Objectives




Discover who’s getting burned?
Discuss Burn pathophysiology.
Understand why some treatments are better
than others.
Review treatment options.
Skin Structures



Epidermis – outermost layer of keratinized cells
Dermis – contains skin appendages, vascular supply
and nerve endings
Subcutaneous Tissue
Functions of the Skin

Barrier to infection

Control of body fluids

Protection from external
injury

Sensory organ

Determines identity

Temperature control
What is a burn?

Cutaneous injury caused by heat, electricity,
chemicals, friction, or radiation.
Burn Depth
First Degree Burns





Epidermis affected only
Red or pink, dry, painful,
blanches to touch
Epidermis is intact
Spontaneous healing
within 7 days. Outer
injured epithelial cells peel
Seldom clinically
significant
Superficial Partial Thickness







Entire epidermis & portion of
dermis (Papillary dermis)
Homogenous pink
Painful
Blisters
Blanches
Hair usually intact
Does not scar, may pigment
differently
Sup 2nd degree
Deep partial thickness







Reticular dermis
Mottled red and white
Not painful to pinprick or pressure
Does not blanch
Heals > 3 weeks
Usually scars
Need to excise and graft
Deep Partial Thickness
Deep dermal
Full Thickness:
3rd degree




May go into fat or
deeper
Red, white, brown,
black
Inelastic and leathery
painless or numb
Heals only from the
periphery
Always excise and graft
Full-thickness
Etiology
Types of burns
Circumstances of injury
Where do burns occur
Admissions by age
% of admissions vs. burn size
Inhalation Injury
Exposure to heat and toxic products of combustion


50% of fire deaths are related to inhalation injuries
Asphyxia/Carbon Monoxide displacement of oxygen
Inhalation injury diagnosis


Closed-space fire
Face burns
Terminology

Inhalation injury “nonspecific”
–
Thermal injury


–
Local chemical irritation


–
Upper airway
Heat and toxic fumes
Throughout airway
Primarily toxic fumes
Systemic toxicity

Cough
Hoarseness
Dyspnea
Disorientation
Anxiety
Wheezing

Conjunctivitis
Carbonaceous
sputum
Singed hairs
Stridor
Bronchorrhea
Pathophysiology


The main factor responsible for mortality in
thermally injured patients
Carbon monoxide the most common toxin
–
–
200 times greater affinity
Competitive inhibition with cytochrome P-450
Poison management = CO


500 unintentional deaths each year
Persistent Neurologic Sequelae
–

May improve over time
Delayed Neurologic Sequelae
–
Relapse later
Carbon Monoxide Poisoning





10% COHb – asymptomatic, seen most often
in smokers, truck drivers, traffic police
20% COHb - headache, nausea, vomiting,
loss of dexterity
30% COHb - confusion & lethargy, possible
ECG changes
40-60% COHb - coma
60% + - usually fatal
Poison management = CO

CO level means nothing to predict outcome
Length of hypoxia is the determining factor

Depth of injury
Age
Associated/pre-existing
disease or illness
Burns to face, hands,
genitalia
Difficulties with accurate initial
assessment of burn size & depth


Soot, blisters, adherent clothing or debris
obscure wound
Burns are dynamic…Progression is always a risk
Burn Extent
Total Body Surface Area (TBSA)?

Patients palm = about 1% TBSA
Extent of Burn :“Rule of Nines”



Adult anatomical areas
= 9% BSA (or multiple)
Not accurate for infants
or children due to larger
BSA of head & smaller
BSA legs.

adult – child differences

Extent of Burns
Patient’s palmar surface (hand + fingers) = 1% TBSA
Burn Depth
Factors





Temperature
Duration of contact
Dermal thickness
Blood supply
Special Consideration: Very young and
very old have thinner skin
Burns begin at 44 degrees C

6 hours for burns to occur at
111 degrees F (44 C)

1 second of burns to occur at
140 degrees F (60 C)
Time For Full Thickness
Burns To Occur In Scalds

5 seconds in water @ 140 F (60 C)

30 seconds in water @ 130 F (55 C)

5 minutes in water @ 120 F (49 C)
Pain control
Ice Pack-----DO NOT USE EVER

DOES NOT
–
–
–

Reverse temperature
Inhibit destruction
Prevent edema
DOES
–
–
Delay edema
Reduce pain
Non-medication methods

Cover burns with plastic wrap
–
–
–
Wet dressings will stick and cause more pain
Other burn dressings are expensive and not
necessary
Quik Clot is expensive and will not provide any
patient benefit
Medication

Medications
–
–
–
–
Opioids
Narcotics
Pain medications
IV Analgesia
Resuscitation
IV access





< 15% TBSA – oral resuscitation
15 – 40% TBSA – one large bore IV
> 40% -- two large bore IV’s
IV’s should be in the upper extremities
Suture IV’s started through burns
Field resuscitation

Start IV with LR, through burn OK

< 6 years = 125mL/hr
6-13 years = 250mL/hr
>13 years = 500mL/hr
