PTA Acute Care - Dressings (wound interventions) Flashcards
describe Hydrocolloids:
- adhesive around the outside of the dressing
- doe not adhere to actual wound
- exudate absorbed into gel (kinda like a diaper)
what is the Hydrogel dressing?
a sheet for super and partial - minimal drainage -not much drainage
just lays on top of wound
describe Foam dressing:
- “moisture loving” (hydrophilic) polyurethane base which touches wound
- “moisture repelling” (hydrophobic) outer later
- absorb exudate into foam through hydrophilic layer
describe Transparent Film dressing:
- like a second skin
might be on an IV wound - Thin membranes of transparent polyurethane with water-resistant adhesives
- Permeable to vapors and oxygen
- Impermeable to water and bacteria
- Elastic and conform easily
discuss a little about Gauze:
the other card is in the other deck
dry by itself is pointless but readily available
- can modify the number of layers
- does do a bit of debridement upon removal (wet-to-dry)
cheap, but not necessarily cost effective because maybe change too much
- disadv - adhere too much, highly permeable, increase infection rate
describe Alginate dressing:
- made from seaweed - highly highly absorbant
- highly permeable
- requires second dressing
- for wound with lots of exduate
- partial or full thickness wounds
- will leave a greenish tint but not terrible odor
How does a wound heal?
from the bottom up
types of wound
arterial
venous
pressure ulcers (bony prominence causes skin breakdown)
diabet
promote healing
Nutrition!! - cannot heal well without nutrients good bandage! blood supply moisture pressure relief debridement
debridement
mechanical
enzymatic - extra product for breakdown
autolytic - body does the breaking down
sharps
mrsa
has a distinct smell
spider bites susceptible to MRSA
MRSA still so dangerous
family support
yep
wound VAC on infected wound?
NO
PT on burn
positioning - to extension
care of skin graft - ROM
do ROM for avoid Heterotrophic Ossification
discuss Indications, Pros and Cons of Hydrocolloid dressing:
Indication
- for any wound with drainage
- partial and full-thickness wounds (granular or necrotic)
Pro
- absorb drainage
- waterproof on the outside
- Provides moist environment
- Enables autolytic debridement
- Protects for contamination
- Moderate absorption
- No secondary dressing
Con
- can macerate the surrounding skin upon removal
- necrotic yes/infected No
- rolls in areas of excessive friction
discuss Indications, Pros and Cons of Hydrogel dressing:
Indications:
- Gels are moisture retentive
- Typically used on superficial and partial-thickness wounds that have minimal drainage
Pros:
- Moist environment
- Enables autolytic debridement
- Reduce pressure and diminish pain
- Used as coupling agent for ultrasound
- Minimally adheres to wound
Cons:
- Potential for dressing to dehydrate
- Can not be used on wounds with lots of drainage
- Needs secondary dressing
discuss Indications, Pros and Cons of Foam dressing:
Indications:
- Partial and full-thickness wounds with exudate
- Can be used over hydrogels
Pros:
- Moist environment
- Prophylactic protection and cushioning
- Autolytic debridement
- Moderate absorption
Cons:
- Roll in areas of friction
- Adhesive causes trauma to peri-wound with removal
- Inspection of wound difficult
discuss Indications, Pros and Cons of Transparent Film dressing:
Indications:
- Superficial or partial-thickness wounds with minimal drainage (abrasions)
Pros:
- Moist environment
- Autolytic debridement
- allows visual inspection of wound
- Resistant to shear/ frictional forces
- Cost effective
Cons:
- Excessive exudate can accumulate in wound
- Adhesive trauma to wound when removed (pull away skin upon removal)
- Can not be used on infected wounds
discuss Indications, Pros and Cons of Alginate dressing:
Indications:
- Partial or full-thickness drainage wounds
- Used on infected wounds
Pros:
- Highly absorptive
- Autolytic debridement
- Protection from microbes
- Used on infected or non-infected wound
- Non adhering to wound - just breaks down
Cons:
- May require frequent dressing changes
- Requires secondary dressing
- Cannot be used on wounds with exposed bone, tendon, or joint capsule (will react with calcium in the bone)
