ABSTRACT

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

ABSTRACT

A gestação ectópica em cicatriz de cesariana prévia é um evento iatrogênico raro, que vem crescendo junto com o aumento das taxas de cesariana. Ela não exi- be manifestação clínica específica, o que dificulta o diagnóstico e não apresenta tratamento preconizado, embora esteja associada a grandes complicações obsté- tricas como hemorragia incoercível, acretismo placentário e rotura uterina. Dessa forma, o presente artigo relata três casos clínicos em que diferentes tratamentos foram propostos, objetivando discutir algumas possibilidades terapêuticas como a aspiração manual intrauterina (AMIU) associada com o uso de metotrexato, lapa- roscopia e laparotomia, comparando os resultados encontrados.(AU)


Ectopic cesarean scar pregnancy is a rare iatrogenic event, which has been increase with growing in the percentage of cesarean delivery. It does not exhibit specific cli- nical manifestation, making diagnosis difficult and does not have yet recommended treatment, although is associated with major obstetrics complication such incoer- cible hemorrhage, abnormally invasive placenta and uterine rupture. Therefore, the present article reports three clinical cases witch different types of management, ai- ming discuss some possibilities such intrauterine manual aspiration after systemic methotrexate, laparoscopy or laparotomy surgical, comparing results.(AU)

ABSTRACT

Abstract A cesarean scar pregnancy (CSP) is a scary and life-threatening complication of cesarean section (CS). Nevertheless, the incidence of CS is constantly growing. The CSP incidence is 0,15% of pregnancies after CS which represents 6,1% of all ectopic pregnancies in women with condition after CS. Therefore, it should be more present in the clinical daily routine. From mild nonspecific symptoms to hypovolemic shock, diagnosis and therapy must be performed quickly. With the progressive growth of the scar pregnancy, a uterine rupture involves the risk of severe bleeding, and an emergency hysterectomy could be necessary. Prolongation of pregnancy has been successful only in a few cases.We report 11 cases from our hospital in the past 10 years. In the discussion, treatment options of this complication with an increasing incidence, which is associated with serious morbidity and mortality, are presented based on the current literature. Treatment options include drug therapy, but also surgical or combined procedures with radiological intervention.

ABSTRACT

Abstract Objective Cesarean section (CS) delivery, especially without previous labor, is associated with worse neonatal respiratory outcomes. Some studies comparing neonatal outcomes between term infants exposed and not exposed to antenatal corticosteroids (ACS) before elective CS revealed that ACS appears to decrease the risk of respiratory distress syndrome (RDS), transient tachypnea of the neonate (TTN), admission to the neonatal intensive care unit (NICU), and the length of stay in the NICU. Methods The present retrospective cohort study aimed to compare neonatal outcomes in infants born trough term elective CS exposed and not exposed to ACS. Outcomes included neonatal morbidity at birth, neonatal respiratory morbidity, and general neonatal morbidity. Maternal demographic characteristics and obstetric data were analyzed as possible confounders. Results A total of 334 newborns met the inclusion criteria. One third of the population study (n=129; 38.6%) received ACS. The present study found that the likelihood for RDS (odds ratio [OR]=1.250; 95% confidence interval [CI]: 0.454-3.442), transient TTN (OR=1.,623; 95%CI: 0.556-4.739), and NIUC admission (OR=2.155; 95%CI: 0.474-9.788) was higher in the ACS exposed group, although with no statistical significance. When adjusting for gestational age and arterial hypertension, the likelihood for RDS (OR=0,732; 95%CI: 0.240-2.232), TTN (OR=0.959; 95%CI: 0.297--3.091), and NIUC admission (OR=0,852; 95%CI: 0.161-4.520) become lower in the ACS exposed group. Conclusion Our findings highlight the known association between CS-related respiratory morbidity and gestational age, supporting recent guidelines that advocate postponing elective CSs until 39 weeks of gestational age.

ABSTRACT

Abstract Objective To investigate the effect of closure types of the anterior abdominal wall layers in cesarean section (CS) surgery on early postoperative findings. Methods The present study was designed as a prospective cross-sectional study and was conducted at a university hospital between October 2018 and February 2019. A total of 180 patients who underwent CS for various reasons were enrolled in the study. Each patient was randomly assigned to one of three groups: Both parietal peritoneum and rectus abdominis muscle left open (group 1), parietal peritoneum closure only (group 2), and closure of the parietal peritoneum and reapproximation of rectus muscle (group 3). All patients were compared in terms of postoperative pain scores (while lying down and duringmobilization), analgesia requirement, and return of bowel motility. Results The postoperative pain scores were similar at the 2nd, 6th, 12th, and 18th hours while lying down. During mobilization, the postoperative pain scores at 6 and 12 hours were significantly higher in group 2 than in group 3. Diclofenac use was significantly higher in patients in group 1 than in those in group 2. Meperidine requirements were similar among the groups. There was no difference between the groups' first flatus and stool passage times. Conclusion In the group with only parietal peritoneum closure, the pain scores at the 6th and 12th hours were higher. Rectus abdominismuscle reapproximations were found not to increase the pain score. The closure of the anterior abdominal wall had no effect on the return of bowel motility.

ABSTRACT

Objetivo: Descrever o perfil epidemiológico e microbiológico das puérperas com diagnóstico de infecção após cesárea, caracterizando as infecções de sítio cirúrgico e o tratamento. Métodos: Coorte prospectiva de parturientes submetidas a parto cesáreo em maternidade pública de Manaus, Amazonas, Brasil, com diagnóstico de infecção de sítio cirúrgico, entre 1º de julho de 2019 e 30 de abril de 2020. Foram coletados dados epidemiológicos. Para a investigação do perfil microbiológico, foi realizada a identificação da cultura a partir da secreção da infecção do sítio cirúrgico e do antibiograma das culturas. Resultados: Um total de 81 pacientes foi diagnosticado com infecção de sítio cirúrgico durante o período de estudo. A taxa de infecção de sítio cirúrgico na maternidade em estudo foi de 6,0%. As pacientes possuíam baixa escolaridade e baixa renda mensal, com ocupações que requerem menor qualificação, sendo a maioria solteira. Entre as pacientes, 70,4% eram obesas e 28,4% apresentaram sobrepeso; 45,6% delas tiveram parto cesáreo de emergência e 29,6% não usaram antibióticos profiláticos. Staphylococcus aureus foi a cultura identificada mais frequentemente e apresentou resistência ao antibiótico mais prescrito: a gentamicina. Conclusão: A taxa de infecção do sítio cirúrgico foi alta durante o período do estudo. Ressaltamos a necessidade de um protocolo eficaz de identificação bacteriana e acompanhamento da puérpera. O conhecimento das características epidemiológicas e microbiológicas pode auxiliar no planejamento dos cuidados realizados pelas instituições de saúde para minimizar os casos de infecção de sítio cirúrgico e suas consequências.(AU)


Objective: To describe the epidemiological and microbiological profiles of puerperal women diagnosed with the infection after cesarean sections, characterizing the surgical site infections and treatment. Methods: Prospective cohort of parturients underwent cesarean delivery at a public maternity hospital in Manaus, Amazonas, Brazil, diagnosed with surgical site infection between July 1, 2019, and April 30, 2020. Epidemiological data were collected. To investigate the microbiological profile, both culture identification from surgical site infection secretion and antibiogram for the cultures were performed. Results: A total of 81 patients were confirmed to have surgical site infection during this study period; The surgical site infection rate in the maternity hospital under study was 6.0%. The patients presented a low level of education and monthly income, with occupations that require lower qualification, and most of them are single. Seventy point four percent of the patients were obese, and 28.4% were overweight. Forty-five point six percent of patients had an emergency cesarean delivery, and 29.6% did not use prophylactic antibiotics. Staphylococcus aureus was the most frequent culture identified from surgical site infection secretion and presented resistance to the most prescribed antibiotic, Gentamicin. Conclusion: The rate of surgical site infection was high during the study period. We highlight the need for an effective bacterial identification protocol and monitoring of puerperal women. Knowledge of epidemiological and microbiological characteristics can assist in the planning of care performed by the health institutions to minimize cases of surgical site infection and its consequences.(AU)

ABSTRACT

BACKGROUND@#Hypotension is a common complication caused by spinal anesthesia (SA), which may have adverse impacts on the condition of the parturient and fetus. Liquid infusion was found to be relatively effective for reducing the incidence of hypotension. However, the question of whether colloid preload can optimize hemodynamic variables in the cesarean section remains controversial. This study aims to determine the effects of colloid preload on the incidence of hypotension induced by SA in elective cesarean section.@*METHODS@#Related keywords were searched on PubMed, EMBASE, and Cochrane Library from inception dates to May 2020. Studies included were evaluated for eligibility and quality. The primary outcome was the intra-operative incidence of hypotension and severe hypotension. The secondary outcomes included the lowest intra-operative systolic blood pressure, the maximal intra-operative heart rate, the intra-operative needs of ephedrine and phenylephrine, the incidence of maternal nausea and/or vomiting, and neonatal outcomes (umbilical artery pH and Apgar scores). Apart from the above, RevMan 5.3 was used for the data analysis.@*RESULTS@#Altogether nine randomized controlled trials were included in the meta-analysis. There were no significant differences in the incidence of intra-operative hypotension, severe hypotension, or neonatal outcomes between the colloid preload group and control group, except for the umbilical artery pH.@*CONCLUSION@#This meta-analysis suggests that colloid preload does not significantly reduce the incidence of hypotension associated with SA in elective cesarean section.

ABSTRACT

BACKGROUND@#Norepinephrine infusion decreases hypotension after spinal anesthesia during cesarean section. This study aimed to compare the efficacy of norepinephrine infusion and ephedrine bolus against post-spinal hypotension in parturients.@*METHODS@#In this double-blinded, randomized controlled clinical trial, parturients scheduled for elective cesarean section were randomly allocated to receive norepinephrine infusion (0.05 μg·kg-1·min-1) just before spinal anesthesia continuing for 30 min or ephedrine bolus (0.15 mg/kg) just before spinal anesthesia. A rescue bolus (5 μg norepinephrine for the norepinephrine group, and 5 mg ephedrine for the ephedrine group) was administered whenever hypotension occurred. Our primary outcome was the incidence of hypotension within 30 min of spinal anesthesia administration. Secondary outcomes included maternal and neonatal outcomes 30 min after spinal block, and neonatal cerebral oxygenation 10 min after birth.@*RESULTS@#In total, 190 patients were enrolled; of these patients, 177 were included in the final analysis. Fewer patients suffered hypotension in the norepinephrine group than in the ephedrine group (29.5% vs. 44.9%, odds ratio [OR]: 0.51, 95% confidence interval [CI]: 0.28-0.95, P = 0.034). Moreover, the tachycardia frequency was lower in the norepinephrine group than in the ephedrine group (OR: 0.22, 95% CI: 0.11-0.44, P < 0.001), and patients suffered less nausea and vomiting (OR: 0.28, 95% CI: 0.11-0.70, P = 0.004). There was no difference in Apgar scores and umbilical arterial blood gas analysis between the two groups. However, neonatal cerebral regional saturations were significantly higher after birth in the norepinephrine group than in the ephedrine group (mean difference: 2.0%, 95% CI: 0.55%-3.45%, P = 0.008).@*CONCLUSION@#In patients undergoing elective cesarean section with spinal anesthesia, norepinephrine infusion compared to ephedrine bolus resulted in less hypotension and tachycardia, and exhibited potential neonatal benefits.@*TRIAL REGISTRATION@#ClinicalTrials.gov, NCT02542748; https://clinicaltrials.gov/ct2/show/record/NCT02542748.

ABSTRACT

Abstract: The aim of this study was to analyze the association between birth by cesarean section and central adiposity in adolescents in São Luís, Maranhão State, Brazil. This was a cohort study that included 601 participants evaluated at birth and at 18-19 years. At birth we assessed type of delivery, maternal education, family income, maternal marital status, maternal body mass index before pregnancy, prenatal care, maternal smoking habit, gestational age at delivery and intrauterine growth restriction. In the adolescents, we evaluated central adiposity using the dual X-ray energy absorptiometry method. The indicators of central fat used were the trunk-to-total fat mass ratio (T/T), the android-to-gynoid fat mass ratio (A/G), the trunk-to-limb fat mass ratio (T/Lb), and the trunk-to-leg fat mass ratio (T/Lg). A theoretical model for the study of associations was developed using directed acyclic graphs, which allowed selecting the variables that required minimum adjustment for inclusion in the predictive model of exposure to cesarean delivery. The data were analyzed with marginal structural models weighted by the inverse of the probability of selection. A total of 38.6% of the adolescents studied were delivered by cesarean section. There was no significant difference in the central adiposity of adolescents delivered by cesarean section according to the indicators used: T/T ( coefficient = -0.003; 95%CI: -0.013; 0.007), A/G (coefficient = 0.001; 95%CI: -0.015; 0.018); T/Lb (coefficient = -0.016; 95%CI: -0.048; 0.016); T/Lg (coefficient = 0.014; 95%CI: -0.060; 0.030). In conclusion, there was no association between cesarean section delivery and greater central adiposity in the studied adolescents.


Resumo: O estudo teve como objetivo analisar a associação entre nascimento por parto cesáreo e adiposidade central em adolescentes em São Luís, Maranhão, Brasil. O estudo de coorte incluiu 601 participantes avaliados ao nascer e com 18-19 anos de idade. Ao nascer, foram avaliados o tipo de parto, escolaridade materna, renda familiar, estado civil materno, índice de massa corporal pré-gestacional, atendimento pré-natal, tabagismo materno, idade gestacional ao nascer e restrição do crescimento intrauterino. Nos adolescentes, a adiposidade central foi avaliada com o método da absorciometria de raios-X de dupla energia. Como indicadores da adiposidade central, foram usadas a razão gordura tronco/gordura total (T/T), razão gordura androide/gordura ginecoide (A/G), razão gordura tronco/gordura membros (T/Lb) e razão gordura tronco/gordura membros inferiores (T/Lg). Foi desenvolvido um modelo teórico para analisar as associações, usando gráficos acíclicos dirigidos, permitindo a seleção das variáveis que exigiam ajuste mínimo para inclusão no modelo preditivo de exposição ao parto cesáreo. Os dados foram analisados com modelos estruturais marginais, ponderados pelo inverso da probabilidade de seleção. Entre os adolescentes estudados, 38,6% nasceram de parto cesáreo. Não houve diferença significativa na adiposidade central nos adolescentes nascidos de parto cesáreo, de acordo com os indicadores utilizados: T/T (coeficiente = -0,003; IC95%: -0,013; 0,007), A/G (coeficiente = 0,001; IC95%: -0,015; 0,018); T/Lb (coeficiente = -0,016; IC95%: -0,048; 0,016); T/Lg (coeficiente = 0,014; IC95%: -0,060; 0,030), O estudo conclui que não havia associação entre história de parto cesáreo e aumento de adiposidade central nesse grupo de adolescentes.


Resumen: El objetivo de esta investigación fue estudiar la asociación entre el nacimiento por parto con cesárea y la adiposidad central en adolescentes en São Luís, Maranhão, Brasil. La cohorte de estudio incluyó a 601 participantes evaluados en su nacimiento y con 18-19 años de edad. En el momento del nacimiento se evaluó el tipo de parto, educación de la madre, ingresos familiares, estado civil de la madre, índice de masa corporal de la madre, cuidado prenatal, madre fumadora, edad gestacional en el parto y restricción del crecimiento intrauterino. En los adolescentes, la grasa central se evaluó usando el método de absorciometría con rayos X de energía dual. Los indicadores de grasa central utilizados fueron: el cociente de torso-grasa total (T/T por sus siglas en inglés), el de androide/ginecoide de grasa corporal (A/G), el cociente de masa adiposa torso-extremidades (T/Lb por sus siglas en inglés), y el cociente de masa adiposa torso-pierna (T/Lg por sus siglas en inglés). Se desarrolló un modelo teórico para el estudio de asociaciones, usando grafos acíclicos dirigidos, lo que permitió seleccionar las variables que requerían un mínimo ajuste para su inclusión en el modelo predictivo de exposición al parto por cesárea. Los datos se analizaron con modelos estructurales marginales ponderados por el inverso de la probabilidad de selección. De los adolescentes estudiados, un 38,6% fueron partos por cesárea. No hubo una diferencia significativa en la adiposidad central de los adolescentes que nacieron por cesárea, según los indicadores usados: T/T (coeficiente = -0,003; 95%CI: -0,013; 0,007), A/G (coeficiente = 0,001; 95%CI: -0,015; 0,018); T/Lb (coeficiente = -0,016; 95%CI: -0,048; 0,016); T/Lg (coeficiente = 0,014; 95%CI: -0,060; 0,030). A modo de conclusión, no hubo asociación entre los partos por cesárea y una mayor adiposidad central en los adolescentes estudiados.

ABSTRACT

La presencia de elementos extraños dentro del canal raquídeo es infrecuente y no hay claro consenso respecto de su tratamiento. Las publicaciones sobre fragmentos de proyectil de arma de fuego intracanal recomiendan la exéresis de los fragmentos ante la posibilidad de migración, sobre todo, cuando están en una zona próxima al cono medular. Se debería proceder del mismo modo ante una aguja dentro del canal espinal. Presentamos a una paciente con dolor radicular invalidante provocado por un fragmento de aguja dentro del canal espinal luego de una cesárea. Nivel de Evidencia: IV


The presence of foreign elements within the spinal canal is rare and there is no clear consensus regarding its treatment. The publications on intracanal firearm projectile fragments recommend exeresis of the fragments due to the possibility of migration, especially when they are in an area close to the medullary cone. The same procedure should be applied to a needle inside the spinal canal. We present a patient with disabling radicular pain caused by a needle fragment within the spinal canal after cesarean section. Level of Evidence: IV

ABSTRACT

Abstract Background: Postoperative Nausea and Vomiting (PONV) risk factors have not been defined for obstetric patients. In this study, our objective was to identify potential risk factors for PONV after cesarean sections performed under spinal anesthesia. Methods: One cohort of patients submitted to cesarean under spinal anesthesia was used to investigate potential risk factors for PONV. The best numerical risk factors were dichotomized using chi-squared method. A conditional independence (incremental association method) casual network was used to select the best predictors for PONV. Results: Two hundred and fifty of 260 patients remained in the study. Odds ratio for PONV of younger maternal age (< 25 years: 2.9 [1.49−5.96]), lower spinal bupivacaine dose (< 13 mg, inf [2.4-inf]), lower spinal morphine dose (< 80 mg, 0.03 [0−0.97]), history of motion sickness (2.5 [1.27−5.25]), significant nausea during the first trimester (0.3 [0.16−0.64]), intraoperative nausea and vomiting (8.2 [3.67−20.47]), and lower gestational age (< 38 weeks, 2.0 [1.01−4.08]) were statistically significant. The causal network selected absence of significant nausea during the first gestational trimester, intraoperative nausea, and gestational age < 38 weeks as the main direct risk factors for PONV. Conclusions: Intraoperative nausea and maternal age < 25 years were the main risk factors for PONV after cesareans under spinal anesthesia. Absence of self-reported nausea during the first trimester was a protective factor for post-cesarean nausea and vomiting.


Resumo Introdução: Os fatores de risco para náusea e vômitos pós-operatórios (NVPO) ainda não foram definidos para pacientes de obstetrícia. Neste estudo, nosso objetivo foi identificar potenciais fatores de risco para NVPO após parto cesariano realizado sob raquianestesia. Método: Uma coorte de pacientes submetidas a cesariana sob raquianestesia foi usada para investigar potenciais fatores de risco para NVPO. Os melhores fatores de risco numéricos foram dicotomizados por meio do método qui-quadrado. Uma rede casual de independência condicional (método de associação adicional) foi usada para selecionar os melhores preditores de NVPO. Resultados: Das 260 pacientes iniciais, 250 completaram o estudo. A razão de chances para NVPO foi estatisticamente significante para menor idade materna (< 25 anos: 2,9 [1,49−5,96]), dose mais baixa de bupivacaina raquidiana (< 13 mg, inf [2,4-inf]), dose mais baixa de morfina raquidiana (< 80 mg, 0,03 [0−0,97]), histórico de enjoo de movimento (2,5 [1,27−5,25]), náuseas importantes durante o primeiro trimestre (0,3 [0,16−0,64]), náusea e vômitos intraoperatórios (8,2 [3,67−20,47]) e menor idade gestacional (< 38 semanas, 2,0 [1,01−4,08]). A rede causal selecionou ausência de náuseas significativas durante o primeiro trimestre gestacional, náusea intraoperatória e idade gestacional < 38 semanas como os principais fatores de risco diretos para NVPO. Conclusões: Náusea intraoperatória e idade materna < 25 anos foram os principais fatores de risco para NVPO após cesariana sob raquianestesia. A ausência de náusea autorreferida durante o primeiro trimestre foi um fator protetor para náusea e vômitos após cesariana.

ABSTRACT

Abstract Background and objectives: Limited data are present on safety and efficiency of epinephrine for the prophylaxis and treatment of spinal-hypotension. This study was conducted to compare the effect of epinephrine with norepinephrine and phenylephrine on the treatment of spinal-hypotension and ephedrine requirement during cesarean delivery. Methods: One hundred and sixty parturients with uncomplicated pregnancies undergoing elective cesarean delivery under spinal anesthesia were recruited. They were allocated randomly to receive norepinephrine 5 µg.mL−1 (n = 40), epinephrine 5 µg.mL−1 (n = 40), phenylephrine 100 µg.mL−1 (n = 40) or 0.9% saline infusions (n = 40) immediately after induction of spinal anesthesia. Whenever systolic blood pressure drops to less than 80% of baseline, 5 mg of intravenous ephedrine was administered as rescue vasopressor. The incidence of hypotension, total number of hypotension episodes, the number of patients requiring ephedrine, the mean amount of ephedrine consumption and side effects were recorded. Results: There was no statistically significant difference in incidence of maternal hypotension between groups. The number of patients requiring ephedrine was significantly greater in group saline than in group phenylephrine (p< 0.001). However, it was similar between phenylephrine, norepinephrine, and epinephrine groups. The mean ephedrine consumption was significantly higher in group saline than in norepinephrine, epinephrine, phenylephrine groups (p= 0.001). Conclusion: There is no statistically significant difference in incidence of hypotension and ephedrine consumption during spinal anesthesia for cesarean delivery with the use of epinephrine when compared to norepinephrine or phenylephrine. Epinephrine can be considered an alternative agent for management of spinal hypotension.


Resumo Justificativa e objetivos: Existem dados limitados sobre segurança e eficiência da epinefrina na profilaxia e tratamento da hipotensão arterial associada à raquianestesia. O presente estudo foi realizado para comparar o efeito da epinefrina com norepinefrina e fenilefrina no tratamento da hipotensão após raquianestesia e necessidade de efedrina durante o parto cesáreo. Método: Foram recrutadas 160 parturientes com gestações não complicadas, submetidas a cesariana eletiva sob raquianestesia. Elas foram alocadas aleatoriamente para receber norepinefrina 5 µg.mL-1 (n = 40), epinefrina 5 µg.mL-1 (n = 40), fenilefrina 100 µg.mL-1 (n = 40) ou infusão de solução fisiológica NaCl a 0,9% (n = 40) imediatamente após a indução da raquianestesia. Sempre que houvesse redução da pressão arterial sistólica para valor inferior a 80% da linha de base, 5 mg de efedrina iv eram administrados como vasopressor de resgate. A incidência de hipotensão, o número total de episódios de hipotensão, o número de pacientes que necessitaram de efedrina, o consumo médio de efedrina e os efeitos colaterais foram registrados. Resultados: Não houve diferença estatisticamente significante na incidência de hipotensão materna entre os grupos. O número de pacientes que necessitaram de efedrina foi significantemente maior no grupo solução fisiológica do que no grupo fenilefrina (p< 0,001). No entanto, foi semelhante entre os grupos fenilefrina, norepinefrina e epinefrina. O consumo médio de efedrina foi significantemente maior no grupo solução fisiológica do que nos grupos norepinefrina, epinefrina e fenilefrina (p = 0,001). Conclusão: Não houve diferença estatisticamente significante na incidência de hipotensão e consumo de efedrina durante raquianestesia para parto cesáreo com uso de epinefrina quando comparada à norepinefrina ou fenilefrina. A epinefrina pode ser considerada como agente alternativo para o tratamento da hipotensão após raquianestesia.

ABSTRACT

Abstract Objectives: to verify the effects of elective cesarean sections on perinatal outcomes and care practices, as compared to vaginal deliveries. Methods: cohort study with 591 mothers and their babies, developed in a medium-sized city in the state of São Paulo, Brazil. Data were collected from hospital records and by interviews at the neonatal screening unit in the city from July 2015 to February 2016. Data regarding childbirth, newborns, sociodemography, and current gestational history were obtained from each mother. The associations of interest were evaluated with Cox regression analyses adjusted for the covariates identified through the results of bivariate analyses presenting a statistical significance level ofp<0.20. In adjusted analyzes, relationships were considered significant ifp<0.05, with relative risk being considered as the measure of effect. Results: if compared to women who had vaginal deliveries, those who were submitted to elective cesarean sections were at a higher risk of not having skin-to-skin contact with their babies in the delivery room, of not breastfeeding in the first hour of life, and of having their babies hospitalized in a neonatal unit. Conclusions: reducing the number of elective cesarean sections is essential to foster good neonatal care practices and reduce negative neonatal outcomes.


Resumo Objetivos: verificar os efeitos da cesárea eletiva, em comparação ao parto vaginal, sobre os desfechos perinatais e práticas de cuidado. Métodos: estudo de coorte com 591 mães e seus bebês, desenvolvido em município do interior paulista. Os dados foram coletados do prontuário hospitalar e por entrevista na unidade de triagem neonatal do município, de julho de 2015 a fevereiro de 2016. Foram obtidos dados relativos ao parto, ao recém-nascido, à sociodemografia e à história gestacional atual. As associações de interesse foram avaliadas com análises de regressão de Cox ajustadas para as covariáveis identificadas, considerando-se para tal, resultados de análises bivariadas que apresentaram significância estatística em nível dep<0,20. Nas análises ajustadas, relações foram consideradas significativas se p<0,05, tendo como medida de efeito o risco relativo. Resultados: mulheres submetidas à cesárea eletiva, em comparação àquelas que tiveram parto vaginal, apresentaram maior risco de não terem contato pele a pele com seus bebês na sala de parto, de não amamentarem na primeira hora de vida e de terem seus bebês internados em unidade neonatal. Conclusões: reduzir a taxa de cesárea eletiva é fundamental para que haja aumento na frequência de boas práticas de cuidado neonatal e redução de desfechos neonatais negativos.

ABSTRACT

RESUMEN El parto vaginal se asocia con un riesgo más alto de daño perineal, incontinencia urinaria y fecal comparado con el parto cesárea. Dicho riesgo aumenta con el parto instrumental (ej. fórceps) y disminuye cuando la posición al momento del parto reduce la compresión sobre el sacro o si el parto ocurre bajo el agua. En otros factores que aumentan el riesgo de incontinencia se incluyen: la gran multiparidad, la duración del trabajo de parto, el peso fetal y tamaño de su cabeza, la edad muy joven al momento del primer parto, la inducción del trabajo de parto, la obesidad, la diabetes, la constipación, el tabaquismo y la historia de incontinencia urinaria o fecal. Factores sociales que se asocian a incontinencia incluyen la falta de educación, malas condiciones de hábitat, trabajo manual intenso, la falta de actividad física y el divorcio.


ABSTRACT Vaginal delivery is associated with a higher risk of perineal injury, and urinary and fecal incontinence as compared with caesarean delivery; The risk is higher in case of operative vaginal delivery and lower if the position at delivery takes the weight off the sacrum or is carried out under water immersion; A number of other factors increase the risk of incontinence, including higher parity, duration of labour, fetal weight or size of fetal head, younger age at first delivery, induction of labour, obesity, diabetes, constipation, smoking and history of urinary or fecal incontinence. Social factors such as lack of education, poor living environment, intense manual labour, the absence of physical exercise and divorce, are also associated with incontinence.

ABSTRACT

ABSTRACT Objective: to study the characteristics of women undergoing abdominal surgery with suspected abdominal wall endometriosis or abdominal wall tumor, and to assess the association with age, race and previous cesarean delivery. Method: retrospective and analytical study carried out from January 2000 to December 2019, at the General Surgery Service of Hospital Universitário Antônio Pedro (HUAP) at Universidade Federal Fluminense (UFF). Medical records of 100 patients with abdominal wall endometriosis and other types of abdominal wall tumors were analyzed. Age, color, previous history of cesarean section or abdominal surgery and histopathological data were verified. The patients were classified as young adults (aged between 18 and 28 years and 11 months) and adults. The SPSS program was used for data analysis, Fisher's test with a significance level of 0.05. Results: abdominal wall endometriosis with histopathological confirmation was found in 22%, the mean age was 52.28 ± 18.66 which was lower when compared to other diagnoses. There was an association between previous cesarean section and abdominal wall endometriosis (p <0.005). Conclusion: the women with a diagnosis of abdominal wall endometriosis had undergone previous cesareans (the majority) and were in an active reproductive age. Although the brown skin women were the most frequent, there was no statistical difference.


RESUMO Objetivo: estudar o perfil das mulheres submetidas a cirurgia abdominal com suspeita de endometriose de parede abdominal ou tumor de parede abdominal e analisar a associação com a faixa etária, cor e cesariana prévia. Métodos: estudo retrospectivo e analítico realizado no período de janeiro de 2000 a dezembro de 2019, no Serviço de Cirurgia Geral do Hospital Universitário Antônio Pedro (HUAP) da Universidade Federal Fluminense (UFF). Analisaram-se prontuários de 100 pacientes com endometriose de parede abdominal e com outros tipos de tumoração de parede abdominal. Idade, cor, histórico prévio de cesariana ou cirurgia abdominal e resultado histopatológico foram avaliados. As pacientes foram classificadas em adultas jovem (idade entre 18 e 28 anos e 11 meses) e adultas. Utilizou-se para a análise dos dados o programa SPSS e, teste de Fisher com nível de significância de 0,05. Resultados: Endometriose de parede abdominal com confirmação histopatológica foi encontrada em 22% dos casos. A média de idade foi 52.28 ±18,66, menor quando comparada a outros diagnósticos. Observou-se associação entre cesariana prévia e endometriose de parede abdominal (p<0,005). Conclusão: as mulheres atendidas pelo Setor de Cirurgia da UFF com diagnóstico de endometriose de parede abdominal, na maioria, realizaram cesariana prévia e estavam em idade ativa, reprodutiva. Apesar da cor parda ter sido mais frequente, não se observou diferença estatística.

ABSTRACT

OBJECTIVES: The aim of this study was to determine whether a restrictive compared to a liberal fluid therapy will increase postoperative acute kidney injury (AKI) in patients with severe preeclampsia. METHODS: A total of 46 patients (mean age, 32 years; standard deviation, 6.8 years) with severe preeclampsia were randomized to liberal (1500 ml of lactated Ringer's, n=23) or restrictive (250 ml of lactated Ringer's, n=23) intravenous fluid regimen during cesarean section. The primary outcome was the development of a postoperative renal dysfunction defined by AKI Network stage ≥1. Serum cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) were evaluated at postoperative days 1 and 2. ClinicalTrials.gov: NCT02214186. RESULTS: The rate of postoperative AKI was 43.5% in the liberal fluid group and 43.5% in the restrictive fluid group (p=1.0). Intraoperative urine output was higher in the liberal (116 ml/h, IQR 69-191) than in the restrictive fluid group (80 ml/h, IQR 37-110, p<0.05). In both groups, serum cystatin C did not change from postoperative day 1 compared to the preoperative period and significantly decreased on postoperative day 2 compared to postoperative day 1 (p<0.05). In the restrictive fluid group, NGAL levels increased on postoperative day 1 compared to the preoperative period (p<0.05) and decreased on postoperative day 2 compared to postoperative day 1 (p<0.05). CONCLUSION: Among patients with severe preeclampsia, a restrictive fluid regimen during cesarean section was not associated with increased postoperative AKI.

ABSTRACT

Resumen INTRODUCCIÓN La cesárea es el procedimiento quirúrgico que se realiza con el fin de obtener el nacimiento de un feto, con el objetivo de disminuir la morbimortalidad materna y perinatal asociada con el momento del nacimiento cuando el parto vaginal podría traer consigo complicaciones. En los últimos 30 años la incidencia de la cesárea se ha incrementado significativamente en casi todos los países occidentales, con valores que superan el 15% al 35%, este procedimiento está asociado a varias complicaciones, entre las más frecuentes se encuentran: infecciones, hemorragia obstétrica, histerectomía periparto, necesidad de unidad de cuidados intensivos y acretismo placentario. OBJETIVO Determinar la prevalencia de complicaciones quirúrgicas en pacientes sometidas a cesárea en un Hospital de alta complejidad y explorar factores asociados. MATERIALES Y MÉTODOS Estudio de prevalencia con análisis secundario en el que se incluyeron historias clínicas de pacientes sometidas a cesárea de urgencias y programadas. La variable resultado fue la complicación reportada durante un periodo menor a 30 días. Se tomó el universo, se recolectaron variables sociodemográficas, biológicas y clínicas. Para determinar la prevalencia se tomó como numerador el total de complicaciones y como denominador el total de historias analizadas, para explorar los factores asociados se utilizó el Odds Ratio como medida de asociación con un intervalo de confianza al 95%. RESULTADOS En 899 historias clínicas analizadas se encontró una prevalencia de complicaciones del 5.22% (IC95%: 3.86-6.89), dentro de los factores asociados positivamente se encontró tener una gestación pretermino (OR: 2.05, IC95%: 1.01-4.02); tener al menos una comorbilidad (OR: 2.51, IC 95%: 1.17-5.98) y la prioridad clasificada como urgente (OR: 3.01, IC 95%: 1.07-11.65). CONCLUSIONES La prevalencia encontrada en esta institución es similar a la de la mayor parte de los estudios publicados. El ser un procedimiento de urgencia, la presencia de comorbilidades siendo la preeclampsia la principal y el embarazo pretermino fueron los factores asociados positivamente con complicaciones, las más frecuentes fueron el requerimiento de transfusión, hemorragia, hematoma, la dehiscencia de sutura y la infección de sitio operatorio.


SUMMARY INTRODUCTION Caesarean section is the surgical procedure that is performed in order to obtain the birth of a fetus, with the aim of reducing maternal and perinatal morbidity and mortality associated with the time of birth when vaginal delivery could lead to complications. Last 30 years the incidence of caesarean section has increased significantly in almost all western countries, with values exceeding 15% to 35%, this procedure is associated with several complications, among the most frequent are: infections, obstetric hemorrhage, peripartum hysterectomy, need for intensive care unit and placental acretism. OBJECTIVE To determine the prevalence of surgical complications in patients undergoing caesarean section in a hospital of high complexity and explore associated factors. MATERIALS AND METHODS Prevalence study with secondary analysis, which included clinical records of patients undergoing emergency caesarean section and scheduled. The outcome variable was the complication reported for a period of less than 30 days. The universe was taken, sociodemographic, biological and clinical variables were collected. To determine the prevalence, the total number of complications was taken as a numerator and as the denominator the total of analyzed stories, to explore the associated factors the Odds Ratio was used as a measure of association with a 95% confidence interval. RESULTS In 899 clinical histories analyzed a prevalence of complications of 5.22% was found (95% CI: 3.86-6.89), among the positively associated factors it was found to have a preterm pregnancy (OR: 2.05, 95% CI: 1.01-4.02); have at least one comorbidity (OR: 2.51, 95% CI: 1.17-5.98) and the priority classified as urgent (OR: 3.01, 95% CI: 1.07-11.65). CONCLUSIONS The prevalence found in this institution is similar to that of most of the published studies. Being an emergency procedure, the presence of comorbidities being the main preeclampsia and preterm pregnancy were the factors positively associated with complications, the most frequent were the requirement of transfusion, hemorrhage, hematoma, suture dehiscence, operative and the site infection.

ABSTRACT

SUMMARY An isthmocele, a cesarean scar defect or uterine niche, is any indentation representing myometrial discontinuity or a triangular anechoic defect in the anterior uterine wall, with the base communicating to the uterine cavity, at the site of a previous cesarean section scar. It can be classified as a small or large defect, depending on the wall thickness of the myometrial deficiency. Although usually asymptomatic, its primary symptom is abnormal or postmenstrual bleeding, and chronic pelvic pain may also occur. Infertility, placenta accrete or praevia, scar dehiscence, uterine rupture, and cesarean scar ectopic pregnancy may also appear as complications of this condition. The risk factors of isthmocele proven to date include retroflexed uterus and multiple cesarean sections. Nevertheless, factors such as a lower position of cesarean section, incomplete closure of the hysterotomy, early adhesions of the uterine wall and a genetic predisposition may also contribute to the development of a niche. As there are no definitive criteria for diagnosing an isthmocele, several imaging methods can be used to assess the integrity of the uterine wall and thus diagnose an isthmocele. However, transvaginal ultrasound and saline infusion sonohysterography emerge as specific, sensitive and cost-effective methods to diagnose isthmocele. The treatment includes clinical or surgical management, depending on the size of the defect, the presence of symptoms, the presence of secondary infertility and plans of childbearing. Surgical management includes minimally invasive approaches with sparing techniques such as hysteroscopic, laparoscopic or transvaginal procedures according to the defect size.


RESUMO A istmocele ou nicho uterino é representada por uma descontinuidade miometrial ou um defeito anecoico triangular na parede uterina anterior, com a base se comunicando com a cavidade uterina no local de uma cicatriz anterior de cesárea. O defeito pode ser classificado como pequeno ou grande, dependendo da espessura da parede miometrial deficiente. Embora geralmente assintomático, seu principal sintoma é o sangramento uterino anormal ou pós-menstrual; a dor pélvica crônica também pode ocorrer. Infertilidade, placenta acreta ou prévia, deiscência de cicatriz, ruptura uterina e gravidez ectópica em cicatriz de cesárea prévia também podem aparecer como complicações dessa condição. Os fatores de risco para desenvolvimento da istmocele comprovados até o momento incluem útero retroverso e múltiplas cesarianas. No entanto, fatores como localização mais inferior de uma cesárea prévia, fechamento incompleto da histerotomia, aderências precoces na parede uterina e predisposição genética também podem contribuir para o desenvolvimento de um nicho. Como não existem critérios definitivos para o diagnóstico de uma istmocele, vários métodos de imagem podem ser usados para avaliar a integridade da parede uterina e, assim, diagnosticar uma istmocele. Entretanto, ultrassonografia transvaginal e sono-histerografia com infusão salina surgem como métodos específicos, sensíveis e custo-efetivos para o diagnóstico de istmocele. O tratamento inclui manejo clínico ou cirúrgico, dependendo do tamanho do defeito, da presença de sintomas, da presença de infertilidade secundária e de planos de gravidez. O manejo cirúrgico inclui abordagens minimamente invasivas como histeroscopia, laparoscopia ou transvaginal, de acordo com o tamanho do defeito.
