This neonatal case presentation involves a 16 day old infant admitted to the NICU with jaundice since birth and vomiting for 1 day. Investigations revealed severe anemia, indirect hyperbilirubinemia, increased reticulocyte count, and elevated LDH. The infant received a PRBC transfusion and was discharged with improved Hb. The clinical picture is suggestive of hemolytic anemia, possibly due to fetomaternal hemorrhage given the maternal history of blood transfusions in the second trimester.

• Received PRBC transfusion 20ml/kg.
• Discharge: Hb-10.1gm%
• On follow up baby thriving well, planned for
repeat CBC at 3 months and repeat
electrophoresis at 6 months.
15. Definition:
• Defined as Hb>2 SD, below mean for postnatal
age.
• Anemia in 1st week is defined as Hb<14gm/dl.
• Any significant fall in Hb ,even if within normal
range.Eg:Birth-18.5gm% and 1st week-14gm%.
• Failure of Hb to raise during first few hours of life
–may first clue for hemolysis or hemmorage.
16. Fetal Erythropoesis:
• Erythropesis in fetus sequentially in different
sites-
-Yolk sac: maximal btw 2-10 wks
-Liver : By 6-8 wks liver is primary erytropoetic
organ
-Bone marrow:Begins at 18th week & at 30th
week is major EP organ
• Fetal EP is independent from mother.
• EPO (produced in liver)plays role in hepatic
and BM phase.
17. Fetal Erythrocyte:
• Fetal RBC-Higher O2 affinity.(no interaction 2,3 –DPG)
• Types of Hb:
- Embryonic Hb: Gower-1: ζ2 ε2
Gower-2: α2 ε2
Portland: ζ2 γ2
-Fetal Hb: Hb F: α2γ2
-Adult Hb: Hb A : α2 β2
Hb A1: α2 δ2
• Hb,HCT,and RBC count increase throuh fetal life.
• Large RBCs with increased Hb in early fetal life,size and
content decrease through gestation.
• MCV-180fl in embryo
-130fl mid gestation.
-110fl at term .
18. Neonatal Erythrocyte:
• Life span of the red blood cell (RBC) at birth is lower
than that in adult 60-70 days (preterm 35-50 days).
• Larger MCV and lower MCHC, and are more
susceptible to oxidant-induced injury mainly due to a
deficiency in phosphofructokinase activity.
• High frequency of dysmorphology of RBC in term
neonates14% are spherocytes and poikilocytes
compared to 3% in adults, more in preterm neonates.
• Rate of haemoglobin synthesis and RBC production
decreases sharply during the first few days after
delivery due to decrease in EPO in the plasma
19. Normal Values in Newborn period:
Hb and Hematocrit:
• Term infant ranges from 15.7-17.9gm/dl.
• Rises shortly(15%) after birth-absolute and
relative.
• Normal Hct:51-56% rises during few hours and
reaches original value by 1 week
20. Reticulocyte count:
Term Newborn
-At birth-3-7%
-4th day-1-3%
-7th day < 1%
• PT infants reticulocyte count is higher 6-10%
remains higher for longer period.
Nucleated RBC:
• Term infants has 0-24
NRBC/100leukocytes.(higher in PT)
• Disappear 3-4 days in Term and 7-10days in PT
21. RBC count:
4.6-5.2 million/cumm at birth,rises and returns
to normal value by 1 week
RBC indices:
MCV:105-125fl,<95fl-microcytes
MCH:35-38pg,<34pg-hypochromia
22. Etiology:
• Anemia in neonatal period is due to three
distinct causes:
1. Hemorrhage: Acute/chronic,
prenatal/postnatal
2. Hemolysis: Immune/nonimmune
3. Failure of red cell production.
23. Hemmorage:
• Prenatal Blood Loss-
-Placental –placenta previa,abruptio,vasa previa
-fetomaternal blood loss
-Retroplacental Bleed
-Twin-to-Twin Transfusion
• Postnatal Blood Loss
-skipped ligature of cord
-traumatic delivery leading to subgalel or
intrabdominal bleed.
-Iatrogenic Anemia(sampling)
24.
25. Hemolysis:
Anemia with reticulocytosis,Unconjugated
hyperbilirubinemia and hemoglobinuria without any
evidence of Hemorrhage.
1. Immune Mediated
-Rh hemolytic disease
-ABO incompatibilty.
2. Non Immune mediated
-Red cell membrane defects :Hereditary
spherocytosis, elliptocytosis,stomatocytosis
-Hemoglobinopathies:Alpha thalassemia , Gamma
thalassemia
-RBC enzyme abnormalities:G6PD deficiency , pyruvate
kinase deficiency, 5’ nucleotidase deficiency and glucose
phosphate isomerase deficiency.
-Infection:TORCH,Malaria
26. Failure of Red Cell Production
1. Congenital
-Pure red cell aplasia (Diamond-Blackfan
anemia),
-Aase syndrome and
-Fanconi’s anemia
2. Anemia of premaurity
27. Diagnostic Approach:
• History and physical examination can give a lead to the cause
of anemia in a newborn.
• Family history of anemia, cholelithiasis, unexplained jaundice
and splenomegaly - Hereditary hemolytic anemia.
• Obstetric history of difficult labor,instrumentation, bleeding or
placental abnormalities - Hemorrhagic anemia.
• The age at which anemia manifest also is of diagnostic
importance.
-Significant anemia at birth is due to blood loss or
alloimmunization.
- After 24 hours, internal hemorrhage and other causes of
hemolysis manifest.
-Anemia of prematurity, hypoplastic anemia and abnormalities
of synthesis of hemoglobin chain generally appear several
weeks after birth.
28. • Coombs test, reticulocyte count, mean
corpuscular volume, MCH and blood smear
are the key investigative tools for diagnosing
the cause of anemia in newborn.
29. Management:
Transfusion:
• Hypovolemic shock d/t acute blood loss- 10-20
ml/kg of whole blood, cross matched with
mother transfused immediately.
• Remaining situations, the decision to transfuse
takes into consideration a combination of
clinical signs and laboratory parameters.
• Transfusion products for neonatal transfusions
should be leukocyte-depleted, irradiated for
infants weighing <1200 g and from selected
donors to limit donor exposure.

Committee. Red blood cell transfusion in newborn infants. Paediatr Child
Health 2014;19:213e22.
35. Erythropoietin:
• Transitory reduction in EPO production in the first
few months after birth.
• Early administration of EPO reduces the use of RBC
transfusions, the volume transfused, number of
donor- limited clinical importance and significant
increase in ROP,reduce or increase any important
adverse outcomes including mortality,
intraventricular hemorrhage and NEC.
• Late EPO does not significantly reduce or increase
any clinically important adverse outcomes except for
a trend in increased risk for ROP

in preterm and/or low birth weight infants. Cochrane Database Syst
Rev 2014;(4):CD004868
36. Prevention:
• Delivery room practices:delayed cord clumping,milking or
striping of the umbilical cord, and drawing all NICU baseline
laboratory blood tests from fetal blood in the placenta.
• Measures to reduce blood loss: limiting phlebotomy losses for
blood testing; returning the dead space volume after sampling
an arterial catheter; microtechnique laboratory procedures;
and the development of non-invasive monitoring
• Adopting transfusion guidelines and locally adapted
transfusion criteria.
• EPO Early administration might be considered in selected
circumstances, but should not be routinely recommended.
• Iron supplementation:2010 AAP recommends iron for
breastfed term infants at 4month.
-Preterm start supplementation at 4-6wks.
• Vitamin E(5-25IU)daily upto 40 wks.
