Umbilical tapes from the OR work really well too, plus some come with a little foil tab that makes threading it between the ring and the finger really easy. Just wrap to compress, lube, and pull! One thing we did find out- if the ring has those little nubs on the inside that help keep it from spinning and is tight enough to need this trick, you are better off just cutting it off. We didn't realize a patient had these on his ring, and when we took it off (fortunately after he was already anesthetized), the nubs caused some pretty nasty damage to his finger. I now make it my routine that when we have a patient with a ring that won't come off to ask them if it has these nubs before trying the removal trick. And if your patient is destined for surgery and it's not absolutely imperative to take it off beforehand, this can be pretty painful so being asleep is also a good idea.
