Within the first 24 hrs of a spinal injury permanent damage can occur because of?
|
Edema
|
|
What results from edema in a spinal injury?
|
Compression of cord and increase in ischemic damage
|
|

|
Sympathetic nervous system
|
|

What is a secondary injury?
|
Happens after the main injury; ischemia, hypoxia, microhemorrhage, and edema
|
|
What are s/s of spinal shock?
|
- decreased reflexes
- loss of sensation - flaccid paralysis below level of injury |
|
How long does spinal shock usually last?
|
Few day to a few months
|
|
What does the sympathetic nervous system do?
|
Increases HR and contractility
|
|
What happens in neurogenic shock?
|
- loss of vasomotor tone caused by the injury
- Hypotension and bradycardia- hallmark sign |
|
What happens when you lose sympathetic nervous system innervation?
|
- peripheral vasodilation
- venous pooling - decreased cardiac output |
|
What is the most unstable type of injury? why?
|
- Flexion- rotation b/c ligaments in spine get torn
|
|
What is a skeletal level injury?
|
Injury is at the vertebral level, where most damage is to the vertebral bones and ligaments
|
|
What is a neurologic level injury?
|
Lowest segment of spinal cord with normal sensory and motor fuction on both sides of body
|
|
What are the 3 levels of injury?
|
- Cervical
- Thoracic - Lumbar |

Higher the injury the ________.
|
More severe
|

|
Phrenic nerve is at what vertebrae?
|
C3-C5
|
|
What results in complete cord involvement?
|
Results in total loss of sensory and motor function below level of lesion
|
|
What results in incomplete cord involvement?
|
Results in mixed loss of voluntary motor activity and sensation and leaves some tracts intact
|
|
Degree of sensory and motor loss depends on?
|
- Level of lesion
- specific nerve tracts damaged and those spread |
|

|
C7-T1 injuries will have control of? will lose control of?
|
- Control straightening their hands
- Have problems with dexterity of hand and fingers |
|
T1- T8 injuries will have control of? will lose control of?
|
- Control of head, neck, diaphram, arms, hands
- Poor trunk control due to poor abdominal muscle control |
|
T9- T12 injuries will have control of? will lose control of?
|
- allow good truck control and good abdominal muscle control. Sitting balance is very good
- No leg, bladder, bowel control |
|
L1- L2 injuries will have control of? will lose control of?
|
