Low Apgar score has been universally associated with MAS [1, 3, 6, 9, 11–16, 28, 32, 39, 40], and the role of fetal hypoxia has also been ascertained by elevated cord blood concentrations of erythropoietin in both MSAF [41] and MAS [32, 42]. This evidence concerns the gene EPO and meconium aspiration syndrome.
