In the use of 8% lidocaine pump spray as a lubricant on the Trachlight wand, its print mark was found to have dissolved. We therefore studied this dissolving effect on the print mark with three different types of lubricant (2% lidocaine jelly, 8% lidocaine pump spray and glycerin). ⋯ The manufacturer recommends that any topical anesthetics or other active ingredients should not be contained in a lubricant used on the Trachlight wand. We conclude that lidocaine pump spray should not be used as a lubricant on the Trachlight wand.
