Sickle Cell Disease (SCD) is a genetic disorder characterized by the abnormal shape of red blood cells due to a mutation in the hemoglobin gene. This condition is inherited when both parents pass on the gene responsible for producing hemoglobin S. Unlike normal hemoglobin, which consists of four peptide chains, SCD results from a mutation in the HBB gene, producing abnormal hemoglobin S (HBS). This genetic mishap causes the normally round and flexible red blood cells to become sickle or crescent-shaped, impairing their ability to transport oxygen effectively.

Understanding SCD is crucial, particularly in regions where it is prevalent, as it affects individuals of African-American descent and those with a family history of the disease. Diagnosis involves a thorough medical history, physical examination, and blood tests, often initiated through newborn screening and confirmed with hemoglobin electrophoresis.

The clinical manifestations of SCD can vary, with early signs including jaundice, fatigue, and dactylitis, while later symptoms encompass anemia, sickle cell crises, acute chest syndrome, splenic sequestration, and priapism. Therapeutic management includes Voxelotor, pain relievers, hydroxyurea, and folic acid. Blood and bone marrow transplants and potential genetic therapies are also considered. Nursing care for SCD patients involves supportive measures such as hydration, vaccination education, eye exams, and monitoring of pulmonary function. Pain management and addressing complications like stroke, pulmonary hypertension, organ damage, blindness, gallstones, and leg ulcers are critical aspects of care.

In explaining SCD to a child, it’s essential to use age-appropriate language and analogies. One might describe how red blood cells are normally round like doughnuts, but in SCD, they can become shaped like bananas, making it hard for them to carry oxygen.
