the ins standard for dressing changes are that gauze dressings that prevent the visualization of the insertion site should be changed every 48 hours or if the integrity of the dressing is compromised. if a transparent semipermeable membrane dressing is used change is dependent on the facility policy as well as manufacture use and directions of the dressing material. otherwise, ins standard is that the transparent dressing on central venous access devices should be changed at least every 7 days or if the integrity of the dressing is in any way compromised (page s44-45).
