Q

What does the FUNC score do?

When is it supposed to be used?

estimates the likelihood of functional independence 90 days after a diagnosis of ICH

used when the dx of ICH is made

Q

What is the common site of primary brain hemorrhage? What are ssx of disease here?

A

basal ganglia

CL hemiparesis, sensory loss, CL conjugate gaze paresis

17
Q

Most unruptured aneurysms are found where?

A

anterior circulation

18
Q

What aneurysm location has the highest risk of rupturing?

A

posterior or PCOM

19
Q

What presents with ‘worst headache ever’

A

SAH

20
Q

What is the Hunt Hess Grade?

A

Clinical survival scale

  • Grade 1
    • asymptomatic
  • grade 2
    • moderate to severe HA, nuchal rigidity, no neuro deficit except CN palsy
  • grade 3
    • drowsy, minimal neuro deficit
  • grade 4
    • stuporous, moderate to severe hemiparesis, possible early decerebrate rigidity and vegetative disturbances
  • grade 5
    • deep coma, decerebrate, moribund
21
Q

What is the radiographic spasm risk scale?

A

Modified Fisher Scale

  • MC complication of SAH is vasospasm (7-10 days sp)
  • predicted by severity of blood on scan
  • TCDs screen daily for vasospasm
22
Q

SAH is mostly diagnosed in the first 12 hours via CT, but if CT is negative, how can I dx SAH?

A

LP - presence of xanthochromia on CSF - nondiluting blood

absent after 14 days

23
Q

How do I treat SAH?

A

prevent re-bleeding (highest risk first 6 hours)

prevent vasospasm using nimodipine in all pts

endovascular coiling> surgical clipping of ruptured aneurysm

MAINTAIN EUVOLEMIA

24
Q

What three things can I fix to prevent poor outcome in my critical care brain injury pt?

A

fever, anemia, and hyperglycemia

25
Q

What complication can happen in most brain injuries? How do we tx this?

A

hypotonic hyponatremia

mannitol

26
Q

Should you ever give prophylatics for seizure med s/p brain injury

A

no

27
Q

cavernous malformations often present with…

What will this look like on imaging?

A

seizure or brain hemorrhage

popcorn or mulberry appearance

28
Q

What has dramatically helped reduce MM in SAH and ICH?

A

early surgery and optimal critical care management
