Immediate extrauterine newborn transition - answer--—immediate
transition from intrauterine to extrauterine life
Immediate extrauterine newborn transition depends on changes in four
major areas: - answer--—respiration,
—circulation,
—thermoregulation, and
—glucose regulation
Biochemical Factors in initiation of respiration - answer--—relative
hypoxia at the end of labor
Physical stimuli Factors in initiation of respiration - answer--—cold,
gravity, pain, light, noise
Physiologic Factor in initiation of respiration - answer--Recoil from
pressure on thorax while passing through vagina
,Sustained respiration depends on coordinated response of the
following - answer--a. Central nervous system (CNS) respiratory center
b. Aortic and carotid chemoreceptors
c. Thoracic mechanoreceptors
d. Diaphragm and respiratory muscles
Initial breathing serves the following purposes - answer--a. Assist in
conversion from fetal to extrauterine circulation
b. Clear lungs of fluid
c. Establish lung volume and expand alveoli
Characteristics of normal newborn respiration - answer--a. Respiratory
rate 30 to 60 breaths per minute
b. Irregular/fluctuating pattern
c. Diaphragmatic and abdominal breathing
d. Obligate nose breathing
e. Absence of nasal flaring, grunting, and retractions
Circulatory changes - answer--Transition from fetal to adult circulation
begins with clamping of the umbilical cord and continues throughout
the first weeks of life
,Characteristics of fetal circulation - answer--a. Low-pressure system,
including placenta (low-resistance circuit)
b. Minimal circulation to lungs; bypassed via foramen ovale and ductus
arteriosus
c. Foramen ovale favors circulation of most oxygen-rich blood to the
brain
Transition from fetal to neonatal circulation - answer--a. Increased
systemic resistance due to loss of placental circuit
b. Increased pressure in left atrium causes functional closure of
foramen ovale
c. Initial respiration opens pulmonary vasculature, favoring circulation
to lungs
d. Increased oxygenation of circulating blood causes constriction and
functional closure of ductus arteriosus
e. Absence of placental circulation closes ductus venosus
Thermoregulation *Mechanisms of neonatal heat loss* - answer--a.
Convection
b. Conduction
c. Radiation
d. Evaporation
, Thermoregulation *Neonate creates heat in three ways:* - answer--a.
Shivering (inefficient)
b. Muscle activity (limited benefit)
c. Thermogenesis by metabolism of brown adipose tissue (BAT)
High risks infants with ineffective Thermogenesis - answer--(1) BAT
stores are decreased in *preterm and growth-restricted fetuses*
(2) *Hypoglycemia* decreases efficiency of BAT metabolism
Thermoregulation *Consequences of cold stress* - answer--a. Increased
oxygen consumption, leading to relative hypoxia and acidosis
b. Metabolism of BAT and release of fatty acids decreases pH
c. Increased use of glucose, depletion of glycogen stores, and
hypoglycemia
d. Worsening hypoglycemia and acidosis may result in respiratory
distress
Thermoregulation *Management/Interventions to promote* - answer--
a. Skin-to-skin contact on mother's chest or abdomen with blanket over
both
b. Prewarm blankets and resuscitation area
c. Dry the newborn immediately and replace wet blankets
d. Regulate room temperature and minimize exposure to air convection
