I think the biggest problem with this is, it was done "on purpose." If this had been a true accident, the tone of the whole thing would be different. Yes it was stupid to do on purpose, but if it was a real emergency, and a way more serious wound (say a severed artery), I should think this technique to be a little too time consuming. But, it is effective at both cleansing and cauterizing the wound.
I like to carry a pack of salt with me in my altoids tin for this reason (or seasoning a steak
). Maybe seal it up with a pack of sugar, or even some super glue. Then again, I also carry some sutures and needles with me for serious cuts.
Be careful with cleaning a wound with water. It better be sterile and you better know for sure that it is sterile before you use it. Otherwise, you could make the situation worse by adding a dangerous contaminant to the wound. This may sound disgusting, but you can always pee on your wound. Yeah, that's right, I said use URIN! Pee is sterile unless you have a bladder or kidney infection.
