If the anemia is severe, it can be treated with a blood transfusion, however this is rarely needed. On the other hand, neonates have underdeveloped livers that are unable to process large amounts of bilirubin and a poorly developed blood–brain barrier that is unable to block bilirubin from entering the brain.
Anemia of prematurity (AOP) refers to a form of anemia affecting preterm infants [1] with decreased hematocrit. [2] AOP is a normochromic, normocytic hypoproliferative anemia. The primary mechanism of AOP is a decrease in erythropoietin (EPO), a red blood cell growth factor.
A red cell exchange transfusion is usually given to treat severe hyperbilirubinemia or anemia in babies with hemolytic disease of the newborn. It removes neonatal red cells coated with maternal antibody and reduces the level of bilirubin. A ‘double volume exchange’ (160–200 ml/kg) removes around 90% of neonatal red cells and 50% of ...
Hemolytic disease of the newborn, also known as hemolytic disease of the fetus and newborn, HDN, HDFN, or erythroblastosis fetalis, [1] [2] is an alloimmune condition that develops in a fetus at or around birth, when the IgG molecules (one of the five main types of antibodies) produced by the mother pass through the placenta.
Hemolytic disease of the fetus and newborn (HDN) is a condition where the passage of maternal antibodies results in the hemolysis of fetal/neonatal red cells. The antibodies can be naturally occurring such as anti-A, and anti-B, or immune antibodies developed following a sensitizing event. [ 11 ]
In diseases such as sickle cell anemia, blood is removed and replaced with donor blood. [ 5 ] In conditions such as neonatal polycythemia, a specific amount of the child’s blood is removed and replaced with normal saline, plasma (the clear liquid portion of blood), or an albumin solution.

It is a potential cause of neonatal hemolytic anemia. Infantile pyknocytosis typically presents with neonatal jaundice and severe anemia, often requiring blood transfusions. The associated hemolytic anemia is often transient with peak incidence at 3–4 weeks, with spontaneous and complete resolution by four to six months of life. [2]
