Local Anesthetics Flashcards
List the Benzylisoquinolines
non depols
atracurium
cisatracurium
cisatracurium
tubocurarine
List the ammonio steroids
nondepols
pancuronium
rocuronium
vecuronium
which nondepol is short acting?
mivacurium
which nondepol is intermediate acting
atracurium
cisatracurium
rocuronium
vecuronium
which nondepol is long acting
tubocuraraine
pancuronium
kidney excreted or liver excreted have longer half lives
kidney - longer
liver - shorter
Name elimination mechanism for short acting mevacrium
plasma pseudcholinesterase
Name elimiation for atracurium intermediate
enzymatic and non enzymatic –> laudanosine – hypotension and seizures
Name elimination for intermediate cisatracurim
spontaneous and renal
name elimianation for intermediate rocuronium
hepatic 80% and renal
name elimination for vecuronium intermiediate
hepatic 80% and renal
name elimination for long pancuronium
renal 80% and hepatic
name elimination for long tubocurarine
renal and hepatic
i say laudanosine you think this nondepol and then you’d replace it with this nondepol
atracurium (hydrolyzed by non specific plasma esterase; not effected at renal failure) –< laudanosine can cause hypotension and seizures –> replace with cisatracurium that produces less laudanosine
how is mivacurium depol
only short acting
butyrylcholinesterase
not dependent on lvier or kidney
which is the most rapid onset?
rocuronium
a/se of benzylisoquinolines
hypotension bc they cause histamine release and ganglionic blockade
a/se of ammonio steroids
tachycardia due to blockade of muscarnic receptors - arrhtymias
i say histamine release and you think
benzyls
tubocurarine > mivacurium and atracurium
i say ganglion blockated and you think
tubocurarine = hypotension and tachycardia
i say blockade of cardiac M2 receptors and you think?
pancuronium - tachyca`rdia
a/se of depol blocker
stimulates nicotinic and muscarinic receptors
- bradycardia
- histamine release
- muscle pain
- hyperkalemia
- increased IOP
- increased intragastric pressure
who causese malignant hypertension and hwo do you treat it?
succinylcholine and haloperidol
tx with dan-tro-leenn
Spasmolytics MOA mania: diazepam
facilitates action of GABA at GABAa receptors
