Richard, thanks for the article. Just a couple of additional things for people to consider when assessing their own first aid needs.
Consider Peptobismol tabs over loperamide if you are going to bring something for diarrhea. Pepto is typically more effective and also has antibacterial properties. Some don't even recommend loperamide/Imodium for infectious/bloody diarrhea.
Consider Bacitracin ointment instead of Neosporin. A good number of people are allergic and can get a rash from the neomycin.
Consider bringing just 4x4 guaze and 4" ace wraps/tape. This can treat anything a 2" ace wrap and rolled guaze can plus more.
I personally don't bring any bandaids or alcohol pads. If someone can tell what these are good for treating, then I am all ears. I want to like them, because they are both light in weight. But the bandaids are occlusive yet still let dirt in, creating a dirty, moist environment over the wound. Unless you are diabetic on insulin (or maybe plan on removing fingernail polish in the field because you have an infection at the edge of our fingernail), I just can't think of any medical use for alcohol swabs?
In addition to the Benadryl that Richard mentions, consider bringing 81 mg chewable aspirin if you or your hunting partner is over 40 (in case of chest pain/MI).
4x4 gauze srubs with filtered water poured into the wound are good for cleaning just about any wound that you might encounter. If you can not see fat in the base of the wound, you should then have no problems closing the wound right away with Dermabond, or benzoin/steristrips which is what I prefer for non-scalp wounds. If the wound extends beyond the deeper skin layers down into the fat, and you are medically inexperienced, then it is probably best to just clean the wound and approximate it with a bandage/tape without closing permanently. I have treated litterally thousands of wounds in this manner with water or saline scrubs with zero infections.
And finally, I personally don't carry a tourniquet on solo or 2-person backpack hunting trips in the lower 48, because death from blood loss is typically not what kills people in the backcountry. Which makes sense, considering how well our major arteries are protected and how well the average person clots. Not only that, but for a tourniquet to be a useful part of a kit, a person would have to have life threatening bleeding from and extremity which is distal enough to utilize the tourniquet. Instead, the major causes of backcountry death include: falls, avalanches, drowning, MI, getting lost, hypthermia, dehydration, snowmobile accident, bear attacks, trees and rocks falling or rolling on you, lightning, homicide, and gastrointestinal bleeds. However, if I was a hunting guide in Alaska on a river trip with a bunch of hunters from California, then I would definitely rethink bringing a tourniquet.
