Debridment choice Flashcards
(37 cards)
this type of debridement is least painful, all wound types utilize some aspect of it and req. minimal technical skill form PT
However, arterial wounds have difficulty solely depending on this debridement for healing, slow process, & req. multiple dressing changes
Autolytic debridment
what is an absolute contraindication for use of autolytic debridment?
infection
The pro’s of using this debridment tech. is that it selectively tragets + destroys collagen that anchors necrotic tissue with no increase in discomfort for the patient and is faster than autolytic.
However, there is potential for skin maceration and can be deactivated when used with other things (silver, iodine)
enzymatic
list 4 types of mechanical debridment
- soft abrasion (use on epibole)
- wet to dry/moist (NOT recommended)
- hydrotherapy (NOT recommended espec w. CVI or diabetic wounds)
- Low freq. ultrasound
PROs
if need for sterile env and wound is infected
CONs
wounds come back larger and healthy tissue removed as precaution
Surgical debridement
Patients on blood thinners are considered as a precaution when using which debridement technique?
sharp conservative deb.
this type of debridement works by removing necrotic tissue, has antimicrobial activity, and facilitates healing
biological deb.
what are goals of a primary dressing?
prevent adherence
moisture additive/retention
what are goals of secondary dressings?
absorb exudate
provide cushion/protection
prevent drying
skin protectants act as ______ and protect skin from mechanical injury caused by tape and help prevent maceration
moisture barriers
what are contact layers?
barrier b.w wound surface + secondary dressing
T / F Contact barriers allow exudate to pass and protect wound from trauma
T
what wounds would you avoid using contact layers with?
dry wound or wound that needs contact moisture from secondary dressing
3rd degree burns?
Transparent films should not be used on wounds that are _____ or have lots of exudate because this dressing type is only used as prevention from _______ forces on heels.
infected; shear/friction
which dressing promotes autolytic debridement via rehydration?
hydrogels
what wounds would you avoid using hydrogels with?
heavy exudate
macerated periwound
infected wounds
______ provide cushion over bone, maintain moist wound environment, promotes autolytic debridment and can be used under compression wraps
hydrocolloids
Hydrocolloids are not effective on wounds with _____ and should not be used if a wound is _____
dry eschar; infected
this type of dressing wicks away fluid from a wound and can be used if there is mod-heavy exudate and if a wound is infected
foams
precautions when using foam as dressing?
if 3rd degree burn or if there is little exudate present (probably wouldn’t use this)
if patient has dry wound, which dressing would u avoid using?
a. alginates
b. foams
c. contact layers
d. hydrocolloids
e. more than one
f. collagens
a. (fibers react w. exudate and form gel for moisture)
b. used on mod-heavy exudate cause wicks away fluid
c. barrier b.w 2nd dressing that will provide moisture
f. absorbs mod exudate
dry wound: use hydrogels, hydrocolloid, saline soaked gauze
which dressing can you use on infected wounds?
a. hydrocolloid
b. foam
c. alginates
d. transparent film
e. hydrogels
f. more than one
more than one
b. c
this dressing is used as a primary dressing that absorbs exudate and can be used with partial thickness burns, diabetic foot ulcers, and trauma wounds
hydrofibers
this dressing type should not be used with oil based products especially if infused with silver
Hydrofibers
