OBJECTIVE To assess the cost-effectiveness of the use of cardiotocography (CTG) complemented with fetal electrocardiography and ST analysis compared with the use of CTG alone in term deliveries when a decision has been made to use fetal monitoring with a scalp electrode. DESIGN A cost-effectiveness analysis based on a probabilistic decision model incorporating relevant strategies and lifelong...

CONTEXT Numerous randomized controlled trials have demonstrated limited efficacy of intrapartum fetal heart rate monitoring in improving fetal outcome. A potential reason is the wide variability in clinical decision making seen with its use. Standardizing management of variant intrapartum fetal heart rate tracings may reduce this variability and lead to improvement in fetal outcome. OBJECTIVE...

BACKGROUND The currently used fetal monitoring instrumentation that is based on Doppler ultrasound technique provides the fetal heart rate (FHR) signal with limited accuracy. It is particularly noticeable as significant decrease of clinically important feature - the variability of FHR signal. The aim of our work was to develop a novel efficient technique for processing of the ultrasound signal,...

OBJECTIVES This paper describes a methodology for the monitoring of the fetal cardiac health status during pregnancy, through the effective and non-invasive monitoring of the abdominal ECG signals (abdECG) of the mother. METHODS For this purpose, a three-stage methodology has been developed. In the first stage, the fetal heart rate (fHR) is extracted from the abdECG signals, using nonlinear a...

BACKGROUND Women's views are critical for informing the planning and delivery of maternity care services. ST segment analysis (STan) is a promising method to more accurately detect when unborn babies are at risk of brain damage or death during labour that is being trialled for the first time in Australia. This is the first study to examine women's views about STan monitoring in this context. ...

Treatment and outcome of childbirth depend on the acidobasic balance of the fetal blood related to the oxygen and carbon dioxide level. Hypoxemia could lead to asphyxia that is why fetal monitoring and biochemical parameters assessment are mandatory. Although there are compensatory mechanisms that temporarily protect the fetus, there are also other factors that interfere with the oxygenation of...

The fetal heart beat, detected by ultrasound, was recorded for five minutes from 934 antenatal women--266 at 30 to 35 weeks' gestation and 718 at 36 to 41 weeks. Episodes of bradycardia < 100/minute ranging from 5-30 seconds' duration occurred in 3 (1.1%) of the former and in 9 (1.3%) of the latter group. Tachycardia > 180/minute ranging from 30-90 seconds' duration occurred in 1 (0.4%) of the ...

Trauma is currently the most common non-obstetric cause of morbidity and mortality during pregnancy. It is estimated that 6-7% of all pregnancies are complicated by significant trauma. This presents a unique situation for the emergency physician. Changes occur throughout pregnancy that can alter the presentation and treatment of injury. Additionally, there are potentially two lives at stake. Wh...
