Study Notes
Types of Bleeding
- Venous bleeding presents with dark red blood flowing steadily from a wound.
- Arterial bleeding is characterized by bright red blood that spurts with each heartbeat.
Injury Complications
- Compartment syndrome occurs when edema compresses nerves and circulation in an extremity, compromising function.
Wound Types
- Partial avulsion refers to a flap of skin that is torn away but not completely removed.
- An avulsion involves complete tearing away of skin.
Bruising and Skin Injuries
- A contusion is identified by black-and-blue discoloration or bruising of the skin.
Burn Assessment
- Dry sterile dressings are recommended for thermal burns to the eyes.
- Superficial burns are characterized by dry, red skin without blistering.
Fire-Related Injuries
- Major concern in burn patients may include inhalation injury, especially in cases of smoke exposure.
- Referral to a burn center is not typically required for superficial burns covering 10% or less of body surface area.
Skin Layers and Functions
- The epidermis acts as a barrier between the body and the external environment.
- The subcutaneous layer aids in body temperature regulation.
Burn Classifications
- First-degree burns are classified as superficial burns, while partial-thickness burns present blisters.
- The rule of nines allocates approximately 9% for identifying body surface areas affected by burns.
Calculating Burn Area
- A patient with blisters on the chest and circumferential burns on the lower extremities may have around 45% body surface area burned.
- Burns covering the entire anterior chest, abdomen, neck, and face total approximately 27% of the body.
- The rule of palm can be effectively used to estimate burn areas when they are smaller.
Severity of Burns
- Patients with both partial- and full-thickness burns present severe injuries, especially if exhibiting white and charred burns with pain and blistering.
- Moderate burns are classified as partial-thickness burns.
