Studies of pursuit of the pregnancy

During the whole gestation, your doctor obstetra will make you do a series of studies of pregnancy that will help him to observe meticulously the evolution and development of your baby. At present, with the advance of the science and the technology to the service of the medicine, the studies of the pregnancy are much more precise than earlier.

In general, nowadays, the pregnancy studies do not have error margin, for which, there is easier the diagnosis of any illness, problem of development, or genetic malformation that could exist during the gestation.

The diagnosis anticipated by means of to these studies of the pregnancy serves for example, to make intrauterinas surgical interventions; or to know if there is fetal suffering; or to determine if the pregnancy is inside or out of the womb; or so that the parents are prepared before any genetic alteration; or to know almost with accuracy the probable date of childbearing, even to know the sex of the baby and the number (if it is the only one, or multiple pregnancy) etc.

In this space we will speak about the studies for that more commonly they ask during the pregnancy, and will tell of what each of these studies talks each other of pregnancy.

Ultrasound scans in 3D and 4D

Nowadays the diagnosis studies for images are realized by ultrasound, where irradiation does not exist, therefore it is innocuous for the baby and is not invasive. The resolution of these studies is very high, and the ultrasound scans that incorporate the technology three dimensions-3D - and those of four-4D-que measure in the time, offer a spatial vision that improves the interpretation of some images. It is possible to do in any moment of the pregnancy. It does not need previous preparation (for example, to drink waters down earlier).

Thanks to the ultrasound scans a baby one can estimate the risk of gestating with syndrome of Down or other alterations, as for example, cardiopat�as, across the measurement of the translucencia nucal, a species of ink pad located in the nape of the baby, whose thickness depends on the liquid that it contains.

In the first trimester (from the week 6 until the week 13):
This study observes the characteristics of the sack gestacional; the presence of the embryo; the cardiac activity of the embryo; after the week 9, the activity of the embryo, and the presence of the cephalic pole.

In the second pregnancy trimester (after the week 14):
The vertebral axis is studied; the cephalic pole; the corporal activity and of the members; the development placentario; and the implantation of the umbilical cord.

After the week 18, it is important to realize the anatomical esc�n of the fetus, where they will be studied meticulously: each of the bones of the members, seeing in detail feet and hands; the vertebral axis; cephalic pole; abdominal and thoracic cavity, where it will be possible to visualize 4 cardiac cameras, the fetal diaphragm, the gastric filling and vesical. Also a meticulous observation of the fetal face, afterbirth and drawstring.

In the third trimester:
There is important the pursuit of the growth and fetal development; and to study the thickness and maturation of the afterbirth. From the week 18 it is possible to know the sex of the baby, any time the position and his movements allow it.

The ultrasound scan Doppler:
This study serves like complementary tool for the diagnosis of the functioning placentario and the evaluation of the growth and the fetal nutrition. The skill is based on the effect Doppler, which measures sound when it goes and when it comes from a sonorous source (the same effect that does that we listen to a car of a form when it comes closer and other one when it moves away).

Fetal monitoring:

It is a study that he gathers simultaneously, the beats of the heart of the baby and the frequency and duration of the uterine contractions, showing them in a graph.

Two are placed captores in the abdomen of the mom, fixings with a flexible strip. This study is realized several times during the last weeks of the pregnancy, and during the childbearing work. Thus the doctor can monitorear if there is or not fetal suffering, and if the contractions are well. The synchronization of the contraction with the increase of the cardiac frequency of the baby must be neither the esperable, nor more beats not less. If they have occasion to listen to the beats, do not be scared: the heart of the baby beats normally almost to the double of the heart of an adult.

Dosaje of Estriol:

The Estriol study in blood (estriolemia), or it urinates (estrioluria) during the pregnancy, serves for the diagnosis of the fetal suffering, or any malfunction placentaria.

In two types of analysis, the Estriol is on the increase during the whole pregnancy, coming to his highest peak, towards the end of the same one. It is a question of a very well-known hormone how it is the estrogen, of big participation in all the processes of gestation.

The values of the Estriol are stabler in blood than in urine. According to medical criterion, these analyses will have to be indicated regularly. This way, the doctor will have a better situation picture.

Pregnancy diagnosis: Gonadotrofina cori�nica human (HGC):

The human gonadotrofina cori�nica is a hormone that is present during the pregnancy, from the ninth day of the gestation. This hormone is produced by the afterbirth. And it serves so that the embryo is not pushed back by the body of the mom. The detection of this hormone bases on the "subunit beta" of the structure of the protein, for which they will hear beta speaking often straight about the "subunit" to dry seasons.

This hormone is that they measure the test of pregnancy that is bought in the drugstore, and are very easy to do, and economic. They are realized by means of a sample of urine of at least 2 hours of retention. It is possible to realize at any time of the day.

A band puts itself it reactivates in the sample of urine, in a special receptacle that comes with the test. A few minutes are left, and if it proves to be two rayitas, it is a pregnancy, if it shows only one, you are not pregnant. Bear in mind that if it gives positive, there is no error, on the other hand if it gives negative, there can be error, or not have the quantity of days of gestation so that it receives the presence of human gonadotrofina cori�nica in the urine.
