When to do a second ultrasound in pregnancy - ultrasound in pregnancy

Any woman is really waiting for the moment when she sees her baby, ultrasound diagnosis allows you to do this a little earlier.

What is ultrasound?

Ultrasound is an echo diagnosis that allows you to see organs in different projections and sections. The principle is based on the emission of waves that either pass through the body or repel, which is precisely what the sensor of the device detects. This signal is further converted into an image that can be seen on the monitor.

It is worth noting that ultrasound has been used in gynecology recently. Although the rays of ultrasound to mankind became known earlier than the X-ray. But already now obstetricians use ultrasound diagnostics for an estimation of a degree of development of the kid. Now ultrasound can objectively diagnose anomalies in development.

Ultrasound during pregnancy

It is accepted to do ultrasound three times. The first study is for 10-12 weeks, the second - for 18-22 weeks, the third - for 32-36 weeks. The order and time of the examination of the woman will tell the gynecologist and her pregnancy card. Therefore, the woman immediately ceases to worry about the next study.

The most important ultrasound

The most important ultrasound for future parents becomes the second in a row. When to do a second ultrasound during pregnancy, a woman will find out when registering. On average, this happens at 18-22 weeks. The second diagnosis allows you to see not just a small lump, but also to distinguish some features of the fetus, since at this time the placenta has not yet fully formed.

What can tell a second ultrasound?

1. At this stage, you can diagnose vivid deviations in development. Almost many organs are developed by this time. Sadly it would sound, but before 24 weeks a woman has the right to have an abortion for medical reasons, that is, if a genetic defect is found. Anomaly of development is confirmed by additional methods of research, which can also refute ultrasound diagnosis.
2. The ultrasound is clearly visible developing placenta, which could not be seen at the first study. A correct evaluation of the placenta is needed in order to protect the child from premature exposure. First of all, the placenta should be developed in accordance with the period, there should not be any excess formations, for example, cysts or calcifications.
3. The second ultrasound will show the condition of the amniotic fluid. They are needed to protect the child from mechanical shocks when the mother turns or tilts. The study will indicate whether the amount of amniotic fluid corresponds to your term. On the basis of the deviation, such diagnoses as: polyhydramnios or hypochlorism may be given.
4. An important test for the study is the size of the fetus. It is the size that can tell about pathological development. With each ultrasound, the doctor measures the parameters and assesses the dynamics of growth.
5. And perhaps the most important thing you can learn on the second ultrasound is the sex of the child. Perhaps, Mom already knows it, if the first ultrasound was carried out at the end of the first trimester. But the second ultrasound will help to confirm the sex exactly. True, there are also cases when the baby is in such a position, which does not allow to say about his sexual development. In this case, you do not need to be upset, just get the things of the neutral color given to the child.

There are times when you can do a second ultrasound in pregnancy before 20 weeks. This can be facilitated by an analysis of HCG that does not match the timing of pregnancy, or the age of the future mother. Therefore, it is very important, as soon as possible to identify violations and adjust them so that the baby can be born healthy.

Harmful ultrasound

Today, experts can not come to the opinion - it's dangerous if you do not have an ultrasound, especially at the time of 9-10 weeks, when the main organs and systems are laid. The doctor has the right to prescribe and early ultrasound if there is an assumption of abnormal development or threat of miscarriage.

3D-

Now in most clinics that provide services to pregnant women, there are devices that allow you to create a three-dimensional picture. That is, instead of the usual rays - parallel - through the fruit rays pass at different angles, which create a three-dimensional image. Also, we can say that there is a service that allows you to see not only the baby in volume, but also his movements in real time. For this, an additional monitor is installed in front of the woman, on which the baby is visible. Such a study can be recorded on a CD disc.

Many women distrustful of this procedure, explaining this by the fact that the child turns away with ultrasound. This may be due to the posture of the child, as well as the pressure of the sensor, which leads to the stomach. It is also worth noting that every year brings something new to this technology, harm becomes minimal, and information is more objective.
