Nucleated red blood cells: a marker for fetal asphyxia?
Article Abstract:
The nucleated red blood cell count may indicate whether a fetus has experienced a lack of oxygen, and may predict whether a newborn will experience neurologic impairment throughout its life. Researchers compared nucleated red blood cell counts from 46 newborns with neurologic impairment to those of 83 normal newborns who did not experience a lack of oxygen. Normal newborns had nucleated red blood cell counts of 12 or less, while neurologically impaired newborns had an average count of 34.5. Nucleated red blood cell counts were higher when the lack of oxygen occurred earlier in the pregnancy than when the lack of oxygen was closer to birth. The rate at which nucleated red blood cells disappear after birth may indicate the type of event causing lack of oxygen.

Nucleated red blood cells: an update on the marker for fetal asphyxia
Article Abstract:
The number of red blood cells with nuclei in a brain-injured newborn's blood at birth may indicate when oxygen deprivation occurred. Researchers measured the number of nucleated red blood cells in the umbilical cord blood of 153 brain injured newborns and compared results with 83 healthy newborns. Newborns with fetal heart rate patterns indicating distress from the time of hospital admission, which suggests the problem was not labor related, averaged 49 nucleated red blood cells per 100 white blood cells versus 11 to 13 per 100 in newborns who developed distress patterns during labor and 3 in healthy newborns.
