The conflict I have in my mind, with putting together an emergency medical kit, is that a lot of the supplies expire. Granted, what's the point of having an expiration date on gauze (fairly sure it would still cover a wound after the expiration date...). And in a disaster, an expired IV tubing is more useful than no IV tubing at all. That being said, I'm hesistant to put a bunch of money into supplies, then have to either replace them every few years, or deal with a bunch of equipment that no longer does what it's supposed to. Or worse, works, but the packaging has degraded in time and now I'm using contaminated equipment and all of the post-apocalypse people I do something to get septic from my interventions and there's no antibiotic supply to treat them.
