OB final - Newborn 1 Flashcards
when is meconium suctioning done
when infant is pale, limp and have no respiratory effort or tone
healthy babies just get bulb suction
which was do you milk the umbilical cord
towards the baby
components of apgar
heart rate
respiratory effort
muscle tone
reflex irritability
color
normal newborn vitals
pulse: 110-160 (can go to 80 during sleep & 180 during crying)
temp: 97.7-99.5
res: 30-60
changes in respiration: mechanical
during the birth process, the fetal chest is compressed and squeezes fluid out
c section babies are more prone to fluid in the lungs & moms who had quick labor
changes in respiration: chemical stimuli
the first breath is triggered by increased pCO2 and decreased pH and pO2 triggers brain respiratory center to breath, this is a natural result of a normal vaginal birth
changes in respiration: thermal stimuli
-decrease in environmental temp after birth
-newborn responds w/ increase in respirations
avoid prolonged exposure to cold
changes in respiration: sensory stimuli
lights
sounds
gravity
touch
periodic breathing
when the baby pauses in respiration for up to 20 seconds and that os considered normal
apneic breathing
when breathing breaks are greater than 20 seconds and is considered abnormal
transient tachypnea of the newborn
progressive respiratory distress noted by at least 6 hours of age until 72 hours in more severe cases caused by
-LGA, late preterm, maternal over sedation, maternal bleeding, prolapsed cord, breech birth, maternal DM, C sections
transient tachypnea treatment
-chest xray
-oxyhood
-IV fluids or feeding tube
what can stimulate development of surfactant in the alveoli
-giving mother betamethasone
-rupture of membranes
respiratory distress is treated by
-oxygen therapy
-surfactant administration
-thermoregulation
-ECMO
newborn circulation
-increased systemic vascular resistance
-decreased pulmonary vascular resistance
enhances perfusion of body systems
-closure of ductus arteriosus so that blood goes from the aorta to the pulmonary artery
closure of the ductus venosus which forces perfusion to the liver
when should the foramen ovale close after birth
within 2 hours
