Wound Debridement's - Class 3 Flashcards
clinical decision making
know the pts history
what are the goals of care
what is the clinical presentation of the wound?
goals of care
to achieve full closure
to prepare for surgical closure
to manage wound deterioration
to maintain a stable non healing ulcer
clinical presentation of the wound
helps identify treatment objects
granulating/epithelializing
protect and keep moist
necrotic
debride it
infected
antiseptic/antibiotics/debride
heavily draining
absorb it
desiccated
moisten it
odorous
charcoal based
antiseptics
undermined/tunneled
lightly pack wound
bone/tendon exposure
protect and keep moist
xeroform
flap/graft exposure
protect and keep moist
xeroform
organ/mesh exposure
protect and keep moist (xeroform)
wound bed preparation
debridement
dressing selection
types of wound debridement
surgical
sharp
mechanical
enzymatic
autolytic
biosurgical
surgical debridement is only performed by
physicians
podiatrists
certified PAs
surgical debridement includes
removal of both viable and nonviable tissue
w/ sterile, sharp instruments
surgical debridement is
quick
but non-selective form of debridement
when is surgical debridement done
when wide excision into viable tissue is required
when removal of necrotic or infected bone is necessary
where is surgical debridement done
bedside or OR
surgical debridement is likely to be
very painful
so premedication is required
sharp debridement can be performed by
PTs, PAs, some nurses
who is not allowed to do sharps debridement
PTAs
sharp debridement is
removal of non viable tissue
only w/ sterile instruments
sharp debridement is a ____ form of debridement
quick and selective form
sharp debridement can be
very painful
sharp debridement has an
increased risk for infection
sharp debridement requires
skill
comfort form clinician
indications for sharps debridement
extensive necrotic tissue
advancing cellulitis or sepsis
thick adherent eschar
as adjunct to other therapies
callous formation
contraindications for sharp debridement
arterial insufficiency (ABI < 0.5)
gangrene
stable heel ulcers
unidentifiable structures
terminally ill
key to comfort in debridement
knowing your anatomy
recognizing what is normal
viable fat is
shiny and yellow
nonviable fat is
dull gray/brown to black
viable fascia is
glistening white
nonviable fascia
dull gray/brown to black
muscle viable
dull red
contractile if pinched
nonviable muscle
dark red/brown –> gray
viable bone
shiny and white
periosteum intact
nonviable bone
dull and yellow –> brown/black
vessels viable
shiny white and pulsatile
reasons to stop sharps debridement
clinician/pt fatigue
bleeding
pain
to viable tissue
location of fascial plane
location of named structure
high anxiety level
achieved set limit time
how to stop bleeding
pressure x 10 min
elevation
calcium alginate
xylocaine jelly-vasoconstrictor
nitrate sticks-cauterizes tissue
bleeding to fear
those that you can hear
those that you can’t see
mechanical debridement
scrubbing
wet to dry dressing
hydrotherapy/whirlpool
forced irrigations/pulsed lavage
scrubbing
non selective form of debridement
use gauze
wet to dry dressing
non selective form of debridement
dessicates wound bed
what can wet to dry dressings be used on
necrotic wounds (<30% granulation tissue)
infected wounds
hydrotherapy/whirlpool
non selective form of debridement
softens adherent necrotic eschar and slough for easier sharp debridement
to clean dirt –> hydrotherapy
foreign materials or residues from topical agents in the wound
what does hydrotherapy aid with
removal of dressing with burn wounds
systemic effects of hydrotherapy
increased HR and RR
sedation, analgesia, muscle relaxation
changes in thermoregulatory system
forced irrigation/pulsed lavage
non selective form of debridement
costly
painful
labor friendly compared to whirl pool
enzymatic debridement
selective form of debridement
enzymatic debridement is
slower than surgical/sharp
less traumatic for the wound and pt
what does enzymatic use
topical enzymatic debriding agents to liquefy devitalized or necrotic tissue
topical enzymatic debridement agents
heavy metals
silver dressings
collagenase santyl
(inactivates enzymatic properties)
autolytic debridement
most selective form of debridement
what does autolytic debridement use
moisture retentive dressings to the wound
body’s own macrophage, neutrophil and other phagocytic cells to digest necrotic tissue
autolytic debridement is
relatively painless
autolytic debridement requires
the least skill in performing
autolytic debridement should not be used
on grossly infected wounds
biosurgical debridement other names
maggot debridement therapy (MDT)
larval therapy
biodebridement or
biosurgery
MDT uses
live maggots
“green bottle fly”
MDT is a
selective form of debridement
how is MDT a surgical form of debridement
clean wounds by dissolving dead and infected tissue
disinfect wounds by killing bacteria
promote growth of fibroblasts
