What's Better for Wounds: Scabs or Bandages?

When you cut your skin, your body knows exactly what to do in order to heal the pesky wound as fast as possible. Eventually, a brownish rust colored scab forms over the cut. But what is a scab made of, and why do they just fall off? In less than 10 seconds after a cut occurs, the body does two things: It uses sticky blood cells called platelets to prevent an extended amount of blood loss from the wound, and deploys white blood cells to attack any outside substances—such as bacteria—that may have snuck in before the clot was fully formed. To hold the clot in place, a thread-like protein called fibrin begins to form a structure throughout the clot.

Tissue damage in humans triggers a well-characterized response marked by rapid blood clotting and a recruitment of epidermal cells to the injury. When you remove a scab, you're also removing some of the newly regenerated tissues growing underneath, thereby interfering with the healing process. Many different cell types and proteins have been linked to the repair process, but the complexity of the mammalian wound response has challenged efforts to determine their individual roles. Only the first step—the signaling cascade that promotes blood clotting—is understood at the molecular level. Since dissecting the wound response pathway at the molecular level requires an organism that lends itself to relatively easy genetic manipulations, Michael Galko and Mark Krasnow of Stanford University turned to the quintessential genetics organism, Drosophila melanogaster , to create a novel system for studying wound healing.

Knowing the difference between a scab and eschar may not seem like a big deal. However, if you are being audited, or your facility is in survey, you might think otherwise. Here are a couple of scenarios for you to think about. You have an acquired, unstageable pressure ulcer in a long-term care facility. First, an sDTI is intact skin with no depth. The tissue level of destruction may be full-thickness, but intact skin.

The Molecular Biology of Wound Healing

Scabs are a defense against debris, infection, and blood loss., When you suffer a cut, abrasion, or bleeding wound in the skin, a scab forms to stop the bleeding and cover the cut with a protective layer.

    If you look at a scab, it probably just looks like a hard, reddish glob. But under its surface, all kinds of things are going on. New skin cells are being made to help.
