A study reports the results of serial measurements of serum vitamin K levels in newborn low birthweight infants following an oral dose of 2.0 mg vitamin K. Peak serum levels resulted 6-12 hours after dosing with a 20-fold increase in the median level. The results indicate that normal or a high serum vitamin K can be achieved by the end of the first week in life, but it is notknown whether this dosage is sufficient to maintain normal serun vitamin K levels and normal coagulant activities later on. Prolonged blood clotting, especially in breast-fed infants, is due to vitamin K deficiency and supplementation in newborn infants must be recommended. (wz)
