What is NST?

It is one of the tests frequently heard by couples during pregnancy and performed several times during their pregnancy. Our aim is to give information about this test, especially in the last stages of pregnancy, without going into details.

NST (non-stress test) is one of the indispensable tools of today’s medicine, where we have an idea about the general condition of the baby that continues its development in the uterus during the last stages of pregnancy and in problematic pregnancies. Two probes with the ability to show the baby’s heartbeat and uterine contractions are attached to the abdominal region of the pregnant woman to be nst. The warnings received from these probes for an average of 20 minutes are processed on the printer part of the device and the result is evaluated by the obstetrician.

The probe placed for the baby’s heartbeat allows us to have information about the baby’s heartbeat through sound waves. With the evaluation made on the printout on the paper, it is possible to comment on whether the baby is in good or bad condition in the mother’s womb. The probe, which reveals the presence of uterine contractions, gives an idea about the threat of preterm labor and the onset of labor.

NST is an indispensable tool for the follow-up of pregnant women who have problems during their pregnancy. However, it should not be forgotten that nst is only one of the tests performed in pregnancy follow-up and should not be used alone when deciding on the outcome of pregnancy. Nst is one of the auxiliary tools used in pregnancy follow-up. Its use has no adverse effects on the developing baby and mother.

Who should NST be done?

All pregnant women after 40 weeks of gestation
• If the pregnant has a systemic disease such as blood pressure, diabetes, rheumatological disease
• If you have gestational blood pressure or gestational diabetes.

• If the baby is small for the gestational week or its development is slow

• If there is a decrease in the baby’s movements

• If the baby has a decrease in water.

• If there is a history of baby loss in a previous pregnancy

How is NST applied?
If your doctor hasn’t said anything else before taking the NST, you should definitely be full. As it is known, there is a decrease in the baby’s movements when you are hungry, which leads to misinterpretation of the NST. It is recommended to go to the toilet before connecting the NST; sometimes this test can take up to 1 hour.
During NST, it is necessary to lie on the left side as a position. Two probes capable of showing the baby’s heartbeat and uterine contractions are applied to the abdominal region of the pregnant woman to be NST, and tied with belt-like adhesive tapes. The warnings received from these probes for an average of 20 minutes are processed on the printer part of the device and the result is evaluated by the obstetrician.

If the baby is not moving, the baby may be asleep, in this case, maneuvers such as gently pressing the abdomen, shaking the abdomen can be done to wake the baby from sleep, and drinking a sugary liquid can also stimulate the baby.

How should test results be evaluated?

In order for us to say normal NST (reactive NST), there must be an increase in heart rate of 15 beats for at least 15 seconds 2 times during the 20-minute scan during the baby’s movements.

In NST, the baby’s heart rate should normally be between 120-160 beats per minute; The fact that the baby’s heartbeat is outside these values, that is, faster or slower, indicates that the baby is in distress in the womb, that is, its oxygenation has begun to decrease.

NST is one of the auxiliary tools used in pregnancy follow-up. Its use has no adverse effects on the developing baby and mother. However, like any test, there are false positives and negatives. In other words, the test may be bad even though the baby is good, or on the contrary, the test result can be interpreted as good even though the baby is bad.

CONCLUSION:
– NST is a test used for the evaluation of risky pregnant women (conditions such as growth retardation in the baby, decreased water level, high blood pressure or sugar in the mother).
– Unnecessary NST may cause unnecessary interventions, including premature delivery of the pregnant woman.
– In a pregnant woman whose everything is normal, NST should be performed only when her doctor deems it necessary or after the day is up.
