Hi Dawn,
I would use fluids, just not lactated ones. Straightforward saline may be used - 0.6 - 0.7% saline may be considered reasonably isotonic, 0.8 - 2.5% (but I'd stay in the lower end of that range) saline can be used as a hypertonic solution to try to reduce bloat, but it needs close monitoring.
As Ed says, there is a more detailed discussion in Wright and Whitaker's book, if you have access to that.
