Fetus to Newborn: Respiratory Changes Initiation of respirations Chemical surfactant reduces surface tension 34 -36 wks decrease in oxygen concentration Thermal sudden chilling of moist infant Mechanical compression of fetal chest during delivery normal handling

Apgar Scoring

Neurologic Adaptation: Thermoregulation The maintenance of body temperature is a major task for the NB infant (normal temperature is 97. 7 -98. 6) 1) their skin is thin and blood vessels are close to the surface 2) they have little SQ fat to serve as a barrier to heat loss 3) they have 3 x the surface to body mass as an adult 4) Preterm infants are especially susceptible to heat loss because their tone is poor and they have even less fat and thinner skin than full term babies.

Methods of Heat Loss 1) Evaporation-occurs when wet surfaces are exposed to air. 2) Conduction- occurs when the NB comes in direct contact with objects that are cooler than their skin. 3) Convection- occurs when heat is transferred to air that surrounds the NB. 4) Radiation- occurs when there is a transfer of heat to cooler objects that are not in direct contact with the infant.

Convection Radiation Evaporation Conduction

Nonshivering thermogenesis The distribution of brown adipose tissue (brown fat)

Effects of Cold Stress 1) Metabolic Rate: leads to use of glucose and production of Surfactant. This can lead to hypoglycemia and respiratory distress. 2) Non-Shivering Thermogenesis-metabolism of Brown fat. This leads to increased production of free fatty acids, which leads to metabolic acidosis and jaundice. 3) Vasoconstriction: leads to pale, mottled skin and shut down of pulmonary vessels, which leads to fetal circulation patterns.

Bonding Kennell and Klaus En face Encourage Breastfeeding Skin to skin

Periods of Reactivity First Period (30 -60 minutes) Vital signs, Color, Eyes wide open. Encourage attachment (Bonding) Apgar Scoring, radiant warmer Medications Sleep Phase (1 – 4 hours) Second Period (4 – 12 hours) Intense sensitivity to internal and external stimuli. Void and meconium Watch mucus, apnea, emesis

Nursing Assessments Vital signs Measurements Gestational Age Medications Glucose levels Temperature stabilization. What is a successful transition? ? ?

General Survey Appearance Symmetry, any obvious deformities, size, smell, muscle tone, sex, posture Behavior Crying, lethargic, responsive, reflexes, jittery

Measurements Normal Weight 2500 -4000 gms 5 ½lbs. – 8 lbs, 13 oz. (AGA-appropriate for gestational age) Below normal (SGA- small for gestational age)- <10% Above normal (LGA-large for gestational age)- >90%

Normal Length- 18 -22” or 48 -52 cm. Head circumference- 13 -14” or 32 -36 cm. (measure right above eyebrows) Chest circumference- 12 -13” or 30 -34 cm (measure at nipple line)

Vital Signs Temperature- first is usually taken axillary, but may be taken rectally to assure anal patency (36. 5 -37. 5 C or 97. 599. 5 F) Pulse- 110 -160 bpm, unless sleeping (100) or crying (180) Respirations- 30 -60 with periodic breathing B/P- only if suspected heart problem or premature infant
