Sickle cell disease is characterized by recurrent episodes of acute pain. Some patients also suffer from chronic pain syndromes including avascular necrosis, leg ulcers, and intractable pain. Approaches to rational therapy of sickle pain include pharmacologic, nonpharmacologic, and preventive therapeutic interventions. ⋯ Administration of opioids on a fixed schedule or by patient-controlled analgesia is ideal for effective therapy. Nonpharmacologic approaches to manage sickle pain are underutilized and more studies are needed to determine their role in sickle pain. Preventive therapy of sickle pain is best achieved with hydroxyurea, which was found to decrease the frequency of crises significantly, decrease the incidence of acute chest syndrome, and decrease the need for blood transfusion.
