First trimester ultrasounds

Contact details Overview The RCOG curriculum now requires that all trainees have practical training in basic obstetric ultrasound, comprising two modules on early pregnancy ultrasound weeks and ultrasound assessment of fetal size, liquor and the placenta. These two practical modules need to be underpinned with a sound theoretical basis, which this course is designed to offer. It also will serve as the basis for those trainees developing their skills further with the intermediate ultrasound modules both in obstetrics and gynaecology. This is primarily a theoretical course however, this course will provide opportunity for basic hands on training in the basic technique of TV ultrasound and TA assessment of pregnancy. The focus will be on technique and practical training to enhance the scan image quality, providing participants with an opportunity to put the theory of the early morning lectures into practice.

Obstetric cholestasis Work out your due date Ultrasound scans in pregnancy. The dating scan can include a nuchal translucency (NT) scan, which is part of the combined screening test for Down’s syndrome, if you choose to have this screening.

Screening for pre-eclampsia high blood pressure in pregnancy What else is the scan called? What part of the baby will be seen? You will notice a dramatic difference in the anatomic detail visible in your baby on this scan when compared to the 12 week scan. The ultrasound will endeavour to evaluate the fetal brain, face, spine, heart, lungs, stomach, kidneys, bladder, cord insertion at the belly button, arms and legs, placenta cervix and amniotic fluid.

Can all abnormalities be seen? An amazing amount of detail can often be seen. However it is important to realize that not all parts of the baby show up well with ultrasound. No ultrasound examination can ever guarantee a normal fetus. The best centres in the world consistently report on the limitations of ultrasound and its inability to detect all fetal abnormalities. Up to half the fetal heart defects will not be seen. Some of these are only minor, but some may not be apparent until the fetus is bigger, later in the pregnancy.

Many bone growth problems, forms of dwarfism, will only be possible to be suspected late in pregnancy and the diagnosis is made on x-rays taken after the baby is born. What about diagnosing Down syndrome?

Ultrasound for Pregnancy

International conference on transition and cord clamping at birth April It is increasingly recognised that the circulatory changes involved in transition at birth cannot occur within a few seconds of birth. While the healthy fetal circulation and the healthy neonatal circulation are moderately well understood, the underlying triggers, the precise sequence and speed of the changes in the circulation are not.

How can we interefere in something we do not understand? Nearly all textbooks and journals which include the physiological transition of the neonate at birth describe a marked change in the peripheral vascular resistance and an increase in the afterload of the heart. One notable exception is Gray’s Anatomy.

Rather, this scan is necessary for a known or suspected fetal anatomic or genetic abnormality (i.e., previous anomalous fetus, abnormal scan this pregnancy, etc.), or increased risk for fetal abnormality (e.g. AMA, diabetic, fetus at risk due to teratogen or genetics, abnormal prenatal screen).

What are the limitations of Obstetrical Ultrasound Imaging? What is Obstetrical Ultrasound Imaging? Ultrasound is safe and painless, and produces pictures of the inside of the body using sound waves. Ultrasound imaging, also called ultrasound scanning or sonography , involves the use of a small transducer probe and ultrasound gel placed directly on the skin. High-frequency sound waves are transmitted from the probe through the gel into the body.

The transducer collects the sounds that bounce back and a computer then uses those sound waves to create an image.

The Decision is Yours. Initial OB visit- The study is done to verify pregnancy, determine the gestational age, obtain fetal heart tones, and search the adnexal region for pelvic masses. At this stage in your pregnancy a study is done to determine the fetal heart rate, the dating parameter, and fetal activity movement of limbs.

However, to be effective it is recommended that scanning services follow standard protocols based on national guidelines and that scanning practice is audited to ensure consistency. Bradford has a multi-ethnic population with one of the highest rates of birth defects in the UK and it requires an effective foetal anomaly screening service.

We implemented a rolling programme of audits of dating scans, foetal anomaly scans and growth scans carried out by sonographers in Bradford. All three categories of scan were audited using measurable parameters based on national guidelines. Following feedback and re-training to address issues identified, re-audits of dating and foetal anomaly scans were carried out. In both cases, sonographers being re-audited had a marked improvement in their practice.

Analysis of foetal abnormality detection rates showed that as a department, we were reaching the nationally agreed detection rates for the Fetal Anomaly Screening Programme auditable conditions. Audit has been shown to be a useful and essential process in achieving consistent scanning practices and high quality images and measurements. Obstetric audit, foetal anomaly screening programme, foetal measurements Introduction Ultrasound has been used successfully for several decades for the detection of specific foetal abnormalities.

However, its value as a screening tool has been more difficult to demonstrate.

Practical Obstetrical Ultrasound, p Rockville, MD, Aspen, Averaging the gestational ages derived from two or more measurements has been shown to be more accurate than using any single parameter. Because of the greater accuracy of the early study, ultrasound examinations subsequent to an early study should not be used to revise the estimated date of confinement EDC , but rather should be used as a measure of the quality of fetal growth between the two studies.

Similarly, it is not appropriate to revise an EDC on the basis of an ultrasound examination if the patient’s menstrual dates are within the range of error of the ultrasound method. If significant discrepancy is seen between two ultrasonographically measured fetal dimensions more than a 2-week difference , then the ultrasonographer must consider the possibility of an error in measurement technique. If a critical reevaluation reveals no error, then asymmetry in fetal growth may be present.

Growth asymmetry may occur as a result of physiologic alteration in fetal head shape brachycephaly or dolichocephaly or in association with intrauterine growth restriction IUGR , macrosomia, or a fetal anomaly. The survey includes a confirmation of fetal number, viability, position, assessment of amniotic fluid volume, and location of the placenta. In assessing fetal biometry, the applicable standard fetal measurements already discussed, including CRL, BPD, abdominal circumference, and femur length, should be taken.

The estimation of fetal weight is a clinically useful parameter computed from the fetal biometric measurements. Several equations have been produced based on fetal biometry that estimate fetal weight. One or more of these usually is incorporated into the software of most contemporary ultrasound machines.

Am I pressing too hard? I wonder, of course, if she sees what I see—a cleft lip and palate. In all likelihood, you also are relieved at escaping the discomfort of delivering bad news to your patient. After all, every patient wants to know her pregnancy is progressing as expected and her fetus is developing normally. It also can be difficult for you to tell your patient there is a problem. But as a practitioner, you must be prepared to deliver all results, good and bad, to your patients.

Obstetric Ultrasound is the use of ultrasound scans in pregnancy. Currently used equipments are known as real-time scanners, with which a continous picture of the moving fetus can be depicted on a .

Can the scan show the gender of my baby? What is actually done? Scans are usually performed by a doctors, midwives or radiographers who are specially trained in ultrasound, and are known as sonographers. The whole pregnancy will be assessed. The amount of liquor amniotic fluid , the position and appearance of the placenta and a detailed scan of the baby itself.

The baby will be measured, and the anatomy examined in detail. It is recommended that all pregnant women have a scan in the first trimester at around 12 weeks of pregnancy to confirm their dates. First trimester ultrasonic scans may show ‘soft’ markers for chromosomal abnormalities, such as an increased fetal nuchal translucency back of the neck to enable detection of Down’s syndrome fetuses.

Some studies are cited as being too small or having too many confounding factors to draw any useful conclusions. It is difficult to know what to believe Today, millions of ultrasound exams have been performed and millions of babies have been exposed during pregnancy. Without dramatic birth defects to stop its use, more subtle biological sequela may go unrecognized for years to come.

Training Videos. The following videos will teach the principles of pregnancy ultrasound, infection control, fetal anatomy, how to date a pregnancy, maternal pelvic anatomy, how to examine amniotic fluid volume, placenta anatomy, fetal presentation, how to identify certain serious complications (such as bleeding, ectopic and multiple gestation pregnancy, and intrauterine growth restriction.

If you have problems understanding and calculating your due date, check out and download a copy of the Ob calculator by York Winston. Hutchon’s site and the Gestation Network also provide pregnancy calculators. A large number of mails I received are about fetal anomalies, I have therefore tried to put together a Catalogue of Web pages which describe in some detail specific congenital anomalies that are diagnosable by ultrasound.

They made me drink 4 cups of water and my bladder was almost bursting at the end of the session. Is this really necessary? A full bladder is usually necessary when the scan is done abdominally and in the early part of pregnancy. This would tend to lift the uterus up a little bit and being in front displaces the bowels away and act as an echo-lucent windows for the ultrasound to pass through.

Ultrasound doesn’t go through air as in the bowels well but transmits perfectly through liquid as in the case of the urine in the bladder. Your doctor will be able to see things so much more clearly with the full bladder there especially the presence or absence of fetal heart beat. In a vaginal scan however, a full bladder will not be necessary.
