INTRODUCTION: Perinatal asphyxia is one of the most frequent causes of neonatal mortality, affecting approximately four million newborns worldwide each year and causing the death of one million individuals. One of the main reasons for these high incidences is the lack of consensual methods of early diagnosis for this pathology. Estimating risk-appropriate health care for mother and baby is essential for increasing the quality of the health care system. Thus, it is necessary to investigate models that improve the prediction of perinatal asphyxia...

INTRODUCTION: Despite the advancements in perinatal care in past decades, perinatal asphyxia remains a serious problem leading to significant perinatal morbidity and mortality. Therefore, foetal monitoring during the intrapartum period is of paramount importance. Among various methods of fetal monitoring, cardiotocography is a form of electronic foetal monitoring in which there is simultaneous recording of foetal heart rate and uterine contractions. MATERIALS AND METHODS: This cross-sectional observational study was done in the labour room and neonatal intensive care unit (NICU) of a teaching Municipal Hospital in North India including 500 pregnant women of age group 18-45 years with singeleton fetus of gestation ≥36 weeks without any known congenital anomaly...

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...

To date, cardiotocography (CTG) is the only non-invasive and cost-effective tool available for continuous monitoring of the fetal health. In spite of a marked growth in the automation of the CTG analysis, it still remains a challenging signal processing task. Complex and dynamic patterns of fetal heart are poorly interpreted. Particularly, the precise interpretation of the suspected cases is fairly low by both visual and automated methods. Also, the first and second stage of labor produce very different fetal heart rate (FHR) dynamics...

OBJECTIVE: To establish the correlation of phase-rectified signal averaging (PRSA) outputs between a novel self-applicable non-invasive fetal electrocardiography (NIFECG) monitor, and the computerized cardiotocograph (cCTG). A secondary objective is to evaluate the potential for assessing fetal wellbeing in the remote setting by assessing the relationship PRSA to short-term variation (STV). METHODS: This was a prospective observational study carried out in a London teaching hospital...

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...

Thrombotic thrombocytopenic purpura (TTP) is a rare and life-threatening disease for which pregnancy and the postpartum period represent risk factors. Here, we present the case of a 39-year-old woman at the 31st week of gestation, who presented with cutaneous haemorrhagic symptoms. The complete blood count showed anaemia, thrombocytopenia, increase in haemolysis indices and undetectable ADAMTS13 activity. Acquired TTP was diagnosed, and she started daily plasma exchange (PEX) and methylprednisolone. After 5 days, an emergency caesarean section was performed with success because of pathologic cardiotocographic findings...

An essential role played by cardiotocography (CTG), is promptly detecting non-reassuring foetal status during delivery, as these abnormal changes are a prime reason for women to undergo a caesarean section. But all abnormal changes in cardiotocography does not lead to poor outcome in terms of liquor that was meconium stained or a low APGAR score at birth. As a result, research is the need of the hour, to understand their correlation; hence, showing the benefit of CTG in the precise detection of non-reassuring foetal status is correlated from the intraoperative findings discovered later...

BACKGROUND AND OBJECTIVE: Prenatal fetal monitoring, which can monitor the growth and health of the fetus, is very vital for pregnant women before delivery. During pregnancy, it is crucial to judge whether the fetus is abnormal, which helps obstetricians carry out early intervention to avoid fetal hypoxia and even death. At present, clinical fetal monitoring widely used fetal heart rate monitoring equipment. Fetal heart rate and uterine contraction signals obtained by fetal heart monitoring equipment are important information to evaluate fetal health status...

PURPOSE: To determine the association between the occurrence of sporadic and periodic fetal heart rate accelerations during labor and acidemia at birth. MATERIALS AND METHODS: This is a case-control study of fetal heart rate patterns from 364 neonates with acidemia at birth (cord blood pH <7.05 at vaginal birth, or pH <7.10 at birth after first stage cesarean delivery) and 731 controls with pH ≥7.15. The last 30-60 min of the cardiotocographic traces before birth from the neonates born with acidemia and from the corresponding stage in labor for the controls were scrutinized...

OBJECTIVES: Fully effective intrapartum cardiotocographic (CTG) fetal heart monitoring is still missing. Visual analysis is far from credibility. Additional, computerized analysis techniques were proposed however they did not substantially decrease possible risks of fetal asphyxia. In twin pregnancies the problem is even more complicated. Our goal is to find the most valuable parameters in intrapartum CTG surveillance in twins, based on actual FIGO criteria. MATERIAL AND METHODS: Study included 58 women in labor who had been admitted to Delivery Department of tertiary care hospital with twin pregnancy in a period of one year...

BACKGROUND: Cerebral palsy is more common among preterm infants than among full-term infants. Although there is still no clear evidence that fetal heart rate monitoring effectively reduces cerebral palsy incidence, it is helpful to estimate the timing of brain injury leading to cerebral palsy and the causal relationship with delivery based on the fetal heart rate evolution patterns. Understanding the relationship between the timing and the type of brain injury can help to identify preventive measures in obstetrical care...

Fetal Cardiography is usually performed using in-hospital Cardiotocographic (CTG) devices to assess fetal wellbeing. New technologies may permit home-based, self-administered examinations. We compared the accuracy, clinical interpretability, and user experience of a patient-administered, wireless, fetal heartbeat monitor (HBM) designed for home use, to CTG. Initially, participants had paired HBM and CTG examinations performed in the clinic. Women then used the HBM unsupervised and rated the experience. Sixty-three women had paired clinic-based HBM and CTG recordings, providing 6982 fetal heart rate measures for point-to-point comparison from 126 min of continuous recording...

Morbid obesity and prolonged pregnancy are independently associated with adverse delivery and perinatal outcomes. We conducted a retrospective observational study on otherwise uncomplicated women with a body mass index (BMI) ≥ 40 kg/m2 where, having reached term, induction of labour (IOL) was planned, to prevent prolonged pregnancy. The primary aim was to describe delivery outcomes and short-term maternal and perinatal adverse events. Of 117 cases included, 69 (59%) laboured spontaneously before the induction date, while 48 (41%) required an IOL...

BACKGROUND: International guidelines recommend intrapartum cardiotocograph (CTG) monitoring for women at risk for poor perinatal outcome. Research has not previously addressed how midwives and obstetricians enable or hinder women's decision-making regarding intrapartum fetal monitoring and how this work is structured by external organising factors. AIM: To examine impacts of policy and research texts on midwives' and obstetricians' work with labouring women related to intrapartum fetal monitoring decision-making...

CONTEXT: The computerization of both fetal heart rate (FHR) and intelligent classification modeling of the cardiotocograph (CTG) is one of the approaches that are utilized in assisting obstetricians in conducting initial interpretation based on (CTG) analysis. CTG tracing interpretation is crucial for the monitoring of the fetal status during weeks into the pregnancy and childbirth. Most contemporary studies rely on computer-assisted fetal heart rate (FHR) feature extraction and CTG categorization to determine the best precise diagnosis for tracking fetal health during pregnancy...

Prenatal fetal monitoring, which can monitor the growth and health of the fetus, is vital for pregnant women before delivery. During pregnancy, it is essential to classify whether the fetus is abnormal, which helps physicians carry out early intervention to avoid fetal heart hypoxia and even death. Fetal heart rate and uterine contraction signals obtained by fetal heart monitoring equipment are essential to estimate fetal health status. In this paper, we pre-process the obtained data set and enhance them using Hermite interpolation on the abnormal classification in the samples...

In this work we present the creation of a large, structured database of CardioTocoGraphic (CTG) recordings, starting from a raw dataset containing tracings collected between 2013 and 2021 by the medical team of the University Hospital Federico II of Naples. The aim of the work is to provide a big, structured database of real clinical cardiotocographic data, useful for subsequent processing and analysis through state-of-the-art methods, in particular Deep Learning Methods. This organized dataset could lead to an increase of the diagnostic accuracy of CTG analysis in the discrimination of healthy and unhealthy fetuses...

INTRODUCTION: Transabdominal electrocardiographic (TAfECG) acquisition of fetal heart rate (FHR) signals has recently been introduced into leading commercial cardiotocographic (CTG) monitors. Continuous wireless transmission of signals has raised the possibility of the technology being used during maternal mobilization in labor. This study aims to evaluate signal quality and accuracy of TAfECG acquisition of FHR signals during static and active maternal positions in labor when compared with Doppler signals and with the gold-standard method of fetal scalp electrode (FSE)...

We present two patients with right lower quadrant pain during the 36th week of pregnancy. In both cases, the challenges in diagnosing acute appendicitis in late pregnancy is underlined by misleading imaging results, revealing fluid in the lower abdomen, suggesting an appendicitis. Surgery was performed. Pre- and intraoperative gynecological examinations showed no signs of fetal distress. In patient 1, surgery revealed a torsion and necrosis of the right ovary and a 7-cm cyst of the fallopian tube. Open ovariectomy and appendectomy were performed...
