ALS & GBS - 405 Flashcards
ALS
a relentlessly progressive, presently incurable neurogenerative disorder that causes muscle weakness, disability & eventually death
median survival is 3-5 years
ALS CM
-asymmetric limb weakness (upper = hand weakness or shoulder girdle, lower = foot drop)
-fatigue
-dysarthia/dysphagia
-muscle atrophy & spasticity
-fasciculations (twitching) of face or tongue
-respiratory muscle weakness
cognitive function stays in tact but body wastes away
drug therapy for ALS
riluzole: only FDA approved for ALS, not curative but extends survival time
exercise & ALS
guide pt through moderate intensity endurance type exercises for trunks / limbs to reduce spasticity
care of ALS
-consults (slp & pt)
-NPO
-pain assessments
-minimize risk for injury
-facilitate patient and family anticipator grieving
Guillain Barre Syndrome
acute, immune mediated polyneuritis - a progressive (ascending) fairly symmetric muscle weakness accompanied w/ absent or depressed deep tendon reflexes
can range from mild difficulty walking to nearly complete paralysis
w/ GBS where does paresthesia usually occur
hands & feet
w/ GBS where is pain usually located
back & extremities
GBS dysautonomia
-tachycardia
-labile blood pressure
-orthostatic hypotension
-ileus
-urinary retention
autonomic nervous system
what usually precedes GBS
a viral infection, immunization, trauma or surgery
dx of GBS
-H&P
-cerebrospinal fluid (only after one week of onset): will show inc protein & normal WBC
-nerve conduction studies & needle EMG
GBS plan of care
-astute, routine physical assessment (disease can progress rapidly and pt can end up on a vent)
-assess gag & corneal reflexes
-frequent VS
-possible dysphagia diet if needed
-pain mgt (neuropathic)
-monitor for urinary retention
plasmapheresis
removes circulating antibodies, complement & soluble biological response modifiers
-4 to 6 treatments over 8 to 10 days
GBS main modalities of therapy
-plasmapheresis
-IVIG
administer within 4 wks of onset
GBS prognosis
-95% survive
-75% completely recover
-25-30% have residual weakness after 3 years
-3% may suffer relapse of muscle weakness & tingling many years post initial attack
