By Jeanie Ward Iron Deficiency Anemia What is wrong? What causes Iron Deficiency Anemia in Children? Iron Deficiency Anemia Manifestations: Pallor; Pale mucus membranes Enlarged spleen and heart Poor muscle tone with decreased activity Fatigue Diagnosis low hemoglobin (<11g/100mL) Low hematocrit (<33%) RBC are small and hypochromic Serum iron levels are low ( 30μg/mL) Iron Deficiency Anemia Treatment Oral iron supplements What additional supplement should be give What is important to teach regarding diet? What foods high in iron? Sickle cell Disease What is wrong? What causes the cell to sickle? Low Oxygen tension (less than 60%-70%) Low blood pH (acidosis) Increased blood viscosity (dehydration, fever, hypoxia) Result of Sickling Process The sickled RBC’s do not move freely through the microcirculation. Blockage in vessel / blood flow halts Tissue distal to the blockage becomes ischemic Acute pain, cell destruction, tissue death Assessment General Manifestations Chronic anemia (Hgb. 6-9 g/dl.), pallor, weakness. Unable to do physical activities because of lack of stamina Fatigue, malaise Anorexia Jaundice Possible delayed sexual maturation Marked susceptibility to sepsis Possible growth retardation – with long bones disproportionately long. Types of Sickle Cell Crisis VasoOcclusive Aplastic Crisis Crisis Acute Sequestration Crisis Vaso-Occlusive Crisis Occurs from the pooling of many of the new sickled cells in vessels with resulting tissue hypoxia May last from one day to several weeks Manifestations of Vaso-Occlusive Crisis Bone Pain Most outstanding symptom Mainly in the bones of the extremities and joints, but can occur anywhere Abdominal and back pain is common Related to necrosis of bone tissue Parents may notice this with refusal to move an extremity, crying out with joint movement or joint touched. Hand and foot Syndrome Dactylitis Painful swelling of the hands and /or feet. May be the first symptom of crisis Warmth in affected areas. Fever Cerebrovascular accident Vaso-occlusion in the brain results in cerebral infarction which causes variable degrees of neurologic damage Hemiplegia Aphasia Seizures Vision changes Headaches Alterations in level of consciousness Acute Chest Syndrome Blockage of blood vessels in the chest leads to Pneumonia and acute chest syndrome Chest pains Fever, cough Dyspnea, retractions Leading cause of death in SCD. Priapism Persistent painful erection of the penis occurring when penile blood flow is obstructed. Hepatomegaly Enlarged liver with jaundice and hepatic coma. Hematuria related to damage to the kidneys Aplastic Crisis Diminished RBC production resulting in severe anemia Manifested by: Malaise, lethargy Headache Pallor fainting Aplastic Crisis Profound anemia- low RBC count is lifelong. The average RBC life is down to an average of 10-20 days in SCA. Jaundice, elevated bilirubin Reticulocytosis Bone marrow producing 3-4 times more RBC’s than normal Acute Sequestration Crisis Sickled cells become trapped in the spleen obstructing blood flow with pooling and enlargement of the spleen. Leads to shock and hypovolemia Circulatory collapse and death can occur in less than 30 minutes Spleen Function Acts as a filter against foreign organisms that infect the bloodstream. Filters out old RBC’s from the bloodstream and recycles them Minor Role: Manufacturers RBC’s toward end of fetal life and after birth, taken over by bone marrow. Acts as a blood reservoir. Spleen in the Infant Soft, purplish-red organ that lies under the diaphragm on the left side of the abdominal cavity Filters old blood and clears bacteria Teach Parents How to Measure Spleen A tongue depressor can be used to measure and track spleen size Place tip on left nipple and make mark where the spleen tip is felt Treatment for Sequestration Crisis Intravenous fluids Blood transfusion Spleen removal Effects of Chronic Crisis States on the Child’s Body Spleen – more susceptible to infection. Gradual fibrosis and scarring with reduction in spleen activity. Asplenia. Liver – enlarged, firm, tender Brain – single episode of sickling CVA, seizures Heart – enlarges and murmurs develop Lungs – pulmonary edema and stasis Kidneys – hematuria, unable to concentrate urine Bone Infarcts – hands and feet swell. Effects of Chronic Crisis States on the Child’s Body Eyes – bleeds in retina. Leg Ulcers Are seen in 10-15% of older children May start as simple insect bite or cut that does not heal With poor circulation develops into leg ulcer Treated with dressings, leg elevation and elastic stockings. Diagnostic Tests CBC – low hgb and hct Hemoglobin electrophoresis – used to determine type of hemoglobin. When you pass an electric charge through a solution of hemoglobin, distinct hemoglobins move different distances, depending on their composition. This technique differentiates between normal hemoglobin (A), Sickle hemoglobin (S). Goals in Care The is NO CURE for the disease Treat the Symptoms Relieve the pain Provide oxygenation Adequate hydration Pain Management Give analgesics as ordered Schedule nursing care to allow for optimal rest Position joints with pillows Application of warmth Promote circulation through passive ROM Oxygenation Assess Oxygen saturation- pulse oximetry. Should be 95% or >. Administer Oxygen for short period of time to keep saturation levels up. Bedrest to minimize energy expenditure and oxygen consumption Administer blood transfusions What are Complications associated with frequent blood transfusions? Allergic reaction Circulatory overload Iron Overload Give Desferal, an iron-chelating agent, to decrease the iron levels Oxygenation Prevent infection, dehydration Avoid emotional stress, overfatigue Avoid prolonged exposure to heat and cold Avoid low oxygen environment Hydration/ Electrolyte Replacement Encourage fluid intake, at least the minimum amount of fluid required daily for that child’s weight. (1-2x maintenance) Record I & O. Monitor electrolyte balance Give parents written instructions on specific amount of daily intake needed. Assess signs of dehydration (decreased urination, thirst) Teach parents measures to prevent dehydration such as avoiding heat / stress. Prevent Infection With the spleen damaged, has greater chance of getting sepsis. Avoid know sources of infection Assess Vital Signs and report elevated temperatures. Treat with Ibuprofen, NOT ASA. Place on prophylactic antibiotics such as Penicillin VK 250 mg twice a day, through age 5 yrs Prevent Infection Immunizations Hepatitis B series Pneumococcal Recipient of blood and blood products. Pneumovax for now at age 24 months and 5 years, with an improved vaccine coming on the market soon for administration to infants. Meningococcal vaccine H. influenzae vaccine Child / Parent Teaching Assess baseline knowledge and teach accordingly: Causes of disease and consequences, genetic counseling Situations that cause sickling Signs of developing crisis, infection, When to call the doctor Keep in school, promote normal g&d as much as possible Allow for decreased endurance - let the child set his or her own pace during strenuous exercise, and to take rest breaks when fatigue Explain some complications: CVA, anemia, swollen spleen, liver problems Support child and family Critical Thinking Which of the following nursing diagnoses should receive priority during a vasoocclusive crisis in a 14 year old with sickle cell anemia? A. B. C. D. Alteration in comfort Ineffective individual coping Decreased cardiac output Ineffective airway clearance Critical Thinking Which of these instructions should the parents of a child who has recovered from a sickle cell crisis receive? A B C D Isolate child from known sources of infection Avoid contact with all children Restrict child’s intake during the night Reinforce the basics of trait transmission Hemophilia What goes wrong? Who gets this? Do Hemophiliacs bleed more Profusely than people without Hemophilia? Hemophiliacs bleed mainly from minor cuts True or False Related to the deficiency of AHF Interviewing the Child with Hemophilia – Subjective Data Recent traumas and measures used to stop bleeding Length of time pressure was applied before bleeding subsided Was swelling increased after surface bleeding subsided Did swelling and stiffness occur without apparent trauma Assessment Prolonged bleeding anywhere from or in the body. When is it most often diagnosed? Assessment Surface bruising - Bleeding from trauma into soft tissues and muscles (the ileopsoas muscle around the hip, calf, forearm, upper arm, achilles tendon, buttocks, retroperitoneal. Hematuria Hemarthrosis - bleeding into joints (knees, elbows, ankles, shoulders, hips, wrists in descending order of frequency) Assessment CNS bleeding - Major cause of death Signs and Symptoms of CNS bleeds Persistent or increasing headache Repeated vomiting Sleepiness or a change in normal behavior Sudden weakness or clumsiness of an arm or leg Stiffness of the neck or complaints of pain with neck movement Complaints of seeing double The development of crossed eyes Poor balance when walking, a lack of coordination Convulsions or seizures Assessment of Child Bleeding in the mouth Hemarthrosis Surface bruising Diagnostic Tests DNA testing for the trait Blood Tests 1. Partial Thromboplastin Time (PTT) – Prolonged 2. Bleeding time – Prolonged > 2 hrs. 3. Platelet count and Prothrombin time – Normal 4. Low levels of Factor VIII Goals Prevent and control Bleeding Prevent crippling effects / Decrease pain Child/ Parent Teaching Interventions to Prevent or Control Bleeding What is the basic priority treatment to stop or prevent bleeding in people with hemophilia A? Why this is the priority? Additional Interventions to Prevent and Control Bleeding Administration of DDAVP (desmopressin acetate) nasal spray used to stimiulate release of factor VIII. Used with mild hemophilia Apply local pressure for 10-15 minutes Elevate joint above level of heart Apply cold compresses to promote vasoconstriction Prophylactic administration of factor VIII Interventions to Prevent Crippling effects / Decrease Pain During bleeding episode—elevate joint and immobilize ROM after acute episode Exercise unaffected joints and muscles. Give analgesics before Physical therapy. Do NOT give Aspirin. Watch diet/ weight – excessive weight stresses the joints What is the crippling Effect of Repeated bleeds into a Joint? Bleeding in joints, especially knees, ankles and elbows can lead to: loss of range of motion muscle loss destruction of the joints themselves Child / Parent Teaching Measures to prevent injury/ providing a safe environment Early recognition of bleeding episodes Keep current on immunizations Hepatitis B – because recipient of blood and blood products Child / Parent Teaching How to administer factor VIII. Children often learn how to infuse themselves at the age of eight or ten. Then, the hemophiliac is able to treat himself at home, at school, at camp or on vacation. Critical Thinking A 12 year old hemophiliac child has been admitted to the hospital for hemarthrosis. Which of these expected outcomes should receive priority in the child’s care? A. Family will receive genetic counseling B. Child will participate in appropriate activities for present condition C. Child and family will seek support from National Hemophilia Foundation D. Maximum function of the joint will be restored Review Following administration of factor VIII to a nine year old child admitted to the hospital with hemarthrosis, the nurse’s next action would be to: A. Elevate and immobilize the affected joint B. Institute passive range of motion to the affected joint during the acute phase C. Apply warm compresses to the affected joint D. Apply pressure to the area as needed Cancers Almost all childhood cancers involve blood or bloodforming tissues Leukemia Brain Tumors Lymphomas Neuroblastoma Wilms Rhabdomyosarcoma Retinoblastoma Othes Childhood Cancers Brain tumors – second leading cause of death from childhood cancer. Most are cerebellar and brain stem tumors Lymphomas Non-Hodgkins lymphomas—one-third present with a mass in the neck or mediastinal area. Also have dyspnea, wheezing, abdominal mass or pain and lymphadenopathy. Hodgkin’s disease – arises in single lymph node with painless nodal enlargement, followed by extension to adjacent nodes and into spleen, liver, lungs, bone marrow. Neuroblastoma – malignant tumor arising from sympathetic NS ganglion cells outside the cranium and and can arise from anywhere along the sympathetic nervous system chain. Can also occur in retroperitoneal area, pelvis, neck. Wilms Tumor – solid tumor of kidney. Rhabdomyosarcoma—malignant tumor of the striated muscle cells. occur in muscles around eye, head, neck, extremities, GU system. Retinoblastoma – intraocular malignancy of the retina of eye. Usually unilateral. If bilateral , hereditary. First sign is white pupil. Others – osteogenic sarcoma/ Ewings sarcoma – tumor of bones of the trunk. Often seen in adolescence growth spurt. Found in distal femur, proximal tibia. Warning Signs of Childhood Cancer C = continual unexplained weight loss H = headaches with vomiting (early morning) I = increased swelling of pain in joints L = lump or mass D = development of whitish appearance in pupil R = recurrent or persistent fevers, night sweats E = excessive bruising or bleeding N = noticeable paleness or tiredness Diagnostic Tests What is the major way cancer is diagnosed? What are additional tests? Blood Tests CBC Uric Acid Bone Marrow Aspiration PET, SPECT MRI, CT, ultrasound Interventions Radiation therapy Chemotherapy Surgery Bone Marrow and Stem cell transplantation Radiation Therapy Changes the DNA component of a cell nucleus The cell cannot replicate which Inhibits further cell division and growth Effects of Radiation Therapy Radiation sickness- anorexia, nausea, vomiting Fatigue Treated with antiemetics (Zofran or Anzimet). Cool cloth to forehead, provide distraction, accurate I&O. allow for naps an rest periods (coordinate care), encourage parent to cuddle in bed with child, pillow, blankets, favorite toys Skin reactions –erythema, tenderness Bone marrow suppression – anemia, neutropenia, thrombocytopenia Mucositis- inflammation of mucus membranes mainly the mouth May be on reverse isolation Offer soft foods, and cold foods. Frequent mouth care. Lidocaine oral to swish in mouth (older child) Long term – depends on part of body receiving radiation Chemotherapy There are several categories of antineoplastic drugs used in treating childhood cancers. Scheduled at set times and days and by different predetermined routes. May remain in hospital for few days at first, then later report on specific day for therapy. Children and Parents must be taught about what to do and not to do during therapy. Side effects and Toxic Reactions to Chemotherapy Bone Marrow Suppression – neutropenia, anemia, thrombocytopenia Place in reverse isolation, keep anyone exposed to a virus away from patient. Monitor temperature Should not receive live-virus vaccines Bleeding Tendency (thrombocytopenia) Apply pressure to puncture site No contact sports Check urine and stool for blood Give stool softeners. WHY? Soft objects in mouth Malaise and fatigue Nausea, vomiting, diarrhea, anorexia Encourage video games, movies, etc Allow visits from friends Give anti-emetics Small frequent meals Monitor for dehydration Altered mucous membranes Stomatitis Rectal ulcerations Side effects of chemotherapy Renal involvement Body Image changes Uric acid levels rise as a result of breakdown of cells. The renal tubules causing renal failure. If kidney affected/damaged- chemo drugs will not be excreted as usual and may limit drugs given. Alopecia Pain Review of Common Side Effects of Chemotherapy and Radiation Chemotherapy Bone marrow suppression Alopecia Malaise/fatigue Nausea Vomiting Anorexia Stomatitis Radiation side effects Skin reactions Fatigue Bone marrow suppression Nausea Vomiting Anorexia Mucositis Surgery Curative Remove the tumor and cancerous tissue Palliative Relieve complications due to the cancer Bone Marrow and Stem Cell Transplantation The goal of therapy is to administer a lethal dose of chemotherapy and radiation therapy that will kill the cancer and then re-supply the body with bone marrow and stem cells to reconstitute immunologic function. Healthy bone marrow or stem cells are infused into the bloodstream and migrate to the marrow space to replenish the patient’s immunologic function and help kill remaining cancer cells. Types of Transplantations Syngeneic Allogeneic bone marrow comes from identical twin bone marrow comes from matched sibling (one in four chances) or someone who is histocompatible. Autologous own bone marrow. May be harvested at time of remission in preparation for relapse or when bone marrow is free of malignant cells. Also being used so toxic doses of chemotherapy and radiation can be administered and the bone marrow rescued. Procedure First --All potential donors are typed for HLA (human leukocyte antigen) compatibility. Collection of bone marrow is a surgical procedure. The donor undergoes anesthesia for aspiration of the bone marrow The bone marrow is then processed and frozen When patient ready - it is infused into the recipient. Where is the most common site for bone marrow aspiration in children? Side effects of Transplantation 1. Graft-Versus-Host Disease (GVHD) – potentially lethal immunologic response of donor T cells against the tissue of the recipient. Signs and symptoms – rash, malaise, high fever, diarrhea, liver and spleen enlargement. Because there is no cure, prevention is essential. Careful tissue typing, irradiation of blood products which helps to inactivate mature T lymphocytes. 2. Rejection of the transplant Post Therapeutic Disabilities CNS – cognitive disorders, seizures, headaches, coordination problems Bone – asymmetric growth of bones, easy fractures, scoliosis, kyphosis CV – cardiomyopathy (pericardial thickening) , pericardial damage Respiratory – pneumonitis, pulmonary fibrosis GI – enteritis, bleeding, hepatic fibrosis Urinary – hemorrhagic cystitis, reflux Endocrine – decrease in growth, thyroid and gonadal dysfunction Reproductive – decrease sperm Dental - caries Secondary malignancies Ask Yourself? What is the most common form of childhood cancer? a. leukemia b. brain tumors c. lymphoma d.osteosarcoma How does that impact the body? The WBC's are produced so rapidly that immature cells (blast cells) are released into the circulation. These blast cells are nonfunctional, can't fight infection, and are formed continuously without respect to the body's needs The blasts cells then invade other organs and interfere with metabolism / function. The production of red blood cells and platelets decreases leading to anemia and thrombocytopenia. Leukemia Signs & Symptoms Bone marrow Depression results in: 1. 2. 3. 4. Decrease in mature WBC’s - fever Decrease RBC’s, Anemia- pallor, lethargy, anorexia Decreased Platelets/ thrombocytopenia- bleeding Increase cell metabolism which deprives cells of nutrients 5. Enlargement of organs infiltrated with blast cells results in: Bone pain Spleenomegaly. Hepatomegaly, Nephromegaly Lymphadenopathy CNS infiltration – increased ICP Diagnostic Tests History and Physical Blood Work Leukocytes are > 10,000 Platelet count, Hgb and Hct low Blast cells appear (where they normally don’t) Bone Marrow Aspiration Used to identify the type of WBC involved, therefore, type of leukemia X-rays of long bones Show lesions caused by invasion of abnormal cells Lumbar Puncture – blast cells in the CSF Chemotherapy A combination of antineoplastic drugs are given for about a month A different combination is given for about 2-3 years Advantages of using a combination of drugs: Decrease resistance to one drug Lessening of severe side effects of massive doses of one drug Breakdown of the tumor cell cycle at multiple sites Chemotherapy Phases 1. Remission induction- most intense treatment. Large doses of antineoplastic drug administered in an effort to destroy as many proliferating cells as possible. Lasts 4-6 wks. About 95% respond. 2. Consolidation- method of destroying leukemic cells in the CNS- for children who have CNS involvement or are high risk. Given Intrathecal. 3. Remission maintenance- drugs given at specific intervals. If remain in remission for 3 yrs, treatment is discontinued. Approx 80% of children who sustain remission for 2-3 yrs continue to remain in remission and appear to be cured. Administration of Chemotherapy When is intrathecal administration of chemotherapeutic medications required? Intrathecal chemotherapy is instilled in to the spinal canal for cancers that have metastasized to the brain What is the rationale for the use of cranial radiation in addition to chemotherapy? Nursing Care Prevent infection (neutropenia, anemia) Pain Relief Nausea and vomiting Mouth discomfort-mucositis / stomatitis Fatigue Alopecia Prevent blood loss-platelet low- nose bleed most common kind of bleed Support child and family Assist with referrals to social services, home health agency, chaplain Nursing Care Community Resource Candlelighters Childhood Cancer Foundation® (CCCF) is a national non-profit membership organization whose mission is to educate, support, serve, and advocate for families of children with cancer, survivors of childhood cancer, and the professionals who care for them. http://www.candlelighters.org/ American Cancer Society Make a wish Foundation Leukemia Society Church and Schools Tumor Lysis Syndrome p. 1325 Caused by the breakdown (lysis) of malignant cells which release intracellular contents into the blood. Intracellular electrolytes overload the kidneys and can lead to kidney failure. Further severe electrolyte imbalances cause metabolic acidosis, hyperkalemia, increase uric acid levels, hypocalcemia and cardiac arrythmias. Tumor Lysis Syndrome PREVENTION Hydrate with IV fluids containing bicarbonate which alkalinizes the urine preventing formation of uric acid crystals which damage the kidney Treatment Treat with IV fluids, electrolyte replacement, allopurinol. An embryonic tumor of the kidney. Etiology and Pathophysiology Cause is unknown Originates from immature renoblast cells Tumor is vascular Assessment Palpable abdominal mass Firm and smooth **The abdomen should not be palpated once the diagnosis is made. Avoid palpating the tumor mass during assessment because of the risk of rupturing the protective capsule. Excessive manipulation can cause seeding of the tumor and spread of cancerous cells Abdominal distention Fever Fatigue Late signs Anemia Hematuria, dysuria Hypertension Diagnostic Tests Abdominal ultrasound CT, MRI Biopsy Interventions Nephrectomy and removal of lymph nodes Post-op chemotherapy and / or radiation therapy CT every 6 months for 3 years Chest x-ray every 3 months for 3 years Nursing Care Pre-op Sign on bed ”Do Not Palpate Abdomen” Child / Parent teaching Post-op Monitor kidney function, Strict I & O Monitor vital signs—B/P and temperature Monitor GI function– assess bowel sounds and stool production NG tube to drainage. Measure abdominal girth. Caring for a child who is dying can be one of the hardest tasks in nursing Understanding of Death Children under 3 Have no understanding of own impending death May perceive family anxiety, sadness Preschool to 5 years More afraid of separation from parents than of thought of dying. Greatest fear is separation. Envision death as temporary, and have little of adults’ fear of it Think of it as a long sleep, not a final process. Nightmares increase. May feel pain / illness is a punishment for misdeeds or thoughts May ask questions about death In long term illness – may simulate adult response with depression, withdrawal, fearfulness, anxiety School Age 5-9 Begin to understand that death is permanent May think it is something that only happens to adults Become aware of what is happening to them when their disorder has a fatal prognosis. Concerns center around fear of pain, fear of being left alone and leaving parents and friends. May associate death with sleep and may be afraid to go to sleep without someone near them. May associate death with darkness—want light left on in room Understanding Death Adolescent, older school age By age 10 have an adults concept of death, realizing that it is inevitable, universal, and irreversible. Have more understanding than adults realize. Understand that death is the cessation of life. Emotional outbursts may reflect anger View death as fearsome and fascinating (increase in adolescent suicide). May feel immune to death and deny symptoms for longer than usual because they believe it is impossible that anything serious could happen to them. Some adolescents consider themselves alienated from their peers and unable to communicate with their parents for emotional support feeling alone in their struggle. Nursing Care Child 1. 2. 3. 4. 5. 6. Elicit child's understanding of death before discussing Encourage children to express feelings in own way through play, drawings, or verbalization to promote free expression. Provide a safe, acceptable outlet for expressions of feelings Structure care of child to allow child choices and participation in process within constraints of physical condition Help child maintain independence and control; normal ADL as much as possible (set realistic goals) Realize that they will go through the stages of dying: denial, bargaining, anger, depression, acceptance Nursing Care Parents 1. 2. 3. 4. Spend time with family to listen, answer questions, and provide information. Discuss issues with parents before discussing with child. Provide opportunities for family to express their emotions and deal with their feelings. Parental reactions: continuum of grief process and usually depend on previous experiences with loss, intellectualization. Reactions may depend on relationship with child and circumstances of illness or injury Reactions depend on degree of guilt felt by parents-help them sort out 5. 6. 7. 8. Assist parents in expressing fears, concerns, grief to enable them to appropriately support child Assist parents to understand sibling' possible reactions to terminally ill child · Guilt- believing they caused the problem or illness · Jealousy- wanting equal attention from parents · Anger- feelings of being left behind Support, enhance parent-child communication, enhance parents' ability to support child Refer to parent, family support groups- not alone, help focus, open communication, provide information Nursing Care Nurse Nurse needs to care for self. Care of the caregiver is imperative if the nurse is to provide physical and psychosocial care for families at such a difficult time. Caring for dying children and their families can be stressful and emotionally demanding.
