The most serious wound I have had to administer first aid for when camping was an almost severed finger. Gauze and adhesive bandages kept everything intact until he was able to get to the emergency room.

I think having something for shock would have been good as I think he was about to go into shock. After getting him seated I gave him water while I wrapped everything up and talked to distract him. If I had coffee ready, I would have given him some.

What do you guys suggest to have in a FAK for treating shock? I know at that point, he wasn't thinking straight. I am thinking if I was by myself, what could I take to help keep my head together. Caffeine tablets?
