Soft tissue injuries

Soft Tissue Injuries

Treatment Procedures


Skin anatomy and physiology

Skin Anatomy and Physiology

  • Body’s largest organ

  • Three layers

    • Epidermis

    • Dermis

    • Subcutaneous tissue


Skin anatomy and physiology1

Skin Anatomy and Physiology

  • Complex system, variety of functions

    • Sensation

    • Control of water loss

    • Protection against microbes

    • Temperature control


Soft tissue injuries1

Soft Tissue Injuries

  • Closed

  • Open


Closed injury

Closed Injury

  • Associated with blunt trauma

  • Skin remains intact

  • Damage occurs below surface

  • Types

    • Contusions

    • Hematomas


Contusion

Contusion

  • Produced when blunt force damages dermal structures

  • Blood, fluid leak into damage area causing swelling, pain

  • Presence of blood causes skin discoloration called ecchymosis (bruise)


Hematoma

Hematoma

  • “Blood lump”

  • Larger blood vessel damaged

  • Causes mass of blood to collect in the injured area

  • Fist-sized hematoma = 10% volume loss


With closed soft tissue injury

With Closed Soft Tissue Injury

  • How much blood is tied up in that injury rather than circulating in the vessels?

  • What could the force the caused the soft tissue trauma have done to underlying organs?


Closed injury management

Closed Injury Management

  • Rest

  • Ice

  • Compression

  • Elevate

  • Splint

When in doubt assume underlying fractures are present


Open injury

Open Injury

  • Skin broken

  • Protective function lost

  • External bleeding, infection become problems


Open injury types

Open Injury Types

  • Abrasions

  • Lacerations

  • Punctures

  • Avulsions

  • Amputations


Abrasion

Abrasion

  • Loss of portions of epidermis, upper dermis by rubbing or scraping force.

  • Usually associated with capillary oozing, leaking of fluid

  • “Road rash”


Laceration

Laceration

  • Cut by sharp object

  • Typically longer than it is deep

  • May be associated with severe blood loss, damage to underlying tissues

  • Types

    • Linear

    • Stellate


Punctures

Punctures

  • Result from stabbing force

  • Wound is deeper than it is long

  • Difficult to assess injury extent

  • Object producing puncture may remain impaled in wound


Avulsions

Avulsions

  • Piece of skin torn loose as a flap or completely torn from body

  • Result from accidents with machinery and motor vehicles

  • Replace flap into normal position before bandaging

  • Treat completely avulsed tissue like amputated part


Amputations

Amputations

  • Disruption of continuity of extremity or other body part

  • Part should be wrapped in sterile gauze, placed in plastic bag, transported on top of cold pack

  • Do NOT pack part directly in ice

  • Do NOT let part freeze


Open wound management

Open Wound Management

  • Manage ABCs first

  • Control bleeding

  • Prevent further contamination, but do not worry about trying to clean wound

  • Immobilize injured part

  • Mange hypoperfusion if present


Special considerations

Special Considerations

  • Impaled objects

  • Eviscerations

  • Open chest wounds

  • Neck wounds

  • Gunshot wounds


Impaled objects

Impaled Objects

  • Do NOT remove

  • Stabilize in place

  • Exception

    • Object in cheek

    • Remove, dress inside and outside mouth


Eviscerations

Eviscerations

  • Internal organs exposed through wound

  • Cover organs with large moistened dressing, then with aluminum foil or dry multi-trauma dressing

  • Do NOT use individual 4 x 4’s

  • Do NOT attempt to replace organs


Open chest wound

Open Chest Wound

  • May prevent adequate ventilation

  • Cover with occlusive dressing

  • Monitor patient for signs of air becoming trapped under pressure in chest (tension pneumothorax)

  • If tension pneumo develops lift dressing corner to relieve pressure


Neck wounds

Neck Wounds

  • Risk of severe bleeding from large vessels

  • Risk of air entering vein and moving through heart to lungs

  • Cover with occlusive dressing

  • Do NOT occlude airway or blood flow to brain

  • Suspect presence of spinal injury


Gunshot wound

Gunshot Wound

  • Special type of puncture wound

  • Transmitted energy can cause injury remote from bullet track

  • Bullets change direction, tumble

  • Impossible to assess severity in field or ER

  • Patient must go to OR
