Cervicometry during pregnancy - as do and norms

Cervicometry during pregnancy - as do and norms

Briefly about the procedure of cervicometry

This is the name of ultrasound, which allows you to determine the length of the cervix, and also assess the condition of the canal, internal and external throat. Usually, obstetrician-gynecologists appoint this study to their patients in order to assess the possible risk of preterm labor and, if pathology is found, avoid complications. If there are deviations from the norm, then specialists have the opportunity to take timely measures to allow a pregnant woman to take the child to the required time without special problems.

The procedure for cervicometry is carried out from 12 to 22 weeks. If a woman has a premature birth in the past or a multiple pregnancy is detected, such manipulation is done for up to 15 weeks and for safety - at week 20.

The result of this study depends on a number of factors affecting the length of the cervix and the general condition of the female's internal organs. If she gave birth, then the norms of cervicometry will differ from the norms of the primiparous lady. They also depend on the gestational age at which cervical ultrasound is performed. It is done with a transvaginal sensor. It is a special tube. Such a study should be done after emptying the bladder, because its fullness also affects the accuracy of the result.

You should know that cervical ultrasound alone does not harm the unborn child, and for the woman is completely painless. So do not worry about this appointment. After all, it allows you to eliminate the risk of complications and termination of pregnancy.

To whom the procedure is assigned

Cervicitometry during pregnancy is performed under such conditions and indications:

  1. In case of multiple pregnancy.
  2. If a woman before the onset of pregnancy has undergone surgery on the genitals.
  3. With a short cervix.
  4. If there is an ischemic-cervical insufficiency.

So, when the supervising obstetrician-gynecologist directs the pregnant woman to such a study, then you can not refuse it.

Cervicometry norms

The cervix after conception changes its shape. This allows doctors to assess what will be the beginning of labor. When the data of cervical ultrasound are normal, there is no cause for worry for the expectant mother. His indicators vary on different terms of bearing a child. It depends on the increase in the mass of the future baby. So, for a period of 16 to 20 weeks, the length of the cervical canal is normally 40-45 millimeters; at week 24 - about 37 mm, at 25-28 weeks - 35-40, at 32-36 week of the term - from 30 to 35 mm. If this body is shorter than the above indicators, the birth may occur earlier than the deadline. And the smaller the length of the cervical canal, the risk of premature birth is higher. So, ultrasound examination of the cervical canal obstetrician-gynecologists appoint many future mothers. Such a diagnostic procedure allows doctors to eliminate the risk of complications of pregnancy, to take the necessary measures to preserve it. In case of premature opening of the cervical canal, the observing obstetrician-gynecologist prescribes medication for keeping him closed until the birth.

Identification of possible complications of pregnancy is an important aspect of a fully-fledged baby. Therefore, you should not give up cervicometry if it is recommended by your doctor.
