Burns Flashcards
4 things to know about every burn patient
Extent, depth, age, associated illness or injury
Rule of 9 for calculating burn area
front of leg = 9%, lower front of abdomen = 9%, whole arm = 9% upper front of chest = 9%, whole head = 9%
1st degree burn
epidermis, red or grey with cap refill, painful, dry, not blistered initially (superficial burns w/o blister) heals in 3-5d
2nd degree burn - superficial
blistered, epidermis + upper dermis, may have waxy appearance/wet, pink to red, blanches, heals 10-21d
3rd degree burn
progressive loss of adnexal structures (hair, sweat glands, smooth skin) (waxy white or gray with scarring), loss of pain
23-yo man presents to the ER with what appears to be 2nd degree burns to the complete circumference of both legs. Approximately how much of the total body surface area TBSA did the patient burn?
whole R leg = 18
whole L leg = 18
TBSA = 36%
Prognostic Burn Index
PBI= Age + TBSA (+20% if inhalation injury)
Prognostic Burn Index is used as
crude estimate of mortality and triaging
Associated illness of severe burns
GI complications: pancreatitis, stress ulcers
Associated illness of severe burns may occur
24-48 hours later up to a week
Associated injuries of severe burns
smoke inhalation, electrical burns
What type of burn must you be cautious of?
electrical burn, deep tissue burns without significant superficial trauma, more significant than they appear
50 yo woman presents with a 18% TBSA smoke inhalation burn injury. What is her TBI?
TBI = Age + TBSA + 20% for smoke inhalation
50 + 18 + 20 = 88
ABCDE’s; A/B:
Airway and breathing, intubate to prevent airway edema if inhalation injury or direct thermal injury
ABCDE’s: C
Circulation: establish vascular access with either IV, Intra-osseous, or arterial line for critically ill
What type of antibiotics would you give for non-superficial depth burn wounds?
Topical
2nd degree burn - Deep
red/white, dry, epidermis + most of dermis, no blanching, diminished sensation
A prognostic burn index > ____ has a bad prognosis
50
Burn → inflammatory reactions →
shock (hypovolemic) → multi-organ failure (kidney, heart, lungs)
All burns deeper than superficial thickness, patient should receive
tetanus immunization if not up to date
Regardless of immunization status, all burn patients should receive
Tetanus toxoid-containing vaccine
If patient has unknown tetanus status or does not have 3-steps complete
tetanus immunoglobulin
21 yo homeless woman presents with a 2nd degree burn to her left leg. Patient has no medical records and is intoxicated and cannot provide history. What should you administer to prevent tetanus infection?
tetanus immunoglobulin + Tetanus toxoid-containing vaccine
Escharatomy
dry black, necrotic scab that may impede blood flow if on extremities, may need surgical removal or incision to re-establish BF
