this is used in dentistry with 2% solution with 1:20,000 levonordefrin as a vasoconstrictor

Back 3

mepivacaine

Front 4

this LA can be used plain because it produces less vasodilation than lidocaine

Back 4

mepivacaine

Front 5

less potent and less toxic than lidocain with a slightly longer duration and lower toxicity

Back 5

prilocaine

Front 6

this LA can lead to methemoglobinemia

Back 6

priolocaine (this is why not used for prego pt's)

Front 7

the amount of epinephrine in the LA is lowered (1:200,000)

Back 7

prilocaine

articaine

Front 9

which of the following could be classified as an amide and a ester

a contraindication for articaine is what?

Back 12

allergy for sulfa drugs

Front 13

none of these are administered by injection. usually topical

Back 13

esters

Front 14

this blocks norepinephrine reuptake resulting in vasoconstriction and hypertension.. can cause cardiac arythmias

Back 14

esters

Front 15

what is the most potent vasoconstrictor

Back 15

cocaine

Front 16

this is used as an antiarrhythmic agent and is combined with penicillin.. not used in dentistry today cuase of allergic reactions

Back 16

procaine

Front 17

this produces the greatest vasodilation of all of them

Back 17

this is 10 times more potent and toxic than procaine

Back 18

tetracaine

Front 19

Back 21

benedryl or diphenahydramine

Front 22

any anestetic without a vasoconstrictor is likely to be >>.

Back 22

toxic

Front 23

what does hemostatis mean? it happens with vasoconstrictors

Back 23

hemostasis

Front 24

what is the most common dilution rate for vasoconstrictors

Back 24

1:100,000

Front 25

only _ and _ are LA that are sold without vasoconstrictors

Back 25

mepivicaine and prilocaine

Front 26

maximum safe dose of vasoconstrictor for a healthy pt is how much?

Back 26

0.2mgs

Front 27

cardiac pts's can be given doses of how much epinephrine safely?

Back 27

0.04mgs

Front 28

the 2 most significant drug interactions with epinephrine are

Back 28

tricyclic antidepressants (result in high bp)
nonselective B-bloackers (may result in hypertention)

Front 29

duration of action is primarily related to

Back 29

its protein-binding capacity

Front 30

produce too much vasodilation to be used without a vasoconstrictor.

Back 30

Lidocaine and bupivacaine

Front 31

by injection near a bundle of nerves to induce anesthesia and relieve pain or spasms along several nerve pathways

Back 31

nerve block

Front 32
