During a sickle cell crisis, which intervention is commonly used?

• A. Intravenous Hydration
• B. Oxygen Therapy
• C. Spleenectomy
• D. Antibiotics

Answer: (A)

Hydration to reduce sickling is a central part of managing a vaso-occlusive crisis. Dehydration raises the concentration of HbS in the blood, promoting polymerization and further sickling of red cells. Providing intravenous fluids helps dilute HbS, lowers blood viscosity, and improves microvascular flow, which eases pain and tissue perfusion during the crisis.

Oxygen therapy is used if the patient is actually hypoxic or in respiratory distress; giving oxygen to someone who isn’t hypoxic doesn’t reliably improve crisis outcomes, so it isn’t routinely used for all patients.

Splenectomy isn’t an acute treatment for a vaso-occlusive crisis; it’s reserved for other splenic problems like sequestration or chronic issues, not for immediate crisis management.

Antibiotics are important when there is suspected infection, especially in patients with functional asplenia, but they’re not the standard intervention for a sickle cell crisis itself unless there’s evidence of infection.
