myasthenia gravis
chronic autoimmune neuromuscular disease
causes muscle weakness
ptosis
eyelid droop
diplopia
double vision
dysphagia
trouble swallowing
dysarthia
slurred speech
myasthenic crisis?
not enough acetylcholine
severe muscle weakness and breathing
what is myasthenic crisis cured with?
neostigmine
cholinergic crisis
too much actylcholine
muscle weakness, difficulty breathing, excessive salivation, tearing, sweating and bradycardia
what is the cure for a cholinergic crisis?
atropine sulfate
what drug class is Mestinon?
choinesterase inhibitor
how does mestinon work?
prevents the destruction of acetycholine
enhances neuromuscular impulses
what are some conraindications of Mestinon?
GI obstruction
renal disease
peptic ulcer
what is the antidote for mestinon?
atropine sulfate
what are some side effects of mestinon?
increased peristalsis excess sweating blurred vision hypotension, bradycardia bronchospasm
nuring implications associated with mestinon
admin on time, before a meal, and assess for swallowing ability
how does flexeril work?
blocks skeleetal muscle interneural activity @ the brainstem
when is fexeril contraindicated?
cardiovascular disease, MAO inhibitors,
what are some side effects related to flexeril?
dizziness, drowzy, weakness bronchospasms, hypotension, tachycardia
what are some nursing implications associated with flexeril?
assess pain and ROM
