Schmidt // Obstetrics & Gynecology Science. – 2019. – Vol. 62, N 6. – P. 469–473. – DOI: 10.5468/ogs.2019.62.6.469.https://repo.knmu.edu.ua/handle/123456789/31905Fetal growth restriction (FGR) is characterized by fetal compromise and delayed neurological maturation. We report 3 cases of early FGR in the 26th week of gestation, based on hemodynamic Doppler monitoring, conventional cardiotocography, and non-invasive fetal electrocardiography (NI-FECG). Fetal heart rate variability (HRV), beat-to-beat variations, and fetal autonomic brain age scores (fABASs) were normal despite the absence of umbilical diastolic flow in the first case and the pregnancy continued to 30 weeks. NI-FECG helped achieve better fetal maturity. Fetal HRV and fABASs were low in the second and third cases. Fetal demise occurred soon in both cases. We conclude that NI-FECG could be a prospective method for the detection of fetal distress in early FGR.enfetal distressfetal growth restrictionembryonic and fetal developmentArticle
