Existem 3 formas de sangramento por deficiência de vitamina K (SDVK) do recém-nascido. SDVK inicial (doença hemorrágica do recém-nascido) que ocorre entre 1 e 14 dias de idade. Os locais mais comuns de sangramento são o trato gastrointestinal, o tecido mucoso e cutâneo, o coto umbilical e o local pós-circuncisão. O SDVK tardio ocorre mais comumente entre 2 e 12 semanas de idade, embora os casos possam ocorrer até 6 meses. O local mais comum de sangramento é intracraniano, embora sangramento cutâneo e gastrointestinal possam ser manifestações iniciais. A terceira forma de SDVK ocorre no nascimento ou logo depois. É secundária à ingestão materna de medicamentos (warfarina, fenobarbital, fenitoína) que atravessam a placenta. | |||
