Chapter 19: Soft-Tissue Injuries

Anatomy of the Skin

Function of the Skin

• Protection

• Sensation

• Temperature control

Soft-Tissue Injuries• Closed injuries

– Soft-tissue damage beneath the skin

• Open injuries– Break in the surface of the skin

• Burns– Soft tissue receives more energy

than it can absorb

Contusion

• Results from blunt force striking the body

Hematoma

• Pool of blood that has collected in the body

Crushing Injury

• Occurs when a great amount of force is applied to the body for a long period of time

• Rest the patient and injured part.• Ice slows bleeding.• Compression over an injury slows

bleeding.• Elevation above the level of the

heart reduces swelling.• Splinting decreases bleeding and

reduces pain.

Abrasions• Caused by friction

Laceration• Smooth or jagged cut

Avulsion

• Separation of various layers of the skin

Penetrating Wound

• Results from a sharp pointed object

Gunshot Wounds

• Gunshot wounds have unique characteristics.

Crushing Open Wound

• May involve damaged internal organs or broken bones

Emergency Medical Care (1 of 2)

• Use proper BSI precautions.

• Administer oxygen if needed.

• Your treatment priority is ABCs—including controlling the bleeding.

• Apply a dry, sterile dressing over entire wound.

• Apply pressure over the wound with your gloved hand.

Emergency Medical Care (2 of 2)

• Maintain pressure and secure dressing with a roller bandage.

• Elevation can help control bleeding.• Leave original dressing in place if bleeding

continues.• Apply a second dressing on top of first and

secure.• Applying pressure to an arterial pressure

point can help as well.• Splint the extremity.

Chest Wounds

• A penetrating wound to the chest may cause air to enter the chest.

Chest Wound Management

• Keep the patient supine and administer oxygen.

• Seal the wound.

• Per local protocol, you might only secure three sides of the dressing. This can create a one-way valve.

Abdominal Wounds

• An open wound in the abdomen may expose organs.

• An organ protruding through the abdomen is called an evisceration.

Abdominal Wound Management

• Do not touch exposed organs.

• Cover organs with a moist sterile dressing.

• Arrange for immediate transport.

Impaled Objects

• Do not attempt to move or remove the object.

• Control bleeding and stabilize object.

• Evacuate to aid room carefully.

Amputations• Immobilize a partial amputation with bulky

dressings and a splint.

• Wrap a complete amputation in a dry, sterile dressing and place in a plastic bag.

• Put the bag in a cool container filled with ice. Protect from freezing.

• Transport severed part with patient.

Neck Injuries

• An open neck injury can be life threatening.• Air can get into the veins and cause an air

embolism.• Cover the wound with an occlusive dressing.• Apply manual pressure.• Secure a pressure dressing loosely over the

neck and firmly through the opposite axilla.

• Burns account for more than 6,000 deaths/year.

• Burns are one of the most serious and painful injuries.

• Remember to perform a complete assessment on burn patients for other injuries.

Determining Burn Severity

• What is the depth of the burn?

• What is the extent of the burn?

• Are any critical areas involved?

• Are there any preexisting medical conditions or other injuries?

• Is the patient younger than 5 years or older than 55 years of age?

Depth of Burns (1 of 3)

• Superficial (first-degree) burns

• Involve only top skin layer

• Partial-thickness (second-degree) burns

• Involve the epidermis and some portion of the dermis

• Full-thickness (third-degree) burns

• Extend through all layers of the skin

Extent of Burns

Pediatric Needs

• Burns to children are considered more serious than burns to adults.

• Children have more surface area relative to body mass than adults.

• Many burns result from abuse.

• Report all suspect cases of abuse to the authorities.

Emergency Care for Burns (1 of 2)

• Follow proper BSI precautions.

• Move the patient away from the burning area.

• Immerse the affected area in cool, sterile water or saline solution and cover with a cool, wet dressing.

• Give oxygen if the patient has a critical burn.

Emergency Care for Burns (2 of 2)

• Prevent body heat loss.

• Rapidly estimate the burn’s severity.

• Check for traumatic injuries.

• Treat the patient for shock.

• Arrange for prompt transport.

Chemical Burns

• Occur whenever a toxic substance contacts the body

• Eyes are particularly vulnerable.

• Fumes can cause burns.

• To prevent exposure, wear appropriate gloves and eye protection.

Care for Chemical Burns• Remove the chemical from the

patient.• If it is a powder chemical, brush off

first.• Remove all contaminated clothing.• Flush burned area with large amounts

of water for about 15 to 20 minutes.• Arrange for prompt transport.

Electrical Burns

• Make sure the power is off before touching the patient.

• There will be two wounds (an entrance and an exit wound) to bandage.

• Arrange for prompt transport and be prepared to administer CPR.

Functions of Dressing and Bandaging

• Control bleeding

• Protect the wound

• Prevent contamination

Dressings and Bandages

• Sterile dressings

– Used to cover wounds

• Bandaging

– Used to keep dressing in place
