Abstract
Abstract Medication, in the form of an anaesthetic gel, is applied to the incision resulting from an episiotomy by providing a gelretaining zone in a sanitary napkin. The medication is provided on an impermeable layer affixed to the absorbing face of the napkin and is protected from contamination, prior to use, by a covering membrane. The impermeable layer between the anaesthetic gel and the napkin prevent the absorption of the former on the latter. The gel-retaining zone is approximately two inches by three inches in size and is spaced by about one inch from the forward edge of the absorbent region of the sanitary napkin.
