Exam 2: Spinal Cord Injury Flashcards
(35 cards)
What is the most common area of injury?
C5
What are the 2 types of SCI?
Complete → damage that eliminated all innervation below injury
Incomplete → injury allows some function below injury
Which type of SCI is more common?
Incomplete
What are the two causes of SCI (very general terms)
Primary → initial injury
Secondary → effect after initial injury that worsens the primary injury
Describe what is happening with hyperflexion (this is PRIMARY).
Head comes forward
Describe what is happening with hyperextension (this is PRIMARY).
Head goes backwards
Describe what is happening with axial loading / vertical compression (this is PRIMARY).
Pushed down (football players get this a lot)
Describe what is happening with excessive rotation (this is PRIMARY).
Twisting
Describe what is happening with penetrating trauma (this is PRIMARY).
It’s a penetrating trauma.
Ex: Nails in back
YIKES
Describe what is happening with distraction (this is PRIMARY).
Pulling away from neck (up)
Ex: Hanging
What are some examples of secondary causes of SCI?
- Hemorrhage
- Ischemia
- Hypovolemia
- Impaired tissue perfusion
- Edema
The higher up injury = the more ________ symptoms.
Severe
You see CV issues when the injury is above ___.
What issues do you see?
Above T6
→ Bradycardia
→ Hypotension
→ Dysrhythmias
When the injury is ____ you see respiratory issues.
Cervical
“C3, C4 breathe no more”
What are dermatomes?
Zones of sensory motor function
→ Utilized as part of assessment
What are myotones?
Zones of muscle function
Plegia =
Paralysis
Tetraplegia / quadriplegia =
Complete paralysis of all 4 extremities
Paraplegia =
Lower extremity paralysis
Paresis =
Weakness
Quadriparesis =
Weakness in all 4 limbs
Paraparesis =
Weakness in lower extremities
Talk to me about spinal shock.
→ Occurs immediately after injury
→ Not a real “shock”
→ Has temp complete loss of motor sensory reflex and autonomic function
→ Lasts ~48 hrs, can last weeks
→ Typically occurs within 24 hours of injury, lasting up to weeks
→ Loss of spinal cord function below level of injury
Respiratory compromise occurs due to innervation of the _________ __________ (controls diaphragm).
Phrenic nerve
(Remember: Respiratory compromise = cervical injuries at C3-C5)
