This retrospective study examines the outcome of pregnancy after 28 weeks gestation in 100 consecutive, unselected primiparae who were aged 40 years or more. Antenatally, the incidence of hypertension was increased. There was an increased incidence of induction of labour and caesarean section. There were no maternal deaths and no ...
Augensen K - - 1987
In a prospective randomised study of mothers referred for prolonged pregnancy (around the 42nd week) 214 (group 1) were submitted to attempted induction of labour and 195 (group 2) assigned to continue for a further week without intervention. Strict selection criteria were used for the certainty of term. Mothers in ...

Recent experimentally derived evidence has confirmed earlier suggestions that seizures which occur within 48 h of birth in babies born at or later than 37 completed weeks gestation are particularly likely to reflect intrapartum asphyxia. We have compared 54 cases of such seizures with 41,090 controls in a geographically defined ...

Spontaneous fetomaternal haemorrhage is an important, but usually overlooked, cause of perinatal mortality and morbidity. Although fetomaternal bleeding in the third trimester of pregnancy is common it is normally less than 0.1 ml. A fetal macrotransfusion (greater than 5 ml) is uncommon, but is important because it is insidious, unexpected ...

300 patients at high fetal risk (mean gestational age 34 wk) were randomised to a group for antenatal doppler umbilical artery waveform studies and a control group. The timing of delivery was similar in the control and doppler-report-available groups overall. However, in the report group obstetricians allowed the pregnancies of ...
Floberg J - - 1987
The influence of pelvic outlet capacity on fetal head presentation in 1,402 term primiparas with normal pregnancies was studied. In all cases radiological pelvimetry was carried out and labor started spontaneously. Occiput posterior (OP) delivery occurred in 5.1%. As pelvic outlet capacity decreased an increased frequency of OP presentations and ...

Serum relaxin immunoactivity was measured by means of a porcine radioimmunoassay in a cross-sectional study of 302 normal singleton pregnancies. Concentrations in the third trimester were lower than in early and mid pregnancy. At term, relaxin levels in patients who went into spontaneous labour within a week of sampling were ...
Price J H - - 1986
Labour was induced in 32 high-risk twin pregnancies and the outcome compared with that in 32 twin pregnancies ending in spontaneous labour. No significant differences were found between the groups in terms of duration of labour and mode of delivery, and there were no failures of induction. Perinatal outcome was ...
Berger P J - - 1986
We quantified the respiratory activity of 9 fetal lambs using computer-analysis of the diaphragmatic electromyogram (EMG) obtained during 2 h recording sessions interspersed over the last 13 days of gestation. The fetuses delivered unassisted at an average gestational age of 145 days (term = 147 days). During the last 2 ...

Prostaglandins, particularly PGE2 vaginally, can be valuable for cervical ripening or induction of labour in some women. Ease of use must not be allowed to result in unjustified intervention. Amniotomy followed by oxytocin infusion are the methods of choice for induction of labour. Careful monitoring of the maternal and fetal ...
Kadar N - - 1986
The duration of second stage labour was studied, retrospectively, among 410 primigravidas who received epidural analgesia in the first stage of spontaneous labour at term (greater than 37 weeks). Survival analysis was used to investigate how the likelihood of a spontaneous delivery was related to time spent in the second ...
Omer H - - 1986
Two studies on the relationship of psychological variables and premature labour were conducted. The first was a retrospective comparison of psychopathological tendencies, attitudes towards pregnancy, physical complaints during pregnancy and perceived marital and social support, between a group of women who had premature labour and a group of women with ...
Hastings M J - - 1986
Vaginal colonisation of pregnant women with group B streptococci (GBS) was not related to age, parity or blood group. There were marked differences between racial groups, Asians having a low colonisation rate and Negroes a high rate. Vaginal GBS colonisation was associated with intrapartum pyrexia, but not with preterm labour, ...
Lampé L G - - 1986
Maternal and foetal results of 2020 elective inductions of labour are presented, compared with those of 2750 pregnancies in which labour was not induced during the 40th week of gestation, awaiting for its spontaneous onset. The morbidity, mortality, and the frequency of obstetric operations during labour were compared. In all ...
Schweikhart G - - 1986
Based on a new concept of maturation of the placental villous tree and its disorders (synchronous and asynchronous immaturity, asynchronous maturity, hypermaturity, and terminal villi deficiency) we studied the possible effect of the placental villous tree on the premature onset of labour. In mature normal neonates irregular and asynchronous villous ...
Silva-Cruz A - - 1985
Fifty women (25 nulliparae and 25 multiparae) with unfavorable cervix at term were enrolled in a clinical experiment to evaluate the safety and efficacy of the intracervical application of 0.5 mg PGE2 gel for cervical softening and eventual induction of labour; duration of pregnancy (38-42 wk) was confirmed by ultrasonic ...
Crawford J S - - 1985
A review of the maternal complications encountered in a consecutive series of over 27 000 lumbar epidural blocks (exclusive of epidurals administered for elective Caesarean section and complications of a relatively minor or fleeting nature) in a single obstetric unit is presented. There were nine potentially life threatening complications, of ...

A prospective blind study of non-stress antenatal cardiotocography was undertaken in a group of 216 'high risk' pregnancies. The 'Cardiff' scores and the outcome of the pregnancies were compared subsequently. Low scores were associated with infants that were small-for-gestational age and fetal distress in labour, while high scores were associated ...
Hanssens M C - - 1985
Peripheral plasma concentrations of unconjugated oestradiol-17 beta, progesterone and total oestriol were measured in patients presenting with uncomplicated preterm labour. Control samples were obtained from normal healthy women matched for maternal age, parity and duration of pregnancy. Oestrogen concentrations were often higher and progesterone concentrations often lower in patients presenting ...

A peroxidase anti-peroxidase staining technique was used to determine the presence of pregnancy-associated prostaglandin synthetase inhibitor (PAPSI) in human amniotic epithelium from 20 pregnant women at 36-40 weeks' gestation. PAPSI was present in amniotic epithelial cells in 12 of 15 women before the onset of labour. No PAPSI was found ...
Cohen S L - - 1985
It has been hypothesized that large amounts of estriol (E3) are produced during human pregnancy to ensure a quiescent uterus during prelabour pregnancy by combining with most of the myometrial nuclear receptors, leaving an inadequate number for a stimulatory estradiol (E2) concentration. It is further hypothesized that the amount of ...
Tjugum J - - 1985
Fetal membranes were obtained in connection with 1st-trimester abortion and vaginal delivery or elective caesarean section at term. Pieces of the isolated amnion membrane were incubated in vitro with [3H]proline or [3H]glucosamine in the presence of prostaglandin (PG) E2 or oxytocin. PGE2 reduced the labelling with [3H]proline in the 1st ...
Illingworth R S - - 1985
It is irrational to ascribe a child's so called 'brain damage' to labour or delivery without considering other factors. 'Brain damage' occurs without difficult labour or perinatal hypoxia and caesarean section is no guarantee against it. Severe difficulties in delivery and severe hypoxia at birth are in the great majority ...
Parkington H C - - 1985
Spontaneous electrical and mechanical activity were measured in strips of circular myometrium, stretched to in vivo length, obtained from ewes during pregnancy and parturition. The resting tension was high (280 mN/mm2) early in pregnancy and decreased gradually during the course of gestation to reach low levels (20 mN/mm2) during labour. ...
Wiqvist N - - 1985
Systematic studies using a superfusion technique for recording myometrial contractility in vitro have been conducted in our department to explore whether prostaglandins (PG) have a differential action on the different segments of the pregnant uterus and also whether the qualitative and quantitative response undergoes a change during spontaneous labour. Myometrial ...
Mazor M - - 1985
Over a period of one year 312 high-risk patients (HRP) were prospectively monitored using ultrasound score (USS), nonstress test (NST) and contraction stress test (CST). There were nine cases with low USS, seven of them had reactive NSTs, were delivered vaginally without any evidence of distress in labour and had ...
Müller H - - 1985
Haemodynamic investigations, partly using invasive monitoring, concerning interactions between the beta-mimetic effect of fenoterol and the alpha-sympathetic blockade of spinal or epidural anaesthesia were made in a total of 49 patients during pregnancy, during caesarean section and in non-pregnant women. Haemodynamic effects of fenoterol during regional anaesthesia were compared with ...
Curzen P - - 1984
A prospective study of 6825 labours was undertaken to determine the relation between the Apgar scores of the babies at one minute and the cardiotocograph tracing in labour. The sensitivity of an abnormal tracing was 35.2% for babies who needed intermittent positive pressure ventilation and 20.0% for babies who did ...
Thomsen S G - - 1984
Fifteen women were studied during the second stage of labour by measuring simultaneously fetal transcutaneous carbon dioxide tension (Tc PCO2 and maternal end-expiratory PCO2. A linear increase of Tc PCO2 with time was observed, predominantly because of changing maternal respiration patterns. The degree of maternal hyperventilation had no adverse effect ...
