Introduction
Incidence of Burns
½ million seek medical care annually
Approximately 40K are hospitalized Where do most burn trauma injuries
occur? Bonus' Site - KitchenOilFire.wmv
04/19/23 3
Types of Burn Injury
Thermal Chemical Electrical Radiation
04/19/23 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
04/19/23 5
Thermal Burns (cont)
Cover patient with a clean cover
Do NOT pull off clothing; instead cut off clothing if possible…WHY?
Keep NPO and transport
04/19/23 6
Chemical Burns
Remove person from contact with agent
Flush with water continuously
Remove affected clothing if possible
04/19/23 7
Electrical burns Coagulation necrosis Severity depends on voltage, amount of
resistance, time,
and current
pathways.
Electrical Burn–Back
Fig. 25-2 B
04/19/23 9
Frequently only entry (yellow-white) and exit (blow out) wounds are visible
Extensive tissue damage is masked
How can we evaluate “masked tissue damage”???
04/19/23 10
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
04/19/23 11
Interventions for Electrical Burns Turn off source of

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
04/19/23 24
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!

04/19/23 26
Some Questions…..
The nurse knows that in a patient who has full thickness burns, that the burns must involve the:
a) Muscle
b) Dermis
c) Tendons
d) Bone
A 40 year old male sustains burns to his anterior torso following an explosion of a fuel tank. The burned area is brown and leather like. The client does not c/o pain. The nurse should conclude that the client has burns that are:
a) superficial partial thickness b) moderate partial thickness c) deep partial thickness d) full thickness
04/19/23 28
What are the Priorities in this patient??? Is this patient a candidate for a
major burn center?

Nursing Care During Emergent Phase Impaired Gas Exchange r/t
tissue hypoxia secondary to carbon monoxide poisoning
Note: CO poisoning is the MOST immediate cause of death from fire.

Signs & Symptoms of Carbon Monoxide Poisoning Edema of Airway Hoarseness Dysphagia Stridor Copius Secretions usually
black tinged Skin will appear cherry red
04/19/23 31

Interventions for CO Poisoning: Assess for S&S CO poisoning (mild to
severe) Humidified O2 100% via face mask High Fowler’s Position TCDB q 1 hour Intubation & Ventilation Bronchodilators for bronchospasm One other thing…..does anyone
know???
04/19/23 34

½ total amount given 1st 8 hours ¼ total amount given next 8 hours ¼ total amount given next 8 hours
04/19/23 43
Okay Nurses Let’s Calculate
What would the fluid replacement be for a patient who weighed 60kg and had 30% TBSA burned???
1st 8 hours= _____ or ____ml/hr 2nd 8 hours= _____ or _____ml/hr 3rd 8 hours= ______ or _____ml/hr

Emergent Phase (cont)
Monitor Electrolytes and Hematocrit; tells you about fluid shift. What should Hct be doing as
time progresses???
Using the Parkland formula, a client who has full and deep partial thickness burns to 30% of his body is to receive 6000ml of fluid over the next 24 hours. You would administer:
1/3, 1/3 and 1/3 during each 8 hour period 1/2, 1/4, and 1/4 during each 8 hour period 1/4, 1/4, 1/4 and 1/4 during each 6 hour period 1/8, 1/8, 1/4, and 1/2 during each 6 hour period
