OBJECTIVE To evaluate the diagnostic accuracy of the amniotic-umbilical-to-cerebral ratio (AUCR), a new ratio used to predict short-term adverse perinatal outcomes (APO) in pregnant women. METHODS This prospective cross-sectional study was conducted in an obstetrics outpatient clinic to show the sensitivity and specificity of umblico-cerebral ratio (UCR), cerebroplacental ratio (CPR), and AUCR measurements obtained in Doppler ultrasound examinations in pregnant women between 37 0/7 and 41 6/7 weeks of pregnancy in predicting negative intrapartum or postpartum outcomes (fetal distress, Apgar score <7 at 5 min, umbilical arterial pH <7.1, admission to neonatal intensive care unit, and intrauterine death). RESULTS In this study, 260 pregnant women were evaluated, and 49 had negative intrapartum or postpartum outcomes. The UCR value was statistically significantly higher in the group with APO (p<0.001), but the CPR (p=0.001) and AUCR (p<0.001) values were lower. The AUC for CPR, UCR, and AUCR were 0.665 (95% CI: 0.566-0.763), 0.665 (95% CI: 0.566-0.763), and 0.686 (95% CI: 0.592-0.780), respectively. In the multivariate logistic regression analysis of UCR, CPR, and AUCR in the group with APO, there was no statistically significant correlation between CPR, UCR, and AUCR Doppler parameters regarding detecting APO (p>0.05). All patients included in the study gave birth within 24 hours after Doppler ultrasound. CONCLUSION This study found that CPR, UCR, and AUCR could predict APO in term pregnant women. There was no difference in their diagnostic performance.
