Spinal Cord Injury (SCI)

A
  • A major health problem
  • 276,000 persons in the U.S. live with disability from SCI
  • 17,000 new cases per year
  • Trauma is leading cause which include MVAs (35%), violence (24%), falls (22%), and sports injuries (8%)
  • Males account for 80%
  • Ages 16 to 30 account for more than half of all new SCIs
  • Risk factors include alcohol and drug use

Q

Primary

A
  • The result of concussion, contusion, laceration or compression of spinal cord
  • Primary injury is the result of the initial trauma and usually permanent
  • Treatment is needed to prevent partial injury from developing into more extensive, permanent damage

Q

Secondary

A
  • Secondary injury is usually the result of hemorrhage, ischemia, hypovolemia, hypoxia, local edema and which destroys the nerve tissues
  • Secondary injuries are thought to be reversible/ preventable during the first 4 to 6 hours after injury
  • Treatment is needed to prevent partial injury from developing into more extensive, permanent damage

Q

Emergency Management

A
  • Proper handing of patient
  • Consider head/neck trauma
  • Rapid assessment Immobilization
  • Extrication Control of life-threatening injuries
  • Transport to the appropriate facility
  • Pharmacologic Therapy IV Corticosteroids (methylprednisolone sodium succinate [Solu-Medrol]) (Controversial)
  • Respiratory Therapy
  • Fractures
  • Surgical Management
  • The patient’s vital organ functions and body defenses must be supported and maintained until spinal and neurogenic shock abates and the neurologic system have recovered from the traumatic insult; this can take up to 4 months.

Q

Cardiovascular Assessment

A
  • Cardiovascular dysfunction is usually the result of disruption of the autonomic nervous system especially if the injury is above the 6th thoracic vertebra.
  • Cardiac dysrhythmias may result.
  • Systolic BP below 90 requires treatment because lack of perfusion to the spinal cord could worsen the patient’s condition.
  • Hypothermia.
  • Assess for Venous Thromboembolism
  • Never massage an immobile patient due to danger of dislodging a clot

Q

Lab and Imaging Assessment

A
  • ABG’s

21
Q

Sensory and Motor Assessment

A
  • Motor ability is tested by asking the patient to spread the fingers, squeeze the examiner’s hand, and move the toes or turn the feet.
  • -Sensation is evaluated by gently pinching the skin or touching it lightly with an object such as a tongue blade, starting at shoulder level and working down both sides of the extremities. The patient should have both eyes closed so that the examination reveals true findings, not what the patient hopes to feel. The patient is asked where the sensation is felt.
  • Any decrease in neurologic function is reported immediately.

28
Q

Surgical Management

A

Surgery is indicated in any of the following situations:
- Compression of the cord is evident.
- Injury results in a fragmented or unstable vertebral body.
- The injury involves a wound that penetrates the cord.
- Bony fragments are in the spinal canal.
- The patient’s neurologic status is deteriorating.
- The patient’s vital organ functions and body defenses must be supported and maintained until spinal and neurogenic shock abates and the neurologic system have recovered from the traumatic insult; this can take up to 4 months.

29
Q

Immobilization for Cervical Injuries

A
  • Fixed skeletal traction to realign the vertebrae, facilitate bone healing, and prevent further injury
  • Stryker frame, rotational bed, kinetic treatment table
30
Q

*Spinal Shock

A

Spinal shock – occurs immediately after injury
- A sudden depression of reflex activity below the level of spinal injury
- Flaccid paralysis of skeletal muscles, complete loss of sensation, Pulse, BP suppression of somatic (pain, touch, temp,) and visceral reflexes
- Bowel and bladder function affected.
- *Need to maintain MAP at 85 or higher
- cause by the swelling of the spine
- shock of spinal cord itself

31
Q
  • Neurogenic shock
A
  • Due to the loss of function of the autonomic nervous system below the lesion.
  • Vital organs affected causing a decrease in Blood pressure, heart rate and cardiac output
  • Venous pooling occurs due to peripheral vasodilation
  • Paralyzed portions of the body do not perspire
  • shock of nervous system
  • distributive
32
Q
A
33
Q

Spinal shock s/s

A

Definition:
- Immediate temporary loss of total power, sensation, and reflexes below the level of injury
- BP: hypotension
- Pulse: bradycardia
- Bulbocaverosus reflex: absent
- Motor: flaccid paralysis
- Time: 48–72 hours immediate after SCI
- Mechanism: peripheral neurons become temporarily unresponsive

34
Q

*Neurogenic shock

A

Definition:
- sudden loss of sympathetic nervous system signals
BP: hypertension
Pulse: bradycardia
Bulbocarvernosus reflex: variable
Motor: variable
Time: 48 - 72 hours immediate after SCI
Mechanism: disruption of autonomic pathways

35
Q

Treatment for Shock

A
  • Maintain adequate hydration via IV and oral if possible
  • Vasopressors, supportive care.
  • Observe for manifestations of neurogenic shock
  • *May occur within 24 hours after injury most commonly in patients with injuries above T6.
  • Monitor hourly V/S including pulse ox and symptoms of aspiration, decreased LOC, decreased urine output
  • Notify MD immediately as this is an emergency.
    — neurogenic shock
36
Q

Drug Therapy

A
  • Dextran – plasma expander
  • Anticholinergic - Atropine sulfate
  • Vasopressors
  • Adrenergic Drugs - Epinephrine and nor epinephrine
  • Muscle Relaxants
37
Q

Autonomic Dysreflexia

A
  • Acute emergency
  • Occurs after spinal shock has resolved and may occur years after the injury
  • Occurs in persons with a SC lesion above T6
  • Autonomic nervous system responses are exaggerated
  • Triggering stimuli include distended bladder (most common cause), distention or contraction of visceral organs (such as constipation), or stimulation of the skin
    — too tight of a shirt/ belt, socks/ shoes
    — laying on a syringe
    — full bladder/ bowel
    — blankets on top that are too heavy
  • teach them s/s to look out for
38
Q

Autonomic Dysreflexia

A

Spinal cord injury at T-6 or higher:
- Triggered by sustained stimuli at T-6 or below from:
— restrictive clothing
— pressure areas
— full bladder, or UTI
— fecal impaction

S/S:
- Increased BP (severe and rapid)
- Flushed face
- Headache
- Distended neck veins
- Decreased HR
- Sweating
- Vasodilation above injury
- Vasoconstriction below injury
— pale, cool, no sweating

39
Q

Autonomic Dysreflexia 2

A
  • Sudden, significant rise in systolic and diastolic blood pressure, accompanied by bradycardia
  • Profuse sweating above the level of lesion—especially in the face, neck, and shoulders; rarely occurs below the level of the lesion because of sympathetic cholinergic activity
  • Goose bumps above or possibly below the level of the lesion
  • Flushing of the skin above the level of the lesion—especially in the face, neck, and shoulders
  • Blurred vision
40
