The facility that I work at only has a wound care nurse M-F and the regular med-surg nurse does the daily dressing changes on the weekend. Usually there are extra dressings in a bin in the patient's room. The patient had a large/deep abdominal dehiscening wound. It was listed to place Mepitel in the base of the wound. The charge nurse and I couldn't find any in the patient's room or supply room. What is the difference between Mepitel and an oil emulsion dressing?
