Which product uses porcine gelatin as its base material?

• A. Surgicel Powder
• B. Floseal
• C. Avitene Flowable
• D. Surgiflo

Answer: (D)

Porcine gelatin provides a porous, biocompatible scaffold that stays at the bleeding site and concentrates clotting factors to speed up hemostasis. A flowable gelled matrix made with this material can be delivered into irregular wounds and then remain in place as it swells and supports clot formation, especially when combined with a coagulant like thrombin. Surgiflo is designed as a flowable matrix with porcine gelatin as its base, enabling easy delivery to complex bleeding surfaces while providing a solid scaffold for the clot to form.

Other options use different base materials: Surgicel Powder is oxidized regenerated cellulose, which aids hemostasis by a distinct mechanism; Avitene Flowable is microfibrillar collagen (typically bovine) that activates platelets rather than serving as a gelatin scaffold. Floseal also uses a gelatin-thrombin matrix, but the specific base material highlighted here is porcine gelatin in Surgiflo.
