1 Chapter 10 Soft Tissue Injures Brittney Morgan & Katie Larson

2 Vocabulary  Soft tissues - Body structures that include the layers of skin, fat, and muscles.  Wound - An injury to the soft tissue.  Burn - An injury to the skin or to other body tissues caused by heat, chemicals, electricity or radiation.  Dressing - A pad placed directly over a wound to absorb blood and other body fluids and to prevent infection.

3 Soft Tissues  The soft tissues include the layers of skin, fat, and muscle that protect the underlying body structures.  Epidermis – Provides a barrier to bacteria and other organisms that can cause infection.  Dermis – Contains the nerves, sweat glands, oil glands, and blood vessels.  Hypodermis – Contains fat, blood vessels and connective tissues.  Adipose – Insulates the body to help maintain body temperature, mechanical cushion, and source of energy.

4 Wounds  Closed wound – Skin’s surface is not broken; tissue damage and any bleeding occur below the surface  Contusion – The simplest closed wound, also called a bruise. When a bump or blow occurs, it results in damage to soft tissue layers and vessels, causing internal bleeding. Blood and other fluids seep into surrounding tissues, causing discoloration and swelling.

5 Closed Wounds  Contusion – The simplest closed wound, also called a bruise. When a bump or blow occurs, it results in damage to soft tissue layers and vessels, causing internal bleeding. Blood and other fluids seep into surrounding tissues, causing discoloration and swelling.

6 Signals of Severe Internal Bleeding:  Rapid breathing  Excessive thirst  An injured extremity that is blue or extremely pale

7 Open Wounds  Open wounds - Skin’s surface is broken and blood may come through

8 Open Wounds  Abrasion – Skin that has been rubbed or scraped away.  Laceration – A cut, which may have either jagged or smooth edges.  Avulsion – A portion of the skin and sometimes other soft tissue is partially or completely torn away.  Amputation – A body part that is severed.  Puncture/Penetration – when the skin is pierced with a pointed object.

9 General Care  Minor Wounds  Major Wounds  Embedded/Impaled Objects

10 Minor Wounds  Use a barrier between you and the victim  Apply direct pressure for a few minutes to control bleeding  Wash the wound thoroughly with soap and water and gently dry with clean gauze  Cover with clean dressing and a bandage  Wash hands immediately after

11 Major Wounds  Call 911 or emergency local number  Put on gloves  Control external bleeding by: o Cover with dressing and press firmly o Apply pressure bandage o If blood soaks through, do not remove the original bandage, add more

12 Major Wounds(page 2)  Monitor persons condition  Have person rest comfortably  Wash your hands

13 Embedded/Impaled Objects  Call 911  Put on disposable gloves  Do not remove object  Apply direct pressure to edges of the wound  Use a bulky dressing to stabilize the object  Control bleeding by bandaging the dressing in place around the object  Wash hands immediately after

14 Infection  Care: o Keep area clean o Soak in clean, warm water o Apply antibiotic ointment

15 Burns  1 st Degree  2 nd Degree  3 rd Degree  Care for burns  Chemical  Electrical

16 1 st Degree Also called a superficial burn.  Involve only the top layer of skin  Cause skin to become red and dry; are usually painful; and the area may swell  Usually heal within a week

17 2 nd Degree Also called a partial-thickness burn.  Involve the top layers of skin  Cause skin to become red; are usually painful; have blisters that may open and weep clear fluid  Usually heal in 3 to 4 weeks

18 3 rd Degree Also called a full-thickness burn.  May destroy all layers of skin and some or all of the underlying structures.  The skin may be brown or black (charred), with the tissue underneath, can either be extremely painful or painless (If the burn destroys nerve endings).  Healing requires medical assistance; scarring is likely.

19 Care For Burns Heat (Thermal)  Stop the burning by removing the person from the source of the burn  Check for life-threatening conditions  Cool the burn with large amounts of cold running water  Cover loosely with a sterile dressing  Take steps to minimize shock  Comfort and reassure the person

20 Care For Burns Chemical  Remove the chemical from the skin, be careful not to get the chemical on yourself  Flush the burn with large amounts of cool running water. Continue for 20 minutes.  Take steps to minimize shock

21 Care For Burns Electrical  Check the scene  If possible, turn off the power at its source and care for any life threatening emergencies  Call 911  Care for shock and thermal burns  Look for entry and exit wounds  Check for additional injuries
