Antenatal surveillance of fetal growth is an essential part of good maternity care, as lack of detection of fetal growth restriction is directly associated with stillbirth and perinatal morbidity. New algorithms and guidelines provide care pathways which rely on regular third trimester ultrasound biometry and plotting of estimated fetal weight in pregnancies considered to be at increased risk, and their implementation has increased pressures on ultrasound resources.
Customised growth charts have improved the distinction between constitutional and pathological smallness and reduced unnecessary referrals. Their introduction, together with clinicians’ training, e-learning and audit as the key elements of the growth assessment protocol, has resulted in increased antenatal detection of small for gestational age babies and a reduction in avoidable stillbirths. However, missed case audits highlight that further improvements are needed, and point to the need to address quality assurance and resource issues in ultrasound services.
There has been a recent focus on stillbirth prevention, stimulated by the fact that stillbirth rates in the UK were among the highest in Western Europe and had not changed substantially over the last 20 years. However, independent case reviews into the care of pregnancies that ended with a stillbirth found that many were associated with substandard care and therefore potentially avoidable.
Many of these mothers never had a growth scan, and never even came to any special attention of the maternity services, until presenting one day — often late in pregnancy — with absent fetal movements. FGR was found to be the largest category, accounting for over half of all normally formed stillbirths. The Royal College of Obstetricians and Gynaecologists’ guidelines 6 for surveillance and management of pregnancies with an SGA fetal outlined a standard of care that included serial measurement and plotting of fundal height and ultrasound biometry in low- and high-risk pregnancies, respectively.
Customised charts which adjust growth curves according to maternal height, weight, parity and ethnic origin were recommended for plotting both fundal height and estimated fetal weight EFW.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
Dating scans are usually recommended if there is doubt about the validity of the last menstrual period. By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures.
