antepartum fetal heart rate

PURPOSE OF REVIEW: Hypertensive disorders of pregnancy (HDP) pose a significant threat to maternal cardiovascular health, with emerging research shedding light on the enduring risks beyond the gestational period. This review highlights updates regarding cardiovascular risks associated with HDP and their implications for long-term health. RECENT FINDINGS: Patients with a history of HDP are at an elevated risk of developing chronic hypertension, ischemic heart disease, stroke, valvular heart disease, and heart failure...

OBJECTIVE: To evaluate efficacy in achieving vaginal delivery with a standardized vaginal compared with oral misoprostol regimen for labor induction at term. METHODS: In this single-center, cluster randomized trial, we randomized induction method by week among individuals with gestational age of 37 weeks or more, cervical dilation of 2 cm or less, intact membranes, and indication for delivery to either oral (100 micrograms every 4 hours for up to two doses), or vaginal (25 micrograms every 3 hours for up to five doses) misoprostol regimens, followed by a standardized oxytocin protocol...

Basal ganglia and thalamus (BGT) hypoxic-ischaemic brain injury is currently the most contentious issue in cerebral palsy (CP) litigation in South Africa (SA), and merits a consensus response based on the current available international literature. BGT pattern injury is strongly associated with a preceding perinatal sentinel event (PSE), which has a sudden onset and is typically unforeseen and unpreventable. Antepartum pathologies may result in fetal priming, leading to vulnerability to BGT injury by relatively mild hypoxic insults...

INTRODUCTION: Cardiovascular disease is the leading cause of pregnancy-related mortality, and it has gradually increased over time; this rise has been attributed to numerous reasons including the growing number of women with congenital heart disease who are surviving to childbearing age. Valve surgery during pregnancy is a high risk, with a fetal and maternal mortality rate of 35% and 9%, respectively. Prior knowledge about the cardiovascular disease opens up a host of options for the mother even during pregnancy, but presentation in the 3rd trimester puts both the mother and the baby at risk...

BACKGROUND: Meconium stained amniotic fluid (MSAF) is a commonly observed phenomenon in day-to-day practice of obstetrics. The reported prevalence of MSAF was 7-22% of all term deliveries. Some of the factors that increases the risk of meconium stained amniotic fluid includes; advanced gestational age at delivery, prolonged rupture of membranes, intra-amniotic infection, pre-eclampsia, oligohydroamnios, and diabetes mellitus. The study aimed to determine the prevalence of meconium stained amniotic fluid and its associated factors among women who gave birth at term, from January 1st to July 30th , 2020, at Adama Hospital Medical College...

PURPOSE: Cardiotocography (CTG), which measures uterine contraction (UC) and fetal heart rate (FHR), is a crucial tool for assessing fetal health during pregnancy. However, traditional computerized cardiotocography (cCTG) approaches have non-negligible calibration errors in feature extraction and heavily rely on the expertise and prior experience to define diagnostic features from CTG or FHR signals. Although previous works have studied deep learning methods for extracting CTG or FHR features, these methods still neglect the clinical information of pregnant women...

Cardiotocography (CTG) is one of the fundamental prenatal diagnostic methods for both antepartum and intrapartum fetal surveillance. Although it has allowed a significant reduction in intrapartum and neonatal mortality and morbidity, its diagnostic accuracy is, however, still far from being fully satisfactory. In particular, the identification of uncertain and suspicious CTG traces remains a challenging task for gynecologists. The introduction of computerized analysis systems has enabled more objective evaluations, possibly leading to more accurate diagnoses...

AIM: This retrospective study was performed to investigate whether certain fetal heart rate patterns were associated with subsequent cerebral palsy (CP) in infants with chorioamnionitis at or near term. METHODS: We used cases registered by the Japan Obstetric Compensation System for CP, which is a nationwide population-based database. Among them, 133 infants with chorioamnionitis who were born at ≥34 weeks of gestation were enrolled. All infants underwent magnetic resonance imaging (MRI), and all fetal heart rate charts had been interpreted according to the National Institute of Child Health and Human Development criteria, focusing on antepartum and immediately before delivery...

BACKGROUND: Pregnancies after solid organ transplant are at a higher risk of antepartum admission and pregnancy complications including cesarean delivery. Emergent prelabor cesarean delivery is associated with increased maternal and neonatal morbidity in other high-risk populations, but its incidence and impact in transplant recipients is not well-understood. OBJECTIVE: This study aimed to characterize the risk factors and outcomes of emergency prelabor cesarean delivery in kidney and liver transplant recipients...

We have developed deep learning models for automatic identification of the maternal heart rate (MHR) and, more generally, false signals (FSs) on fetal heart rate (FHR) recordings. The models can be used to preprocess FHR data prior to automated analysis or as a clinical alert system to assist the practitioner. Three models were developed and used to detect (i) FSs on the MHR channel (the FSMHR model), (ii) the MHR and FSs on the Doppler FHR sensor (the FSDop model), and (iii) FSs on the scalp ECG channel (the FSScalp model)...

OBJECTIVES: The objective of this study is to present the why, what and how about computerized analysis of cardiotocograms (cCTG) and the SisPorto system for cCTG. CONTENT: A narrative review about cCTG and the SisPorto system for cCTG is presented. The meta-analysis of randomized controlled trials (RCT) performed so far have evidenced that cCGT compared to traditional CTG analysis may save time spent in hospital for women, in the antepartum period, and is objective with at least equivalent results in maternal and perinatal outcomes, both in the ante and intrapartum periods...

BACKGROUND: Apgar score is used to evaluate the neonates' overall status and response to resuscitation, as well as its prognosis beyond the neonatal period. Low fifth minute Apgar scores is more frequent and is associated with markedly increased risks of neonatal mortality and morbidity. In Ethiopia, the prevalence of birth asphyxia is high (22.52%). Birth asphyxia contributes to significant neonatal morbidities and mortalities due to severe hypoxic-ischemic multi-organ damage, mainly brain damage...

BACKGROUND: In low-resource settings, patient referral to a hospital is an essential part of the primary health care system. However, there is a paucity of study to explore the challenges and quality of referral coordination and communication. OBJECTIVE: The purpose of this research was to analyze the existing paper-based referral registration logbook for maternal and child health in general and women of reproductive age in particular, to improve referral coordination and evidence-based services in Low-Resource Settings...

Background: Uterine activity (UA) monitoring is an essential element of pregnancy management. The gold-standard intrauterine pressure catheter (IUPC) is invasive and requires ruptured membranes, while the standard-of-care, external tocodynamometry (TOCO)'s accuracy is hampered by obesity, maternal movements, and belt positioning. There is an urgent need to develop telehealth tools enabling patients to remotely access care. Here, we describe and demonstrate a novel algorithm enabling remote, non-invasive detection and monitoring of UA by analyzing the modulation of the maternal electrocardiographic and phonocardiographic signals...

BACKGROUND: Fetal heart block (FHB) occurs in approximately 1:20 000 births and is associated with significant morbidity and mortality. Vaginal delivery with intrapartum fetal scalp lactate monitoring is offered as an option at our centre for selected cases, in contrast with the published literature advocating caesarean birth. AIMS: To review perinatal outcomes at delivery for FHB at a tertiary referral hospital. MATERIALS AND METHODS: Ours was a retrospective cohort study from 1 January, 2007 to 30 June, 2020...

PURPOSE: Fetal well-being is usually assessed via fetal heart rate (FHR) monitoring during the antepartum period. However, the interpretation of FHR is a complex and subjective process with low reliability. This study developed a machine learning model that can classify fetal cardiotocography results as normal or abnormal. MATERIALS AND METHODS: In total, 17492 fetal cardiotocography results were obtained from Ajou University Hospital and 100 fetal cardiotocography results from Czech Technical University and University Hospital in Brno...

To investigate whether earlier "post-term" monitoring of South Asian (SA) pregnancies from 39 weeks' gestation with amniotic fluid index (AFI) and cardiotocography (CTG) detected suspected fetal compromise. Retrospective cohort study of all SA-born women at an Australian health service with uncomplicated, singleton pregnancies following the introduction of twice-weekly AFI and CTG monitoring from 39 weeks. Monitoring results, and their association with a perinatal compromise composite (including assisted delivery for fetal compromise, stillbirth, and NICU admission) were determined...

BACKGROUND: Worldwide, hypertensive disorders of pregnancy (HDP), fetal growth restriction (FGR) and preterm birth remain the leading causes of maternal and fetal pregnancy-related mortality and (long-term) morbidity. Fetal cardiac deformation changes can be the first sign of placental dysfunction, which is associated with HDP, FGR and preterm birth. In addition, preterm birth is likely associated with changes in electrical activity across the uterine muscle. Therefore, fetal cardiac function and uterine activity can be used for the early detection of these complications in pregnancy...

Background Determination of Amniotic Fluid Index (AFI) is an important component of antepartum assessment of all normal pregnancies. Objective To compare the obstetric interventions and neonatal outcomes in term pregnancies with borderline Amniotic Fluid Index versus normal Amniotic Fluid Index. Method This hospital based prospective study was conducted at Tribhuwan University Teaching Hospital over 1 year between 2017 and 2018 in 128 women having uncomplicated term pregnancy admitted in labor ward. Of the 128 women, 64 women had borderline Amniotic Fluid Index (5...

BACKGROUND: The clinical diagnosis of late Fetal Growth Restriction (FGR) involves the integration of Doppler ultrasound data and Fetal Heart Rate (FHR) monitoring through computer assisted computerized cardiotocography (cCTG). The aim of the study was to evaluate the diagnostic power of combined Doppler and cCTG parameters by contrasting late FGR -and healthy controls. METHODS: The study was conducted from January 2018 to May 2020. Only pregnant women who had the last Doppler measurement obtained within 1 week before delivery and cCTG performed within 24 h before delivery were included in the study...
