In the second half of pregnancy the numberanalyzes and surveys is increasing. To them suddenly another species is added: CTG of the fetus. At the first pregnancy, the expectant mother is frightened: does it mean that something is wrong with the child?
Lovely future moms, you should know that CTG fetus is usually no more than a routine check of how the uterus muscles behave and how the heart beats the future baby. KTG is cardiotography, the procedure is absolutely painless and completely harmless.
All women in the second half of pregnancy,after the 26th week, at least twice the cardiovascular path is prescribed. As a rule, these examinations are recorded in advance and come at a fixed hour.
This procedure is not fast.To collect fairly objective information about uterine contractions and fetal heart activity, it takes from 40 to 60 minutes. A woman is either laid on a comfortable couch, or seated in a comfortable deep chair, and the CTG measurement of the fetus begins: a special sensor is attached to her abdomen, which transmits information to the electronic unit, the information reflected is fixed on a special tape.
Dear women, do not torment the lab assistant,it is not much better than you in all these figures and lines. Actually, only the doctor can give out the results of the check, after full decoding of the data.
When testing the CTG of the fetus, decoding evaluates a number of indicators of its condition:
1.Basal rhythm (otherwise it is called heart rate - heart rate). The fetus has a pulse more often than the already born child. According to the CTG of the fetus, at rest the pulse of the baby fluctuates in the range from 100 to 160 beats per minute, while stirring - up to 190.
2. The variability (that is, individual deviations from the norm) can reach 25 beats per minute.
3.Acceleration of the heart rate (it is also an acceleration), as a rule, happens more than 2 times in 10 minutes. How much more depends on the individual characteristics of the baby's future. The tape shows high "peaks"
4. Deceleration of heart rate (desereration) may be completely absent or has low indicators (small "pits").
5. Togogram - uterine activity. It is normally not more than 15% of the heart rate, the duration is more than thirty seconds.
On a special scale, each indicator is evaluated - and the doctor responsible for the development of the fetus is informed of the final indicators.
If the sum of the indicators is from 9 to 12 points, youyou can safely go for a walk: there is no reason for alarm. But this does not mean that you can dismiss the repeated invitation to the examination - vigilance has not prevented anyone, just now you can not worry: you are doing fine!
If the doctor reports that the sum of scores on the basis ofCTG of the fetus - from 6 to 8 points, which means that the fetus does not receive enough oxygen, there is a pronounced hypoxia (not threatening). This may be the result of a mother's illness, the cord of the baby with the umbilical cord, sometimes the first analysis is simply inaccurate for some reason. The woman is sent for reanalysis.
And only if the overall indicatoris 5 or less - this means pronounced oxygen starvation of the fetus. In this case, an emergency delivery is suggested so that the fetal cortex is not affected.
And what is ACTH norm?Why is it necessary to give blood for analysis to determine it? This is a test that has nothing in common with the CTG of the fetus. The ACTH norm determines the amount of corticotropic hormones in the blood. The upper limit of the norm is up to 69 pmol / liter, the lower limit is 7.2 pmol / liter. This hormone prepares the uterus for childbirth, reduces the level of birth stress, participates in the process of "starting" the mechanism of childbirth. It is counted by the presence of blood plasma. The analysis is done once.
Lovely mom, if the doctor gives direction - this is not a reason for anxiety. Try to stay calm, everything will be fine with you.
