Thought I should chime in as well. I am a doc, and I can tell you that for most wounds suffered in the field, the best way to treat them is to irrigate them out, leave them open, and apply a clean bandage, replacing when necessary. Very few wounds truly require closure, unless you are concerned about a scar. In the field, the main concern is infection, as mentioned above, and as one of my old vietnam era surgical professors used to say, the surest way to get a wound infected is to close it. This allows the bacteria a closed space to fester.
If you were to carry anything for wound treatment, I would recommend pressure bandages with gauze, and ace wraps to cover the dressing, and keep clean. A filter or iodine tablets for clean water, and a splint for extramity wounds.
