Term
Structurally related to acetylcholine, used to produce muscle paralysis in order to facilitate surgery or artificial ventilation. Full doses lead to respiratory paralysis and require ventilation |
|
Definition
Neuromuscular blocking drugs |
|
|
Term
These drugs strongly potentiate and prolong effect of neuromuscular blockade (NMB) |
|
Definition
Inhaled anesthetics, especially isoflurane, aminoglycosides, and antiarrhythmic |
|
|
Term
These prevent the action of ACh at the skeletal muscle endplate to produce a "surmountable blockade," effect is reversed by cholinesterase inhibitors (ex. neostigmine or pyridostigmine) |
|
Definition
Nondepolarizing type antagonists |
|
|
Term
Agent with long DOA and is most likely to cause histamine release |
|
Definition
|
|
Term
Non-depolarizing antagonist has short duration |
|
Definition
|
|
Term
Agent can block muscarinic receptors |
|
Definition
|
|
Term
Agent undergoing Hofmann elimination (breaking down spontaneously) |
|
Definition
|
|
Term
One depolarizing blocker that causes continuous depolarization and results in muscle relaxation and paralysis, causes muscle pain postoperatively and myoglobinuria may occur |
|
Definition
|
|
Term
During Phase 1 these agents worsen the paralysis by succinylcholine, but during phase II they reverse the blockade produced by succinylcholine |
|
Definition
Cholinesterase inhibitors |
|
|
Term
MOA of non-depolarizing drugs |
|
Definition
Act at Nicotinic receptors by competing with ACh |
|
|
Term
Initial effect of Depolarizing Drug |
|
Definition
|
|
Term
Characteristics of NM blocking drugs |
|
Definition
highly polar, poorly lipid soluble |
|
|
Term
Causes hypotension due to histamine release |
|
Definition
Tubocurarine and Mivacurium |
|
|
Term
Causes cardiac arrhythmias when with halothane anesthetics; Stimulates Autonomic cholinoreceptors (Negative inotropic and chronotropic) |
|
Definition
|
|
Term
Adverse effects of depolarizing agents |
|
Definition
Hyperkalemia, Increased intraocular pressure, increased gastric pressure and muscle pain |
