The risk of miscarriage is directly related to the severity of vaginal bleeding. In patients with 1st trimester vaginal bleeding, a retroplacental hematoma, in contrast to a marginal subchorionic hemorrhage is more predictive of subsequent miscarriage There is not a direct relationship between the size of a subchorionic hematoma and outcome Figure 15 – Chorionic bump arrow protruding into a gestational sac. An incomplete miscarriage results in a heterogeneously thickened endometrial lining.

Development Scans

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.

Here’s info on the risks vs. rewards of pregnancy ultrasounds – plus a “middle way” to help you reap all the benefits and minimize the dangers.

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.

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.

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.

Aetna considers detailed ultrasound fetal anatomic examination experimental and investigational for all other indications including routine evaluation of pregnant women who are on bupropion Wellbutrin or levetiracetam Keppra , pregnant women with low pregnancy-associated plasma protein A, and pregnant women who smoke or abuse cannabis. There is inadequate evidence of the clinical utility of detailed ultrasound fetal anatomic examination for indications other than evaluation of suspected fetal anatomic abnormalities.

Detailed ultrasound fetal anatomic examination is not considered medically necessary for routine screening of normal pregnancy, or in the setting of maternal idiopathic pulmonary hemosiderosis. CPB – Fetal Echocardiograms. Ultrasonography in pregnancy should be performed only when there is a valid medical indication.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes.

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.

Other studies have found that dating from the last menstrual period was just as accurate as dating from an ultrasound. Better yet, use our advanced due date calculator to determine a more accurate result than standard due date calculators. Keep in mind as ultrasounds get later and later during the pregnancy, they become much less reliable in predicting accurate due dates.

Ideally, a dating ultrasound would need to be done in the first trimester, usually around weeks gestation. Sex of baby An obvious benefit to a baby ultrasound is learning the sex of your baby.

The last hydrolysis that releases the active oxytocin nonapeptide is catalyzed by peptidylglycine alpha-amidating monooxygenase PAM. By chance, sodium ascorbate by itself was found to stimulate the production of oxytocin from ovarian tissue over a range of concentrations in a dose-dependent manner. It is then released into the blood from the posterior lobe neurohypophysis of the pituitary gland. These axons likely, but dendrites have not been ruled out have collaterals that innervate neurons in the nucleus accumbens , a brain structure where oxytocin receptors are expressed.

In the pituitary gland , oxytocin is packaged in large, dense-core vesicles, where it is bound to neurophysin I as shown in the inset of the figure; neurophysin is a large peptide fragment of the larger precursor protein molecule from which oxytocin is derived by enzymatic cleavage. Secretion of oxytocin from the neurosecretory nerve endings is regulated by the electrical activity of the oxytocin cells in the hypothalamus.

5 Fascinating Facts About Fetal Ultrasounds
