Pruksanusak N, et al. - The predictive ability for identification of peripartum asphyxia neonates by utilizing the 3-tier and 5-tier fetal heart rate (FHR) classification systems was improved in this study. It was concluded that the maternal-associated risk factors combined with an abnormal 5-tier FHR classification had high predictive ability and specificity to detect peripartum asphyxia neonates.
