L10: Bleeding Disorders in Newborn Flashcards
Causes of Bleeding in Newborn
Incidence of Hemorrhagic Disease of the Newborn
- 1/200 - 400 babies not given vitamin K prophylaxis.
- The most common cause of bleeding in newborns.
Etiology of Hemorrhagic Disease of the Newborn
Deficiency of vitamin K dependent coagulation factors II, VII, IX, and X.

INVx for Hemorrhagic Disease of the Newborn
Management of Hemorrhagic Disease of the Newborn
Management of Hemorrhagic Disease of the Newborn
- Prophylactic
- Early feeding
- Vitamin K (1 mg) at the time of delivery
Management of Hemorrhagic Disease of the Newborn
- Therapeutic
- Vitamin K (5 mg IV or IM).
- Fresh frozen Plasma or fresh blood transfusion especially in severe hemorrhageโ
Etiology of DIC in Newborn
Pathogenesis of DIC in Newborn
CP of DIC in Newborn
The baby is usually in bad general health (i.e., not active).
INVx for DIC in Newborn
TTT of DIC in Newborn
- TTT of the cause
- Supportive care: platelet transfusions, FFP & Cryoprecipitate โto control bleedingโ.
Prognosis of DIC in Newborn
Poor
Def of Thrombocytopenia in Newborn
PLT count < 150.000/mm3
Etiology of Thrombocytopenia in Newborn
Etiology of Thromboasthenia in Newborn
- Inherited (e.g., Glanzman disease).
- Platelet dysfunction (due to maternal drugs e.g., aspirin)
Etiology of IFD in Newborn
- Congenital afibrinogenemia. (Factor 1)
- Factor VIII deficiency.
Causes of Traumatic Bleeding in Newborn
Birth injuries lead to:
- Rupture of liver & spleen in breech delivery
- Subdural hematoma
- Cephalhematoma
- Subgaleal hemorrhage

TTT of Neonatal Bleeding
- Vit K
5mg
TTT of Neonatal Bleeding
- FFP
10 ml/kg for active bleeding to replace the clotting factors
TTT of Neonatal Bleeding
- Platelet Transfusion
5-10ml/kg could raise platelet count by 10.000 PL./mm3
TTT of Neonatal Bleeding
- Fresh Whole Blood
10-20 ml/kg if there is severe anemia or severe Hge
