What you need to know about collagen wound dressings

By Nancy Morgan, RN, BSN, MBA, WOC, WCC, DWC, OMS

Each month, Apple Bites brings you a tool you can apply in your daily practice.

Description

Collagen, the protein that gives the skin its tensile strength, plays a key role
in each phase of wound healing. It attracts cells, such as fibroblasts and keratinocytes, to the wound, which encourages debridement, angiogenesis, and reepithelialization. In addition, collagen provides a natural scaffold or substrate for new tissue growth.

Collagen dressings stimulate new tissue growth and encourage the deposition and organization of newly formed collagen fibers and granulation tissue in the wound bed. These dressings chemically bind to matrix metalloproteinases (MMPs) found in the extracellular fluid of wounds. MMPs normally attackand break down collagen, so it’s thought that wound dressings containing collagen give MMPs an alternative collagen source, leaving the body’s natural collagen available for normal wound healing.

Indications

Examples of wounds that may benefit from a collagen dressing include:
• partial- and full-thickness wounds
• wounds with minimal to heavy exudate
• skin grafts and skin donation sites
• second-degree burns
• granulating or necrotic wounds
• chronic nonhealing wounds (to jump-start wounds that are stalled in the inflammatory phase by reducing mediators of inflammation).

Contraindications

Don’t use collagen dressings in the following circumstances:
• third-degree burns
• patient sensitivity to bovine (cattle), porcine (swine), or avian (bird)
products
• wounds covered in dry eschar.

How to apply

Some collagen products will require a secondary cover dressing. Application technique varies based upon manufacturer recommendations.

Frequency of dressing changes

The frequency of dressing changes varies depending on the brand, but ranges from daily to every 7 days.

Formulations

A variety of topical formulations of collagen are available, such as freeze-dried sheets, pastes, pads, powder, and gels. Some dressings include alginates or even antimicrobial additives. The collagen source varies—bovine, porcine, or avian.

Examples

BGC Matrix®; BIOSTEPu Collagen Matrix; Catrix® Wound Dressing; CellerateRX® Gel or Powder; ColActive® Plus; Excellagen®; FIBRACOL® Plus; Promogran Prisma® Matrix; Puracol® Plus; Stimulen™ Collagen Gel, Lotion, Powder, or Sheets; Triple Helix Collagen Dressing

The HCPCS (Healthcare Common Procedure Coding System) codes for collagen dressings are A6021-A6024.

    I would like to know what is the best way to apply purcol (collgen) to a round wound in my stomach.
    I have looked for examples and can’t seem to find any. The round wound comes from a second infection after I had hysterectomy. It is right in the center of my incision. First used gauze with dakins( 1/2 gauze) changed twice daily. Also used rolled gauze with dakins on main or first incision.
    Went to wound Physician and he changed my dressing to purcol. Would like advice on how to fill hole with this new collgen. Thank You

    My husband is diabetic and got cellulitis on all toes on one foot a year ago. Today he ended up with a blister on his heel from the inside sole of his shoe coming apart and the seam part rubbing it, he thought it was something in his shoe. I still have some of the puracol plus ag left from last year, would I be jumping the gun if I went ahead and put a little of it on the part of the blister that busted? I have the Puracol Plus AG pad type thing.
