While it may seem silly to some, I believe I'd find myself more comfortable inserting a urinary catheter if I was able to ensure
the sterility of my hands. The entire technique of open-gloving for sterile procedures always seemed shifty to me, because it ultimately leaves you with very little sterile length on the hands given that it's extremely difficult for even experienced nurses to completely prevent the outer edges of the cuffs from touching the bare arms (whether it be due to rolling, etc, or whatever)
With sleeves, you'd have a much wider range of movement with your hands, and you would also be CERTAIN that the entire area around your hands is sterile, since the gloves would stay in contact with the sterile sleeves even if they rolled nonstop, since the outer cuffs of the gloves are sterile until you actually touch them with bare hands (regardless of what they are "considered"). If you use the sleeves correctly, there's a lot of wiggle room in the cuffs without contaminating anything.
What do you guys think?
