Week 14: Burns ASYNCHRONOUS
Burns
Burn: “an injury to the tissues of the body caused by heat, chemicals, electrical current, or
radiation. The resulting effects are influenced by the temperature of the burning agent, the
duration of contact time, and the type of tissue that is injured” (Tyerman et al., 2023, p. 518).
Burn prevention has shifted from an individual level based on blaming or ostracizing the
individual to burn prevention programs that use legislative changes to reduce environmental
hazards and risks.

Types of Burn Injuries:
Thermal (Heat): “caused by flame, flash fire, scald, or contact with hot objects. They are the
most common type of burn injury” (Tyerman et al., 2023, p. 519).
examples : liquid steam fire
, ,
Electrical: “result from intense heat generated from an electric current and are considered the
most severe type of thermal trauma, generally associated with greater damage of functional
structures, such as muscle and bone” (Tyerman et al., 2023, p. 520).

to the tissues of the respiratory tract . . . smoke inhalation injuries are a major predictor of
mortality in burn patients” (Tyerman et al., 2023, p. 519).

Classification of Burn Severity & Type:
Treatment is individualized based on the severity of the burns, including the depth of the burn,
the percentage of TBSA, the location of the burn, and patient risk factors.

1. Burn Depth: classified by type of tissue damaged 2) dermis
3) hypodermis
