Contraction Stress Test (CST): A Prenatal Test to Monitor Fetal Health

Contraction Stress Test (CST)

See how baby will reacts to contraction, and can the baby handle one, if not there will be a scheduled C-Section. Mom will stimulate 1 nipple for 2 minutes until a contraction of 10 min fetal HR should remain stable and not drop.

The Contraction Stress Test (CST) is a type of prenatal test used to monitor the health of the fetus during the third trimester of pregnancy. It is also known as the oxytocin challenge test. The test evaluates the response of the fetal heart rate (FHR) to contractions of the uterus, which provides information about the baby’s oxygen supply.

During a CST, the mother’s uterus is stimulated to contract either by administering intravenous oxytocin or by stimulating the nipples. The FHR is monitored before, during, and after contractions. The test usually lasts for at least 40 minutes and requires the mother to lie on her back while the contractions are monitored.

If the baby’s heart rate remains steady during the contractions, it indicates that the baby is getting enough oxygen and is in good health. However, if the baby’s heart rate slows down or decelerates during the contractions, it suggests that the baby is not receiving enough oxygen. This could indicate fetal distress and might require further medical attention.

CST is generally recommended for women who have high-risk pregnancies, such as those with a history of preterm labor, gestational diabetes, or hypertension. It can also be used to assess the baby’s well-being if the mother has a medical condition that affects fetal health.

In summary, the Contraction Stress Test is a prenatal test that provides valuable information about the fetal heart rate and oxygen supply during uterine contractions. This is an important test that can help identify potential problems in the baby’s health and ensure appropriate medical intervention.
