Flashcards in Anesthesia Part III Deck (44):
1

Maxillary Incisors are innervated by what nerve?

What type of injection would you do if you want to anesthetize the soft tissues?

Nasopalatine

Nasopalatine (don't need to go into Foramen)

2

If a pt gets an electric shock with IA, what has happened?

Needle has touched the nerve

3

What is a long acting LA w/out a vasoconstrictor?

Prilocaine

*mepivacaine is short acting

4

What nerve innervates the Maxillary PM's?

What injection for the Maxillary PM's?

MSA

MSA, AMSA, ASA (not PSA)

*the nerve is the MSA, the injection could be previous 3

5

What is the volume an anesthetic cartridge?

What is the volume of the anesthetic solution?

2.0 mL

1.8 mL

6

What injection are most concerned about having a Local Complication?

Why?

PSA

Venous Plexus

7

3 reactions to Intravenous Epi injection:

Fearful

Palpitations

Increased BP

8

Where should you inject if a pt has an infection?

Inject away from site

9

If the Mx 1st molar is infected, what type of injection should you do?

*what shouldn't do?

PSA (away from site)

*not infiltration

10

What 2 things are being anesthetized in an IA block?

What is anesthetized w/ Lingual and Long buccal?

Mandibular teeth on that side (central incisor to distal molar), soft tissue anterior to the molars

Tongue, buccal soft tissues of molars

11

What is the position of the thumb when giving an IA?

Coronoid notch, vestibule of soft tissue

12

What 4 nn. does the Gow Gates anesthetize?

Lingual

IA

Long Buccal (75%)

Mental

13

What injection is most likely to produce a positive aspiration?

Which is most likely to produce hematoma?

IA

PSA

14

What do you do with a positive aspiration?

Withdraw needle?

Change location

Yes if too much blood in cartridge and can't see

15

What is the challenge with Mandibular Infiltration?

What is the exception to this rule?

Dense Cortical Bone

Articaine (don't know why this workd)

16

Where is the Lingual n. in relation to the IA n.?

Anterior and Medial

*get as withdraw from IA block

17

What is the reason for giving a Long Buccal?

Buccal soft tissues of Molars

18

How much solution is administered for the IA (keeping in mind we have to give Long Buccal/Lingual on the way out)?

1.4 - 1.5 mL

3/4 cartridge

19

Where is the Long Buccal n.?

(2 data points)

External Oblique Ridge

Cusps of the Mandibular Molars

20

How far is penetration for the Long Buccal n.?

2-3 mm

*when touch bone

21

Where is the barrel of the syringe when administering an IA?

Contralateral PM's

22

What is the depth of penetration for a PSA?

16 mm

23

What is the depth of penetration for an IA?

If you contact bone too soon, you get no anesthesia and _____

20 - 25 mm

potentiate drug overdose

24

What is a major contributor to missing the IA by going too deep?

*proper technique is contacting bone, backing out ___mm, depositing

Hand moves forward

1 mm

25

What injection has the highest degree of failure?

IA

26

What is the opening of the needle (not the bevel)?

How is it measured?

Lumen

gauge

*large means small

27

How far above the Mandibular Occlusal Plane do we give the IA injection?

1.5 cm

15 mm

28

How long is the Long Needle?

How long is the Short Needle?

32 mm

29

What needle breaks?

30 gauge

(sometimes the 27)

30

Why are Blocks better than Infiltrations?

Less injections, Less drug delivered

31

What method of anesthetic delivery is prone to OD?

Infiltrations

*b/c give more

32

Working on a Maxillary 1st Molar with a PSA, pt reports sensitivity - what did we most likely miss?

What injection can we give?

MB root

ASA Nerve Block (which is different from ASA)


*MSA is another option, but won't be on test

33

2 most used Maxillary injections:

Infiltration

PSA

34

PSA gets Molars, buccal soft tissues, and supporting bone, but not...

Palatal Soft tissues/Bone

35

PSA gets the MB root of the Mx 1M __%

72%

36

ASA infiltration:

ASA Nerve Block:

Incisors - Canine

Infraorbital (Incisors - MB root Mx 1M)

37

AMSA location:

halfway between mid-palatal suture and FGM

between PM's

38

Greater Palatine NB location:

*Also V2

halfway between mid palatal suture and FGM

5 mm Anterior soft palate

39

Nasopalatal NB location:

What is unique about this injection?

P-ASA goes where?

PM level, lateral to Incisive Papilla

Only bilateral

Into Incisive Foramen

40

Long buccal Penetration site is distal to the 3rd Molar and contacts bone at ____ mm

2-3 mm

41

Gow Gates gets IA, lingual, auriculotemporal, mylohyoid, and log buccal nn. - it is inserted close to what?

toward head of condyle

42

Vazirani - Akinosi NB gets IA, Lingual, Long Buccal, and is done blind, and has what complication?

*going after V3 on lingual aspect of mandibular ramus

Trismus

43

Difference between Mental and Incisive NB?

Incisive palpated

44

PDL injections and Intraosseous anesthesia - won't use much

True
