Nitrous Oxide during Abdominal Surgery, Yay or Nay?

I've thought about this and I can't seem to get a straight answer out of anyone. Obviously, you don't want to use nitrous in closed noncompliant spaces (middle ear and intracrainal cases), but what about using it during lap appy/choles, robo hys or during wake ups after a exlap/nephrectomy etc. How significant is the expansion effect for exposures less than 1 hour in duration?
