Complications of Immobility In SCI-
Integumentary
Integumentary:
Pressure ulcers
Spinal Cord Injury (SCI)Causes
MVA Falls Violence Other/unknown Sports related accidents
What Happens in SCI?
Injury occurs to either:
Vertebrae & ligaments
Blood vessels
Damage to vertebrae ligaments, blood vessels makes spinal cord unstable increasing possibility of compression or stretching of cord with further movement.
Rarely is spinal cord completely severed.
SCI
Primary?
Primary injury to the spinal cord
The initial mechanical disruption of axons.
SCI
Secondary
Secondary injury to the spinal cord
The ongoing, progressive damage that occurs to spinal cord neurons from:
Further swelling
Demyelination
Necrosis
Edema extends level of injury 2 cord segment levels above and below. Extent of injury cannot be determined for up to one week.
Paralysis
Paralysis
Partial or complete loss of muscle function
Complete SCI
Complete SCI:
Complete interruption of motor & sensory pathways
Results in total loss of motor & sensory function below level of injury
Incomplete SCI
Incomplete SCI:
Partial interruption of motor & sensory pathways
Variable loss of function below the level of injury
Paresis
Paresis
Partial paralysis/weakness.
What is Upper Motor Neurons responsible for?
Upper Motor Neurons
Responsible for voluntary movement.
Upper Motor Neurons
Injury leads to?
Injury leads to: Increased muscle tone/ spastic paralysis Decreased muscle strength Inability to carry out skilled movement Hyperactive reflexes.
What are the Lower Motor Neuron responsible for?
Lower Motor Neuron Responsible for innervation and contraction of skeletal muscles.
Lower Motor Neuron
Injury leads to?
Injury leads to:
Decreased muscle tone
Muscle atrophy/ flaccidity/weakness
Loss of reflexes.
Loss of voluntary & involuntary movements.
Partial to full paralysis depending on how many motor neurons affected.
Some or All motor neurons effected, what happens?
If only some of the motor neurons supplying a muscle are affected only partial paralysis is experienced.
If all motor neurons to the muscle affected= complete paralysis and hyporeflexia.
Paraplegia
Damage to thoracic, lumbar or sacral area of the cord.
Loss or impairment of motor and /or sensory function the trunk, legs, and pelvic organs.
Arms are spared
T6 level injury= use of arms & upper chest
L1 level injury use of all but legs.
Full independence in self care in w/c.
Sacral Sparing
Some incomplete SCI patients experience this phenomenon where sensation is preserved in sacrum. Positive finding!
Patients with sacral sparing, then, may have fewer problems with bowel functioning and elimination than those with a complete injury.
Sacral Sparing
results in?
Results in: Bowel & bladder training possible Perianal sensation Rectal function Highest possibility of sexual function
Sacral Sparing
Bowel training with sacral sparing
Bowel training: Digital stimulation, stool softeners, suppositories High fiber high fluid diet Upright position Assess usual patterns
Sacral Sparing
Bowel training without sacral sparing
Bowel Maintenance without Sacral sparing:
Digital removal, enemas
Abd. massage to stimulate peristalsis.
Sacral Sparing
Teaching
Teach:
Home self cath=clean technique
Voiding triggers:
Stroke inner thigh
Pull on pubic hair
Tap on abdomen
Pour H20 over vulva
Crede, manual pressure on the abdomen at the location of the bladder, just below the navel.
Monitor residual urine <80 ml ok
Highest level of sexual function in sacral sparing patients.
Most people with SCI can have satisfying sexual relationship regardless of the level of injury
Tetraplegia
Tetraplegia
(Quadriplegia). Cervical damage causing loss or impairment of motor and/or sensory function in the arms, trunk legs and pelvic organs.
Tetraplegia
C1-C4
C1-C4 injury C1-C2 injuries could result in death Often fatal at scene Respiratory paralysis common Require ventilator assistance. Head and neck movement only Require 24 hour care. Cannot live independently May use an electric wheel chair with mouth stick, and head rest.
Tetraplegia
Below C4 and C6
Below C4
May not be ventilator dependent
C6
Shoulder movement
IM Injections in SCI
I.M. injections should be given above the level of injury.
Clients with spinal cord injuries have reduced use and reduced blood flow to muscles (ventral gluteal) and legs (vastus lateralis).
IM Injections in SCI
decreased blood flow to muscle?
Decreased blood flow to muscle can result in:
Impaired drug absorption
Increased risk of local irritation and trauma
May result in ulceration of the tissue.
Autonomic Dysreflexia
what is it?
What is it?
Exaggerated sympathetic response in SCI patient’s at or above T6 level injuries.
Triggered by stimuli that normally causes abdominal pain.
Autonomic Dysreflexia
Pathophysiology
Pathophysiology:
Stimuli is unable to ascend the cord.
Causes stimulation of sympathetic nerves below level of injured cord resulting in massive vasoconstriction.
Vagus nerve causes bradycardia & vasodilation above level of injury.
Autonomic Dysreflexia
triggers?
Triggers: Full bladder (most common) Fecal impaction Pressure ulcers Dressing changes Ingrown toenails Surgical procedures Labor contractions
Autonomic Dysreflexia
S/S
Signs & Symptoms:
Pounding HA
Bradycardia & HTN (high as 240/120 risk of CVA)
Vasodilation with warm flushed skin & profuse sweating above level of injury.
Pale, cold (gooseflesh), dry skin below level of injury
Neurologic Emergency!!!!!
Autonomic Dysreflexia NI
1st Raise HOB/ sit patient up!!!
Identify cause (full bladder, bowel?)
Remove stockings or boots to decrease b/p.
Best intervention is through prevention.
May be hypotensive after stimulus removed.
**Bladder and bowel are most frequent causes of AD.
Complications of extremely high blood pressure
Complications of extremely high blood pressure: Loss of consciousness Seizures Death Stroke
Halo Traction
External fixation device
Used to provide stabilization if no significant involvement of ligaments.
Stability for fracture of the cervical and high thoracic vertebrae without cord damage.
4 pins inserted into the skull & ring attached to plastic vest.
Halo Traction
Pro’s
Pro’s
Greater mobility
Self-care
Participation in rehab programs
Halo
Nursing Interventions
Inspect pin & traction sites for looseness.
Never use halo ring to reposition patient.
Assess sensation
Pin care per agency policy.
Turn immobile patients q 2 h
Tape wrenches to HOB for emergency intervention.
Straws for drinking, cut food small pieces
Monitor fatigue and balance
Assess skin under vest
Do not drive
Amputations defined
Definition:
Partial or total removal of an extremity.
Amputations causes?
Causes:
PVD- primary reason
PVD risk factors: smoking, DM, HTN, hyperlipidemia.
Peripheral neuropathy (loss of sensation leads to injury)
Untreated infections.
Trauma (MVA, machinery accidents).
Amputations
post-op complications
Post-op Complications: Infections Hemorrhage Delayed healing Phantom limb pain Contractures
