Assessment and Management of Patients With Hematologic Disorders – Part 2 :Assessment and Management of Patients With Hematologic Disorders – Part 2 Loretta Elder RN MSN CAPA
Anemia :Anemia A condition of a lower than normal level of Hgb, which reflects fewer than normal RBC in circulation. As a result, the amount of oxygen delivered to tissues is decreased.
Can result from dietary problems, genetic disorders, bone marrow disease or excessive bleeding (i.e. GI Bleed)
See Table 33-2 1045 for Classifications of Anemia
Anemias: :Anemias: Hemolytic(result from increased destruction RBC
Sickle Cell
G6PD deficiency
Immunohemolytic
Thalessemia Anemia that result from deficiency of RBC
Iron Deficiency
Vitamin B12 Deficiency
Folic Acid Deficiency
Aplastic
Polycythemia
Myelodysplastic Syndrome
Sickle Cell Disease-1055 :Sickle Cell Disease-1055 Main problem in this disorder is the formation of abnormal hemoglobin chains
The normal adult hemoglobin is called HemoglobinA(HbA)
In sickle cell disease, there is an abnormality in the beta chains known as HemoglobinS(HbS)
HbS is very sensitive to oxygen levels of the RBC
SICKLE CELL CRISIS
Sickle Cell Disease :Sickle Cell Disease A pair of genes, one from each parent, is needed for the abnormal beta chains to form
When the individual inherits one gene from a parent, that individual has Sickle Cell Trait
Genetic counseling is needed because this individual can pass on the trait and if the genetic material is combined with another individual who also has the trait the likelihood of Sickle Cell Disease increases
Sickle Cell Disease occurs when the individual receives two abnormal genes, one from each parent
Abnormal hemoglobin is called Hemoglobin S (HgS)
Sickle Cell Disease :Sickle Cell Disease A genetic disorder
Most common in African Americans (some Mediterranean, Caribbean, Middle Eastern, & Central American groups)
Assessment: :Assessment: Adult usually has long standing diagnosis of the disorder
Adult with sickle cell trait may be unaware of a problem until there is an acute illness or anesthesia is administered
History:
Sickle Cell Disease :Sickle Cell Disease Clinical Manifestations
1056
Diagnostics:
Xray may show skull “crew cut” from bone cell surface destruction and regrowth.
Joint xrays may show necrosis
EKG, CT MRI – show organ and soft tissue damage from tissue hypoxia Diagnosis-based on percentage of Hbs
Electrophoresis
Sickle Cell Trait have less than 40%HbS
Sickle Cell Disease have 80-100%
Does not change during crisis
Hematocrit (Hct)
Sickle Cell Disease is low-Decreases more during crisis
Bilirubin and WBC usually higher

Sickle Cell Disease in Child :Sickle Cell Disease in Child Symptoms of disease not usually present until after 4-6 months due to large amounts of HbF present in the first few months of life.
Delayed growth and puberty usually present.
Child usually has small stature until age 20.
Glucose-6-Phosphate Dehydrogenase Deficiency Anemia-1061 :Glucose-6-Phosphate Dehydrogenase Deficiency Anemia-1061 A hemolytic anemia that develops when there is a deficiency of the enzyme G6PD
Enzyme is responsible for energy production that helps maintain the structure of the cell membrane
Cells with inadequate G6PD are more likely to lyse as the cells age
These RBCs are also more likely to lyse with certain drugs
sulfonamides, aspirin, quinine derivatives, thiazide diuretics, and vitamin K derivatives.
Toxins also cause
Stressors also trigger this anemia
MUST REMOVE SOURCE
Glucose-6-Phosphate Dehydrogenase Deficiency Anemia :Glucose-6-Phosphate Dehydrogenase Deficiency Anemia Symptoms usually take several days to develop
Usually asymptomatic until exposed
Usually see anemia and jaundice
Acute tubular necrosis (due to waste & Hgb in Kidney)
Treatment

Avoid Exacerbating Drugs
Avoid Stressors
Hydration

Possible Transfusion
Immunohemolytic Anemia-1062RBC’s are viewed as non-self by the immune system and are destroyed :Immunohemolytic Anemia-1062RBC’s are viewed as non-self by the immune system and are destroyed Results from trauma to RBCs
Caused by hemodialysis machines, cardiopulmonary bypass machines, prosthetic heart valves, burns, radiation, antibody reactions, drugs, toxins, and chemical agents. Clinical Manifestations

Treatment
Immunosuppressive Therapy, Blood Transfusions, Fluid and Electrolyte Replacement, Splenectomy, Folate, and Steroid Therapy
Thalassemia – Cooley’s Anemia-1061 :Thalassemia – Cooley’s Anemia-1061 Inherited disorder, similar to Sickle Cell
When the disorder is mild, the person may have normal hemoglobin and few signs and symptoms
When severe, the person may need transfusion to sustain life
Incidence highest in individuals of Mediterranean descent
Clinical Manifestations
Small Stature (bone pain), Fractures (of long bones, ribs, and vertebrae), Hepatomegaly, Hemolysis, Severe Anemia and Hypoxia, Febrile, Pallor & Jaundice
Iron overload can also occur from the repeated transfusions
Diagnosis
Hgb ↓
RBCs are Microcytic, Hypochromic
Fragile RBCs, Bull’s eye appearance (target cells)
Most often diagnosed during infancy due to low Hgb levels
Prognosis
Adult usually has milder form
Persons with severe thalassemia may live into their 20’s
Thalassemia in the Child :Thalassemia in the Child See: Protruding forehead, maxillary prominence, wide set eyes with a flat nose, greenish yellow skin tone.

Increase Dietary Iron
Oral Supplements (Ferrous Sulfate)
Parenteral Iron Sources
Iron Deficiency AnemiaIn Children :Iron Deficiency AnemiaIn Children Most common cause of anemia in infancy, childhood and adolescence
Rare before 4-6 months due to presence of maternal iron stores
Decreased iron intake is often related to the intake of large amounts of cow’s milk instead of breast milk/iron fortified formula.
Adolescents are at risk due to increased growth rate and poor eating habits.
Usually treated with oral iron preparation as increased diet in iron is usually not enough.
Vitamin B12 Deficiency Anemia-1052 :Vitamin B12 Deficiency Anemia-1052 Megaloblastic Anemia
Due to improper DNA synthesis and increased size of cells
Pernicious Anemia
Due to a deficiency of adequate intrinsic factor (IF)
Essential for intestinal absorption of B12
Often the result of chronic gastritis or gastrectomy
Other causes are loss of pancreas, loss of ileum, & strict vegetarians (rare)
