Spinal Cord Injuries
 Life
expectancy greatly increased since
WW II.
 Intermittent
catheterization
 Medications, equipment, etc
 Cause
of premature death in QUADS is
usually related to COMPROMISED
RESPIRATORY FUNCTION
Spinal Cord Injuries
 Who’s
at risk?
 ADULT
MEN BETWEEN 15 AND 30
YEARS
 Anyone in a risk-taking occupation or
lifestyle
 SCI
in older clients increasing largely
due to MVAs
Spinal Cord Injuries
 Causes
(in order of frequency)
 MVA
 Gunshot
wounds/acts of violence
 Falls
 Sports
injuries
Spinal and Neurogenic Shock
 Below
 Total
site of injury:
lack of function
 Decreased or absent reflexes and flaccid
paralysis
 Lasts from a week to several months after
onset.
 End of spinal shock signaled by muscular
spasticity, reflex bladder emptying,
hyperreflexia
Classification of SCI
 Mechanism
 Flexion
of injury
(bending forward)
 Hyperextension (backward)
 Rotation (either flexion- or extensionrotation)
 Compression (downward motion)
Pathophysiology of SCI



Cervical (C-1 through ??)
Thoracic (T-1through ??)
Lumbar (L-1through ??)
Degree of Injury

Complete


Total paralysis and loss of sensory and motor function
although arms or rarely completely paralyzed
Incomplete or partial

Degree of Injury
 Complete

transection
Total paralysis and loss of sensory and motor
function although arms or rarely completely
paralyzed
 Incomplete
(partial transection)
Mixed loss of voluntary motor activity and
sensation
 Four patterns or syndromes

Incomplete cord patterns
 Insert
picture of cord here
 Central cord syndrome More common in
older clients
Frequently from hyperextension of spine
 Weakness in upper and lower ext, but greater
in upper.

 Anterior
cord syndrome
 Posterior cord syndrome
 Brown-Sequard syndrome
Anterior cord syndrome
 Compression
of the ant. Cord, usually
a flexion injury
 Sudden, complete motor paralysis at
lesion and below; decreased
sensation (including pain) and loss of
temperature sensation below site.
 Touch, position, vibration and motion
remain intact.
Posterior cord syndrome
 Assoc
with cervical hyperextension
injuries
 Dorsal area of cord is damaged
resulting in loss of proprioception
 Pain, temperature sensation and motor
function remain intact.
Brown-Sequard syndrome

Damage to one half of the cord on either side.
 Caused by penetrating trauma or ruptured
disk. ischemia (obstruction of a blood vessel),
or infectious or inflammatory diseases such
as tuberculosis, or multiple sclerosisBSS may
be caused by a spinal cord tumor, trauma
(such as a puncture wound to the neck or
back),.
 a rare SCI syndrome which results in


weakness or paralysis (hemiparaplegia) on one
side of the body and
a loss of sensation (hemianesthesia) on the
opposite side.
Clinical manifestations of SCI
 Depend
on the LEVEL and DEGREE of
the injury!
 Quadriplegia occurs with C-1 through
C-8 injuries.
 Paraplegia occurs with T-1 thru L-4.
 SEE TABLE 57-3 ON PAGE 1725!
Clinical Manifestations of SCI
 Respiratory
– C3: Absence of ability to breathe
independently.
 C4 – poor cough, diaphragmatic breathing,
hypoventilation
 C5 – T6: decreased respiratory reserve
 T6 or T7 – L4: functional respiratory
system with adequate reserve.
 C1
What is the phrenic nerve?

The phrenic nerve stimulates the diaphragm
to contract.
 Two phrenic nerves (right and left) - injury to
one or the other paralyzes contraction of only
one half of the diaphragm but even hemi(half) paralysis can significantly interfere with
breathing for patients with lung disease.
 The nerve arises from branches of the C3,4,
and 5 nerve roots.
 The phrenic nerve can be damaged by
procedures exploring the neck & upper back

Loss of the phrenic nerve on either side
results in paralysis of the diaphragm on that
side.
 Paralysis of the diaphragm on one side
results in less inflation of the lung on that
side.
 Whether this is physiologically significant
(producing respiratory distress,
hypoventilation/hypercapnia) depends on
other aspects of a patient's pulmonary
physiology (namely underlying chronic
obstructive pulmonary disease [emphysema,
bronchitis], pneumonia, etc.).
Cardiovascular system
– T5 shows decreased or absent SNS
influence.
 BRADYCARDIA AND HYPOTENSION
(due to vasodilation)
 C1
What is the VAGUS nerve?
 The
longest of the cranial nerves- exits
out of the medulla and ends in the
abdomen
 It supplies sensory and motor function
to the pharyngx
 Supplies motor function to the muscles
of the abdominal organs
 Provides parasympathetic activity to the
heart, lungs, and most of the digestive
system
Urinary System
 Atonic
bladder with RETENTION in
spinal shock.
 Post acute phase – irritability causing
dribbling or frequent urination.
 Urinary infection and calculi from
retention and distention.
 INTERMITTENT CATHETERIZATION!
GI system

Decreased motility
 Paralytic ileus
 Gastric distention – intermittent NG suctioning
 Increased H2 – administer H2 inhibitors such
as Zantac or Pepcid in initial stages
 Carafate and antacids later as prophyaxis
 Intraabdominal bleeding! Remember, no pain
or tenderness to warn you.
 Watch for H/H decrease and impactions
Integumentary System
 Pressure
ulcers!
 Muscle atrophy in flaccid paralysis
 Contractures in spastic paralysis
 Poikilothermism – the adjustment of
body temp to room temperature
 Decreased ability to sweat below lesion
Peripheral vascular system
 DVT
common but not detected easily
 Pulmonary embolism a significant cause
of death.
 Doppler studies, measurement of
extremity girth, impedance
plethysmography (what the heck is
this?)
Post Injury Assessment

Goals are to



Sustain life
Prevent further cord damage
Assessment of muscle groups; motor status




Against gravity
Against resistance
Both sides of the body
Ask to move legs, hands, fingers, wrists, then
shrug shoulders
Post injury assessment (p.1726)
 Thorough
motor examination including
position sense and vibration.
 Sensory examination
 Pinprick
starting at toes and working
upward
 ALWAYS HAVE CLIENT CLOSE EYES OR
LOOK AWAY! If he can see what you’re
doing, he will answer accordingly.
 Assess
for head injury and ICP
 X-ray, CT scan, EMG
Surgical Therapy
 Reduces
 Done
injury and stabilizes the SC
for
 Compression
 Bony
fragments in the cord
 Compound fracture
 Penetrating trauma
Drug Therapy
 Vasopressors
(Dopamine) to keep
mean arterial pressure greater than
80mm to 900mm/Hg so that
PERFUSION TO CORD is improved.
Methylprednisolone (Solu-medrol)
 Increases
the recovery of function and
is the SOC! IV bolus then continuous IV
over a 23 hour period.
 Improves
blood flow and reduces
edema in the SC
Other drug therapy
 Symptom-reducing
 GI
drugs for
problems - zantac, tagamet, pepcid
 Bradycardia - atropine
 Hypotension - vasopressors
 bladder spasticity - anticholinergics
 autonomic dysreflexia – blood pressure
reduction
