And that's why, when I was leading youth on trips, I also carried a large pkg of steri-strips, a tube of surgical glue (basically medical grade superglue), and a skin stapler. the first 2 got used fairly often, usually when some kid used a ubersharp pocket or sheath knife to cut salami..
The surgical stapler has only been needed once, and not for my group- a student from another group used a hatchet while standing up with the predicted result, Yup, he stuck it in his calf. That stapler turned a full blown "drop everything, call for evac" medical emergency into a case for being tended to while the group took the time to pack up and self evacuate thanks to saline irrigation, 9 staples, and some wound dressing. Apparently I did a good job as when the head teacher called me after he said the hospital elected to leave my staples in and just cleaned and re-bandaged it
I'll bet the story about that accident grew into a harrowing attack by a bear or a crazed wildman when told to the girls later...
