Prognostic accuracy of cerebroplacental ratio for adverse perinatal outcomes in pregnancies complicated with severe pre-eclampsia; a prospective cohort study

Abstract Objective The current study aims to assess the efficacy of fetal middle cerebral artery/umbilical artery pulsatility index ratio (cerebroplacental ratio CPR) in predicting the occurrence of adverse perinatal outcomes in pregnancies complicated with severe pre-eclampsia. Materials and methods This cohort study included 100 pregnant women between 34 and 40 weeks of gestation attended the labor ward and diagnosed with severe pre-eclampsia. Doppler evaluation was carried out to measure the CPR. Apgar score and fetal umbilical artery pH were assessed within 5 min of delivery. The rate of neonatal intensive care unit (NICU) admission was obtained. Results Apgar score at 5 min >7 was in 82 cases (82%) and 12 cases (12%) scored  7.2 in 67% of cases while 33% of cases had PH Conclusions Adding CPR ratio to routine antepartum fetal surveillance from 34 weeks gestation may help with patient counseling regarding adverse neonatal outcomes for women with severe pre-eclampsia as there is a strong correlation between it and adverse neonatal outcomes.
