I just watched a webinar on LE edema by Jeri Lundgren ( She trained the state surveyors on what to look for) Any way, she says Ace wraps are not good for edema. If you can get the doctor to change the order, Unna boots are the best for reducing edema as well as elevation (depending on the underlying cause of the edema). Unna boots are spiral wrapped with 50% overlap and they are rated for compression. After the edema is under control, then compression stockings should be used to maintain. Why does she have so much edema? Has she been diagnosed with CHF? Does she have venous insufficiency? There a lot of meds that cause fluid retention.
