Meconium-stained liquor during labor is associated with raised neonatal cord blood 8-iso-prostaglandin F2-alpha concentration

Article Abstract:

The study compares the umbilical arterial 8-iso-prostaglandin F2-alpha, concentrations between pregnancies that were complicated by moderate or thick meconium stained liquor and those with clear liquor. Moderate of thick meconium-stained liquor is an independent factor for increased oxidative stress in pregnancy.
