On what terms do ultrasound in pregnancy. How many times do ultrasound

In the period of expectation of the baby, the representative of the weaker sex will have to undergo numerous studies and take a lot of tests. So, before each reception at the doctor-gynecologist the future mum should hand over a blood and urine for research. The results obtained make it possible to judge the course of pregnancy and the state of health of a woman. In this article, we will talk about the timing of ultrasound in pregnancy. You will find out the specifics of conducting this diagnosis. Also you will be able to find out the generally accepted terms of ultrasound in pregnancy.

Ultrasound diagnostics

This type of research has been used for a long time. Every year there is an improvement in inspection methods. So, in modern medical clinics you can not only undergo the usual ultrasound, but also make a study in several planes (3D and 4D).

Ultrasound diagnosis is carried out as follows. During the examination, the doctor applies a special sensor to the body of the patient sending the impulses. This ultrasound is reflected from the organs and displays an image on the screen. The patient and the doctor can not hear the ultrasound, that's how it has very high frequencies.

It should be noted that the study can be conducted in several ways. At the earliest time of embryo development, a transvaginal sensor is selected. The doctor applies a special conductive gel on it and inserts it into the vagina. Later pregnancy allows for a transabdominal ultrasound. This selects a slightly different sensor, which is applied to the abdomen of the future mother.

How many times do ultrasound during pregnancy and before its onset?

If a woman is just planning to conceive, the doctor will give her a course of examinations called folliculometry. This method allows you to track the growth of the follicle and as accurately as possible determine the time of release from the egg. Thanks to this method, the probability of conception increases several times. During folliculometry, a woman is given one to three ultrasound examinations.

With the onset of pregnancy, the expectant mother should visit the ultrasound room as prescribed by the doctor. How many times do ultrasound in this case? In normal pregnancy, the study is conducted no more than three or four times for the entire period. However, in half the cases, women are forced to undergo this procedure more often.

Establishment of the fact of pregnancy: on what date?

When can you safely go for ultrasound to determine the fetal egg in the uterine cavity? On what terms do ultrasound in pregnancy in this case?

It is possible to establish the conception that has taken place starting from the fifth week of pregnancy. In this case, you can not see the embryo. However, an experienced specialist will discover the formation in the uterine cavity, which will later become your child. At earlier times there is a possibility of error, since some devices can not recognize such a small point (in this period the size of the fetal egg is not more than two millimeters).

On what terms do ultrasound in pregnancy?

In fact, there is no clearly established, generally accepted time for diagnosis. Everything depends on the number of fetuses, the course of pregnancy, the health and age of the expectant mother. If everything goes smoothly, the timing of the diagnosis will be separately set for the first, second and third trimester.

First ultrasound

At what time does this study? Doctors recommend diagnosing at 11-14 weeks. Such a survey allows you to determine the time period as precisely as possible. On ultrasound it is much easier to do than during a gynecological examination. Diagnosis is most often performed by a transvaginal device, since the uterine cavity is still in the pelvic area. However, with modern equipment, a specialist can choose a transabdominal method for research.

Also, the study can report the number of fetuses in the cavity of the childbearing organ. During this period, the child's place, its location and the presence of detachments must be inspected. At this time, it is possible to identify possible deviations in embryo development. The size of the future child is not so small and the basic formed organs are quite clearly visible.

Second ultrasound study

2 ultrasound term has the following: from 20 to 22 weeks of embryo development. At this stage, the doctor can already use a transabdominal device. Specialist greases the belly of the future mother with a gel and applies a device to it.

This diagnosis allows you to examine in detail the uterine cavity and note the condition of the fetus. The kid by this time has already reached sufficient size, and the doctor can count his fingers. Also, the internal organs of the baby and his face are inspected. The doctor determines the location and age of the placenta, it is necessary to examine the blood flow, which is installed in the umbilical cord.

Third ultrasound study

3 ultrasound term usually has the following: from 32 to 35 weeks of embryo development. With this diagnosis, a transabdominal sensor is always used. This research is usually the last. This is why the specialist draws attention to details that are very important during labor.

So, the doctor marks, what term defines US for the beginning of sorts or labors. In most cases, the height and weight of the baby are taken into account. Also, the doctor looks at the presentation of the embryo and the location of the placenta. It is worth noting that in some cases the body can migrate. Be sure to examine the umbilical cord and its position. If there is an accent, then this should be taken into account.

A study with suspicion of ectopic pregnancy: on what date?

Sometimes circumstances develop so that the embryo begins to develop outside the cavity of the genital organ. In this case, most often there is a tubal pregnancy. Symptoms of such pathology can be pain and spotting. To accurately diagnose, a woman is sent for ultrasound. In this case, the diagnosis period will be in the range of four to eight weeks of pregnancy.

The transvaginal sensor is being examined. During the procedure, the doctor determines the location of the embryo and its age. When a pathology is detected, an immediate correction is made.

Diagnosis of the threat of interruption of embryo development

If it is a question of a beginning or threatening abortion, the diagnosis is carried out immediately. At the same time, the age of the embryo is completely unimportant. Such a pathology can occur at 6 and 20 weeks. It is worth noting that most often a woman is sent to inpatient treatment. It is within the walls of the medical institution that diagnostic manipulation is performed. If there are certain problems, then a corresponding correction is assigned. After it, repeated diagnostics with an ultrasound device is performed.

In what cases is additional research required?

On what terms do ultrasound in pregnancy in case of need for additional diagnosis? Everything depends on the individual anamnesis of each woman.

• If previously the representative of the weaker sex had miscarriages or premature birth due to iscico-cervical insufficiency, the study is conducted at 10, 14 and 16 weeks to monitor the cervix.
• At previous births by cesarean section, diagnosis is performed at 30, 35 and 37 weeks of pregnancy. This is necessary to control the condition of the scar.
• In a multiple pregnancy, ultrasound may be administered at 34 and 36 weeks of embryo development. Such a study shows the location of the babies and their parameters. It is worth noting that twins and triplets are born usually a few weeks before the due date.
• If a woman suffered a viral or bacterial disease that was accompanied by a rise in body temperature or complications, it is worthwhile to perform an unscheduled ultrasound. Such a diagnosis can show whether the pathology has affected the fetus and its development.
• It is necessary to have an unscheduled ultrasound if the expectant mother has ceased to feel the fetus moving. It can talk about acute hypoxia or death of an embryo.

In what terms are ultrasound performed, if a woman does not know the date of the last menstruation?

Surely everyone knows that gestational age is established by gynecologists on the first day of the last month. However, it is not always possible to calculate this date. If a woman has severe disruptions in the cycle or she is breastfeeding, then in what time should ultrasound be performed?

Once a woman has a positive test result for pregnancy, the doctor sends her to the examination. In this case, what time period - shows ultrasound. Proceeding from this, the subsequent dates for carrying out diagnostic manipulations are calculated.

How many times is it possible to do ultrasound

On this issue there are still disputes, and there is no consensus. Some doctors believe that such studies are completely safe and can be carried out at least every week. Other doctors are of the opinion that such additional manipulations should be avoided. How to be a woman?

All future mothers are advised to listen to the advice of a gynecologist. If there is evidence, it is worthwhile, without hesitation, to conduct a study. In some cases, timely diagnosis can save the life of your baby.
