19
Q

Describe the SCI complication spinal shock?

A

absence of voluntary and reflexive activity below level of injury, lasts days-months

20
Q

Describe the SCI complication neurogenic shock?

A

-hemodynamic phenomenon including loss of vasomotor tone
- occurs within 30 min of injury T5 or above
- lasts up to 6 weeks

21
Q

Symptoms of spinal shock?

A
  • decreased reflexes
  • loss of sensation
  • flaccid paralysis below injury
22
Q

Symptoms of neurogenic shock?

A
  • hypotension
  • bradycardia
  • poikilothermia
23
Q

Intervention for neurogenic shock?

A
  • airway support
  • fluids PRN
  • atropine for bradycardia
  • vasopressors for BP
24
Q

Describe the SCI complication autonomic dysreflexia?

A

excessive uncontrolled sympathetic response, usually from noxious stimuli, occurs with SCI above T6

25
Q

Symptoms of autonomic dysreflexia?

A
  • severe HA
  • increase in BP
  • sweating
  • blurry vision
  • nausea
  • nasal congestion
26
Q

Interventions for autonomic dysreflexia?

A
  • sit pt up
  • call MD
  • antihypertensives
27
Q

Describe the SCI complication spasticity?

A

Increase in reflex activity and spasms, triggered by movement, pain, bladder etc.

28
Q

Symptoms of spasticity?

A

muscle spasms, increased reflex activity

29
Q

Interventions for spasticity?

A

medication, rehab program e.g. exercise, stretching

30
Q

What antihypertensive medications could be used to treat autonomic dysreflexia?

A

NTG, Apresoline, Prazosin

31
Q

What medication could be used to treat spasticity?

A

Baclofen
