Adverse neonatal outcome and veno-arterial differences in umbilical cord blood pH (ΔpH) at birth : a population-based study of 108,629 newborns
BACKGROUND: Umbilical cord blood gases are routinely used by midwives and obstetricians for quality assurance of birth management and in clinical research. They can form the basis for solving medicolegal issues in the identification of severe intrapartum hypoxia at birth. However, the scientific value of veno-arterial differences in cord blood pH, also known as ΔpH, is largely unknown. By traditio
