Obstetric; hemodynamic

Preeclampsia remains the leading cause of maternal morbidity and mortality and is associated with abnormal body fluid homeostasis and cardiovascular dysfunction. Moreover, 2 distinct hemodynamic phenotypes have been described in preeclampsia, which might require different therapeutic approaches. Fluid restriction is mandatory in women at risk of pulmonary edema, whereas additional fluid administration may be required to correct tissue hypoperfusion in women with intravascular volume depletion. As clinical examination alone cannot discriminate among different hemodynamic patterns, optimal management of women with preeclampsia remains challenging...

PURPOSE: To investigate the effect of intravenous MgSO4 on maternal cerebral hemodynamics as well as the association between altered Doppler indices of the ophthalmic arteries and ocular lesions in patients with preeclampsia. METHODS: After each of the 15 included patients was diagnosed with preeclampsia, MgSO4 was infused followed by transcranial Doppler tests of the indices of the ophthalmic, anterior, middle, posterior cerebral, vertebral, and basilar arteries, followed by a second MgSO4 infusion...

The prevalence of cardiac disease-related maternal morbidity and mortality is on the rise in the United States. To ensure safe management of pregnancy in patients with cardiovascular disease, pre-delivery evaluation by a multidisciplinary Pregnancy Heart Team should occur. Appropriate anesthetic, cardiac, and obstetric care are essential. Risk stratification tools evaluate the etiology and severity of cardiovascular disease to determine the appropriate hospital type and location for delivery and anesthetic management...

INTRODUCTION: Obesity is known to be associated with cardiovascular compromise and a major risk factor for the development of hypertensive disorders in pregnancy. However, little is known about the effect of obesity on maternal cardiac function. The aim of this study was to investigate the effect of obesity on the maternal cardiovascular system. MATERIAL AND METHODS: This was a prospective, observational, longitudinal study. Pregnant women with booking body mass index (BMI) ≥30 kg/m2 were compared with pregnant women with normal booking BMI 20-24...

BACKGROUND: Present evidence suggests that the Doppler ultrasonographic indices, such as carotid artery blood flow (CABF) and velocity time integral (VTI), had the ability to predict fluid responsiveness in non-obstetric patients. The purpose of this study was to assess their capacity to predict fluid responsiveness in spontaneous breathing parturients undergoing caesarean section and to determine the effect of detecting and management of hypovolemia (fluid responsiveness) on the incidence of hypotension after anaesthesia...

A 32-year-old woman with a large cardiac hamartoma was referred to our institution's cardio-obstetrics group for preconception counseling. Results of hemodynamic testing revealed restrictive physiology. This case highlights the role of multimodality testing in predicting the hemodynamic consequences of pregnancy in the setting of high-risk cardiovascular conditions.

INTRODUCTION: Postpartum hemorrhage (PPH) remains a global health problem. The introduction of resuscitative endovascular balloon occlusion of the aorta (REBOA) in 2008 sought to enhance the management of hemorrhagic shock during PPH. In this study, we present a single Norwegian center's experience with REBOA as a supportive treatment in combating life threatening PPH. MATERIAL AND METHODS: This is a historical cohort study from St Olav's University Hospital, with data from period 2008-2021...

Congenital adrenal hyperplasia (CAH) is a type of primary adrenal insufficiency (AI) that predisposes to adrenal crisis (AC) during stress. We describe a case of a primipara with CAH who was admitted in labor. To prevent AC, glucocorticoid replacement was given according to guidelines. Due to fetal decelerations, an emergency C-section was performed under general anesthesia following which refractory hypotension emerged. The diagnosis of AC was considered, and hydrocortisone was given with sustained hemodynamic improvement...

BACKGROUND: Early recognition of haemodynamic instability after birth and prompt interventions are necessary to reduce adverse maternal outcomes due to postpartum haemorrhage. Obstetric shock Index (OSI) has been recommended as a simple, accurate, reliable, and low-cost early diagnostic measure that identifies hemodynamically unstable women. OBJECTIVES: We determined the prevalence of abnormal obstetric shock index and associated factors among women in the immediate postpartum period following vaginal delivery at Mbarara Regional Referral Hospital (MRRH) in southwestern Uganda...

Tetralogy of Fallot (TOF) is a congenital heart defect characterized by four interlinked cardiac anomalies, leading to cyanosis and significant health risks if left untreated. We present the management and outcome of an adult patient with unrepaired TOF at 34 weeks of pregnancy at a central Johannesburg hospital. Uncorrected TOF in adulthood, especially in the late stages of pregnancy, is rare, presenting challenges for both the mother and baby. This case report outlines our successful management strategy, highlighting the importance of careful hemodynamic stability...

BACKGROUND: Maternal cardiovascular adaptations are amplified in twin pregnancies to support the metabolic request of the feto-placental unit. Few studies have evaluated the maternal hemodynamics changes after routine use of laser surgery in the treatment of twin-twin transfusion syndrome (TTTS). OBJECTIVES: The aim of our study was to evaluate hemodynamic changes in monochorionic twin pregnancies complicated by TTTS before and after treatment with fetoscopic laser surgery...

Hemodynamic changes during pregnancy are physiological adaptations to fulfill new demands. Although these adaptations are often well-tolerated, they may unmask or exacerbate underlying cardiovascular conditions, posing unique challenges for medical professionals. We present a case that outlines the evaluation and treatment of a 38-year-old woman who experienced health complications shortly after undergoing a Caesarean section.  A 38-year-old woman who had a previous caeserean section presented for an urgent caeserean section at 39 weeks of gestational age due to non-reassuring cardiotocography...

Supraventricular tachycardia (SVT) is the most common tachyarrhythmia of pregnancy. Catecholamine surges, the use of vasoactive agents during delivery, and increased cardiac output during pregnancy are the most common contributing factors to developing SVT. SVT is usually benign in presentation but can lead to more serious arrhythmias in patients with a history of mitral stenosis secondary to rheumatic heart disease. When an SVT is detected, organic heart causes should be ruled out first. Symptoms of SVT include shortness of breath, palpitations, syncope, sweating, chest pain, and dizziness...

BACKGROUND: Isolated agenesis of ductus venosus (ADV) is usually a benign condition, but it may be associated with cardiovascular defects, hydrops, growth restriction, and chromosomal abnormalities. Additionally, persistent left superior vena cava (PLSVC) and bovine aortic arch are relatively common fetal anomalies. To the author's knowledge, this is the first report of prenatal detection of DV agenesis and PLSVC associated with the postnatal bovine aortic arch with a hypoplastic transverse aortic arch...

OBJECTIVE: To examine the postnatal course of the ophthalmic artery (OA) Doppler in women with hypertensive disorders of pregnancy (HDP) and evaluate the correlation between OA Dopplers and poor postnatal blood pressure control and renal dysfunction at 2-3 and 6-9 weeks postnatally. METHODS: Prospective cohort study of women with singleton pregnancies with HDP in a tertiary Pregnancy Hypertension clinic. Three visits were included: 1) the last antenatal hypertension clinic visit within 2 weeks prior to delivery, 2) 2-3 weeks postnatally, 3) 6-9 weeks postnatally...

AIMS: The study aims to evaluate the genetic and clinical outcomes of fetal cardiac rhabdomyoma in our tertiary center. METHODS: Data of cases with cardiac rhabdomyoma detected by fetal echocardiography during antenatal follow-up were analyzed retrospectively. RESULTS: Nine cases were included in the study. The incidence of cardiac rhabdomyoma was 0.003%. The median fetal diagnosis time was 26th weeks, the most common location was the LV. There was no hemodynamic disorder requiring cardiovascular intervention in any of the cases...

OBJECTIVE: Reducing maternal morbidity and mortality has been a challenge for low and middle-income countries, especially in the setting of hypertensive disorders of pregnancy. Improved strategies for treating obstetric patients with resistant hypertension are needed. We sought to explore whether hemodynamic parameters may be used to identify patients that develop resistant hypertension in pregnancy. METHODS: Retrospective cohort study among pregnant patients with gestational hypertension or preeclampsia that experienced severe blood pressure elevations...

OBJECTIVE: Initially, medical treatment options are preferred in patients with abnormal uterine bleeding (AUB) who are hemodynamically stable. The aim of the present study was to investigate the effectiveness of a levonorgestrel-releasing intrauterine device (LNG-IUD) in reducing bleeding symptoms in patients with AUB stratified by underlying pathology. MATERIAL AND METHODS: In line with the polyp, adenomyosis, leiomyoma, malignancy (and hyperplasia), coagulopathy, ovulatory disorders, endometrial, iatrogenic and not otherwise classified classification system, patients who were administered LNG-IUD due to adenomyosis, endometrial hyperplasia, leiomyoma and AUB due to not otherwise classified causes were included in the study...

BACKGROUND: Unstable cerebral hemodynamics is an important cause of intracranial hemorrhage in premature infants. The increased blood flow of delayed cord clamping (DCC) compared to immediate cord clamping (ICC) is equivalent to 1/3-1/4 of newborn blood volume. Our objective was to assess whether the increased blood flow causes fluctuations in cerebral blood flow and how. METHODS: This experiment was a prospective, observational study. Neonatologists selected preterm infants eligible for inclusion and exclusion, and divided them into DCC group and ICC group according to the way of umbilical cord ligation performed by obstetrics department, and matched them 1:1 according to gestational age...

BACKGROUND: Induction of labor with extra-amniotic balloon (EAB) catheter is a procedure commonly associated with maternal discomfort, pain, and anxiety. OBJECTIVE(S): We aimed to investigate the distractive effect of virtual reality (VR) technology on pain and anxiety- in pregnant patients who undergo Induction of labor with EAB. STUDY DESIGN: In this randomized controlled trial, pregnant patients intended for Induction of labor with EAB at term, for various obstetric indications, were recruited and randomized in a 1:1 ratio into two groups...
