DEFINITION
Insult to spinal cord resulting in a change,
in the normal motor, sensory or autonomic
function. This change is either temporary or
permanent.

motor paralysis with initial loss but gradual
recovery of reflexes, following a spinal cord

Spinal Shock vs Neurogenic Shock
Spinal Shock :
• Transient reflex depression of cord function below level of
injury
• Initially hypertension due to release of catecholamines
• Followed by hypotension
• Flaccid paralysis
• Bowel and bladder involved
• Sometimes priaprism develops
• Symptoms last several hours to days
Saturday, December 12, 2015 33
COPYRIGHT DR ALIHUSSEIN

Neurogenic shock:
• Triad of i) hypotension
ii) bradycardia
iii) hypothermia
• More commonly in injuries above T6
• Secondaryto disruption of sympathetic
outflow from T1– L2

• Loss of vasomotor tone – pooling of blood
• Loss of cardiac sympathetic tone – bradycardia
• Blood pressure will not be restored by fluid infusion
alone
• Massive fluid administration may lead to overload
and pulmonary edema
• Vasopressors may be indicated
• Atropine used to treat bradycardia

The pathology of hyper-extension injury
• Neck hyperextends (1)
• Stretching and tearing of the
anterior longitudinal ligament (2)
• Stretching of the cord (3)
• Nipping of the cord by
osteophytes (4)
• Stretching and kinking of spinal
vessels leading to spreading
thrombosis (5)
• Contusion and hemorrhage
inside the cord (6)
• Spontaneous reduction is the
rule, Xrays may be normal
• A tear drop fracture when
present may be the only tale-tell
sign, or a increased
retropharyngeal shadow

Clinical features of hyperextension injuries
• Diffuse cord damage that does not correspond with the level
of injury
• Anterior cord syndrome..motor paralysis
• Rarely central cord syndrome..and if so..mostly motor
signs… and lower limbs more severely affected than the
upper limbs

Diagnosis - radiology
X-rays:
AP and Lateral views, C7-T1 junction must be seen. If necessary be in the Xray
room to pull down the shoulders
Special views:
• Flexion / extension views to assess stability
• Oblique views will show the intervertebral foramina; good to assess
facetal locking, radicular symptoms and nerve roots compressions
• Open mouth views are good for assessing C1, C2 lesions
• CT-scan
• MRI scan

Initial Management of spinal cord injury
• Immobilization
– Rigid collar
– Sandbags and straps
– Spine board
– Log-roll to turn
• Prevent hypotension
– Pressors: Dopamine, not Neosynephrine
– Fluids to replace losses; do not overhydrate
• Maintain oxygenation
– O2 per nasal canula
– If intubation is needed, do NOT move the neck
Saturday, December 12, 2015 80
COPYRIGHT DR ALIHUSSEIN

Management in the hospital
• NGT to suction
– Prevents aspiration
– Decompresses the abdomen (paralytic ileus is common in the first
days)
• Foley
– Urinary retention is common
• Methylprednisolone (Solu-Medrol)
– Only if started within 8 hours of injury
– Exclusion criteria
• Pregnancy
• Age <13 years
• Patient on maintenance steroids

Decision to Intubate:
• Need for Artificial Airway is Usually Related to Resp Compromise e.g.
– Loss of innervation of the diaphragm
(C 3-4-5 keep the diaphragm alive)
– Fatigue of innervated resp muscles
– Hypoventilation
– V/Q mismatch
– Secretion retention
– Associated injuries
• Occiput - C3 Injuries
(ASIA A & B)
– Require immediate intubation
and ventilation due to loss of innervation of diaphragm

• Temporary suppression of all

• Occurs immediately after

• Once BCR returns, spinal
shock is over

• The body’s response to the

Hemodynamic State
Unopposed parasympathetic outflow can lead to cardiac
dysrhythmias and hypotension (most common within first
14 days)
• Hypotension is due to loss of

• Prevention:
– Avoid vagal stimulation

GI System
• Risk of aspiration is high d/t:
– cervical immobilization
– local cervical soft tissue
swelling
– delayed gastric emptying
• Parasympathetic reflex activity is altered,
resulting in:
– decreased gut motility and
– often prolonged paralytic
ileus.
• Minimizing Risk for
Aspiration:
–Nasogastric tube
• Minimizing Risk of Gastric
Ulceration:

• Meta-analysis showed insufficient evidence to support
use of high dose MPSS in ASCI as a treatment standard
or guideline for treatment.
• Weak clinical evidence to support MPSS as per NASCISNASCIS
II but not NASCIS IIIII but not NASCIS III protocol as an option for
treatment.

Cervical Traction
• Gardner-Wells tongs
• Provides temporary stability of the cervical spine
– Contraindicated in unstable hyperextension injuries
• Weight depends on the level (usually 5lb/level, start with
3lb/level, do not exceed 10lb/level)
• Cervical collar can be removed while patient is in traction
• Pin care: clean q shift with appropriate solution, then apply
povidone-iodine ointment
• Take XRays at regular intervals and after every move from
bed

Editor's Notes

  1. Resuscitation according to ATLS guidelines – you know this We will talk about Determination of neurological injury Prevention of neurological deterioration Ongoing ID &amp; Tx of assoc injuries Prevention of complications Initiation of definitive management for vertebral column injury or SCI
  2. Gabapentin not shown effective in Acute SCI
  3. Many of you are likely familiar with the use of Solumedrol post spinal cord injury to reduce the secondary injury associated with SCI
  4. Reference? In fact the Canadian Association of Emerg Physicians did a meta – analysis of NASCIS trials and found that there was weak clinical evidence to support the use of MPSS as a standard/guideline of treatment and recommend it as an option of care.
