used in the treatment
of burns.
Annual Incidence
 450,000 requiring medical
treatment
 3,500 fire and burn deaths
 45,000 hospitalizations
Annual Incidence
 Cost: millions to billions in
dollars, immeasurable in
emotional distress to victims
and families
Where Burns Happen
 Majority in home: 86%
 #1: careless cigarettes
 also water >140° F,
cooking surfaces,
combustibles, space
heaters, chemicals, unsafe
electrical wiring, etc.
Where Burns Happen
 Industry: 10%
 Street/highway: 8%
 Farm and other/unknown:
16%
Financial/Community
Impact
 Care is specialized,
expensive [$3,000-5,000 per
day in burn intensive care
unit (BICU)]
Financial/Community
Impact
 Victim off work, nonproductive for weeks to
months
 Family roles are disturbed
for weeks to years
Financial/Community
Impact
 Prevention is cheaper and
easier!
Mortality/Morbidity in
BICUs
 Survival rate: 94.8%
 Gender: 70% male, 30%
female
 Ethnicity: 63% Caucasian,
17% African-American, 14%
Hispanic, 6% other
Mortality/Morbidity in
BICUs
 Admission cause: 42%
fire/flame, 31% scald, 9%
contact, 4% electrical, 3%
chemical, 11% other
Prevention of Burns
 Hot water heaters: <120° F
 Bath water: about 100° F
 Anti-scald devices on bath
and shower heads
 Supervision of small children
and elders
Prevention of Burns
 Grab bars in showers for
impaired mobility
 NO children in cooking area
 While cooking, all pot
handles and electric cords
out of reach
Prevention of Burns
 Safety handles/knobs on
stoves
 Do not use open flame
heaters
 Meals: hot items in center of
table
Prevention of Burns
 Meals: non-slip placemats
with toddlers
 Meals: no tablecloths with
toddlers or when anyone
using crutches or
wheelchairs
Prevention of Burns
 Hot liquids
 don’t carry while carrying
child
 not on low tables
 Wheelchair: use a tray to
carry hot foods/drinks
Prevention of Burns
 Microwave
 use extreme caution with
plastic wrap and hot
containers
 stir all food before serving
 Fires: no gasoline, aerosols,
or plastic
Prevention of Burns
 Carburetors: don’t prime
with gasoline
 Open flames: don’t combine
with gasoline/kerosene
Prevention of Burns
 Electrical
 use extreme care
 if in doubt, don’t touch
 don’t use questionable
outlets
Prevention of Burns
 Chemical
 use protective gear with all
 never combine bleach and
ammonia or products
containing them
Prevention of Burns
 Christmas trees
 never leave lights
unattended
 use mini-lights only
 Smoke alarms: check battery
monthly
Prevention of Burns
 Children playing with fire:
NO
 Don’t refuel a hot lawn
mower engine
Prevention of Burns
 Sunscreen, hats, long
sleeves for prolonged
exposure
 Routinely check fireplaces,
heaters/furnaces
Prevention of Burns
 Use cool mist vaporizers
with children/disabled/elders
 Flameproof/retardant clothes
for sleep, Halloween, etc.
 Supervise kids carefully
around open flames
Mortality Estimates
 Mortality estimate: %TBSA +
age
 Inhalation injury:
2(%TBSA + age)
 TBSA: total body surface
area (burned)
Estimate Severity
 Size (%TBSA)
 Depth
 Location (hands, feet,
genitalia, face more severe)
 Age [<2 years (yrs) and
>65 yrs more severe]
Estimate Severity
 Past medical history (chronic
disease)
 Concomitant injuries
Minor vs. Major
 Minor: treat at home
 Moderate: community
hospital
 Major: burn unit
Minor vs. Major
nd

 Minor: 2 degree <15% or 3
degree <3% with no other
concerns

 Neuro: alert, active 1 1-2
hours (hrs), then diminished

Body Response to
Burns
 Emotional and social

 Fluid
shift in burns
 Inflammation opens capillary
pores causing leak of water,
albumin, fibrin, electrolytes
to 4-15x normal
