As a wound specialist, wet to dry dressings should be a thing of the past. WTD was used to debride, and in the true sense of the dressing, should be left on until dry and then pulled of (while dry) to debride. The problem with this is that it will also pull off the good granulation tissue!! Also, wounds need a moist environment and correct temp for healing, and each time a dsg is changed it takes the wound 4 hrs. to get back to the correct temp. Therefore, doing a WTD dsg 3-4 times a day really cuts down on the healing time!! Unfortunately, nurses (myself included) would have an easier time milking ducks than to get a plastics MD or surgeon to change his ways. In the case mentioned at the start of this thread, I maybe would have used an alginate, or an alginate with silver in it (to cut down the bacteria) and then a foam such as allevyn. This type of dsg can stay on for a number of days, I prefer to change every 3 days.
