BACKGROUND Ultrasound examination of pregnancy before 24 weeks gestation may lead to more accurate dating and earlier diagnosis of pathology, but may also give false reassurance. It can be used to monitor development or diagnose conditions of an unborn baby. This review compares the effect of routine or universal, ultrasound examination, performed before 24 completed weeks' gestation, with selective or no ultrasound examination. OBJECTIVES: To assess the effect of routine pregnancy ultrasound be...

We have used magnetic resonance imaging (MRI) to provide important new insights into the function of the human placenta in utero. We have measured slow net flow and high net oxygenation in the placenta in vivo, which are consistent with efficient delivery of oxygen from mother to fetus. Our experimental evidence substantiates previous hypotheses on the effects of spiral artery remodelling in utero and also indicates rapid venous drainage from the placenta, which is important because this outflow...

Abstract Objectives To determine which ultrasound measurement for predicted fetal macrosomia most accurately predicts adverse delivery and neonatal outcomes. Study Design Four biomedical databases searched for studies published after 1966. Randomised trials or observational studies of women with singleton pregnancies, resulting in a term birth who have undergone an index test of interest measured and recorded as predicted fetal macrosomia ≥28 weeks. Adverse outcomes of interest included shoulder...

Abstract Abnormal placental invasion is associated with increased maternal morbidity and mortality. In an abnormally invasive placenta (AIP), the placental villi are not confined by the innate barrier of the uterine endometrium and invade the uterine myometrium and potentially even the uterine serosa. During the antenatal period, signs of abnormal invasion can be seen on ultrasound from as early as the first trimester. Typically, placental lacunae, a thin myometrium, abnormal blood flow in the p...

Background Epidural analgesia in labour prolongs the second stage and increases instrumental delivery. It has been suggested that a more upright maternal position during all or part of the second stage may counteract these adverse effects. This is an update of a Cochrane Review published in 2017.

Background Labour is a period of significant physical activity. The importance of carbohydrate intake to improve outcome has been recognised in sports medicine and general surgery. Objectives To assess the effect of oral carbohydrate supplementation on labour outcomes. Search strategy MEDLINE (1966–2014), Embase, the Cochrane Library and clinical trial registries. Selection criteria Randomised controlled trials (RCT) of women randomised to receive oral carbohydrate in labour (<6 cm dilated), ver...

BACKGROUND: Fetal macrosomia is associated with an increased risk of adverse maternal and neonatal outcomes. OBJECTIVES: To compare the accuracy of antenatal two-dimensional (2D) ultrasound, three-dimensional (3D) ultrasound, and magnetic resonance imaging (MRI) in predicting fetal macrosomia at birth. SEARCH STRATEGY: Medline (1966-2013), Embase, the Cochrane Library and Web of Knowledge. SELECTION CRITERIA: Cohort or diagnostic accuracy studies of women with a singleton pregnancy, who had thir...

Objective: To study whether maternal cigarette smoking during pregnancy is associated with alterations in the growth of fetal lungs, kidneys, liver, brain, and placenta. Design: A case-control study, with operators performing the image analysis blinded. Setting: Study performed on a research-dedicated magnetic resonance imaging (MRI) scanner (1.5 T) with participants recruited from a large teaching hospital in the United Kingdom. Participants: A total of 26 pregnant women (13 current smokers, 13...

Key content Asylum seekers and refugees are a vulnerable group with regards to pregnancy outcomes and accessing maternity care. Asylum seekers and refugees who are pregnant and living in the UK face medical, sexual and psychosocial challenges, including dispersal late in pregnancy. The health needs of asylum seekers and refugees are complex but similar to other deprived and ethnic minority communities in the UK. Asylum-seeking women are three times more likely to die in childbirth and up to four...

Background Fetal macrosomia is associated with a number of complications, including shoulder dystocia and maternal and fetal birth trauma. Two dimensional ultrasound biometry has been shown to be inaccurate in diagnosing macrosomia. We performed a systematic review to compare 2D ultrasound with 3D and MRI methods. Methods Systematic review of the literature, with bivariate meta-analysis of sensitivity, specificity and positive (LR +ve) and negative likelihood ratios (LR-ve), with 95% confidence ...
