An assessment of neonatal outcome may be obtained from analysis of blood in the umbilical cord of the infant immediately after delivery. This can provide information on the health of the newborn infant, guide requirements for neonatal care, and is recommended practice of the Royal College of Obstetricians and Gynaecologists. However, there are problems with(More)
OBJECTIVES To address the practical problems of routine umbilical cord blood sampling, to determine the ranges for pH, PCO2 and base deficit and to examine the relationships of these parameters between cord vessels. DESIGN An observational study of umbilical cord artery and vein blood gas results. SETTING A large district general hospital in the UK. (More)
AIMS it is now recommended that cord blood acid-base measurement is performed routinely at time of delivery in the UK as a measure of fetal response to labour. However, there remains some uncertainty about the value of this procedure. In this paper our experience of cord blood analysis is described and the literature is reviewed to: (1) provide an overview(More)
It is possible to record the fetal electrocardiographic waveform (ECG) from the scalp electrode used in labour for detection of fetal heart rate. Animal and observational studies of changes in the ST waveform of the ECG during hypoxia suggest that a combination of heart rate and ST waveform analysis might improve the predictive value of intrapartum(More)
Fetal condition during labour is inferredfrom a continuous visual recording of the fetal heart rate and uterine contractions, called the cardiotocogram (CTG). DifJiculties in CTG interpretation is a major problem that can lead to both unnecessary Caesarean sections and damage to the infant. Our group has developed an intelligent system which applies expert(More)
