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
Protection from external injury
Temperature control
Control of body fluids
Sensory organ
Determines identity

What is a burn?
Cutaneous injury caused by heat, electricity, chemicals, friction, or radiation.
![Page 7: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/7.jpg)

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
![Page 9: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/9.jpg)
Superficial Partial Thickness
Entire epidermis & portion of dermis (Papillary dermis)
Homogenous pink Painful Blisters Blanches Hair usually intact Does not scar, may pigment
differently
![Page 10: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/10.jpg)

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
![Page 12: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/12.jpg)

Where do burns occur
![Page 20: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/20.jpg)
Admissions by age
![Page 21: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/21.jpg)
% of admissions vs. burn size
![Page 22: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/22.jpg)
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
![Page 23: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/23.jpg)
Inhalation injury diagnosis
Closed-space fire Face burns
![Page 24: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/24.jpg)
Terminology
Inhalation injury “nonspecific”– Thermal injury
Upper airway Heat and toxic fumes
– Local chemical irritation Throughout airway Primarily toxic fumes
– Systemic toxicity CO
![Page 25: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/25.jpg)
Signs and symptoms
Lacrimation Cough Hoarseness Dyspnea Disorientation Anxiety Wheezing
Conjunctivitis Carbonaceous
sputum Singed hairs Stridor Bronchorrhea
![Page 26: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/26.jpg)
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
![Page 27: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/27.jpg)

Poison management = CO
500 unintentional deaths each year Persistent Neurologic Sequelae
– May improve over time
Delayed Neurologic Sequelae– Relapse later
![Page 29: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/29.jpg)
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
![Page 30: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/30.jpg)
Poison management = CO
Treatment– CO level means nothing to predict outcome– Length of hypoxia is the determining factor– Oxygen– HBO
No studies show benefit in treatment
![Page 31: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/31.jpg)

Determine Burn Severity
% BSA involved Depth of injury Age Associated/pre-existing
disease or illness Burns to face, hands,
genitalia
![Page 33: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/33.jpg)
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
![Page 34: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/34.jpg)
Burn Extent
Total Body Surface Area (TBSA)?
Rule of nines Lund and Browder chart Patients palm = about 1% TBSA
![Page 35: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/35.jpg)
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.
Burn diagrams illustrate adult – child differences

Extent of Burns

Burn Depth
Factors
Temperature Duration of contact Dermal thickness Blood supply Special Consideration: Very young and
very old have thinner skin
![Page 39: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/39.jpg)
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)
![Page 40: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/40.jpg)
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)
![Page 41: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/41.jpg)
Pain control
![Page 42: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/42.jpg)
Ice Pack-----DO NOT USE EVER
DOES NOT– Reverse temperature– Inhibit destruction– Prevent edema
DOES– Delay edema– Reduce pain
![Page 43: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/43.jpg)
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
![Page 44: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/44.jpg)
Medication
Medications– Opioids– Narcotics– Pain medications– IV Analgesia
![Page 45: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/45.jpg)
Resuscitation
![Page 46: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/46.jpg)
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
![Page 47: Initial Care of Burns](https://reader036.vdocuments.site/reader036/viewer/2022062519/56815570550346895dc33be0/html5/thumbnails/47.jpg)
Field resuscitation
Start IV with LR, through burn OK
– < 6 years = 125mL/hr– 6-13 years = 250mL/hr– >13 years = 500mL/hr

ABA Burn Referral Criteria
The ABA identifies the following as injuries requiring a Burn Center referral:
2nd degree burns > 10% TBSA Burns to face, hands, feet, genitalia, perineum, major joints 3rd degree burns Electrical injury Chemical burns Inhalation injuries Burns accompanied by pre-existing medical conditions Burns accompanied by trauma, where burn injury poses greatest
risk of morbidity or mortality. Burns to children in hospitals without pediatric services. Patients with special social, emotional or rehabilitative needs.
