Peripheral Nerve and Spinal Cord Problems Flashcards
Trigeminal Neuralgia
CN 5
etiology: compression of superior cerebellar artery, Herpes virus infection, tooth infection, brainstem infarct
Trigeminal Neuralgia Manifestations
Pain: face (around eyes, nose, mouth, cheeks)
twitching
blinking
tearing
severe pain has been r/t suicide
-cold air, water, face washing, tooth brushing, talking, eating can all cause pain
Trigeminal Neuralgia Dx Studies
Dx by exception
CT, MRI, EMG, CSF
Trigeminal Neuralgia Collaborative Tx
Drug therapy: anti seizure meds (slow firing of nerves)
Conservative tx: nerve block; biofeedback
Surgical tx
Trigeminal Neuralgia Nursing consideration/teaching
eating - soft foods, avoid really hot/cold foods or drinks
hygiene - soft towels, soft toothbrushes
environmental concerns - scarves
Bell’s Palsy
Disruption of CN 7: sensory and motor
etiology: Herpes Simples Virus; 85% full recovery within 6 months
Motor function test
smile, puff out cheeks, frown, raise eyebrows
Sensory function test
taste
Bell’s Palsy manifestations
Herpes vesicles in or around ear and Fever are seen together
Tinnitus (close proximity to CN 8 - acoustic)
Hearing deficit
Paralysis of motor branches of facial nerves (taste loss on affected side)
Bell’s Palsy Dx studies
Pattern and Onset
EMG
Want to r/o Stroke (similar manifestations)
Bell’s Palsy concerns
eating, aspiration risk, corneal abrasion b/c of not being able to close the eye
Bell’s Palsy Tx
moist heat
electrical stimulation - if not recovering
prevention of complications: eye drops to keep moist and take eyelids shut at night
Drug therapy: corticosteroids to reduce inflammation to nerve
Antiviral agents to treat herpes (acyclovir)
Guillian-Barre’ Syndrome
Acute, rapidly progressing polyneuritis; loss of myelin, edema and inflammation of the affected nerves; cell mediated immunological rxn
Guillian-Barre’ Syndrome Manifestations
Preceded by URI or GI infection
Paralysis of lower extremities and works it’s way upwards
Parasthesia
Pain
Progressive paralysis includes thoracic area, facial weakness, extra ocular eye movement, dysphagia
- most cases are reversible but will take months to return to normal
Guillian-Barre’ Syndrome Dx Studies
dx by exception
CSF and EMG
