Umbilical Cord Blood Glucose Concentrations and Transitional Neonatal Hypoglycemia

Are umbilical cord blood glucose (UCBG) values and derived parameters associated with transitional neonatal hypoglycemia (TNH)?In this cohort study of 598 neonates, 31% developed hypoglycemia at 45 mg/dL or less and 4% at less than 30 mg/dL. Arterial and venous UCBG values, venous-arterial difference, and extraction rates were not associated with subsequent TNH.These findings suggest that UCBG parameters were not associated with subsequent TNH; however, this study provides a large, percentile-based UCBG dataset to guide future research and interpretation of neonatal glycemia.
