Polycythemia in newborns is defined as hematocrit > 65%. Significant polycythemia can be associated with blood hyperviscosity, or thickening of the blood. Causes of neonatal polycythemia include: Hypoxia: Poor oxygen delivery (hypoxia) in utero resulting in compensatory increased production of red blood cells (erythropoeisis). Hypoxia can be ...
