A five year retrospective study (1984-1989) was undertaken on 24 consecutive patients with fetal death to ascertain the efficacy, side effects and complications associated with a combination of extra-amniotic prostaglandin E and intravenous oxytocin to induce labour. Six patients with primigravidae and eighteen multigravidae with inductions carried out at gestations ...
Giraldi A - - 1990
Oxytocin (OT) binds to specific receptors of myometrial cells, inducing and increasing myometrial contractions. During pregnancy and especially close to term, an increase in the myometrial OT-receptor concentration is found, leading to an increased sensitivity of the myometrium towards circulating OT. The factors determining the receptor level are not completely ...

Three hundred and forty short statured mothers (height less than 145 cm) were compared with 680 mothers (height more than 145 cm) who served as control to isolate problems associated with pregnancy and labour in the former. Short statured mothers hailed from poorer social class and had an unhealthy family ...
Newbold S - - 1989
The T/QRS ratio of the fetal ECG was obtained during labour from 25 women with normal pregnancies. The poor signal-to-noise ratio of the unprocessed signals, chiefly due to baseline wander, led to a wide variation between individual measurements. This problem was overcome by data averaging, the ratio being expressed as ...
Fairlie F M - - 1989
Doppler signals were recorded from the umbilical arteries in 103 women during labour. The pulsatility index (PI) did not alter with progress in labour. During uterine contractions the PI showed a change only if there was a deceleration in the fetal heart rate. Low birthweight (less than 10th centile) and ...
