Peripheral Nervous System Disorders Trigeminal neuralgia
Peripheral Nervous System Disorders
What is peripheral neuropathy?
denotes damage to nerves of the peripheral nervous system
Name 3 kinds of neuropathies.
What is mononeuropathy?
is a type of neuropathy that only affects a single nerve
What causes mononeuropathy?
often the cause is a localized trauma or infection
most common is physical compression of the nerve, (eg carpal tunnel syndrome)
interruption of blood supply (ischemia),
Name some common mononeuropathies?
carpal tunnel syndrome
“foot falling asleep” is a mild form of mononeuropathy
What is polyneuropathy?
neurological disorder that occurs when many nerves throughout the body malfunction simultaneously.
acute or chronic
What are some manifestations of polyneuropathy?
freq hands and feet are affected
sensory – decreased ability to feel hot/cold,
alt. or impaired sensation
impairment in autonomic systems
What causes polyneuopathy?
diabetes mellitus (most common)
excessive use of alcohol
What are some treatments for polyneuropathy?
treat the underlying disease
What is trigeminal neuralgia?
involving CN V (opthalmic/maxillary/mandibular)
usually middle to late life
pressure on nerve causes pain
What is visceral neuropathy?
impairment of the autonomic system nervers
What organs does visceral neuropathy affect?
Autonomic neuropathy can affect any of these organ systems:
lungs, blood vessels, bone, adipose tissue, sweat glands, gastrointestinal system and genitourinary system.
What are some s/s of visceral neuropathy?
depends on area of ANS involvement
loss of sense of bladder or bowel fullness
orthostatic hypotension (fainting when standing up)nausea
sluggish movement of the small intestine
urinary frequency, urgency, incontinence and retention
What are some of the organs affected by visceral neuropathy?
heart, lungs, blood vessels, bone, adipose tissue, sweat glands, gastrointestinal system and genitourinary system. Autonomic neuropathy can affect any of these organ systems.
What are some collaborative treatments for peripheral disorders?
effects usually not reversible
non specific treatment,
but meds may help (neurontin, lyrical, cymbalta)
nsg care aimed at prevention:
properly fitted shoes,
no bare feet,
assess skin of foot daily
toenails professionally cut
check temp of eater with hand or thermometer before putting feet in water
What are some s/s of trigeminal neuralgia?
severe facial pain
usually one sided
brief; seconds – minutes
remission can be a long period of time,
What causes trigeminal neuralgia?
cause is unknown
flu, trauma, infection, pressure on the nerve
What meds are used to treat trigeminal neuralia?
1. carbamazepine (Tegretol)
2. gabapentin (Neurotin)
What are some other treatments for trigeminal neuralgia?
keep journal to find triggers
possible triggers include:
chewing, cold, wind, shave, washing, putting on cream, etc.
What surgery is done for trigeminal neuralgia?
sever nerve but this leaves no sensation in cheek
What is Bell's palsy?
facial paralysis resulting from a dysfunction of the cranial nerve VII (the facial nerve)
inability to control facial muscles on the affected side
most common acute mononeuropathy
Who usually gets Bell's palsy?
20 - 60 year olds
What causes Bell's palsy?
No readily identifiable cause
sometimes occurs with other disease processes,
inflammatory condition leads to swelling of the facial nerve that block the nerve functioning
What are some s/s of Bell's palsy?
facial drooping on the affected half
: unable to control:
blinking and closing the eyes,
smiling, frowning, lacrimation,
salivation, flaring nostrils
What is the prognosis for Bell's palsy?
usuall self limiting, 3 weeks – 6 month
most recover completely
sometimes residual s/s,
sometimes sever residual s/s
What meds are used for Bell's palsy?
What are some nursing considerations for Bell's palsy?
prevent injury -chewing and biting mouth parts
artificial tears – eyes can't blink or protect itself,
massage for pain
sometime physical therapy
