Transition to extrauterine life

Lasts up to 30 minutes after birth

Alert, active RR

May appear hungry, good time to initiate breastfeeding

Bonding

Meconium

We want within 24 hrs or birth

Initiation of breathing

Most critical to establish effective respirations

Chemical factors that effect the respiratory system

Low O2, high CO2

Signs of respiratory distress

Nasal flaring, intercostal or subcostal retractions, grunting with respirations

Closure of foremen ovale

Increases pressure in the left atrium

Mom can attack baby if she has

(-) or type O blood

Platelet range of a newborn

150,000-300,000

Newborns have a thin layer of

Subcutaneous fat

Look at pic for

Convection

Radiation

Evaporation

Conduction

What keeps newborn's organs warm?

Brown adipose tissue

Hyperthermia

Excess heat production related to sepsis

Renal system of newborn

Should void within 24 hrs of birth

Pink tinged uric acid crystals normal in first week

Loss of fluid through urine, feces, lungs, increased metabolic rate, & limited fluid intake

Can result in a 5-10% loss of birthweight during the first 3-5 days of life

Less than 40 for blood glucose is considered

Abnormal

Hyperbilirubinemia

The large number of red blood cells, & their accelerated rate of destruction

Physiological jaundice

After 24 hrs of age

Resolves without treatment

If bilirubin level is greater than 12

A serum bilirubin level is done

Hyperthermia is usually a late sign of

Sepsis

Signs of infection

Temp instability

Sensory behaviors

Vision: 8-12 inches

Hearing: can hear well immediately after birth

Smell: highly developed

Taste: prefers sweet
