简要总结

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

详细描述

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.

研究组 & 干预措施

Microneedle Pretreatment

Active Comparator

One ventral forearm is randomized to receive pretreatment with microneedle rollers that are 200 micrometers in length (Clinical Resolution Laboratories, Inc.). Then topical 4% lidocaine is applied and pain in assessed after a pain stimulus at the 2 min, 4 min, 10 min, and 30 min time points.

干预措施: Microneedle Roller (Device)

Sham Microneedle Pretreatment

Sham Comparator

One ventral forearm is randomized to receive pretreatment with sham microneedle rollers (flat roller without any microneedles) that are 200 micrometers in length (Clinical Resolution Laboratories, Inc.). Then topical 4% lidocaine is applied and pain in assessed after a pain stimulus at the 2 min, 4 min, 10 min, and 30 min time points.

干预措施: Sham microneedle Roller (Device)

结局指标

主要结局

Visual Analog Scale Pain

时间窗: 30 min

100 mm Visual Analog Scale pain grading. Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity.
