What is NST?
NST testing does not cause any stress for the baby and the NST test is performed in all pregnant women with over 28 weeks. However, nst testing is not an ordinary test in normal pregnancy cases. This test is only applied to the pregnant woman in some cases of pregnancy. In other words, not every pregnant woman has to be tested for this.
How to Take an NST Test?
In this test, a belt is thrown over the mother’s abdomen and 2 devices are attached to this belt. These devices are linked to the heart rate of the baby in the womb and to examine the uterine contractions. These devices should help the mother to mark the movements of the baby in the womb after being pinned to the belly with a belt. So every time the baby moves, the mother pushes the button to determine. The average duration of the NST test is between 20 and 30 minutes. In order for this test to result in a positive outcome, the heart rate of the baby in the womb should be observed properly.
To explain this situation, we can say that the baby in the womb should show the heart acceleration, which lasts 2 times and 10 seconds during the observation period of at least 20 minutes. During this time, if the infant has a heart rate of at least 2 times, this test does not need to be performed for a longer period of time. If this occurs as described, the baby will be safe in the womb and will be finalized for at least 1 week.
What Does NST Show?
The purpose of this test is to determine if there is a placental problem. In the case of some cases, the placenta cannot adequately perform its functions and therefore the life of the baby in the womb is at risk. In such a case, the only way to save the baby is to give birth prematurely.
Cases Requiring NST
• If the normal date of birth has passed and the birth has not taken place.
• If the baby in the womb has noticed a decrease in movements.
• If the mother has diabetes problem.
• If the mother has hypertension.
• If the growth rate of the baby in the womb is below normal.
Is There any risk in performing the NTS Test?
There is no risk to the mother or the baby in the womb in this test.
When is the NST Test performed?
In order to perform this test, the pregnant woman must be at least 28 weeks. Because in earlier pregnancies, the movements of the baby in the womb cannot be monitored clearly enough, such as the movements of the 28-week-old baby.
What exactly is looked at in the NST Test?
This test is the reaction of the heart rate of the baby moving in the womb to these movements. When a healthy baby moves in the womb, the heart rate accelerates and the heart rate slows when it does not move. The main idea under this test is that the baby should have enough oxygen in the womb in order for the baby to be sheltered and moved in a healthy way in the womb and the rate of heart beat in the baby is normal. If there is not enough oxygen in the womb, neither the baby’s movements nor the infant heart rate are normal. Declining oxygen levels is also usually a problem in the placenta.
What Do NST Results Mean?
In other words, the positive test result means that the heart rate accelerates accordingly as the baby moves in the womb. The negative result is also the fact that “Non-reactive NTS”, as well as the baby’s movements in the womb, cannot observe any increase in heart rate. In such a case, it is foreseen that the baby in the womb does not receive sufficient oxygen and further tests are performed for both mother and baby health.
Non-reactive NTS may also be caused by the baby’s sleep in the womb or some medications used by the mother. Another test requested when non-reactive NTS is observed is cst test. CST is a stress test due to contraction, i.e. Turkish. In this test, the mother is given medication and the uterus is forced to contract artificially. These artificial uterine contractions cause stress in the baby and the heart rate in the stress-ending baby is observed. If the baby’s heart rate is adversely affected by this situation, then the decision is made to intervene immediately.
