SCI Goals of Care
There's no way to reverse damage
Treatment focuses on:
1. Preventing further injury
2. Enabling people to return to an active and
productive life within the limits of their disability
4
Treatment
Spinal Immobilization / Traction
High doses of corticosteroid drug
Methylprednisolone (Medrol) STAT !
must be within eight hours of injury
A few days after injury medical reassessment and
repeat of diagnostic tests will help determine the
severity of the injury and likely extent of recovery
Surgery as indicated

SCI Meds
Glucocorticoids (Decadron – suppress immune response)
Vasopressors (treat hypotension)
Plasma extenders (treat shock)
Atropine (treat bradycardia)
Muscle relaxants
Anti-Spasmodics (Dantrium)
Analgesics
Antidepressants
Zantac, Ranitidine (prevent gastric ulcers)
Stool Softeners
Vasodilaters (Hydralazine, nitroglycerin to treat HTN such as AD)
Anti-Seizure (gabapentin, phenytoin)
10
Neurogenic Shock
Occurs in acute stage of SCI (first hour per ATI)
Usually in injuries ABOVE T6
D/T interruption of the CNS …
…causing disruption of sympathetic outflow from T1 to L2
…with unopposed vagal tone
11
Neurogenic Shock: S & S’s
Warm and DRY skin… does not perspire on the paralyzed parts of
body d/t blocked sympathetic activity
Hypotension + Bradycardia + Hypothermia
(d/t vascular dilation …therefore blood pooling )
12
Spinal Shock
D/t concussive effect of the primary SCI on the nervous system
Can last days or months
Interferes with definitive diagnosis of permanent deficit
Effect causes temporary (transient) depression of all reflexes =
- paralysis (flaccid)
- loss of sensation
- loss of autonomic function
- loss of B & B control (Sometimes priapism)
Spasticity or hyperreflexia signals end of this shock
13
Autonomic Dysreflexia ( Hyperreflexia )
SCI acute syndrome of excessive uncontrolled
sympathetic output
Occurs ONLY after spinal shock has resolved
SCI above T6
Life-threatening HTN emergency
14
A. D. (Hyperreflexia)
Below T6 intact sensory nerves transmit noxious
impulses up the spinal cord…
…. BUT …
Sympathetic inhibitory impulses above T6
are blocked
THEREFORE
15
Sympathetic outflow continues…
causing release of norepinephhrine and dopamine
16
17
Result…
Severe Vasoconstriction
H/A + Sudden HTN
18
Result above the SCI…
Sweating + Flushing
19
Other Distinctive S & S
Bradycardia
Blotching of the Skin
Restlessness
Goose bumps
Stuffy nose (nasal congestion)
20
A.D. / Hyperreflexia
Clients with spinal cord injuries at Thoracic 6 – 10
(T6 -T10) may be susceptible
Patients with Thoracic 10 (T-10) and below are usually
not susceptible
The older the injury the less likely the person will
experience autonomic dysreflexia
21
Common Causes
The most common cause of noxious stimuli is
distension of the hollow viscera (80%), such as the
urinary bladder or bowel
1. Urinary Retention
2. Constipation
Simple kinks in the tubing or plugs in the urinary
catheter can trigger autonomic dysreflexia
22
Crede’s Method
Credé's method is a manual suprapubic pressure exerted with a clenched fist or fingers,
used to initiate micturition, in patients with spinal cord injury (SCI) who have
neurovesical dysfunction.
However, it is currently NOT recommended practice because of the risk of bladder
rupture.

23
Treatment…
Assist to sitting position to lower the BP through lowerextremity vascular pooling
Loosen restrictive garments (shirts, belts, slacks, straps and
even shoes)
Monitor Vitals
Look for Cause & Eliminate!
24
Treatment…
Ensure catheter patency (make sure catheter not kinked or pulled too
tight, and is actually draining urine)
Catheterize to decompress bladder
Assess for signs of urinary tract infection, such as dark, cloudy urine or
sediment in catheter tubing
If bowel is distended, disimpact after inserting anesthetic jelly or
ointment per rectum
Hypertension should be treated medically if it persists
25
Still Can’t Find Cause ? !!!
Cause may not be readily found…
Careful physical exam is imperative during this crisis
Other causative agents usually not considered in medical
emergencies include skin irritations, wounds, pressure sores,
burns, broken bones, pregnancy, ingrown toenails, appendicitis,
and other medical complications
Still cannot find cause? ….
focus on decreasing the blood pressure!
26
Antihypertensive Meds
Nifedipine (Adalat) 10 mg orally - instruct the patient to
bite the capsule, then swallow it
Nitroglycerin sublingual or topical paste (1/2 inch)
Prazosin (Minipress)
Clonidine (Catapres) 0.1- 0.2 mg PO
Hydralazine (Apresoline) 10 - 20 mg IM/IV
27
Client Teaching
• Provide education about early recognition and treatment of
A.D.
• Encourage the client to carry some type of medic alert
identification
(It is estimated that approximately 85% of spinal cord injury patients at level T-6 will
suffer at least one episode of autonomic dysreflexia)
28
Client Teaching
Prevention:
Frequent pressure relief in bed/chair
Avoid sun burn/scalds (avoid overexposure, use of #15 sunscreen,
watch water temperatures)
Faithful adherence to bowel program
Keep catheters clean and remain faithful to catheterization schedule
Well balanced diet and adequate fluid intake
Compliance with medications
29
SCI Recovery
Recovery typically starts between a week and six
months after injury, if it occurs, with the majority of
recovery taking place within one year
Doctors generally regard any impairment remaining
after 12 to 24 months as likely to be permanent

32
SCI Rehabilitation
Initial rehabilitation emphasizes regaining leg and arm strength,
redeveloping fine-motor skills and learning adaptive techniques to
accomplish day-to-day tasks
Then long-term rehab typically includes exercise and training with:
Modern wheelchairs - Improved, lighter weight wheelchairs are
more mobile and more comfortable. The Food and Drug
Administration has even approved a wheelchair that can climb stairs
and elevate a seated passenger to eye level to reach high places without
help
Computer devices - Computer-driven tools and gadgets can
help with daily routines. Voice-activated computer technologies to
answer and dial a phone, or to use a computer and pay bills. Computercontrolled technologies can also help with bathing, dressing,
grooming, cleaning and reading
33
34
Complications
Urinary tract problems - urinary incontinence increases risk of
urinary tract infections, kidney infection, kidney or bladder stones. d/t
ongoing catheterizations
Bowel management difficulties – Reduced peristalsis and fecal
incontinence
Pressure sores - particularly susceptible to pressure sores because the
injury reduces or eliminates sensations, making it difficult to know when a
sore is developing
Deep vein thrombosis and pulmonary embolism
Lung and breathing problems - Difficult to breathe and cough
with weakened abdominal and chest muscles, so people with cervical and
thoracic spinal cord injury may develop pneumonia, asthma or other lung
problems
35
Complications…
Spasticity – some people develop muscle spasms and
jumping of their arms and legs because some of the nerves
in the lower spinal cord become more sensitive after injury
and cause muscle contractions. However, because of the
spinal cord injury, the brain can no longer send signals to
the lower nerves to regulate the contractions
Weight control issues - Weight loss and muscle atrophy
are common. But the change in lifestyle and activities may
eventually cause weight gain, which can make it difficult
for the pt lift themselves — or be lifted — from place to
place
36
Concerns
Pain
- It's possible to feel pain in areas where there's little or no
sensation
- May also experience pain from overusing muscles in one part
of the body. Many people develop shoulder tendinitis from
manually operating a wheelchair for a long period of time
- Any kind of pain can have a negative impact on daily living
.
New Injuries
- Susceptible to injury of any part of the body that has impaired
sensation
- May even receive a burn or cut without realizing it
37
Male Concerns…
Sexual Dysfunction
Still have erections, even with little sensation in the genital area
But erections may not be firm enough or last long enough for sexual
activity
Fertility also can be affected:
- 99% aren't able to ejaculate during intercourse
- Low sperm counts
- Poor sperm motility
***** However, men can be sexually active and father a child
38
Female Concerns…
Sexual Dysfunction
• Most have no physical change that inhibits sexual intercourse
or pregnancy
• But may lose ability to produce vaginal lubrication or control
vaginal muscles
• Many experience changes in body image that affect sexuality
• Any pregnancy will likely be considered high risk
• There may be amenorrhea for about 6 months after SCI
39
Coping
Grieving
Healthy part of recovery. It's natural and important to grieve the loss of the way the
person was before. Then…necessary to set new goals and find a way to move forward
with life
*** Depression and alcohol abuse***
Taking control
Education about injury and options for reclaiming an independent life
Because the costs can be overwhelming, find out about economic assistance or
support services from the state or federal government or from charitable
organizations
Talking
Friends and family may respond in different ways
