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

Scene Size-up

• Observe for hazards. • Take BSI precautions.• Place several pairs of

gloves in pocket.• You may be able to

identify bleeding before even reaching patient.

• Look for indicators of MOI.

Initial Assessment (1 of 2)

• Observe patient for seriousness of condition.• Does patient have any apparent life threats?• Look for hidden injuries.• Ensure patent airway.• Protect patient from further spinal injury.• Quickly assess breathing.• Palpate chest wall for DCAP-BTLS.

Initial Assessment (2 of 2)

• If soft-tissue injury is discovered on chest or abdomen:– Check for clear and symmetrical breath sounds.– Provide high-flow oxygen or assisted

ventilations. • Quickly assess pulse rate and quality.• Closed soft-tissue injuries do not have visible signs

of bleeding.• Pulse will indicate how aggressively you need to

treat for shock.

Transport Decision

• If patient has signs of shock or airway or breathing problem, consider quickly transporting or requesting ALS.

• Do not delay transport of closed-injury patient who may have more serious deeper injury.

Focused History and Physical Exam

• Patients with significant MOI may need a rapid physical exam to identify injuries.

• Focused physical exam– Focus assessment on the isolated closed injury,

complaint, and affected body region.• Rapid physical exam

– Perform if significant trauma has likely affected multiple systems.

– Make sure cervical collar is applied.

Baseline Vital Signs

• Closed-injury patients may rapidly become unstable.

• Look for tachycardia; tachypnea; low blood pressure; weak pulse; and cool, moist skin.

• Soft-tissue injuries, even without a significant MOI, can cause shock.

SAMPLE History

• Obtain from responsive patient or bystanders/family.

• Look for medical ID jewelry or cards.

Interventions

• Provide complete spinal immobilization early if spinal injuries are suspected.

• Provide high-flow oxygen.• Treat aggressively for shock.• Request ALS if necessary.• Do not delay transport.

Detailed Physical Exam

• Any time there is a significant MOI, perform detailed physical exam if time permits.

Ongoing Assessment

• Repeat the initial assessment.• Reassess vital signs frequently.• Communication and documentation

– Provide accurate account of how you treated injuries.

RICES

• Rest—keep patient quiet and comfortable as possible.

• 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

• 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

Scene Size-up

• Wear BSI.• Do not touch equipment with bloody gloves; wear

several pairs.• Beware of contaminating one patient with another

patient’s blood.• Wear eye protection.• Consider MOI.

Initial Assessment

• There may be internal underlying injuries.• Injuries can affect airway and breathing.• Provide spinal immobilization.• If the patient has an open chest wound, evaluate

for bubbling or sucking sounds.• Quickly place an occlusive dressing over wound. • Provide high-flow oxygen.• Assess pulse and skin for shock.• Control significant bleeding.

Transport Decision

• Consider quick transport if patient has airway or breathing problem or significant bleeding.

• Stay focused on problems at hand.• Patients with significant bleeding or internal

bleeding may quickly become unstable.• Watch for signs of shock.

Focused History and Physical Exam

• Focused physical exam– Perform in responsive patient with simple open

injury.– Focus on isolated injury, complaint, and affected

body region.• Rapid physical exam

– Perform if there is significant trauma likely affecting multiple systems.

– Look for DCAP-BTLS.– Do not delay transport.– Be sure that spine is stabilized.

Baseline Vital Signs/SAMPLE History

• Baseline vital signs– Will help determine if patient is going into shock

• SAMPLE history– Anemia and hemophilia– Medications that thin the blood (aspirin,

prescribed blood thinners)

Interventions

• Control bleeding.• If bleeding is not

significant, control later in assessment.

• Stabilize spine and assist breathing.

• Splint painful, swollen, deformed extremities.

Detailed Physical Exam

• Perform if patient is stable and time allows.

Ongoing Assessment

• Assess all bandaging frequently.• Reassess ABCs often.• Communication and documentation

– Include description of MOI and patient’s position.

– Estimate and report amount of blood loss.– Describe location, size, depth of injury.

Emergency Medical Care (1 of 3)

• Use proper BSI precautions.

• Administer oxygen if needed.

• Treatment priority is ABCs—including controlling bleeding.

Emergency Medical Care (2 of 3)

• Apply dry, sterile dressing over entire wound.

• Maintain pressure and secure dressing with a roller bandage.

Emergency Medical Care (3 of 3)

• Leave original dressing in place if bleeding continues.

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

• Splint the extremity.

Abdominal Wounds

• Open wound in abdomen may expose organs.

• Organ protruding through abdomen is called an evisceration.

Abdominal Wound Management

• Do not touch exposed organs.

• Cover organs with a moist sterile dressing.

• Transport immediately.

Impaled Objects (1 of 2)

• Do not attempt to move or remove object.

Impaled Objects (2 of 2)

• Control bleeding and stabilize object.

• Tape a rigid item over object to prevent movement.

• Transport to hospital carefully.

Amputations

• Immobilize partial amputation with bulky dressings and splint.

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

• Put bag in cool container filled with ice. Do not let object freeze!

• Transport severed part with patient.

Neck Injuries (1 of 2)

• An open neck injury can be life threatening.

• Air can get into the veins and cause an air embolism.

Neck Injuries (2 of 2)

• 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

• Burns account for over 10,000 deaths/year.

• Burns are 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

Depth of Burns (2 of 3)

• Partial-thickness (second-degree) burns

• Involve epidermis and some portion of dermis

Depth of Burns (3 of 3)

• Full-thickness (third-degree) burns

• Extend through all layers of skin

Extent of Burns

Critical Burns (1 of 2)

• Full-thickness burns involving hands, feet, face, upper airway, genitalia, or circumferential burns of other areas

• Full-thickness burns covering more than 10% of total body surface area

• Partial-thickness burns covering more than 30% of total body surface area

• Burns associated with respiratory injury

Critical Burns (2 of 2)

• Burns complicated by fractures• Burns on patients younger than 5 years old or older

than 55 years old that would be classified as moderate on young adults

Moderate Burns

• Full-thickness burns involving 2% to 10% of total body surface area excluding hands, feet, face, upper airway, or genitalia

• Partial-thickness burns covering 15% to 30% of total body surface area

• Superficial burns covering more than 50% of total body surface area

• Full-thickness burns involving less than 2% of the total body surface area

• Partial-thickness burns covering less than 15% of the total body surface area

• Superficial burns covering less than 50% of the total body surface area

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.

• He found employee with ankle pinned under tire, while other side of car was still on the jack.

• He used the jack to lift the car off the employee, then pulled patient clear of car.

• Hot antifreeze drained over patient’s thigh.• Patient denies loss of consciousness.

Scene Size-up

• In addition to BSI, what are some considerations at the scene?

• Are there any other hazards?• What is the MOI?

You are the provider continued (1 of 3)

• His respiratory effort is rapid and lips are pursed.• Inspection and palpation of the chest is

unremarkable. • A quick check of radial pulse indicates that it is

rapid.• There is no obvious external bleeding.

You are the provider continued (2 of 3)

• You and your partner opt to perform a rapid physical exam.

• Partner maintains c-spine precautions.• You determine no life-threatening injuries.• You expose his burns.• One thigh is completely reddened with a fist-sized

blister.• Patient denies taking medications.• States he is allergic to penicillin and has no past

medical history

You are the provider continued (3 of 3)

• At what point would you take vital signs?• When should you start oxygen?• How much would you administer? What type of

device would you use?• What degree of burn does the patient have?• Given the location and area, is this burn life

threatening?• How do you treat this burn?
