First ultrasound examination (ultrasound), the first documentary confirmation of pregnancy, the first photo of your future child, while in the form of a fruit egg in the uterine cavity - which is actually a pregnancy begins for a future mother.
Thus, ultrasound during pregnancy on early term is absolutely necessary, but still there are ideas about the dangers of ultrasound. Nevertheless, the safety of medical ultrasound is proved and reflected in international documents. Recommendations for reducing the duration of each BRC study are ethical, taking into account the concerns of future mothers regarding the ultrasound. So what is the possibility of ultrasound? With a delayed monthly, only 3-5 days, the ultrasonic scanner with a transvaginal sensor can register a master's pregnancy for a period of 2.5-3 weeks from the moment of conception. Ultrasound during early pregnancy allows you to determine the embryological term of pregnancy, since. The term calculated from the moment of fusion of the genital cells.
The countdown of the first day of menstruation taken in obstetrics may be inaccurate, it is difficult to determine the estimated moment of childbirth. In order to translate the embryological term of pregnancy into obstetrics, it is necessary to add 2-2.5 weeks to the embryology period. In the period of 2.5-3 weeks, the process of implantation blastocysts into the mucous membrane of the uterus is completed.
From now on, it is called a fruit egg and becomes accessible to research. In this period of blastocyst or embryonic chamber looks like a dark rounded or a drop-shaped formation, 4-5 mm in diameter. The embryonic chamber is surrounded by a shell and does not reflect ultrasonic waves, so. She is echonegative. The embryo and extraordinary organs have a microscopic structure and clutch localization, therefore are not yet visible with ultrasound: this period, the fruit egg looks like a homogeneous liquid. The scene of the implantation of the fetal egg is most often in the region of one of the pipe corners, but sometimes the localization of the fetal egg is located low, closer to the carriage. Such proximal localization occurs if the blastocyst moves into the uterine cavity within a few days after exiting the uterine pipe and only then implanted into the uterus wall.
If with a delay in menstruation in the ultrasound using ultrasound, a fruit egg is found, it is necessary to pass a survey in one or two weeks so that the fruit egg increases in size. The absence of a fetal egg during a re-examination should alert the doctor: in which case an ectopic pregnancy is possible. However, the diagnosis of ectopic pregnancy cannot be installed only with the help of an ultrasound, a more thorough examination is necessary.
In some cases, a rounded liquid education is found in the uteria, but laboratory and clinical data do not confirm the presence of pregnancy, the re-examination will help to diagnose the presence of a glandular polyp, cyst or myomatous nodule, outstanding in the uterine cavity. Rounded liquid education may be small. Such problems need to be solved only in a specialized institution that has a license to work with pregnant women. There you also need to pass and the ultrasound of the BRS (and any other period of pregnancy).
In the female consultation, the maternity hospital, the perinatal center is only a professional - an echoscopyist doctor - competent in the field of physiology and pathology of the female sexual sphere, obstetrics and applied embryology. Centers are currently very common providing services on the principle of "ultrasound in the world" - these centers do not provide a professional survey at the proper level and allow a large number of errors in diagnosis.
So, the pregnancy is detected, the fruit egg implanted into the wall of the uterus and increases very quickly in size. 17-20 mm - such a diameter of the fetal egg in four weeks of pregnancy. A fruit egg becomes oval, the sizes of the uterus increase slightly, and the asymmetry of its walls appears - one wall becomes thicker than the other. The embryo will be visible only in 5 weeks of pregnancy, and while the yelock bag is well different, in which the supply of nutrients for a developing embryo is stored. An oblong 5-week embryo is a few mm long, an amniotic leg is stretched to the inner surface of the fetal egg from the embryo. From this point on, the embryo can freely move in the liquid of the embryonic chamber - it leaves its interconnect position.
With 5-week pregnancy, one can already be determined, one embryo or two settled in the embryonic chamber. The number and structure of amniotic shells and chorion is the future placenta - determine the form of the future twins. If the embryonic material in the blastocyst is doubled - the one-way (monochorial) twin is developing with a fully identical set of chromosomes. Children from such twins are always alone and absolutely similar to each other.
But if there are two follicles in different ovaries in different ovaries, two pairs of sex cells merge and two blastocysts are formed, which are implanted and formed two fruit eggs with two embryos. In this case, a variety twin is formed - a bichorial or dichorial.
Such children are not twins in the strict sense of the word, because they have different sets of chromosomes, they can be of different sexes and no one like each other. 70% of born Films are a variety. But, except for the Film, there are still triples, and in general a multiple pregnancy.
There are various options for combinations of amniotic shells and chorions: so, the triple may consist of their two twins and one diverse with them. Uzi BRS easily identifies the type of twins or triple, but in the later dates it is more difficult to do it, so. Embryonic chambers will fill the entire cavity of the uterus.
Integrated health observation during pregnancy includes a mandatory periodic ultrasound during pregnancy in order to study the state and development of the fetus. Modern diagnostics makes it possible to identify possible deviations and malformations of development, which are a threat to health and life, both mother and the child.
Ultrasonic study during pregnancy is the main method of diagnostics, with the help of it is estimated by the biophysical fetal profile and the volume of accumulating waters.
The objectives of the ultrasound during pregnancy is to observe changes in the body's body and the state of the fetus. Thanks to this, the pathologies and malformations of the fetus development and defects are revealed and treatment as quickly as possible. Using ultrasound uterus, doctors can identify a lot - these are low, hernia and tumors, evaluate the state of the placenta and state the likelihood of the fruit (miscarriage).
When you can see a pregnancy on the ultrasound? The embryo is determined by ultrasound diagnostics on a period of 5 weeks. On the monitor screen, the tiny point is visible, behind which the whole life is hidden. The size of the embryo is only a few millimeters.
Ultrasound in early pregnancy (5-8 weeks) usually confirms the fact of pregnancy and determines the place of attachment of the fetus. It is called a transvaginal ultrasound during pregnancy. In this period, the placenta is not yet formed, and its function performs a yellow body. The resulting embryo is still called the "Embryon". It is located in a fruit egg that is attached to one of the walls of the uterus. The lifetime of crumbs is still so small that far from every woman feels changes in their body. The future mother can continue to engage in habitual affairs and work. Soon, nausea may appear, weakness, dizziness, temperature increase and menstruation delay.
Ultrasound during pregnancy at an early term allows you to exclude an ectopic pregnancy, in which, unfortunately, operational surgical intervention is necessary. In this case, the conception occurred in the uterine tube, and not in the uterus. Therefore, the child will not be able to grow normally and develop.
To control the course of pregnancy, putting the necessary analyzes and obtaining consultations of the gynecologist should be registered. In our medical center you will be able to get help of software, starting with the early timelines and until the date of birth.
For such an early term of the future mother, you need to take care of yourself as much as possible, as the embryo is still very weak and vulnerable. Further planned ultrasound will be performed only on the surface of the mother's belly.
The main indicator of the viability of the embryo is its heartbeat. It is this factor that allows you to determine the likelihood of an unfavorable situation for the future child. Each gynecologist pays great attention to the work of the heart of the baby, and therefore carries out control over its rhythm throughout the entire period of pregnancy, as well as during a generic activity.
Pregnancy period from the 3rd to 5th week is considered very important for the development of the fetus. This is due to the fact that it is at that time embryogenesis occurs. The embryo has an appearance of the ear shell, as the letter S.is bent
At this time, specialists during the ultrasound can already consider the root, back, upper and lower extremities.
In the period from 3 to 5 week, the embryo is released by the spinal string (the development of the spinal cord and the spine).
On the correct initiation of the brain may indicate the process of flattening (in a wide end of the embryo) of the nervous tube, which should be passed gradually.
At ultrasound examination, experts can see how the fabric segments called somite are rapidly increasing rapidly increasing, which respond not only for the development of muscles, but also of all tissue structures present in the human body.
This period of gynecologists pay close attention also because the fruit begin to be laid vascular and cardiac systems that develop very quickly.
With the help of a highly sensitive ultrasound apparatus, it is possible to consider the process of forming large blood vessels. They are located in the central part of the embryo and are closely connected with the cluster of the fabric, which at this time is only the prototype of the future heart.
This tangle is a very important substance that takes an active part in the process of organogenesis.
With the successful course of pregnancy, the respiratory tract (upper) will begin to develop from these tissues. In this case, we are talking about trachea and larynx. They also take an active part in the process of laying the pancreas, liver, hosuers (sex cells), which determine the sexual affiliation of the child.
In the period from 3 to 5 week, the pregnancy of gynecologists and the uzists cannot hear the beat of the hearts of the kids (even when using supersensitive equipment), but they confidently claim that embryos already have all the necessary records of vascular and cardiac systems. .
