Devices and methods are disclosed for achieving hemostasis in traumatized patients. The devices utilize fluid impermeable outer surfaces and distributed pressure to achieve tamponade and hemostasis, primarily by exertion of pressure. The devices are capable of serving as carriers for throabogenic or antipathogenic agents. Peripheral haemostatic packing devices include optional adhesive hemostatic barriers to cover the entire wound area over the hemostatic pack. The hemostatic packing devices may be placed and removed by open surgery or laparoscopic access without generating excessive re-bleeding, and may further comprise antimicrobial or thrombogenic regions.

What is claimed is: 1. A device adapted for packing a wound and achieving hemostasis comprising: a three dimensional pack, said pack comprising a soft, pliable substrate at least partially covered with a fluid impermeable covering; a releasable attachment means adapted for releasably securing the pack to other packs; and anti-pathogenic agents disposed on the covering. 2. A device adapted for packing a wound and achieving hemostasis comprising: a three dimensional pack said pack comprising a soft, pliable substrate at least partially covered with a fluid impermeable covering; a releasable attachment means adapted for releasably securing the pack to other packs; and haemostatic agents disposed on the covering. 3. A device adapted for packing a wound and achieving hemostasis comprising: a three dimensional pack, said pack comprising a soft, pliable substrate at least partially covered with a fluid impermeable covering; a releasable attachment means adapted for releasably securing the pack to other packs; and a plurality of indentations filled with haemostatic agents. 4. A device adapted for packing a wound and achieving hemostasis comprising: a three dimensional pack, said pack comprising a soft, pliable substrate at least partially covered with a fluid impermeable covering; a releasable attachment means adapted for releasably securing the pack to other packs; and a plurality of indentations filled with anti-pathogenic agents. 5. The device of claim 1, 2, 3, or 4 wherein the device substrate comprises a water swellable hydrogel and a fluid permeable region on at least a portion of said outer surface of said device. 6. The device of claim 1, 2, 3, or 4 wherein the substrate comprises cotton gauze. 7. The device of claim 1, 2, 3, or 4 wherein said substrate comprises foam. 8. The device of claim 7 wherein said foam comprises polyurethane, polyvinyl chloride, polyethylene, polyvinyl acetate, silicone rubber, polyvinyl chloride, polymethyl methacrylate or a copolymer including one of these materials. 9. The device of claim 1, 2, 3, or 4 wherein said substrate comprises open-cell foam. 10. The device of claim 1, 2, 3, or 4 wherein said substrate comprises closed-cell foam. 11. The device of claim 1, 2, 3, or 4 wherein said substrate comprises silicone oil.
