The anesthetic patch with 30% lidocaine cream can be applied to the intact skin to produce complete skin anesthesia. It has been used for minor operations, intradermal allergen testing, lumbar punctures, bone marrow punctures, and venipunctures in a large series of patients during the past 11 years in both clinic and office practice. There have been no adverse reactions. Utilization of the anesthetic patch may promote more ready acceptance of painful medical diagnostic and therapeutic maneuvers, especially in children.
