When I was guiding down river, one of the Assistants managed to slash his thigh with chainsaw kickback. It looked like a bear slashed his leg with 4 ragged slashes.
The boat was not due back to check on us for another week. We washed out the cuts as best we could with boiled water, then I handed him the bottle of betadine and made him pour it over his leg.
After he quit jumping, cussing and swinging his fists around camp, we super glued his leg back together and butterfly bandaged with some duct tape strips. I checked his leg every evening and swabbed it a bit more with betadine, then covered with bag balm and he recovered very well with no infection.
We were lucky.
