Q

Infant needs extractions of D,E,F,G and weights 22 pounds. Calculate the lidocaine and septocaine dosage

A

Lidocaine = 2mg/lb
Max dose = 2x22 = 44mg
Carouse contains 34mg
Thus, safe to use 1.3 carpules

Septocaine = 3.2mg/lb
Max dose = 3.2x22 = 70.4mg
Carpules contain 68mg
Thus, safe to use 1 carpule

A

2-3mm in surface tissue depth

18
Q

When is compounded topical anesthetics used?

A

Orthodontic treatment and pediatric dentistry to anesthetize palatial tissues prior to injection and for extraction of loose primary teeth

19
Q

True or false: allergy to one amide-type anesthetic means that you are allergic to all amide-type anesthetics

A

False - allergy to one does not mean allergy to all.

20
Q

True or false: allergy to one ester-type anesthetic means allergy to all

A

True

21
Q

What does an allergy to bisulfate mean in terms of using local anesthesia?

A

There is a risk of inducing methemoglobinemia

23
Q

True or false: allergy to local anesthesia is due to dosage

A

False - it is due to the patient’s capacity to react to even a small dose

24
Q

Which local anesthetics have the highest risk of parenthesia?

A

Articaine and prilocaine

25
Q

Can you use local anesthetics with sedatives?

A

No because they both depress the CNS

26
Q

Can you use local anesthetics with opioids? With narcotics?

A

No because toxicity increases with opioids

Narcotics + local may decrease protein binding and elevate CO2, thus, increase CNS sensitivity to convulsions

27
Q

When do we need local anesthesia? (4)

A
  1. Extraction of a tooth
  2. Accessing a vital pulp
