  • Soft tissue injuries
    Anything other than cartilage or bones
  • Soft tissue injuries
    • Range in severity from scrape or cut to life-threatening injuries
    • Don't be distracted by open wounds we can see - e.g liver, brain, etc
  • Soft tissue
    Skin, muscles, tendon, fascia, nerves, fat, blood vessels
  • Elderly and very young
    • Have skin that is more easily compromised (especially in eyelids, lips, ears)
  • Layers of skin
    • Epidermis
    • Dermis
    • Subcutaneous layer
    • Fascia (tough)
    • Muscle
  • Skin functions
    • Barrier against infection
    • Sensation
    • Temperature regulation
    • Fluid regulation
  • Types of soft-tissue injuries
    • Closed injuries
    • Open injuries
    • Blast injuries
    • Burns
  • Closed injuries
    • Typically results from blunt trauma
    • Usually no break in skin
  • Signs and symptoms of closed injuries
    • Pain and tenderness
    • Deformity
    • Swelling
    • Ecchymosis
  • Types of closed injuries
    • Contusion (bruise, no break in skin; minor blood vessels compromised; not a lot of swelling)
    • Hematoma (blood collected within damaged tissue or in a body cavity)
  • Crush syndrome
    1. Decreased circulation to anaerobic metabolism
    2. Generates lactic acid
    3. Increased cellular wall permeability
    4. Cellular death
    5. Increased blood toxicity distal to crushing force
  • Crush injury
    • Alert and conscious patient can rapidly deteriorate
    • Cardiac arrhythmias/arrest
    • Renal failure
    • Respiratory distress
    • Liver disease
  • Assessment of crush injury
    • Larger area of body entrapped for prolonged time (>4 hours)
    • Patient may appear stable
    • Distal pulses may be difficult to assess
    • Numbness may mask pain
  • Patient management for crush injury
    1. ALS - physician at scene if possible
    2. ABCs - oxygenate
    3. Assess for crush injury, not entrapment duration
    4. Be prepared for deterioration after patient is freed
    5. BVM, AED
    6. Rapid transport
  • Compartment syndrome

    • Results from the swelling that occurs whenever tissues are injured
    • Look for weakened circulation
    • More pain than would result from visible injury
  • Severe closed injuries can also damage internal organs
  • Open injuries
    Protective layer of skin is damaged
  • Types of open injuries
    • Abrasions (not typically life threatening, but very painful; usually scrapes away upper layer of epidermis)
    • Lacerations (linear)
    • Avulsions (tearing away of a piece of skin)
    • Penetrations (stabbings or shootings often result in multiple penetrating injuries)
  • Treatment for open injuries
    1. Abdominal dressings w/o saline so bleeding stops
    2. Bulky dressing to keep things in place
  • Care for blast injuries
    1. BSI
    2. xABCs
    3. Control hemorrhaging first
    4. Treat for shock
    5. Apply cold splint/immobilize
  • Impaled objects
    Only remove object when:
    Object penetrates the cheek with airway compromise
    Object is in the chest and interferes with CPR
    Object prevents the transport of patient - can anything be done so object doesn't have to be removed
  • Open neck injuries
    Can be life threatening
    Air embolism - air gets in circulation
  • Treatment for open neck injuries
    Occlusive dressing - things that are not semipermeable; covered with sterile dressing; bandage into place
    Apply pressure - do not apply pressure to both carotid arteries at the same time
  • Burns
    Occur when the body receives more radiant energy than it can absorb
    Sources include heat, toxic chemicals, and electricity
  • Complications of burns
    • Infection
    Hypothermia
    Hypovolemia
    Shock
  • Factors affecting burn severity
    • Depth of burn
    Extent of burn
    Critical areas involved (face, upper airway, hands, feet, genitalia)
    Preexisting medical conditions
    Patient age (<5, >55)
  • Burn depth
    • Superficial or first degree burns (epidermis is burned)
    Partial-thickness or second degree burns (epidermis and some portion of the dermis; blisters are hallmark)
    Full thickness or third degree burns (extend through all skin layers)
  • Thermal burns
    Caused by heat; most commonly caused by scalds or open flames
  • Inhalation burns
    Can occur when burning takes place in enclosed spaces without ventilation
    Paper airway damage associated with the inhalation of superheated gases
    Lower airways damage associated with the inhalation of chemicals and particulate matter
  • Emergency medical care for burns
    Stop burning process
    Remove any clothing, jewelry, etc
    ABCs - humidified air, ALS needed?
    Consider transport to a burn center
    Aeromedical transport?
    For burns <10% BSA (body surface area): Moistened sterile dressing
    For burns >10% BSA: Dry sterile dressing (want to prevent hypothermia)
  • Abdominal and genitourinary injuries
    Mechanism of injury is important
    Significant trauma to the abdomen can occur from blunt trauma, penetrating trauma, or both
    Injuries to the abdomen that go unrecognized are not repaired in surgery and are a leading cause of traumatic death
  • Abdominal quadrants
    • RUQ - liver, gallbladder, duodenum, pancreas
    LUQ - stomach and spleen
    LLQ: descending colon, left transverse colon
    RLQ: larger and small intestine, appendix
  • Hollow organs
    Stomach, intestines, ureters, bladder
    When ruptured or lacerated, contents spill into peritoneal cavity
    Can cause intense inflammation and infection such as peritonitis
  • Abdominal injuries
    • Closed abdominal injuries
    Open abdominal injuries
  • Open abdominal injuries
    Foreign objects enters abdomen and opens peritoneal cavity to the outside
    Damage depends on velocity of object - low velocity (knives, other edged weapons), medium velocity (smaller caliber handguns and shotguns), high velocity (rifles and handguns)
  • Hollow organ injuries
    Often have delayed signs and symptoms
    Spill contents into abdomen
    Infection develops, which can take hours or days
    Stomach and intestines can leak highly toxic and acidic liquids into peritoneal cavity
  • Solid organ injuries
    Can bleed significantly and cause rapid blood loss
    Can be hard to identify from physical exam
    Liver is the largest organ in abdomen and is vascular, injuries can lead to hypoperfusion
    Spleen and pancreas are vascular and prone to heavy bleeding
  • Assessment of abdominal injuries
    • Difficult - rely on mechanism of injury
    Causes of injury may be apparent but resulting tissue damage may not be
    Patient may be overwhelmed with more painful injuries
    Some injuries develop and worsen over time
  • Physical examination of abdomen
    Visually inspect for bleeding
    Expose injuries for visual assessment
    Position of comfort
    Examine entire abdomen
    DCAP-BTLS
    Assess for rigidity, distention
    Inspect and palpate kidney area for tenderness, bruising, swelling, or other trauma signs
  • Management of closed abdominal injuries
    Monitor and evaluate for progression into shock
    Administer oxygen/assist ventilations if necessary
    Consider ALS
