Integumentary System
4 Main Causes of Burns
Fire
Chemical
Radiation
Electricity
Burns are evaluated by…
1. The extent or % of body surface burned
2. The depth of the burn
Estimating body surface area
Rule of 9’s pg 167
Body is divided into
11 areas of 9% =99%
Area around the
genitals makes up the
last 1%
Total area burned is
estimated by sight
what areas are burned
and comparing to the
chart.
Depth of burns
 Depends on the tissue layers of skin
involved
1. First Degree burn (typical sunburn)
 Causes minor discomfort
 Some reddening of the skin
 Burned surface layers may peel in 1-2 days
 NO blistering occurs
 Minimal tissue destruction
 “Partial thickness” burn
2. Second Degree burn
 Involves deep epidermis and upper dermis
 Damage to sudoriferous glands, hair follicles,
& sebaceous glands
 Blisters, severe pain, & edema occur
 Scarring is very common
 “Partial thickness” burn
3. Third Degree burn
Also known as “Full Thickness” burn
Destruction of both the epidermis & dermis
leading to tissue death
Burn may involve muscles and bones
This burn is insensitive to pain…why?
Nerves are burnt off
Concerns with Burns
Heat Loss
Body heat
Fluid Loss
Barrier holding fluid in
Infection
Open wounds
Skin Grafting:Move skin to burned area
Autografting
 Skin from own body
Advantages:
 Own skin
Disadvantages
 2 scars
Heterografting
 Skin from another
individual
Advantages:
 1 scar
Disadvantages
 Different pigments
 Could be rejected
