Exam 2: Spinal Cord Injury Flashcards
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)
What is the quad cough?
→ If they can’t cough and suctioning is not adequate, take hands and when then breath out, PUSH (below xiphoid)
→ Can implant pacemaker there to stimulate diaphragmatic contractions
What is autonomic dysreflexia?
(aka autonomic HYPERreflexia)
→ Life threatening
→ Noxious stimuli causes change in SYMPATHETIC NS
→ Below the level of injury
→ → Full bladder / UTI, bowel distension, impaction, constipation
→ → Circumferential compression - thorax, abd, scrotum, or extremities (tight clothing)
→ Temp
→ Pain / pressure
Name some symptoms you might see with autonomic dysreflexia (there are a bunch):
→ Sudden increase in systolic and diastolic BP
→ Bradycardia – reflexive bradycardia, body is trying to normalize. Due to increasing BP, might be tachy first
→ Severe HA
→ Nasal congestion
→ Diaphoresis (above injury) cold or goose bumps below
→ Flushed skin above the injury
→ Pale, goosebumps below the injury
→ Vasodilation above, vasoconstriction below
What are some diagnostics used with SCIs?
→ Dermatomes
→ X-ray (Identify fractures, subluxation, dislocation)
→ Spinal CT
→ MRI (CT and MRI can determine degree and extent of damage)
Re: Treatment for SCIs. What is something that we do that is non-surgical? Tell me a little about it.
Spinal cord stabilization
dislocation)
→ To maintain cervical alignment
dislocation)
→ Cervical collar
dislocation)
→ Halo
dislocation)
→ Skeletal traction (Realign vert, facilitate bone healing, prevent further injury)
dislocation)
→ Use “Log roll” – You should have 4 people!
What are some skeletal muscle relaxants used in SCIs (3)?
→Tizanidine
→ Cyclobenzaprine
→ Baclofen
What is some shit that they might do in surgery with a SCI?
→ May remove bone fragments, hematoma, penetrating objs
→ Wiring , insertion or rods, spinal fusion
Other meds used in SCIs?
Intrathecal baclofen
→ Given right at site of spinal cord injury
Steroids
Pain management
→ Gabapentin
→ Lyrica
→ NSAIDS
BP meds
Stool softeners
What kind of mattress do we want with SCIs?
FIRM. None of that specialty air mattress shit.
Talk me through a log roll with a spinal cord patient.
Turn pt w/o moving spine
→ Spine is to remain straight when getting out of bed
→ Should have 4 people
→ Person who has airway/c-spine calls when to start
What does BLT (mnemonic for SCI patients) stand for?
→ Bending - Avoid it. Bend at hips.
→ Lifting - No more than 5-10 lbs
→ Twisting - Nope. Shuffle and turn to look at something
