If you have the staples, have the staple remover.

Maybe add clindamycin? You know sometimes they double dose with metronidazole, or if docs are worried about toxin production.

I would double, or triple, the 4" roller gauze. Add maybe 12-24 2" or 3" too, b/c the 4" is sometimes too much.

More tape - it goes fast (ask a nurse)

Doculax?

Albuterol MDI?

WHO oral rehydration salts? Missouri doesn't exactly have nice dry summer-time temps.

Interesting thought on the Traction splint. You plan on leaving a person in that for 6-12 weeks? Maybe some sort of splinting supplies for stabilization, not just traction. Plus, lots of EMS and fire dept's will put a cardboard splint around a traction splint anyway.

OB kit.

1 or 2 packs of bloodstopper product (Celox, etc).

1 Asherman chest seal
