Superglue does work. But if you watch the video in the article there is no way you could apply Superglue to a cut that deep and that long.

Couldn't you just use a piece of waterproof [well blood-proof] material lathered with superglue and slap it on; basically a superglue band-aid. That would contain the bleeding and be cheaper and easier to apply, presumably, than this solution. It would have the same problem of internal bleeding as well of course.

With the OP's solution how do you remove it to treat the injury?

It would contain the bleeding but it wouldn't stop it.

I understood that was what the gel in question did, contained the bleeding to prevent bleeding out before medical aid could be given. But, that it was not preventing the bleed from continuing internally.

As you may guess I have basically no medical training so I may well have misunderstood.
