Deambulación precoz e incidencia de cefalea pospunción dural en paciente obstétrica propuesta para cesárea electiva / Early ambulation and incidence of postdural puncture headache in an obstetric patient proposed for elective cesarean section

Introducción: La cefalea pospunción dural es la complicación más habitual tras la anestesia neuroaxial, y es especialmente frecuente en obstetricia, un hallazgo común en el período posparto. Suele ser una complicación benigna y autolimitada, pero sin tratamiento puede conducir a otras complicaciones más graves. Objetivo: Describir la incidencia de cefalea pospunción dural en las pacientes obstétricas programadas para cesárea electiva con anestesia espinal y su relación con la deambulación precoz. Métodos: Se realizó un estudio observacional descriptivo en una serie de casos (50), todas las pacientes propuestas para cesárea electiva bajo el método anestésico espinal subaracnoideo con trocar calibre 25 en el período comprendido entre mayo a diciembre del 2018. Resultados: De un total de 50 pacientes estudiadas con edades entre 18 y 35 años de edad, al 96 por ciento se le realizó punción única de la duramadre, en todas se utilizó trócar 25, atraumático y ninguna presentó cefalea pospunción dural. Conclusiones: Se concluye que la incidencia de cefalea pospunción dural puede disminuir cuando se utilizan agujas espinales atraumáticas, de pequeño calibre; lo cual facilita también la deambulación temprana de la paciente(AU)

Introduction: Postdural puncture headache is the most common complication following neuraxial anesthesia, and is especially common in obstetrics, a common finding in the postpartum period. It is usually a benign and self-limited complication, but if not treated, it can lead to further serious complications. Objective: To describe the incidence of postdural puncture headache in obstetric patients scheduled for elective cesarean section with spinal anesthesia and its relationship with early ambulation. Methods: A descriptive observational study was carried out in a case series (50) of patients proposed for elective cesarean section under the subarachnoid spinal anesthesia method with 25-gauge trocar in the period from May to December 2018. Results: Out of a total of 50 patients aged 18-35 years who participated in the study, 96 percent underwent single dura mater puncture. In all cases, a 25-gauge trocar was used and none presented postdural puncture headache. Conclusions: The incidence of postdural puncture headache may be concluded to decrease when atraumatic spinal needles of small caliber are used, which also facilitates early ambulation of the patient(AU)

Associação entre a técnica de fechamento uterino na cesárea e a istmocele: uma visão global / Association between uterine closure technique after cesarean and isthmocele: an overview

A istmocele (ou "defeito cicatricial de cesariana") é uma alteração anatômica na parede uterina responsável por formar um "nicho", que é visualizado como uma área hipoecoica por histerografia ou por outros métodos de imagem, devido a uma cicatrização inapropriada de uma cesárea anterior. Essa modificação leva a complicações ginecológicas e obstétricas. Este estudo pretendeu analisar, entre os fatores de risco, a relação da istmocele com a técnica de fechamento uterino, comparando a sutura em camada simples com a dupla. Foi realizada uma revisão de literatura por meio de pesquisa bibliográfica em diferentes bases de dados eletrônicos. Foram encontrados 31 artigos, todavia apenas 13 estudos foram incluídos no presente estudo após avaliação criteriosa. A técnica de fechamento uterino é um dos fatores de risco possível de prevenir, sendo que a sutura em camada simples é associada a maior chance de se desenvolver a istmocele. A sutura de camada simples (ancorada) incluindo o endométrio está relacionada a menor espessura miometrial residual, associada a probabilidade de ruptura uterina e a istmocele, que a camada dupla não ancorada com a exclusão do endométrio.(AU)

The isthmocele is an anatomical alteration in the uterine wall responsible for forming a "niche", which is visualized as a hypoechoic area by hysterography or other imaging methods, due to inappropriate healing of a previous cesarean section. This modification leads to gynecological and obstetric complications. This study aimed to analyze among the risk factors the relation of isthmocele and the uterine closure technique comparing the single- and double-layer suture. It was conducted an electronic based search in different electronic databases. The research led to the retrieval of 31 articles; however only 13 studies were included in the present research after careful reading. The uterine closure technique is one of the possible risk factors to be modified; the single-layer suture is associated with a greater chance of developing isthmocele. The locked single-layer suture including the decidua is related to the decreased residual myometrial thickness, associated with the likelihood of uterine rupture and the isthmocele, than the double-layer unlocked excluding the decidua.(AU)

Principales técnicas quirúrgicas para el médico general / Main surgical techniques for the general practitioner

Existen múltiples técnicas y procedimientos quirúrgicos en la práctica clínica que todo médico general debería conocer y manejar ante una situación de urgencia que involucre la resolución inmediata. El no actuar en una situación emergente, ya sea por inexperiencia o desconocimiento puede poner en riesgo la vida del paciente. Entre estos procedimientos, podemos encontrar las suturas (y sus distintos tipos), la paracentesis, la apendicectomía (abierta y laparoscópica), la punción lumbar y la cesárea. Es por esto que se creó este artículo de educación médica utilizando un método explicativo de las principales técnicas quirúrgicas de forma resumida y concisa, basado en la literatura disponible, con el fin de servir como guía de bolsillo y revisión rápida para estudiantes, internos y médicos que deben enfrentarse a un procedimiento quirúrgico que no puede ser diferido.

There are multiple surgical techniques and procedures in the day to day clinical practice that every general practitioner should know how to do and handle in an emergency situation that requires immediate resolution. Failure to act in an emergent situation, either due to inexperience or ignorance, can put a patient's life at risk. Between these procedures there are sutures (and its variations), paracentesis, appendectomy (open and laparoscopic), lumbar puncture and cesarean delivery. That is why this medical education article was developed using an explicative method of the main surgical techniques in a summarized and concise way, based on the available literature, in order to serve as a pocket guide and quick review for students, interns and doctors who must face a surgical procedure that cannot be deferred.

Conducción anestésica perioperatoria en gestante a término con hipertensión pulmonar idiopática / Perioperative anesthetic management in term pregnant women with idiopathic pulmonary hypertension

Introducción: La hipertensión arterial pulmonar es una enfermedad con una baja incidencia en la gestante, aunque trae consigo una alta mortalidad una vez presentada. Un diagnóstico oportuno y un manejo perioperatorio adecuado minimizan el riesgo de desenlace fatal tanto para la madre como el feto. Objetivo: Describir el comportamiento de la hipertensión arterial pulmonar en la gestante a término y su conducción anestésica. Presentación del caso: Paciente de 23 años, antecedentes de salud, edad gestacional de 35.2 semanas. Luego de presentar dolor de espalda y ardor en el pecho relacionado con el esfuerzo, palpitaciones, disnea y bloqueo de rama derecha en electrocardiograma, se ingresa en UTI con sospecha de tromboembolismo pulmonar, el cual queda descartado tras diagnóstico confirmatorio de hipertensión pulmonar después de realizar angio TAC y ecocardiografía. Se decide realizar cesárea programada bajo técnica regional peridural, sin complicaciones tanto para la madre como el niño. Después de 2 días bajo vigilancia intensiva se traslada a su centro hospitalario de cabecera. Conclusiones: La vía del parto, así como una elección adecuada de la técnica anestésica, puede ser la diferencia entre el éxito y la fatalidad. Las técnicas regionales suelen recomendarse por encima de la técnica de anestesia general siempre que no se presenten contraindicaciones(AU)

Introduction: Pulmonary arterial hypertension is a disease with low incidence in the pregnant woman, although it brings about high mortality once presented. Timely diagnosis and adequate perioeprative management minimize the risk of fatal outcome for both mother and fetus. Objective: To describe pulmonary arterial hypertension and its anesthetic management in the term pregnant woman. Case presentation: 23-year-old female patient, with health history and gestational age of 35.2 weeks. After presenting back pain and chest burning associated with exertion, palpitations, dyspnea and right bundle branch block in the electrocardiogram, the patient was admitted to the intensive care unit with suspected pulmonary thromboembolism, which was ruled out due to the confirmatory diagnosis of pulmonary hypertension after performing computerized tomography angiography and echocardiography. Scheduled cesarean section was decided to be perform using the regional peridural technique, without complications for both the mother and the child. After two days under intensive surveillance, she was transferred to her primary hospital. Conclusions: The route of delivery, as well as an adequate choice of the anesthetic technique, can be the difference between success and fatality. Regional techniques are usually recommended over the general anesthesia technique, as long as there are no contraindications(AU)

Effect of closure of anterior abdominal wall layers on early postoperative findings at cesarean section: A prospective cross-sectional study

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.

Resultado perinatal y obstétrico en embarazadas mayores a 35 años y menores a 15 años: (Estudio descriptivo retrospectivo. realizado en el Departamento de Ginecoobstetricia del hospital General San Juan de Dios) / Perinatal and obstetric outcome in pregnant women older than 35 years and younger than 15 years: (Retrospective descriptive study. Performed in the Department of Gynecology and Obstetrics of the Hospital General San Juan de Dios)

En Guatemala, el embarazo en la adolescencia es un problema social, que repercute seriamente en el desarrollo de los adolescentes. El fenómeno se vincula, directamente, con los factores económicos y, sobre todo, con el acceso a la educación y la información, aspectos que de ser accesibles ayudarían a promover un cambio favorable entre las personas con menos recursos. La edad avanzada en el embarazo representa un factor de riesgo de morbimortalidad materna, perinatal e infantil. Se realizo un Estudio descriptivo retrospectivo, se revisaron las papeletas médicas de todas las pacientes embarazadas que cumplieron con los criterios de inclusión. Dentro del estudio se incluyeron 289 pacientes, se observó mayor prevalencia de pacientes >35 años, respecto a los antecedentes prenatales, la edad gestacional más prevalente fue 37 a 41 semanas, el promedio de número de citas de control prenatal fue de 2.98, las complicaciones más frecuentes fueron infección y trabajo de parto pretérmino. En cuanto a los antecedentes natales, la Cesárea trans peritoneal fue la vía de resolución más prevalente y la asfixia perinatal fue la complicación más frecuente. Se observó asociación estadísticamente significativa entre complicaciones pre, natales y post natales edad materna mayor a 35 años. El hallazgo de sobrepeso y obesidad en pacientes mayores a 35 años se puede asociar con la prevalencia de complicaciones y el bajo promedio del número de controles prenatal. La falta de asociación entre edad materna menor a 15 años y complicaciones puede ser atribuida a que estas pacientes llevan un mejor control prenatal, debido al seguimiento especializado que se cuenta por parte del MSPAS.

In Guatemala, teenage pregnancy is a social problem, which seriously affects the development of adolescents. The phenomenon is directly linked to economic factors and, above all, to access to education and information, aspects that if accessible would help promote a favorable change among people with fewer resources. Advanced age in pregnancy represents a risk factor for maternal, perinatal and infant morbidity and mortality. A retrospective descriptive study was carried out, the medical records of all pregnant patients who met the inclusion criteria were reviewed. The study included 289 patients, a higher prevalence of patients> 35 years of age was observed, with respect to prenatal history, the most prevalent gestational age was 37 to 41 weeks, the average number of prenatal control appointments was 2.98, complications the most frequent were infection and preterm labor. Regarding the natal history, trans peritoneal caesarean section was the most prevalent means of resolution and perinatal asphyxia was the most frequent complication. A statistically significant association was observed between prenatal and postnatal complications, maternal age greater than 35 years. The finding of overweight and obesity in patients older than 35 years can be associated with the prevalence of complications and the low average number of prenatal check-ups. The lack of association be-tween maternal age less than 15 years and complications can be attributed to the fact that these patients have better prenatal control, due to the specialized follow-up provided by the MSPAS.

Fatores associados à escolha da via de parto entre estudantes do curso de Medicina no Sul do Brasil / Factors associated with choice of birth delivery route among medical students in Southern Brazil

Objetivo: Identificar os fatores associados à escolha da via de parto entre estudantes do curso de Medicina em uma universidade no Sul do país. Métodos: Estudo transversal realizado com estudantes de Medicina da Universidade do Sul de Santa Catarina (Unisul) ­ Tubarão, no período de julho a novembro de 2019. Resultados: Fizeram parte da pesquisa 423 alunos, homens e mulheres, dos aproximadamente 600 matriculados no período. A maioria dos alunos considerou o parto vaginal (PV) mais seguro, e 44,1% dos estudantes escolheriam essa via para si/sua companheira. O principal motivo pelo qual os alunos escolheram PV foi a "alta hospitalar precoce", e o principal motivo que levou à escolha de cesariana (PC) foi a "ausência de dor durante o parto". Houve associação entre renda mais baixa e a escolha do PV (p = 0,002). A via de parto pela qual o estudante nasceu também se associou com a que ele escolheria (p = 0,001). Ademais, houve significância estatística entre a via de parto que o aluno considerou mais segura e a que ele de fato escolheria (p = 0,001). Todas as alunas que já tiveram filhos realizaram PC. Conclusão: O fator mais relevante de escolha do PC foi a "ausência de dor durante o parto", enquanto do PV foi "alta hospitalar precoce".(AU)

Objective: To identify the factors associated with the choice of birth delivery route among medical students at a university in the south of Brazil. Methods: Cross-sectional study carried out with medical students from the University of Southern Santa Catarina (Unisul) ­ Tubarão, from July to November 2019. Results: Four hundred twenty three students took part in the research, men and women, out of the approximately 600 enrolled in the period. Most students considered vaginal delivery (VD) to be safer, and 44.1% of students would choose this route for their partner. The main reason why students chose VD was "early hospital discharge", and the main reason that led to the choice of cesarean section (CS) was "no pain during childbirth". There was an association between lower income and the choice of VD (p = 0.002). The route of delivery that the student was born was also associated with the one he would choose (p = 0.001). In addition, there was statistical significance between the route of delivery that the student considered safer with the one he would actually choose (p = 0.001). All female students who already had children underwent CS. Conclusion: The most relevant factor for choosing CS was "no pain during delivery", while for VD was "early hospital discharge".(AU)

The effect of epinephrine for the treatment of spinal-hypotension: comparison with norepinephrine and phenylephrine, clinical trial / O efeito de epinefrina, norepinefrina e fenilefrina no tratamento da hipotensão pós-raquianestesia: estudo clínico comparativo

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.

Coronavirus 2019, thrombocytopenia and HELLP syndrome: association or coincidence? / Coronavírus 2019, trombocitopenia e síndrome HELLP: Associação ou coincidência?

Abstract The present report describes the case of a 31-year-old primigravida, with dichorionic twins at 31 weeks. She presented with history of myalgia, jaundice, and abdominal discomfort. No flu-like symptoms as fever or cough. She was not aware of exposure to COVID-19. Normal blood pressure and O2 saturation. Laboratory tests showed platelet count of 218,000 mm3, alanine aminotransferase (ALT) 558 IU and serum creatinine 2.3 mg/dl. Doppler ultrasound in one twin was compatible with brain sparing. Partial hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome was the hypothesis, and a cesarean section was performed. On day 2, the white-cell count reached 33,730, with decreased consciousness and mild respiratory distress. Tomography revealed both lungs with ground-glass opacities. Swab for COVID-19 polymerase chain reaction (PCR) was positive. Thrombocytopenia in patients with COVID-19 appears to be multifactorial, similar to what occurs in preeclampsia and HELLP syndrome. We assume that the synergism of these pathophysiological mechanisms could accelerate the compromise of maternal conditions and could be a warning to the obstetric practice.

Resumo O presente relato descreve o caso de uma gestante de 31 anos, gemelar dicoriônica com 31 semanas, com queixa de mialgia, icterícia e desconforto abdominal. A paciente não apresentava sintomas gripais como febre ou tosse e não tinha conhecimento de exposição ao COVID-19. Pressão arterial e saturação de oxigênio normais. Os exames laboratoriais apresentaram contagem de plaquetas de 218,000 mm3, ALT 558 IU e creatinina 2.3 mg/dl. Doppler compatível com centralização de um dos fetos. Síndrome de hemolysis, elevated liver enzymes, low platelet count (HELLP) parcial foi a hipótese diagnóstica inicial e a cesariana foi realizada. No segundo dia, a paciente apresentou leucócitos de 33.730 com queda do nível de consciência e desconforto respiratório leve. A tomografia revelou opacidade pulmonar em vidro fosco bilateralmente. A pesquisa de COVID-19 por polymerase chain reaction (PCR)/swab teve resultado positivo. Trombocitopenia em pacientes com COVID-19 é multifatorial, semelhante ao que ocorre na pré-eclâmpsia e na síndrome HELLP. Acreditamos que o sinergismo da fisiopatologia das doenças em questão pode acelerar o comprometimento materno e deve servir de alerta para a prática obstétrica.

Risk factors for post-caesarean nausea and vomiting: a prospective prognostic study / Fatores de risco para náusea e vômitos após cesariana: estudo prognóstico prospectivo

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.

Masa pélvica en la mujer puérpera. Presentación de caso / Pelvic mass in puerperal woman. Case presentation

El término infección puerperal se utiliza para describir cualquier infección bacteriana del aparato genital después del parto. Durante gran parte del siglo XX las infecciones puerperales, la preeclampsia y la hemorragia obstétrica formaron parte de la tríada letal de mortalidad materna. La ecografía, la resonancia magnética y la tomografía axial computarizada son la triada de elección para el diagnóstico del abdomen agudo en el puerperio. El mismo resulta difícil debido a factores intrínsecos y es entonces, cuando el radiólogo adquiere un papel crucial. Se presentó un caso de una mujer de 30 años, con 8 días de habérsele practicado una cesárea con un puerperio inmediato normal. Posteriormente presentó dolor abdominal, fiebre, escalofríos y masa palpable en fosa iliaca izquierda. Se practicaron técnicas de imágenes se plantea una masa ovárica izquierda, se realizó laparotomía exploradora y se concluyó como absceso ovárico (AU).

The term puerperal infection is used to describe any bacterial infection of the genital tract after delivery. During much of the twentieth century puerperal infections, preeclampsia and obstetric hemorrhage were part of the lethal triad of maternal mortality. Ultrasonography, magnetic resonance imaging and computed tomography are the triad of choice for the diagnosis of acute abdomen in the puerperium, which is difficult due to intrinsic factors and it is when radiologist plays a vital role. The authors present the case of a woman, aged 30 years, at the 8th day after undergoing a cesarean section with a normal immediate puerperium, who later presented abdominal pain (AU).

¿Puede el fentanilo intratecal disminuir la aparición de náuseas y vómito en comparación con ondansetrón intravenoso durante cesárea electiva? Revisión sistemática de la literatura y metaanálisis / Can intrathecal fentanyl decrease the occurrence of nausea and vomiting compared with intravenous ondansetron during elective cesarean section? Literature Systematic review and meta-analysis

Elective caesarean section is one of the surgeries with the highest intraoperative incidence of nausea, retching and vomiting (IONV), due, among other causes, to the use of anesthetics during the procedure. Some clinical trials have associated the use of low-dose intrathecal (IT) fentanyl with a lower incidence of nausea, retching and vomiting compared to other anesthetics used during caesarean sections. In this context, the objective of this meta-analysis was to evaluate the decrease in the appearance of nausea and vomiting during elective caesarean section with the application of IT fentanyl when compared with the use of intravenous ondansetron (EV). A systematic search was conducted in the main databases (PubMed, EMBASE, ClinicalTrials.gov, Cochrane Library and Google Scholar) for Randomized Clinical Trials (RCTs) that evaluated the use of IT fentanyl compared to ondansetron EV to decrease the occurrence and incidence of IONV during elective caesarean section. The meta-analysis showed a reduction in the incidence of nausea (RR 0.52, 95% CI 0.29-0.93, P = 0.03), gagging (RR 0.39, 95% CI 0, 18-0.88, P = 0.02) and vomiting (RR 0.26, 95% CI 0.11-0.64, P = 0.003) in the group of patients treated with IT fentanyl compared to the group treated with EV ondansetron. From the results, it is suggested that the administration of 12.5 to 20 µg of IT fentanyl may decrease the incidence of IONV in patients undergoing elective caesarean section, although the importance of more high-quality RCTs is highlighted.

La cesárea electiva es una de las cirugías con mayor incidencia intraoperatoria de náuseas, arcadas y vómito (NAV), debido entre otras causas, al uso de anestésicos durante el procedimiento. Algunos ensayos clínicos han asociado el uso de fentanilo intratecal (IT) a dosis bajas con una menor incidencia de náuseas, arcadas y vómito en comparación con otros anestésicos usados durante las cesáreas. En este contexto el objetivo de este metaanálisis fue evaluar la disminución en la aparición de náuseas y vómito durante cesárea electiva con la aplicación de fentanilo IT al compararlo con el uso de ondansetrón intravenoso (EV). Se realizó una búsqueda sistemática en las principales bases de datos (PubMed, EMBASE, ClinicalTrials.gov, Cochrane Library y Google Scholar) para ensayos clínicos aleatorizados (ECA) que evaluaron el uso del fentanilo IT en comparación con ondansetrón EV para disminuir la aparición e incidencia de IONV durante cesárea electiva. En el metaanálisis se evidenció una reducción en la incidencia de náusea (RR 0,52, 95% IC 0,29-0,93, P = 0,03), arcada (RR 0,39, 95% IC 0,18-0,88, P = 0,02) y vómito (RR 0,26, 95% IC 0,11-0,64, P = 0,003) en el grupo de pacientes tratados con fentanilo IT comparado con el grupo tratado con ondansetrón EV. A partir de los resultados, se sugiere que la administración de 12,5 a 20 µg de fentanilo IT puede disminuir la incidencia de NAV intraoperatorias en pacientes sometidas a cesárea electiva, aunque se resalta la importancia de más ECA de alta calidad.

The effects of remifentanil used during cesarean section on oxidative stress markers in correlation with maternal hemodynamics and neonatal outcome: a randomized controlled trial / Os efeitos do remifentanil sobre os marcadores do estresse oxidativo durante a cesariana, em correlação com a hemodinâmica materna e o desfecho neonatal: um estudo randômico controlado

Abstract Background and objective: Remifentanil is used to attenuate maternal hemodynamic response to intubation and surgical stress during Induction-Delivery period of cesarean section. The goal was to compare the effects of two remifentanil dosing regimens on oxidative stress level, in correlation with its hemodynamic and neonatal effects. Methods: Fifty-one patients, 17 per group, enrolled for elective cesarean section were randomly divided by computer-generated codes into three parallel groups: (A) patients received a 1 µg.kg-1 remifentanil bolus immediately before induction, followed by 0.15 µg.kg-1.min-1 infusion, that was stopped after skin incision; (B) patients received a 1 µg.kg-1 remifentanil bolus immediately before induction; (C) (control), patients did not receive remifentanil until delivery. Maternal venous blood samples were taken at basal time, at extraction and 30 minutes after the end of operation for spectrophotometrical determination of malondialdehyde and advanced oxidation protein products concentration. The same was conducted for umbilical venous sample. Results: Systolic blood pressure and heart rate remained significantly lower in group A compared to B and C during entire Induction-Delivery period (p < 0.001, p = 0.02 after intubation; p = 0.006, p = 0.03 after skin incision; p = 0.029, p = 0.04 after extraction; respectively). Malondialdehyde concentration was lower at time of extraction in maternal blood in group A compared to B and C (p = 0.026). All neonatal Apgar scores were ≥ 8 and umbilical acid-base values within normal range. Conclusions: The remifentanil dosing regimen applied in group A significantly attenuated lipid peroxidation and maternal hemodynamic response during entire I-D period, without compromising neonatal outcome.

Resumo Justificativa e objetivo: O remifentanil é usado para atenuar a resposta hemodinâmica materna à intubação e ao estresse cirúrgico durante o intervalo indução-parto cesariana. O objetivo foi comparar os efeitos de dois regimes posológicos de remifentanil sobre o nível de estresse oxidativo, em correlação com seus efeitos na hemodinâmica materna e no neonato. Métodos: Mediante códigos gerados por computador, 51 pacientes (17 por grupo) programadas para cesariana eletiva foram randomicamente divididas em três grupos paralelos (A, B e C). No Grupo A, as pacientes receberam remifentanil em bolus de 1 µg.kg-1 imediatamente antes da indução, seguido por infusão de 0,15 µg.kg-1.min-1 que foi interrompida após a incisão da pele; no Grupo B, as pacientes receberam remifentanil em bolus de 1 µg.kg-1 imediatamente antes da indução; no Grupo C (controle), as pacientes não receberam remifentanil até o parto. Amostras de sangue venoso materno foram colhidas no momento basal, na extração do feto e 30 minutos após o término da operação para determinar espectrofotometricamente as concentrações do malondialdeído e dos produtos proteicos de oxidação avançada. O mesmo foi feito para a coleta das amostras de sangue venoso umbilical. Resultados: A pressão arterial sistólica e a frequência cardíaca permaneceram significativamente menores no Grupo A, comparado aos grupos B e C, durante todo o intervalo indução-parto (p < 0,001, p = 0,02 após a intubação; p = 0,006, p = 0,03 após a incisão da pele; p = 0,029, p = 0,04 após a extração do feto, respectivamente). No momento da extração do feto, a concentração do malondialdeído foi menor no sangue materno do Grupo A, comparado aos grupos B e C (p = 0,026). Todos os escores de Apgar neonatais foram ≥ 8 e os valores da avaliação ácido-base do cordão umbilical estavam dentro da faixa normal. Conclusões: O regime posológico de remifentanil aplicado ao Grupo A atenuou de modo significativo a peroxidação lipídica e a resposta hemodinâmica materna durante todo o intervalo indução-parto, sem comprometer o desfecho neonatal.

Intermittent loss of consciousness during cesarean section under spinal anesthesia: a case report / Perda intermitente de consciência durante cesariana sob raquianestesia: relato de caso

Abstract Loss of consciousness during spinal anesthesia is a rare but scary complication. This complication is generally related to severe hypotension and bradycardia, but in this case, the loss of consciousness occurred in a hemodynamically stable parturient patient. We present a 31 years-old patient who underwent an emergency cesarean section. She lost consciousness and had apnea that started 10 minutes after successful spinal anesthesia and repeated three times for a total of 25 minutes, despite the stable hemodynamics of the patient. The case was considered a subdural block, and the patient was provided with respiratory support. The subdural block is expected to start slowly (approximately 15-20 minutes), but in this case, after about 10 minutes of receiving anesthesia, the patient suddenly had a loss of consciousness. After the recovery of consciousness and return of spontaneous respiration, the level of a sensory block of the patient, who was cooperative and oriented, was T4. There were motor blocks in both lower extremities. Four hours after intrathecal injection, both the sensory and motor blocks ended, and she was discharged two days later with no complications. Hence, patients who receive spinal anesthesia should be closely observed for any such undesirable complications.

Resumo A perda de consciência durante a raquianestesia é uma complicação rara, mas assustadora. Essa complicação geralmente está relacionada à grave hipotensão e bradicardia, mas, neste caso, a perda de consciência ocorreu em uma paciente parturiente hemodinamicamente estável. Apresentamos o caso de uma paciente de 31 anos, submetida a uma cesariana de emergência. A paciente perdeu a consciência e apresentou apneia que teve início 10 minutos após a raquianestesia bem-sucedida e repetiu o episódio três vezes por 25 minutos, a despeito de sua hemodinâmica estável. O caso foi considerado como um bloqueio subdural e a paciente recebeu suporte respiratório. Espera-se que o bloqueio subdural inicie lentamente (aproximadamente 15-20 minutos), mas, neste caso, cerca de 10 minutos após a anestesia, a paciente repentinamente perdeu a consciência. Após a recuperação da consciência e o retorno da respiração espontânea, a paciente que estava orientada e cooperativa apresentou nível de bloqueio sensorial em T4. Havia bloqueio motor em ambas as extremidades inferiores. O bloqueio sensório-motor terminou quatro horas após a injeção intratecal e a paciente recebeu alta hospitalar dois dias depois, sem complicações. Considerando o exposto, os pacientes que recebem raquianestesia devem ser atentamente observados para quaisquer complicações indesejáveis.

Introducción: Los fibromas uterinos, también conocidos como miomas o leiomiomas son los tumores benignos más frecuentes de la porción superior del aparato genital femenino; pueden alcanzar gran tamaño y generalmente no requieren de tratamiento quirúrgico durante el embarazo. La prevalencia del mioma en el embarazo es desconocida. El manejo quirúrgico se reserva solo para los miomas complicados. Objetivo: Mostrar un caso al que se realizó la miomectomía de un gran fibroma suberoso sintomático coexistente con un embarazo de 21 semanas, debido a que no es frecuente su realización en la práctica médica. Presentación de caso: Paciente de 41 años, nulípara, de 21 semanas de gestación, con síntomas compresivos dados por vómitos, molestias digestivas e intolerancia al decúbito supino, afectada por un gran mioma, que fue sometida a miomectomía. La paciente evolucionó satisfactoriamente. Acudió a consultas prenatales cada 15 días hasta las 39,6 semanas, en que se le realizó la cesárea electiva obteniéndose un recién nacido de buen peso y Apgar. Conclusiones: La miomectomía durante el embarazo es un proceder quirúrgico seguro y eficiente con altas tasas de éxito. La discusión del caso es esencial y debe ser realizada por un equipo multidisciplinario, con experiencia probada en cirugía ginecológica(AU)

Introduction: Uterine fibroids, also known as myomas or leiomyomas are the most frequent benign tumors of the upper portion of the female genital tract. They can reach large size and generally do not require surgical treatment during pregnancy. The prevalence of myoma in pregnancy is unknown. Surgical management is reserved only for complicated myomas. Objective: To report a case in which the myomectomy was performed to a large symptomatic suberose fibroid coexisting with a 21-week pregnancy, which is not frequent in medical practice. Case report: A 41-year-old nulliparous patient, 21 weeks pregnant had compressive symptoms due to vomiting, digestive discomfort and intolerance to the supine position. She underwent myomectomy because she was affected by a large myoma. The patient evolved satisfactorily. She was followed up at prenatal consultations every 15 days until 39.6 weeks, when she had an elective caesarean section, resulting a newborn of good weight and Apgar. Conclusions: Myomectomy during pregnancy is a safe and efficient surgical procedure with high success rates. Case discussion is essential and should be carried out by a multidisciplinary team, with proven experience in gynecological surgery(AU)

Intrauterine device insertion during cesarean section in women without prenatal contraception counseling: lessons from a country with high cesarean rates / Inserção de dispositivo intrauterino durante a cesárea em mulheres sem aconselhamento contraceptivo pré-natal: lições de um país com elevada taxa de cesárea

Abstract Objective Themoment of admission for deliverymay be inappropriate for offering an intrauterine device (IUD) to women without prenatal contraception counseling. However, in countries with high cesarean rates and deficient prenatal contraception counseling, this strategy may reduce unexpected pregnancies and repeated cesarean sections. Methods This was a prospective cohort study involving 100 women without prenatal contraception counseling. Postplacental IUD was offered after admission for delivery and placed during cesarean. The rates of IUD continuation, uterine perforation, and endometritis were assessed at 6 weeks and 6 months, and the proportion of women continuing with IUD at 6 months was assessed with respect to the number of previous cesareans. Results Ninety-seven women completed the follow-up. The rate of IUD continuation was 91% at 6 weeks and 83.5% at 6 months. The expulsion/removal rate in the first 6 weeks was not different from that between 6 weeks and 6 months (9 vs 9.1%, respectively). There were 2 cases of endometritis (2.1%), and no case of uterine perforation. Among 81 women continuing with intrauterine device after 6-months, 31% had undergone only the cesarean section in which the IUD was inserted, 44% had undergone 2 and 25% had undergone 3 or more cesarean sections. Conclusion Two thirds of the women who continued with IUD at 6 months had undergone 2 ormore cesarean sections. Since offering trial of labor is unusual after 2 or more previous cesareans, we believe that offering IUD after admission for delivery may reduce the risk of repeated cesarean sections and its inherent risks.

Resumo Objetivo O momento da admissão para o parto pode ser considerado inapropriado para oferecer o dispositivo intrauterino (DIU) para mulheres sem aconselhamento contraceptivo pré-natal. Entretanto, em países com elevadas taxas de cesáreas e aconselhamento contraceptivo deficiente, essa estratégia pode reduzir o risco de gestações não programadas e cesáreas repetidas. Métodos Estudo de coorte envolvendo 100 mulheres sem aconselhamento contraceptivo pré-natal. A inserção de DIU pós-dequitação foi oferecida após a admissão para o parto e indicação de cesárea. As taxas de continuidade com o DIU, perfuração uterina e endometrite foram avaliadas após 6 semanas e 6 meses, e a proporção de mulheres que continuaram com o DIU após 6 meses foi analisada em relação ao número de cesáreas prévias. Resultados Noventa e sete mulheres completaram o seguimento. A taxa de permanência do DIU foi de 91% em 6 semanas e 83,5% em 6 meses. A taxa de expulsão/ remoção nas primeiras 6 semanas foi não foi diferente daquela observada entre 6 emanas e 6 meses (9 vs 9,1%, respectivamente). Houve dois casos de endometrite (2,1%), e nenhum caso de perfuração uterina. Entre as 81mulheres que permaneceram como DIU após 6 meses, 31% haviam sido submetidas a apenas uma cesárea, em que o DIU foi inserido, 44% a 2, e 25% a 3 ou mais cesáreas. Conclusão Dois terços das mulheres que continuaram com o DIU após 6 meses haviam sido submetidas a 2 ou mais cesáreas. Considerando que oferecer a tentativa de parto vaginal após duas oumais cesáreas prévias é incomum, é possível que a oferta do DIU na admissão para o parto possa reduzir o risco de cesáreas repetidas e de seus riscos associados.

Ultrasound assessment of gastric antrum in term pregnant women before elective cesarean section / Ultrassom de antro gástrico em gestantes a termo antes de cesariana eletiva

Abstract Background and objectives: Pregnant women are considered patients at risk for pulmonary aspiration of gastric contents. The study aim was to evaluate the gastric antral cross-sectional area using ultrasound. Method: In this prospective study, 85 scheduled term pregnant women underwent gastric ultrasound. The outcomes were the measurement of the gastric antral cross-sectional area (main outcome), the estimated gastric volume, the incidence of pregnant women at risk for pulmonary aspiration, and the association between gastric antral cross-sectional area and clinical-demographic characteristics. Gastric antral cross-sectional area and gastric volume were compared according to body mass index <30 or ≥30. Results: The median (IIQ) for gastric antral cross-sectional area was 4 cm2 (2.8-6.3), for the estimated gastric volume it was 49.8 mL (33.7-87.2), and for the gastric volume estimated in mL.kg-1 it was 0.62 mL.kg-1 (0.39-0.95). The 95th percentile [95% confidence interval (CI)] of the gastric antral cross-sectional area and the estimated gastric volume were ≤10.3 cm2 (95% CI: 7.6-15.6) and 1.42 mL.kg-1 (95% CI: 1.20-2.64), respectively. The incidence of pregnant women at risk for pulmonary aspiration was 3.5% (CI: 3.5 (1.2-9.8)). There was a positive correlation between gastric antral cross-sectional area and weight, p < 0.001 and body mass index <0.001. Patients with a body mass index ≥30 had a gastric antral cross-sectional area and an estimated gastric volume greater than those with a body mass index <30, respectively, p < 0.01 and p < 0.02. Conclusion: Measuring the gastric antral cross-sectional area of pregnant women is feasible and easy. There was positive correlation between gastric antral cross-sectional area, body weight and body mass index. The estimation of gastric volume by measuring the gastric antral cross-sectional area can identify patients at risk for pulmonary aspiration. Obese patients had a gastric antral cross-sectional area and an estimated gastric volume greater than non-obese patients.

Resumo Justificativa e objetivos: As gestantes são consideradas pacientes de risco para aspiração pulmonar do conteúdo gástrico. O objetivo foi avaliar a área transversal do antro gástrico por meio de ultrassonografia. Método: Neste estudo prospectivo, 85 gestantes a termo agendadas foram submetidas à ultrassonografia do antro gástrico. Os desfechos foram a mensuração da área transversal do antro gástrico (desfecho principal), a estimativa do volume gástrico, a incidência de gestantes sob risco de aspiração pulmonar, a associação entre a área transversal do antro gástrico e características clínico-demográficas. A área transversal do antro gástrico e do volume gástrico foi comparada de acordo com o índice de massa corporal < 30 ou ≥ 30. Resultados: A mediana (IIQ) da área transversal do antro gástrico foi 4 cm2 (2,8-6,3), do volume gástrico estimado 49,8 mL (33,7-87,2) e do volume gástrico estimado em mL.kg-1 de 0,62 mL.kg-1 (0,39-0,95). O percentil 95 [intervalo de confiança (IC) 95%] da área transversal do antro gástrico e do volume gástrico estimado foi ≤ 10,3 cm2 (IC 95%: 7,6-15,6) e 1,42 mL.kg-1 (IC 95%: 1,20-2,64), respectivamente. A incidência de gestantes sob risco de aspiração pulmonar foi de 3,5% (IC: 3,5 (1,2-9,8). Houve correlação positiva entre a área transversal do antro gástrico e peso, p < 0,001 e índice de massa corporal p < 0,001. As pacientes com índice de massa corporal ≥ 30 apresentaram maior área transversal do antro gástrico, e do volume gástrico estimado, do que as com índice de massa corporal < 30, respectivamente p < 0,01 e p < 0,02. Conclusão: A mensuração da área transversal do antro gástrico de gestantes é factível e fácil. A área transversal do antro gástrico correlacionou-se positivamente com peso e índice de massa corporal. A estimativa do volume gástrico através da mensuração da área transversal do antro gástrico pode identificar pacientes sob risco de aspiração pulmonar. As pacientes obesas apresentaram área transversal do antro gástrico e volume gástrico estimado maior do que as não obesas.

Manejo anestésico para la cesárea en una paciente con síndrome de Klippel-Trenaunay. Reporte de un caso / Anesthetic management for cesarean section in a patient with Klippel-Trenaunay syndrome. Report of a case

Klippel-Trenaunay syndrome is a rare disease that includes the triad of malformation of vascular capillaries, varicose veins and/or venous malformation and hypertrophy of soft or bony tissues. Its presence during pregnancy poses an anesthetic challenge due to the high obstetric risk due to thromboembolic and/or hemorrhagic phenomena. We present the case of a pregnant woman with the diagnosis of Klippel-Trenaunay syndrome announced for elective cesarean section. Our objective is to expose the anesthetic management carried out and to propose a strategic guide for anesthesiologists.

Presentamos el caso de una embarazada con el diagnóstico de síndrome de Klippel-Trenaunay anunciada para cesárea electiva. Nuestro objetivo es exponer el manejo anestésico realizado y proponer una guía estratégica para los anestesiólogo

Intérêt de l'association bupivacaïne-fentanyl-morphine intrathécale pour l'analgésie post-césarienne au centre hospitalier universitaire de Libreville

Introduction. La césarienne est un acte chirurgical le plus souvent réalisé sous rachianesthésie. Le but de ce travail était d'évaluer la qualité de l'analgésie chez des parturientes ayant bénéficié d'une césarienne pratiquée sous rachianesthésie associant bupivacaïne, fentanyl et morphine. Patientes et méthodes. Il s'agit d'une étude prospective, descriptive, d'une durée de deux ans (1er mai 2016 au 30 avril 2018). Les critères d'inclusion étaient: être opérée pour césarienne en chirurgie programmée ou en urgence relative, être sous rachianesthésie réalisée avec l'association bupivacaïne, fentanyl et morphine. Les variables étudiées étaient les données sociodémographiques, les paramètres hémodynamiques et respiratoires, l'apparition de la douleur, la durée des blocs sensitif et moteur, les effets indésirables et la satisfaction de la patiente. Résultats. 1645 césariennes ont été pratiquées soit 18,5% des naissances. 250 patientes ont été retenues, 160 (64%) en urgence relative et 90 (36%) en chirurgie programmée. L'âge moyen des patientes était de 27,5 ± 6,1 ans. L'extension des blocs était au niveau de T6 dans 64% des cas. Les besoins en analgésiques intraveineux étaient observés à H4, H8 et H12 pour 15 patientes (6%), 25 patientes (10%) et 80 (32%) respectivement. Les effets secondaires les plus rencontrés étaient les nausées-vomissements (12%) et le prurit (18%). Le taux de satisfaction des parturientes concernant les informations sur la technique et le protocole anesthésique était de 92%. Conclusion. Le protocole bupivacaïne-fentanyl-morphine en intrathécal procure une analgésie efficace et durable. Il devrait s'intégrer dans notre stratégie d'analgésie multimodale postopératoire
