I used superglue once to glue a cut along my hand and thumb was over a 3 hour drive to hospital had no problems with it it even healed without a scar and the Dr was pleased with my quick thinking as it had needed stitches but by the time I was able to get to him it had healed enough that he left it alone and just wrapped it up :-)

yes superglue is used in surgery, but it's a special hospital grade glue and used when doing bone work with adding metal to bone, my back surgen used a special type of superglue bond when I had my back surgery 13 years ago.
