Neuro Flashcards
structural differences
larger heads, mobile spines, fontanelles fuse after brain growth slows, skull thickness increases with age, skull pliability decreases with age, vascular brain. develops rapidly in toddler years
types of reflexes
step- 4-8whs, rooting- 3mo, suck- 2-5mo, moro and tonic neck- 4mo, palmar grasp- 4-6mo, plantar grasp- 9mo, babinski- 12mo
neuro assessment
hx, observation of LOC, social interactions, cranial nerve function, motor function, tracking objects, VS, reflexes, sensory.
nursing interventions for all
airway, oxygenation, hydration, nutrition, safety, skin integrity, neuro function, prevent infection, pain mx
craniosynostosis
premature closure of cranial sutures, abnormal shape of skull. r/f genetics, AMA, male, teratogen exposure during pregnancy. either simple 1 suture or complex multiple sutures. sx increased ICP and head malformation. tx with surgery before 6mo and helmet after
positional plagiocephaly
asymmetry and flattening of head from external forces. increased with back to sleep campaign. r/f are preterm, multiple gestation, low activity, torticollis. <right occiput can affect depth perception. tx with frequent positioning and helmet
spina bifida
neural tube defect. occulta- malformation of vertebrae and absence of bone, see tuft of hair or dimple. mengigocele- pouch cyst containing meninges, may have neuro or musculoskeletal deficits. myelomeningocele- pouch sac containing meninges and spinal cord nerves, more severe deficits like hydrocephalus and paralysis.
myelomeningocele mx
protect pouch with non adherent dressing and sterile, baby in prone position, hips flexed and abducted, open diaper, manage I&O/temp/nutrition/infection control, latex free sign, encourage parent bonding, pain mx. may require shunting for hydrocephalus, risk of uti, orthotics, promote growth and development
encephalocele
neural tube defect, skull doesnt completely fuse at base of neck or face. brain is malformed with complete development, brain protrudes thru opening. often see hydrocephalus, neuro deficits, delays, vision problems, seizures.
encephalocele tx
surgery to replace brain back into skull, wont correct neuro deficits. protect protrusion, neuro assessments, ICP monitoring, reflexes, seizure activity.
anencephaly
neural tube defect where brain and skull dont form correctly, functional brainstem only no brain matter, most are fatal and need comfort measures.
microcephaly
abnormally small head, primary is genetic and chromosomal, secondary is exposure during fetal development to radiation/infection/etoh. wide range of cognitive impairment, head circ >3 standard deviations below mean. no cure just supportive care
hydrocephalus
buildup of csf in brain usually in ventricles. from increased csf production, decreased absorption, or flow obstruction.
hydrocephalus sx
increased intracranial pressure, dilated scalp veins, bulging anterior fontanel, large head, sun setting eyes, apnea, irritability, ha, vomiting.
hydrocephalus tx
ventriculoperitoneal shunt, prevent infection, monitor for patency by sx improving, may need replacement through lifetime.
headaches
acute or chronic and mild to severe. rule out serious conditions like tumors, infections, increased ICP.
ha sx
irritability, lethargy, head holding or banging, sensitivity to sound or light. red flags are progress in severity or frequency, awakes from sleep, worse upon arising, N/V, changes in gait, made worse by valsalva maneuver
ha tx
relaxation, otc rx, migraines take triptans/antiemetics/analgesics, ha journal to find triggers (foods, related to hormones, weather, change in routine, stress, activity, sensory triggers)
head injury
trauma resulting in injury to scalp, skull, brain, or blood vessels. primary from force and secondary from injury. accidental or nonaccidental. causes are falls, sports, mvc, abuse, infants at risk cause large head.
head injury sx
ha, confussion, dizzy, vision change, lethargy, decreased loc, pupil change, sun setting eyes, retinal hemorrhage, raccoon eyes, gait change, seizure
head injury tx
stabilize c spine, maintain airway, gsc score, avpu, observe posturing, monitor icp and map, monitor for hemorrhage.
pediatric stroke
perinatal stroke is last few months of pregnancy to 1mo, childhood stroke is 1mo-18yr. similar mx to adult, nutrition and hydration.
perinatal stroke
cause unknown. r/f congenital heart disease, placenta disorder, blood clot disorder, infections. sx are repetitive motions, twitching, apnea with staring, decreased mvmt, weakness on one side, hand preference before 1yr.
childhood stroke
r/f are congenital heart disease, disease affecting brains arteries, infections, head trauma, sickle cell, autoimmune. sx are FAST, sudden ha, vomiting sleepy, weakness, numbness on one side, difficulty speaking, vision loss, dizzy. dont delay with tx
