Module 6: The Neonate Flashcards
(105 cards)
1
Q
What 2 hormones plays an essential role in neonatal transition to extrauterine life?
A
- catecholamines
- cortisol
2
Q
What role does hormone catecholamines (epinephrine, norepinephrine, and dopamine) play in neonatal transition?
A
- 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
3
Q
What 3 roles does hormone cortisol play in neonatal transition to extrauterine life?
A
- 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
4
Q
The major adaptations associated with transition occur during the first 6-8 hours of life. What is the most critical adaptation required?
A
- establishment of effective respirations
5
Q
What are the fetal physiological (cardiopulmonary) changes that occur during transition?
A
- 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)
6
Q
What is persistent pulmonary hypertension of newborn?
A
- 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
7
Q
What are the initial steps of NRP (4)?
A
- dry
- warm
- stimulate the infant
- ensure there is an open airway
8
Q
What 4 factors stimulate the newborn to take first breath?
A
- 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.
9
Q
What are the major changes that take place in a newborns cardiopulmonary system during the transition to extrauterine life?
A
- 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.
10
Q
What is the role of lung surfactant?
A
- 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.
11
Q
What is the rapid assessment of 5 parameters that is performed after completing the initial steps of NRP? When is it performed?
A
- Apgar score
- performed and scored at one and five minutes
12
Q
What does APGAR score stand for?
A
- 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
13
Q
What does APGAR score (at one minute) of 7 or above mean? score of 4-6 mean? score of 3 or less?
A
- 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.
14
Q
What APGAR score warrants another assessment at 10 minutes?
A
- Apgar of 7 or less at 5 minutes warrants another assessment of the five parameters at 10 minutes

17
Q
What is the “sleep period” during the transition period (first hours of life) include for infant?

86
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
