I have had occasion to use superglue to close wounds on myself and on animals. Unless you can make certain that the wound is sterilized first, I wouldn't recommend it. You can't do it if the blood is still flowing through the wound either. The last time I did this was when an elderly freind was helping me dress an elk, and he cut my hand with the knife. After I cleaned the wound and it coagulated, I applied the glue and pushed the skin together until the glue set. The glue held the wound shut and kept it from opening up the rest of the day while I continued to dress the elk out and tend to camp chores. A couple days later, the glue separated and the wound was sufficiently knitted on it's own. Later on when I got home, I opened the wound back up and inspected and sterilized it, then dressed it. The doctor later said I could've used a few stitches, but it was otherwise okay, although it would leave a bragging scar (mostly from re-opening it up).
I have a good friend who is an ER doctor, and he doesn't recommend this treatment for the same reasons as mentioned in the other posts on this thread. Mine was a field expedient because I needed to get the elk taken care of, and in other cases for similar cause.
