How is the number of lidocaine injections per arm determined in a miraDry procedure?

The amount of numbing lidocaine injected for a miraDry procedure depends on the size of the person.  Bigger people have bigger armpits and need more volume of the numbing solution. The new technique uses smaller needles so less discomfort and less bruising.  Keep in mind that the numbing solution is very dilute so the risk of too much medication is very low.  Swelling after miraDry is very common more because of the treatment, not the numbing.

The injection techniques can vary between offices. We use the High Volume Anesthesia technique which is also called Tumescent Anesthesia. The very dilute anesthesia is injected with very little discomfort and typically it is only the first couple of injections that you feel. With this technique, you have the highest level of protection for the nerves that go through the underarm area to the fingers and because of this technique's safety, we are able to treat everyone with the highest level of energy and better results.Dr. Quenby Erickson, DO, FAAD
