Study Notes
Mechanisms of Anemia
- Increased RBC Loss: This can occur due to bleeding, menstruation, or other causes of blood loss.
- Increased Destruction: This can happen due to conditions like sickle cell anemia or autoimmune disorders.
- Deficient Production: This can be caused by deficiencies in essential nutrients like iron, vitamin B12, or folic acid.
Morphology of Anemia
- Normocytic: Red blood cells are normal in size.
- Microcytic: Red blood cells are smaller than normal.
- Macrocytic: Red blood cells are larger than normal.
- Normochromic: Red blood cells have a normal amount of hemoglobin.
- Hypochromic: Red blood cells are paler than normal (due to low hemoglobin).
- Megaloblastic: Large red blood cells with abnormal DNA synthesis, often seen in Vitamin B12 or folic acid deficiency.
Etiology of Anemia
-
Hypoproliferative Anemia: Decreased production of red blood cells.
- Iron Deficiency Anemia: Insufficient iron for hemoglobin production.
- Megaloblastic Anemia: Defective red blood cell production due to vitamin B12 or folate deficiency.
- Aplastic Anemia: The bone marrow fails to produce enough red blood cells. This is a serious condition that can affect all blood cell types (pancytopenia)
-
Hemolytic Anemia: Increased breakdown of red blood cells.
- Sickle Cell Anemia: A genetic disorder characterized by abnormally shaped red blood cells, often causing blood clots and pain.
Management of Anemia
- Laboratory Investigations: Blood tests (CBC, blood smear, etc.) to diagnose the cause of anemia.
- Treat the Underlying Cause: Address the source of the anemia, whether it’s iron deficiency, vitamin deficiency, or another medical condition.
- Blood Transfusions: In severe cases, blood transfusions can be used to replace the lost red blood cells.
- Nutritional Supplements: Iron, vitamin B12, or folic acid supplements may be needed depending on the cause of anemia.
Nursing Diagnoses & Management
Hypoproliferative Anemia
-
Activity Intolerance:
- Promote optimal activity and protect from injury, encourage patient participation in self-care.
- Provide adequate rest periods, re-plan activities that cause fatigue.
- Avoid sudden movements.
-
Decreased Cardiac Output:
- Monitor vital signs, signs of heart failure (edema, neck vein distention, decreased urine output, palpitations).
Iron Deficiency Anemia
-
Activity Intolerance:
- Manage fatigue and prevent complications:
- Encourage rest, promote quiet activities.
- Provide oxygen supplementation as needed.
- Position patient in Fowler’s position.
- Manage fatigue and prevent complications:
-
Support RBC Production:
- Improve diet:
- Encourage a nutritious diet.
- Provide iron and vitamin supplements.
- Encourage small, frequent meals.
- Improve diet:
Folic Acid Deficiency
-
Common Causes:
- Poor intake: Low socioeconomic status, inadequate dietary intake.
- Absorption Problems: Pregnancy, lactation, rapid growth, infants.
Blood Loss Anemia
-
Acute Blood Loss:
- Symptoms occur rapidly, leading to hypovolemia and circulatory collapse.
- Can be managed by replacing lost blood through transfusions.
-
Chronic Blood Loss:
- Occurs over a longer period, leading to iron deficiency and low hemoglobin.
- Requires addressing the underlying cause of chronic blood loss.
Iron Deficiency Anemia
-
Causes:
- Low Iron: Inadequate iron intake, malabsorption, blood loss, increased iron demand (pregnancy).
- Blood Loss: Menstruation, bleeding from the gastrointestinal or genitourinary systems, surgery.
-
Characteristics:
- Decreased number of red blood cells.
- RBC indices: Microcytic, hypochromic (smaller, paler red blood cells).
-
Diagnostics:
- CBC: Complete blood count to assess red blood cell count and hemoglobin levels.
- Peripheral blood smear: To examine the size and shape of red blood cells.
-
Management:
- Remove the causative agent: Address the cause of iron deficiency, such as heavy menstrual bleeding or gastrointestinal bleeding.
- Iron supplements: Oral or intravenous iron supplementation.
- Diet: Increase dietary intake of iron-rich foods, such as red meat, leafy green vegetables, beans.
- Bone marrow transplant (BMT) or peripheral blood stem cell transplant (PBSCT): For severe, refractory iron deficiency anemia.
Other Important Considerations
-
Vitamin B12 Deficiency (Pernicious Anemia):
- Causes: Autoimmune disorders, malabsorption, surgery.
- Management: Vitamin B12 injections for life.
-
Aplastic Anemia:
- Causes: Autoimmune disease, radiation, toxins.
- Management: Immunosuppressive therapy, bone marrow transplant.
