Objective To predict intrapartum fetal compromise (FC) and admission to neonatal intensive care unit (NICU) by cerebroplacental ratio (CPR) in term pregnancies. Methods A prospective observational study recruited women with singleton, term pregnancies. Ultrasound (US) was done for fetal biometry, umbilical and middle cerebral artery (UA, MCA) Doppler parameters, and CPR calculated. Intrapartum variables and neonatal data were recorded. Results Mean interval from US to delivery was 2.21 ± 2.71 days. Rate of operative delivery for FC was 17.47%. Multivariate logistic regression analysis showed that UA pulsatility index (PI) multiples of median (MoM) ( P = 0.001), MCA PI MoM ( P = 0.001), and CPR MoM ( P = 0.001) were significantly and independently associated with operative delivery for FC. Similarly, UA PI MoM ( P = 0.004), MCA PI MoM ( P = 0.009), and CPR MoM ( P = 0.003) were also significantly and independently associated with admission to the NICU. Rate of operative delivery for presumed FC was higher in approprate‐for‐gestational‐age fetuses with low CPR than in small‐for‐gestational‐age fetuses with normal CPR (43.1% and 37.5%, respectively). Conclusion Lower mean CPR and CPR MoM were independently associated with the need for operative delivery for presumed FC and NICU admission at term. CPR is more likely to be associated with FC due to placental insufficiency than birth weight.
