I've been treating a patient's legs with a Profore 4 layer wrap. She has venous stasis edema (without weeping or cellulitis) and a trauma wound that is not healing for the last 6 weeks. The trauma wound has a lot of drainage and is not known to and does not appear infected. I was thinking a wound vac might speed up the healing process (I LOVE them and use them a lot), but I've never used on IN CONJUNCTION with compression wraps. I can't find and don't know of any contraindications, do you? Have you seen this done before?
