What is another name for Spinal Shock? |
|
Definition
|
|
Term
What is Spinal Shock (areflexia) |
|
Definition
Immediate response to acute spinal cord injury.
Loss of all spinal cord function including sympathetic reflex activity (muscles, vessels & viscera) below the level of the injury. |
|
|
Term
How long does Spinal Shock (areflexia) last? |
|
Definition
|
|
Term
Clinical manifestations of Spinal Shock (areflexia)? |
|
Definition
Decreased BP, decreased pulse, hypothermia.
Flaccid paralysis below injury.
No sensation below injury.
Bowel & bladder retention.
Respiratory failure in injury above C6
Unable to perspire below level of injury- body can't cool itself, can lead to heat stroke.
|
|
|
Term
Evidence of Spinal Shock (areflexia) resolution? |
|
Definition
Muscle spasms (possible), reflex emptying of bowel & bladder. |
|
|
Term
What is another name for Autonomic Dysreflexia? |
|
Definition
|
|
Term
What is Autonomic Dysreflexia (hyperreflexia)? |
|
Definition
Occurs with injury above T6 after spinal shock phase is over.
Stimuli --> massive sympathetic reflexive discharge from autonomic system --> catecholamine released --> vasoconstriction. |
|
|
Term
Stimulis resulting in Autonomic Dysreflexia (herperreflexia)? |
|
Definition
Most common: BOWLE or BLADDER distention.
Pressure Ulcers
Ingrown toenail
Pt too hot or cold
UTI, kidney stones
Any pain/discomfort/local injury |
|
|
Term
Clinical manifestations of Autonomic Dysreflexia (hyperreflexia)? |
|
Definition
HTN (massive, life threatening)- 300/150 mmHG.
Bradycardia in response to massive HTN (to decrease CO to decrease BP).
Pounding HA, blurred vision, nausea.
Nasal congestion in some.
Sweating above level of injury.
Cyanosis below level of injury r/t vasoconstriction.
Anxiety, goosebumps, flushing, chills w/o fever. |
|
|
Term
Management of Autonomic Dysreflexia (hyperreflexia)? |
|
Definition
Prevention is most effective.
Prompt recognition.
Need emergent tx! - will cause CVA! |
|
|
Term
Treatment of Autonomic Dysreflexia (hyperreflexia)? |
|
Definition
First priority- Check foley for kinks/ bowel & bladder distention. (If present, use anesthetic & cath pt or remove stool)
HOB up 90 degrees to decrease BP.
ID & remove other immediate causes.
Give meds if already ordered, or call MD to order med stat (apresoline, hyperstat, nipride IV; nifedipine SL)

What are vertebrae disks?
(A&P) |

Term
What is the pulposus of a disk?
(A&P) |
|
Definition
|
|
Term
What is the annulus of a disk?
(A&P) |
|
Definition
A fibrous ring around the disk. |
|
|
Term
Herniated disks usually occur where? |
|
Definition
Usually affects the cervical or lumbar disks. |
|
|
Term
What is a Herniated Disk? |
|
Definition
|
|
Term
Risk factors associated with Herniated Disks? |
|
Definition
Aging: degeneration of disks.
H2O content in disks dereases --> Small cracks form in annulus --> Annulus weakens & nucleus pulposus pushes out.
Trauma.
Severe or repeated minor injury causes weakened annulus allowing nucleus pulposus to protrude.
|
|
|
Term
Who is more prone to Herniated Disks? |
|
Definition
Obesity & poor posture & poor body mechanics cause increased weight load & predispose to injury.
Smoking has a difinite link- vasoconstriction causes decreased circulation. |
|
|
Term
Clinical manifestation of Herniated Disk? |
|
Definition
Vary depending on level of injury.
Pain, weakness, paralysis, numbness, tingling radiating down arm or leg over distribution of nerve root.
Pain increases with straining, coughing & lifting because disk bulges more r/t increased CSF pressure in spinal column.
Eventually walking & sitting becomes difficult.
Loss of bowel & bladder control. |
|
|
Term
Diagnosis of a Herniated Disk? |
|
Definition
MRI (most often) or CT.
Straight leg raises (lie supine & raise one leg with knee straight = increased pain).
Rarely myelogram (MRI noninvasive & better).
EMG to evalute nerve impulses. |
|
|
Term
Goals of treatment for Herniated Disk? |
|
Definition
Rest & immobilization of spine to allow soft tissues time to heal.
Decrease inflammation of soft tissue & nerve roots. |
