Cards

Term
Clear, adhesive, semipermeable membrane dressings. Permeable to atmostpheric oxygen and moisture vapor yet impermeable to water, bacteria, and environmental contaminants
Definition
Transparent (thin) films
Term
Adhesive wafers containing hydroactive/absorptive particles that interact with wound fluid to form a gelatinous mass over the wound bed. May be either occlusive or semi-occlusive. Available in paste form that can be used as a filler for shallow cavity wounds
Definition
Hydrocolloids
Term
Water and glycerin-based gels. Insoluble in water. Available in solid sheets, amorphous gels, or impregnated gauze. Absorptive capacity varies.
Definition
Hydrogels
Term
Semipermeable membranes that are either hydrophilic or hydrophobic. Vary in thickness, absorptive capactiy, and adhesive properties
Definition
Foams
Term
Soft, absorbent, nonwoven dressings derived from seaweed that have a fluffy cotton-like appearance. React with wound exudate to form a viscous hydrophilic gel mass over the wound area. Available in ropes and pads
Definition
Alginates
Term
Made of cotton or synthetic fabris that is absorptive and permeable to water and oxygen. May be used wet, moist, dry, or impregnated with petrolatum, antiseptics, or other agents. Com in varying weaves and with different size interstices.
Definition
Gauze dressings

Term
What are some indications for gauze dressings?
Definition
-Exudative wounds
-Wounds with dead space, tunneling, or sinus tracts
-Wounds with combo exudate and necrotic tissue
Term
What is an indication for using a wet-to-dry dressing
Definition
Mechanical debridement of necrotic tissue and slough
Term
What is an indication for a continous dry dressing
Definition
Heavily exudating wounds
Term
What is an indication for a continous moist gauze dressing?
Definition
-Protection of clean wounds
-Autolytic debridement of slough or eschar
-Delivery of topical needs
Term
What are some advantages of thin films?
Definition
-Visual eval of wound without removal
-Impermeable to external fluids and bacterial
-Transparent and comfy
-Promotes autolytic debridement
-Minimizes friction
Term
What are the advantages of hydrocolloids?
Definition
-Maintain moist environment
-Nonadhesive to healing tissue & comfy
-Impermeable to external bacteria and contaminants
-Support autolytic debridement
-Minimal to mod absorption
-Waterproof, reduce pain, easy to apply
-Time-saving, diminish friction
Term
What are some advantages of hydrogels?
Definition
-Soothing, cooling, fill dead space
-Rehydrate dry wound beds
-promotes autolytic debridement
-Provide minimal to mod abroption
-Conform to wound bed
-Transparent to translucent
-many are non-adherent
-Amorphous form can be used when infection is present
Term
What are the advantages of foams?
Definition
- Insulate wounds
- Provide some padding
- Most are non-adherent and comfy
- Easy to use; manage light-mod exudate
- Some are designed for deep cavities
Term
What are some advantages of alginates?
Definition
-Easy to apply
-Absorb up to 20X their weight in drainage
-Fill dead space
- Supports debridement in presence of exudate
Term
What are some advantages of gauze dressings?
Definition
-Readily available, cheap
-can be used with solutions such as gels, normal saline, or topical antimicrobials to keep wounds moist
-can be used for infected wounds
-Good mechanical debridement if properly used
-Cost-effective filler for large wounds
-Effective delivery of topicals if kept moist
Term
What are some disadvantages of thin films?
Definition
-Nonabsorptive
-Application can be difficult
-Channeling or wrinkling occurs
-Not to be used on wounds with fragile surrounding skin or infected wounds
Term
What are some disadvantages of hydrocolloids?
Definition
-Non-tranparent
-May soften and change shape with heat or friction
-Odor and yellow drainage on removal
-Not recommended for wounds with heavy exudate, sinus tracts, or infections; wounds that expose bone or tendons; or wounds with fragile surrounding skin
-Dressing edges may curl
Term
What are some disadvantages of Hydrogels?
Definition
-Most req a secondary dressing
-Not used for heavy exudate
-May dry out then adhere to wound bed
-May macerate surrounding skin
Term
What are some disadvantages of foams?
Definition
-Nontransparent
-Non-adherent foams require secondary dressing, tape, or net to hold in place
-Some newer foams have tape on edges
-Poor comformability to deep wounds
-Not for use with dry eschar or wounds with no exudate
Term
What are some disadvantages for alginates?
Definition
-Require secondary dressing
-Not recommended for dry to light exudate
-Can dry out wound bed
Term
What are some disadvantages for gauze dressings?
Definition
-Delayed healing if used improperly
-Pain on removal (wet to dry)
-Labor-intensive
-Require secondary dressing
Term
Name 5 considerations for using thin films
Definition
1. Allow 1-2 inch wound margin around wound bed
2. Shave surrounding hair
3. Dressing change varies with wound condition and location
4. Secondary dressing not req
5. Avoid infected wounds, lots of drainage, or tracts
Term
What are some considerations for Hydrocolloids
Definition
-Characteristic odor with yellow exudate that looks similar to pus is normal when dressing is removed
-Allow 1 to 1 1/2 inch margin of healthy tissue around wound edges
-Taping edges will help prevent curling
-Freq of changes depends on amount of exudate
-Change every 3 to 7 days and as needed with leakage
- Avoid in wounds with infection or tracts
Term
What are some considerations for Hydrogels?
Definition
-Sheet form works well on partial thickness ulcers
-Do not use sheet form on infected ulcers
-Sheet form can promote growth of pseudomonias and yeast
-Dressing changes every 8-48 hours
-Use skin barrier wipe on surrounding intact skin to decrease risk of maceration
Term
Whate some considerations for foams?
Definition
-Change schedule varies from 1 to 5 days or as needed for leakage
-Protect intact surrounding skin with skin sealant to prevent maceration
Term
What are some considerations for alginates?
Definition
-May use dry gauze pad or transparent film as secondary dressing
-Change schedule varies (with type of product used and amount of exudate) from every 8 hours tp every 2-3 days
Term
What are some considerations for gauze dressings?
Definition
-Change schedule various with amount of exudate
-Pack loosely into wounds; tight packing compromises blood flow and delays wound closure
-Use continous roll of gauze for packing large wounds to ensure complete removal
-If too wet, dressings will macerate surrounding skin
-Use wide mesh gauze for debridement and fine mesh gauze for protection
-Protect surrounding skin with moisture barrier ointment or skin sealant as needed
