Statement of standard

Prophylactic supplementation with vitamin K for all infants is given to prevent vitamin K deficiency bleeding (VKDB).


Rationale

Vitamin K deficiency bleeding (VKDB) in infants is prevented by vitamin K supplementation. Healthy newborn infants have low hepatic stores of vitamin K (1) and are at risk of developing serious bleeding, including intracranial hemorrhage, due to low hepatic synthesis of vitamin K–dependent clotting factors. (2,3) Preterm infants appear to be at even higher risk. (4) Vitamin K deficiency bleeding (VKDB) in infants is prevented by vitamin K supplementation. Postnatal supplementation of vitamin K can markedly reduce the incidence of VKDB, associated morbidity, including devastating brain injury, neurodevelopmental impairment and mortality. (5–7)

Healthy infants should either receive 1 mg of vitamin K intramuscular at birth, or three doses of 2 mg vitamin K orally at birth, at four to six days and at four to six weeks, respectively; or 2 mg vitamin K orally at birth followed by weekly doses of 1 mg orally for three months for breastfed infants. (3) Intramuscular application has the best preventive efficiency. (3) A prophylactic regimen for breastfed infants consisting of 1 mg vitamin K orally at birth, followed by low doses of either 25 or 150 μg daily during weeks 2 to 13, is less effective and does not adequately prevent VKDB in breastfed infants with (still undiagnosed) cholestasis. (8,9)

Intramuscular administration of 1 mg of vitamin K at birth efficiently prevents classical VKDB, but does not fully protect against late forms of VKDB. (10–14) VKDB, late form, should be considered when evaluating bleeding during the first months of life, even in infants who received vit. K prophylaxis at birth, especially in exclusively breastfed infants. (15)

The best protection is to administer newborns 1 mg of vitamin K intramuscular at birth. Vitamin K should be administered parenterally to newborn infants who are unwell, those with indications of cholestasis or impaired intestinal absorption, those who are unable to take oral vitamin K, those whose mothers have taken medications that interfere with vitamin K metabolism, and to preterm infants. (16) In preterm infants reduced doses of vitamin K prophylaxis of about 0.5 mg intramuscular for infants >1000 g or 0.2 mg intramuscular/intravenous for infants <1000 g appear to be adequate. (17) Vitamin K supplementation protocols should be developed and implemented in all obstetric and neonatal units. (3,18)

Getting started

Initial steps

For parents and family

  • Parents are verbally informed by healthcare professionals before and after birth about the importance of vitamin K supplementation and its benefits.

For healthcare professionals

  • Attend training on prevention of vitamin K deficiency bleeding (VKDB).

For neonatal unit

  • Develop a unit guideline on vitamin K supplementation in all infants.
  • Develop information material on the importance of vitamin K supplementation and its benefits for parents.

For hospital

  • Support healthcare professionals to participate in training on prevention of VKDB.
  • Provide facilities and equipment for milk expression.

For health service

  • Develop and implement a national guideline for vitamin K supplementation in all infants.
  • Raise awareness of the importance of vitamin k supplementation to effectively address common concerns and disinformation.
