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.
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:
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.
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-based wound dressings are versatile as far as dressing change goes. It varies from daily to once in every seven days. Most of them have antimicrobial agents incorporated to limit spread of infections.These are available in different topical formulations such as paste, pads, freeze-dried sheets, gel, and collagen powder for wound care.
