Questions And 100% Verified Answers.
Intracranial hemorrhage's goal for treatment?
Stop bleeding. Decrease icp.
Subdural hematoma?
bleeding between covering of brain (dura) and surface of brain.
Compress brain tissue , leadin to brain dead. Most pt do not
recover.
Transcranial doppler (TCD)?
ultrasound that measures velocity of blood flow in brain.
Perfusion CT?
IMAGING THAT SHOWS PERFUSION AREAS OF BRAIN.
WHAT IS IN A NEURO ASSESSMENT?
Pupil size, shape, equality and reactivity, Level of
consciousness, orientation and appropriateness, sensory and
motor function, visual changes, cranial nerve function,
intracranial and cerebral perfusion pressures,
,ventriculostomy drainage. neurological status of this patient
population may wax and wane throughout the period of
vasospasm
WHAT IS IN THE "TRIPLE H THERAPY"?
HYPERTENSIVE , HYPERVOLEMIA, HEMODILUTION.
Hypertensive therapy.SBP >160 mm HG.Don't treat BP -
patients will usually auto regulate. Hypervolemia. Maintain
PCWP > 12. Hemodilution.IV fluids at 100-150 ml per hour.
Hematocrit 33-38% *Think of it this way: if you're trying to push
more liquid (blood) through a tube (a cerebral artery) that is
tightening up (spasm) there are three things that you can do: 1.
You can push harder - hypertension. 2.You can load up the
tube with more liquid - hypervolemia. 3.You can make the
liquid less viscous so it slides through more easily -
hemodilution
TERSON SYNDROME?
vision loss that maybe reversible in SAH pt.
Venoplasty/ dural venous sinus stenting?
stent to the narrow part of venous sinus. Allow blood to pass
through more easily. Thus, lower pressure inside head. Anti
clot meds post procedure.
, WHAT ARE THE THREE CLASSES OF CEREBRAL ANEURYSMS?
SACCULAR/BERRY ANEURYSM - ROUND AT BRNACHES OF
ARTERY, MOST COMMON IN ADULTS. FUSIFORM ANEURYSM -
ROUND LOCATED AT THE SIDES OF ARTERY. MYCOTIC
ANEURYSM - ANEURYSM CAUSED BY INFECTION, WEAKEN
ARTERY WALL. LEAD TO BULDING OF ARTERY.
Spinal angiogram?
view the blood vessels (aorta) that surrounds the spine.
Catheter starts at femoral artery.
Idiopathic intracranial hypertension (pseudotumor cerebri)?
high icp without an intracranial mass. Cause is unknown. Best
treatment is dural venous sinus stenting/ venoplasty.
Transient ischemic attack (TIA)?
a type of stroke. Lack of blood (ischemic) to brain for a short
period of time 1-2hrs then gone.
What is the most common type of stroke?
acute ischemic stroke (AIS).
