Pain exacerbates hypoxemia and metabolic demand, while hypoxia directly triggers hemoglobin S polymerization.
Assess pain using a developmentally appropriate scale and administer opioid analgesics promptly, often via IV for rapid onset. Avoid cold compresses as they cause vasoconstriction and can worsen sickling; apply warm compresses to painful areas instead.
Do not delay analgesia for a patient with severe pain. Encourage incentive spirometry to prevent acute chest syndrome, and initiate IV fluid resuscitation rather than oral intake if nausea is present.
