Avitene is a proprietary name for a type of absorbable hemostatic agent used in surgical procedures. It is a sterile white sheet or powder composed of freeze-dried bovine collagen, which is derived from cow tissues and specifically processed to remove any antigens that may lead to an allergic reaction.
As a hemostatic agent, Avitene is primarily used to control bleeding during surgical interventions. When applied to a bleeding area, it quickly absorbs the blood and forms a stable gel-like substance that adheres to the wound site. The gel forms a mechanical barrier that seals the wound, preventing further bleeding. Additionally, Avitene promotes the natural clotting process by concentrating platelets and enzymes involved in clot formation, thereby accelerating the overall hemostatic response.
The absorbable nature of Avitene is a significant advantage, as it eliminates the need for subsequent removal procedures, reducing patient discomfort and wound complications. Over time, the collagen sheets or powder gradually break down and are absorbed into the body, leaving behind no remnants or foreign materials.
Avitene has proven to be an effective tool in surgeries involving various medical specialties, including cardiovascular, orthopedic, and general surgery. It is especially beneficial in procedures where direct pressure alone is not enough to control bleeding effectively. However, like any medical product, Avitene should only be used under the guidance and direction of a trained healthcare professional.
