Hyperhemolysis syndrome (HHS) is a catastrophic unpredictable consequence of blood transfusion in sickle cell disease. It leads to further drop in hemoglobin via immune mechanisms complicating a hospital course and prolonging length of stay. Although sickle cell patients receive multiple transfusions throughout their disease course, this condition remains underreported by health care professionals or misinterpreted for other sickle cell crises. We present a similar case highlighting the importance of early recognition of HHS and judicious blood transfusion in sickle cell disease patients to avoid such a complication.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

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.
