Vitamin K
Özet
Bu bölüm, K vitamininin pediatrik sağlık üzerindeki kritik rolünü detaylandırmaktadır. K vitamini, kanın pıhtılaşmasını sağlayan faktörlerin aktivasyonunda görev alarak bebeklerde ve çocuklarda kanama riskini azaltır. Yenidoğanlarda K vitamini eksikliği, potansiyel olarak hayatı tehdit edebilen kanama bozukluklarına yol açabilir ve bu nedenle doğum sonrası K vitamini takviyesi önerilmektedir. Ayrıca, K vitamini kemik gelişimini destekler ve kardiyovasküler sağlığı koruyarak damar sertliğini önleyebilir. Bölümde K1 (filokinon) ve K2 (menakinon) formlarının biyolojik işlevleri, diyet kaynakları ve metabolizması ele alınmaktadır. Aynı zamanda, K vitamini eksikliğinin klinik bulguları, eksikliğe neden olan faktörler ve farmakolojik tedavi yöntemleri incelenmektedir. Bu kapsamda, çocukluk ve ergenlik döneminde K vitamini ihtiyacının nasıl karşılanması gerektiği ve profilaktik önlemler de tartışılmaktadır.
