Cranial Nerve Disorders Flashcards
what causes trigeminal neuralgia
unknown - nerve root compression
which nerve is effected in trigeminal neuralgia
5th cranial nerve
s/s of trigeminal neuralgia
pain along side of nerve
is trigeminal neuralgia life threatening
no - high suicide rates
nursing dx of trigeminal neuralgia involves
pain
dx of trigeminal neuralgia
pt history and symptoms
may do hearing test
which type of drug therapy/class is used to trt trigeminal neuralgia
neuron depolarization
specific drug used to trt trigeminal neuralgia
tegretol - neuron depolarization
other trt methods used to trt trigeminal neuralgia
nerve blocking and biofeedback
surgical methods to trt trigeminal neuralgia
glycerol rhizotomy
per-cutaneous radio frequency
micro-vascular decompression
what happens in a glycerol rhizotomy procedure
lg needle - inject glycerol into trigeminal nerve root - paralyzes nerve root to stop pain impulses
how long will benefits from glycerol rhizotomy last
a couple months to years
what happens in a per-cutaneous radio frequency proc.
needle in trigeminal nerve root - apply heat to shrink
nursing mgmt for trigeminal neuralgia
Environmental mgmt - draft free
pen/note-pad at bedside
nutrition mgmt r/t trigeminal neuralgia
chewing causes pain - pt is likely afraid to eat
provide lukewarm foods - pt feeds self
strict i/o for nutrition concerns
oral care done by the patient
is pt awake during glycerol rhizotomy trt
yes - but completely numb (sedation can be provided)
if pt has several glycerol rhizotomy trts they can experience these symptoms
sensation concerns, corneal reflexes (corneal anesthesia) usually temporary
we recommend the use of electric razors with trigeminal neuralgia, t or f
true - wont cut self
good pt teaching w/trigeminal neuralgia
triggers - external stimuli - chew on unaffected side
which cranial nerve is affected by bells palsy
7th - thought to be related to herpes simplex virus
dx of bells palsy
exclusion - you’ve ruled out everything else
s/s of bells palsy
herpes vesicles behind the ears - place warm/cold pack
pharmacological trt r/t bells palsy
steroid - prednisone (quiets immune system)
zovirax/valtrex
eye care r/t bells palsy
dark glasses - night-time eye shield - taping lids
