Vitamine K orale chez les bébés allaités exclusivement : quelle dose, combien de temps ?

Abstract

There are various ways to prevent late vitamin K deficiency bleeding in exclusively breast-fed infants. The French paediatric society recommends weekly doses of 2 mg of mixed micellar preparation of vitamin K during the entire period of exclusive breastfeeding, i.e. 24 doses for a period of six months, which matches recommendations for optimal duration of exclusive breastfeeding by the French paediatric society, WHO and AAP. This significantly exceeds recommendations in other European countries. We describe the risks of vitamin K deficiency; we provide a review of recent literature about administrating vitamin K in other countries, and give a recommendation for daily practice that seems to be acceptable. Nevertheless, a comprehensive randomised prospective study is needed in France to answer the question of the best ways of preventing vitamin K deficiency bleeding.
