All remaining lectures - except cognition not included Flashcards
some of the biggest challenges with working with pts with TBI is
permanent cognitive and behavior issues, emotional state, mood changes, communication
what does walking wounded mean
their motor function and physical states are ok, but cognitively and behaviorly they are not (TBI)
top 2 causes of TBI
transportation (ex: car, boat, plane)
falls
1 cause of TBI for pts 75 and up
falls
gunshot wound, stabbing, or skull fx would be an ex of what type of TBI
open
skull fx is an ___ TBI
open
___TBI’s result from acceleration or deceleration forces
closed
what is coup countercoup
closed TBI,
Coup injury: brain hitting front part of skul
lContracoup: brain hits front part then suboccipital region (axon shearing occurs)
not skull, but rather the brain itself….what part of the brain is effected in coup coutner coup
anterio-inferior temporal lobes and prefrontal cortex
4 classifications of TBI
- focal
- diffuse
- hypoxic
- hematoma
what is a focal TBI
a local one, can cause local swelling or hematomas
cause a mass shifting effect (swelling, blood collection, smushing ventricles and brain tissue)
what does DAI mean
diffuse axonal injury
FOCAL hematomas cause
a mass shifting effect (swelling, blood collection, smushing ventricles and brain tissue)
explain diffuse TBI
Shearing and retraction of axons
Can cause coma = poorer outcome
why is a diffuse TBI often a problem to dx
DAI may or may not show up on imaging! (there is just edema, no collection of blood)
this type of TBI is often caused by drowning, it is
Due to systemic hypotension, anoxia, vascular damage
Can lead to global damage
hypoxic, aka ischemic
3 main types of hematomas (TBI classification)
epidural
subdural
intracranial
this type of hematoma is located btwn your skull and dura mater
epidural
this type of hematoma is often arterial – quick developing
epidural
with a(an) _______hematoma there is usually a period of normal function, and then quickly there is N/V and UMN sx
epidural
hematomas are classified according to
where the bld collects
elders that are on blood thinners that fall and hit their head are prone to ___ hematomas
subdural
subdural hematomas effect what type of BV
venous
Venous
Develop slowly, over time
UMN signs and confusion
which type of hematoma
subdural
