The first is a screening test for Down’s Syndrome, Trisomy 13 and Trisomy 18, and the second is to establish who has a high risk pregnancy with regards to Down’s Syndrome, Trisomy 13 and Trisomy With the use of ultrasound between the gestational ages of 12 to 13 weeks, the thickness at the back of your baby’s neck is measured. This measurement is very specific and only trained accredited operators are able to do this scan. The Nuchal Translucency scan does not diagnose your baby as having these genetic abnormalities but establishes a risk in combination with your blood test results. The results of your scan are sent to your referring doctor and they will discuss the results with you at your next appointment. It is important that you follow up these results with your referring doctor. In order to take an accurate measurement your baby needs to be in a very specific position to meet all the criteria for an accurate measurement.
Obstetric & Gynaecological Imaging Practice
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. At this time a study is done to scan the fetal organs and dating parameters for growth and weight, and determine the general well being of the fetus.

Urine protein and glucose determination X Screening for TB if at risk Genetic screening , including 1st-trimester screening for aneuploidy Pelvic ultrasonographyg aComponent may not be detectable depending on the stage of pregnancy at presentation. If a woman has Rh-negative blood, she may be at risk of developing Rh0 D antibodies, and if the father has Rh-positive blood, the fetus may be at risk of developing erythroblastosis fetalis.
Rh0 D antibody levels should be measured in pregnant women at the initial prenatal visit and again at about 26 to 28 wk. At that time, women who have Rh-negative blood are given a prophylactic dose of Rh0 D immune globulin. Additional measures may be necessary to prevent development of maternal Rh antibodies. Generally, women are routinely screened for gestational diabetes between 24 and 28 wk using a g, 1-h glucose tolerance test. However, if women have significant risk factors for gestational diabetes, they are screened during the 1st trimester.
Abnormal results on both tests confirms the diagnosis of gestational diabetes. In some pregnant women, blood tests to screen for thyroid disorders measurement of thyroid-stimulating hormone [TSH] are done. Estimates of gestational age are based on measurements of fetal head circumference, biparietal diameter, abdominal circumference, and femur length. Measurement of fetal crown-rump length during the 1st trimester is particularly accurate in predicting EDD:

The role of ultrasonography in obstetric practice has continuously evolved since its introduction more than 40 years ago. Indeed, it is difficult to imagine a modern obstetric practice without access to the information provided by real-time ultrasound.
Underestimation of gestational age by conventional crown-rump length growth curves. Reprinted with permission of American College of Obstetricians and Gynecologists Variations in the measurement of CRL can be attributed to differences in fetal growth patterns. Such differences are related to factors similar to those that influence birth weight curves, including maternal age and parity, prepregnancy maternal weight, geographic location, and population characteristics.
These include incorporation of the yolk sac or lower limbs in the CRL measurement, excessive curling or extension of the fetus, and tangential section of the trunk. The biparietal diameter BPD is one of the most commonly measured parameters in the fetus. Campbell was the first investigator to link fetal BPD to gestational age 20 ; however, since this original report, numerous publications on this subject have appeared in the literature.

Sonographer doing an echocardiogram in a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart’s left ventricle Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient’s clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient’s care. Transthoracic echocardiogram A standard echocardiogram is also known as a transthoracic echocardiogram, or cardiac ultrasound.
In this case, the echocardiography transducer or probe is placed on the chest wall or thorax of the subject, and images are taken through the chest wall.
The abdominal circumference (measurement around the waist of the fetus) is the single most sensitive indicator of fetal growth. A single series of measurements at one point in time can diagnose a small or a large fetus, but the overall growth pattern can only be assessed over at .

The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. Accurate dating of pregnancy is important to improve outcomes and is a research and public health imperative. As soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained, the gestational age and the estimated due date EDD should be determined, discussed with the patient, and documented clearly in the medical record.
Subsequent changes to the EDD should be reserved for rare circumstances, discussed with the patient, and documented clearly in the medical record. When determined from the methods outlined in this document for estimating the due date, gestational age at delivery represents the best obstetric estimate for the purpose of clinical care and should be recorded on the birth certificate. For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the last menstrual period alone, should be used as the measure for gestational age.
Recommendations The American College of Obstetricians and Gynecologists, the American Institute of Ultrasound in Medicine, and the Society for Maternal—Fetal Medicine make the following recommendations regarding the method for estimating gestational age and due date: For instance, the EDD for a pregnancy that resulted from in vitro fertilization should be assigned using the age of the embryo and the date of transfer.
Obstetric Ultrasound Skills the basics and beyond
With that in mind, one must look at prenatal care in the context of risk assessment, health promotion, and risk-directed intervention in general and not just from an obstetrical perspective. This means that a large range of issues must be systematically and consistently addressed and documented during prenatal care. If one were to attempt to make an analogy between prenatal care and building a house, the prenatal record might be seen as the blueprint and checklist for construction, and the initial prenatal visit as the foundation and framework on which the rest of the structure is built.
Good prenatal care depends on many factors but clearly is facilitated by a good prenatal record. Additionally, the prenatal record both guides and documents the delivery of good prenatal care. Prenatal records have evolved considerably in the past three decades and may be better developed than any other specific medical record-keeping system.

It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests.
Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening. Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis.
MEDICAL PROVIDERS’ GUIDE TO MANAGING THE CARE OF DOMESTIC VIOLENCE PATIENTS WITHIN A CULTURAL CONTEXT Michael R. Bloomberg Mayor City of New York.
In this exclusive MedPage Today video, Richard Todd Ivey, MD, of Texas Children’s Hospital in Houston, says that while research has shown that some low-risk women may derive a benefit from monitoring their own blood pressure and fetal heart rate, as well as performing urine dips at home, this population must be carefully selected.
Following is a transcript of his remarks: Initial visits with a healthcare provider during early pregnancy are absolutely critical. What this allows the provider to do is obtain accurate dating, so that if there were any complications that arose later in the pregnancy, the dating is never a question. It will also allow for identification of risk assessment — things such as substance use or abuse, exposure to medications and potential teratogens, the need for any genetic studies as determined by a family history.
Also, the identification of pertinent medical and or surgical history. There also should be a physical exam and then appropriate laboratory testing, and again a major provision — excuse me — a major intervention at that time would be prenatal education. We know multiparous women who have no known complications who have been adequately educated and screened may actually need fewer prenatal visits, which may actually overall improve their care provided they’re taught the right things to do as far as blood pressure monitoring, maybe urine dips or urinalysis monitoring and assessment of fetal heart tones.
However, in many of our populations that are labeled typically high-risk, meaning they have other complications, whether it’s maternal or fetal complications, this may not be appropriate. There is current research going on looking at the number of prenatal visits and could this in some way be reduced to maybe lower overall healthcare costs.
And in certain patient populations, there may be a potential benefit to this. In a multiparous patient without obstetric or gynecologic complications, and certainly no fetal or otherwise maternal complications — truly a low-risk population — there may be some benefit to this, provided that adequate education is given.
