Q

how are SCI neurological level named?

  • sensory
  • motor
A

Neurological level named for lowest functional level (normal sensory/motor)
• Normal sensory
• MMT 3/5 (fair) and the immediately proximal level is at 5/5 (normal)
• Can vary between left/right sides of body

Q

what pathology? mechanism?
- onset 3-6 days s/p severe SCI, trauma
• sympathetic loss
• hypotension
• Immediate, TEMPORARY loss of power, sensation,
and reflexes below the lesion (and possibly above)
• Temporarily unresponsive to stimuli, flaccid paralysis
• Bowel/bladder flaccidity, loss of bulbocavernosus reflex (S2-4)

A

spinal shock syndrome

- due to inflammatory process, edema fills spinal canal

Q

symptoms of autonomic dysreflexia? first steps when you see patient with the symptoms?

A

symptoms: above SCI injury - vasodilation, flushed face, pounding headache, increased BP, decreased HR, increased sweating distended neck veins
below level of SCI - vasoconstriction, pale, cool, no sweating
next step - sit up patient (decrease blood to head avoid hemorrhagic stroke), quick check for noxious stimulus, activate EMS

Q

what is orthostatic hypertension? what next to do?

A

drop 20mmHg SBP or 10mmHg DBP moving supine to sit/stand or on tilt table

  • next step lay supine or trendelenburg to get blood flow back to head
  • use tilt table to build up threshold
  • “head is pale, raise the tail”

25
what is brown sequard syndrome injury? | what is affected - motor, pain/temp, discriminatory sensation
hemisection spinal cord - ipsilateral below lesion - motor (corticospinal), fine touch/proprioception/vibration (DCML) - decussate at medulla - contralateral below lesion - pain and temp (spinothalamic)
26
prognosis brown sequard
good
27
prognosis central cord
average
28
prognosis anterior cord
poor
29
cause of brown sequard?
penetrating trauma - gunshot, stab wound
30
cause of central cord?
forced hyperextension eg. MVA
31
cause anterior cord
forced flexion or vascular trauma
32
central cord affects what?
sensory and motor loss cervical (more central than sacral) UE > LE difficulty with hand function
33
anterior cord affects what?
- incomplete SCI, anterior 2/3 of SC - complete all loss of motor (corticospinal) below level of lesion - all pain, temp below injury (spinothalamic) - maintain proprioception and vibration (DCML spared)
34
micturition control what spinal level?
bladder control S2-4
35
lesion above L1/conus medullaris leads to what kind of bladder? how is it managed?
spastic/hyperreflexic bladder - Reflex arc intact, reflexively empties with adequate filling pressure - no voluntary control -manage w intermittent catheterization initially, suprapubic tapping without dyssynergia
36
lesion below L1/conus medullaris leads to what kind of bladder?
flaccid/areflexic bladder - unable coordinate between detrusor and sphincters - managed with catheter or Valsalva maneuver training
37
lesion above S2 leads to what kind of bowel? how is it managed?
Spastic/reflexic bowel | • Reflex defecation when rectum fills or Digital stimulation
38
lesion below S2 leads to what kind of bowel? how is it managed?
Flaccid/areflexive bowel • Manual evacuation • gentle Valsalva maneuver
39
