Management of Thrombocytosis and Epigastric Pain in Sickle Cell Disease

Immediate Assessment and Supportive Care

  • The American College of Physicians recommends aggressive intravenous hydration to prevent dehydration in sickle cell patients, as they have impaired urinary concentrating ability and become dehydrated easily 1, 2, 3
  • Maintaining adequate fluid balance with close monitoring is crucial to prevent progression to life-threatening complications 1, 2, 3
  • The American Thoracic Society recommends maintaining SpO2 above baseline or 96% with continuous monitoring to provide early warning of acute chest syndrome 2, 4
  • The American Pain Society recommends using patient-controlled analgesia (PCA) as the preferred method for severe pain requiring parenteral opioids, with hydromorphone being an appropriate choice 4, 5
  • The American Society of Anesthesiologists recommends maintaining normothermia actively, as hypothermia leads to shivering, peripheral stasis, hypoxia, and increased sickling 2, 6

Thrombocytosis Management

  • The American Society of Hematology recommends treating extreme thrombocytosis in sickle cell disease with hydroxyurea 1, 2, 3
  • The American College of Chest Physicians recommends routine thromboprophylaxis for all peri- and post-pubertal patients due to increased deep vein thrombosis risk 2, 3

Multidisciplinary Approach

  • The American Society of Hematology recommends daily assessment by a hematologist for patients with acute complications 2, 6
  • The Infectious Diseases Society of America recommends obtaining blood cultures if the patient becomes pyrexial, and starting antibiotics if temperature is ≥38.0°C or if signs of sepsis develop 2, 6

Nutritional Management During Crisis

  • The American Society for Nutrition recommends encouraging patients to maintain adequate oral fluid and nutritional intake as tolerated 1
  • The American Gastroenterological Association recommends maintaining oral intake to support hydration status, which is critical given impaired urinary concentrating ability 1
  • The American Society for Parenteral and Enteral Nutrition recommends adequate fiber intake and hydration to prevent constipation in patients receiving opioid analgesics 1

Critical Pitfalls to Avoid

  • The American College of Physicians recommends not giving iron supplementation unless iron deficiency is biochemically proven, due to risk of iron overload from repeated transfusions 7
  • The American Society of Anesthesiologists recommends not assuming patients should be NPO during pain crises without specific clinical indications 1
