Abstract:
Neonatal polycythaemia has multifactorial causes, and can be designated as active (increased foetal erythropoiesis) or passive (red blood cell transfusion) polycythaemia. Hematocrit estimated from capillary blood (regularly obtained through "heel sticks" in newborns) is normally the principal laboratory feature facility by which polycythaemia is recognszed. An unusually high proportion of haematocrit builds the risk of hyperviscosity, microcirculatory hypoperfusion, and in the long run multisystem organ dysfunction. A report enclosed in this short communication gives a brief review of neonatal polycythaemia, its causes, management and complications.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Erythropoiesis
Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
