I'd just procure the strongest co-codamol you can find and hope for the best.
Good advice. Did the mines-rescue course near Durham a few years back and am a first aider at the local dry ski slope (get to practice my medskillz at least once a week).
A good quality bag of skag would be ideal, but Tramadol / Co-codamol would suffice. My wife's mate fell off her bike during a two week tour of Wales a few years ago. Seeing her in a pool of claret, mostly emenating from a large scalp wound, I fell apart until my wife spat, "You're the first aider, DO SOMETHING!!". At which juncture, the (minimal) training all flooded back and the first aid bag was produced.
Just the physical presence of kit you're familiar with can make a huge difference to your reaction - triangular bandages, dressings.... I was able to stop the bleed until a passing nurse came along and took over (I was a tiny bit annoyed!).
It's easy to treat someone you don't know. It's very hard to apply your knowledge to a good friend in pain......
