No offense, but I think I'll wait until the "study" comes out that verifies this. Until then I'll still carry a vial of Aristocort around....never know what you might need it for
My main things that I take into the back country are, water, more water, even more water, packets of gatorade, multiple layers, bug spray, more bug spray, sunglasses, a bag of LR for each person's right front cargo pocket along with a 1.25" 16 guage setup with tubing. I carry an epi pen, lots of sunblock, and a really sharp knife for all kinds of things as you can imagine. I carry on my belt a hemostat, forceps with no teeth, and a 380 Sigma S&W concealed beneath a neoprene abdominal sleave. I have 2 old maleable splints, a 7.5 ET tube, and some Coban...4 rolls. I usually carry a flask of Stoli for when I finish a day of long hiking, and I keep some Advil around as well. Zantac...because someone on the trip with the change in foods is going to start complaining constantly about their GERD....and it helps to go along with the Claritin redi tabs I have in case someone has the strange exposure rash that doesn't seem to read the books. Lots of Eucerin paste in a ziplock bag for antichafing....and some moleskin to patch everyone's feet up...but you need some Mastasol or Benzoin for it to stay on for several days. If I am out for more than a few days I usually bring this one bottle I have that literally has 2 of nearly any class of drugs imaginable that I have accumulated over the years. I keep it in the fridge and foil wrapped and the stuff has never gone bad....thus far. Its nice to have a broad spectrum Augmentin or Levaquin when someone starts with some really bad cellulitis.
Things I don't waste space on that I have seen a lot of people try and lug around.....bottles of alcohol or peroxide...that could be more water weight. I never carry a stethescope or BP cuff, because you can assess how stable someone is with peripheral pulses and you can listen with your ears if you need....without a steth against their chest. I have had a kit I have kept with me since the Gulf War and I have modified it to suit more modern needs.
