What are the two things that determine spinal cord injury?
Mechanism of injury and location of trauma
What is primary injury vs secondary injury?
Primary = result of initial trauma
Secondary = result of ischemic/hypoxia/hemorrhage that destroys nerve tissues
For how long is secondary injury preventable for SCI?
first 4-6 hours after injury
What are the 6 types of injury that can cause SCI?
What type of injury is highly unstable and often occurs when patient falls on their head?
Axial rotational injuries
What injury causes vertebral bones to shatter or burst, and often occurs with blow to top of head or landing forcefully on feet?
Compression injuries
What injury is caused by backward bending of spinal column, e.g. fall when chin is point of impact?
Extension injuries
What SCI injury is most common and is caused by forward bending of spinal column e.g. head struck from behind?
Flexion injuries
What is quadriplegia defined by?
Patient with cervical level injury (C1-C7)
What is paraplegia defined by?
patient with injury from thoracic level (T1-T12) through to sacral level (S1-S5)
SCI Function varies depending on what?
vertebrae involved, e.g. injury to C1 vs injury to S5
Intermediate interventions for SCI?
ED interventions for SCI?
Example of an IV Corticosteroid used to treat SCI in ED?
Methylprednisolone
Neuro interventions for stabilised SCI?
Respiratory interventions for stabilised SCI?
Mobility interventions for stabilised SCI?
bowel/bladder function interventions for stabilised SCI?
Describe the SCI complication spinal shock?
absence of voluntary and reflexive activity below level of injury, lasts days-months
Describe the SCI complication neurogenic shock?
-hemodynamic phenomenon including loss of vasomotor tone
- occurs within 30 min of injury T5 or above
- lasts up to 6 weeks
Symptoms of spinal shock?
Symptoms of neurogenic shock?
Intervention for neurogenic shock?
Describe the SCI complication autonomic dysreflexia?
excessive uncontrolled sympathetic response, usually from noxious stimuli, occurs with SCI above T6
