WEEK 9 Flashcards
neuro: traumatic brain injury, brain tumor
indications of head injury : what is it ?
scalp wound
fracture
swelling, bruising
loss of conciousness
nasal discharge
stiff neck
head injury : emergency management interventions
initial scene
what would you do ?
calm gentle approach, get info from patient or others with the pt - what happened ? ( did the person lose conciousness )
head injury : emerg management interventions
what is the number one thing that is very important in this case ( aside from conciousness )
patent airway, stabilize cervical spine until x-ray
head injury : emergency management interventions : initial at scene : what would you do if a pt walks in with an external bleeding ?
apply pressure to external bleeding, warm blankets
Head injury : emerg management interventions : initial at scene what would you assess for ?
rhinorrhea/ ottorrhea / scalp wounds
head injury : emergency management interventions
once have access to hospital
02 via NP or re breath mask
establish 2 large bore IVs ( large gauge cannula )
true or false. do we give iv fluid cautiously, give drugs to decrease icp and increase cpp , control pain, seizures when the pt has an access to hospital. ( we are talking about a head injury : emerge management interventions )
yes this is true
is it important for the patient to be warm once have access to hospital ?
yes it is important especially for a patient who had a head injury : emerg management interventions this is something that we would do
what are the type of monitoring we are doing for our head injury pts as an emerg management interventions ?
frequent VS neuro checks ( monitor for change in LOC )
true or false ongoing monitoring of VS, 02 SATS, cardiac rhythym , GCS pupils and limb strength is something we need to utilize once the patient has an access to the hospital when they had a head injury ?
yes this is true
what do we need to ask the patient ( if they have a head injury : emerg management interventions and have an access to the hospital ) ?
ask for pt health hx, allergies, meds: provide support for patient and family
what type of health history are we going to ask the patient ?
diabetes
hypertension ( think abt allergies and medications )
what could we do physically to access the pt?
cns fluid flowing out their ears ( look for blood and clean their hair ) looking for wounds
usually anticobital - this gives fluid
what duration of ays is typically intense for a traumatic brain injury ?
first 5 days is intense ( and monitoring should be happening during these 5 days )
what is the severity range for traumatic brain injury :
severity range : mild ( concussion) , moderate, or severe ( traumatic brain injury TBI )
who are working on traumatic brain injury ? and what can it lead to ?
typically neurosurgery is an intervention/ working with physician/team
this could lead to impairment in cognition, mobility, sensory perception, psychosocial function- temporary or permanent
traumatic brain injury ; presentation depends on what ?
severity of the injury - speed and force
location :
- frontal, occipital, parietal , basilar
- focal or diffuse , open or closed
surgery - may depend on locstion of injury
what is the diagnoses for traumatic brain injury
CT head - repeat CT scan and compare
true or false. Make sure infection doesn’t become significant.
true
what is consider different level of injury ?
fell in the head or hitting a bat ( different level of injury )
what is basilar?
is at the base of the skull
what does focal or diffuse mean or open or closed ?
focal or diffuse means in a certain spot ( diffuse mean all through the brain )
open means skull fracture and been broken
close means the skull hasn’t been fracture and all intact
what does a mil concussion look like ?
may not feel great but the next day feel good, and then doing sports/work
what does frontal lobe affect ?
intellect
what does temporal lobe?
hearing, smell , taste
memory ( short term )
reading
occipital lobe what does it do ?
visual reception
writing
eyes to opposite side body awareness
whar does parietal lobe control ?
sensory discrimination
what alters the presentation of clinical manifestations ?
the location of skull fracture
what are examples of basal skull fracture
battles sign ( post auricular ecchymois )
what are the raccoon eyes ( bilateral periorbital ecchymois ) what does this under go to
have bilateral black eyes or shadow underneath
this undergoes basal skull fracture
what are some complications of facial and skull fractures
dural tear is common ( csf leak )
recall that a complication of facial and skull fractures
is dural tear and this is common known as a csf leak which can cause meningitis
explain how
infection can get into csf fluid ( circulating in your spine and brain )
if you were to hit or injured hard enough to fracture the skull very likely for dura mater will be torn - this is a huge risk for meningitis
abx is a big deal
True or false.the safety of ng tube insertion is important.
bonus : why would this be important ?
this is important as head injury may have facial fractures safety ! ng insertion`
how do we make sure ng insertion is not causing head injury ( fracture )
make sure the ct
fracture and eye orbital shown in the pic ( slide 7 )
if u have that fracture very likely they have fractured their nose
with nasal drainage it is important to know if it is what ? what sign are you looking for ?
mucus or csf leak
looking for a halo sign
if we see a nasal drainage - is it mucous ? what is a quick way to find out ?
is to get a drop of the mucous 2 by 2
but 2 by 2 to catch those drops
not putting just to know for sure there are no facial fractures
the halo effecting of leaking : typically what does this look like ?
serosanguinous in the centre
cerebrospinal fluid around
what does the halo effect of leaking indicae?
this is a major head injury
look at his ears ( a bunch of blood and in the sheet )
focal head injury
depends on how ?
on how the person was hit
focal finding - the person was hit in the front ( which will mainly affects in the brain or overall increased in ICP )
focal head injury: contusion
bruising of brain tissue within the focal area
focal findings but can lead to overall IICP
what are common in focal head injury contusion
seizures are common
what does the prognosis depends on in focal head injury
prognosis depends on severity of contusion and whether it continues to evolve
focal head injury : contusion what coup contre coup injury lead to ?
multiple contusions ( direct impact site and opposite side )
direct impact ( getting hit by a bat in the middle of the head )
diffuse axonal injury ( DAI )
What does this mean ?
widespread axonal damage
90% with severe DAI remain in a vegetative state
how long can diffuse axonal injury take after initial TBI to occur?
12-24 hours
diffuse axonal injury ( DAI )
what does this result in ?
results in global cerebral edema and IICP
diffuse axonal injury is shaken ?
shaken like a bowl of jello
—searing of neurons - overall
—-diffuse nerve axon injury
what is the complication of head injury
hemorrhage
complications of head injury : hemorrhage
emergency ( if its an artery ) blood filling in the space and the pressure in that head
arterial bleeds and these people need emergency surgery quickly
what are the two complications of head injury : hemorrhage
epidural hematoma and subdural hematoma
what is epidural hematoma ( know that this is emergent ) what is the location?
between dura and skull
what is this describing : usually arterial - bleeds fast, pressure in skull ( ICP ) increases fast
epidural hematoma ( emergent )
nsg care for IICP : is needed for ?
epidural hematoma
what requires an immediate surgery to remove bleed?
epidural hematoma which is emergent
what is the location for subdural hematoma
between dura and arachnoid space
usually venous
what is needed for subdural hematoma?
surgery is needed to remove the bleed
nsg care for iicp
subdural hematoma what is it typically ?
usually venous
- acute
- subacute
- chronic
define what she said in the video : for subdural hematoma
also serious but this is venous the blood collecting is going slower and not as urgent
what would they do for subdural hematoma
they’ll do a ct scan surgery to remove collection of blood
true or false. our job as a nurse is treating the increased intracranial pressure for subdural hematoma ?
yes this is true
head injury : nursing management
what is our overall goals
maintain adequate cerebral perfusion
remain normothermic, might cool the pt
be free from pain discomfort and infection
true or false. attain maximal cognitive motor and sensory function is important when it comes to managing a head injury
true
as nurses what is important to look at for a head injury ?
lets give them time, lets look at the LOC and neuro status
what is the key nursing assessments for head injury and nursing management
nursing assessment record
- monitor changes in LOC and neurological status
CSF leak is identified as a key nursing assesments ?
yes this is seen as a csf leak
-doing a halo test is beneficial
what is important to treat for a head injury ?
treat iicp
what does the brain need?
oxygenated blood and not have damage, we want to make sure normothermic- meaning normal body temperature
if they have icp - icu we cool the patient (cooling blanket ) - rectal thermometer and try to lower down the temp0
treat IICP
vessels in the brain starts shutting down
treatment is quite similar
what is the classification for brain tumors
benign
malignant
metastatic
what does benign
malignant
metastatic identify as in the brain tumor ?
benign is not cancerous
malignant is cancer
metastatic - this is cancer somewhere else in the body and now travelled to their brain
if brain tumor is not cancerous why is this stills serious?
if you have something taking place , you are going to get cerebral edema and high icp
true or false. Eventually all brain tumours unless they have some treatment can lead to death ?
yes this si true
depending on where the brain tumour is - sometimes we cannot remove it
why do they not do brain surgery sometimes ?
the risk is too high – remove tumour for example L will be blind not able to move legs or stop breathing
what is a classic sign or symptom of brain tumour ?
dull headache is a classic sign and symptom ( but this depends on the location )
the person has hormones that arent normal and this could also be a sign, however what is one thing that would never go away when u have a brain tumour
dull headache , this is constant and always there
recall that headache is constantly there when someone has a brain tumour- when does it usually get worst
it gets worst at night ( the person is lying down - more swelling there )
the headache is so bad it wakes the person up
recall that headache is a number one constant thing with brain tumor what else?
seizure
nausea and vomiting from increase of intra cranial pressure
cognitive dysfunction ( not thinking clearly )
memory problems
all depends on where it is
brain tumours - collaborative care
what decreases the inflammation?
corticosteroids
- dexamethasone ( this works ery quickly and decreases
inflammation – brain tumour often times is started off with this ) it reduces cerebral edema and can help decrease symptoms
what is important to manage in brain tumours as we doing a collaborative care
recall we use corticosteroids ( dexamethasone to decrease inflammation )
build up of csf fluid in the brain, they can pout a shunt in ( commonly done in children when they have this as a problem )
goes from ventricle of brain all the way down to the side of neck and then peritoneal cavity
true or false. csf should be sterile
true this should be sterile
brain tumors - collaborative care
surgery to remove or debulk mass
go more in depth abt these interventions
craniotomy
stereotactic radio surgery ( high dose radiation precisely delivered )
brain tumours - collaborative care
recall it is important for surgery to remove or debulk mass ( craniotomy and stereotactic radiosurgery ( high dose radiation precisely delievered )
what else is important ?
radiation ( internal, external )
chemotheraphy
nsg care for IICP
pts level of conciousness should be assessed ( this is important )
caused this can indicate decline if it has changed
this is true
surgery options : craniotomy
recall this is one of our surgery options what is this doing
remove bone flap ( safety )
remove clot or tumour or fix problem
establish a drain
—- re- attach bone flap ( later time, not urgent )
if the brain is swollen what is initially happening to the brain ?
squeezing i no matter what were doing if it is swelling/give them room
go to the or and cut the bone out and remove it
what used to be a practice before but now is not practice for craniotomy
they use to put them in jars and save them but the practice now is make a small incision in the bone and close it up – why do they do this ?
by having no bone that means that brain is having a little bit more space to given ( swell up more and doesnt get squish )
yes this is true
establish drain what are we initially utilizing ?
jackson pratt ( after these pts - these surgery is their bone flap it is important as nurses, we are not turning them on that side ) brain is pushing on that skin
post op care for craniotomy
where are the patients located ?
ICU or stepdown for close monitoring
what do u have to make sure during post op care craniotomy
make sure their ICP is in the normal stage, their cpp is also important ( how much blood flow and perfusion pressure naturally dips down- very swollen brain
what can poor perfusion lead to ?
it can lead to more brain problems ( not just injury and the fall ( taking care of that patient ) gets icp as normal as possible
what is important for post op care craniotomy
monitor/treat for IICP, while maintaining CPP
post op care craniotomy : what is there to see ?
periorbital edema and ecchymois
post op care craniotomy :
prevent, assess, tx any complications such as
pneumonia, stress gastric ulcer, DVT/PE , constipation , fluid and electrolyte balance
infection prevention / care of drsg to head is important when it comes to post op care craniotomy , what should be practiced ?
sutures/staples in for 7-10 days
pain, nausea control, anti-seizure med is important ?
yes it is important
what is potential determined once cerebral edema and iicp subside ?
rehab is potential determined, referrals to speciliasts , long process, personality
be careful with incision , what is a possibility that could happen with an irritated brain ?
seizure or epilepsy
what is another surgical options?
burr hole
describe burr hole
often used for subdrual hematoma
what is often used for subdural hematoma
burr hole
how many holes are drilled thru the skull ?
1 or 2 holes
hematoma is evacuated
can leave drain in for a few days
what is stereotactic methods
stereotactic radiosurgery
radiation used to destroy brain tumour
how is the patients head positioned in stereostatic radio surgery
patients head is held still by a stereotactic frame
gamma knife ( high dose of radiation is delivered )
stereotactic bx/surgery ( is not heavily sedated )
used for brain biopsies, small tumours, abscesses etc
apparatus and computer used to find precise area of brain
surgeon enters with fine instruments
what is this describing ::?
stereotactic bx/surgery
S&S of IICP brain tries to compensate
is important to pay attention to this
what is the early signs : ( your compensatory mechanisms are still intact )
altered LOC ( confusion, restlessness )
- unilateral pupil change in size, equality, and/or reactivity )
altered resp pattern ( bradypnea or irregular pattern )
true or false. what is the variable signs : for early signs
focal findings ( eg speech, difficulty , visual disturbances )
- papilledema
-vomiting
-headache
-seizures
what are the late signs of S&S of IICP brain tries to compensate
compensatory mechanisms failing
decrease in LOC ( stupor )
- unilateral or bilateral pupillary changes : size, equality, and/or reactivity
late signs is seen as your compensatory mechanisms are failing , how is the breathing pattern ?
ineffective breathing pattern ( cheyne stokes respirations )
abnormal motor response ( decorticate or decebrate posturing )
what are the variable signs for late signs ( compensatory mechanisms failing )
HTN with widened pulse pressure
bradycardia
hyperthermia
terminal signs ( decompensation )
coma
- bilaterally fixed and dilated pupils
-respiratory arrest
- absence of motor response ( flaccid )
what are variable signs for terminal signs
HTN with widened pulse pressure
bradycardia
hyperthermia
what stage is this describing : this is too late to really do anything to treat them ( this pt will pass away )
terminal signs of s and s of iicp brain tries to compensate
the physicians and family will meet the criteria and they will consider organ donations ( if they are brain dead )
icp & cerebral perfusion pressure
what do u need to see a pt’s ICP and CPP in stepdown or ICU?
u need an icp monitor
icp and cerebral perfusion pressure
these patients would be on bedrest.
yes this is true they would be in bedrest
what is normal ICP ?
<15 mmHg
GCS<8 ‘coma ‘
if ICP > 20 ( there are problems )
relation between BP and CPP
normal CPP
may need to use meds to increase BP ( SBP goal ordered, ex: keep SBP 160 with meds )
the relation between BP and CPP, what do we need to understand.
we need to understand that it is because we need to know that perfusion has to keep up to the brain and keep them alive
IICP causes the brain tissue to receive inadequate perfusion, what do we do ?
want iCP at a level so that CPP is good and can perfuse brain tissues, Dr write medical order stating our goals.
what is a normal CPP ?
60-70 mmHg ( our goal is to keep it at 70 )
what is a prognosis for good recovery ? ICP and cerebral perfusion pressure
worst prognosis : longer patient is unconscious are high ICP
worst prognosis - likely never be tha same as before or ancient
how do we monitor neuro status?
icp and cpp
gcs ( eye opening, best verbal response, best motor response )/15 /how awake they are
recall that in our neuro assesment we are checking for the icp and cpp along with gcs ( eye opening, best verbal response, best motor response )/15 /how awake they are
what else?
clinical assessment - pupil size and reaction to light using pen light
true or false. Ct head/brain results - compare to previous CT what are we looking for ?
this is true and the bonus question is looking for that tightness
it is indeed true that recovery from a neuro injury takes time, what does this mean ?
recovery takes time ( process of waking up from a trauma )
they may be restless moving their arms and legs, eyes are starting to open
** key finding is if the pt can follow demands
( the doctor would like to know abt these findings )
What would cause a pt to have issues with IICP?
anything that can increase/cause cerebral edema
what would a patient who has issues with IICP ct scan look like?
brain looks tight and a shift ventricles looks collapsed
true or false. this could be an example of a pt who has issues with IICP : looks like the right or left side has shifted
of they may say ventricles have collapsed ( pressure pushing down to the ventricles )
this si true
recall that anything that can increase/cause cerebral edema can cause issues with IICP, what else?
- Head injury
- Assault/accident
- Subarachnoid hemorrhage (SAH) – spontaneous or fr an injury
- Meningitis (infection)
- Stroke (anoxic/ischemic problem)
- Brain surgery
what undergoes head injury that can cause increase in intracranial pressure ?
assault/accident - diffuse axonal injury
skull fracture
cerebral hematoma
contusion
moderate or severe brain injury
What are some things that cause or worsen IICP ?
A re bleed
seizure
pain/irritating issue
fever
coughing,straining ( valsalva maneuver )
true or false. increase in cerebral edema would require a repeated ct- and if the results come out that the brain looks tight and ventricles have collapsed , this can cause worsen IICP
this is true
If a pt has an icp monitor , what type of position are they on?
they are on bedrest, and still needs to be turned/repositioned q2-3 hours
IICP - nursing care, tx
what are we monitoring closely
vs, neuro,( pupils size, rx ) gcs, cpp, icp, 02 and c02 levels
posturing, any seizures
ICCP nursing care :
true or false. obtain parameters for BP from physician ( goal is SBP, gaol CPP induce HTN )
this is true
why we do give meds as a nursing care for IICP to induce HTN ?
we have to give meds to induce htn to make it higher in purpose to ensure blood flow getting to the brain cells
