What is the dosage of lidocaine in a 2% 1.7 cc cartridge?

To determine the dosage of lidocaine in a 2% solution contained in a 1.7 cc cartridge, we need to understand how to calculate the amount of lidocaine based on the concentration and volume.

A 2% lidocaine solution means that there are 2 grams of lidocaine per 100 milliliters (ml) of solution. To convert this into milligrams:

• 2 grams is equivalent to 2000 milligrams.

• Therefore, in 100 ml of solution, there are 2000 mg of lidocaine.

Now, if we have a 1.7 cc cartridge, we first convert cc to ml (1 cc equals 1 ml). Therefore, 1.7 cc is the same as 1.7 ml.

Next, we calculate the amount of lidocaine present in 1.7 ml of the 2% solution. We can set up the calculation as follows:

• The amount of lidocaine in 1 ml is the total mg in 100 ml divided by 100. This gives us 2000 mg / 100 ml = 20 mg/ml.
• Now, we multiply the concentration (20 mg/ml) by the volume (1.7 ml):
