Antenatal Appointments & Care

Antenatal Appointments & Care

Back to Pregnancy Reviews. The establishment of pregnancy dates is important not only for the mother who wants to know when to expect the delivery, it is also important for her carers, e. Various policies are applied whereby the LMP dates are used unless they have a discrepancy to the ultrasound dates of more than 7, 10 or 14 days. Reliance on LMP is fraught with various problems. But even if this date is accurate, the assumption that ovulation or conception occurs 14 days later is unfounded; there is a wide distribution with a positive skewness 3. Ultrasound scan biometry does have error but it is smaller and of a normal distribution.

Your scans

We provide a range of community services in Harrogate and the local area as well as across North Yorkshire and Leeds. At your initial booking appointment, you will be offered a range of important tests to screen for certain conditions that may affect your pregnancy. It is important for you to be aware that ultrasound scanning is a form of screening and is done to perform important checks on the health and development of your baby.

The combined test involves a blood test and a nuchal translucency NT ultrasound scan in the first trimester of pregnancy, normally at 12 weeks.

Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks​.

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.

Ultrasound Accuracy for Predicting Due Dates

All women will be offered ultrasound scans of their baby at around 12 and 20 weeks. Ultrasound scanning has been used extensively in pregnancy and is accepted to be safe.

During an ultrasound, a technician spreads a warm gel over the lower part of the abdomen, and then presses a tool called a transducer against the belly to examine the fetus using sound waves.

An image of the fetus appears on an accompanying computer screen. While looking at this image, the technician takes some standard measurements from different angles and listens for a heartbeat. Sonograms are risk-free, and seeing your baby will likely be an enjoyable experience.
