Collagen Dressings

Collagen dressings are designed for minimal-to-heavy exuding wounds. They absorb exudates from the wound while at the same time maintaining a moist wound bed conducive for optimal healing. They are derived from animal sources such as bovine, equine and porcine and speed up the recovery period due to the growth of new collagen at the wound site. Collagen dressings for wound care usually require a secondary dressing.

How Collagen wound healing works?

Collagen dressings stimulate new tissue formation and help heal necrotic wounds, skin grafts and second-degree burns. They promote the deposition and organization of newly-formed collagen fibers. Collagen wound healing provides a framework for building of new tissues and basically works on three premises:

  • Debridement - Removal of necrotic tissue
  • Angiogenesis - Growth of new blood vessels
  • Re-epithelialization - Migration of epidermal cells from wound edge towards the center

When to use Collagen Wound Dressings?

Collagen wound dressings are suitable for use on necrotic or granulating wounds and wounds with minimal-to-heavy exudates. Wounds which are chronic and non-healing may also benefit from such dressings which can jump-start the healing process.

You can also use collagen for wounds like:
  • Venous ulcers/foot/leg ulcers
  • Diabetic ulcers
  • Pressure ulcers
  • Partial/full thickness wounds
  • Surgical/post-operative wounds
  • Donor sites
  • Acute/traumatic wounds
  • Laceration/abrasions
  • Partial thickness burn/second degree burn
  • Superficial burn/first degree burn
  • Arterial ulcers
  • Low-to-moderate exuding wounds
  • Moderate-to-high exuding wounds

Some common features of Collagen Dressings

The matrix metalloproteinases (MMPs) available in the wound’s extracellular fluid usually break down the natural collagen in the body thus inhibiting wound healing. Collagen dressing is said to attach to the MMPs providing an alternative collagen source. This allows the body to provide more collagen to a wound for a longer period of time.

Collagen wound dressings have following features and benefits:
  • Absorbent
  • Easy to use
  • Produce an ideal moist environment conducive to wound healing
  • Lower irritation and discomfort
  • Reduce occurrence of wound infection
  • Heal a variety of wounds

Collagen dressings should not be used on wounds which are:
  • Dry and covered in eschar
  • Third-degree or full thickness burns
They won’t even work for some individuals, if they have sensitivity to products that contain:
  • Porcine
  • Avian
  • Bovine
