At birth, hemoglobin F accounts for 50-95% of the infant's hemoglobin and at around 6 months after birth, hemoglobin A becomes the predominant type. By the time the baby is one year old, the proportions of different types of hemoglobin are expected to approximate the adult levels, with hemoglobin F reduced to very low levels. [4]
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.
The pink hemoglobin-containing supernatant is then mixed with 1 mL of 1% NaOH for each 5 mL of supernatant. The color of the fluid is assessed after 2 minutes. Fetal hemoglobin will stay pink and adult hemoglobin will turn yellow-brown since adult hemoglobin is less stable and will convert to hematin which has a hydroxide ligand. [5]
Neonatal jaundice is a yellowish discoloration of the white part of the eyes and skin in a newborn baby due to high bilirubin levels. [1] Other symptoms may include excess sleepiness or poor feeding. [1] Complications may include seizures, cerebral palsy, or kernicterus. [1] In most of cases there is no specific underlying physiologic disorder. [2]
[24] [25] Because anemia during pregnancy can result in poorer outcomes for the mother and her baby, the complete blood count is a routine part of prenatal care; [26] and in newborn babies, a CBC may be needed to investigate jaundice or to count the number of immature cells in the white blood cell differential, which can be an indicator of sepsis.
The below tests are often useful in cases of hemolytic disease of the newborn but are not required for treatment of all newborns. Hgb — the infant's hemoglobin should be tested from cord blood. [6] Reticulocyte count — Reticulocytes are elevated when the infant is producing more red blood cells in response to anemia. [6]
A large volume transfusion is the estimated entire blood volume of the baby (80 ml/kg) and is usually given during cardiac surgery. [1] 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 ...
