Filter by:The main aim of the study is to compare the clinical performance of two adjunctive methods to CTG in intrapartum fetal monitoring: FBS with measurement of scalp lactate and ST analysis of the fetal ECG.
Cardiotocography (CTG) is widely used during labour wards in industrialised countries and consists of fetal heart rate and uterine contraction monitoring. The main aim is to identify fetuses that are being poorly oxygenated during labour and require medical intervention to revert the situation or expedite delivery. The need for technical development of CTG is well-recognized, as some of the existing techniques are prone to signal loss and contamination from the maternal heart rate, while others are invasive and have established contra-indications. They also limit maternal mobilisation, contributing to maternal dissatisfaction, and possibly to adverse maternal and neonatal outcomes. New techniques for CTG acquisition will shortly be made available by a leading technological company, providing non-invasive monitoring and allowing full maternal mobilisation, and with the potential to change the way labour is conducted in high-resource countries. There is a need for a systematic evaluation of their clinical performance and benefit.
Despite its limitations, fetal heart rate (FHR) tracing analysis is the best monitor of fetal well-being during labor or preparation for cesarean delivery. Current monitoring methods: transabdominal ultrasound (CTG: cardiotocograph) and fetal scalp electrodes (FSE) have limitations (tracing loss during fetal movement, potential to confuse maternal for fetal heart rate, inability to monitor during cesarean section or abdominal surgery) and, in the latter case, risks (infection, hematoma). A reliable, non-invasive monitor of the fetal heart rate that can be used during labor, non-obstetric and obstetric surgery during pregnancy is needed. Recent developments in use of maternal abdominal electrodes for extraction of the FHR and contraction information inform this study. LaborView®, developed by researchers at University of Florida (UF) College of Medicine and OBMedical, is an FDA-approved non-invasive labor monitoring device. Refinement of the extraction algorithms continues, and that work is most effectively performed at UF, where the primary researchers and OBMedical are located. LaborView monitoring will be recorded from up to150 subjects admitted to Labor and Delivery at UFHealth. Data will be simultaneously obtained from the standard labor monitor. These signals will then be analyzed off-line for comparison and refinement of algorithms.
This is a feasibility study for a new application for capturing fetal cardiac activity. The objective of this study is to determine if it is feasible to capture a fetal ECG signal using a Holter ECG device. As comparison we will use a standard Doppler Fetal Heart Rate (FHR) device.
Fetal heart rate [FHR] monitoring is used widely to assess the well-being of the baby in the delivery period. If it is determined that an urgent cesarean delivery is required because of fetal distress, FHR is discontinued once the mother is in the operating room in order to allow for surgical site preparation. From this point, there is no real-time monitoring that permits assessment of the well-being of the infant. The investigators are evaluating the feasibility of intraoperative FHR monitoring using fetal ECG placed on the mother's upper abdominal wall and the standard acoustic device routinely used. The investigators will compare these to the traditional well-being tests: umbilical arterial blood gas and Apgar score. The first 15 subjects will be recruited from pregnant women who have scheduled induction of labor. The subsequent 40 subjects will be recruited from pregnant women who have scheduled cesarean sections.
Annually, an estimated 2.6 million still births occur half of which die during labor and delivery (fresh stillbirths). In addition, around 750,000 newborns die shortly after birth due to intrapartum-related hypoxia or birth asphyxia. Almost 99% of these perinatal deaths take place in low-income countries where the provider/patient ratio is low and fetal monitoring is inadequate. Poor intrapartum fetal heart rate monitoring, failure to identify fetal distress, and subsequently intervene, is a common pathway to perinatal deaths in these low-resourced settings. Recently, an innovative fetal heart rate monitoring device, called Moyo, using ultrasound technology, was developed to be strapped on the mother during labour. This project will compare the effectiveness of automatic use of Moyo versus intermittent use of hand-held fetoscope in detection of abnormal fetal heart rate, through a randomized control study, at Haydom Hospital, Tanzania.
