Wound Care Signs and Symptoms

Scrapes and abrasions are superficial (on the surface). The deeper skin layers are intact, and bleeding is more of a slow ooze. They are usually caused by friction or rubbing against an abrasive surface.

Lacerations (cuts) go through all layers of the skin and into the fat or deeper tissues. Bleeding may be more brisk or severe. Severe blows by a blunt object, falls against a hard surface, or contact with a sharp object are the most common causes of lacerations.

Puncture wounds are generally caused by a sharp pointed object entering the skin. Most common examples are stepping on a nail, getting stuck with a needle or a tack, or being stabbed with a knife. Bleeding is usually minimal, and the wound may be barely noticeable.

Human bites and animal bites can be puncture wounds, lacerations, or a combination of both. These wounds are always contaminated by saliva and require extra care.
