CTG fetus

In the second half of pregnancy the number of tests increases. To him all of a sudden added another view: CTG of a fetus. During the first pregnancy the expectant mother is frightened: it means that with the child something not so?

Cute moms, you should know that CTG of the fetus, usually no more than a routine check of the habits of the muscles of the uterus and the heart of the unborn baby. CTG – Cardiotocography, the procedure is absolutely painless and completely harmless.

All women in the second half of pregnancy, after 26 weeks, administered at least twice passage cardiotocography. As a rule, this examination is written in advance and come at the appointed hour.

This Procedure is – not fast. To gather enough objective information about the uterine contractions and cardiac activity of the fetus, it is necessary from 40 to 60 minutes. The woman or placed on a comfortable couch or seated in a comfortable recliner, and a measurement of CTG fetus begins: on her stomach is attached to a sensor that transmits information to the electronic unit, the reflection information is recorded on a special tape.

Dear ladies, do not torture issues lab, she's in all these numbers and lines skills are much better than you. The real issue the test results can only a doctor, after a complete decoding data.

When checking the CTG fetus decoding assesses a number of indicators of its state:

1. The basal rhythm (otherwise it is called heart rate-heart rate). Fetal heart rate more than the already born child. According to CTG of a fetus, at rest, the heart rate of the baby varies in the range from 100 to 160 beats per minute, with the stirring – 190.

2. Variability (i.e., individual deviations from the norm) may be up to 25 beats per minute.

3. Acceleration of heart rate (acceleration), as a rule, it happens more than 2 times in 10 minutes. How much more-depends on the individual characteristics of the future baby. On the ribbon, displays the high "peaks"

4. Slowing of heart rate (decelerate) may be absent altogether or has low rates (small "holes).

5. Tomogrammu – uterine activity. It normally takes no more than 15% of the increased heart rate, duration – above thirty seconds.

On a scale evaluated each indicator – and the doctor in charge of the development of the fetus, reported totals.

If the sum of the figures from 9 to 12 points, you can safely go for a walk: no reason for alarm. But this does not mean that repeated invitations to the survey can be dismissed – vigilance never hurt anyone, just now you can not worry: you have everything in order!

If the doctor reports that the amount of points in the CTG fetus – 6 to 8 points means that the fetus is not getting enough oxygen, there is a dimly severe hypoxia (not threatening). This may be due to maternal illness, suffocation of the baby by the umbilical cord, sometimes the first analysis simply in virtue of some reasons is inaccurate. A woman is sent for re-analysis.

And only in case if the total figure is 5 or less – this means a pronounced oxygen starvation of the fetus. In this case, offer an emergency delivery to the cerebral cortex of the fetus was not injured.

But what is ACTH the norm? Why to determine if it is necessary to take a blood test? This is a test, nothing to do with CTG fetus. ACTH regulation determines the number corticotropic hormones in the blood. The upper limit of normal-to 69 pmol/liter, lower – 7.2 pmol/liter. This hormone prepares the uterus for childbirth, reduces the level of the generic stress involved in the process "launch" of the mechanism of delivery. It counted on the presence in the blood plasma. The analysis is done once.

Cute mom, if the doctor gives direction - it's not a reason for alarm. Try to stay calm, everything will be fine.
