We aren't supposed to be flipping things, but in the heart ORs, that would mean we'd need two people scrubbed so one could be setting up while the other takes the opened supplies, plus two more to open the supplies in order to be set up on time. We use two tables instead- one that is used at the sterile field, and a second table that we flip things onto. There are things that absolutely no one will flip and will have the scrub person take, but then all of our instruments come in sterile pans, not peel packs. What we flip: sutures, extra sponges, towels, gowns, gloves, some miscellaneous small stuff like extended bovie tips. Things that absolutely no one will flip: platelet gel kit ($$$$$), cooling jacket (just impossible the way it's packaged), cannulas ($$$$, plus it's on backorder and we have a limited supply), things that are just awkward or have a tendency to roll if flipped.
