Interesting and Consistent Results Utilizing a Microporous Pigmented Antibacterial Polyvinyl Alcohol (PVA) Foam to Augment Wound Bed Preparation

Abstract

Chronic open wounds, particularly venous leg ulcers, frequently accumulate a stubborn gelatinous material that is not easily removed with routine cleansing, without significant force being applied to the wound bed. The force required to remove it is often painful for the patient. Often described as slough, this leads one to think of it as necrotic tissue, yet in an uninfected, well perfused ulcer, continuous necrosis does not make sense. This coagulum, however, often requires removal by a sharp instrument due to its tenacious attachment, and is often not impacted by topically applied collagenase, presumably because of the absence of devitalized collagen.
