In a sickle cell crisis, which intervention is considered the initial management priority?

Hydration is the initial management priority because dehydration promotes HbS polymerization and vaso-occlusion. Aggressive IV fluids dilute the sickled cells, reduce blood viscosity, and improve microvascular flow, helping to reverse or lessen the crisis. Pain control should be started promptly as well, but fluids address the underlying driver of the crisis. Oxygen therapy is reserved for documented hypoxemia, since giving oxygen to someone who isn’t hypoxic doesn’t prevent sickling. Exchange transfusion is reserved for severe complications or refractory cases (like acute chest syndrome or stroke) and isn’t the first step.
