Lots of good ideas being kiced around. As an RN I will not go into all of the details of my med kit but its extensive and I have access to stuff that
you could not get OTC like IV stuff and fluids, albumin etc.
But, you can still put together a good kit and when doing so you should take several factors into account:
1) How big? I took my family, local relatives, and neighbors and doubled it. However, I also include a backpack with a more mobile version fo the kit
in case we are forced from our location. Being anal, the kit is divided into 4 Sections. I can tailor the mobile kit to the needs of the party
Basic first aid: Bandaids, ointment, yes crazy glue (known as demabond in medical applications. Just like the kind you may buy to put in your care
Trauma: Gauze, bandages, sterile 4x4 and 2x2's, sterile non latex gloves, gowns, masks, compression bandages, sterile water, powdered collagen
Drug: 3 sets of code medications (Epinephrine, atropine etc.) IV antibiotics (Rocephin, Vancomyacin, Gentamyacin should provide gram - and gram +
coverage), Oral antibiotics (Zithromax) some other stuff that I will not get into
IV: IV catheters and fluid etc.
Now the last 2 are not as practical unless you are in the healthcare field, the first two are. You can NEVER have too big of a kit IMHO BUT you need
to be able to go mobile with it.
