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.
Pregnancy-Related Causes of Anemia
- 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.
- Focus on self-care through dietary counseling and patient education.
Assessment: Observation and Patient Interview
- Look for pallor (skin and mucous membranes), cheilosis (fissures at mouth corners), bruising/bleeding, loss of balance, and dyspnea on exertion.
- Ask about shortness of breath (SOB), fatigue, weakness, dizziness, palpitations, anemia or bleeding history, menstrual history, current medications, chronic illnesses, usual diet, alcohol, and smoking patterns.
Physical Examination
- Vital signs: Assess temperature, blood pressure, heart rate, and respiratory rate.
- Skin & Mucosa: Observe color and signs of pallor.
- Lungs & Heart: Auscultate breath sounds and palpate apical pulse.
- Circulation: Assess peripheral pulses and capillary refill time.
- Abdomen: Examine for tenderness, bleeding or bruising.
Implementation
- Symptom Management: Prioritize life-threatening physiologic needs over pain management.
- Pain Management: Administer analgesics routinely based on patient's culture, preferences, and symptoms.
-
Promote Cardiorespiratory Function: Monitor vital signs, breath sounds, and apical pulse.
- Watch for abnormal signs like increased blood flow leading to murmurs, S3/S4 sounds, tachypnea, and dyspnea.
- Report signs of decreased cardiac output to the physician as severe anemia can lead to heart failure.
-
Assess:
