what are the 2 chemical classifications of dental anesthetics
ester
amide
ester anesthetic undergo biotransformation where
blood plasma
amide anesthetic undergo biotransformation where
liver
what is the most commonly used topical anesthetic
benzocaine or lidocaine
what is the most commonly used dental anesthetic in the US
2% lidocaine
what anesthetic provides the longest duration
.5% bupivicaine (marcaine)
which anesthetic is classified as an amide but metabolized more like an ester
articaine (septocaine)
what is a vasoconstrictor
a substance that causes vasoconstriction, which is the narrowing of blood vessels (increased BP)
what are the effects of adding a vasoconstrictor
prolongs anesthetic
reduces toxicity
decreases blood loss
what are the two types of vasocontrictors
epi (adrenaline)
levonordefrin (neo-cobefrin)
what is the anesthetic most likely used without a vasocontrictor
topical - benzocaine
what is the safe dose of epi for a healthy adult
.2mg
what is a safe dose of epi for a cardiac patient
.04mg
how much solution is in a catridge of local anesthetic
1.8mL
what is in a cartridge of anesthetic
what is aspiration and why is it done
its pulling back the needles once inserted, looking for blood
its used to verify that the needle is not in a blood vessel or any vasculature
what happens if you inject into a blood vessel
it can travel to the heart and cause heart palpitations
what are the 3 branches of the trigemenial nerve
V1=opthalmic
V2=maxillary
V3 = mandibular
where does v1 exit
superior alveolar fissure
