sterile gloves for doing procedures such as removing sutures and such is a waste of time. the wound itself is dirty (aka germy) i used to work on a "wound care" med/surg unit... multiple dressing changes on many patients a day. we didn't use sterile gloves for that. think about the condition of the wound, most of the time a patient with staples or sutures by the time you are ready to remove them they are open to air. the air itself is not sterile, nor is the bed sheets or anything else that wound is touching. i would however recommend using strict sterile procedure for things like central/picc dressing changes, inserting a foley etc. these are instances when contamination can mean major complications. for regular iv starts, accessing saline lock, and dressing changes regular clean gloves are sufficient.
