Flashcards in Burns Deck (22):
1

Scald and Fire injuries, Hot water/grease, smoke inhalation - all examples of what kind of burn

Thermal burns

2

Sunburns are what kind of burn

Radiation

3

Four steps to initial evaluation of burns

1. Airway management
2. Evaluation of other injuries
3. Estimation of burn size (depth and % BSA)
4. Diagnosis of CO and cyanide poisoning

4

Perioral burns and singed nasal hairs are a sign of

direct thermal injury to upper airway (smoke inhalation)

can lead to severe airway edema

low threshold for intubation

5

Hoarse voice, wheezing / stridor indicate

Direct thermal injury to upper airway (smoke inhalation)

can lead to severe airway edema

low threshold for intubation

6

Consider Intubation if:

Suspect airway injury, full thickness burns to face/mouth, circumferential chest burns

7

Continued management of burn patients (after initial evaluation)

1. large bore IVs + fluids ASAP

2. Hypothermia common

3. Tetanus booster

4. TREAT PAIN / ANXIETY

8

Only epidermal layer. Dry, red, painful, blanching. Typically heal in 3-6 days. NO blisters

Superficial / 1st degree

9

Have dermal involvement. Takes 3-8 weeks to heal. Painful! Blisters.

partial-thickness 2nd degree (superficial or deep)

10

Painless, no blanching, do NOT spontaneously heal; Skin grafts

Full-thickness (3rd degree)

11

Life Threatening: may extend into tissue, fascia, muscle bone, organs; multiple surgeries usually required

4th degree

12

Burns typically evolve over _____ hrs after injury

48-72 hrs

13

Superficial vs deep partial thickness burns

Superficial >> epidermis and superficial dermis. 2-3 weeks to heal. No scar.

Deep >> epidermis and deep dermis, sweat glands, hair follicles. Permanent Scar. 3-8 weeks to heal.

14

Decreased sensation, dry leathery eschar, hypoesthesia, and ability to easily pull hairs - suggests what level burn

Full thickness / 3rd degree

15

Burn size estimation "rule of nines"

In adults
anterior and posterior trunk account for 18%

each lower extremity 18%,

each upper extremity 9%,

head 9%.

Hands 1%


**In peds < 3yrs, head = 18% **

16

Superficial or first degree burns - included in rule of nines?

NO

17

Parkland formula for fluid resuscitation in burn tx

LR 4ml x wt (kg) x %BSA = amount given in 24 hours

Half over first 8 hours, half over subsequent 16 hours

18

100 kg male with 20% TSA Burn: how much fluid to give?

4ml * 100 * 20 = 8,000 mL

4 L over first 8 hours, 4 L over 16 hrs

19

how often should burn dressings be changed

twice daily

20

Two important care steps for chemical burns

CAREFULLY remove the substance:

Remove clothes and brush away chemical
Copious irrigation with water

21

Which is worse - alkalis or acids?

Alkalis produce far more tissue damage than acids b/c they penetrate the skin deeper and longer than acids and present a greater danger of toxicity from systemic absorption.

22

partial thickness burns of more than ____% BSA should be referred to burn center

> 10%
