Week 3--SPINAL CORD INJURY --(MR. LIEB)

Question 1

initial assessment of SCI

Answer 1

• NEUROVASCULAR ASSESSMENT
  
  • SENSORY (body to brain)
    
    • ex: dull/sharp sensations?
    • checking bilaterally (Spinal cord injuries typically present at bilateral, Stokes typically present at unilateral)
  • MOTOR (brain to body)
    
    • ex: may be weaker in one area
    • ex: “can you wiggle your fingers/toes”
  • DISTAL to PROXIMAL (start farthest away and work in)
  • Feet to head
• PAIN
  
  • absence of pain where you would anticipate pain
• Gastrointestinal (GI)
  
  • Initially, no peristalsis
  • Later-bowel movements may occur randomly
  • May be permanently relaxed “flaccid bowel”
• Genitourinary (GI)
  
  • Initially-flaccid bladder (distended-overfilled)
  • can empty-dribble out without warning
  • distension forces urine back into kidneys d/t incoordination of the bladder and urethral sphincter

Question 2

PRIMARY

INITIAL ASSESSMENT OF SCI

Answer 2

HINT: ABCDE

A-irway ^{(Protect the airway, respiratory support, suction secretions, etc)}

Question 5

Autonomic Dysreflexia

1. ) define
2. ) what causes it?

Answer 5

1. ) abrupt onset of excessively high blood pressure as the result of an overactive autonomic nervous system (ANS). occurs in clients who have injuries above level T5
2. ) triggered by irritation, pain or other stimulus below the level of injury, such as:
   - the urge to urinate/defecate ^{(overdistended bladder is the most common cause)}

-pressure sores

-burns

-pressure from tight clothing

• CONTUSION
  
  • ^{Bruising of neural tissue in grey matter}
  • **CAUSED BY CORD COMPRESSION-POSSIBLE PRESENCE OF NECROSIS
  • ^{often no long term complications}
• COMPRESSION

what type of signals does the ANTERIOR cord carry?

POSTERIOR?

Answer 15

ANTERIOR = MOTOR

POSTERIOR = SENSORY

Question 16

Anterior cord syndrome

• LOCATION OF INJURY
• Symptoms

Answer 16

• Injury to the anterior 2/3 of both the gray/white matter of spinal cord
• LOSS of MOTOR, PAIN, TEMP (below injury)
• PRESERVATION of POSITION, VIBRATORY
• WORST PROGNOSIS FOR RECOVERY

Question 19

iNJURY OF C4 to C5

(2)

Answer 19

• Diaphragm functional-NO intercostal functioning = RESPIRATORY INSUFFICIENCY

Answer 23

RESPIRATORY COMPLICATIONS

(Pneumonia)

• The only medication approved for the treatment of SCI?
• “4” important facts to know about this medication?

Answer 24

HIGH DOSE CORTICOSTEROIDS

Methylprednisolone (Solu-Medrol) IV

1. MUST be given in the first 8 hours after injury to be effective
2. Found to increase motor and sensory improvements over time
3. Weight-based dosing
4. NOT FOR PENETRATING INJURIES–d/t the risk for infection form

Answer 25

Hint: WIMP-HA ## Footnote **W**-eight Gain **I**-nfection **M**-ood swings **P**-eptic Ulcers **H**-yperglycemia **A**-vascular Necrosis

Question 26

What is Spinal shock? Due to what....... How long does it last.......? S/S......?

Answer 26

* Rapid to immediate onset of symptoms following a SCI. TEMPORARY LOSS of MOTOR, SENSORY and _REFLEX_ functions below the level of the lesion * **due to** inhibition of impulses in the spinal cord * **LASTS** for days to weeks * **CAUSES** Flaccid Paralysis ***_RESOLUTION IS NOTED WITH RETURN OF REFLEXES AND MUSCLE SPASTICITY_*** *_^{​Loss of motor and sensory functions can occur with any SCI, but loss of REFLEX is unique to SPINAL SHOCK. Deep Tendon Reflexes are NOT affected by SCI, unless the patient is in SPINAL SHOCK.} _*

Question 27

What is NEUROGENIC SHOCK...?

Answer 27

* Pt is at risk for POOR PERFUSION * Damage to T6 or higher * Causes disruption of sympathetic regulation of vagal tone (fight/flight)==WE HAVE ABUNDANCE OF PARASYMPATHETIC STIMULATION --Results in massive VASODILATION and decreased Vascular tone (resistance) ASSESSMENT FINDINGS: * BRADYCARDIA * HYPOTENSION * WARM, NORMAL COLOR SKIN-(b/c vasolation causing skin to get warm) * CORE TEMPERATURE INSTABILITY

Question 28

Can a patient with an injury at T 7 or below be in Neurogenic Shock?

Answer 28

NO. must be at T 6 or higher

Question 29

We recognize that the patient is bradycardic and hypotensive and is showing manifestations of Neurogenic shock. What medications would be given for the bradycardia? the Hypotension?

Answer 29

Atropine ....for the bradycardia vasopressors and fluids ....for the hypotension

Question 38

weak upper extremities with increasing strength as you get lower WHICH SPINAL CORD INJURY IS THIS?

Answer 38

Central cord syndrome

Question 39

\_\_\_\_\_\_ occurs when clients change position due to the interruption in functioning of the automatic nervous system and pooling of blood in lower extremities when in an upright position. "2" nursing interventions for this...

Answer 39

ORTHOSTATIC HYPOTENSION 1. Change the client's position slowly and place the client in a wheelchair that reclines 2. apply SCD/compression hose to increase venous return. May need to extend the compression to the abdomen using an abdominal binder

Question 40

This is the spinal cords response to inflammation caused by injury. Manifestations include: 1. flaccid paralysis 2. loss of reflexes 3. activity below the level of injury 4. paralytic ileus 5. loss of autonomic function\ 6. hypotension 7. bradycardia

Answer 40

SPINAL SHOCK \*\*KEEP MEAN ARTERIAL PRESSURE (MAP) AT LEAST 85MM hG CAN PREVENT FURTHER DAMAGE TO THE SPINAL CORD.
