qCTG and Doppler Ultrasound in the Detection of Hypoxia Among FGR Fetuses

Quantitative Cardiotocography and Doppler Ultrasound in the Detection of Hypoxia Among Growth-restricted Fetuses

To evaluate the benefits of combining Doppler measurements of placental/fetal blood vessels with computerized cardiotocography (quantitative cardiotocogrpahy - qCTG) in the detection of fetal hypoxia (pH < 7.20) among late-onset growth restricted (SGR) fetuses

• full follow-up documentation

Exclusion Criteria:

• multiple pregnancies;
• congenital malformations and any chromosomal malformations known before labor and delivery;
