Article Abstract:
Multiple studies have reported an association between elevated umbilical cord nucleated red blood cell (NRBC) counts and adverse perinatal outcomes such as abnormal fetal heart rate (FHR) patterns, intrauterine academia, and neurologic impairment. The fact that NRBC counts were elevated in fetuses who were delivered for nonreassuring fetal status with erythropoietin being normal and interleukin-6(IL-6) being elevated implies that IL-6 may have a unique, short-term role in elevating fetal NRBC counts.

Article Abstract:
Fetal pulse oximetry is used to quantify the impact of maternal oxygen administration in the management of nonreassuring fetal heart rate patterns. The results have shown that the administration of supplemental oxygen to laboring patients with nonreassuring fetal heart rate patterns have increased the fetal oxygen saturation substantially, where the fetuses with the lowest initial oxygen saturations appear to increase the most.

Article Abstract:
Unborn babies with an abnormal fetal heart rate pattern are also likely to have nucleated red blood cells after birth, according to a study of 279 pregnancies. Nucleated red blood cells are immature blood cells that normally disappear at birth. If they persist after birth, that is a sign that the baby did not get enough oxygen before birth. An abnormal fetal heart rate is also a sign of low oxygen levels.
