Study Notes
Skin and Functions
- The germinal layer of the epidermis contains pigment granules responsible for skin color.
- Key functions of the skin include protection, sensation, and thermoregulation, but it does not produce antibodies.
Soft Tissue Injuries
- A hematoma forms when large blood vessels under the skin are compromised.
- Compartment syndrome may present with pain during passive movement of the affected area.
Case Studies
- A patient with cold, pale, and deformed arm post-crushing injury, absent radial pulse, raises concern for compartment syndrome.
- Open soft-tissue injuries pose a significant risk for infections in addition to external bleeding.
Penetrating Injuries
- External bleeding could be minimal in penetrating injuries, yet internal damage may be severe.
Assessment and Transport
- In cases of widespread contusions and weak pulse, oxygen administration and prompt transport are critical.
- Clinical signs like cool, pale skin in a conscious but restless patient indicate possible internal bleeding.
Evisceration and Impalements
- Abdominal evisceration occurs when internal organs are displaced outside the body through a wound.
- For a construction worker with an impaled object and no pulse, control bleeding, initiate CPR, stabilize the object, immobilize the spine, and transport promptly.
Bites and Burns
- Human bites carry a risk of severe infections due to various bacteria and viruses.
- Burns are classified by depth and severity, with severe burns often encompassing multiple burn degrees.
- In children, superficial and partial-thickness burns can encompass significant body surface area; 30% for a 5-year-old girl burned by boiling water.
Electrical Injuries
- For electrical damage to occur, a complete circuit must exist between the electrical source and the ground.
Fire-related Injuries
- In burn victims from fire, signs like singed nasal hairs and sooty sputum indicate a risk of airway swelling.
Treatment Protocols
- Avoid creams, lotions, or antiseptics when treating partial-thickness burns.
- Dressings and bandages serve various roles but do not immobilize injuries.
- According to the rule of nines, burns covering the anterior aspect of arms and chest account for 18% of body surface area.
Wound Care
- Wounds with abdominal evisceration should be covered with moist, sterile gauze secured with an occlusive dressing.
Neurological Signs
- Confusion, slurred speech, and a large forehead hematoma following head trauma may suggest significant injury requiring immediate attention.
