Traumatic SCI Flashcards
What is the primary function of the spinal cord?
Central relay for motor and sensory information between the brain and body
Also coordinates reflexes.
What are common causes of spinal cord injury (SCI)?
- Motor vehicle accidents
- Falls
- Acts of violence
- Sports injuries
Other potential causes include diving accidents and industrial mishaps.
What are the mechanisms of spinal cord injury?
- Cord Compression
- Penetrating Trauma
- Traction
- Laceration or Rupture
Each mechanism describes a different way the spinal cord can be damaged.
What does the location of a spinal cord injury determine?
Which body functions are affected
Location is defined by vertebral level or neurological level of injury.
What are the effects of a cervical injury at C4?
Affects breathing and may require ventilation
The C4 vertebra innervates the diaphragm.
What is the difference between complete and incomplete spinal cord injury?
- Complete: Total loss of motor and sensory function below the injury
- Incomplete: Some sensory and motor functions may remain
Incomplete injuries allow for the possibility of recovery.
What are the two types of spinal cord injuries?
- Primary Injury
- Secondary Injury
Primary injuries occur at the time of trauma, while secondary injuries develop after the initial injury.
What characterizes a primary spinal cord injury?
Occurs at the time of trauma and is usually permanent
It results from disruption of axons, blood vessels, and cell membranes.
What are some types of primary spinal cord injury?
- Cord compression
- Penetrating trauma
- Traction injury
- Laceration
- Rupture
Each type refers to a specific way the spinal cord can be damaged.
What defines a secondary spinal cord injury?
Ongoing damage after the initial trauma
Secondary injuries can occur from ischemia, edema, and microhemorrhages.
What are the effects of cervical injuries C1-C3?
Often fatal and will be ventilator dependent
These injuries result in paralysis of all four limbs (quadriplegia/tetraplegia).
What is spinal shock?
Complete but temporary loss of all motor, sensory, reflex, and autonomic function below injury
Usually resolves in 24-48 hours when deep tendon reflexes return.
What is the priority nursing intervention for spinal shock?
Maintain mean arterial pressure (MAP) at 85 or greater
This helps prevent ischemia.
What are common complications after cervical spine surgery?
- Breathing issues
- Pneumonia
- Bleeding
- Swallowing difficulties
These complications arise due to nerve involvement and reduced mobility.
What level of injury is associated with autonomic dysreflexia?
Damage at T6 and above
Autonomic dysreflexia is characterized by a sudden and dangerous increase in blood pressure.
What are the nursing goals in the field for an acute unstable spinal cord injury?
- Immobilize the patient
- Stabilize vital signs
- Transport to a trauma center
Immobilization prevents secondary injury and is crucial for patient safety.
Fill in the blank: The _________ test is always used to check neurological status in spinal cord injury.
[Dermatome]
It evaluates sensory function to determine the level of injury.
What should be monitored for SCI patients to prevent urinary tract infections?
- Proper catheter care
- Hydration
- Signs of infection (fever, cloudy urine, foul odor)
Effective monitoring can greatly reduce the risk of UTIs.
