    Study Notes

    Causes of Neonatal Anemia

    • Blood Loss (Hypovolemia) - Can occur before, during, or after birth.

      • Prenatal: Placenta-related complications like placenta previa or abruptio placentae, cord malformations, and certain diagnostic procedures can lead to bleeding.
      • Perinatal: Precipitous birth can result in umbilical cord bleeding, birth trauma to the cranium (subgaleal bleed), or damage to abdominal organs.
      • Postpartum: Hypoxia, shock, or even death from a subgaleal bleed can contribute to anemia.

    • Decreased Red Blood Cell (RBC) Production

      • Congenital Defects: Rare conditions like Fanconi anemia and Diamond-Blackfan anemia can cause decreased RBC production.
      • Acquired Defects: Infections like rubella, syphilis, HIV, and bacterial sepsis can impair bone marrow function.
      • Nutritional Deficiency: Deficiencies in vitamins B12, folate, vitamin E, or iron are uncommon at birth, but can contribute to anemia.

    • Excessive RBC Hemolysis

      • Blood Group Incompatibilities or RBC Disorders: Conditions such as G6PD deficiency (most common), hemoglobinopathies, and infections can cause increased breakdown of RBCs.

    • Physiologic Anemia of the Newborn

      • Considered a normal physiological process.
      • Increased oxygenation after birth leads to a decrease in erythropoiesis.
      • The combination of decreased erythropoiesis and shorter lifespan of neonatal RBCs causes a drop in hemoglobin within the first 6-12 weeks. This stabilizes as erythropoietin production and bone marrow activity increase.

    Causes of Neonatal Anemia

    • Hypovolemia (Blood Loss)

      • Prenatal: Placental bleeding, cord malformations, diagnostic procedures like amniocentesis
      • Perinatal: Precipitous delivery, birth trauma with cranial bleeds or abdominal organ damage
      • Postpartum: Hypoxia, shock, or death from subgaleal bleeds

    • Decreased RBC Production

      • Congenital Defects: Fanconi anemia, Diamond-Blackfan anemia
      • Acquired Defects: Infections (rubella, syphilis, HIV, bacterial sepsis) can impair bone marrow function
      • Nutritional Deficiency: Deficiencies in B12, folate, vitamin E, or iron are uncommon at birth

    • Excessive RBC Hemolysis

      • Blood Group Incompatibilities: Rh incompatibility, ABO incompatibility
      • RBC Disorders: G6PD deficiency (most common), hemoglobinopathies, infections

    • Physiologic Anemia of the Newborn

      • Occurs due to increased oxygenation following birth, reducing erythropoiesis
      • Hemoglobin levels drop over the first 6-12 weeks due to decreased erythropoiesis and shorter lifespan of neonatal RBCs
      • Erythropoietin stimulation and increased bone marrow activity stabilize hemoglobin levels

    Infant and Children Iron Deficiency

    • Infants between 4-6 months have an increased iron demand due to rapid growth.
    • Another surge in iron demand occurs between 1 and 6 years of age.
    • Excessive cow's milk intake exceeding 24 ounces per day or introduction before 12 months can contribute to iron deficiency.
    • Prolonged breastfeeding without iron supplementation can also lead to iron deficiency in infants.
    • Iron deficiency in infants and children can cause mental and motor development deficits, which may have long-lasting effects.
    • Parents should provide a balanced diet with iron-rich foods and limit cow's milk consumption in children.

    Adolescent Iron Deficiency

    • Adolescents have increased iron needs due to high metabolic needs, blood volume expansion, and increased muscle mass.
    • Heavy menstrual bleeding in girls may require hormone regulation to manage iron levels.
    • Underweight, malnourished, overweight, or obese adolescents are at a higher risk of iron deficiency.
    • Obese girls have a higher risk of iron deficiency compared to obese boys.
    • Adolescent athletes, particularly endurance trainers, and those on restrictive diets are also vulnerable to iron deficiency.
    • Education should focus on encouraging a diet rich in iron to meet the increased needs of adolescents.
    • Increased plasma volume dilutes red blood cells (RBCs) during pregnancy.
    • Rapid placental and fetal growth significantly increases iron requirements.
    • Iron deficiency anemia is a major concern during pregnancy.

    Adverse Outcomes of Anemia in Pregnancy

    • Maternal and perinatal mortality rates increase.
    • Preterm delivery and low birth weight are more common.

    Reproductive-Age Women Risk Factors for Anemia

    • Heavy menstrual bleeding, uterine fibroids, vegetarian diets, and childbirth-related blood loss increase anemia risk.

    Common Causes of Anemia in Older Adults

    • Iron deficiency due to poor dietary intake or malabsorption is common.
    • Chronic diseases like inflammation and chronic kidney disease contribute to anemia.
    • Bone marrow responsiveness declines with age, affecting RBC production.
    • Some medications have side effects that suppress bone marrow function, leading to anemia.

    Impact of Anemia on Health in Older Adults

    • Anemia causes increased fatigue, shortness of breath (dyspnea), confusion, and impaired mobility.
    • Higher risk of hospitalization, mortality, and reduced ability to perform activities of daily living (ADLs).
    • Mortality risk is magnified for older adults with chronic renal or cardiac disease.

    At-Risk Populations for Anemia in Older Adults

    • African American older adults are more susceptible to anemia compared to other demographics.

    Interventions for Anemia in Older Adults

    • Dietary education emphasizes iron-rich foods.
    • Referral to community services like Meals on Wheels provides support.

    Screening and Acute Care

    • Early detection is crucial for timely intervention and preventing complications.
    • Oxygen administration and IV fluid administration are essential acute care measures during crises.

    Long-Term Care

    • The aim is to prevent complications and optimize overall health and well-being.
    • Self-care management through dietary counseling and extensive patient education play a vital role.

    Assessment

    • Observation & Patient Interview

      • Observe for signs like pallor in skin and mucous membranes, cheilosis (mouth corner fissures), easy bruising or bleeding, loss of balance, and dyspnea (shortness of breath) during exertion.
      • Inquire about subjective symptoms like SOB, fatigue, weakness, dizziness, palpitations, history of anemia or bleeding, menstrual history, current medications, chronic illnesses, usual diet, alcohol, and smoking habits.

    • Physical Examination

      • Vital signs assessment: Temperature, Blood Pressure, Heart Rate, and Respiratory Rate.
      • Skin & Mucosa: Observe color and any signs of pallor.
      • Lungs & Heart: Auscultate breath sounds and palpate apical pulse.
      • Circulation: Check peripheral pulses and capillary refill time.
      • Abdomen: Assess for tenderness, signs of bleeding or bruising.

    Screening and Acute Care

    • Early detection is key to promoting intervention and preventing complications.
    • Oxygen administration and IV fluid administration are critical during acute crises.

    Long-term Care

    • The goal is to prevent complications, optimize health and wellness.
