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).
