A traditional method for wound care involves the application of a moistened gauze dressing to a wound bed. This dressing is then allowed to dry. Subsequent removal of the now-dry material mechanically debrides the wound, removing necrotic tissue and exudate that have adhered to the gauze fibers during the drying process. The materials used typically include sterile saline or another prescribed solution to moisten the gauze.
This technique, once widely implemented, was intended to facilitate wound cleansing and promote granulation tissue formation. The mechanical debridement offered a simple and readily available approach to managing wounds. However, it’s crucial to note that this method is non-selective; in addition to removing undesirable tissue, it can also disrupt healthy tissue and impede the healing process, potentially causing pain and trauma during removal. Furthermore, as the dressing dries, it can become firmly attached to the wound bed, leading to increased discomfort and potential bleeding upon removal.
