burns Flashcards
transparent film dressing
- semi-occlusive
- primary or secondary dressing
- reduces infection risk
- creates moist healing environment
hydrogel sheet dressing
- hydrates wound
- keeps bacteria out
- promotes autolytic debridement
alginate dressing
- primary wound care dressing
- can absorb large quantities of exudate
autolytic debridement
- body’s own enzymes break down nonviable tissue
- hydrogel sheet dressing to promote
mechanical debridement
- hydrotherapy
- wet-to-dry dressings
- wound irrigation followed by suction
autograft
transplanting someone’s own skin from unburned area to burned area
split-thickness graft
full epidermal & partial dermal layers & a % of fat layers from donor site
- graft survival is high
full thickness graft
- full thickness of epidermal & dermal layers & % of fat layers from donor site
- graft survival is less
- outcome better if graft adherence occurs
meshed graft
stretched to cover greater surface area
sheet graft
donor graft laid down as is
how is edema measured with a burn?
circumferential measurements (no volumeter)
when is scar management completed after a burn?
6-12 weeks after wound closure
when is the emergent phase of a burn?
0-72 hours after
xenografts
biologic dressing
- bovine skin, processed pig skin to protect skin from infection, debride, comfort during emergent phase
allograft
human cadaver skin
-protect skin from infection, debride, comfort during emergent phase
superficial/epidermal burn
1st degree
- superficial epidermis
- PAIN: min to mod
- BLISTERING: none
- min erytheme (redness)
- HEALING TIME: 3-7 days
superficial partial thickness burn
superficial 2nd degree
- epidermis & dermis
- PAIN: significant
- BLISTERING: wet
- erytheme
- HEALING TIME: 1-3 weeks
deep partial thickness burn
deep 2nd degree
- epidermis, deep dermis, hair follicles, sweat glands
- PAIN: severe, even to light touch
- erythema, with or without blisters
- high risk of turning into full thickness burn due to infection
- consider grafting to prevent infection
- SENSATION: highly impaired
- high potential for hypertropic scar
- HEALING TIME: 3-5 weeks (varies)
full thickness burn
3rd degree
- epidermis, dermis, hair follicles, sweat glands, nerve endings
- PAIN: none
- SENSATION: none, even to light touch
- burn is pale, non blanching
- requires skin graft
- very high potential for hypertrophic scar
subdermal burn
- full thickness burn with damage to underlying tissue (fat, muscle, bone)
- charring, exposed fat, tendons, muscles
- electrical burn = nerve pathway destruction
- significant peripheral nerve damage
- surgical intervention for wound closure or amputation
- extremely high potential for hypertrophic scar
which burn phase includes charring?
subdermal burn
what burn phase has no pain?
full thickness/3rd degree
during what burn phase are skin grafts required?
full thickness/3rd degree
what types of precautions are necessary during the emergent phase of burn?
0-72 hrs after burn
- universal precautions for staff/family
