Integ. Unit 8 Dressing (Part 1) Flashcards
Whats the difference between Primary and Secondary Dressing?
- Primary: This is the first dressing that covers the wound
- Secondary: This consist of all dressings applied over the primary dressing
What are Inert Dressings?
- These are passive dressings, they do no interact with wound
- Their primary role is to absorb exudate as needed and to cover the wound (Simple)
- They are permeable to bacteria and other mico-organisms and are adherent and can cause truama to the wound
(gauze or absorbent pad)
What are Interactive Dressings?
These work with the fluid tissue cells and growth factors within the wound to promote healing
- There are 6 different types
Interactive Dressing
What are Film Dressings?
- These dressings are coated with acrylic adhesive
- They are not absorbent but are permeable to oxygen and air, but impermeable to microorganisms
-
They are flexible, elastic, extendsible and transparent
(So they can adjust to the movement of the body part and we can continue to assess the wound without removing the dressing)
What are the Effects and Indications of using Film Dressings?
- They provide a moist wound environment
- They assist with autolytic debridement
- Provide protection for microorganisms
- Provide gaseous exchange of O2, CO2 and water vapor
-Disadvantage is that they are not very absorbant, so they can promote the accumulation of excessive exudate
Indications:
- Minor Burns
- Simple injuries (abrasions, skin tears)
- Post-op dressing
Interactive Dressing
What are Foam Dressings?
- These are made of polyurethane, soft, open sheets
- They may have 1 or more layers
- Similar in appearance to hydroactive polymer products
- May have a waterproof backing or be impregnated with charcoal
What are the Effects of Foam Dressings?
- Provide moist environment
- Provide high absorbency (for moderate/high exudate)
- Confrom to body shape
- Provide protection and cushioning
- It does NOT adhere to the wound
- Provides thermal insulation
- Transmits moisture vapor out of dressing to avoid maceration
What are the Indications for Foam Dressings?
- When there is Moderate to High Exudating wounds
- Superficial and cavity types of wounds
- LE ulcers, such as venous ulcers
- Pressure injuries
Interactive Dressing
What are Hydrogels?
- This is made up of Complex organic polymers with high water content
- They are 3 dimensional, water swollen structures
2 types:
- Amorphous: Free-flowing, easily fills a cavity space
- Sheet: Thin, flexible sheets that swell as they absorb fluid
What are the Effects of Hydrogels?
- They provide moisture to dry wounds
- They can provide or absorb moisture
- They aid in autolytic debridement
- Conform to body shape
- Does NOT adhere to wound
What are the Indications of using Hydogels?
- Dry and minimally draining wounds
- LE wounds, such as arterial ulcers
- Pressure injuries, Stages 2-4
- Full or partial thickness wounds
- Over tendons and other tissues to prevent tissue dehydration
- Infected and necrotic wounds
Interactive Dressing
What are Hydrocolloids?
- These are dressings that are a combination of gel-forming polymers with adhesives with a backing of a polyurethane film or a foam
- Wound exudate combines with the polymers to create a soft gel in the wound
- Dressing only adheres to surrounding tissues, not the wound itself
What are the effects and indications for Hydrocolloids?
- Provide a moist environment
- Aid in autolytic debridment
- Conform to body shape
- Protect from microorganims
- Provide a waterproof surface
- Not indicated for heavily exudating or deep cavity wounds
Indications:
- Superficial and small cavity wounds
- LE wounds, burns, pressure injuries
Interactive Dressing
What are Alginates?
- These are made of calcium or calcium/sodium salts of alginic acids from seaweed
- Available as textile fiber sheets or a loose packing ribbon
- Produce a hydrophilic gel in the wounds
- Provide calcium ions to the wound to promote hemostasis
What are the effects of Alginate dressings?
- Provide a moist environment
- High absroptive capacity
- Conform to body shape
- Protect from microbial contamination
- Promotes hemostasis
- Does not adhere to wound
What are the indications to use Alginates?
- With Heavily exudating wounds, including sanguinous exudate
- Infected wounds
- Cavity wounds
- LE wounds
- Pressure injuries
- Donor sites
Interactive Dressing
What are Hydroactive Dressings?
- These are multiple layers of highly absorbent polymer gel with adhesive backing
- Similar to hydrocolloidsm, but do not form gel in wound
- Semipermeable
- Adhere to surrounding skin
- Available in various forms, including cavity fillers, foams, and thin types
What are the effects of Hydroactive Dressings?
- Provide moist enviornment
- Aid in autolytic debridement
- High absorbency
- Waterproof surface
- Regain their shape when stretched
- Semipermable to water vapor
What are the Indications for using Hydroactive Dressings?
- Moderate to heavily exudating wounds
- LE ulcers, such as venous ulcers
- Pressure injuries
- Wound around joints
What do Collagen Matrix Dressings do?
- Contain collagen that stimulate fibroblast activity
What do Hydrofiber dressings do?
- These are activated by moisture, plymers absorb and trap moisture in their structures
-Look like alginates
What do Silicones do?
- These are used on the surface layer to help maintain adhesion of the dressing to the skin without actually sticking to the wound or skin to reduce trauma during removal
- Found on foams, and other types of dressings
