Module 6: The Neonate Flashcards
What 2 hormones plays an essential role in neonatal transition to extrauterine life?
- catecholamines
- cortisol
What role does hormone catecholamines (epinephrine, norepinephrine, and dopamine) play in neonatal transition?
- promote fluid clearance from lungs
Surge in response to the normal birth process:
- responsible for increased blood pressure after birth, - adaptation of energy metabolism,
- initiation of thermogenesis from brown fat
What 3 roles does hormone cortisol play in neonatal transition to extrauterine life?
- key regulatory hormone
- Clearance of lung fluid
- Lung maturation (anatomy and surfactant)
- Gut maturation
- cortisol level starts to increase around 30 weeks gestation
- Maturation of glucose metabolic pathways in the liver
- Maturation of the thyroid axis
The major adaptations associated with transition occur during the first 6-8 hours of life. What is the most critical adaptation required?
- establishment of effective respirations
What are the fetal physiological (cardiopulmonary) changes that occur during transition?
- initiation of gas exchange across alveolar membrane
- expansion of lungs with air
- rise in arterial pO2
- rapid decrease in pulmonary vascular resistance and increase in pulmonary blood flow
- pressure gradient changes (decreased right side pressure/increased left side pressure in heart)
- closure of circulatory shunts (foraman ovale, ductus arteriosus)
What is persistent pulmonary hypertension of newborn?
- During the stabilization period, which occurs over several hours, the pulmonary vessels remain very responsive to the effects of hypoxia.
- Hypo-expansion of the lungs, hypoxemia, –> persistent acidosis –> result in high pulmonary vascular resistance, delayed clearance of lung fluid, –> persistent right to left shunting
What are the initial steps of NRP (4)?
- dry
- warm
- stimulate the infant
- ensure there is an open airway
What 4 factors stimulate the newborn to take first breath?
- Chemical: factors in a newborn’s blood (low oxygen, high carbon dioxide, and low pH) which stimulate respiratory center in brain.
- Mechanical: release of pressure on a baby’s chest, as the chest is born, may stimulate breathing and chest expansion.
- Sensory: stimulation from drying, lights, sounds, smells all involved in stimulation of respiratory center
- Thermal: change from temperature from warm intrauterine environment to cool extrauterine environment stimulate skin receptors which stimulate respiratory center.
What are the major changes that take place in a newborns cardiopulmonary system during the transition to extrauterine life?
- the lungs become the primary organ of gas exchange (instead of the placenta); the lungs inflate, fluid is cleared from the alveoli, pulmonary vascular resistance decreases rapidly and there is increased pulmonary blood flow.
- The pressure gradient in the newborn’s heart shifts. Right sided pressure which was high in fetal circulation decreases, and left sided pressures which were low now increases. As a result the foramen ovale closes.
- Rising pO2 causes smooth muscle cells in the ductus arteriosus to constrict thereby closing the shunt.
- Removal of the low pressure placental system increases the pressure in a newborn’s circulation which increases circulation and pulmonary perfusion.
What is the role of lung surfactant?
- Surfactant lowers the surface tension of the alveoli thereby reducing the pressure required to keep the alveoli open.
- Decreased surface tension also results in increased lung compliance.
What is the rapid assessment of 5 parameters that is performed after completing the initial steps of NRP? When is it performed?
- Apgar score
- performed and scored at one and five minutes
What does APGAR score stand for?
- A: appearance (colour): generalized skin colour
- P: pulse (heart rate): based on observed movement of chest wall
- G: grimace (reflexes) “response to stimulation”: based on degree flexion and movement of extremities
- A: activity (muscle tone): based on presence of grimace, crying or active withdrawal
- R: respirations (breathing):
based on auscultation or palpation of umbilical cord
What does APGAR score (at one minute) of 7 or above mean? score of 4-6 mean? score of 3 or less?
- A score of 7 or above at one minute indicates that an infant is making a good adjustment to extrauterine life.
- A score of 4 to 6 at one minute indicates that an infant is having some difficulty
- A score of 3 or less at one minute indicates severe distress.
What APGAR score warrants another assessment at 10 minutes?
- Apgar of 7 or less at 5 minutes warrants another assessment of the five parameters at 10 minutes
What are the predictable phases of activity and rest during the transition period for full term healthy infant?
“What are the 3 stages of newborn transitions periods?”
- first period of reactivity: within minutes after birth and lasting for 30-60 minutes

What is the “first period of reactivity” during the transition period (first hours of life) include for infant?
- Within minutes after birth and lasting for 30-60 minutes.
- In this period, infants are in a quiet alert state: eyes wide open and capable of responding to their environment.
- Healthy infants are in an optimal state for the important first meeting with their parents. Heart rate increases to 160-180 bpm, then settles to 100-120 bpm by 30 minutes of age.

In order to maintain normal blood sugar, what should infant be doing?
- in order to maintain a normal blood sugar, infant feeding should be established in the first few hours of life
- at birth when the umbilical cord is cut, the newborn no longer receives the maternal source of glucose.
- the first feed occurs during the infant’s first period of reactivity
Is it normal for healthy newborn to have blood sugar as low as 2.0mmol/L (or even 1.8mmol/L)?
- Canadian Pediatric Society (CPS) position statement on hypoglycemia states hypoglycemia cannot be defined by a single value of glucose
- blood glucose levels as low as 2.0 mmol/L (or even 1.8 mmol/L at 1 h of age) are not uncommon in healthy newborns

Why is attachment crucial for in infants?
- crucial for the infant’s physical, psychological, and emotional health and survival
What is bonding vs attachmment?
Bonding:
- refers to earlier processes through which the parents becomes acquainted with infant, identifies the infant as an individual, and claims the infant as a member of the family
- Over time, positive interactions between the parent and the infant through social, verbal, and nonverbal responses (whether real or perceived) facilitates the development of secure parent-infant attachment
Attachment:
- is developed and maintained by proximity and consistent responses to infant cues

What defines post term infants vs post mature infant?
- infants born after 42 weeks gestation may be referred to as post term or post mature
- infant who is born after 42 weeks gestation but does not show any signs of reduced placental functioning; meaning they continue to grow in utero, is considered a post term infant
- a post mature infant has experienced placental insufficiency which results in a loss of subcutaneous fat, dry cracked skin, and increased risk of meconium being present in the amniotic fluid
- post mature infant has experienced placental insufficiency resulting in increased risk of perinatal mortality/morbidity related to intrauterine hypoxia
Is the passage of meconium into the amniotic fluid normal function?
