The Effect of Microneedle Pretreatment on Topical Anesthesia

The Effect of Microneedle Pretreatment on Topical Anesthesia

This study evaluates the role of microneedle pretreatment in the speed at which anesthesia develops after application of topical 4% lidocaine.

This study evaluates whether the time to anesthesia with topical 4% lidocaine can be accelerated with the use of microneedle pretreatment. The study will evaluate the anesthesia as a randomized split-body study where each subject serves as their own control. The study will be performed on the volar forearm. Prior to application of the topical 4% lidocaine, one arm will be exposed to a microneedle pretreatment on a microneedle roller and the other arm will be exposed to sham microneedle treatment that will consist of a flat roller with no microneedles. Then pain will be assessed with the use of a spring loaded needle lancet that will be applied at 2 min, 5 min, 10 min, and 30 minutes after treatment.

Inclusion Criteria:

• Healthy volunteers

Exclusion Criteria:

• Allergy to lidocaine
