Flashcards in Head Trauma, Cohen Deck (26)
1
population affected most by head trauma
men
elderly now on medications like anti platelet anti coagulation
2
general injury causing head trauma
acceleration deceleration
strike by object
cerebral edema
3
Minor head trauma
moderate
severe
minor is 9-13 on glascow scale
mod: 8-12
major: <7
4
components of glascow scale
eye movement 4
verbal response5
motor response 6
5
Volume of skull limited by
brain
CSF
blood in aa and vv
6
Cushing reflex
hypertension and bradycardia
7
most dangerous traumatic hemorrhage in brain
ruptured aneurysms
8
contusions
small ares bleeding in brain itself
usually near surface sometimes deeper
9
type of bleed from tearing of bridging veins
subdrual hematoma
10
subdurals more common in who
elderly with more room between brain and skull
11
acute vs chronic subdural hematoma
chronic is seen 21 days since onset
acute if within 72 hours
12
Sx subdural hematoma
HA
confusion
hemiparesis
seizures
CN III palsies
13
CT MRI subdural hematoma
crescent
14
Tx if patient has clear deficits and subdural is over 3 mm thick
surgical drainage
small burr holes or full craniotomy
15
do all subdural hematomas shrink
some can expand and soon deteriorate
16
what causes delayed hydrocephalus
loss of CSF earlier
17
epidural hematoma
dangerous!!
can have skull fracture
middle meningeal tear
compress brain more quickly
18
Hx epidural hematoma
suffered serious injury with loss of consciousness immediately
19
Lucid interval
lost consciousness wake up then lose again
time between is lucid interaval
20
lens shape bleed
epidural
21
Tx epidural
surgical drainage!!
22
Concussion
head trauma producing reversible decline in brain function even without loss of consciousness
23
Head CT for concussion
when loss of consciousness, persistent HA or significant neurological deficit
24
Post concussive syndrome
persistent HA
light headedness
depression
poor concentration
irritability
25
chronic traumatic encephalopathy
irreversible brain disease from multiple minor head injuries like concussions
Tau aggregation along Cx
atrophy widened sulci and large ventricles
septum pellucidum and corpus callosum damaged
