While deferring to the medical professionals here, I will reiterate what I always say in these threads: Advanced trauma kits are worthless if you don't have the proper skills to use them. A splint is one thing, but a tourniquet is something you use as an interim fix until medical professionals arrive; and without training and practice, those nasal tubes can turn into something for which your victim requires real medical attention. I've had advanced first aid and basic dive medic training, and we never covered nasal tube insertion.
If you want a trauma kit and add advanced first aid/EMT classes to it, bravo. If you buy one because of all the cool stuff thinking you're going to do field surgery without having had any training, best to stick to basic first aid and some well thought out and safe medications (pain relief, antiseptics, etc.). JMHO.
This is true. I have had this discussion with my friend. His view is to carry (in his vehicles) a minimal trauma kit, sufficient for treating ONE gunshot wound at a shooting range or IDPA competition.
My view is a bit longer term, perhaps not TEOTWAWKI stuff, but certainly aimed at things like natural disaster situations and resultant evacuations. I want things in my kit to treat what might be encountered. I may not know how to use it (like the nasal tubes), but they're in the kit so if a doctor or paramedic shows up but doesn't have the supplies, my kit can provide the supplies and the other good Samaritan can provide the expertise.
Amazon has some soft first aid kit pouches that are similar to the one in that review, but slightly larger in size and capacity. I've bought two of those that I'm setting up as my everyday vehicle carry kits. For a longer term trauma kit, I went with a single-strap "tactical" backpack style sling bag.
For a kit that could be good for two years or so, I don't think you can plan on using it for a single emergency and then restocking. The kit in the review, for example, has a single roll of tape (very small) and a single roll of coban (cohesive bandage -- the self-adhering Ace bandage stuff). I've bought bulk packs of coban in both 2-inch and 3-inch widths, and I'll put a couple in each vehicle bag, and probably several in the long-term SHTF bag.
For the antibiotics, search for "fish+antibiotics" or "bird+antibiotics." Here's one potential source:
https://www.chkadels.com/fish-antibiotics-4577The problem with the antibiotics is knowing which to use for what. But, if you have two or three in your kit, you may be able to obtain guidance from someone/somewhere as to what's appropriate in a given situation.
[Edit to add] That source also has trauma kits:
