Why Fetal Health Monitoring Matters
Regular fetal assessment allows early detection of growth problems, structural abnormalities, and signs of fetal compromise — enabling timely intervention that can make a critical difference to outcomes. In high-risk pregnancies particularly, intensive fetal monitoring is an essential component of safe management.
Fetal Assessment Tools at Petals Clinic
- Anomaly scan (Level II ultrasound) — performed at 18–20 weeks, this detailed scan evaluates all major fetal organ systems, looking for structural abnormalities
- Fetal growth scans — serial scans from 28 weeks to track growth velocity and detect intrauterine growth restriction (IUGR)
- Doppler blood flow studies — assess blood flow through the umbilical artery, middle cerebral artery, and ductus venosus — critical indicators of fetal wellbeing in IUGR and high-risk cases
- Non-stress test (NST) — cardiotocography (CTG) to assess fetal heart rate patterns and detect signs of compromise
- Biophysical profile (BPP) — combines ultrasound assessment and CTG for a comprehensive wellbeing score
- Amniotic fluid assessment — oligohydramnios (too little fluid) and polyhydramnios (too much) are both important findings
NT Scan & First Trimester Screening
The nuchal translucency (NT) scan at 11–13 weeks, combined with blood tests (first trimester combined screening), assesses the risk of chromosomal abnormalities including Down's syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), and Patau syndrome (Trisomy 13). This is a screening test — not a diagnostic one — and results are interpreted carefully in context.
When Is Enhanced Fetal Monitoring Needed?
- High-risk pregnancies — preeclampsia, gestational diabetes, maternal medical conditions
- Multiple pregnancies — twins and higher-order multiples require closer monitoring
- Previous pregnancy loss or preterm birth
- Suspected intrauterine growth restriction
- Reduced fetal movements
- Abnormal amniotic fluid volumes
