Twenty-six term newborns with intrapartum fetal asphyxia, determined biochemically (umbilical artery base deficit > 12 mmol/l), were compared with 59 normal newborns to determine the effect of intrapartum fetal asphyxia on newborn blood pressure and cerebral blood flow velocity following delivery. Cerebral blood flow velocity observations with concurrent measures of blood pressure and heart rate were obtained during the 24 h after delivery and after 24 h. After delivery, diastolic blood pressure in the newborns of the asphyxia group was significantly greater than that of the newborns of the normal group and this difference persisted after 24 h. Cerebral blood flow velocity in the newborns of the asphyxia group was of the same order as that of the newborns of the normal group during the 24 h after delivery. However, there was a significant increase in both peak systolic and end-diastolic blood flow velocity after 24 h. The duration of metabolic acidosis may be a factor in the occurrence of this delayed cerebral blood flow velocity response. Observations of cerebral blood flow velocity should be continued for more than 24 h following delivery to determine the effect of intrapartum fetal asphyxia.
