This combination can lead to vitamin K deficiency and later onset bleeding. Vitamin K deficiency leads to the risk of blood coagulation problems due to impaired production of clotting factors II, VII, IX, X, protein C and protein S by the liver. More rarely VKDB can be caused by maternal medicines causing vitamin K deficiency in the newborn. [2]
Therefore, the Committee on Nutrition of the American Academy of Pediatrics recommends that 0.5 to 1.0 mg Vitamin K 1 be administered to all newborns shortly after birth. [4] Postmenopausal and elderly women in Thailand have a high risk of Vitamin K 2 deficiency, compared with the normal value of young, reproductive females. [5]
Some parents may refuse the vitamin K shot given at birth to help reduce risk of HDN, and in these cases oral vitamin K can be administered. This alternative is evaluated on a case-by-case basis as there are no guidelines for oral vitamin K for infants in the U.S. [ 22 ] Vitamin K supplementation via the oral route of administration may require ...
Phytomenadione, also known as vitamin K 1 or phylloquinone, is a vitamin found in food and used as a dietary supplement. [6] [7] It is on the World Health Organization's List of Essential Medicines. [8] It is used to treat certain bleeding disorders, [7] including warfarin overdose, vitamin K deficiency, and obstructive jaundice. [7]
Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues. [2]
Newborn infants are a special case. Plasma vitamin K is low at birth, even if the mother is supplemented during pregnancy, because the vitamin is not transported across the placenta. Vitamin K deficiency bleeding (VKDB) due to physiologically low vitamin K plasma concentrations is a serious risk for premature and term newborn and young infants.
