newborn transition

lungs site of gas exchange
heart circulation pressure increase in left atrium causing foreman ovale to close
hepatic portal ductus venosus closes, hepatic portal circulation begins
thermoregulation body temperature is maintained through flexed posture and brown fat
120-180 beats per minute heart rate first few minutes of birth; decreases to average 120 bpm
cord blood natures first stem cell trasnfplant because it possess regenerative properties
surfactant surface tension reducing lipoprotein -prevents alveolar collapse
periodic breathing cessation of breathing that lasts 5-10 seconds without changes in color or heart rate
thin skin with blood vessels close to the surface, lack of shivering ability limited stores of glucose, lack of subcutaneous fat heat loss
newborn temperature may decrease 3-5 degrees within minutes 99.6
conduction trasnsfer of heat from one object to another when the 2 objects are in direct contact with each other-heat fluctuations from the newborn surgace to other surfaces such as cold mattress, scale
convection flow of heat from the body surface to cooler surrounding air or to air circulating over a body surface. cool breeze from an open door
evaporation loss of heat when a liquid is converted to a vapor.amniotic fluid evaporating into the air causing this type of heat loss - apply hats and blankets
radiation loss of body heat to cooler, solid surfaces that are in proximity but not in direct contact - placing the newbown in a isolette next to a cold window
overheating isolette that is too warm or one that is left too close to a sunny window can cause this
non shivering thermogenesis primary method of heat production-which brown fat (adipose tissue) is oxidized is response to cold exposure
jaundice icterus-yellowing of skin , sclera, and mucous membranes due to increase bilirubin
meconium newborns first stool; amniotic cluid, shed mucosal cells and intestinal secretions and blood
feeding small frequent feedings
breast fed stool yellow gold loose and stringy -
formula fed yellow, yellow green or greenish and loose pasty or formed with an unpleasant odor
acquired immunity 2 primary processes - development of circulating antibodies and formation of activated lymphocytes used to destroy foreign invaders
IgA found in breast milk, causing a significant immunologic advantage
hearing reponds to noice by turning to sound
taste ability to distinguish between sweet and sour by 72 hours old
smell knows difference between moms breast milk and others
touch sensitive to pain, tactile stimuli
vision incomplete at birth; close objects 8-10 inches
reflex involuntary muscular reponse to a sensory stimulus
first period of rectivity birth and may last from 30 min to 2 hours-alert, moving and may appear hungry- good to intiate breast feeding now
decreased reponsiveness 30-120 minutes of age -good for mom and newborn to stay close and rest
second period of reactivity 2-8 hours - newborn passes meconium-teaching about feeding and diaper changing techinique is reinforced now
neurobehavioral response how they react to the environement - orientation, habituation, motor maturity, social behaviors and self-quieting ability
orientation response to stimuli
habituation process and respons to visual and auditory stimuli
motor maturity control and coordinate movement
self-quieting ability ability to quiet and comfort themselves
social behaviors cuddling/snuggling into the arms of the parent when held-
neonatal period first 28 days of life
