Signs and Symptoms of Closed Wounds

            The area may appear red or purple, and there may be swelling. The bruised area is often painful.


            First Aid Care for Closed Wounds

            Applying a cold pack to the bruised area can
            help to decrease the bleeding and reduce pain
            and swelling. To make a cold pack, fill a sealable
            plastic bag with a mixture of ice and water. Before
            applying the cold pack to the person’s skin, wrap
            it in a thin, dry towel to protect the skin from injury.
            Hold the cold pack in place for no more than 20
            minutes, and then wait at least 20 minutes before
            applying the cold pack again. If the person is not
            able to tolerate a 20-minute application, apply
            the cold pack for periods of 10 minutes on and
            off. Elevating the injured area may help to reduce
            swelling, but do not elevate the injured area if
            doing so causes pain.

            Open Wounds


            In an open wound, the skin’s surface is broken and blood may come through the tear in the skin, resulting in
            external bleeding (bleeding that is visible on the outside of the body).


            Types of Open Wounds

            The four main types of open wounds are abrasions, lacerations, avulsions and puncture wounds (Figure 6-1).

            ■    An abrasion occurs when something rubs         vessels and tendons. If nerves are damaged, the
                roughly against the skin, causing damage to the   laceration may not be painful. Bleeding may be

                know how painful these injuries can be! This is   and sometimes the underlying tissue, is partially
                because scraping of the outer skin layers exposes   or completely torn away. Avulsions are commonly
                sensitive nerve endings. Abrasions are shallow   caused by animal bites. Elderly people are also
                wounds that do not bleed much. However,         susceptible to avulsion wounds as a result of a
                because of the mechanism of injury (usually a   fall or other trauma because their skin is fragile
                sliding fall), abrasions are often contaminated   and tears easily. Avulsion wounds often cause
                with dirt and debris. To remove the dirt and    significant bleeding.
                debris, rinse the abrasion thoroughly with running
                water, and then wash the area with soap and   ■    A puncture wound occurs when a pointed
