Dermatitis from transcutaneous electric nerve stimulation

A patient is reported herein who developed allergic contact dermatitis to propylene glycol in a conductive jelly (Neuromod TENS gel) in an attempt to continue therapy, the patient changed to a poorly conductive surgical lubricant jelly which caused irritation and micropunctate burns.

Abstract

Transcutaneous electric nerve stimulation (TENS) is an effective treatment modality for chronic pain. Electrical impulses produced by a portable stimulator are transmitted by cable to electrodes which are attached to specific areas of the body by tape or adhesive. A conductive electrolyte jelly is utilized in order to make good electrical contact with the skin. Several dermatologic complications have been associated with the use of this technic, including allergic and irritant contact dermatitis and micropunctate burns caused by the improper use of poorly conductive lubricant jellies. A patient is reported herein who developed allergic contact dermatitis to propylene glycol in a conductive jelly (Neuromod TENS gel). In an attempt to continue therapy, the patient changed to a poorly conductive surgical lubricant jelly which caused irritation and micropunctate burns. Subsequently, electrodes not utilizing conductive jelly were applied, with excellent results.
