[Clinical features of severe meconium aspiration syndrome (MAS) and early predicting factors for severe MAS in neonates with meconium-stained amniotic fluid].

Meconium suctioning cannot completely prevent the onset of severe MAS in neonates with MSAF. The neonates with severe MAS may develop severe respiratory distress and require mechanical ventilation early after birth. Close monitoring of blood lactate in the umbilical artery and peripheral blood IL-6 and WBC at 1 hour after birth may help with early prediction of the development and severity of MAS.
