Comparison of fetal Doppler blood flow characteristics of late-term and post-term pregnancies

Abstract

Aim: The aim of this study was to compare fetal Doppler flow characteristics in uncomplicated late-term and post-term pregnancies over 41 weeks and to evaluate their effect on postpartum outcomes. Materials and Methods: A total of 98 late-term and post-term singleton pregnant women in the low risk group who were admitted to the Umraniye Education and Research Hospital Obstetrics and Gynecology Polyclinic were included in the study group. The gestational week of all pregnant women was calculated by confirming their last menstrual period and early period ultrasonography data. Estimated fetal weight, amniotic fluid index, biophysical profile and Doppler examinations (fetal umbilical artery, middle cerebral artery and maternal uterine artery) were performed by sonographic evaluation. The pulsatility and resistance indices of the middle cerebral and umbilical arteries and cerebroplacental ratio were evaluated daily by Doppler ultrasonography. Delivery type, birth weight, amniotic fluid with meconium at birth, presence of fetal distress finding in NST, 5th minute Apgar score, cord blood pH value in presence of fetal distress and neonatal intensive care requirement of newborns were recorded. Results: There was no difference between the mean values of uterine artery pulsatility index, umbilical artery pulsatility index and middle cerebral artery resistance index in both groups. In the post-term group, the mean umbilical artery resistance index and middle cerebral artery pulsatility index values were significantly lower. Although cerebroplacental ratio was lower in the late term group, this difference was not statistically significant. In both groups, no significant difference was found between the rate of hospitalization in the intensive care unit of newborns. Conclusion: Although there is no significant relationship between abnormal and normal cerebroplacental ratio results in terms of the well-being of the newborn and need for hospitalization in the intensive care unit, larger series of study groups are needed.
