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 Monitor for S/S anemia, fever, kidney malfunction Avoid Exacerbating Drugs Avoid Stressors Hydration Osmotic Diuretics – Mannitol (Osmitrol) 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 Hepatosplenomegaly, Jaundice, Pathologic Fractures, and S/S Similar to Other Anemias 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.

Iron Deficiency Anemia-1049 Clinical Manifestations Similar to Anemia RBCs are microcytic Laboratory Values Serum Iron Concentration ↓ Total Iron-Binding Capacity ↑ Serum Ferritin Levels ↓ Inadequate supply of Iron causes a decrease in Hgb Common in elderly, women and people with poor diets.

Iron Deficiency Anemia : 

Iron Deficiency Anemia Nursing/Medical Treatment 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) Clinical Manifestations

Vitamin B12 Deficiency Anemia :

Aplastic Anemia-1051 : 

Aplastic Anemia-1051 Also known as Bone Marrow Depression Anemia Bone marrow fails to produce RBCs Cause is usually unknown, but usually related to toxin exposure (radiation/chemicals) or history of viral infection (HIV/Mono) Can occur alone, with leukopenia and thrombocytopenia, or all 3 (Pancytopenia) Clinical Manifestations Fatigue, Pallor, SOB, HA, Weakness, Tachycardia, CHF Treatment Blood Transfusions, Immunosuprressive Therapy/Steroids, Splenectomy, Bone Marrow Transplant
