A few comments on this thread:

Yep, you are crawling with pathogens, and you are the source of the organisms most likely to infect your wound.

Triple antibiotic OTC lotions have a low incidence of allergic reactions and remain surprisingly effective against even most drug resistant organisms. They should not be used on extensive or deep wounds.

Hydrogen peroxide is not shown to reduce wound bacteria, but it also probably isn't harmful, either. The foaming action my provide some mechanical benefit in cleaning out a wound. It's use remains controversial.

Povidine iodine (betadine) is bacteriostatic, not antibiotic. It is used, diluted, in wound cleaning and irrigation.

Generally speaking, allowing a wound to dry out is not a good thing, as it may retard healing.

Wound cleaning and irrigation requires more than a spritz or two from a small container of nasal or otic saline solution. In the woods, where soap and clean running water are unavailable, use a large (60cc) syringe to obtain the necessary pressure and volume. Normal saline (0.9%NaCL in H20) is optimal, but clean water is fine.

For us lightweight backpackers, I recommend using a plastic Ziploc type bag full of filtered or treated water with one or two iodine swabs added, waiting ten minutes, putting a small pinprick hole in the bag, and squeezing.

Suturing is not as easy as it seems, and requires clinical judgment as well as the necessary technique. Leave it to experts. Use wound closing strips instead.

Consider taking a really good wilderness oriented first aid or EMT course if you go far away from medical care often.

I am not a doctor, nor did I stay at a Holiday Inn last night. This advice is worth exactly what you paid me for it. Consult your own darn doctor, you cheap bastard. ;-)
What I am is an experienced paramedic and disaster medical worker, as well as a long distance, solo backpacker, which means only that I have put some thought and training into treating wounds under less than optimal field conditions, and have done so, under the supervision of real doctors, perhaps thousands of times. Take it for whatever you think it’s worth.
