1. group?
2. indications
3. onset/duration

1. esters
2.
3. 7-8mins/ 1/2-3/4hrs

8

Cocaine (ester, BA) adverse effects.

System: excitement, convulsions, rapid palpitations, nausea, delirium
Ocular: desquamation, mydriasis, lid retraction (Muller's muscle; nonvoluntary)

9

Myelination enhances sensitivity dependent/independent of diameters.

independent of diameter

10

Small/large diameter highly active nerves tend to be more sensitivity.

small diameter nerve = more sensitive

11

Large diameters are less sensitive and thus recover quicker/slower than small.

Quicker = less sensitive

12

PABAs, MABAs, and BA are all esters/amides.

esters

13

Tetracaine, benzocaine, procaine and benoxinate are PABA/MABA/BA?

PABA; para amino benzoic acid

14

Proparacaine is PABA/MABA/BA?

MABA; mono amino benzoic acid

15

Cocain is PABA/MABA/BA?

BA; benzoic acid

16
