Objectives
• Identify primary features of fetal circulation.
• Identify physiological changes that occur at birth in
the newborn’s transition to extrauterine homeostasis.
• Identify routine care for the newborn in the transition
period.
• Identify signs and symptoms of common problems in
the transition period.
• Identify nursing intervention that promote parental
bonding.
What Is Transition???
The Transition Period
• Birth to 6 hours of age
• Physiological change from placental support to
self-maintenance
• Fetus prepares for transition over the course
of gestation
• Transition depends on gestational age and
quality of placental support
The Cardiac Puzzle
Anatomy and Physiology
• Placental Fetal Circulation
• Blood follows the path of least resistance
• Low pulmonary blood flow (only 8-10% of
right ventricular output secondary to high
pulmonary vascular resistance
The Fetal Circulation
Ductus Venosus
Foramen Ovale
Ductus Arteriosis
Fetal Lungs
Fetal Metabolism and Hematology
• Glucose
– Fetal concentrations 70-80% of maternal glucose
concentrations
• Glycogen
– Large glycogen stores provide large energy
reserves to sustain newborn through transition
period
• Brown Fat
– Unique to newborn
– Metabolized for heat
Cardiopulmonary Adaptation at Birth
Cardiovascular Adaptations At Birth
• Umbilical cord is clamped.
• Three major shunts functionally close during
transition
– Ductus Arteriosis
– Foramen Ovale
– Ductus Venosus
Pulmonary Adaptation At Birth
• Stimuli for initiating respiration
– Mild hypercapnia, hypoxia and acidosis
– Light, noise, touch
– Thoracic squeeze during vaginal delivery
• Empties approximately 1/3 of fetal lung fluid
First Breath
• Air enters lungs at 2x normal pressure
– 40-80 cm H2O
• Pulmonary vessels vasodilate in response to
increased oxygen
– Pulmonary vascular resistance decreases
– Pulmonary blood flow increases
Continued Pulmonary Adaptations
• Pulmonary vascular resistance (PVR)
decreases to reach adult levels at 2-3 weeks
of age
• Lung compliance improves
Measurements
• Apgar score
– Done at 1 minute and 5 minutes of age
– If apgar less than 7 at 5 minutes of age, continue
every 5 minutes until greater than 7 for maximum
of 20 minutes

Routine Care Considerations
AAP/ACOG/AWHONN Guidelines
•
•
•
•
•
•
Proper identification of newborn
Initial assessment within 2 hours of birth
Develop a plan of care
Document observations at least every 30 minutes until stable for 2
hours
Prophylactic eye care within 1 hour of birth
Primary health care provider
– Perform initial physical exam no later than 24 hours of birth
– Perform physical exam within 24 hours before discharge
•
•
•
Document daily weight
Perform metabolic screening
Instruct parent in care of infant
Guidelines (Cont)
•
•
•
•
•
•
Implement emergency measures, including resuscitation, when
necessary using such programs as the Neonatal Resuscitation Program
Observe parent-infant interactions
Identify with parent(s) the appropriate facility for follow-up
Inform parent(s) of importance of immunizations
Identify high-risk mothers
Evaluate home environment
Nursing Considerations
• Observations must be documented every 2
hours according to the State of Washington.
– Follow hospital policy regarding this guideline.
