acute consequences of sci

weakness with a caudal injury leads to

htn or hypotension in acute phase of sci?

A

hypotension

4
Q

urinary ___ in acute phase of sci

A

retention

5
Q

Acute consequences of SCI? (5)

 quadriparesis/plegia (neck) paraparesis/plegia (caudal)

Sensory loss or abnormalities

Hypotension

Urinary retention


Orthopedic pain 

6
Q

chornic consequencies of sci? (10

A

1. involutnary mvoements

2. bladder problems

3. decreased bowel motiblity

4. sexual dysfunction

5. increased risk fo blood clots

6. pressure ulcers

7. autonomic dysfunction

8. metabolic disorders 

9. musculoskeltal breakdown/fracures

10. psych

7
Q

above T10 injury , bladder problems are 

A

spastic/neurogenic bladder (most common).

 

Can’t voluntarily relax the external urethral sphincter, so it stays tight as bladder fills.

8
Q

below T12, bladder sx are 

A

 flaccid bladder, can’t contract for emptying

9
Q

management of flaccid bladder 

A

manage using...intermittent catheterization, condom catheter, indwelling/Foley
catheter, or suprapubic catheter 

10
Q

male sexual dysfunction? 

A

Male, sperm viability is impaired / fertility is impaired. 

11
Q

female sexua problems? 

A

Female, fertility is mostly unaffected but C-section delivery strongly recommended (b/c of autonomic dysreflexia)

12
Q

Pressure ulcers from __

A

cutaneous ischemia

13
Q

Autonomic Dysfunction: sympathetic damage = impaired ___

A

thermoregulation

14
Q

* Autonomic Dysreflexia with SCI =

A

 extreme blood pressure swings (240/160) + low heart rate

15
Q

what causes autonomic dysreflexia? 

A

occurs in response to strong afferent input, ex. pain or overly full bladder

16
Q

what can happen with repeated occurenced of autonomic dysrefelxia? 

A

chronic hypertension

17
Q

metabolic disorders with spi are often due to

A

lifestyle difficuluties

18
Q


___ sp injuries/year

A

10,000-12,000

19
Q

> 50% of injuries are to ___ spine

A

cervical

20
Q

> 50% are neurologically “incomplete” - means there is sensation

A

in S4-S5 region.

21
Q

“complete” means bilateral injury with total loss of 

A

sensation below injury level

22
Q

ASIA scale: A is ___ injury

A

complete/worst injury

23
Q

ASIA sale B-D is ___

A

incomplete

24
Q

ASIA scale e is __

A

 is normal

25
Q

Three approaches to SCI treatment:

 

A

1. Neuroprotection of surviving cells/axons from toxic injury environment

2. Neurorestoration via replacement cells, neurotrophins, and establishing a growth-
permissive environment


3. Neurorehabilitation by strengthening existing systems and retraining circuits

26
Q

 methylpredinisolone (steroids) trials results

A

1. found higher mortality in higher tx group

2. another found asia scale improvement in pts who were incomplete, 24 hr dosing

3.  48 hr dosing beter

27
Q

parapesis/plegia occurs caudal to __

A

t1

28
Q

for___that are crushed by the intial truamtic injury nothing can be done those are gone for food 

A

 nerve cell bodies 

29
Q

among pts who started tx ___ of injury the 48 MP group receovered signfiicantly more funciton at 6 weeksn and 6 months than those with 24 MP

A

3-8

 

30
