I’ve done the same, hording medical supplies.Used HIBICLENS ($10-20 a bottle) to clean/sterilize any deep wounds . We keep a bottle or two in the first aid.
If you have cut on hand, as described by OP…. Pour generous amount into wound and all around, hold over sink. Use CLEAN washcloth or gauze pads and soak with Hibiclens and hold on wound for 30-45 secs….then close with superglue, butterfly stich or sutures if you have access. Cuts on fingers can be cleaned by pouring in a cup and stick finger(s) in for a minute or so.
We keep lidocaine, sutures, syringes, etc. I had started collecting stuff a couple years back …..my ole lady put together a hella first aid kit out of a new Plano Tackle box. We started adding stuff like the sutures, sterile instruments, etc., Its not easy to get a few things but being creative you can get anything you need within reason..
After I was taken off antibiotics I still had 2 more refills, so I filled em each month. Good stuff to keep around. If medication gets Scarce like other things lately, antibiotics, pain meds and anti inflammatory drugs will be nice to have for emergencies.
