1

3 zones of tissue damage

1. zone of coagulation
2. zone of stasis
3. zone of hyperemia

2

zone of coagulation

point of most damage
irreversible tissue destruction

3

zone of stasis

surrounds zone of coagulation
damage results in decreased perfusion

4

zone of hyperemia

outer zone
tissue at risk but should recover and heal with proper care

5

eschar

residual layers of skin destroyed by direct heat damage

6

superficial burn

only epidermis
redness and pain
dry and does not blister
heals within 3-6 days without scarring

7

partial thickness burn

destroys epidermis and part of dermis
large, thick blisters that increase in size
deep red to waxy white in color
leaks body fluid, moist
heals in 7-20 days with scarring

8

full thickness burn

epidermis and dermis and part of hypodermic layer
usually won't heal by itself
small, thin blisters that won't increase in size
can be black, tan, red, white
dry and leathery in texture
healing depends on donor sites and will leave scarring
severe risk for contractors

9

deep full thickness burn

destroys all layers of skin and extends to bone/muscle
charred or mummified appearance
can result in loss of function
amputation may be needed

10

decreased risks for morbidity/mortality

early excision
skin grafting
antibiotics

11

criteria for burns that should be transferred to a burn center

partial thickness burns of 10% TSBA or higher
chemical burns
electrical burns
burns involving face, genitals, hands, feet, major joints
all full thickness burns
pulmonary/inhalation injury
pt with complicating preexisting medical conditions

12

Burn injuries affect 2 major body systems

pulmonary
cardiac

13

pulmonary complications

carbon monoxide poisoning
upper airway obstruction
restrictive defects

14

cardiac complications

burn shock, burn wound edema, organ failure, tissue hypoxia

15

burn wound management

the acute phase
debridement
grafting

16

the acute phase of treatment

after emergency phase
sepsis is the most common cause of death during this phase
pt vulnerable to infection

17

debridement

cleansing and removal of dead tissue-painful process

18

grafting

skin taken from another part of its body, priority influenced on size of location of burn, hands given priority

19

allograft

donor skin taken from another person

20

autograft

surgical transplantation of patients own skin from one area to another

21

cultured epithelium

biopsy of unburned skin that is sent to a lab to grow skin for grafting

22

phases of rehab activities

emergency phase
acute phase
rehab phase

23

emergency phase

preservation of joint function, ROM exercises, splinting

24

acute phase

reconditioning exercises, ROM exercises, splinting, ambulation and ADL participation

25

rehabilitation phase

reconditioning, ROM, scar revision, contracture release, reconstruction, scar education

26

impact on occupational performance influenced by

size, location, depth of burn

27

greatest potential to impact occupational performance

deep partial thickness burn
full thickness burn
burns involving major joints
larger burn areas

28

RA (Rheumatoid arthritis)

leading cause of disability in the US

29

common symptoms of RA

redness
warmth
swelling/inflammation of joints
general feeling of sickness, fatigue, weight loss
usually affects same joints on both sides of body
may develop suddenly, within weeks, or months
most often begins between ages 25 and 50

30

joint guarding

self bracing, frequent response with RA and JRA due to pain with movement
