Study Notes
Newborn Thermoregulation
- Newborns are at risk of heat loss due to their small amount of heat-producing tissue (muscle and adipose tissue) compared to their exposed skin.
- Newborns cannot produce heat by muscle movement and shivering, which requires oxygen.
- Cold stress can lead to respiratory distress.
Hepatic Adaptation
- After birth, the newborn's liver breaks down excess red blood cells, releasing bilirubin.
- Bilirubin is normally conjugated and excreted in the feces, but the newborn's immature liver may be overwhelmed, leading to jaundice.
- The liver produces clotting factors, requiring vitamin K, which is normally produced by gut bacteria.
- Newborns are given vitamin K to prevent bleeding problems.
Newborn Care
- Key components of newborn care include:
- Drying and warming the neonate
- Assessment (AGPAR scoring and physical examination)
- Feeding
- Hygiene (drying and first bath)
- Promoting bonding (skin-to-skin contact, Kangaroo care)
- Vitamin K administration
- Eye care
- BCG and Hepatitis B vaccination
Breastfeeding
- Breastfeeding is the optimal source of nutrition.
- Breast milk types:
- Colostrum (rich in antibodies, produced in late pregnancy to 3 days after delivery)
- Transitional milk (lower protein, produced 3-6 days after delivery)
- Mature milk (produced 7 days after delivery until termination of breastfeeding)
Newborn Transition
- Physiologic adaptation:
- Respiratory adaptation
- Cardiovascular adaptation
- Thermoregulatory adaptation
- Metabolic adaptation
- Hepatic adaptation
- Behavioral and social adaptation
- Nursing assessment of the normal newborn includes:
- General body proportions and posture
- Vital signs
- Physical measurements
- Head-to-toe assessment
- Neurologic assessment
- Behavioral assessment
- Gestational age assessment
Metabolic Adaptation
- A steady supply of blood glucose is necessary for metabolic processes and energy production.
- Neonatal hypoglycemia (blood glucose < 40 mg/dL) can occur due to excessive stress during labor or transition.
- Risk factors for hypoglycemia: respiratory distress, cold stress.
- Early signs of hypoglycemia: jitteriness, poor feeding, listlessness, irritability, low temperature, weak or high-pitched cry, hypotonia.
- Late signs of hypoglycemia: respiratory distress, apnea, seizures, coma.
Thermoregulatory Adaptation
- Thermoregulation is the balance between heat production and heat loss.
- Newborns are susceptible to heat loss due to their small amount of heat-producing tissue.
