Q

what is the first step of calculating MRD of local anesthetics

A

determine amount of local anesthetic in 1 carpule as mg / carpule

1 - change % of local anesthetic to mg/ml
2 - multiply mg/ml by 1.8 ml/carpule

Q

how many milligrams of articaine are in a carpule of 4% articaine with 1:100,000 epi? Septodont, the manufacturer of Septocaine (articaine), manufactures this in 1.7 ml carpules?

a - 72 mg
b - 68 mg
c - 36 mg

A

b - 68 mg

steps:
- 4% x 10
- 40 mg/ml x 1.7

17
Q

what is the third step of calculating MRD of local anesthetics

A

determine maximum number carpules for patinet’s weight

max dose / (mg / carpule)

18
Q

Imagine you’ve been chosen to give the Tiger King a smile makeover (lucky you!). He weighs 170 lbs. How many carpules of 2% lidocaine with 1:100,000 epi can you give him? He has an unremarkable health histroy.

a - 15.1 carpules
b - 11.1 carpules
c - 10 carpules
d - carole baskin says give him 20!

A

b - 11.1 carpules

170 lb x 3.2 mg/lb = 544 mg
MRD = 500 mg so use 500
500 mg / (36 mg/carpule) = 13.8 carpules

BUT

MRD for epi is 0.2 mg
0.2 mg / 0.018 mg = 11.1 carpules

EPI = rate limiting

19
Q

how do you calculate the amount of local anesthetic administered

A

(# of carpules used) x ( mg of anesthetic / carpule)

20
Q

what are the steps for switching to a different local anesthetic when reinjecting

A

1 - calculate MRD of 2nd local anesthetic
2 - compare MRD of 2nd to 1st & use the LOWEST MRD
3 - subtract dose administered from lowest MRD
4 - calculate # of carpules for patient’s weight using remaining maximum dose

21
Q

So if a 110 lb patient has received 2 carpules of 2% lidocaine. The stock room is out of lidocaine. How many carpules of 4% prilocaine can you now administer?

A

110 x 3.2 =352
110 x 4.0 = 440
so use 352 because smaller dose
352 - 72 (the two carpules used already) =280
280 is the remaining max dose
280 / 72 (1 carpule of 4% prilocaine) = 3.8 carpules of prilocaine can be given

originally patient could have been given 9 carpules of lidocaine but with adjustments now patient can only receive 5.8 carpules (2 lidocaine & 3.8 prilocaine)

22
Q

During your smile makeover of the Tiger King, you give him 3 carpules of 2% lidocaine with 1:100.000 epi on the mandible, but you decided to use 4% articaine with 1:100,000 epi on the maxilla. How many carpules of articaine can you give him? recall he weighs 170 lbs.

a - 4.8 carpules
b - 5.7 carpules
c - 6.4 carpules
d - 5.3 carpules

A

b - 5.7 carpules

20 x 1.8 x 3 = 108 lidocaine used
170 x 3.2 = 544
170 x 3.2 = 544
use 500 bc AMD for lidocaine is 500 which is smaller than the MRDs
500 - 108 = 392 remaining max dose
392 / 68 (1 carpule of 4% articaine that comes in 1.7 ml) = 5.7 carpules of articaine can be given

23
Q

what is the MRD of epinephrine in a healthy pateint

A

0.2 mg

24
Q

what is the MRD of levonordefrin in a healthy patient

A

1.0 mg

25
Q

what is the cardiac dose of epinephrine

A

0.04 mg

26
Q

what is the cardiac dose of levonordefrin

A

0.2 mg

27
Q

what are the steps for calculating MRD for vasoconstrictors

A

1 - calculate mg of vasoconstrictor in 1 carpule
2 - determine MRD - healthy dose or cardiac dose
3 - convert MRD to max number of carpules

28
Q

how many mg/ml is 1:100,000 epi

A

0.01 mg/ml

29
Q

what is the drug that limits the number of local anesthetic carpules administered based upon the patient’s medical status

A

limiting drug

30
Q

what is usually the limiting drug in healthy patients

A

local anesthetic agent

31
Q

what is usually the limiting drug in cardiac patientis

A

vasoconstrictor
