What type of treatment would you use on an insertion site of a g-tube that has become infected? Our wound nurse is using 4X4's cut with a space to fit around the site. The 4x4 strings are getting caught on the plastic thing the tube fits through and also are going down into the fistula. The dressing is total yuk by the time it gets changed. We talked to her about sponge dressings but she doesn't like them.
