-minute Apgar score of ≥8 and did not undergo resuscitation. Variables associated with positive-pressure ventilation in the delivery room were evaluated via conditional multivariate logistic regression. RESULTS: Of the 2,233 live births with birth weights ≥2,500 g, 1-minute Apgar scores ≤7, and no malformations, 402 patients met the inclusion criteria, and they were paired with 402 controls. Risk variables for positive-pressure ventilation at birth were a gestational age <37 weeks (OR: 3.54; 95% CI: 1.14-10.92) and meconium-stained amniotic fluid (8.53; 4.17-17.47). Cervical examination at maternal admission (0.57; 0.38-0.84) and a written follow-up of the labor (0.68; 0.46-0.98) were identified as protective variables. CONCLUSIONS: Significant flaws in obstetric care are associated with the need for positive-pressure ventilation at birth for neonates weighing ≥2,500 g.

Risk factors for severe obstetric perineal lacerations.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to assess the occurrence of severe perineal lacerations in vaginal delivery and its relationship with predisposing clinical and obstetric factors. METHODS: A retrospective cohort analysis using an electronic clinical database at a University Referral Center for high-risk pregnancies was performed. A total of 941 vaginal deliveries were analyzed, over 10 consecutive months in 2013 and 2014. The relationship between obstetric and clinical characteristics and lacerations, especially severe forms, was analyzed. The frequency and severity of birth canal lacerations were compiled and classified as mild (unintentional laceration grades I and II, and mediolateral episiotomy) and severe (grades III and IV). The crude and adjusted odds ratios and 95% confidence intervals were estimated in univariate and multivariate logistic regression models. RESULTS: The overall incidence of perineal lacerations in vaginal delivery was 78.2% (n = 731). Lacerations were considered mild in 708 women (75.7%) and severe in 23 women (2.5%). Maternal age, parity, use of forceps, mediolateral episiotomy, and birth weight influenced the occurrence of some degree of tear. The chance of severe lacerations increased 1.77-fold per week with the gestational age (1.03-3.03, P = 0.025), while primiparity increased the chance of laceration 5.32-fold. Episiotomy did not show a protective effect against severe laceration occurrence (P = 0.999). CONCLUSIONS: Severe perineal lacerations were associated with operative delivery, primiparity, gestational age, and epidural anesthesia. Episiotomy was not protective.

[Caesarean section: History, epidemiology, and ethics to diminish its incidence]. / Operación cesárea. Una visión histórica, epidemiológica y ética para disminuir su incidencia.

Cesarean section has become the most performed surgery and it has been enhanced with the use of antibiotics and improvement in surgical techniques. The aim of this systematic review is to describe and clarify some historical and ethical characteristics of this surgery, pointing out some aspects about its epidemiological behavior, becoming a topic that should be treated globally, giving priority to the prevention and identification of factors that may increase the incidence rates. Today, this "epidemic" reported rates higher than fifty percent, so it is considered a worldwide public health problem. Consequently, in Mexico strategies aimed at its reduction have been implemented. However, sociocultural, economic, medicolegal and biomedical factors are aspects that may difficult this goal. As we decrease the percentage of cesarean section in nulliparous patients, we diminish the number of iterative cesarean and its associated complications. This aim must be achieved through the adherence to the guidelines which promote interest in monitoring and delivery care in health institutions of our country.

La operación cesárea es la cirugía mayor más frecuentemente practicada, y ha sido perfeccionada con el uso de antibióticos y mejores técnicas quirúrgicas. El objetivo de esta revisión sistemática es describir y precisar diversas características históricas y éticas con relación a esta intervención quirúrgica, señalando algunos aspectos inherentes a su comportamiento epidemiológico, siendo este último una problemática de actualidad y de suma importancia que debe tratarse de forma integral, dando prioridad a la prevención e identificación de los factores que hacen posible el aumento en las tasas de incidencia. Hoy en día, esta "epidemia" reporta tasas que superan el cincuenta por ciento, por lo que se ha considerado un problema de salud pública a nivel mundial. Consecuentemente, en México se han implementado estrategias tendentes a su disminución, no obstante, los factores socioculturales, económicos, médico-legales y biomédicos son aspectos que dificultan dicho objetivo. En la proporción en que se disminuya el porcentaje de cesárea en pacientes primigestas, disminuirá secundariamente el número de cesáreas iterativas y sus complicaciones asociadas, meta que debe alcanzarse mediante el apego a las guías que promueven el interés por la vigilancia y atención del parto en las instituciones de salud de nuestro país.

Maternal near miss among women using the public health system in the Amazon and Northeast regions of Brazil / Morbilidad materna extremadamente grave entre las usuarias del sistema de salud pública en las regiones amazónica y noreste del Brasil

OBJECTIVE: To assess the prevalence of pregnancy complications identified as maternal near miss (MNM) and associated factors among women using the public health care system in the Amazon and Northeast regions of Brazil. METHODS: A secondary analysis of a population-based survey conducted in 2010 was performed focusing on women self-reporting maternal complications. The main outcome was MNM, pragmatically defined as intensive care unit admission, eclampsia, hysterectomy, or blood transfusion. In addition, the risk of MNM was estimated for certain sociodemographics and characteristics of care received. Poisson regression was performed, generating adjusted prevalence ratios (PRadj) with 95% confidence intervals (95%CI). RESULTS: A total of 13 044 women (77%) who had given birth during the prior year using the public health system were interviewed. At least one complication was reported by 37.5%, with hemorrhage (28.4%) and infection (8.3%) being the most frequent. The overall MNM ratio was 31.5 per 1 000 live births, higher for the Amazon region than for the Northeast. Factors with a higher risk for developing MNM were: indigenous ethnicity (PRadj 2.77; 95% CI: 1.50-5.14), more than one hour to reach the hospital (PRadj 1.55; 95%CI: 1.06-2.25), being refused by a full hospital and having to find another one (PRadj 1.49; 95%CI: 1.03-2.16), cesarean section (PRadj 2.56; 95%CI: 1.90-3.44), and public prenatal care (PRadj 1.95; 95%CI: 1.06-3.61). CONCLUSIONS: Users of public health system in the Amazon and Northeast regions of Brazil have high MNM rates. Some characteristics of the women and of the care they received represent inequalities associated with higher risk for MNM. Specific actions are required to improve maternal health programs in these expansive areas of the country.

OBJETIVO: Evaluar la prevalencia de las complicaciones del embarazo establecidas como morbilidad materna extremadamente grave (MMEG), y los factores asociados, entre las usuarias del sistema de atención de salud pública en las zonas amazónica y noreste del Brasil. MÉTODOS:Se realizó un análisis secundario de una encuesta poblacional llevada a cabo en el 2010 y centrado en las mujeres que autonotificaban complicaciones obstétricas. El principal resultado fue la MMEG, definida a efectos prácticos como ingreso en una unidad de cuidados intensivos, eclampsia, histerectomía o transfusión de sangre. Se calculó además el riesgo de MMEG para determinadas características sociodemográficas y de la atención recibida. Se llevó a cabo una regresión de Poisson y se generaron las razones de prevalencia ajustadas (RPa) con intervalos de confianza de 95% (IC 95%). RESULTADOS:Se entrevistó a un total de 13 044 mujeres (77%) que habían dado a luz durante el año previo en el sistema de salud pública. Un 37,5% notificó como mínimo una complicación; la hemorragia (28,4%) y la infección (8,3%) fueron las más frecuentes. El índice general de MMEG fue de 31,5 por 1 000 nacidos vivos, más elevado en la región amazónica que en la noreste. Los factores que comportaron un riesgo mayor de MMEG fueron la etnicidad autóctona (RPa 2,77; IC 95% = 1,50-5,14), precisar más de una hora para llegar al hospital (RPa 1,55; IC 95% = 1,06-2,25), no ser admitida en un hospital por estar completo y tener que encontrar otro (RPa 1,49; IC 95% = 1,03-2,16), la cesárea (RPa 2,56; IC 95% = 1,90-3,44), y la asistencia prenatal pública (RPa 1,95; IC 95% = 1,06-3,61). CONCLUSIONES: Las usuarias del sistema de salud pública en las regiones amazónica y noreste del Brasil muestran tasas elevadas de morbilidad materna extremadamente grave. Algunas características de las mujeres y de la atención recibida comportan desigualdades asociadas con un riesgo mayor de morbilidad materna extremadamente grave. Se requieren acciones específicas que mejoren los programas de salud materna en estas amplias zonas del país.

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.

Uso de balões intrauterinos em pacientes com hemorragia pós-parto / Use of intrauterine balloons in patients with postpartum haemorrhage

A hemorragia pós-parto é uma complicação presente em mais de 18% dos nascimentos e responsável por cerca de 25 a 30% das mortes maternas no mundo. No Brasil, apesar da ampliação do acesso aos serviços de saúde e da melhoria em praticamente todos os indicadores de saúde materna, esta etiologia continua se apresentando entre os três principais grupos de causas de morte no ciclo grávido-puerperal. Nas últimas décadas, várias técnicas conservadoras visando o controle hemorrágico no período pós-parto têm sido relatadas, com destaque para as técnicas de desvascularização uterina, suturas compressivas, embolização arterial, balões intrauterinos e a interrupção do ato operatório com laparostomia, empacotamento pélvico e posterior reabordagem cirúrgica. O presente artigo apresenta uma revisão do uso de balões intrauterinos no controle hemorrágico com destaque para os tipos, aplicabilidades e cronologia de invenção e publicações. Foram avaliados os balões de Sengstaken-Blakemore, os artesanais, as sondas de Foley, balão de Rusch, de Bakri e o BT-cath. Detalhou-se também o teste do tamponamento e a técnica do "sanduíche uterino".(AU)

Postpartum hemorrhage is present in over 18% of births and accounts for 25-30% of maternal deaths worldwide. In Brazil, despite the expansion of access to health care and the improvement of virtually all maternal health indicators, such etiology is still present among the three main causes of death during pregnancy and childbirth. In the last decades, several conservative techniques direct at controlling hemorrhage in the postpartum period have been reported, principally techniques of uterine devascularization, compression sutures, arterial embolization, intrauterine balloons and surgery interruption with laparostomy, pelvic packing and subsequent surgical intervention. This article presents a review of the use of intrauterine balloons in controlling hemorrhage especially types, applicability and chronology of invention and publications. Sengstaken-Blakemore balloons, the artisanal, Foley probes, Rusch balloon, Bakri and BT-cath were reviewed. The tamponade test and the "uterine sandwich" technique were also detailed.(AU)

Influencia de la hipertensión originada por el embarazo en el parto y el recién nacido / Influence of hypertension caused by pregnancy in delivery and by the newborn

Introducción: la preeclampsia representa un gran riesgo para la madre y el producto de la concepción. Objetivo: evaluar la repercusión que tiene la hipertensión originada por el embarazo en la gestación, el parto y el recién nacido. Material y método: se realizó una investigación prospectiva, longitudinal y analítica en el Policlínico Universitario "Hermanos Cruz", en el período comprendido entre mayo de 2011 y mayo de 2012; el universo de estudio estuvo conformado por todas las gestantes pertenecientes a dicho policlínico, mientras la muestra se formó con 130 gestantes que se dividieron en dos grupos, el grupo estudio las pacientes a las que se les diagnosticó un preeclampsia (n = 31) y el grupo control gestante sin la enfermedad (n = 93). Se analizaron diferentes variables del parto y el neonato. Los resultados se calcularon a través del test de ji cuadrado con nivel de significación de p < 0,05. Resultados: la prematuridad se presentó en el 22.58 %, la inducción del parto fue utilizada en 19 gestantes, la cesárea se realizó en el 70.97 %, los neonatos con bajo peso se presentaron en el 54.84 % del grupo estudio y el 38.71 % de los recién nacidos tuvieron puntaje de Apgar bajo a los cinco minutos. Todas las variables fueron altamente significativas. Conclusiones: la preeclampsia influye negativamente en el parto y el recién nacido. Además de considerarse como factor de riesgo para que se produzcan eventos nocivos en la madre y el neonato.

Introduction: preeclampsia is a major risk to the mother and her offspring. Objective: to evaluate the impact of hypertension caused by pregnancy in gestation, delivery and by the newborn. Material and methods: it was performed a prospective, longitudinal and analytical research at Hermanos Cruz University Outpatient Clinic in the period between May 2011 and May 2012, the universe consisted of all pregnant women belonging to that clinic, while the sample was made up of 130 pregnant women, and were divided into two groups: the study group of patients who were diagnosed with preeclampsia (n=31) and the control group of pregnant women without the disease (n=93). Different variables of childbirth and the newborn were analyzed. The results were calculated by the chi-square test with a significance level of p < 0.05. Results: prematurity was presented in 22.58%, delivery induction was used in 19 pregnant women, cesarean section was performed in 70.97 %, low-weight neonates presented in 54.84 % of the study group and 38.71 % of newborns had low Apgar score at five minutes of birth. All variables were highly significant. Conclusions: preeclampsia is affecting the delivery and the newborn. It is also considered as a risk factor for adverse events that occur in the mother and the newborn.
