1. Causes of anemia
The most common causes, including:
Obstetric causes: such as placental abruption, placenta previa, trauma to the placenta or umbilical cord at birth, abnormal blood vessel rupture of the placenta, ruptured umbilical cord. Fetal-maternal blood transfusion: 8% of normal pregnant mothers have maternal blood transfusion. Fetal blood transfusion – placenta. Twin blood transfusion. Blood loss due to bleeding such as intracranial bleeding, subdural bleeding, subcutaneous hematoma. Blood loss due to treatment, such as excessive blood collection, is most common in premature infants. Increased destruction of red blood cells
In red blood cells: G6PD deficiency, sickle cell disease, α- thalassemia. In addition to red blood cells: Immune hemolysis (such as incompatibility of the ABO, Rh, and subgroups...), hemangioma (Kasabach Merritt syndrome), acquired hemolysis (due to infection, drug use) ...) Decreased red blood cell production
Anemia in premature infants due to transient erythropoietin deficiency; Anemia due to hypoplasia or marrow aplasia; Bone marrow suppression (Rubella or Parvovirus 19 infection); Nutritional anemia (iron deficiency) is common after infancy.
