S3_L5: Spinal Cord Injuries Flashcards
Pott’s Disease is AKA?
Tuberculosis of the spine
Determine whether spinal or neurogenic shock is described
- Flaccid paralysis
- Hypotension, bradycardia, and hypothermia
- Hypotension occurs after
- Vasopressors may be indicated for this
- In injuries above T6

Determine whether spinal or neurogenic shock is described
- Initial hypertension due to release of catecholamines
- Secondary to disruption of sympathetic outflow (T1-L2)
- Priapism may develop
- Bowel and bladder involved
- Loss of vasomotor tone

Determine whether spinal or neurogenic shock is described
- Symptoms lasting several hours to days
- Blood pressure will not be restored by fluid infusion alone
- Transient reflex depression of cord function below injury level
- Massive fluid administration may lead to overload and pulmonary edema
- Loss of cardiac sympathetic tone

What grading on the American Spinal Injury Association Scale is characterized by: Motor function preserved below level and power graded < 3?
Motor Incomplete
(first grade) or C
Note: This usually renders the patient unable to walk
What grading on the American Spinal Injury Association Scale is characterized by: No sensory or motor function preserved in sacral segments S4-S5?
Complete or A
What grading on the American Spinal Injury Association Scale is characterized by: Motor function preserved below level and power graded 3 or more?
Motor Incomplete
(second grade) or D
Note: This usually allows standing and walking
What grading on the American Spinal Injury Association Scale is characterized by: Sensory and motor function normal?
Normal or E
What grading on the American Spinal Injury Association Scale is characterized by: Sensory function is preserved but no motor function in sacral segments?
Sensory incomplete or B
Determine whether the injury described is a complete or incomplete SCI
- Loss of sensation & loss of voluntary movement of parts innervated by segment
- Some function is present below site of injury
- Recognizable patterns of injury, though they are pure and variations occur
- Favorable prognosis overall
- Spinal shock

A neurological disorder in which a fluid-filled cyst forms within the spinal cord, leading to a slow degeneration of the spinal cord from the center.
Syringomyelia
Note: The fluid-filled cyst is also called a syrinx
