Is perinatal hypoxia assessed by the combination of clinical and biochemical measures (Apgar score and umbilical cord blood pH) associated with cerebral palsy?In this cohort study of 825 159 singleton newborns (≥35 gestational weeks), the combination of low Apgar score and low umbilical cord blood pH was associated with an increased risk of cerebral palsy, substantially higher than when 1 measure was abnormal.This study found that cerebral palsy risk was highest when both clinical and biochemical measures were abnormal.
