Complicaciones obstétricas y edad materna avanzada

La edad materna avanzada guarda relación directamente proporcional con el riesgo de complicaciones obstétricas y no obstétricas durante la gestación, tanto para la gestante como para el feto. Esto es particularmente importante debido a que a las tasas de fecundidad de las mujeres de mayor edad han aumentado. En Estados Unidos, el 10% del primer nacimiento y el 20% de todos los nacimientos ocurren en mujeres con 35 años o más. Históricamente la edad materna avanzada se ha definido como una edad mayor o igual a 35 años, punto de corte que sustentado en la disminución de la fecundidad y el mayor riesgo de anomalías genéticas en la descendencia de las mujeres mayores a esta edad. Sin embargo, los efectos relacionados al aumento de edad son continuos y el riesgo es mayor mientras mayor sea la edad al momento de la concepción más que como efecto de pasar el umbral de los 35 años. Diferentes investigaciones han mostrado que las gestantes añosas tienen mayor riesgo de complicaciones tempranas de la gestación como aborto espontáneo, embarazo ectópico, anomalías cromosómicas y malformaciones congénitas, así como, preeclampsia, diabetes gestacional, patología placentaria, parto pretérmino, peso bajo al nacer, mortalidad perinatal, embarazo múltiple, parto distócico, parto por cesárea y mortalidad materna. En este artículo se revisa publicaciones recientes sobre el tema y se incluye estadística de un importante hospital de Lima, Perú, y de la Encuesta Nacional de Demografía y Salud Familiar - ENDES 2022.

Advanced maternal age is directly proportional to the risk of obstetric and nonobstetric complications during gestation, both for the pregnant woman and the fetus. This is particularly important because the fertility rates of older women have increased. In the US, 10% of first births and 20% of all births occur to women 35 years of age or older. Historically, advanced maternal age has been defined as an age greater than or equal to 35 years, a cutoff point that is supported by declining fertility and the increased risk of genetic abnormalities in the offspring of women older than this age. However, the effects related to increasing age are continuous and the risk is greater the older the age at conception rather than as an effect of passing the 35 years threshold. Research has shown that older pregnant women are at increased risk of early pregnancy complications such as miscarriage, ectopic pregnancy, chromosomal abnormalities and congenital malformations, as well as, preeclampsia, gestational diabetes, placental pathology, preterm delivery, low birth weight, perinatal mortality, multiple pregnancy, dystocic delivery, cesarean delivery and maternal mortality. This article reviews recent publications on the subject and includes statistics from a major hospital in Lima, Peru, and from the National Demographic and Family Health Survey - ENDES, 2022.

Chinese Medicine Plaster as A New Treatment for Surgical Site Infection in Patients with Cesarean Delivery: A Randomized, Double-Blind, Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the efficacy of Chinese plaster containing rhubarb and mirabilite on surgical site infection (SSI) in patients with cesarean delivery (CD) by performing a randomized controlled trial.@*METHODS@#This randomized controlled trial included 560 patients with CD due to fetal head descent enrolled at a tertiary teaching center between December 31, 2018 and October 31, 2021. Eligible patients were randomly assigned to a Chinese medicine (CM) group (280 cases) or a placebo group (280 cases) by a random number table, and were treated with CM plaster (made by rhubarb and mirabilite) or a placebo plaster, respectively. Both courses of treatment lasted from the day 1 of CD, followed day 2 until discharge. The primary outcome was the total number of patients with superficial, deep and organ/space SSI. The secondary outcome was duration of postoperative hospital stay, antibiotic intake, and unplanned readmission or reoperation due to SSI. All reported efficacy and safety outcomes were confirmed by a central adjudication committee that was unaware of the study-group assignments.@*RESULTS@#During the recovery process after CD, the rates of localized swelling, redness and heat were significantly lower in the CM group than in the placebo group [7.55% (20/265) vs. 17.21% (47/274), P<0.01]. The durution of postoperative antibiotic intake was shorter in the CM group than in the placebo group (P<0.01). The duration of postoperative hospital stay was significantly shorter in the CM group than in the placebo group (5.49 ± 2.68 days vs. 8.96 ± 2.35 days, P<0.01). The rate of postoperative C-reactive protein elevation (≽100 mg/L) was lower in the CM group than in the placebo group [27.6% (73/265) vs. 43.8% (120/274), P<0.01]. However, there was no difference in purulent drainage rate from incision and superficial opening of incision between the two groups. No intestinal reactions and skin allergies were found in the CM group.@*CONCLUSIONS@#CM plaster containing rhubarb and mirabilite had an effect on SSI. It is safe for mothers and imposes lower economic and mental burdens on patients undergoing CD. (Registration No. ChiCTR2100054626).

Does prophylactic use of postcesarean section laxatives favor bowel movements?

Introduction: Chronic constipation (CC) is a highly prevalent disease in Western society. Chronic constipation can have a different etiology in patients who underwent a cesarean section and result from postoperative stress and metabolic response to trauma, analgesic agents, immobilization, and dietary restrictions. Chronic constipation may also occur due to puerperium-related psychological changes and to the stretching and weakening of the perineal and abdominal muscles after childbirth. Objectives: The present study analyzes intestinal transit restoration after a cesarean section and the influence of osmotic laxative agents. Methods: The present prospective, nonrandomized sample study used the ROME III questionnaire and the Bristol stool scale in adult women who underwent a cesarean section. We divided the subjects into 2 groups, each with 30 patients, to compare the effect of the prophylactic administration of an osmotic laxative. Results: We evaluated 60 randomly-chosen pregnant women from the Obstetrics ward of Hospital Santa Marcelina, São Paulo, SP, Brazil, from October 2019 to March 2020. Their mean age was 26.8 years old, and the mean gestation time was 37.95 weeks. Ten patients (16.7%) presented with constipation before the cesarean section, and 38 (63.3%) had a bowel movement after the procedure. However, in 84.2% of these patients, the usual stool consistency worsened. After the cesarean section, 46.7% of the women who did not receive laxative agents had a bowel movement, compared with 80% of those who did (p = 0.0074). Conclusion: Some factors, including those related to the procedure, may hamper intestinal transit restoration after a cesarean section. Osmotic laxative agents can facilitate transit restoration with no negative effects in this group of patients. (AU)

Introdução: O centro do conceito de humanização é a dignidade e o respeito à vida humana, enfatizando a dimensão ética na relação entre pacientes e profissionais de saúde. O tema humanização na área da saúde é de extrema relevância, uma vez que consagra como premissa básica o atendimento de qualidade ao paciente. Os profissionais de enfermagem envolvidos especialmente no processo do parto cesariana devem oferecer assistência qualificada, acolhedora e humanizada. Objetivo: Avaliar a assistência de enfermagem no parto cesariana, no centro obstétrico sob o olhar da humanização. Métodos: Tratou-se de um estudo exploratório de abordagem qualitativa. Participaram do estudo 10 profissionais de enfermagem, sendo 6 enfermeiras obstetras e 4 técnicas em enfermagem, todas do sexo feminino, idade entre 25 e 38 anos, tempo de atuação na área entre 1 e 13 anos. A coleta de dados foi configurada por meio de entrevista semiestruturada, e análise de dados por categorização dos dados. Resultados e Conclusão: A equipe de enfermagem está humanizando o parto cesariana, de acordo com as diretrizes do Ministério da Saúde, mesmo com a limitação do parto cirúrgico, a cena se configura no binômio e família, observou-se o respeito à escolha do acompanhante, sala aquecida e na penumbra, contato pele a pele, corte tardio do cordão umbilical, e aleitamento na primeira hora do parto, além do envolvimento da equipe de enfermagem, demonstrando respeito à individualidade, ética e postura proativa no que se refere ao parto em cena.

Introduction: At the core of the concept of humanization are dignity and respect to human life, emphasizing the ethical dimension of the relationship between patients and healthcare professionals. The matter of humanization in healthcare is extremely relevant as it establishes quality patient care as a basic premise. Nursing professionals especially involved in the cesarian delivery process should offer qualified, welcoming, and humanized care. Objective: To evaluate nursing care during cesarean deliveries at an obstetric unit from the viewpoint of humanization. Methods: This is an exploratory study with a qualitative approach. Participants were 10 nursing professionals, of which 6 were obstetric nurses and 4 were practical nurses; all of them were female, aged between 25 and 38 years, and had been working in nursing for 1 to 13 years. Data collection was performed via a semistructured interview, and data analysis was done by categorizing data. Results and conclusion: The nursing team is humanizing cesarian deliveries, according to guidelines by the Ministry of Health; despite the limitations of surgical delivery, the scene revolves around the binome and the family, and we observed respect for the choice of support partner, heated room, dimmed lights, skin-to-skin contact, delayed umbilical cord clamping, and breastfeeding in the first postpartum hour. In addition, the involvement of the nursing team demonstrated respect to individuality, ethics, and a proactive approach when considering the delivery scene.

Objetivo: Este artigo de revisão sistemática tem como objetivo analisar as principais características relacionadas à infeção puerperal em mulheres submetidas ao parto cesáreo. Fonte dos dados: Foi realizada busca nas bases de dados on-line Biblioteca Virtual de Saúde (BVS) e PubMed. Seleção dos estudos: Selecionaram-se artigos publicados nos últimos 11 anos (2010-2021), totalizando 12 artigos analisados. Coleta de dados: Realizou-se a busca dos artigos a partir dos descritores infecção puerperal, mortalidade materna, cesárea, fatores de risco em inglês e português. Em seguida à adequação aos critérios de inclusão (artigos em inglês, português e espanhol, com publicação nos últimos 11 anos, realizados em humanos) e exclusão (artigos duplicados, revisão de literatura, estudos de caso e dissertações), a análise dos títulos e dos resumos dos artigos encontrados permitiu a exclusão daqueles que se afastavam do tema em estudo. Síntese dos dados: Dentre os fatores sociodemográficos, destacam-se mulheres nos extremos de idade, negras, residentes na zona rural, com baixo nível econômico e escolar, primíparas e tabagistas. Em relação aos fatores clínicos, obesidade, HIV, diabetes mellitus, doenças cardiovasculares, hipertensão arterial, pré-eclâmpsia e eclâmpsia, anemia e infecções geniturinárias apresentaram-se como fatores de risco para infecção puerperal. Fatores obstétricos também foram avaliados, identificando-se como variáveis importantes o parto cesáreo, rotura prematura de membranas, tempo de membrana rota, trabalho de parto maior que 12 horas, parto prematuro e trabalho de parto induzido, hemorragia pós-parto, transfusão prévia e mecônio em líquido amniótico. Por fim, as características assistenciais trazem o baixo número de consultas de pré-natal e número de toques vaginais antes e após a ruptura de membranas como variáveis de risco. Conclusão: Muitos dos fatores identificados são passíveis de controle, e a sua reversão contribui para a redução dos índices de infecção puerperal e, consequentemente, de mortalidade materna.(AU)

Objective: This systematic review article aims to analyze the main characteristics related to puerperal infection in women undergoing cesarean delivery. Source of data: A search was performed in the online databases Virtual Health Library (VHL) and Pub- Med. Selection of studies: Articles published in the last 11 years were selected, totaling 12 analyzed articles. Data collection: Articles were searched based on the keywords puerperal infection, maternal mortality, cesarean section, risk factors in English and Portuguese. Following the adaptation to the inclusion criteria (articles in English, Portuguese and Spanish, publication in the last 11 years, carried out in humans) and exclusion (duplicates, literature review, case studies and dissertations), the analysis of the titles and abstracts of the found articles allowed the exclusion of those who departed from the topic under study. Summary of the findings: Among the sociodemographic factors, women of extreme age, blacks, residents in the rural area, with low economic and educational status, primiparous women and smokers, stand out. Regarding clinical factors, obesity, HIV, Diabetes Mellitus, Cardiovascular Diseases, Hypertension, Pre-eclampsia and Eclampsia, Anemia and genitourinary infections were risk factors for puerperal infection. Obstetric factors were also evaluated, identifying as important variables cesarean delivery, premature rupture of membranes, ruptured membrane time, labor longer than 12 hours, premature labor and induced labor, postpartum hemorrhage, previous transfusion and meconium in amniotic fluid. Finally, the care characteristics bring the low number of prenatal consultations, the number of vaginal touches before and after rupture of membranes as risk variables. Conclusion: Many of the identified factors are possible to control and their reversion contributes to the reduction of puerperal infection rates and consequently maternal mortality.(AU)

Association between primiparas’ willingness of a second child and cesarean section / 上海预防医学

ObjectiveTo explore the impact of primiparas’ intention to have a second child on their delivery mode. MethodsDuring March 1st， 2019 and November 30th， 2020， the enrolled pregnant women were investigated by questionnaires at two points， first trimester pregnancy registration and post-natal visit at maternal and child healthcare community centers of Xuhui District. Logistic regression analysis was used to examine the association of willingness of a second birth and their mode of delivery. Results2 000 questionnaires were distributed and 1 664 valid questionnaires were analyzed. The overall cesarean delivery rate in nulliparous women was 40.08% （667/1 664）， with 8.95% （149/1 664） of non-medical indication cesarean delivery. Multiple Logistic regression analysis of overall delivery rate showed that age， willingness to have more children in the future， plan of vaginal delivery at first questionnaire， and complications during pregnancy were associated with overall cesarean delivery rate， and women without the willingness to have more children in the future were more likely to undergo cesarean delivery （OR=1.350， 95%CI： 1.052-1.732）. Age， whether to have a second child in the future， plan of vaginal delivery at first questionnaire， and complications during pregnancy were all factors associated with increased risks of non-medical indicated cesarean delivery， while women with no plan of a second child in the future had nearly 2 times of risk of non-medical indicated cesarean delivery （OR=1.909， 95%CI： 1.117-3.262）. ConclusionThe mode of delivery is affected by many factors， among which willingness to have more children in the future is an important factor associated with increased risks of overall cesarean delivery and non-medical indicated cesarean delivery.

Fascitis necrotizante por Enterococcus gallinarum en una puérpera. Presentación de un caso / Necrotizing fasciitis due to Enterococcus gallinarum in a pospartum patient. Case report

RESUMEN Fundamento: La fascitis necrotizante es una infección que se desarrolla de manera rápida, afecta la piel, tejido celular subcutáneo, fascia superficial y en ocasiones la profunda, en heridas quirúrgicas al producir necrosis hística y severa toxicidad sistémica. Es una afectación sistémica acompañante, que a su vez a ella se asocian factores predisponentes endógenos como: diabetes mellitus, obesidad, alcoholismo, infección por VIH, y exógenos: cirugía ginecobstétrica, inyecciones, traumatismos; por lo que estos pacientes resultan ser enfermos críticos en las unidades de cuidados intensivos, con un curso clínico no uniforme, al llevar a una evolución fulminante cuando corresponde con la variante hiperaguda o fulminante. Objetivo: Describir la presencia de fascitis necrotizante hiperaguda causada por Enterococcus gallinarum, en una puérpera. Reporte de caso: Puérpera que se le practicó parto distócico por cesárea electiva a las 38.3 semanas, a las 24 h presentó manifestaciones generales que se acompañaron de lesiones en la piel; se le realizó cirugía ginecobstétrica, su evolución fue tórpida y falleció por fallo multiorgánico a los 3 días debido a las consecuencias de fascitis necrotizante hiperaguda o fulminante, causada esta por un Enterococcus gallinarum. Conclusiones: La fascitis necrotizante es una enfermedad poco frecuente y mortal si no se trata a tiempo; su diagnóstico resulta difícil en su fase inicial, debido a que casi siempre es clínico. El tratamiento quirúrgico debe ser urgente, combinarse este con antibióticoterapia sistémica, debido al germen causal y la toxicidad que producen.

ABSTRACT Background: Necrotizing fasciitis is an infection that develops rapidly, affecting the skin, subcutaneous cellular tissue, superficial fascia and sometimes deep fascia, in surgical wounds by producing hystenotic necrosis and severe systemic toxicity. It is a supplementary systemic affectation, which in turn is associated with endogenous predisposing factors such as: diabetes mellitus, obesity, alcoholism, HIV infection, and exogenous: gynecobstetric surgery, injections, traumatisms; so these patients are critical patients in intensive care units, with a non-uniform clinical progression, leading to a fulminant evolution when parallel to the hyperacute or fulminant variant. Objective: To describe the presence of hyperacute necrotizing fasciitis caused by Enterococcus gallinarum in a puerperal. Case report: A puerperal who suffered from dystocia delivery by elective cesarean section at 38.3 weeks, at 24 h presented general manifestations accompanied by skin lesions; she underwent gynecobstetric surgery, her evolution was torpid and she died of multiorgan failure after 3 days due to the consequences of hyperacute or fulminant necrotizing fasciitis, caused by Enterococcus gallinarum. Conclusions: Necrotizing fasciitis is a rare and fatal disease if not treated in time; its diagnosis is difficult in its early phase because it is often clinical. Surgical treatment should be urgent and combined with systemic antibiotic therapy due to the causative germ and the toxicity they produce.

Síndrome de QT largo en la embarazada con el uso de la oxitocina

RESUMEN Introducción: Los síndromes de QT largo adquiridos pueden ser provocados por el uso de fármacos, dentro de los cuales se encuentra la oxitocina. Objetivo: Identificar los cambios electrocardiográficos con el uso de la oxitocina intravenosa en la embarazada. Método: Se realizó un estudio descriptivo-prospectivo con 57 embarazadas a las que se les realizó cesárea electiva y se le administró oxitocina, inmediatamente después de la extracción fetal, en el Hospital Universitario Gineco-Obstétrico Mariana Grajales de Villa Clara, Cuba, durante el período de septiembre de 2019 a enero de 2020. Resultados: El 63,2% de las pacientes tuvo un QT corregido 470 ms; en estas últimas, un 5,3% lo tuvo entre 481-500 ms, e igual porcentaje > 500 ms. Ninguna paciente presentó síntomas sugestivos o demostración electrocardiográfica de taquicardia ventricular u otras arritmias complejas. Conclusiones: La oxitocina, administrada en el período de alumbramiento, produjo prolongación del intervalo QT por encima de los valores normales en algunas pacientes, sin que se produjeran síntomas cardiovasculares, dispersión del QT o arritmias complejas.

ABSTRACT Introducción: Acquired long QT syndromes may be due to the use of drugs, within which oxytocin is included. Objetivo: To identify electrocardiographic disturbances related to intravenous oxytocin administration in pregnant women. Método: A descriptive-prospective study was conducted with 57 pregnant women who underwent elective caesarean section and were given oxytocin, immediately after fetal extraction, at the Hospital Universitario Gineco-Obstétrico Mariana Grajales in Villa Clara, Cuba, between September 2019 and January 2020. Resultados: The 63.2% of the patients had a corrected QT interval 470 ms; in the latter, 5.3% had it between 481-500 ms, and equal percentage > 500 ms. No patient presented suggestive symptoms or electrocardiographic demonstration of ventricular tachycardia or other complex arrhythmias Conclusiones: Oxytocin, given during the placental removal period, resulted in the prolongation of the QT interval above normal values in some patients, without the appearance of cardiovascular symptoms, QT interval dispersion or complex arrhythmias.

Comparison of post-operative outcomes between enhanced recovery after surgery versus standard operative protocol among cesarean delivery mothers at a tertiary hospital

@#This Randomized Controlled Trial sought to determine whether mothers who underwent Cesarean delivery had better postoperative outcomes when subjected to the Enhanced Recovery After Surgery (ERAS) protocol compared to mothers who also underwent Cesarean section as a mode of delivery but were under the Standard operative protocol. The research concentrated on evaluating the postoperative outcomes of the patients in the study through the following factors: length of hospitalization, efficiency and cost-effectiveness of hospital expenses, early resumption of diet and early ambulation, breastfeeding initiation and continuation. A total of 72 subjects were included in the study. Two were not included due to conversion to general anesthesia. Thirty two (44.4%) were randomized to the ERAS protocol while 40 (55.6%) patients were randomized to Standard postoperative procedure. Demographic characteristics were recorded and comparable between the two groups. Mothers randomized to the ERAS protocol had significantly shorter length of stay compared to mothers in the standard operative procedure with a mean of 53.01 hours (2.21 days) and 78.86 hours (3.29 days) respectively. Mothers randomized to the ERAS protocol spent significantly lower hospitalization cost compared to mothers in the standard operative procedure. There was no significant difference noted in the proportion of mothers with fever between the two groups (p=0.25). Mothers randomized to the ERAS protocol had significantly lower post-operative pain compared to mothers in the standard operative procedure. The time from end of OR until general liquids was also significantly shorter among mothers randomized to the ERAS protocol compared to mothers in the standard operative procedure. Similarly, the time from end of OR to flatus and bowel movement was also significantly shorter among mothers randomized to the ERAS protocol compared to mothers in the standard operative procedure. The time from end of OR to removal of foley catheter and time to void after foley catheter removal was also significantly shorter among mothers randomized to the ERAS protocol compared to mothers in the standard operative procedure. Finally, there was a significant difference noted in the length of time from end of OR to breastfeeding as proven by all p value of 0.02. Mothers randomized to the ERAS protocol had significantly shorter length of time from end of OR to breastfeeding compared to mothers in the standard operative procedure with a mean of 30.67 hours and 43.09 hours respectively. Ultimately, the study concentrated on Emergency or Elective Cesarean deliveries of Low risk patients as well as patients with controlled gestational or overt diabetes mellitus, thyroid disorders in euthyroid state, and hypertensive disorders not complicated with eclampsia. This study did not seek to generalize the benefit of ERAS protocol on all Cesarean deliveries. ERAS protocol showed better postoperative outcomes compared to the Standard operative protocol in terms of shorter length of hospital confinement, lower cost of hospitalization, no occurrence of post-operative infections and complications, shorter length of time from operation to diet progression tolerance, passage of flatus, bowel movement, shorter length of time from end of OR to removal of foley catheter and time to void and finally shorter time from operation to initiation of breastfeeding and continuation.

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

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

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

Incidence of cesarean delivery after induction of labor with intravenous oxytocin drip among women undergoing induction of labor at Dessie referral hospital, Northeast Ethiopia, 2017

Background:The number of delivering women undergoing an induction of labor is greater than 20% and continues to rise. Simultaneously, the cesarean delivery rate continues to increase as well. This increase has resulted from evidence-based recommendations on how to handle certain conditions. Labor induction has been associated with increased likelihood of cesarean birth for some groups of women.Methods:Institutional based retrospective cross sectional study was conducted on 319 women medical chard who undergone induction of labor with oxytocin infusion at Dessie referral hospital. Systematic sampling techniques was used to select the samples. The data was cleaned, edited, coded, and entered in to EPI INFO version 3.5 and exported and analyzed by SPSS with windows version 20.0.Results:A total of 319 delivery records were reviewed. Out of this 256 (80.3%) was successful induction of labor. Incidence of cesarean section after induction of labor with oxytocin infusion among women at Dessie referral hospital was 136 (42.6%). The most frequent cause of induction of labor was due to hypertensive disorder 133 (41.7%) followed by pre labor rupture of membrane 111 (34.8%). Cesarean section was done due to failed induction of labor 63 (19.7%) followed by fetal distress 40 (12.5%).Conclusions:In present study incidence of cesarean delivery after induction of labor was 42.6%. Most frequent cause of induction of labor was due to hypertensive disorder followed by pre-labor rupture of membrane. Cesarean section was done due to failed induction of labor followed by fetal distress.

ABSTRACT Introduction : The pandemic of coronavirus disease 2019 (COVID-19) has spread to more than 100 countries. Specific information about its behavior in pregnancy is still limited. Objective: To describe the maternal and perinatal characteristics of pregnant patients infected with COVID-19 and their newborns in a tertiary referral hospital. Methods : Descriptive study. Subjects were all pregnant patients admitted to the OB/ GYN Emergency Department of the Edgardo Rebagliati Martins National Hospital from March 24 to May 7, 2020, who were diagnosed with SARS-CoV-2 infection by rapid test or by RT-PCR test. Medical and hospital records were reviewed to retrieve sociodemographic data, patient's history, clinical manifestations, maternal serology, obstetric complications, delivery mode and perinatal aspects. Results : 41 patients diagnosed with SARS-CoV-2 were identified. 9.2% of all admissions had a positive rapid test. The most common symptoms were cough in 84.6%, fever in 76.9% and sore throat in 61.5%. 68.2% of the patients were asymptomatic, 19.5% had mild illness and 7.3 %, moderate. 2 cases progressed to severe pneumonia requiring non-invasive ventilation. No maternal deaths were recorded. 21.7% were vaginal deliveries, while 78.3% were C-sections. One baby born in a vaginal delivery had a positive PCR result on day 8. Conclusions : A large percentage of asymptomatic pregnant patients had a positive PCR test. Implementing universal screening among patients in labor as part of the pregnant patient flow protocol is necessary for all institutions.

The neonatal outcomes of Dexamethasone administration before scheduled cesarean delivery at term: a randomized clinical trial

Background: Caesarean delivery (CD) rates in developing countries are rising beyond the recommended rates of World health organization. Objective of this study was to evaluate whether Dexamethasone injections reduce neonatal incubation admissions when given before scheduled caesarean delivery (CD) at term or not.Methods: A double blinded, two armed, randomized clinical trial was conducted at Tanta University hospitals in the period from October 2017 to March 2019. Four hundred pregnant women admitted for scheduled CD with gestational age ≥37 weeks were included. Patients were randomized into study group and control group. The study group was given 3 dexamethasone doses, 8 mg each while control group was given saline injections simultaneously as a placebo drug. The primary outcome was the neonatal incubatory admissions.Results: Demographic data in both groups were comparable. Transient tachypnea of newborn (TTN) was 15.47% in study group versus 20.33% in control group with p=0.227. The respiratory distress (RDS) in study group was 6.63% versus 9.89% in control group with p=0.260. The incubation admissions were nasal oxygen 12.71% versus 15.38%, continuous positive airway pressure ventilation (CPAP) 5.52% versus 8.24% and mechanical ventilation was 3.87% versus 6.59% in the study and control groups respectively.Conclusions: Although Dexamethasone administration before scheduled CD at term reduced both respiratory morbidity and incubation admissions, the differences between study and control groups were not significant.

A study of rate, indications and maternal morbidity associated with cesarean delivery in a tertiary care hospital

Background: Cesarean section is one of the most commonly performed surgical procedures in obstetrics worldwide. Over  the last three decades, a tremendous increase in cesarean section rates has been observed globally, which is a cause for concern as procedure is associated with higher morbidity and mortality compared to vaginal delivery. This study was done to analyze the rate and indications for cesarean section and associated maternal morbidity and mortality.Methods: This retrospective study was conducted over a period of 6 months from 1st October 2017 to 31st March 2018 in the department of Obstetrics and Gynecology, Integral Institute of Medical Sciences and Research, Lucknow, India. Data of patients who were admitted for delivery in department of Obstetrics and Gynecology in OPD or emergency were recorded. Statistical analysis of various parameters namely, the cesarean section rates, its indications, the patient’s morbidity and mortality was done.Results: The total numbers of women delivered over the study period were 577, out of which 210 patients underwent cesarean sections. The overall cesarean section rate in our study was 36.39%. Previous cesarean section was the leading indication of cesarean section (31.9%) followed by arrest of labor (18.1%), CPD (14.2%), and fetal distress (12.9%). Breech presentation (5.2%), failed induction of labor (4.8%), pregnancy induced hypertension (PIH) (3.8%), oligohydramnios (3.3%), obstructed labor (2.4%), APH (1.4%), multiple pregnancy and BOH accounted for 0.95% of cesarean sections. 9% patients had few complications mainly minor wound infection (2.4%) and postpartum hemorrhage (2%). There was no mortality during this period.Conclusions: Previous cesarean section has been found to be the main indication for cesarean section. So primary cesarean section should be reduced to decrease the overall cesarean rates. A comprehensive, evidence based approach needs to be introduced to monitor indication of all cesarean section.

Evaluation of amniotic fluid volume and its relation to perinatal outcome

Background: In pregnancy amniotic fluid surrounds the foetus and plays an important role in the development of fetus. From the very beginning of the formation of the extracoelomic cavity amniotic fluid can be detected. To evaluate the predictive value of amniotic fluid index (AFI) (<5) for adverse perinatal outcome in terms of cesarean section for fetal distress, birth weight, meconium staining, Apgar scores, and NICU admission at birth.Methods: This was a prospective study of 100 antenatal women visited RMC, Ajmer, Rajasthan, India during the year 2018 with gestational age >34 weeks. The women’s history, clinical examination recorded, and AFI were measured and the perinatal outcome was compared between two groups, i.e., AFI <5 and >5.Results: The cesarean section rate for fetal distress, low birth weight babies, <2.5 kg and meconium staining was higher in patients with oligohydramnios (p=0.012, 0.001, 0.00015 respectively). There was no significant difference in Apgar score at 5 min <7 (p=0.087) and NICU at birth between the two groups.Conclusions: Oligohydramnios has a significant correlation with cesarean section for fetal distress, low birth weight babies and NICU admission.

Effect of tranexamic acid in prevention of postpartum hemorrhage in elective caesarean delivery: a randomized controlled study

Background: Postpartum hemorrhage is the ugly ghost that most obstetricians believe because many cases unpredicted and may be associated with rapid patient deterioration that may lead mortality or developing serious long-term morbidities. The objective of this study is to assess the efficacy of slowly intravenous administration of tranexamic acid in prevention and decline the severity of postpartum hemorrhage immediately prior to elective caesarean section.Methods: A double blinded, randomized, case control trial carried out at Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Egypt from May 2017 to April 2018. This study was conducted on 500 full term pregnant women underwent elective caesarean section. The patients were divided randomly into: Group A (study group) included 250 patients received tranexamic acid 1gm slowly iv over 2 minutes at least 10 minutes before operation started and Group B (control group) included 250 patients that received placebo (normal saline NaCl 0.9%).Results: Incidence of PPH in group A and group B were (4.4% and 6.8) respectively, 1.2% in group A and 2.8% in group B had severe degree of PPH. Amount of blood loss immediately after placental delivery up to first 6 hours postoperative was statistically significant increase in placebo group than tranexamic acid group with p value <0.001.Conclusions: Tranexamic acid administration few minutes prior to elective cesarean section was effective in reducing the incidence and severity of PPH and decreased the use of additional uterotonic drugs and additional surgical interventions.

Risk prevention of neuraxial labor analgesia / 中国实用妇科与产科杂志

Labor pain threatens the health of mother and infant seriously and it accounts for the biggest part of non-medical indications of cesarean section in our country.Neuraxial labor analgesia is the most effective and commonly used therapy for pain relief during labor and delivery without increasing the rate of cesareansection.However,it can cause some side effects and complications like supine position syndrome,inadequate anesthesia and fever.To strengthen the process management of labor analgesia,clear assignment of responsibility,carring out education and training and developing complication treatment plan are important measures to prevent risks.

Influence of early treatment of pregnancy combined with subclinical hypothyroidism on pregnancy outcome / 中国基层医药

Objective To analyze the influence of early treatment of pregnancy combined with subclinical hypothyroidism (SCH) during pregnancy on pregnancy outcome.Methods From January 2013 to June 2015,128 pregnant women who were diagnosed as SCH in the Maternal and Child Health Hospital of Beilun District were randomly divided into the observation group and control group according to the digital table,with 64 cases in each group.The observation group was given levothyroxine early treatment,while the control group adopted conventional hospitalization,unexposed.Pregnancy outcomes of the two groups were analyzed.Results After treatment,the incidence rates of complications in the observation group:preeclampsia (4.69％),poor fetal growth (1.56％),premature rupture of membranes (7.81％),less amniotic fluid volume (4.69％),placental abruption (0％),postpartum hemorrhage (3.12％);the incidence rates of complications in the control group:preeclampsia (17.19％),poor fetal growth (10.94％),premature rupture of membranes (21.88％),less amniotic fluid volume (15.63％),placental abruption (6.25％),postpartum hemorrhage (12.50％),and there were statistically significant differences between two groups (x2 =5.133,4.800,5.006,4.195,4.129,3.905,P =0.023,0.028,0.025,0.041,0.042.0.048).After treatment,the incidence rates of adverse pregnancy outcomes:preterm birth (3.12％),cesarean section (60.94％),abortion (0.00％),fetal distress (4.69％),perinatal death (0.00％);the incidence rates of adverse pregnancy outcomes in the control group:preterm birth (12.50％),cesarean section (79.69％),abortion (7.81％),fetal distress (15.63％),perinatal death (6.25％),and the differences between the two groups were statistically significant (x2 =3.905,5.389,5.203,4.195,4.129,P =0.048,0.020,0.023,0.041,0.042).Conclusion Pregnancy complicated with SCH has different degree influence on patients with obstetric complications and outcome of pregnancy,early effective drug treatment can significantly reduce the incidence of obstetric complications and adverse pregnancy outcomes.

Anesthesia for cesarean delivery in a patient with Klippel-Trenaunay syndrome / Anestesia para parto cesáreo em paciente portadora de síndrome de Klippel-Trenaunay

Abstract Introduction: Klippel-Trenaunay syndrome is a rare congenital vascular disease characterized by cutaneous hemangiomas, varicosities, and limb asymmetry, which may evolve with coagulation disorders and hemorrhage as those more frequent complications in pregnant patients. Pregnancy is not advised in women with this syndrome due to increased obstetrical risk. Case report: Female patient, 29 years old, 99 kg, 167 cm, BMI 35.4 kg.m−2, physical status ASA III, with 27 weeks of gestational age and diagnosis of Klippel-Trenaunay syndrome. She was admitted to attempt inhibition of preterm labor. As manifestations of Klippel-Trenaunay syndrome, the patient presented with cerebral and cutaneous hemangioma mainly in the trunk and lumbar region, paresis in the left upper and lower limbs, and limb asymmetry requiring the use of a walking stick. Physical examination revealed absence of airway vascular malformations and Mallampati class 3. Laboratory tests were normal and abdominal angiotomography showed irregular uterus, with multiple varices and vessels of arterial origin and bilateral periadnexal varices. She evolved with failure in preterm labor inhibition, and cesarean section under total intravenous anesthesia was indicated. Monitoring, central and peripheral venous access, radial artery catheterization, and diuresis were secured. Cesarean section was performed with median incision and longitudinal uterine body section for fetal extraction. Two episodes of arterial hypotension were seen intraoperatively. The postoperative evolution was uneventful. The choice of anesthesia was dependent on the clinical manifestations and the lack of imaging tests proving the absence of neuraxial hemangiomas.

Resumo Introdução: A síndrome de Klippel-Trenaunay é uma doença vascular congênita rara caracterizada por hemangiomas cutâneos, varicosidades e assimetria de membros, que pode evoluir com distúrbios de coagulação e hemorragia como complicações mais frequentes na paciente grávida. A gestação é desaconselhada nas mulheres portadoras dessa síndrome devido ao aumentado risco obstétrico. Relato de caso: Paciente com 29 anos, 99 kg e 167 cm, IMC 35,4 kg.m-2, estado físico ASA III, com 27 semanas de idade gestacional, com diagnóstico de síndrome de Klippel-Trenaunay, foi internada para tentativa de inibição de trabalho de parto prematuro. Como manifestações da síndrome de Klippel-Trenaunay apresentava hemangiomas cerebral e cutâneos, principalmente em tronco e região lombar, paresia em membros superior e inferior esquerdos e assimetria de membros, necessitando de bengala para locomoção. Ao exame físico: ausência de malformações vasculares em vias aéreas, escore 3 pela classificação de Mallampati; exames laboratoriais normais; angiotomografia computadorizada de abdômen mostrava útero irregular, com múltiplas varizes e vasos de permeio de origem arterial e varizes perianexiais bilaterais. Evoluiu com falha de inibição do trabalho de parto prematuro e foi indicada a cesariana sob anestesia geral venosa total. Monitoração, acesso venoso central e periférico, cateterização de artéria radial, diurese. Operação cesariana com incisão mediana e secção corporal longitudinal uterina para extração fetal. No intraoperatório, observaram-se dois episódios de hipotensão arterial. A evolução pós-operatória seguiu sem complicações ou intercorrências. A escolha da anestesia dependeu das manifestações clínicas e da falta de exames de imagem que comprovassem a ausência de hemangiomas no neuroeixo.
