What are the effects of neuromuscular blockers?
|
Paralyze only skeletal muscle (not visceral smooth muscle)-can't move or breath, but heart and GI muscle can function; no effect on CNS-no analgesia or sedation.
|
|
What are some precautions to take when using a neuromuscular blocker?
|
Admin after induction of general anes, intubate & ventilate patient, monitor for hypothermia & lubricat eyes.
|
|
What are some uses for neuromuscular blockers?
|
Thoracic, orthopedic or opthalmic surgery. Reintubation in laryngospasm. Not used much in vet med, mostly human.
|
|
What is a type of neuromuscular blocker?
|
Succinycholine.
|
|
What is succinycholine used for?
|
A neuromuscular blocker.
|
|
What does succinycholine do to the muscle?
|
It's a nondepolarizing muscle paralyzer
|
|
What are some characteristics of succinycholine?
|
Muscle twitch, followed by paralysis, fast onset, short duration, no reversing agent-must wear off.
|
|
How does succinycholin work?
|
It replaces acetylcholine at receptor & prevents receptor activation.
|
|
How do depolarizing muscle paralyzers work?
|
They compete with acetylcholine at receptor site.
|
|
Dooes succinycholine have a reversing agent?
|
No
|
|
Do depolarizeing muscle paralyzers have a reversing agent?
|
Yes, neostigmine.
|
|
Do neuromuscular blockers paralzye skeletal or visceral smooth muscle?
|
Skeletal.
|
|
Do neuromuscular blockers have an affect on the CNS?
|
No, there's no analgesia or sedation.
|
|
What do you need to use with neostigmine?
|
Pre-treat with Atropine.
|
|
What are 5 types of neuromuscular blockers?
|
Succinylcholine, depolarizing muscle paralyzers, gallamine, pancuronium bromide & curare.
