Wound Care Exam II Flashcards
Standard Care and Tratments
- debridement
- cleansing
- dressings
- compression
- antibiotics
- pressure redistribution
Cleansing
syringe vs. gauze
- saline
- betadine
- hydrogen peroxice
- dakin’s solution
- acetic acid
saline
normal body fluid
can use on all wounds
especially good for healthy, well healing wounds
Betadine
- cytotoxic
- for infection and exudate control
- gangrene
- drying effect, good for drainage
Hydrogen peroxide
- cytotoxic
- use within first 48 hours
- only used for infection or inflammation
Dakin’s solution
- cytotoxic
- infection and oder
- bleach
Acetic Acid
- cytotoxic
- infection
- psuedomonas
- vinegar
Mild and gentle cleaning if…
granulation tissue
Aggressive cleaning if…
eschar, slough, infection, biofilm
Match the dressings to the wound
- if it’s wet, absorb it
- if it’s dry, moisten it
- if its a hole, fill it
- if its dirty, clean it
- if its clean, protect it
Tissue load management
- pressure re-distribution
- move pressure from high risk areas to low risk
- bed based pressure reducing surfaces
- seating surfaces
- off loading gait
Foam
- usually the first line of defense
- least expensive
- disadvantages include moisture retention and heat retention
- not good for pts who are incontinent or obese
Fluid-filled surfaces
- high degree of immersion
- air, gel, water
- may retain heat, depending on type of fluid
- better for obese patients
Low-air-loss systems
- connected, air filled cushions, served by an air pump
- many have automatic adjustment to the pt’s body weight distribution
- immersion is moderate
Air-fluidization
-micro-fine silicon beads in a box, covered with a loose sheeting material while warmed air is forced through the beads
-beads take on fluid characteristics
-similar to fluidotherapy
-watch for dehydration
-high level of immersion
-GOLD STANDARD for pressure re-distribution
-expensive
“clinitrons”
Alternating pressure
- air filled chambers with a pump that inflates 1-3-5-7-9 while 2-4-6-8-10 deflate, then reverse cyclically
- changes the bed to body contact points
- not immersion
Other tissue load management ideas
- no surface takes away from the need for good care and turning every 2 hours
- multiple features available
- W/C fitting can be complex
Heel load management
- special attention for heels, due to incidence of breakdown
- poorly vascularized
- gold standard is to float the heels
- pillows
- orthotic heel boots
Pressure mapping
- system used to identify areas of increased pressure or WB
- can be used in any setting
- need patient to act as though they do at home in their environment (ex. let pt ride in wheelchair for a while and get comfortable before assessing, then look at load distribution, then have them show you how they “off load”)
Advantages of pressure mapping
- individualized and specific
- IDs mild to high risk for pressure ulcers
- locates specific areas at risk for breakdown
- allows for adjustment or ordering of equipment to improve pressure
- educates patients and family about positioning for pressure relief
Patients/clients who benefit from pressure mapping
- people with hx of skin breakdown or pressure ulcers that have adaptive equipment or seating
- people working with DME company assessing for needs
- anyone with current pressure ulcer
Pressure mapping positions
- posture
- leaning (sides, forward, back)
- push ups
- glut sets
- reclining and tilting
- equipment adjustments–foot rests, lumbar rolls, air pressure in cushion
Appropriate referrals
- people who have some sort of seating system and risk factors for skin breakdown or ulcers
- people who qualify for new equipment or seating
- previous people who would benefit from additional education and visual aids
Braden scale examines
- sensory perception
- moisture
- activity
- mobility
- nutrition
- friction and shear
Braden scale scoring
15-16=mild risk
12-14=moderate risk
less than 12=high risk
Skin care education
- bathe daily or every other day with skin inspection
- moisturize daily-no fragrances
- do not rub or massage over bony prominences
- encourage smoking cessation
- positioning/mobility training
- check for moisture and reposition every 2 hours
- clean any incontinece immediately
Re-certifation
- every 4 weeks
- should be re-assessing and revising informally every 2-4 weeks
Palliative care
- focus shifts to wound management
- also focus on protection from infection (possibly by use of occlusive dressings or topical antimicrobials)
- odor control
- pain control
- pt and caregiver training
Methods of selective debridement
- sharp
- autolytic
- enzymatic
- biologic
Methods of non-selective debridement
- mechanical
- surgical
Sharps debridement
- removal of necrotic tissue by use of sharp instruments (forceps, scissors, scalpel)
- selective
- aggressive
- may be painful
Sharps debridement not appropriate for…
- pts with insufficient vascular supply or nutrition
- precuation if on blood thinners
Role of debridement (stats)
- important to do it within the 1st 4 weeks
- if done within 1st 4 weeks, 54% higher wound reduction
Termination of sharps debridement
- clinician fatigues
- pain is not adequately controlled for patient
- decline in patient status or tolerance
- extensive bleeding
- new fascial plane identified
- nothing remaining to debride
Autolytic debridement
- natural degradation of devitalized tissues with enzymes or moisture
- conservative
- little pain
- slow method
- not appropriate with infection or arterial insufficiency
Enzymatic debridement
- use of enzymatic ointments to loosen and remove devitalized tissues and proteins
- papain-urea
- colagenase
- sometimes slow
- nonselective
- may be painful
Termination of enzymatic debridement
- once satisfactory debridement has occurred
- if necrotic tissue fails to decrease in expected amt of time
Procedure for enzymatic debridement
- follow manufacturer’s guidelines
- physician’s prescription
- eschar to be crosshatched prior to application
- moist environment
- observe for S/S of infection
- prophylactic topical antimicrobial therapy prn
Biological debridement
“larva therapy”
- sterile-lab raised maggots
- definitely requires a secondary dressing
- very selective
- can help to reduce bacterial counts
- of limited application, partially due to the squeamish factor
How biologic debridement works
- larvae release enzymes that degrade/liquefy necrotic tissue
- larvae ingest necrotic tissue and bacteria
- literature supports use for pressure and neuropathic ulcers, traumatic wounds and chronic leg ulcers
Mechanical debridement
- use of external forces to non-selectively remove necrotic tissue
- painful
- non-selective
- can cause bleeding and trauma to wound reducing new cells
- wet to dry
- gauze
- whirlpool
- pulsed lavage
Surgical debridement
- use of scalpels, scissors, lasers in sterile environment
- performed by physician or podiatrist
- allows for extensive exploration of wounds bed and debridement of deeper structures
Indications for surgical debridement
- ascending cellulitis, osteomyelitis, extensive necrotic wounds, undermining
- necrotic tissue near vital organs/structures
Contraindications to surgical debridement
-patients who are unlikely to survive procedure or patients with palliative care plans
Surgical debridement procedure
- shaving of eschar with dermatome
- incision and drainage (i and D)
- possible tissue biopsy
- followed by appropriate antimicrobial therapy
Goals in wound healing debridement
- promote wound cleansing to remove debris and necrosis
- reduce bacterial bioburden and reduce risk of infection
- promote optimal environment for wound healing
- promote inflammation to facilitate angiogenesis
Considerations for debridement
- characteristics of wound
- status of patient
- existing practice acts
- clinican’s knowledge and skill level
Documentation for debridement
- must have specific physician’s orders
- selective vs. non-selective
- distinguish conservative sharps debridement
- location, type, and amount of necrotic tissue present
- type and amount of necrotic tissue removed
- instruments used and settings used if applicable
- CPT codes
Contraindications for debridement
- dry gangrene
- eschar that is intact, without drainage, erythema or fluctuance on a patient with poor circulation
- unidentified structures in wound bed
Steps to prepare patient for debridement
- assemble equipment
- Position patient comfortably
- use proper posture and body mechanics to allow safe techniques and minimize fatigue
- ensure sufficient lighting
- wash hands and don gloves
- remove old bandage and discard
- discard gloves and put new ones on
- inspect wound
- remove gloves
- explain to pt
- don gloves and initiate debridement
Whirlpool benefits
- cleanses wound
- promotes circulation
- promotes debridement
whirlpool precautions
- malignancy in area
- promotes edema
- trauma to healthy tissue
- may promote maceration
- avoid in diabetic wound (because they will macerate)
non-thermal temp
better if patient has edema and you are just trying to cleanse the wound
Whirlpool precautions/contraindications
Wounds that are-
- clean, macerating, actively bleeding (profuse)
- tunneling, undermining
- arterial insufficient wounds (use low temp)
- > 50% clean wound
- moderate-severe edema (venous insufficiency)
- incontinent, confused or combative pt
Whirlpool risks
- infection (contaminated water, cross contimination)
- superhydration/maceration
- changing of skin pH
Hydrotherapy considerations
Water temp
- non thermal (80-92 F)
- neutral (92-96)
- thermal (96-104)
- patient position (dependency promotes edema)
- duration of treatment
- additives/chemicals
Chemical additives
- clinicians must weigh potential benefits of antimicrobial application with known risks of delayed wound healing
- should not be used on chemical wounds
- contraindicated in young, elderly, and those who are sensitive to those agents
- use is not recommended except in isolated patients
Hydrotherapy decision making
- positioning
- temp
- time
- agitation
- contamination
- clean up
Pulsatile lavage
- promotes localized circulation
- reduces bacterial load
- healthy debridement if using high pressure jet system
- 5-15 psi
- must wear protective clothing
Pulsatile lavage with suction
- reliable, focused alternative to whirlpool for wound cleansing
- minimal risk of cross-contamination
- eliminates dependent edema issues
- less time involved for more focused cleansing
- patient specific supplies
- see your PT team member
Wound irrigation
- syringe vs. gauze
