Role of fetal Doppler cerebroplacental ratio in the surveillance of late term pregnancies

Abstract

The present study aimed to assess the value of fetal Doppler cerebroplacental ratio (CPR) measurement in the surveillance of late term pregnancies to determine correlation of CPR with incidence of thick meconium stained liquor. Subjects And Methods: This was cross sectional study, started with 72 pregnant women, 4 of them dropped out and 68 of those participants were included in this study and admitted to Ain Shams university Maternity Hospital, during the period from December 2018 till May 2019. Results: results of the study revealed that MCA PI and CPR had significant high diagnostic performance in predicting thick meconium; higher in MCA PI. UA PI had no significant diagnostic performance in predicting thick meconium. MCA PI and CPR had significant moderate diagnostic performance in predicting NICU requirement; higher in MCA PI. UA PI had no significant diagnostic performance in predicting NICU requirement. Conclusion: MCA PI ≤1.06 and CPR ≤1.32 had a significant high diagnostic performance in predicting thick meconium; higher in MCA PI. UA PI had no significant diagnostic performance in predicting thick meconium. MCA PI ≤ 1.10 and CPR ≤ 1.39 had a significant moderate diagnostic performance in predicting NICU requirement; higher in MCA PI. UA PI had no significant diagnostic performance in predicting NICU requirement.
