primary injury initial damage to the brain that results from the
traumatic event
not reversible
secondary injury an insult to the brain subsequent to the original
traumatic event
progressive with delayed cell death
The more time that the injury effects the more tissue that is affected/gone (Time is tissue)
the brain
The three types of mechanisms of ischemia, hypoxia, increased ICP
brain injury
The three compartments of the Brain tissue, CSF, and blood
cranium include:
The normal range of ICP is 0-15mm Hg
If one of the compartments in the they decrease
cranium increases, what happen to the
other two parts?
If all three of the compartments of the Possible brain herniation
cranium while one of the
compartments is increased, what can
happen?
,What could happen if there is a Brain herniation
sudden decrease in CSF fluid?
If the patient has increased ICP, Hell no
should you do a lumbar puncture?
delirious in an acutely disturbed state of mind resulting from
illness or intoxication and characterized by
restlessness, illusions, and incoherence of thought
and speech.
Obtunded Less than full alertness (altered level of
consciousness), typically as a result of a medical
condition or trauma.
Falls asleep unless stimulated
Stuporous Deep states of sleep: vigorous stimulation is required
but pt cannot stay awake
comatose Unable to be aroused, even with vigorous painful
stimuli; motor responses,such as withdrawal or
posturing, may occur
Decorticate posturing Contractures toward their core
Decerebrate posturing posturing in which the neck is extended with jaw
clenched; arms are pronated, extended, and close to
the sides; legs are extended straight out; more
ominous sign of brain stem damage. Most Severe.
dysconjugate gaze paralysis of gaze or lack of coordination between the
movements of the two eyes
ocular palsies One or more cranial nerves dysfunctional such that
motor paralysis of the eye impairs movements in one
or more directions
, Doll's eye reflex when you move the head, the eyes should move,
then return to a central position; in some brain
injuries, the eyes will be fixed centrally
cold calorics test tests for brain stem function with cold water. Eyes
should divert to side where cold water is being put
on
coup injury brain injury at the site of impact
contracoup injury brain injury on the opposite side of impact
GCS is taken first________ hours after a 48
TBI
The primary injury after a TBI is a hematoma:
epidural
Subdural
Subarachnoid
WHICH CAN CAUSE INCREASE OF ICP
Collection of blood between the dura epidural hematoma
and skull
LOC can be normal and then rapidly
decreases
Collection of blood between the dura Subdural hematoma
and outer layer of arachnoid
membrane: typically involves bridging
veins
Slower onset / prone to rebreeding
