Q

Crani surgery post-op care 1

A
  • Meningitis (#1 culprit)
    • prophylactic ABx
    • assess drain/incision sites
  • Respiratory problems
    • encourage IS/deep breathe, but NOT coughing
    • prepare room for suctioning
  • Seizures
21
Q

Crani surgery post-op: CSF leak

A

call MD and check for glucose

22
Q

Crani surgery post-op: IICP

A
  • proper positioning (consider drains and location of surgery)
  • no restraints or enemas
23
Q

Crani surgery post-op care: Trans-sphenoidal

A
  • damage to CN III common, assess visual field loss or deterioration
  • monitor I/O, assess for DI
  • call MD for excessive drainage
24
Q

Trans-sphenoidal pt. education

A
  • avoid (4 weeks): blowing nose, coughing, sneezing, straws, bending over, straining on toilet
  • no driving for 2 weeks
25
Left-frontal lobe tumor expected findings
personality/judgement/emotional changes
26
Swallow problems interventions
- high Fowler's position - chin to chest - reduce distractions
27
Penumbra
area surrounding the minimally-perfused dead core, ability to save depends on timely re-circulation, volume of toxins released by dead cells, degree of edema
28
Stroke Risk Factors
- TIA (warning sign) or previous stroke - HTN - A-Fib - Heart disease - DM - Oral contraceptives - smoking, obesity, sedentary lifestyle - hyperlipidemia/atherosclerosis
29
TIA
temporary stroke symptoms, thrombotic stroke, few minutes up to 24 hours, neuro deficits are reversible (find out baseline from family)
30
Ischemic vs. Hemorrhagic Stroke
- ischemic most common (87%), can be thrombotic or embolic | - hemorrhagic usually caused by HTN
31
Thrombotic AIS
- atherosclerosis #1 risk factor - vessels: lose elasticity, harden, narrow - symptoms: sudden, often during sleep or in morning - may be gradual process (buildup)
32
Embolic AIS
- A-Fib #1 risk factor - travelling blood clot lodges in small vessels or middle cerebral artery - sudden onset of symptoms
33
Hemorrhagic Stroke
- vessel integrity interrupted (bleeding into tissue or subarachnoid space - CT STAT to find/rule out bleed
34
Middle Cerebral Artery (MCA)
- most often occluded in a stroke | - largest branch of internal carotids
35
MCA Stroke S/Sx
hemiparesis, sensory loss (face/arm > leg), gaze deficits (eye deviation), aphasia
36
Anterior Cerebral Artery Stroke
Presents with motor/sensory loss (leg > arm)
37
Hemorrhagic Stroke: Arterio-Venous Malformation
- looks like vessels are tangled/clumped - congenital anomaly - age 10-40 - surgery: ligation (vasospasm/rebleed)
38
Hemorrhagic Stroke: SAH
- cerebral aneurysm leak or burst - bleeding occurs in sub-arachnoid space - tests find: blood on LP, aneurysm on CT/MRI - most common symptom: "worst HA I've ever had"
39
Ruptured Aneurysm S/Sx
- sudden, extremely severe HA, photosensitivity (also for meningeal tumor) - change in LoC - blurred/double vision - drooping eyelid - seizure
40
Unruptured Aneurysm S/Sx
- pain above and behind one eye - dilated pupil - change in vision/double vision - unilateral facial numbness
41
Code Stroke Protocol
- last known well time - complete assessment with NIH scale - blood sugar - CT - IV start with blood draw - report any changes immediately
42
Time is Brain Protocol
- 3-4.5 hour window from onset of symptoms - CT non-contrast within 25 min to r/o bleed - bleed: hemorrhagic/no bleed: ischemic - screen for tPA - begin fibrinolytic Tx
43
tPA (alteplase)
- ischemic only (gold standard) - dissolves the clot - given 24 hours after onset of Sx
44
SAH Tx
- endovascular therapy/coiling - surgical aneurysm clipping - medical Tx
45
SAH Complications
- rebleed - vasospasms - hydrocephalus
46
Cerebral Vasospasm Management
- balloon angioplasty - nimodipine 60 mg q4h for 21 days - SBP 160-200 if clipped or 120-150 if unclipped - central venous pressure 10-12 mmHg
47
Nimodipine
- SAH/cerebral vasospasm treatment - calcium channel blocker - reverses body's immediate reaction to vasoconstrict (would lead to further damage) - allows blood to flow more easily to non-damaged tissue
48
Post-Stroke Interventions
- ALWAYS clarify MD's desired parameters for BP | - usual maintenance level 120-150
