1

Burn Causes include:

-thermal
-chemical
-electrical
-radiation

2

burns are ____ injuries

-multi-system

-especially if burn is greater than 25% TBSA

3

TBSA

total body surface area

4

thickness of burn determines_____

-extent of tissue damage

5

Hypertrophic scarring can result from_____

-partial- and full- thickness burns

6

Burn Classifications

-superficial partial thickness
-deep partial thickness
-full thickness

7

Sunburns are a type of ____

1st degree burn

8

Superficial Partial Thickness

-epidermis and dermal papillae (can involve some of basal cell layer)
-2-3 weeks to heal (re-epithelialization)
-no scar

9

Superficial Partial Thickness S/Sx

-erythema
-wet
-shiny
-surface
-edema
-painful

10

Deep Partial Thickness

-significcant damage to dermis
-3-4 weeks for healing with scar tissues (may hypertrophy and contract)
-may need skin graft

11

Deep Partial Thickness S/Sx

-erythema
-blisters
-white
-waxy
-pliable
-pain to deep pressure
-cold
-may be insensitive to light touch

12

Full Thickness

-epidermis and dermis destroyes
-possible subq also
-skin graft to heal
-scar may hypertrophy and contract

13

Full Thickness S/Sx

-brown/black, deep red, white
-dry surface
-edema
-painless
-insensate

14

Rule of Nines

-assessment of burn size
-arms/head=9% each
-Legs, ant/post trunk=18% each
-genitals=1%

15

Rules of Nines for Kids

-head=12%
-trunk ant/post=18%
-arms=9%
-Legs=16.5
-genitals=1%

16

Burn Impairments

-shift of body fluids to interstitial spaces
-loss of tissue
-loss elasticity
-scar hypertrophy
-scar contraction

17

Capillary walls during injury

-more permeable
-fluid flows out of vessels to interstitial space
-take in nutrients, WBC and oxygen to injured area

18

Burn Intervention

-Airway & Breathing
-Fluid Resuscitation
-Escharotomy
-Fasciotomy
-Nutrition
-Pain management
-wound management

19

Escharotomy

-release of scar tissue

20

Fasciotomy

-release of fascia

21

Burn Surgical Management

-skin graft
-muscle flap

22

Skin Graft

-full thickness burns require (unless very small)
-large area burns require graft (regardless of depth)

23

Graft Site

-location of burn that will be covered by homograft or autograft

24

Donor Site

-area that contributes the skin in autograft

25

Autograft

-from another part of same body

26

Allograft

-graft from same species (cadaver or other person)

27

Heterograft

-(zenograft)
-from another species (pigskin)

28

CEA

-Cultured Epithelial Autograft
-skin of pt grown in lab

29

Integra, Apligraf, dermagraft

-dermal replacements

30

Sheet Graft

-more cosmetically appealing
-requires larger donor site
-always used on face and hands
