Types of Open Wounds
An open wound is any soft tissue injury that breaks the skin. Open wounds can be minor or major.
There are many types of open wounds, including:
• Abrasions• Lacerations• Avulsions• Punctures

Types of Open Wounds
An abrasion is a scrape, such as carpet burn or road rash. Small abrasions are not usually serious, but can be painful.
The pain occurs because a scrape can expose many nerve endings.

Types of Open Wounds
A laceration is a cut, usually with a sharp object. Often the edges of the cut stay in their normal position, but sometimes they gape open.
Lacerations may be very small or they may be large. Lacerations can include skin, fat, muscle and other organs.

Types of Open Wounds
An avulsion is a tearing of the soft tissue. Amputation is a type of avulsion where the affected body part is completely torn away from the body.
Avulsions, especially amputations, are serious medical emergencies.

A puncture occurs when something pierces the skin. It may also penetrate other tissues. Sometimes the puncturing object remains in the wound.
Examples of puncture wounds include:
• Stepping on a nail• Sliver• Gunshot wound• Stab wound

Care for Minor Open Wounds
There are some general principles and application guidelines to remember when caring for minor wounds where no emergency condition exists.

3. General Principle: Promote Healing
Application: • Cover the wound with a clean
bandage• Change bandage daily• Talk to your healthcare provider
and get stitches or other wound closing treatment if needed
Open Wounds
Stitches?
Some minor wounds will heal better with stitches—a wound closing treatment. Knowing when a wound needs stitches can be tricky. If you are unsure, contact your healthcare provider.
However, here are some general guidelines to help you decide whether or not to seek medical care for your minor wounds.

Open Wounds
Stitches?
You should see a healthcare provider if:
• The edges of the cut do not stay together or gape open
• The wound is on the face and would form a noticeable scar
• The wound will not stop bleeding• The wound is larger than an inch• The wound is from a human or animal
bite• The wound has embedded objects,
such as gravel or glass• You can see the underlying fat,
muscle, or connective tissue• You cannot adequately clean the
wound
Open Wounds
Tetanus
Tetanus, or lockjaw, is a life-threatening disease caused by a bacteria found in soil. Tetanus occurs after a wound is infected with these bacteria.

Tetanus
There is a tetanus immunization that prevents the disease, but the immunization needs to be given every 7-10 years to maintain immunity or resistance to the bacteria.
For that reason, if you have a deep cut or a puncture wound, you may need to get a tetanus shot. Talk to a healthcare provider to determine if you need one.
Open Wounds
External Bleeding
Open wounds can cause external bleeding, or bleeding that you can see. It is important to know how to stop bleeding.

How to Stop Bleeding on Extremities
The general guidelines to stop bleeding on extremities:
• Apply direct pressure on the wound
• Use a clean dressing such as a gauze pad or a clean cloth. If a dressing isn’t available apply direct pressure without the dressing
• If the bleeding soaks through the dressing apply more dressings and use more pressure
Open Wounds
• Do not remove any dressing once they have been applied; doing so will break up the clots that the body is forming to stop the bleeding
• Once the bleeding has stopped, apply a bandage over the dressing

Open Wounds
• For non-extremity wounds it is suggested to use a hemostatic dressing which helps to clot and stop bleeding
• It is most effective when used properly with direct pressure on the wound
• You can get one of these dressings online or at a local store that carries first aid supplies

Open Wounds
Medical Emergency
If you are unable to stop the bleeding or if the person has lost a lot of blood, this is a medical emergency.

Open Wounds
Medical Emergency
Take the following actions:
1. Call 911 or the local emergency number.
2. Continue to attempt to stop the bleeding by applying firm pressure directly to the wound
3. Provide reassurance 4. Have the person rest
comfortably and cover them with a blanket to maintain body temperature
5. Monitor the person for signs of shock.
6. Treat shock if needed.
Open Wounds
Medical Emergency
Signs of shock include:
• Pale or bluish, cool, clammy skin
• Rapid, shallow breathing• Light-headed or dizzy• When you press on the skin, it
takes longer than three seconds for the color to return

Medical Emergency
Someone in shock can also have a change in their level of consciousness or level of alertness. They may also have an altered or mental status, including their intellectual or emotional functioning.
This may include confusion, agitation, or drowsiness.
Open Wounds
Medical Emergency
If emergency medical personnel are not available and you cannot stop the bleeding, you may need to apply a tourniquet. This is should only be done as a last resort!
You will learn more about tourniquets in the lesson on amputation.

Open Wounds
Disease Prevention
Blood borne pathogens—disease causing germs—are transmitted by coming in contact with another person’s blood or body fluids.
It is important to use personal protective equipment (PPE), such as disposable gloves when touching another person’s open wounds or blood.
Also be sure to wash hands thoroughly after contact with blood.
Open Wounds
Summary
You have learned about minor and severe open wounds. Remember that your first aid priorities are to stop bleeding, to prevent infection, and to promote healing.
Sometimes a wound needs to be evaluated by a medical professional even if it isn’t a medical emergency.
For wounds that are serious, call 911, attempt to stop the bleeding by direct pressure and a tourniquet if needed, and treat shock.
