If you're satisfied the IV's were patent then really the only explanation for that would be a bad lot of sux. Probably too late now, but you could see if the lot numbers on the bottles were the same. We occasionally get a batch of drugs where the effect isn't nearly what you expect it to be. This has happened on numerous occasions with rocuronium. Whether related to the manufacturer (several different generic brands) and their quality controls, or it being out in a room temp or higher environment for too many weeks, I don't know.
If the problem is they just don't relax, it's probably bad drug. If the problem is something like a trismus, where they really lock up their jaws, that's different, and that is occasionally seen along with MH.
I don't know any more about it than what I posted. It was investigated above my head. The only reason I know about it is because I used sux during that time and they wanted to know if it worked or not. I wanted to know why they wanted to know.
