Correlation between Doppler Indices as A Predictor of Neonatal Outcome in Normal and Preeclamptic Pregnant Women in The Third Trimester

Abstract

Background: Doppler flow velocimetry of the umbilical artery and cerebral circulation is a non-invasive modality used for assessment of fetal wellbeing. Doppler studies are more specific and are potentially useful tool in prediction of adverse perinatal outcome in high risk patients. Aim of the current study was to evaluate the efficacy of middle cerebral artery pulsatility index (MCA-PI), umbilical artery pulsatility index (UA-PI), uterine artery pulsatility index (UAT-PI), and a cerebroplacental ratio (CPR) Doppler indices in assessment of fetal wellbeing. For documentation of the neonatal outcome in preeclamptic women with abnormalities of Doppler indices. Objectives: Assessment of fetal wellbeing and prediction of neonatal outcome in normal pregnant women and woman with preeclampsia by using Doppler indices. Patients and Methods: the study isacase control study included 94 pregnant women (47 normal pregnancy and 47 preeclamptic patients) admitted in Obstetrics and Gynecology Department of Menoufia University during the period from August 2018 to November 2019. All included women underwent Doppler study and were followed up till delivery. Results: Doppler velocimetry studies of both placental and fetal circulation can provide important information as regard fetal wellbeing so can be used to improve fetal outcome. Conclusions: It was observed that all three parameters UAT-PI, MCA-PI and UA-PI when taken into consideration together are good parameters in predictions of perinatal outcome.
