Well, when you get beyond "gauze sponges" there are all sorts of other dressings - the abd pads, Maxi pads, etc. The goal on my leg, for instance, is to only change the dressings 2x/week. The problem is, it exudates more than even doubled up 4x4s can handle over those 3 days, and the type of exudate I have is actually corrosive to the wound - causes it to macerate, and get larger. So, I get to play with all sorts of "fun" stuff - Algenate dressings (with and without silver), Iodasorb gel and pads, etc etc

As my wound care specialist says "In this field, the patient eventually becomes an expert in their own wound - they alone know how the wound feels that day, and that changes how you treat it, day by day"
