Contraction Stress Test (CST) During Pregnancy and Its Implications for Fetal Health

If Positive Test Contraction test

would be abnormal, not good, it means babies HR dropped with contraction and delivery of baby C-Section

The Contraction Stress Test (CST), also known as the oxytocin challenge test, is a prenatal test to evaluate the fetal heart rate in response to uterine contractions. If the result of a Contraction Stress Test is positive, it indicates an increased risk of fetal distress, which may require immediate intervention to prevent fetal hypoxia or birth complications.

If a mother’s CST result is positive, it means that the baby’s heart rate decreased during the contractions, which is not a good sign. The possible causes of decreasing fetal heart rate can be due to insufficient oxygen supply to the baby, and the baby’s body is trying to conserve oxygen. The mother’s health condition factors such as low blood pressure, lack of nutrients, or lack of oxygen can put the baby at risk of fetal distress.

When the CST result is positive, the doctor will recommend follow-up tests to confirm the baby’s condition. These follow-up tests include:

1. Biophysical Profile (BPP) – a non-invasive prenatal test used to evaluate the baby’s overall condition, including amniotic fluid level, fetal breathing, fetal movement, fetal tone, and fetal heart rate.

2. Non-Stress Test (NST) – measures the fetal heart rate response to the movement of the baby using fetal monitoring.

3. Doppler Ultrasound– measures the blood flow in the umbilical cord, placenta, and fetal vital organs.

In conclusion, a positive Contraction Stress Test result means an increased risk of fetal distress and requires further medical attention. It is essential to follow medical advice and have regular prenatal visits to ensure the health and safety of the mother and the baby.
