In CVICU you will some times have a patient with an open chest (OPEN, as in the retractor is still in holding the ribs apart, but covered with a sterile dressing)(they are paralyzed and heavily sedated). These patients cannot
be turned (you don't want anything to fall out!) so you do the best you can. Some times you can shove clean linens under the legs, head, butt - depending on how stable they are, but you cannot roll them. If they poo, you can get it from the front, between the legs. In a real pinch (perhaps, they are laying in a pool of blood and you know that they will not be closed up anytime soon) you could (perhaps) levitate them
if you have 6 to 8 people to help. Get everything ready, so then it's 1-2-3 UP! Quickly swap out the linens, wipe the skin briefly, grab your stethoscope for a 5 second listen, and DOWN! she comes.
I don't know if I would levitate someone with a broken back. Depends on what kind of bracing they have, I guess.
