Health Problems of Infants Study Guide

Learning Objectives for Infant Health Problems

• Food Sensitivity Teaching Plan: Develop a comprehensive teaching plan for parents regarding infants with food sensitivities.

• Failure to Thrive (FTT) Care Plan: Develop a plan of care for parents of children experiencing growth faltering or failure to thrive.

• Special Health Problems Teaching Plan: Create educational strategies for parents dealing with specific infant issues including:

  • Colic.

  • Sleeping problems.

  • Sudden Infant Death Syndrome (SIDS).

  • Apparent Life-Threatening Events (ALTE).

• Post-SIDS Nursing Care: Describe the specific nursing care and support required for a family following a SIDS event.

Infant Food Sensitivity

• Food Allergy: Defined as an adverse immunologic physiologic reaction to food.

  • Mechanism: Typically an Immunoglobulin E (IgE)-mediated immune response.

  • Example: Cow’s milk allergy.

• Food Intolerance: Occurs when the body is unable to digest a specific food.

  • Mechanism: A non-IgE-mediated immune response.

  • Example: Lactose intolerance.

• Sensitization: The process where an initial exposure results in a mild first reaction, followed by significantly stronger and more severe immune responses in future encounters.

• Common High-Allergy Foods:

  • Eggs.

  • Nuts.

  • Fish.

  • Milk.

  • Wheat.

Nursing Management of Food Sensitivities

• Assessment: Identify potential triggers and reactions.

• Education for Key Stakeholders:

  • Family members.

  • School personnel.

• Content of Education:

  • Signs and symptoms of allergic reactions.

  • Proper administration of Epinephrine (EpiPen).

Cow's Milk Allergy (CMA)

• Prevalence: Approximately $2.5\%$ of infants develop a hypersensitivity to cow’s milk.

• Clinical Manifestations:

  • Gastrointestinal: Diarrhea, vomiting, Gastroesophageal Reflux Disease (GERD), loose stools, and the presence of occult blood in stools.

  • Respiratory: Rhinitis, bronchitis, asthma, sneezing, and coughing.

  • Cutaneous: Urticaria (hives) and atopic dermatitis.

  • Systemic/Severe: Anaphylaxis and growth failure.

• Diagnostic Tools:

  • Comprehensive health history.

  • Skin-prick testing.

  • Testing for occult blood in the stool.

  • Challenge testing (controlled reintroduction).

• Therapeutic Management:

  • Switching to casein hydrolysate milk formulas.

  • Utilizing amino acid-based formulas.

• Nursing Management:

  • Extensive education regarding dietary changes.

  • Teaching parents how to read and interpret food labels for hidden milk proteins.

Growth Faltering and Failure to Thrive (FTT)

• Definition: Inadequate growth resulting from an inability to obtain or use the calories required for development.

• Pathophysiology Categories:

  • Inadequate Caloric Intake: Not enough energy being consumed.

  • Inadequate Absorption: Body is unable to take in nutrients (e.g., malabsorption syndromes).

  • Increased Metabolism/Excessive Expenditure: The body burns calories faster than they are replaced.

  • Defective Utilization: Genetic or metabolic disorders preventing the body from using nutrients properly.

• Diagnostic Evaluation:

  • Review of growth charts (plotting height/weight over time).

  • Detailed health history.

  • Comprehensive dietary history.

  • Physical examination.

  • Developmental assessment.

  • Family assessment (social and environmental factors).

Therapeutic Management of FTT

• Primary Goal: Address the underlying cause of the growth failure.

• Specific Goals:

  • Correct any nutritional deficiencies.

  • Achieve an ideal weight for the infant.

  • Support "catch-up growth."

  • Educate parents on nutritional needs and feeding techniques.

• Feeding Strategies for Infants with FTT:

  • Core Staff: Use a consistent group of caregivers to build rapport and observe patterns.

  • Environment: Reduce stimulation and provide a calm atmosphere for feedings.

  • Persistence: The caregiver must be persistent in offering food.

  • Interaction: Maintain face-to-face interaction during feeding.

  • Structure: Develop and maintain a highly structured routine.

  • Age Considerations: Tailor strategies for toddlers and preschoolers as they age.

Colic: Paroxysmal Abdominal Pain

• Definition/Criteria (The Rule of 3s):

  • Crying for more than $3$ hours per day.

  • Crying occurs more than $3$ days per week.

  • Crying persists for more than $3$ weeks.

• Key Indicator: The child continues to gain weight and thrive despite the crying episodes.

• Management:

  • Rule out other medical causes for the pain or crying.

  • Medications: May include antispasmodics, antihistamines, or antiflatulents (e.g., simethicone).

• The "5 S's" for Soothing:

  • Swaddling: Snug wrapping of the infant.

  • Side/Stomach Holding: Positioning the baby on their side or stomach while being held (never for sleep).

  • Soothing Noises: Utilizing shushing or white noise machines.

  • Swinging/Slow Movement: Providing rhythmic motion.

  • Sucking: Offering a pacifier.

Sleeping Problems in Infants

• Classification:

  • Dyssomnias: Primary disorders of initiating or maintaining sleep.

  • Parasomnias: Abnormal behaviors occurring during sleep.

• Common Specific Issues:

  • Nighttime feeding habits.

  • Developmental night crying.

  • Refusal to go to sleep.

  • Trained night crying (infant expects a certain comfort to return to sleep).

• Nursing Management:

  • Assess the existing sleep pattern.

  • Educate parents on "graduated extinction" (gradually increasing the time before responding to crying).

  • Establish and maintain a consistent sleep routine.

Sudden Infant Death Syndrome (SIDS)

• Definition: The unexplained, sudden death of an infant under $1$ year of age. Diagnosis is made after a postmortem examination, death scene investigation, and review of case history.

• Epidemiology: SIDS is the $3^{rd}$ leading cause of infant death.

• Possible Etiology: Potential brainstem abnormality in the neurological regulation of cardio-respiratory control.

• Risk Factors:

  • Maternal smoking.

  • Co-sleeping (sharing a bed with an adult or sibling).

  • Prolonged QT interval in the infant.

  • Soft bedding (pillows, quilts, bumper pads).

  • Prone (belly) sleep position.

  • Infant-specific factors: Low birth weight, recent illness, male gender, family history of SIDS.

Risk Reduction for SIDS

• Sleep Position: Always place infants in the supine (back) position for sleep.

• Supervised Activity: Encourage "tummy time" while the infant is awake and monitored to build neck/shoulder strength.

• Sleep Surface: Use a firm sleep surface.

• Environment: No loose bedding, toys, or soft objects in the crib.

• Bed Sharing: Avoid co-sleeping.

• Feeding: Encourage breastfeeding.

• Climate: Do not overheat the infant with too many layers.

Comparative Risks: Belly-Sleep vs. Back-Sleep

• Critical Data: Belly-sleep carries up to $13$ times the risk of sudden death compared to back-sleep.

• Comparison Matrix:

  • Cries more: Found in Back-sleep.

  • Wakes more: Found in Back-sleep (protective mechanism).

  • Harder to arouse: Found in Stomach-sleep (higher risk).

  • Likely to overheat: Found in Stomach-sleep.

  • Re-breathing/Increased $CO_2$: Found in Stomach-sleep.

  • More Apnea: Found in Stomach-sleep.

  • Spitting up/Choking: Risk is the SAME for both positions.

  • Greater risk of sleep-related death: Found in Stomach-sleep.

Caring for the Family Following SIDS

• Emotional Support: Provide compassionate, non-judgmental care.

• Final Moments: Facilitate the family's ability to say goodbye to the infant.

• Psychosocial Considerations: Address intense feelings of blaming and guilt within the family unit.

Apparent Life-Threatening Event (ALTE)

• Definition: An episode that is frightening to the observer (parent/caregiver) where they report the infant stopped breathing, turned blue/purple, or "almost died."

• Clinical Significance: Considered a "near-miss" SIDS event.

• Risk Factors: Approximately $30\%$ of ALTE infants were born at less than $37$ weeks gestation.

• Symptoms Observed:

  • Apnea (cessation of breathing).

  • Color change: Cyanosis (blue/purple) or pallor (pale).

  • Muscle tone change (limpness or rigidity).

  • Choking, gagging, or coughing.

• Required Interventions:

  • Significant intervention is often required to restore normal breathing.

  • The infant is monitored in the hospital setting.

  • Parents may be sent home with apnea monitors.

  • Strong recommendation for parents to attend Infant CPR classes.

Safe Sleep ABCs

• A - ALONE: Place the baby alone in the crib to sleep; no pillows, blankets, or people.

• B - BACK: Always place the baby on their back for every sleep period (naps and night).

• C - CRIB: Use a firm, flat mattress with a fitted sheet. Keep the crib entirely empty of objects.
