Fluid Irrigation quesitons

[Norfin]

What constitutes a large volume of irrigation for a procedure?  What would you say the average amount of irrigation is in a standard procedure?  At what point would you want to have a large fluid suction device to collect irrigation(assuming you only have 1 device to share for many ORs) instead of using canisters?  What surgeries do you know use large volumes of irrigation?  Thanks!
