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
