How much local anesthetic is in two cartridges of 1% lidocaine?

To determine the amount of local anesthetic in two cartridges of 1% lidocaine, it's essential to understand the concentration and volume of the anesthetic solution contained in each cartridge.

A 1% solution of lidocaine means that there are 1 gram of lidocaine in 100 mL of solution. Since each cartridge typically holds 1.8 mL of the anesthetic solution, we can calculate the amount of lidocaine in one cartridge as follows:

1% solution = 1 gram per 100 mL = 1000 mg per 100 mL.

To find out how much is in 1.8 mL:

• First, determine the amount of lidocaine in 1 mL:

1000 mg / 100 mL = 10 mg/mL

• Then, calculate the amount in 1.8 mL:

10 mg/mL × 1.8 mL = 18 mg

Now, since there are two cartridges, you multiply the amount of lidocaine in one cartridge by two:

18 mg × 2 = 36 mg.

It looks like there was a miscalculation in determining the result presented as the correct answer. Two cartridges of 1%
