anesthetic agents

Question 1

MOA

Answer 1

locally- inhibit N conduction by reducing the permeability of the nerve membrane to Na

Question 2

bupivacaine/marcaine

Answer 2

long acting anesthetic

Question 3

bicarbonate

Answer 3

• added to accelerate the anesthetic penetration- inc the % of non-ionized form
• diminishes the “sting” of the injection

Question 4

color of labels

Answer 4

blue- no epi

red- contains epi

Question 5

benzonatete/tessalon

Answer 5

local anesthetic & non-narcotic antitussive
MOA- numbs stretch receptors in the bronchus
PO- SOFT GELS- “tessalon pearls”

Question 6

minimum alveolar concentration(MAC)

Answer 6

• the measure of potency of an inhaled anesthetic

- volume % concentration of an inhaled anesthetic that is noted to have caused immobility in 50% of subjects

Question 7

malignant hyperthermia

Answer 7

-potential SE for all anesthetics
-unknown MOA
-causes pt’s muscles to become very ridged- results in a rise in pt’s body temperature to 105+
when suspected- anesthetic agent is immediately withdrawn
-ANTIDOTE- DANTROLENE- a sodium muscle relaxant, abolishes excitation-contraction coupling in muscle cells
