Am J Obstet Gynecol ; 5: Nutrition A woman carrying twins has unique nutritional needs, especially for additional calories. Because the patient most often experiences early satiety and loss of appetite, we recommend a consult with a nutritionist to address this and other issues. She must increase her daily dietary intake by about calories per day, calories more than a woman carrying a singleton gestation. High-protein shakes are recommended given the high nutritional value.

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.

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.

To ultrasound or not to ultrasound? That is the question. For most pregnant mamas, ultrasounds are just a given. As a natural mama, we want to avoid as many interventions as possible during pregnancy and birth. Some studies also found that when women had an ultrasound for dating they were less likely to be induced for post-term pregnancy. However, if you have a practitioner like a midwife who is ok with continuing to closely monitor a post-term pregnancy, this may not be an issue for you.

Having this information in advance of the birth means that healthcare staff as well as parents can better prepare themselves for the delivery of a child with a health problem. For example, Down Syndrome is associated with cardiac defects that may need intervention immediately upon birth. Many expectant parents would like to know the sex of their baby before birth.

Methods include amniocentesis with karyotyping , and prenatal ultrasound. In some countries, health care providers are expected to withhold this information from parents, while in other countries they are expected to give this information. Since screening tests yield a risk score which represents the chance that the baby has the birth defect, the most common threshold for high-risk is 1:

Sims does have a controversial medical past.

Prior to the 18th century, caring for pregnant women in Europe was confined exclusively to women, and rigorously excluded men. The expectant mother would invite close female friends and family members to her home to keep her company. The presence of physicians and surgeons was very rare and only occurred once a serious complication had taken place and the midwife had exhausted all measures to manage the complication.

Calling a surgeon was very much a last resort and having men deliver women in this era whatsoever was seen as offending female modesty. However, the subject matter and interest in the female reproductive system and sexual practice can be traced back to Ancient Egypt [6] and Ancient Greece. Living in the late first century A. After the death of Soranus, techniques and works of gynecology declined but very little of his works were recorded and survived to the late 18th century when gynaecology and obstetrics reemerged.

These advances in knowledge were mainly regarding the physiology of pregnancy and labour.

All rights reserved Note: The subject of prenatal testing for Down syndrome is an emotionally charged one. I am presenting this essay as a guide to parents who are faced with the prenatal tests offered by their doctor. If your fetus has been diagnosed as having Down syndrome or is simply at high risk, please spend some time to learn more about the condition. This booklet is available at www. Introduction Over the last 20 years, new technology has improved the methods of detection of fetal abnormalities, including Down syndrome.

While there are ways to diagnose Down syndrome by obtaining fetal tissue samples by amniocentesis or chorionic villus sampling, it would not be appropriate to examine every pregnancy this way. Besides greatly increasing the cost of medical care, these methods do carry a slight amount of risk to the fetus. So screening tests have been developed to try to identify those pregnancies at “high risk.

What is the difference between a screening test and a diagnostic test? In diagnostic tests, a positive result very likely means the patient has the disease or condition of concern. In screening tests, the goal is to estimate the risk of the patient having the disease or condition. Diagnostic tests tend to be more expensive and require an elaborate procedure; screening tests are quick and easy to do. However, screening tests have more chances of being wrong:

Obstetric & Gynaecological Imaging Practice

Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations.

Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels. The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle.

Becoming a skilled surgeon takes practice, therefore residents often “come in early and stay late” to learn surgery and care for extremely sick patients.

High School Many physicians know they want to become a doctor during high school or even earlier. In many respects the training of a doctor begins as early as high school, where the future doctor must obtain grades high enough to be accepted to a 4-year college. Students must balance the need for high grade point average GPA with their social needs, such as sports, dating, and school events.

College In college, students hoping for an acceptance into medical school must take a large number of required science courses, such as biology, chemistry, genetics, physics, and organic chemistry. Some medical schools also require one or more writing or literature classes. Most “pre-med” students major in biology, chemistry, or physics. Some schools have a “pre-med” major while others do not. However, a number of college students major in non-science disciplines or have dual majors, for example in literature and biology.

As long as a student takes the required courses to gain acceptance into medical school the major is not particularly important, and, to my knowledge, medical school admission committees do not favor one major over another. College is an extremely stressful time for many pre-med students. Science classes are generally more rigorous than non-science classes, in part due to the huge volume of material, and also because of labs. Labs usually occur in the afternoon after regular classes are over, and I can recall many afternoons where I would look out the lab window and watch other students heading to the pool or beach!

Pre-med students all know that excellent grades, usually above 3. A “C” in a particular class may mean an academic death sentence to a worried student, so dedicated studying is the norm, often at the expense of athletics and social activities.

You may like to take a look at charts for crown-rump length , biparietal diameter , femur length , abdominal circumference , gestational sac diameter , yolk sac diameter and intrauterine fetal weight. 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. You can visit the page here. I am pregnant for 7 weeks.
