Study Notes
Neonate/Newborn (15-17)
-
Neonates (0-28 days) are completely dependent on the placenta for circulation and oxygenation before birth. Extrauterine life begins when the umbilical cord stops pulsating and the neonate starts breathing.
-
Priorities in the neonatal period include: drying, warming, positioning, stimulation (suction as needed), APGAR scores, maintaining body temperature, respiratory function, infection prevention, and support for parents. APGAR scores (1 & 5 minutes) are crucial; 7-10 is good, 4-6 needs support, and 0-3 needs resuscitation.
Defining Neonate
-
Preterm: Infants born before 40 weeks gestation are at increased risk of complications including placental dysfunction (fetal hypoxia, late decelerations), meconium aspiration, hypoglycemia, hypothermia, birth trauma, and postpartum hemorrhage (PPH).
-
Appropriate Gestational Age (AGA): A healthy infant at expected birth weight and size as defined by gestational age.
-
Large for Gestational Age (LGA): Infants weighing 4000-4500 grams, often associated with postmaturity, maternal diabetes, or multiple pregnancies. Large size increases postpartum complications.
-
Small for Gestational Age (SGA): Infants whose weight is significantly lower than expected for their gestational age. This can result from Intrauterine Growth Restriction (IUGR), caused by factors reducing blood flow to the placenta. These include smoking, vascular diseases, cardiac issues, and chronic hypertension.
Immediate Changes After Birth
- Chest compression during vaginal delivery stimulates respirations.
- Umbilical cord cessation of pulsation triggers hypercarbia, hypoxia/acidosis, which in turn stimulate respirations.
- Respiratory changes result in altered pulmonary blood vessel pressure and lung blood volume.
- Neonates transition from fetal to normal (adult-type) circulation.
Cold Stress/Thermoregulation
-
Neonates regulate temperature through extremity movement, vascular constriction (cool, pale skin), and brown fat metabolism.
-
Premature infants are at higher risk for cold stress (hypothermia) due to decreased brown adipose tissue (BAT), inability to shiver, and a larger body surface area.
-
Prevention of cold stress involves drying the infant, covering the head, skin-to-skin contact with mother, and using warm blankets.
-
Treatment of cold stress entails ensuring the baby is dry, head is covered, swaddled or in a warm environment, monitoring temperature, checking glucose levels, and treating hypoglycemia.
