Hypoxic ischemic encephalopathy
HIE can occur prenatally during various stages of fetal development due to preeclampsia, maternal diabetes with vascular disease, congenital fetal infections, maternal drug / alcohol abuse, severe fetal anemia, cardiac disease, lung malformations, or problems with placental blood flow. HIE may also occur during labor and delivery due to umbilical cord occlusion, torsion, or prolapse, rupture of the placenta or uterus, excessive placental bleeding from the placenta, or abnormal fetal position.
