Which product uses bovine gelatin as its base material?

• A. Floseal
• B. Avitene Flour
• C. Surgiflo
• D. Avitene Flowable

Answer: (A)

Gelatin-based hemostats rely on a gelatin matrix as the main scaffold that stays at the bleeding surface and helps form a stable clot. Floseal uses a bovine-derived gelatin matrix as its base material, paired with thrombin to accelerate the clotting process right at the wound site. This gelatin base is what distinguishes Floseal from Avitene Flour and Avitene Flowable, which are based on microfibrillar collagen from bovine sources rather than gelatin. Surgiflo also uses a gelatin-thrombin matrix, but the question emphasizes bovine gelatin as the base material, which Floseal specifically provides. So the product with bovine gelatin as its base is Floseal.
