- healing time: 3-7 days
5
Q
Superficial partial thickness/superficial 2nd degree burn
A
- involves epidermis & upper dermis layers
- pain: significant, wet blistering, erythema present
- healing time: 1-3 week
6
Q
Deep partial thickness/deep 2nd degree burns
A
- involves epidermis, deep dermis, hair follicles, sweat glands
- pain: severe even to light touch
- erythema present w/without blisters
- burn has high risk of turning into full-thickness burn because of infection; consider grafting to prevent infection
- may have impaired sensation
- high potential for hypertrophic scar
- healing time varies from 3-5 weeks
7
Q
Full thickness/3rd degree burn
A
- involves epidermis, dermis, hair follicles, sweat glands, nerve endings

A
- full-thickness burn with damage to underlying tissue (fat, muscles, bone)
- charring present; may have exposed fat, tendons, muscles
- if burn is electrical: destruction of nerve along pathway is present
- peripheral nerve damage is significant
- requires surgical intervention for wound closure or amputation
- extremely high potential for hypertrophic scar
9
Q
Mechanisms of burns
A

11
Q
Which is more severe: alkali or acid burn
A
Alkali
12
Q
Which is more dangerous: high voltage or low voltage electrical burn?

13
Q
Causes single muscle contraction & throws victim from the source, client more likely to have blunt trauma along with burn
A
High voltage direct current
14
Q

Rapid leakage of IV fluid into surrounding extra vascular tissues = decreased plasma & blood volume, reduced cardiac output
18
Q
When is cardiopulmonary stability important?
A
If respiratory tract has sustained smoke inhalation injury
19
Q
What leads to compartment syndrome?

26
Phase occurring 72 hours after injury or until wound is closed (days or months)
Acute phase
27
Acute phase focuses on
Infection control, grafts, biological dressings, psychological support & team communication
28
Surgical intervention during acute phase
1. Escharotomy & debridgement
- removal of burned/dead skin to allow new vascularized skin to close up wound
29
Autograft
Transplantation of person’s own skin from unburned donor suite to burned receiving site
30
Split-thickness skin graft
- full epidermal & partial dermal layer taken from donor site
- change of graft survival is high
31
Full-thickness skin graft
- full thickness of epidermal & dermal layers + % of fat layers taken from donor site
- chance of graft survival less
- outcome functionally/cosmetically better if graft adherence occurs
32
Meshed versus sheet graft
- meshed: donor graft is “meshed” & stretched to cover greater area of receiving area
- sheet: donor graft removed & laid down on receiving area as is
33
Rehabilitation phase
- skin grafts
- reconstruction surgery as needed for movement/function
34
During emergent phase, what is the splinting protocol?
Antideformity positions

42
How to avoid pooling of fluid/blood in LEs in dependent or standing position during acute phase
Apply compression wrapping to provide vascular support to LEs before walking, standing, prolonged sitting w/feet in dependent position
43
Immobilization period in postop phase
- generally 3-10 days or until graft adherence is conformed
- immobilization of donor site: 2-3 days if no active bleeding occurs
- walking not resumed until 5-7 days for LEs
- confirm with surgeon
44
Positioning during postop phase
Same as anticontracture positioning
- promote greatest SA for graft placement
- surgeon may specify
- elevation, wrapping with elastic bandage at donor site
45
Exercise & activity during postop phase
- should be continued for uninvolved extremities
- after immobilization period, start with gentle AROM to avoid shearing of new grafts
46
What occurs during rehabilitation phase
Wound is healing, wound closure is stable
47
Skin conditioning during rehabilitation phase
