The OR is not the place to mark the surgical margins. The tissue should be
carefully dried before applying the ink to prevent running. A fresh
specimen handled hurriedly does not produce the best results. It's also
better if the ink is smeared that I'm the one who does it and knows where it
is smeared. I really prefer the suture marking system or a simple diagram.
