I don't know the answer to your question, but wouldn't submerging a
recently amputated limb in ice cold water of any kind cause the blood
vessels to constrict and maybe spasm? That would reduce blood flow to
the healing wound, which seems like it could cause problems... but I
may be completely wrong... just speculating.

I'm not really sure but I think that's what the moderator at madsci was
saying too, that the water being ice cold and having free radicals
would cause too much damage to be of any use. But a ph neutral super
oxidized water like Dermacyn was being used to treat chronically
infected wounds.

I hope this wasn't confused when I sent the question to madsci with
some of the quackery going on with "super oxygenated" water!
I thought hypothermia on an amputated limb or donor organ was good for
slowing the metabolism. That's the reason I included the phrase "ice
cold" in the sentence. I just thought about how donor body parts are
put on ice when transported. Maybe I should ask again on madsci with a
different question?

I don't know what you mean by "superoxidized water", but I suspect it's
a typical quack term for a solution of hydrogen peroxide.
Anything that kills bacteria by oxidizing them to death is going to
be even more destructive to living animal cells.
Submerging live tissue in water that isn't buffered appropriately will
kill even more cells by osmotic shock. Generally the best thing to
heal an open wound is to clean it, close it as much as possible, and
cover it to keep it clean, and for some types of wound, moist.

There's a big difference between disinfecting unbroken skin, which is
covered by layers of tough, fairly impermeable dead cells, and exposing
delicate live tissues to harsh germicides.

I saw one site that had a table of many quack water remedies and a few
sentences explaining why it was quackery. I remember microcyn was one
on the list because as the author of the list put it, microcyn was
"just bleach." I don't think it is bleach or hydrogen peroxide. I
finally found the website of the manufacturer:

And for what it's worth here is a wired article on it.

Ah, it IS "super-oxygenated" water, my mistake. Looks like it's
nothing new either! Check the wired article. Hehehe "The solution also
might be used as a hospital hand wash -- a user-friendly, non-caustic
disinfectant would benefit patients if it enabled medical workers to
wash their hands more often..." Now, about those burn victims...
