You can have all the supplies in the world if you don't know how to use them it doesn't matter. Unfortunately definitive treatment for major trauma is always the OR. Doubt you're going to fit that into your first aid kit. (although I'm sure some people try!)
If I was trying to pack for a 20 day trip I might try to get some antibiotics, not sure how you're going to do that without a prescription though… and then you're practicing medicine without a license. A satellite phone would probably be more useful though...
The second post in the thread refers to the Grand Canyon Website, which is why I assumed we are talking about the Grand. A large part of the Wilderness First Responder training is the difference between front country medicine and backcountry medicine. And a lot of emphasis on evacuation decision making.
On the Grand an Evac is very expensive and a serious event for the NPS and not done lightly. So a sat phone is not used lightly..
So the major medical kit needs to be well thought out. You may need to take care of certain wounds for an extended period of time, up to 20 days.
As well as other serious non evac events.
