Two principal layers of the skin
Epidermis and dermis
Dead tissue
May have a bad odor
Gangrene
Our first step to managing a bleed
Direct pressure
Extend through all skin layers and may involve subcutaneous layers, muscle, bone, and internal organs
Full-thickness burns
Three most common types are alpha, beta, and gamma.
Radiation burns
Tough, external layer that forms a watertight covering
Epidermis
Caused by infection with Clostridium tetani
Tetanus
A tool to control a arterial hemorrhage
tourniquet
Involve only the top layer of skin, the epidermis
Superficial burn (first degree)
Occur when the body, or a part of it, completes a circuit connecting a power source to the ground
Electrical burns
Inner layer of the skin that lies below epidermis
Dermis
Involves death of tissue from bacterial infection
Caused by various infecting organisms, but most often group A Streptococcus
Necrotizing fasciitis
Treat by using RICES
Rest
Ice
Compression
Elevate
Splint
Involve the epidermis and some portion of the dermis
Partial-thickness burn (second degree)
Can occur whenever a toxic substance contacts the body
Chemical burns
Protects the body
Sensation
Regulate temperature
Skin functions
Tissue necrosis develops and results in release of harmful products into the bloodstream when the limb is freed from entrapment
Crush syndrome
Place patient supine, initiate IV therapy, give high-flow oxygen, keep warm, and provide prompt transport.
Managing signs of shock
Three zones of a burn
Zone of coagulation
Central area of the skin that suffers most damage
Zone of stasis
Peripheral area surrounding zone of coagulation
Zone of hyperemia
Area least affected by thermal injury
Type of poisoning that occurs with smoke inhalation
Hydrogen cyanide poisoning
Caused when a body part rubs or scrapes across a rough or hard surface
Abrasion
Characterized by pain that is out of proportion to the injury
Compartment syndrome
Extremities that are painful, swollen, or deformed should be
Splinted
Depth of the burn
Extent of the burn
Critical areas involved (face, upper airway, hands, feet, genitalia)
Preexisting medical conditions or other injuries
Patient younger than 5 years or older than 55 years
Five factors to determine the severity of a burn
Can occur when burning takes place in enclosed spaces without ventilation
Inhalation burns
Smooth or jagged cut caused by a sharp object or a blunt force that tears tissue
Laceration
Blue or black discoloration
Ecchymosis
These clues may tell you, you may have an
Erythema
pus
warmth
edema
local discomfort
Infection
Based on dividing the body into 11 sections, each representing approximately 9% of the TBSA
Rules of nines
4 mL×kg body weight×%TBSA4 mL cross kg body weight cross % TBSA
Parkland or Consensus burn formula
Separates various layers of soft tissue so that they hang as a flap
Avulsion
Characterized by a history of blunt trauma, pain at the site of injury, swelling beneath the skin, and discoloration
Closed injuries
a type of trauma where the skin or mucous membrane is broken, torn, or punctured, exposing underlying tissues, muscles, or bones to the external environment
Open injuries
Uses the size of the patient’s palm (including the fingers) to represent approximately 1% of the patient’s TBSA
Rule of palms
Caused by heat and affects exterior portions of the body
Thermal burns
