Abstract :

Background : Doppler indices form an integral component of noninvasive evaluation of fetal well-being. There is paucity of information about normal obstetric Doppler indices, particularly from the Indian subcontinent. The aim of the study was to find the values of pulsatility index (PI), resistive index (RI) of umbilical artery (UA), and fetal middle cereal artery (MCA) and calculate cereo-placental ratio (CP ratio) for 31–41 weeks of normal gestation. Methods : 250 patients were enrolled in the study for color Doppler study of UA and MCA and were serially followed up at 4–6 weeks interval for Doppler indices. Angle-independent Doppler indices like PI and RI for MCA and UA were obtained during each examination. CP ratio was calculated in each case. All the cases were followed up till delivery and the perinatal outcome was recorded. Results & Conclusion : Abnormal cereoplacental ratio is strongly correlated with IUGR and worse fetal prognosis. Fetuses with abnormal doppler velocimetry have a significantly higher incidence of preterm birth, low birth weight and admission to NICU.Associated risk factors were anemia, PIH, DM, previous history of IUGR, TORCH infection, thyroid disorder. Anemia was found to be common risk factor followed by PIH. In conclusion with the help of non-invasive color Doppler parameters we can identify those pregnancies which are at risk and intervene before the fetus actually become growth restricted and act accordingly for better perinatal outcome.
