Integumentary Flashcards
Thermal burns
- Flames, hot liquids, steam, semisolids (tar), or hot objects
- Most common
Chemical Burns
Strong acids, alkalis, or organic compounds
Electrical Burns
Exposed or faulty electrical wiring, high-voltage power lines, or lightning
radiation burns
- Exposure to a radio-active source
Burn Risk Factors
- Age
- Smoking
- Inadequate adult supervision
- Psychomotor disorders (e.g., impaired judgment or mobility)
- Rural location
- Mobile home residence
- Occupation
- Lack of smoke detectors
- Fireworks
- Misuse of cigarettes
- Bringing peace, freedom, justice and security to my new empire
Burn severity depends on
- Depth
- Age
- Size - percentage of total body surface area (TBSA)
- Location
- General health
- Mechanism of injury
Burns that require medical intervention are a combo of
partial and full thickness burns
- Rule of Nines
- For adults
- 9% head and neck
- 9% each arm
- 18% each leg
Extensive burns (25% or more of the TBSA)
Response is systemic - The systems more obviously affected
Cardiovascular
Renal
Gastrointestinal
Immune
Respiratory
Smaller burns
Body’s response to injury is localized to the injured area
In burns, face may have associated
corneal abrasions
CV Changes
Occur ________
Vasoactive substances released with _______
Immediately (burn shock)
cell necrosis
Extensive Burns
Generalized body edema in both ________
Intravascular blood volume _________
HR __________
burned and non-burned tissue
decreases
increases
Extensive Burns
- CO falls —>
- return to normal —> increases approximately
24 hour after the injury
Burns
Renal and GI
Oliguria and intestinal dysfunction
Burns
Immune System
Depressed —> increasing the risk of infection & sepsis
Burns
The Respiratory System
- Pulmonary artery hypertension
- Decreased lung compliance
Chemical Burns associated with
system toxicity
- Electrical Burns
- Heat is generated as the electricity travels through the body
- Resulting in
- Heat is generated as the electricity travels through the body
internal tissue damage
Electrical burns
Cutaneous burn injuries may be
- negligible, but soft tissue and muscle damage. may be
extensive
Electrical
Alternating current more dangerous than
direct
Electrical burns
Other significant injuries
Long-bone or vertebral compression fractures
SCI or TBI
- Burn location influences injury severity
- Head, neck, and chest frequently have associated
pulmonary complications
Burns
Hands and joints can result in
permanent physical and vocational disability
