This is fairly common and is called polycythemia of the newborn. It is easily treated soon after birth and should have been treated then as the baby was sluggish and that is one of the main presenting symptoms. Polycythemia means an increase in the number of red blood cells in the baby's blood and is the opposite of anaemia. The baby is at risk because the increased numbers of red cells in his blood. This can interfere with the baby's circulation especially affecting organs such as the brain or kidneys. If his hemoglobin is still so high it is necessary to treat the polycythemia with a partial exchange transfusion. This treatment should be done by the baby's paediatrician.
