Comparison of Emla cream and topical lidocaine tape for pain relief of V-beam laser treatment

Abstract

The authors compared the analgesic effects of two topical applications; Emla^® cream (Sato Pharmaceutical Co. Ltd., Tokyo, Japan) and 60% lidocaine tape (Penles^® tape; Maruho, Osaka, Japan). The authors examined 20 outpatients with capillary malformations. Emla^® cream or Penles^® tape was applied 1 h before laser irradiation using V-Beam. After V-Beam irradiation, pain intensity was measured using Pain Vision^® (NIPRO, Osaka, Japan), while subjective pain was converted into numerical values using the VAS system. In the assessment using Pain Vision^®, pain was significantly lower in patients who received Emla^® cream (Welch test), whereas no difference was observed in VAS ratings between the two applications (student’s t test). The objective system showed that Emla^® cream had a significantly greater analgesic effect. We plan to evaluate the analgesic effects of these topical anesthetics by applying them to other anatomical areas.
