Quick Answer
Signs of necrosis in wilderness wounds can be identified by a decrease in wound size, but an increase in wound depth, as well as the presence of a black or eschar-covered area. These signs may also be accompanied by a foul odor, increased pain, or swelling around the wound. In severe cases, the wound may exhibit a grayish or pale appearance.
Identifying Necrotic Tissue
To identify necrotic tissue, look for a change in wound color from red or pink to grayish or pale. This can be a sign that the tissue is dying and will eventually slough off. Another indicator is a decrease in wound size, but an increase in wound depth, which can lead to a tunneling effect. It’s essential to examine the wound regularly to catch signs of necrosis early.
Removing Necrotic Tissue
Necrotic tissue can be removed by debridement, a process that involves gently scraping off the dead tissue with a sterile scalpel or forceps. This should be done in a sterile environment to prevent infection. The debridement should be done at a 45-degree angle to avoid pushing the necrotic tissue further into the wound, which can create a tunnel. A minimum of 1/4 inch of healthy tissue should be left around the wound edges to promote healing.
Preventing Necrosis
Preventing necrosis in wilderness wounds involves keeping the wound clean and dry, applying a topical antibiotic ointment, and covering the wound with a non-stick dressing. It’s also essential to change the dressing regularly to prevent bacterial growth. In severe cases, medical attention may be required to prevent further tissue damage and promote healing.
