Which product uses a porcine gelatin matrix as part of its composition?

• A. Surgiflo
• B. Floseal
• C. Arista AH
• D. Tisseel

Answer: (A)

Porcine gelatin matrix provides a swellable, biocompatible carrier that forms a physical barrier and concentrates clotting factors at the bleeding site. Surgiflo is a premixed flowable hemostatic matrix that uses this porcine gelatin matrix as its base, delivering it directly to the site of bleeding. When applied, the gelatin absorbs blood and expands to fill irregularities, while the thrombin component accelerates the coagulation cascade to form a stable clot more quickly. This combination—a porcine gelatin-based carrier with thrombin—is what distinguishes Surgiflo in this set. Arista AH is a cellulose-based hemostatic powder, and Tisseel is a fibrin sealant rather than a gelatin matrix, so they do not use a porcine gelatin matrix as their core component.
