Study Notes
Mechanisms of Heat Loss
- Heat loss in infants occurs through conduction, convection, evaporation, and radiation.
- Conduction involves heat transfer when cooler solid objects are in contact with the body.
- Convection describes heat loss from the body's surface to cooler surrounding air.
- Evaporation occurs when liquid (e.g., sweat) converts to vapor, leading to cooling.
- Radiation transfers heat from the body to cooler solid objects not in direct contact.
Care of Newborn in the Delivery Room
- Maintaining an airway involves draining secretions and suctioning when indicated (e.g., visible mucus, congestion).
- Trendelenburg position may be used for positioning unless signs of increased intracranial pressure (ICP) are present.
- Suctioning should be gentle, limiting duration to 10 seconds to avoid oxygen deprivation and bradycardia.
Maintaining Normothermia
- Newborns’ average body temperature at birth is 37.2°C; maintaining warmth is critical due to their immature temperature regulation.
- Factors contributing to hypothermia include low subcutaneous fat and cold delivery room environments.
- Immediate steps to keep newborns warm: drying, wrapping in a blanket, placing under radiant warmers or in an isolette (33-34°C).
APGAR Score
- APGAR is performed at one and five minutes post-birth to assess newborn’s well-being.
- Scoring (0-10):
- 0-3 indicates severe distress needing resuscitation.
- 4-6 suggests a guarded condition requiring further assessment.
- 7-10 indicates good condition, routine care needed.
Newborn Screening
- Screening tests diagnose congenital metabolic disorders using a blood sample from the heel.
- Other tests include hearing screens and pulse oximetry to assess health.
- Early detection is crucial for treatment to promote healthy development.
Head Assessment
- The head constitutes 25% of total length; features a prominent forehead.
- Both anterior and posterior fontanelles should feel soft and flat, indicating proper hydration and brain pressure.
- Premature closure of fontanelles can suggest conditions like hyperthyroidism and craniosynostosis.
Eye and Ear Observations
- Newborns often cry without tears due to immature lacrimal ducts; eyelid edema may be present for 2-3 days.
- Pupils should be round and regular; physiologic strabismus is common until four months old.
- Ears should be properly aligned; low-set ears could indicate chromosomal abnormalities.
Respiratory Assessment
- Breast engorgement may occur due to maternal hormones; "witch’s milk" (watery secretion) may also be present.
- Chest symmetry and the absence of retractions are critical indicators of respiratory distress.
Genitalia Inspection
- In females, vulvar swelling is common due to maternal hormone exposure.
- Inspect the male genitalia for normal positions and conditions like phimosis and paraphimosis.
- Signs of congenital conditions like oligodactyly (fewer than five fingers/toes) and clubfoot must also be evaluated.
