Worldwide, vitamin K deficiency causes infant morbidity and mortality. Vitamin K deficiency causes hemorrhagic disease of the newborn, which usually occurs 1 to 7 days postpartum. In affected neonates, birth trauma can cause intracranial hemorrhage. Neonates are prone to vitamin K deficiency because of the following:
* The placenta transmits lipids and vitamin K relatively poorly.
* The neonatal liver is immature with respect to prothrombin synthesis.
* Breast milk is low in vitamin K, containing about 2.5 μg/L (cow’s milk contains 5000 μg/L).
* The neonatal gut is sterile during the first few days of life.
