hypoxic ischemic encephalopathy Flashcards
how do you get hypoxic ischemic encephalopathy
pulmonary/placental compramise = cardiorespiratory depression = hypoxia, hypercarbia and metabolic acidosis, low cardiac output = reduced tissue perfusion
hypoxic ischemic encephalopathy long term sequaely
brain damage
why might gas not be exchanged across the placenta
prolonged uterine contractions, placental abruption, ruptured uterus
why might gas not exchange by the cord
cord compression/cord prolapse
what may prevent plaental perfusion
hypertension/hypotension
mild affects of HIE
irritable, responds excessively to stimulation, staring of the eyes and hyperventilation and has impaired feeding
moderate affects of HIE
abnormalities of tone and movement, cannot feed and seizures
severe affects of HIE
abnormal movements or response to pain; hypotonia and hypertonia; seizures are prolonged and often refractory to treatment; multi-organ failure
why restrict fluid in HIE
renal impariment
what can reduce the brain damage in HIE
cooling within first 6 hours
common sequely of severe HIE
cerebral palsy
in immature infants what is breast milk supplemented with
phosphate
why are preterms more prone to infection
IgG is mostly transferred across the placenta in the last trimester
effect of vervical infection on pregnancy
common cause of preterm labour
