how do alginates/hydrofibers work?

Absorb drainage and convert to a hydrophilic gel

Perfectly

can you presoak alginates/hydrofibers? and how does it work

yes, can soak to bring moisture into the wound soak the dry wound as the body absorbs the dressing starts to dry back up and moisturize the tissue

T/F Hydrocolloid’s have an odor when it is removed

TRUE, have to clean the wound before assessing it for odor

Perfectly

T/F hydrocolloids can work as friction protection

TRUE

What is the mechanism of hydrogels?

preloaded with moisture to maintain moist wound environment

how much drainage can hydrogels handle?

minimal drainage

What type of wounds can you use hydrogels with?

- Re-epithelizing partial thickness wound | - Abrasions, minor burns and other minor wound

T/F hydrogels need cover dressings

TRUE

how much drainage can transparent films handle?

minimal drainage

What is the function of transparent films

maintain moist wound environment

what depth of wounds should you use transparent films for?

superficial wounds

What is another function of transparent films

shear protection (elbows, heels, flat surface)

how do transparent films work?

water proof, but allow for transfer of O2 and water vapor

How do antimicrobial dressings work?

Provide antimicrobial barrier to the wound

what type of wounds do you use antimicrobial dressing for?

For all types of ulcers/wounds

What characteristics cause the antimicrobial-ness (some examples)

Iodine, Silver, Gold, honey

What does antimicrobial dressings control

bioburden

What are 5 things that you can use to Fill a deep and wet wound?

* Calcium alginate * Hydrofiber dressing * Cavity foam * Specialty gauze * NPWT (negative pressure wound therapy)

What are 3 things you can use to Cover and deep and wet wound?

* Gauze * ABD (Army battle dressing) * Foams

What are 3 things that you can use to Fill a deep and dry wound?

* Calcium alginate (moistened) * Hydrofiber (moistened) * Wound gels

What are 4 things you can use to Cover and deep and dry wound?

What are 4 things you can use to Cover and shallow and dry wound?

* Hydrogels * Hydrocolloids * Thin foams * Non-adherent dressing

what 2 types of wounds do you need to support autolysis of necrotic tissue?

Deep and wet, and shallow and wet

Name the best uses for Foams (5)

``` Heavily draining wounds Deep cavity wounds as packing Venous Leg ulcers Padding for foot ulcers Can be used for friction protection ```

What are the best uses for alginates/hydrofibers (5)?

Partial thickness and full thickness wounds Wounds with moderate to heavy drainage Can be used with dressing moistened or dry Needs to have a cover dressing Allow for less frequency of dressing changes

What are the best uses for Hydrocolloid Dressings (4)?

Dressing of granulating and epithelializing partial thickness wounds Wounds with low to moderate drainage Can work as friction protection Not a daily dressing (3-5 days)

What are the best uses for hydrogels (3)?

Re-epithializing partial thickness wounds Abrasions, minor burns and other minor wounds Gels need cover dressing

What are the best uses for transparent films (4)?

Superficial wounds Wounds with minimal drainage Protection for elbow, heels, flat surfaces Covering blisters

What are the best uses for antimicrobial dressings (2)?

For all types of ulcers/wounds | Provide antimicrobial barrier for patients at risk

What are the 5 goals when it comes to picking a dressing for Deep and Wet wound?

``` Fill dead space Absorb exudate Maintain Moist Environment Support autolysis of necrotic tissue Protect and insulate ```

What are the goals for dressing selection of a deep and dry wound (3)?

Fill dead space Maintain moist environment Protect and insulate

What are the goals for dressing selection of a shallow and wet wound (5)?

``` Absorb Exudate Maintain moist environment Support autolysis of necrotic tissue Protect and insulate Protect surrounding skin (need an absorptive cover) ```

What are the goals to picking a dressing for a shallow and dry wound (2)?

Maintain and create moist surface | Protect and insulate
