Abstract

Aim: To investigate the vitamin K status of preterm infants who have a prolonged prothrombin time (PT) in the first month of life. Methods: Measures of vitamin K status were assessed in 21 preterm infants who were found to have an abnormal PT, despite 0.2-0.5 mg vitamin K1 prophylaxis at birth. Results: All infants had normal or supraphysiological vitamin K1 concentrations and undetectable or, in one infant, insignificant PIVKA-II, indicating adequate vitamin K status. Conclusion: In preterm infants born at < 32 wk gestation who received ≥ 0.2 mg vitamin K1 after delivery, a prolonged PT in the first month of life is unlikely to be due to vitamin K deficiency.
