Introduction

Incidence of Burns

450K in U.S. seek medical care annually

Approximately 45K are hospitalized Which setting do most burn trauma

injuries occur? How many Burn Trauma centers in

U.S.?

04/20/23 3

Types of Burn Injury

Thermal Chemical Electrical-what type considered

here? Which state has highest incidence of ____ injuries?

Radiation

04/20/23 4

Thermal Burns( Most Common) Caused by flame, flash, scald, or

contact burns

STOP & DROP Roll to shut off O2 supply to

fire Flush or immerse in cold

water DO NOT use ICE on deep

burns, just localized, superficial burns

04/20/23 5

Chemical Burns

Remove person from contact with agent

Flush with water continuously

Remove affected clothing if possible

Alkaline agents worse than acid, process keeps going

04/20/23 6

Electrical burns Coagulation necrosis Severity depends on voltage, amount of

resistance, time,

and current

pathways.

Electrical Burn–Back

04/20/23 8

Frequently only entry (yellow-white) and exit (blow out) wounds are visible

Current practice: Now refer to contact points vs entry and exit points.

Extensive tissue damage is masked

How can we evaluate “masked tissue damage”???

04/20/23 9

Electrical Burns (cont) Patient at risk for arrhythmias

due to _____, metabolic acidosis due to _____, and acute tubular necrosis due to ______.

Current can be so strong to

fracture long bones and cause respiratory muscles to contract

Medical/Nursing Management of Burns I. Emergent Phase

Period of time from onset of burns to the beginning of fluid remobilization

Usually lasts 24-48 hours

04/20/23 20

Emergent Phase (cont)

Also called FLUID ACCUMULATION PHASE

The greatest initial threat to a major burn victim is hypovolemic shock

Let’s do the Patho on p. 479 Lewis…this is a DING DING!

Instruct client on skin care:

Skin will itch, be dry, have a tight feeling

Use Vaseline Intensive Care ES lotion, mild soaps

Use Benadryl for itchingAvoid direct sunlight (will cause
