Local and General Anesthetic Drugs Flashcards
Local Anesthetics are applied locally and block _ conduction
nerve
with local anesthetics _ function is loss first, followed by _ loss and _ and finally _ function
sympathetic
pinprick loss of sensation and temperature
motor
local anesthetics are _ and there use is followed by complete _
reversible
recovery
the commonly used local anethestics can be classified as _ or _ based on the linkage in this intermediate chain
esters or amides
the amide local anesthetics are chemically _ in vivo where’s the esters are ?
stable
hydrolyzed by plasma cholinesterase
ester local anesthetics
Cocaine, procaine, benzocaine, chloroprocaine, tertracaine
CBC Toilet Paper
amide local anesthetics
every other -caine
like lidocaine
MARBLE P
duration of action for ester local anethetics
C- medium
B-topical so doesn’t count
C- not given
Toilet- long
Paper-short
duration of action for amide local anesthetics
lidocaine is medium
mepivacaine is medium
rpoivacaine and buvicaine is long
articaine is medium
death from local anesthetics result from systemic absorption leading to respiratory failure secondary to _ depression or from hypotension and cardiovascular collapse
medullary
local anesthetics block the _ channel
Na+
some local anetherics have a _ effect resulting from termination of their action so a _ is added to increase duration of action and reduction of systemic toxicity
vasodilator
vasconstrictor
**lidocaine and cocaine
lidocaine is used IV also to treat _
cardiac arrhythmia
the state of anesthesia is a drug induced ?
absence of perception in all sensations
general anesthetics are administered primarily by _ and _
inhalation and IV
