Freezing to stop bleeding?

I was thinking the other day about how to stop bleeding from major injuries. I remember hearing that super glue is used, but I can't see how this would work if the blood is pouring out. I wonder what the impact of pouring on a very cool liquid (e.g. liquid nitrogen) would be. Would it freeze the wound, stopping bleeding for long enough to allow a clot to form? Or perhaps the combination of a very cool liquid and then super glue would work, the cool liquid slowing the flow enough for the super glue to work?
