In such a birth the placenta can begin to fail, causing declining delivery of oxygen and nutrients to the fetus. This can result in the death of the fetus if delivery is not induced. Postmature newborns are typically thin and underweight, with slender limbs, dry wrinkled skin and longer hair and nails.[2]
Prognosis
The first few days after delivery are the most critical, and infants living beyond that period have a high survival rate. A postmature child will have slightly less colored to gray eyes, as compared to a healthy newborn.
Eponym
It is also known as "Ballantyne-Runge syndrome".[3][4][5]
