Perfusion ICP When disrupted:
infarct - blockage of blood vessel from plaque or tumor
inter cranial hemorrhage - TBO
severe hypertension
Neurotransmission ICP When disrupted:
seizures
degenerative diseases
Pathology ICP When disrupted:
infection
alzheimer's
huntington's
When does a child's head become fixed? age 5
no room to expand when swells leading to death of tissue
Physiologic consequence of the blood brain Can become compromised and lead to infection
barrier
Physiologic process of the meninges Protective layers
Intracranial problems are usually related to a specific layer
Physiologic consequences of glucose Hypoglycemia episodes, can't function, brain death
Physiologic processes of auto regulation Blood flow
Physiologic consequences of Decrease in CO2 causes vasoconstriction
hyperventilation Decrease in blood volume and inter cranial pressure
increase risk of ischemia within first 20 hours of injury,
hyperventilate after this time
Why should we detect and prevent cerebral Leads to cerebral edema, increased intracranial pressure,
edema? decreased perfusion, decreased oxygenation, cellular death
, What is the difference cerebral edema and Edema - swelling leads to intracranial pressure
increased intracranial pressure? Intracranial pressure - finite volume of space
What are early symptoms of IICP in infants? Bulging fontanels
Increased head circumference
Lethargic
Poor feeding/weigh gain
Irritable (shrill cry)
Separation at sutures
What are early symptoms of IICP in adults? Change in LOC
C/O headache
Confusion
Shallow breathing
Nausea without vomiting or vomiting without nausea
Hypertension
What are the components of Cushing's Increase in BP
triad? Decrease in HR
Decrease in respiration
Sign of eminent death
What are important assessment findings Hypercapnia
related to cerebral perfusion pressure? Hypoxia
Hypoventilation leads to increased CO2
What are the components of the Glasgow Eye opening
Coma scale for adults? Verbal
Motor
What is PERRLA? Pupils equal round reactive to light and accommodating
CN 1 Olfactory
Olfactory Nerve Assessment Close eyes, smell, name item
CN II Optic
Optic Nerve Assessment Stand arm's length away, cover eye, nurse covered eye on
same side, stare at nurse's uncovered eye, move other hand in
field holding up fingers
Vision chart - cover one eye at a time
CN III Oculomotor
Oculomotor Nerve Assessment Assess for involuntary shaking of eye (nystagmus) - hold pen
light a foot away from the face, move in 6 cardinal fields of
gaze
Reaction to light - dim light, shine light on wow from the side,
assess constriction direct and indirect
PERRLA
CN IV Trochlear
Trochlear Nerve Assessment Stare at object far off, follow pen light as it comes closer to
the nose
