Anemia’s Reduction of: number of red blood cells
the quantity of hemoglobin the volume of packed red Iron-Deficiency Anemia Sickle Cell Anemia Beta-Thalasemia Major (Cooley’s anemia )

Iron Deficiency Anemia

Iron-Deficiency Anemia
A nutrient deficiency of inadequate dietary iron The most common hematologic disorder of infancy and childhood Peaks at 9 months- 2 years, adolescence Prevented by use of iron fortified productsn

Children at Risk low birth weight infants
infants born to mothers with iron deficiency anemia infants born with GI defects chronic blood loss in older children

Pathophysiology Dietary Fe is bloodstream binds to transferrin (TIBC) and is delivered to RBC in bone Marrow, combines with other cells to make Hgb Unused dietary Fe is stored in intestinal epithelial cells as ferritin

History Dietary history usually shows abnormally high milk intake > 32 oz day in toddler Ask parents specific questions Begin the dietary history at the time the child awoke yesterday; include all activities and exactly what the child ate

Diagnosis Low RBC Low HGB Low HCT Low Iron High Transferrin (TIBC)
Mild ( < 10.2), Moderate (8-9), Severe (< 7) Low HCT Low Iron High Transferrin (TIBC) Low Ferritin

Symptoms Low Hgb=low O2 tissue perfusion Hgb of 10.2 or less
May seem asymptomatic, not noticed by caregiver Pallor/Pale mucous membranes (low hgb, not enough red color to skin) Poor muscle tone, decreased activity Fatigue Increased HR, RR Hgb < 9 Above symptoms plus irritability, lack of interest in play

Nursing Considerations
Consume Iron-fortified formula Limit cow’s milk to oz/day for children >12 months Increase age-appropriate iron-rich foods and Vit C May be ordered to take Fe supplements- Ferrous Sulfate

Iron-Rich Foods Vitamin C Rich Foods Meats, fish, poultry Orange juice Vegetables Citrus fruits Dried fruits Strawberries Legumes Tomatoes Enriched grain products Broccoli Whole grain cereal Leafy Green vegetables Iron-Fortified Cereal Potatoes

Manage side effects of Ferrous Sulfate Nausea, Anorexia Constipation Abdominal distress Black stools. Give on an empty stomach if possible Monitor bowel movements and suggest increased fluid and fiber.

Monitor development, sleep, and activity/fatigue patterns Monitor hemoglobin to measure effectiveness of therapy Instruct families to keep Ferrous Sulfate locked and out of reach of children; poisoning is a serious risk

Sickle Cell Anemia

Sickle Cell Anemia Autosomal recessive disorder
Seen in African Americans Characterized by abnormal hemoglobin (HbS) Clinical manifestations caused by obstructions due to the sickled RBC’s and destruction of sickled and normal RBC’s

Sickle Cell Anemia Can be diagnosed in-utero
Symptoms may not appear until 6 months of age Mortality rate children < 3 years old is 35%

Signs and Symptoms Pallor Fatigue SOB Irritability Jaundice

Diagnosis Moderately low Hcb and Hct Normal Iron, TIBC, Ferritin
Elevated Billirubin

3 Complications of Sickle Cell Anemia
Vaso-Occlusive Crisis Acute Chest Syndrome Splenic Sequestration

Vaso-occlusive crisis
Severe, sudden onset of sickling where many new sickled cells pool in a vessel and cause pain and tissue hypoxia Caused by: infection, dehydration, anxiety, cold Most common from hypoxia secondary to rapidly destroyed RBC Lasts for hours to weeks

Vaso-occlusive Crisis
Early Signs fever tachycardia pallor Late Signs abdominal pain back pain extremity pain First Crisis in infants Dactylitis (hand & foot syndrome) swelling of hands and feet joints may be warm & swollen

Prevent/Treat occulsions Adequate oxygenation
Management Pain relief Prevent/Treat occulsions Adequate oxygenation

Pain Assess pain every 1-2h or more frequently
Use pain scale appropriate for age Non-pharmacological pain methods AROUND THE CLOCK PAIN MEDS Tylenol for mild pain Narcotics for mod-severe pain

Hydration Prevents and treats occlusion Push PO fluids
IV hydration 1.5 to 2 times normal rate Risk for fluid overload Listen for crackles

Treat Sickling-Oxygenation
Administer oxygen Maintain saturation of 95% or higher Semi-fowler’s position

Acute Chest Syndrome Sickle contents break off
Bilateral pulmonary involvement Causes chest infection, embolism

Symptoms Chest pain Fever Cough Wheeze Tachypnea Analgesics Oxygen Hydration Incentive spirometry Antibiotics PRBC

Splenic Sequestration
Sickled cells block the spleen Blood pools in spleen and/or liver and enlarges Pooled blood leads to a decrease in circulating volume Can lead to hypovolemic shock

Symptoms Irritability Pale Tachycardia Pain to LUQ Enlarged Spleen Life Threatening- get child to ED a.s.a.p.! PRBC Remove spleen

Post-Splenectomy Risk for Infection r/t Chronic Immunosuppression
Administer PCN everyday Up-to-date vaccines Educate parents Signs of infection & respiratory distress possible triggers treat pain immediately adequate fluids

Beta-Thalasemia Major
(Cooley’s Anemia)

Beta-Thalasemia Major (Cooley’s anemia)
Hereditary anemia due to abnormal synthesis of hemoglobin Life long disorder Mediterranean descent Life threatening symptoms

Diagnosis Low RBC’s Extremely low Hgb < 5 Increased serum iron

Symptoms Facial anomalies
Frontal bossing (prominent and protruding forehead) Maxillary prominence Wide-set eyes with a flattened nose Bronze skin color (Greenish yellow skin tone) Growth and maturation retardation

Management: RBC transfusions q 2-4 weeks Iron Chelation therapy
Desferal (deferoxamine) SQ Splenectomy Cure isbone marrow stem cell transplant Estimated 70% do not find a suitable donor

Observe for complications of transfusion- iron overload Supporting the child and family in dealing with a chronic life-threatening illness Monitor Growth and Development Refer the family for genetic counseling

Compare and Contrast Iron Deficiency Sickle Cell Thalasemia Low RBC’s
Low HCT Low Hgb Low iron Low ferritin High TIBC Mod low Hgb Normal iron Normal ferritin Normal TIBC Inc Bilirubin Very low Hgb Increased iron

Bleeding Disorders

Clotting Host of factors Platelets aggregation at site of injury
Tested by coagulation time (PT/PTT)

Types of Bleeding Disorders
Hemophilia A Von Willebrand’s Disease ITP (Immune Thrombocytopenic Pupura)

Hemophilia A

Hemophilia A Hereditary blood coagulation deficiency (factor 8)
Ability to clot is slower X-linked recessive (white, males)

If Suspected ask about Recent traumas and measures used to stop bleeding Length of time pressure was applied before bleeding subsided Whether swelling increased after surface bleeding subsided Whether swelling and stiffness occurred without apparent trauma

Diagnosis Above History Suspected by Labs:
Platelet level: Normal PTT: Prolonged (elevated number) > 60 Confirmed by genetic testing for missing factor

Symptoms Vary according to concentration of factor 8
Soft tissue bleeding and painful hemorrhage into joints Severe bleeding may occur in GI tract, peritoneum or CNS

Management of Bleeding
Acute therapy Acute bleeding stopped by IV administration of factor 8 Pressure to laceration Prophylactic therapy PO factor 8 replacement on a regular schedule if frequently symptomatic (prior to surgery, dental work)

Parental Education Primary Goal is Injury Prevention
Promote oral hygiene, up to date immunizations No aspirin Avoid activities that induce bleeding Provide activities for normal G&D Administration of factor replacement prn

Von Willebrand’s Disease

Von Willebrand’s Disease
Most commonly inherited bleeding disorder, autosomal dominant (Males and Females) Lacks production of VWF Platelets are normal in number Inability of platelets to aggregate Varying degrees of disease VWF is deficient to defective

Diagnosis Platelets is normal PT/PTT is normal
Confirmed by genetic testing for VWF

Can be so mild that disease is undiagnosed
Signs & Symptoms Can be so mild that disease is undiagnosed Bleeding from gums Epitaxis Prolonged bleeding from cuts Excessive bleeding following surgery

Management Primary Goal: Injury Prevention Prophylactic therapy
Replace dysfunctional factor in blood when bleeding with DDAVP

ITP (Immune Thrombocytopenic Pupura)

ITP Autoimmune disorder (antiplatelet antibody) or cause is unknown (idiopathic) Occurs most commonly at age 2-4 years Reduction in and destruction of platelets Typically seen 2 weeks after a febrile, viral illness

Signs and Symptoms Excessive bruising and petechiae Epitaxis
Bleeding into joints Tourniquet test: shows many petechiae after inflation of BP cuff

Diagnosis Platelets < 150 (Marked thrombocytopenia)
PT and PTT is Normal

Management PLT transfusion (only a temporary solution)
Injury Prevention Avoid when possible: administering intramuscular injections aspirin, aspirin-containing products, and nonsteroidal antiinflammatory medications (e.g., ibuprofen) taking temperatures rectally

Compare and Contrast Hemophilia A VWF ITP Normal Platelets
Elevated PT/PTT Normal PT/PTT Very Low Platelets

Oncology

Oncology Cancer in adults Cancer in children
abnormal cell is transformed by genetic mutation of its DNA usually as a result from exposure to a tetragon Cancer in children usually arises from chromosomal abnormalities, genetic mutations and proliferation of embryonic cells

Oncology Treatment Surgical intervention
Removing the entire cancerous tumor Most ideal and frequently used treatment method

Oncology Treatment destroy tumor cells by cause cell death
Chemotherapy destroy tumor cells by cause cell death normal cells that have rapid growth are also affected, such as hair growth toxic side effects

Oncology Treatment Radiation therapy
Least preferred treatment in children Interrupt cellular growth by breaking the DNA stands, leading to cell death

Types of Cancer in Children
Small percentage Carcinoma (opposed to large percentage in adults) Mostly Leukemia Followed by Lymphoma The rest is solid or soft tissue tumors

Clinical Manifestations
Differ based on type of cancer Many symptoms are similar to common childhood illnesses Symptoms may be in site other than the cancer =delay in diagnosis Often diagnosis made when cancer is advanced

Common Clinical Manifestations
Pain Anemia Anorexia, weight loss Infections Bruising Neurological symptoms Palpable mass

Psychosocial Concerns
Parents in disbelief Health child suddenly becomes ill Potentially life-threatening Treatment decisions, can last months-years Travel for treatment, heavy financial responsibilities Effects of siblings

Effects on Child Infants- unaware of diagnosis
Toddlers- aware they do not feel well Preschoolers-beginning understanding of illness, not cancer School-age-understand cancer, benefit from talking about it Adolescents-mature understanding, benefits from other adolescents with cancer

General Nursing Considerations
Provide optimal nutrition- high metabolic rate of cancer depletes stores Ensure adequate hydration-ice pops, jello Manage pain Promote growth and development Prevent Infection (next slide)

Risk for infection r/t Immunosuppressed state.
Monitor vital signs q4h Instruct parents how to measure temp at home Proper handwashing Inspect child’s skin for breakdown Inspect child’s mouth for ulcers Teach child and parents meticulous oral hygiene No live virus administration

Leukemia

Leukemia Broad term describing a group of malignant diseases
Normal bone marrow is replaced by abnormal immature cells Develops from a variety of agents thought to increase risk (virus, toxins, drugs) combined with genetics

Acute Lymphocytic Leukemia
Occurs in children< 15 years old (peak 2-6 years old) Distorted and uncontrolled proliferation of immature WBC’s (lymphoblasts) Causes decreased RBC’s, platelets, and mature WBC’s production Invasion of body organs by rapidly increasing lymphoblasts

Signs and Symptoms Fever Bone or joint pain Bruising Lymphadenopathy
CBC Changes Physical Exam Fever Bone or joint pain Bruising Lymphadenopathy Hepatosplenomegaly Decreased RBCs Decreased PLTs Very high WBC

Diagnosis Signs & symptoms CBC changes
Confirmed with bone marrow aspiration (> 25% of lymphoblast cells present)

Management High dose chemotherapy administered for 2-3 years
Returns blast cells in bone marrow to less than 5% Physical assessment findings are normal

Tumor Lysis Syndrome Metabolic emergency
Lysis (dissolving or decomposing) of tumor cells Rapid release of their contents into the blood

Tumor lysis syndrome Rapid cell destruction releases high levels of
uric acid potassium phosphates Uric acid overloads the kidneys Leads to cardiac arrhythmias and renal failure

Children receiving chemotherapy monitor for Hyperuricemia Hyperkalemia Hyperphosphatemia Hypocalcemia

Administer vigorous hydration (2–4 times rate for maintenance fluid) Administer allopurinol or urate oxidase (rasburicase) Reduce conversion of metabolic by-products to uric acid

Care of the Chronically Ill Child

Chronically Ill Child Nursing Diagnosis
Fear Death Anxiety Anticipatory Grieving Hopelessness

Goals for Care of the Chronically Ill Child
Goals for the child Achieve and maintain normalization Obtain the highest level of health and function possible Goals for the family Remain intact Maximize function throughout the illness

Nursing Care for Children with Chronic Conditions and Their Families
Attend to the needs of the family system Revise goals frequently to meet the child’s changing developmental needs Listen carefully to the child's perception of the condition

Nursing Care for the Dying Child and the Child’s Family
Be available to assist both child and family Avoid imposing personal beliefs and expectations Provide time and attention to the dying child Recognize the need to talk about illness and death Provide adequate pain control, oral care, privacy, and information about the signs of imminent death After death, allow family members as much time as they desire with the child

Practice Questions!
