Wet-to-Dry Dressings-Evaluating the Evidence.

Wound Care Management
Abstract:
In 2008, the use of wet-to-dry dressings for wound care surprisingly remains the mainstay for many practitioners and is considered a traditional dressing. But does traditional practice have a place in wound care today? With the ever-increasing emphasis on evidence-based practice, this article evaluates the evidence of wet-to-dry dressings and its relation to moist wound healing, which is considered the standard of care. A brief history of wound care will also be discussed.
