1 Wounds and Burns

2 Wounds A physical injury that somehow causes a break in the layers of the skin Two types: Open and Closed

3 Closed Wounds Skin’s surface is NOT broken
Damage occurs underneath the skin Examples: Bruising and Internal Bleeding

4 Bruises Medically called a contusion
Occurs when muscle fibers and connective tissue get crushed but the skin doesn’t break Blood leaks out of the ruptured capillaries, but has no where to go

5 Internal Bleeding Bleeding that occurs inside the body
Usually caused by traumatic injury, blood vessel rupture from high blood pressure, burst blood vessels, or certain diseases like Ebola Can compress organs until they stop functioning Can cause hemorrhagic shock, which can lead to death

6 Symptoms of Internal Bleeding
Tender, swollen, bruised, or hard areas of the body Especially in the abdomen Rapid, weak pulse Vomiting or coughing up blood Confusion, faintness, unconsciousness

7 Open Wounds Surface of skin is broken
Includes abrasions, lacerations, avulsions, punctures

8 Abrasion Wearing away of the upper layer of skin due to a friction force Usually a minor injury Examples: scrape, rug burn, road rash

9 Laceration Irregular and jagged wound caused when soft tissues tear
Treatment depends on deepness of the wound

10 Laceration from not wearing a helmet

11 Avulsion Torn sections of skin
Either a flap open on three sides or torn away completely Basically, ‘chunks’ of soft tissue or a body part is torn off completely

12 Puncture Caused when something pierces the skin and creates a small hole Usually don’t bleed very much Can get infected easily

13 Burns Special type of soft tissue injury
Can damage layers of skin, fat, muscle, and bones Caused by the sun, chemicals, boiling water, steam, fire, or electricity.

14 Three Degrees of Burns Treatment is based on classification
First is least severe, while third is most severe

15 First Degree Burns Also called Superficial Burns
Only the outer layer of the skin is burned Skin is red and a little swollen Doesn’t blister Takes about 3-6 days to heal

16 Second Degree Burns Also called Partial Thickness burns
Both the epidermis and dermis are burned Skin instantly gets red and splotchy Blisters usually form Considered minor if it’s less than 3 inches in diameter If it’s larger than that, or if it’s on the hands, feet, face, groin, butt, or over a joint, it’s considered a major injury

17 Third Degree Burns Also called Full Thickness burns
Involve all the layers of the skin Cause permanent damage Actually are painless because nerve ending have been burned Charred black, waxy, leathery, or dry and white Can also affect fat, muscle, and bone

19 Chemical Burns First, remove the chemical from the body
It will continue to burn as long as it is touching skin Flush with lots of cool running water for at least 20 minutes Don’t get the chemical on yourself and don’t get any more on the person Remember that chemicals can be inhaled!

20 Electrical Burns Can severely damage underlying tissue
Often causes a dark spot where the current entered First, make sure the person is not in contact with the power source Turn off the power at the source Electrocution can cause breathing emergencies

21 Burn Infections When people die from burns, they often actually die from infections

22 Treatment of Minor Burns
First degree and smaller second degree burns Hold the burn under cool running water for at least 5 minutes or until the pain subsides Better to not immerse the burn DO NOT put ice on the burn! This can cause frostbite Cover loosely with a sterile gauze bandage Make sure no pressure is put on the burn Take an over-the-counter pain reliever Advil, Tylenol, Ibuprofen, etc Don’t apply creams or butter Don’t break blisters

23 Treatment of Major Burns
Call 911 Don’t remove burnt clothing Don’t immerse in cold water This could cause shock Check for signs of circulation and breathing If no signs, do CPR Elevate the burned body areas, preferably above the heart Cover the area of the burn. Use a cool, moist (water), sterile bandage; clean, moist cloth; or moist towels
