title: The Value of the Cerebroplacental Ratio for the Prediction of Intrapartum Fetal Monitoring in Low-Risk Term Pregnancies.
abstract: OBJECTIVE
  The study aimed to investigate the use of fetal cerebroplacental ratio (CPR) to identify fetuses at high risk before labor due to the brain sparing phenomenon.
  
  
  METHODS
  Four hundred and seventy-six singleton pregnancies were enrolled in this study. The CPR was recorded within 1 week of delivery and labor was managed according to local protocols and guidelines. Intrapartum and neonatal outcome details were recorded.
  
  
  RESULTS
  The CPR values of fetuses subsequently presenting category III intrapartum electronic fetal monitoring (EFM) or category II EFM without improvement (category IIB EFM) or with progression to category III (category IIC EFM) were significantly lower. On multivariate logistic regression, CPR was independently associated with the risk of categories III EFM, IIB EFM and IIC EFM. CPR was also a predictor of categories III EFM, IIB EFM and IIC EFM.
  
  
  CONCLUSIONS
  Fetal CPR could be used to identify fetuses at high risk before labor and to help guide intrapartum management decisions.
