Introduction: Increased numbers of nucleated red blood cells (NRBC) circulating in the blood of neonates can be associated with relative hypoxia and adverse outcomes. Thus, the aim of this study was to assess the NRBC count during the first week of life in neonates diagnosed with asphyxia as compared to healthy neonates and to determine the short-term morbidity and mortality for the affected babies. Methods: The cross-sectional study compared 15 healthy neonates with 15 neonates diagnosed with asphyxia confirmed by pH of cord blood or Apgar scores. The nucleated red blood cell (NRBC) counts were calculated right after birth, and on days 3 and 7, and the hematological parameters of umbilical cord blood were also evaluated. The infants were followed for mortality and associated morbidity. Statistical analysis was conducted using the Mann-Whitney U test, analysis of variance, chi-square tests, and Pearson’s correlation coefficient. A p-value < 0.05 was considered as statistically significant. Results: The initial NRBC counts were significantly higher in the asphyxiated group than in the control group and the difference remained significant through the end of first week. All of the umbilical cord blood parameters were significantly lower in the study group and were negatively correlated with the NRBC count. At birth, higher NRBC count correlated with higher mortality. conclution: Results show that NRBC count is a useful predictive factor for neonatal asphyxia through the end of the first week of life, although a larger study population and a longer follow up period seems to be necessary.
