S1L1: Wound Management Flashcards
T/F: Cleansing method should be selected on its ability to support or return a wound bed to homeostasis
True
T/F: Whirlpool is a cleansing agent only
False: Both a cleansing agent and mechanical
debridement
T/F: Whirlpool use selective mechanical debridement
False: non-selective
T/F: In whirlpool, there is Large risk of contamination of wound
True
● Basically, it is a cleansing tool which uses suction to clear out well the debris from the irrigation process
● AKA Forceful irrigation
PULSATILE LAVAGE WITH SUCTION
Potential risk of PULSATILE LAVAGE WITH SUCTION
Overuse
If you over debride the wound you will risk the
removal of the viable tissues that the wound needs
to be able to heal
● Wound Irrigation + suction to clean out wound exudate &
debris, & delivers medication
● May aerosolize microorganisms
PULSATILE LAVAGE WITH SUCTION
● Pouring a solution over a wound using a bulb syringe or other device
Non-forceful irrigation
● Mostly used to treat wounds that are clean, & only need removal of endogenous fluids, or residue by cleaning products
NON-FORCEFUL IRRIGATION
● Topical solutions that are marketed for acute & chronic wounds
● Most have some antimicrobial effects but most have significant antimitotic effects
COMMERCIAL SKIN & WOUND CLEANSERS
Refers to the
● The removal of foreign matter & dead or damaged tissue
● More of a mechanical means
Wound debridement
● Removal of all types of tissue
● Quick, but painful & damages nearby tissue
● E.g. whirlpool
NONSELECTIVE DEBRIDEMENT
● Removes necrotic tissue in a controlled manner
● More comfortable & gentle
SELECTIVE DEBRIDEMENT
Application of a wet dressing that is allowed to dry on the wound
Wet to Dry Dressing
Wet to Dry dressing: Selective or Non selective?
Nonselective
● Rapid results for treating life-threatening necrosis, large wounds, tunneling wounds, & necrotic or infected bone
SURGICAL DEBRIDEMENT
● Nonselective debridement with cleansing
PULSATILE LAVAGE WITH SUCTION
● Through the use of agitation
● Can soften necrotic tissue prior to other forms of debridement
WHIRLPOOL
Gold standard of wound debridement
SHARP DEBRIDEMENT
Removal of dead, necrotic tissue with the use of a scalpel, scissors, or forceps (sterile)
SHARP DEBRIDEMENT
T/F: Sharp debridement is Contraindicated for vascular wounds with limited blood flow where the eschar may be covering a chronic open wound
True
Because eschar aids in healing of wounds
T/F: Sharp debridement is not appropriate for tunneling
true
Application of a topical agent using enzymes that act by dissolving necrotic tissue
CHEMICAL OR ENZYMATIC DEBRIDEMENT
T/F: Chemical or Enzymatic debridement is nonselective, discomfort is minimum, simple application procedure
False: Selective, discomfort is minimum, simple application procedure
T/F: in chemical/enzymatic debridement, there is a Potential development of dermatitis, frequent dressing changes disrupts wound bed
True
T/F: CHEMICAL OR ENZYMATIC DEBRIDEMENT is antimicrobial
False: Not antimicrobial.
Thus, can remove necrotic tissue but does not remove bacteria present in the area
Clean maggots are put in the wound and they are the
ones that are eating out the slough, eschar and other bad
tissues but leaving viable tissue to heal after
Maggot debridement therapy (Biosurgery)
Recommended for osteomyelitis & deep wound
infections that remain unresponsive to regular therapy
Maggot debridement therapy (Biosurgery)
Topical Agents: Antiseptic vs. Antibacterials
Povidone-Iodine
Antiseptic
Topical Agents: Antiseptic vs. Antibacterials
Gentamycin/Geramycin: currently effective against
all species of staphylococcus and streptococcus.
Antibacterial
Topical Agents: Antiseptic vs. Antibacterials
Bactroban/Mupirocin: currently effective against all
species of staphylococcus.
Antibacterial
Topical Agents: Antiseptic vs. Antibacterials
Sulfamylon/Mafenide acetate: diffuses easily
through eschar, primarily for thermal injuries.
Antibacterial
Topical Agents: Antiseptic vs. Antibacterials
Furacin/Nitrofurazone: cytotoxic in animal studies.
Antibacterial
Topical Agents: Antiseptic vs. Antibacterials
Silvadene/Silver Sulfadiazine: primarily for thermal
injuries, silver is selectively toxic to bacteria but may
inactivate topical proteolytic enzymes.
Antibacterial
Topical Agents: Antiseptic vs. Antibacterials
Bacitracin/Baciguent: associated with allergic
reactions
Antibacterial
Topical Agents: Antiseptic vs. Antibacterials
Hydrogen Peroxide
Antiseptic
Topical Agents: Antiseptic vs. Antibacterials
Acetic Acid Solution
Antiseptic
Topical Agents: Antiseptic vs. Antibacterials
Sodium Hypochlorite Solutions = bleach solution,
contains antimicrobial properties
Antiseptic
● Stimulates cellular activity, accelerates inflammation
● Skin repair & wound contraction
● Strengthens scar tissue
● Cover the wound with a sheet of hydrogel
ULTRASOUND
● Acute & chronic wounds
● Eliminate bacterial load, promote granulation, decrease
inflammation, reduce wound related pain, augment blood
flow
ELECTRICAL STIMULATION
ES: Applied using a soaked gauze or a hydrogel dressing, direct or indirect?
Direct
ES: Periwound area, direct or indirect?
Indirect
T/F: Thermal & Nontheemal diathermy is Not indicated for patients with arterial insufficiency
True
Increase fibroblast proliferation, collagen formation,
tissue perfusion, & metabolic rate
THERMAL & NON-THERMAL DIATHERMY
