When is the administration of vitamin K recommended for newborns?

The administration of vitamin K is recommended for newborns within the first hour after birth to help prevent vitamin K deficiency bleeding (VKDB), a serious condition that can lead to bleeding in the brain and other organs. Newborns naturally have low levels of vitamin K, which is essential for blood coagulation, due to limited transfer from the placenta and low vitamin K content in breast milk.

Giving vitamin K shortly after birth helps ensure that the infant has adequate levels of this vital vitamin to promote proper blood clotting. The timing is crucial as newborns are at a greater risk of bleeding during the first few days and weeks of life. By administering vitamin K within the first hour, healthcare providers can significantly reduce the risk of this potentially life-threatening condition.

The other timing options and conditions for vitamin K administration do not align with standard medical guidelines. Delaying vitamin K administration beyond the first hour or administering it only under specific conditions, like the presence of bleeding, diminishes the preventive benefits for all infants, regardless of their bleeding status.
