Anemia Flashcards
Microcytic
MCV < 80
Normocytic
MCV 80-96
Macrocytic
MCV > 96
Hypochromic
MCH Low
Normochromic
MCH Normal (27-33)
Macrochromic
MCH High
Macrocytic Anemia causes
Vit B12 Deficiency
Alcoholism
Liver disease
DNA replication inhibitors (Methotrexate)
Normocytic Anemia
Acute blood loss
Chronic bone disease
Bone marrow failure
Hemolysis
Microcytic Anemia
Hem synthesis defect – iron deficiency, chronic disease
Globin synthesis – thalassemia, sideroblastic defect
Sickle Cell (inherited)
- Pain is cardinal subjective symptom of sickle cell crisis, nausea, anorexia, lightheaded anxiety, SOB, palpitations.
- Patients should be instructed to avoid triggers (cold, heat, dehydration), maintain adequate hydration, correct hypoxia if needed.
- Acute treatment – aggressive IV or oral hydration, pain relief, PO Benadryl to control pruritis from opiate analgesics, Hydroxyurea, transfusions
Normocytic, Normochromic
Thalassemia
Microcytic, hypochromic,
RDW normal
* Minor = no treatment, avoid iron for incorrect dx.
* Major = Transfusion
IDA (MOST COMMON)IDA (MOST COMMON)
Microcytic, hypochromic,
RDW high (longstanding will be normal)
* Signs - stomatitis, glossitis (burning tongue), brittle fingernails, platonychia, koilonychia, PICA.
* Instruct on diet rich in foods containing iron such as organ meats, red meat, dried peas and beans, dark veggies, whole grains.
* 150-200 mg/d elemental iron when deficient for 4-6 months.
* Serum ferritin – if you see changes in MCV, MCH, add it on to labs – single most powerful test for IDA
