game day 4 Flashcards
(30 cards)
4 types of skull fx
linear, basilar, comminuted, depressed
head injury, BP is 70/30, tachycardia - what is happening
hypovolemic shock
what is state of pupils when there is diffuse cerebral edema
bilat dilation with sluggish response
cushings triad, what it indicates
- inc BP/dec HR/altered breathing &
- indicates inc ICP
two most injurious phases of whiplash
2 and 4
4 cerebrum lobes/functions
- occip/vision,
- temporal/hearing,
- parietal/sensory,
- frontal/planning & judgem
bad idea to stop BF or CSF from head trama
will back up and inc ICP
type of skull fx results from pariorbital ecchymosis or battle’s sign
basilar frx
results from avulsion of a triangular shaped fx from anteroinferior portion of CVB
teardrop fx
bruising/swelling of cerebrum in coup-countracoup pattern
cerebral contusion
best indicator of a pt status post head injury
level of consciousness
traumatic spondylolisthesis of pars/pedicles of C2, often after hyperext wound
hangman’s fx
pt suffers R focal lesion, contusion/hematoma after head trauma, describe pupil state
L normal, R dilated/fixed resp
most imp spinal injury indicator
mechanism
3 meningial layers
dura, arachnoid, pia
recent spinal trauma, pt reports numbness in groin, trouble making it to bathroom
911/cauda equina
how severe whiplash occurs at low speeds
up to pt of vehicle deform, all forces are transferred into pt
dmg to cord produces periph vasodilation, periph resist to BF dec, bp falls - cond?
neurogenic shock
less injuries if you are aware/unaware in MVA
unaware, no bracing
type of fx prod by direct vertical/axial loading of atlas
burst/jefferson frx
temp distrub in brain fx due to brain rattled in skull from blow
concussion
grading system to meas severity of brain traum and 3 main resp
glasgow scale/ verbal consc, motor consc, eye opening
type of dens frx descends into body of c2
type 3 [type 1 at tip, type 2 at base, less likely to heal]
cond assoc with skull frx in temp area, blood collects bt skull and meninges
epidural hematoma
